  •                              UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF COLUMBIA
    RICHARD CARL MUELLER, et al.,
    Plaintiffs,
    v.                                               Civil Action No. 1:18-cv-01229 (CJN)
    SYRIAN ARAB REPUBLIC,
    Defendant.
    MEMORANDUM OPINION
    Kayla Mueller, an American humanitarian aid worker, was kidnapped, tortured, and
    executed by ISIS. Plaintiffs here are her mother, father, and brother. Claiming that the Syrian
    Arab Republic was responsible for Kayla’s injuries and death, they sued Syria under the state-
    sponsored terrorism exception of the Foreign Sovereign Immunities Act (FSIA), 
    28 U.S.C. §§ 1330
    , 1602 et seq. Plaintiffs served Syria by diplomatic channels, 
    28 U.S.C. § 1608
    (a)(4), and
    Syria subsequently failed to appear, 
    id.
     § 1608(d). Plaintiffs therefore now move for default
    judgment as to liability. See Pls. Mot. for Def. J. as to Liability (“Mot.”), ECF. No. 28. The Court
    agrees that Plaintiffs have demonstrated most of the elements of their claims, but before the Court
    can grant that motion, Plaintiffs must submit further briefing on their tort theories of liability.
    I.      Procedural History
    Between August 2014 and February 2015, three American hostages—James Foley, Steven
    Sotloff, and Kayla Mueller—were killed by ISIS. Sotloff’s family was the first to sue Syria in this
    district, claiming in March 2016 that Syria was responsible for Sotloff’s hostage taking, torture,
    and extrajudicial killing under the terrorism exception to the FSIA. Sotloff v. Syrian Arab
    Republic, 
    525 F. Supp. 3d 121
    , 132 (D.D.C. 2021). Likewise, in July 2018, Foley’s family “sued
    1
    Syria for Foley’s hostage taking, torture, and extrajudicial killing under the terrorist exception to
    the FSIA.” 
    Id.
     Those two actions were consolidated in September 2018 (hereinafter the Sotloff
    proceedings), and “Syria did not respond to either complaint or otherwise appear.” 
    Id.
     The Clerk
    of Court entered default against Syria in January 2019, and later that year, the plaintiffs in those
    proceedings moved for default judgment. 
    Id.
     at 132–33. The Court granted the plaintiffs’ motion
    in March 2021. See generally 
    id.
    This case also followed. Plaintiffs Robert Carl Mueller and Marsha Jean Mueller are
    Kayla’s father and mother; they are suing both in their personal capacities and in their capacities
    as the co-personal representatives of Kayla’s estate. See Compl., ECF No. 1, at ¶¶ 7–8. Eric
    Robert Mueller, Kayla’s brother, is suing in his personal capacity only. 
    Id. at ¶ 9
    . Their Complaint
    alleges wrongful death, battery, assault, false imprisonment and kidnapping, intentional infliction
    of emotional distress, survival damages conspiracy, aiding and abetting, and punitive damages.
    See generally 
    id.
    The Muellers served Syria through the Department of State’s diplomatic channels pursuant
    to 
    28 U.S.C. § 1608
    (a)(4). See ECF No. 16. The diplomatic notes were served on November 12,
    2018. 
    Id. at 6
    . Syria thus had until January 11, 2019, to respond to the Complaint, 
    28 U.S.C. § 1608
    (d), but it failed to do so. The Clerk of the Court therefore entered default on the Muellers’
    behalf, ECF No. 19, and the Muellers then moved for entry of a default judgment against Syria as
    to liability. See generally Mot.; 
    28 U.S.C. § 1608
    (e).
    Before entering default judgment in the Sotloff proceedings, Judge Timothy Kelly held a
    two-day evidentiary hearing in June 2020. See Sotloff, 525 F. Supp. 3d at 133. Two experts
    testified. Id. “The first expert, Dr. Daveed Gartenstein-Ross, is an anti-terrorism scholar and
    author who has worked, in various capacities, on issues related to violent non-state actors for over
    2
    a decade.” Id. “The Court qualified him as an expert on violent non-state actors generally, ISIS’s
    evolution from its predecessor organizations, and ISIS’s material supporters.” Id. “The second,
    Dr. Matthew Levitt, is director of the counterterrorism and intelligence program at the Washington
    Institute, a think tank dedicated to U.S. policy in the Middle East.” Id. “The Court qualified him
    as an expert on the Syrian government’s relationship with ISIS’s predecessor organizations and
    ISIS itself between 2010 and 2015.” This testimony is relevant to the current proceedings because
    the Muellers have asked this Court to take judicial notice of the experts’ testimony in the Sotloff
    matter as evidence in this action. See infra at 4–5.
    II.       Facts
    The FSIA does not permit the ministerial entry of a default judgment. Instead, the Court
    must evaluate the evidence to ensure that Plaintiffs have “establish[ed] [their] claim[s] or right[s]
    to relief by evidence satisfactory to the [C]ourt.” See 
    28 U.S.C. § 1608
    (e). “This requirement
    imposes a duty on FSIA courts to not simply accept a complaint’s unsupported allegations as true,
    and obligates courts to inquire further before entering judgment against parties in default.”
    Memorandum Op., Encinas v. Islamic Republic of Iran, No. 18-cv-02568, at 3 (D.D.C. Feb. 28,
    2022) (quotation omitted).
    The Court may look to various sources of evidence to satisfy this statutory obligation,
    including testimony, documents, and affidavits. See 
    id.
     “And a FSIA court may take judicial
    notice of related proceedings and records in cases before the same court.” 
    Id.
     (quotation omitted).
    Here, the Muellers rely on judicial notice of related proceedings and records, declarations,
    affidavits, two expert reports, government reports and press releases, ISIS’s ransom emails, and
    public remarks made by U.S. officials. See Exhibits 1–33, ECF Nos. 28-1–38.
    The first expert report provides Dr. Gartenstein-Ross’s opinion “on the evolution of the
    Islamic State . . . through the time of Kayla Mueller’s death; on ISIS’s responsibility for the death
    3
    of Kayla Mueller; on the conditions that Mueller faced while held captive by the militant group;
    and on the Syrian Arab Republic’s relationship with ISIS.” Exhibit 1, ECF No. 28-1, at 3
    (“Gartenstein-Ross Report”). Dr. Gartenstein-Ross testified on similar matters before Judge Kelly
    in the Sotloff proceedings, see Sotloff v. Syrian Arab Republic, 16-cv-724, ECF No. 41 (D.D.C.
    June 10, 2020) (“Kelly Hr’g Tr. Day 1”), and the Muellers have asked the Court to take judicial
    notice of that testimony. See Mueller, No. 18-cv-1229, ECF No. 29 at 2 (Proposed Findings of
    Fact and Conclusions of Law).
    The second expert report provides Dr. Levitt’s opinion on Syria’s support of ISIS and its
    precursors. Exhibit 2, ECF No. 28-2, at 1 (“Levitt Report”). Dr. Levitt also testified on similar
    matters before Judge Kelly in the Sotloff proceedings, see Kelly Hr’g Tr. Day 1; Sotloff, ECF No.
    42 (“Kelly Hr’g Tr. Day 2”), and the Muellers have asked the Court to also take judicial notice of
    that testimony, see Mueller, No. 18-cv-1229, ECF No. 29 at 2.
    A.      Judicial Notice of Evidence Produced in Prior Proceedings
    “This Court may take judicial notice of facts ‘not subject to reasonable dispute’ if they are
    ‘generally known within the [Court’s] territorial jurisdiction’ or ‘can be accurately and readily
    determined from sources whose accuracy cannot reasonably be questioned.’” Encinas, supra, at
    4 (quoting Fed. R. Evid. 201(b)). This rule permits taking “judicial notice of related proceedings
    and records in cases before the same court.” Fain v. Islamic Republic of Iran, 
    856 F. Supp. 2d 109
    , 115 (D.D.C. 2012) (quotation omitted). “Because of the multiplicity of FSIA-related
    litigation, courts in this District have frequently taken judicial notice of earlier, related
    proceedings.” 
    Id.
    As many judges on this Court have recognized, “evidentiary problems lurk when taking
    judicial notice of another court’s factual findings in a different case.” Encinas, supra, at 4. “Such
    findings are a court’s attempt to determine what happened; they are not a first-hand account of the
    4
    actual events.” Id. “As such, they constitute hearsay, and thus are considered inadmissible.” Fain,
    
    856 F. Supp. 2d at 116
    .
    But courts in FSIA actions “must be mindful that the statutory obligation found in [28
    U.S.C.] § 1608(e) was not designed to impose the onerous burden of re-litigating key facts in
    related cases arising out of the same terrorist attack.” Rimkus v. Islamic Republic of Iran, 750 F.
    Supp 2d 163, 172 (D.D.C. 2010). And as Judge Lamberth concluded in Rimkus, “courts in FSIA
    litigation have adopted a middle-ground approach that permits courts in subsequent related cases
    to rely on the evidence presented in earlier litigation—without necessitating the formality of
    having that evidence reproduced—to reach their own, independent findings of fact in the cases
    before them.” Id. “This is permissible because the validity of judicial records is generally ‘not
    subject to reasonable dispute,’ and such records are perfectly capable of establishing the type and
    substance of evidence that was presented to earlier courts.” Id. (citing Fed. R. Evid. 201(b)). The
    Court agrees, and so will make its own findings of fact while relying on evidence presented in
    earlier, but related, cases. See Encinas, supra, at 4–5.
    B.      Findings of Fact
    Based on the evidence presented to the Court and the testimonial evidence in the Sotloff
    proceedings, the Court makes the following findings of fact.
    1.      The Rise of ISIS
    “Syria has provided safe haven and support to terrorist organizations within its borders for
    decades.” Sotloff, 525 F. Supp. 3d at 127. One such group is the Zarqawi organization, a militant
    group that originated in the 1990s and—after several name changes—evolved into what we now
    know as the “Islamic State of Iraq and al-Sham,” or “ISIS.” Gartenstein-Ross Report at 13. This
    section includes the Court’s findings regarding the history of the Zarqawi organization and its ties
    5
    to the Syrian government, relying primarily on the expert report of Dr. Gartenstein-Ross. See id.
    at 13–23, 44–73.
    The namesake of the Zarqawi organization is “Ahmed Fadil al-Nazal al-Khalayleh, better
    known as Abu Musab al-Zarqawi.”         Id. at 13.   As a young man, al-Zarqawi “joined the
    transnational jihadist movement” and trained for combat at a camp in Afghanistan run by al-Qaeda
    leader Osama bin Laden. Id. at 14. Al-Zarqawi “built relationships with other jihadists in
    Afghanistan that allowed him to form the ‘Zarqawi organization.’” Id.
    The Zarqawi organization began coordinating with al-Qaeda in the early 2000s. See id. at
    15–16. In October 2004, al-Zarqawi pledged an oath of allegiance to bin Laden, at which point
    his organization became between known as al-Qaeda in Iraq or “AQI.” Id. at 17.
    The Zarqawi organization soon began coordinating with other jihadist and insurgent
    groups. “On January 15, 2006, AQI’s deputy emir, Abu Maysarah al-Iraqi, announced the
    establishment of the . . . Mujahedin Shura Council, or MSC. . . , an umbrella group composed of
    six Iraqi Sunni militant factions.” Id. at 17. “The main thing MSC accomplished, in addition to
    providing a cover for AQI, was formalizing longstanding alliances between AQI and lesser-known
    insurgent groups.” Id. at 18. The establishment of ISIS “can be understood as a continuation of
    this strategy of rebranding and expansion in an effort to gain greater support and legitimacy not
    only within the Iraqi insurgent landscape but also the global Muslim community.” Id. Al-Zarqawi
    died in June 2006, shortly after the creation of MSC. Id.
    MSC then rebranded as the Islamic State of Iraq, or “ISI,” in October 2006. Id. at 18. ISI
    “immediately set out to build a scalable bureaucratic framework that would eventually define the
    Islamic State during the Syrian civil war.” Id. at 18–19 (quotation omitted). For example, ISI
    named a cabinet, executed “small-scale public works projects,” called for emigration of their
    6
    “Muslim brothers,” recruited members with administrative and scientific backgrounds, and created
    an internal political-and-military bureaucracy. See id. at 19.
    ISI faced significant setbacks between 2006 and 2010, but the group had a resurgence after
    the selection of Abu Bakr al-Baghdadi 1 as its new emir in May 2010. Id. at 19–20. Al-Baghdadi
    first came into contact with earlier iterations of ISI in January 2006 when his former organization
    joined MSC. Id. at 17. “As unrest in Syria mounted in 2011,” al-Baghdadi “began laying the
    groundwork for ISI’s western expansion.” Id. at 21. In mid-2013, al-Baghdadi announced the
    formal merger between ISI and a Syria-based group called Jabhat al-Nusra. Id. at 22. This new
    entity was soon renamed the Islamic State of Iraq and al-Sham or “ISIS.” Id.
    ISIS’s control and influence continued to grow. In January 2014, ISIS took control of the
    Syrian city of Raqqa. Id. at 23. And in June of the same year, ISIS seized the Iraqi cities of Mosul
    and Tikrit. Id. ISIS “achieved global notoriety by the summer of 2014 for its battlefield victories
    and wanton brutality, which managed to shock people even in the midst of the world’s bloodiest
    civil war.” Id. It “managed to establish branches, or persuade other militant groups to declare
    their allegiance to it, in Afghanistan, Algeria, Bangladesh, Egypt, Libya, Nigeria, the Philippines,
    Somalia, and Yemen.” Id.
    “One factor that helped propel ISIS’s growth was its powerful propaganda machine, which
    can arguably be described as unprecedented for a violent non-state actor.” Id. ISIS “spread horrific
    imagery throughout the globe” using “the power of social media and significant advances in DIY
    video production.” Id. And ISIS “was particularly sadistic in its treatment of people unlucky
    enough to be captured by the militant group, including . . . journalists.” Id.
    1
    Al-Baghdadi later became the Caliph, or leader, of ISIS and took Kayla Mueller as his slave.
    Gartenstein-Ross Report at 17, 40–44.

    2.      Syria’s Relationship with ISIS Before the Arab Spring
    Well-documented and credible evidence establishes that, starting as early as 2002, Syria
    directly and indirectly supported the Zarqawi organization and its many iterations—both before
    and after the “Arab Spring” protests that “destabilized the region in 2011.” Id. at 3, 44, 55; see
    also Colvin v. Syrian Arab Republic, 
    363 F. Supp. 3d 141
    , 147 (D.D.C. 2019) (explaining that in
    March 2011, “Syria began to experience the effects of the ‘Arab Spring’—a wave of protests
    sweeping through the Middle East and North Africa against authoritarian governments” (citations
    omitted)). After the United States invaded Iraq in 2003, the Syrian regime “felt threatened, and
    believed that its policies of supporting insurgent groups could help prevent a military intervention
    to topple it.” Gartenstein-Ross Report at 51. “Syria’s considerable support of AQI was intended
    to undermine coalition efforts in Iraq,” and the “desire to see the United States defeated in Iraq
    was articulated explicitly by Syrian officials.” 
    Id. at 44
    .
    “Syria’s role as the primary transit point for militants heading to Iraq, as well as a
    permissive operating environment for Zarqawi network operatives stationed there, has been
    outlined and verified by insider accounts, official U.S. government statements, captured
    documents and data, and contemporaneous open-source reporting.” 
    Id. at 44
    . For example, in
    March 2003, “U.S. Secretary of Defense Donald Rumsfeld . . . ‘accused Syria of allowing military
    supplies to be transported across its border to Iraq.’” 
    Id. at 45
     (quoting Neil MacFarquhar, “A
    Nation at War: Damascus; Syria Wants U.S. To Lose War, Its Foreign Minister Declares,” New
    York Times, March 31, 2003, https://www.nytimes.com/2003/03/31/world/nation-war-damascus-
    syria-wants-us-lose-war-its-foreign-minister-declares.html).      Additionally, a March 2007
    Department of Defense report found that “Syria continues to provide safe haven, border transit,
    and limited logistical support to some Iraqi insurgents . . . [and] permits former regime elements
    to engage in organizational activities.” 
    Id. at 47
     (quoting Department of Defense, Measuring
    8
    Stability and Security in Iraq (March 2007), p. 17). And a 2014 report from the U.S. Department
    of State concluded that “Syria had served as a ‘key hub’ for foreign fighters travelling to Iraq” and
    explained that “those very networks were the seedbed for the violent extremist elements that
    terrorized the Syrian population in 2013.” 
    Id. at 48
     (quoting U.S. Department of State, Country
    Reports           on            Terrorism            2013            (2014),           https://2009-
    2017.state.gov/documents/organization/225050.pdf).
    Likewise, substantial evidence demonstrates that Syria provided training, weapons, and
    money to insurgents headed to Iraq. Defector Nawaf Fares reported that Assad’s brother-in-law,
    Assif Shawkat, ran an al-Qaeda training camp on the border with Iraq. See 
    id. at 53
    . Shawkat was
    named a Specially Designated National by the U.S. Treasury in 2006; at the time of his designation,
    Shawkat was the director of Syrian military intelligence. 
    Id. at 54
    . Additionally, “in December
    2009 Iraqi minister of defense Abd al-Qadir al-Ubaydi stated that ‘most of the weapons seized by
    his ministry’s forces’ were arriving from Syria, and the regime was ‘financing armed groups in
    Iraq.’” 
    Id.
     (quoting Al-Sharqiyah television (Arabic), December 12, 2009).
    It is therefore unsurprising that U.S. courts have repeatedly held Syria responsible for
    providing material support to ISIS and the previous iterations of the Zarqawi organization. See,
    e.g., Foley v. Syrian Arab Republic, 
    249 F. Supp. 3d 186
    , 193–95 (D.D.C. 2017) (concluding that
    Syria was responsible for the Zarqawi organization’s 2002 assassination of a U.S. diplomat in
    Amman Jordan, and the 2004 and 2006 abductions, torture, and executions of two U.S. service
    members near Baghdad, Iraq).
    3.      Syria’s Relationship with ISIS During and After the Arab Spring
    During and after the Arab Spring, the same fear of foreign military intervention that drove
    Assad to support the insurgency in Iraq led him to “provide [] both tacit and explicit support for
    ISIS, even though ISIS was actively fighting the [Syrian] regime.” Gartenstein-Ross Report at 55.
    9
    Assad wanted to “make anti-Assad elements appear as extreme, and hence unpalatable, as possible
    to the outside world” to stave off foreign intervention. Id. at 55; see also Sotloff, 525 F. Supp. 3d
    at 129 (“[F]earing Western military intervention of the sort that toppled Muammar al-Qaddafi in
    Libya, Syria’s President Bashar al-Assad began supporting the latest iteration of the Zarqawi
    organization in an effort to paint all of the Syrian opposition as terrorists, and thus make similar
    action to dislodge his regime harder.”       (quotations omitted)).     And the “mechanisms for
    maintaining a relationship with ISIS were well established due to the Assad regime’s previous
    support for the Zarqawi organization.” Gartenstein-Ross Report at 55. In this time period, Syria’s
    support of ISIS similarly took several forms, including the systematic release of jihadist prisoners,
    the purchase of oil and wheat from ISIS, and granting ISIS access to the international banking
    system.
    Syria’s release of 1,500 jihadist prisoners was deliberate and related to its fear of foreign
    intervention. “In 2011, Assad began releasing inmates en masse from Sednaya prison, one of
    Syria’s most notorious and brutal jails.” Id. at 56. Sednaya Prison was “home to many of the
    ‘battle-hardened Syrian jihadis’ who returned to Syria from the war in Iraq in the early 2000s, and
    was thus widely regarded an ‘incubator for jihadism.’” Id. (quoting Rania Abouzeid, “The Jihad
    Next Door: The Syrian Roots of Iraq’s Newest Civil War,” Politico, June 23, 2014,
    https://www.politico.com/magazine/story/2014/06/al-qaeda-iraq-syria-108214;         Roy     Gutman,
    “Assad Henchman: Here’s How We Built ISIS,” The Daily Beast, December 1, 2016,
    https://www.thedailybeast.com/assad-henchman-heres-how-we-built-isis). Assad released these
    prisoners while “protests against his regime were mounting,” and “part of the reason for the
    releases was to strengthen violent extremists.” Id.; see also U.S. Department of State, Interview,
    “John Kerry Interview With Gregory Palkot of Fox News,” November 17, 2015, https://2009-
    10
    2017.state.gov/secretary/remarks/2015/11/249588.htm (Secretary of State John Kerry describing
    ISIS as, in part, “created by Assad releasing 1,500 prisoners from jail” in order to create a binary
    choice between Assad and the terrorists); Levitt Report at 10 (describing a report from a former
    member of Syria’s Military Intelligence Directorate that the Syrian regime knew what would result
    from releasing the terrorist inmates from Sednaya).          “[T]he ability of jihadist groups to
    immediately capitalize on these releases was fundamentally rooted in Syria’s historical
    relationship with AQI.” Gartenstein-Ross Report at 63.
    Some of the released prisoners later became notable leaders in ISIS. For example, Ali al-
    Shawaq, also known as Abu Luqman, served as the governor of Raqqa for ISIS. Id. at 57–58.
    Luqman brought “hundreds of battle-hardened Nusra fighters with him to ISIS” and used his
    connections to recruit many more members into ISIS’s ranks. Id. at 58. He was also responsible
    for helping to entrench ISIS’s security state and, at the time of his death in 2018, he was Abu Bakr
    al-Baghdadi’s second in command. Id. at 59.
    Another released prisoner was Fiwaz Muhammad al-Kurdi al-Hiju. Al-Hiju was a friend
    of Abu Luqman from Sednaya prison and brough Luqman into ISIS. Id. at 57, 59. Al-Hiju was
    later appointed as ISIS’s first judge in mid-2013. Id. at 60. He “had the largest record of the death
    sentences for dissidents and civilians.” Id. (quotation omitted).
    Amr al Absi was also released from Sednaya in 2011. Id. at 61. After his release, he
    became a member of the MSC. Id. When the MSC’s leader fell, al Absi assumed control of the
    MSC and eventually steered the organization to become part of ISIS. Id. He was an important
    recruiter for ISIS and eventually ISIS’s governor of Aleppo. Al Absi was famous for his “zealous
    use of torture and imprisonment” and was directly involved in the torture and execution of Western
    11
    hostages. Id. at 62–63. And al Absi was also the leader of ISIS’s media wing and “was responsible
    for disseminating propaganda, including ISIS’s infamous beheading videos.” Id. at 63.
    Syria also purchased oil from ISIS; this support was “a particularly important source of
    revenue for ISIS.” Id. at 65. “In 2014, ISIS made between $150 million to $450 million from oil.”
    Id. at 66. Much of these sales were done through middlemen on the black market, but there is
    evidence that the Assad regime purchased oil directly from ISIS. See id. at 67–70; accord Levitt
    Report at 11–14. There is also evidence that the brokers of the Assad-ISIS trade relationship
    included Hussam al-Katerji, “a powerful figure in Assad’s regime” and an Aleppo parliamentarian.
    Gartenstein-Ross Report at 72. Syria thus had a direct financial relationship with ISIS—making
    it unique among purchasers of ISIS oil. Id. at 69–70; see also Kelly Hr’g Tr. Day 1 54:12–15
    (“According to numerous accounts, including documents intercepted from ISIS’s oil minister,
    Syria was the biggest consumer of ISIS’s oil . . . .”).
    Syria’s purchase of ISIS oil is particularly relevant here. As discussed below, it was Abu
    Sayyaf, an ISIS “oil tycoon,” who took custody of Kayla in September of 2014, Gartenstein-Ross
    Report at 71, and used her as his sex slave during the last several months of her captivity. See
    infra at 15–16. At that same time, Sayyaf’s division reported $40.7 million in revenue from
    October 25, 2014, to November 23, 2014. Gartenstein-Ross Report at 71. More generally, ISIS
    used its “massive oil revenue” to “undertake all the functions of its state,” including “to pay for its
    fighters, . . . to make military advances, . . . to keep its jails operating and to pay its jailors, . . . to
    transport prisoners around the country, . . . [and] to fund its media operations.” See Kelly Hr’g Tr.
    Day 1 83:22–84:5.
    Syria also purchased ISIS wheat and allowed banks in ISIS-controlled areas to continue to
    operate, giving ISIS access to international financial system that it otherwise would have been
    12
    blocked from. “The Financial Action Task Force (FATF), an inter-governmental policymaking
    body of which the United States is a member, issued a report that found that as of February 2015,
    Syria permitted more than 20 Syrian financial institutions to operate in ISIS-controlled territory.”
    Sotloff, 525 F. Supp. 3d at 129–30; accord Levitt Report at 14. “By allowing ISIS to use its banks,
    Syria provided vital access to the international financial system to ISIS, . . . that allowed it to
    ‘function as a local economy,’ i.e., to ‘send [money] abroad for purchasing power,’ to buy
    weapons, resources needed to keep the oil industry functioning, and ‘things [needed] to run society,
    the schools and garbage collection and everything else that a militant organization has to take care
    of when they take over control of territory.’” Sotloff, 525 F. Supp. 3d at 130 (quoting Kelly Hr’g
    Tr. Day 2 269:10–15, 273:23–274:5).
    Consistent with the foregoing evidence, the State Department identified Syria’s support for
    ISIS in its annual Country Reports on Terrorism from 2014 through 2017. See Exhibits 3–6, ECF
    Nos. 28-3–10; Sotloff, 525 F. Supp. 3d at 130–31.
    4.      ISIS’s Capture, Torture, and Execution of American Citizens
    Torture of ISIS detainees “typically beg[an] immediately upon the start of captivity[] and
    last[ed] until execution.”   Gartenstein-Ross Report at 26.       ISIS’s torture methods included
    interrogations, psychological torture—including “death threats, solitary confinement, being forced
    to watch the physical torture and execution of others, threats that the captives would face a similar
    fate, and mock executions”—and physical torture. Id. at 26–30 (citing Asaad Almohammad, Anne
    Speckhard & Ahmet S. Yayla, The ISIS Prison System: Its Structure, Departmental Affiliations,
    Processes, Conditions, and Practices of Psychological and Physical Torture (International Center
    for the Study of Violent Extremism Research Report, August 2017), https://www.icsve.org/the-
    isis-prison-system-its-structure-departmental-affiliations-processes-conditions-and-practices-of-
    13
    psychological-and-physical-torture/ (report based on interviews with 55 defectors and 17 civilians
    who had been captured and tortured by ISIS)).
    Female captives faced another routine form of torture—sex slavery. Id. at 30. “ISIS also
    frequently coerced female hostages into converting to the Islamic faith[] and forced them into
    ‘marriages’ with ISIS operatives.” Id. “ISIS believed that taking female slaves was religiously
    legitimate,” and ISIS’s internal documents reveal that the group believed that “the captivity and
    enslavement of the women of the disbelievers . . . are among the greatest forms of the honour of
    Islam and its Sharia.” Id. at 30–31 (quoting Aymenn Jawad al-Tamimi, “Unseen Islamic State
    Pamphlet         on         Slavery,”         Pundicity,         December          29,         2015,
    http://www.aymennjawad.org/2015/12/unseen-islamic-state-pamphlet-on-slavery).
    American hostages faced “particularly harsh treatment” by ISIS. Id. at 36. “ISIS’s
    treatment of its foreign hostages was partially contingent on whether a hostage’s government
    would be willing to pay ransom for his or her release.” Id. Britain’s and the U.S.’s policies against
    negotiating with terrorists “meant that American and British hostages were among the worst
    treated of all [ISIS] captives,” and is consistent with the lowest and second-lowest hostage release
    rates. Id.
    5.     ISIS’s Capture, Torture, and Execution of Kayla Mueller
    Kayla Jean Mueller was a U.S. citizen who “traveled to the Middle East shortly after the
    Syrian civil war broke out to help established aid organizations provide assistance to Syrian
    refugees.” Id. at 23. She was kidnapped at gunpoint by masked ISIS soldiers on August 4, 2013,
    while travelling in northern Syria with a Syrian colleague contracting for Doctors Without Borders.
    Ex. 24, ECF No. 28-28, at ¶ 7 (Affidavit of Special Agent William H. Heaney); Gartenstein-Ross
    Report at 23–24. During the first six months of her captivity, she was primarily held in isolation.
    See Gartenstein-Ross Report at 37–38 (citing James Gordon Meek et al., “Kayla Mueller in
    14
    Captivity: Courage, Selflessness as She Defended Christian Faith to ISIS Executioner ‘Jihadi
    John,’” ABC News, August 25, 2016, https://abcnews.go.com/International/kayla-mueller-
    captivity-courage-selflessness-defended-christian-faith/story?id=41626763).     She was moved
    several times to different temporary holding locations in Syria, id. at 38, including the prison in
    the basement of the Aleppo Eye Hospital where Nicholas Henin, James Foley, and Steven Sotloff
    were also held. Ex. 11R, ECF No. 28-16, at ¶ 26 (Declaration of Nicholas Henin). These three
    men heard Kayla beg her captors not to hurt her. Id. All four were later moved to Raqqa, and
    Kayla was brought to the cell shared by Henin, Foley, and Sotloff to provide a proof of life for
    Henin before he was released. Id. at ¶¶ 27–29. 2 While in Raqqa, Kayla was held in a small, hot
    cell with other prisoners and given very little to eat. Gartenstein-Ross Report at 39–40. Kayla
    was also taunted for being a Christian and “her jailers may have tried to coercively convert her.”
    Id. at 39.
    ISIS began to reach out to Kayla’s parents by email in May 2014. Ex. 28R, ECF No. 28-
    32, at 2–12. ISIS repeatedly demanded the release of Dr. Afia Siddiqi, a U.S. prisoner convicted
    of the attempted murder of U.S. officers and employees, or £5 million in cash. Id. at 3, 7. ISIS
    threatened to kill Kayla unless its demands were met. Id. at 4, 9.
    In September 2014, Kayla and two kidnapped Kurdish women of Yazidi Heritage were
    transferred from an ISIS prison to the custody of Umm Sayyaf and her husband, Abu Sayyaf. Ex.
    24 at ¶¶7–9. As noted above, Abu Sayyaf was ISIS’s minister for oil and gas; he reported directly
    to ISIS’s leader, Abu Bakr al-Baghdadi. Id. ¶ 9. According to statements made by Umm Sayyaf
    to the FBI, Kayla and her co-captives were handcuffed, locked in their rooms, and deprived of
    2
    ISIS released Henin in April 2014. Ex. 11 at ¶ 7. Foley and Sotloff were beheaded by ISIS in
    the early fall of 2014. Gartenstein-Ross Report at 39–40.
    15
    their freedom in the Sayyaf residence. Id. ¶ 10. They were threatened with death for disobedience
    and shown violent ISIS propaganda videos. Id. ¶ 10, 12. The captive women were also considered
    to be “owned” by the ISIS men who “acquired” them. Id. ¶ 10.
    Abu Bakr al-Baghdadi “owned” Kayla during her captivity at the Sayyaf residence. Id.
    ¶18. “While in captivity, Kayla Jean Mueller was sexually abused by Baghdadi, who forced her
    to have sex with him.” Id. ¶10; accord Gartenstein-Ross Report at 24 (“Around September 2014,
    Abu Bakr al-Baghdadi took Mueller as one of his sex slaves, and, until her death on or before
    February 6, 2015, held her prisoner in the homes of several ISIS leaders, including his own.”).
    ISIS reported Kayla’s death in February 2015. Gartenstein-Ross Report at 24. ISIS
    claimed at that time that Kayla was killed in a Jordanian airstrike. Id. But credible statements
    from ISIS insiders—two women involved in Kayla’s captivity—demonstrate that it is more likely
    that Kayla was executed by ISIS. See id. at 24–25.
    In particular, Umm Sayyaf told the FBI that “Baghdadi and ISIS spokesman Abu
    Muhammad al-Adnani ordered [Kayla] Mueller’s execution because she knew their identities and
    constituted a security risk.” Id. at 25. Umm Sayyaf told the FBI that she heard this information
    from her husband just a few weeks after Kayla’s death and she judged his statement to be credible.
    Id.
    Umm Sayyaf’s claim that ISIS executed Kayla is “bolstered by those of a former sex slave
    of a high-ranking ISIS leader, an unnamed Yazidi woman,” who reported to the BBC that she
    remembers that ISIS leader “laughing at the news reports that Kayla was killed in a coalition
    airstrike.” Id. The ISIS leader told the Yazidi woman that ISIS killed Kayla for revenge because
    she was an American. Id. at 25–26.
    16
    III.     Legal Standards
    Courts are permitted to enter default judgments against parties who fail to appear before
    them. Fed. R. Civ. P. 55(b)(2). But as noted above the “entry of a default judgment is not
    automatic.” Mwani v. bin Laden, 
    417 F.3d 1
    , 6 (D.C. Cir. 2005) (footnote omitted). The Court
    has the “affirmative obligation” to ensure that it has subject matter jurisdiction over the action and
    personal jurisdiction over the defendant. See Sotloff, 525 F. Supp. 3d at 133 (quotation omitted).
    Additionally, “[w]hen default judgment is sought under the FSIA, a claimant must
    ‘establish[] his claim or right to relief by evidence satisfactory to the court.’” Warmbier v.
    Democratic People’s Republic of Korea, 
    356 F. Supp. 3d 30
    , 42 (D.D.C. 2018) (quoting 
    28 U.S.C. § 1608
    (e)). Because “Congress enacted the terrorism exception expressly to bring state sponsors
    of terrorism . . . to account for their repressive practices,” Han Kim v. Democratic People’s
    Republic of Korea, 
    774 F.3d 1044
    , 1048 (D.C. Cir. 2014), and the Court of Appeals has instructed
    that “courts have the authority—indeed . . . the obligation—to adjust evidentiary requirements to
    . . . differing situations,” 
    id.
     (quotation omitted), the standard of proof in FSIA default judgment
    actions is more lenient.
    Therefore, “[i]n a FSIA default proceeding, a court can find that the evidence presented is
    satisfactory “when the plaintiff shows ‘her claim has some factual basis,’ . . . even if she might not
    have prevailed in a contested proceeding.” Sotloff, 525 F. Supp. 3d at 134 (quoting Owens v.
    Republic of Sudan, 
    864 F.3d 751
    , 785 (D.C. Cir. 2017), vacated on other grounds, 
    140 S. Ct. 1601 (2020)
     (citations omitted)).     “[U]ncontroverted factual allegations supported by admissible
    evidence may be taken as true,” 
    id.,
     and § 1608(e) “does not require a court to step into the shoes
    of the defaulting party and pursue every possible evidentiary challenge.” Owens, 
    864 F.3d at 785
    .
    “And this discretion extends to the admission of expert testimony, often ‘of crucial importance in
    terrorism cases . . . because firsthand evidence of terrorist activities is difficult, if not impossible,
    17
    to obtain,’ ‘[v]ictims of terrorist attacks . . . are often . . . unable to testify about their experiences,’
    and ‘[p]erpetrators of terrorism typically lie beyond the reach of the courts and go to great lengths
    to avoid detection.’” Sotloff, 525 F. Supp. 3d at 134 (quoting Owens, 
    864 F.3d at 787
    ).
    IV.     Conclusions of Law
    Based on the above findings of fact, see Part II(B), the Court makes the following
    conclusions of law.
    A. The Court Has Jurisdiction Over This Action
    The Court is satisfied that it has subject matter, original, and personal jurisdiction over this
    action. Because both personal and original jurisdiction turn on whether this Court has subject
    matter jurisdiction, the Court begins there.
    1.       Subject Matter Jurisdiction
    The FSIA state-sponsored-terrorism exception provides federal courts with subject matter
    jurisdiction over cases “in which money damages are sought against a foreign state for personal
    injury or death that was caused by” certain acts of terrorism against U.S. nationals. 28 U.S.C.
    § 1605A(a)(1)–(2). The Muellers must prove four elements to establish that the Court has subject
    matter jurisdiction over this action: (1) Syria “was designated a state sponsor of terrorism when
    the act of terrorism occurred and when this action was filed;” (2) Kayla and the Muellers were
    U.S. nationals at the time of the acts of terrorism; (3) the Muellers afforded Syria a reasonable
    chance to arbitrate their claims; and (4) Syria’s actions qualify under the terrorism exception of
    the FSIA as defined in 28 U.S.C. § 1605A(a)(1). See Sotloff, 525 F. Supp. 3d at 134; 28 U.S.C.
    § 1605A(a)(1)–(2). The Muellers have proven all four elements.
    First, Syria was a designated state-sponsor of terrorism at all relevant times. The United
    States first designated Syria as a state-sponsor of terrorism in 1979 and has continued to designate
    Syria as a state-sponsor of terrorism since, including during the time of the acts of terrorism against
    18
    Kayla and when they filed this suit. See State Sponsors of Terrorism, U.S. Dep’t of State,
    https://www.state.gov/state-sponsors-of-terrorism/ (explaining that Syria was designated as a state
    sponsor of terrorism in 1979 and continues to be so designated).
    Second, all of the Muellers were United States citizens at the relevant times, see Ex. 12,
    ECF No. 28-17 (Affidavit of Marsha Jean Mueller), and thus were U.S. nationals within the
    meaning of the FSIA. 28 U.S.C. § 1605A(h)(5); 
    8 U.S.C. § 1101
    (a)(22).
    Third, the Muellers offered to arbitrate their claims against Syria. “The FSIA does not
    require any particular form of offer to arbitrate, simply the extension of a reasonable opportunity.”
    Sotloff, 525 F. Supp. 3d at 135 (quotations omitted). The Muellers sent an offer to arbitrate, a
    translation of that letter in Arabic, and a copy and translation of the complaint to the Syrian
    Ministry of Foreign Affairs. See Ex. 14, ECF No. 28-18, at ¶ 5 (Affidavit of Emily Amick). These
    actions fulfilled the Muellers’ duty to extend a “reasonable opportunity” to Syria to arbitrate.
    Finally, Syria’s actions qualify under the terrorism exception of the FSIA. See 28 U.S.C.
    § 1605A(a)(1). “The fourth element of subject-matter jurisdiction under the FSIA terrorism
    exception is that the plaintiffs seek [money] damages for personal injury or death caused by the
    foreign state’s commission of at least one terrorist act enumerated in the statute, including ‘torture,
    extrajudicial killing, aircraft sabotage, hostage taking, or the provision of material support or
    resources for such an act.’” Sotloff, 525 F. Supp. 3d at 135 (quoting 28 U.S.C. § 1605A(a)(1)).
    Because the Muellers seek money damages, see 28 U.S.C. § 1605A(c) (“[Money] damages may
    include economic damages, solatium, pain and suffering, and punitive damages.”), and because
    they have demonstrated that Kayla suffered hostage taking, torture, and extrajudicial killing at the
    hands of ISIS and that Syria caused these injuries by providing material support and resources to
    ISIS, the Muellers have carried their burden.
    19
    a.     Hostage Taking
    The FSIA defines “hostage taking” by reference to Article 1 of the International
    Convention against the Taking of Hostages, which states:
    Any person who seizes or detains and threatens to kill, to injure, or to continue to
    detain another person . . . in order to compel a third party . . . to do or abstain from
    doing any act as an explicit or implicit condition for the release of the hostage
    commits the offense of taking of hostages.
    28 U.S.C. § 1605A(h)(2); International Convention Against the Taking of Hostages art. 1, Dec.
    17, 1979, 18 I.L.M. 1456, 1316 U.N.T.S. 205. Hostage taking has two elements: (1) the abduction
    or detention and (2) the purpose of accomplishing the third-party compulsion described in the
    definition provided by the Convention. See Sotloff, 525 F. Supp. 3d at 135.
    The Mueller have satisfied both elements. The evidence submitted by the Muellers—
    including the Gartenstein-Ross report, the emails between ISIS and Carl Mueller, the statements
    of Umm Sayyaf to the FBI, the declaration of Nicholas Henin, and the testimony of the Yazidi
    woman—shows that Kayla was abducted by ISIS and held in captivity until her death. See supra
    at 14–16. And the emails between ISIS and Carl Mueller show that the purpose of Kayla’s
    captivity and detention was to try to extract either a prisoner exchange between the U.S. and ISIS
    or £5 million from the Muellers. See generally Ex. 28R. In addition, as Dr. Gartenstein-Ross put
    it, “ISIS took hostages and treated them so brutally for the broader purpose of ‘send[ing] [a]
    message and . . . giv[ing] it complete control over populations and prisoners who fell under its
    control.’” Sotloff, 525 F. Supp. 3d at 136 (quoting Kelly Hr’g Tr. Day 1 92:22–93:2).
    b.     Torture
    The FSIA defines “torture” by reference to the Torture Victim Protection Act (“TVPA”).
    28 U.S.C. § 1605A(h)(7). Under that statute,
    20
    (1) the term “torture” means any act, directed against an individual in the offender’s
    custody or physical control, by which severe pain or suffering (other than pain
    or suffering arising only from or inherent in, or incidental to, lawful sanctions),
    whether physical or mental, is intentionally inflicted on that individual for such
    purposes as obtaining from that individual or a third person information or a
    confession, punishing that individual for an act that individual or a third person
    has committed or is suspected of having committed, intimidating or coercing
    that individual or a third person, or for any reason based on discrimination of
    any kind; and
    (2) mental pain or suffering refers to prolonged mental harm caused by or resulting
    from—
    (A) the intentional infliction or threatened infliction of severe physical pain
    or suffering;
    (B) the administration or application, or threatened administration or
    application, of mind altering substances or other procedures calculated to
    disrupt profoundly the senses or the personality;
    (C) the threat of imminent death; or
    (D) the threat that another individual will imminently be subjected to death,
    severe physical pain or suffering, or the administration or application of
    mind altering substances or other procedures calculated to disrupt
    profoundly the senses or personality.
    Torture Victim Protection Act of 1991 § 3(b), 
    Pub. L. No. 102-256, 106
     Stat. 73 (1992), codified
    at 
    28 U.S.C. § 1350
     (note). “To establish torture, the plaintiffs must also show that the conduct
    was sufficiently severe and purposeful.” Sotloff, 525 F. Supp. 3d at 137.
    The Muellers have certainly established that Kayla was tortured by ISIS. As an initial
    matter, as Dr. Gartenstein-Ross testified, “[n]obody who escaped from ISIS’s imprisonment has
    ever reported not being tortured.” Kelly Hr’g Tr. Day 1 93:12–13. Credible evidence establishes
    that Kayla was subjected to prolonged periods of solitary confinement, Gartenstein-Ross Report
    at 37–38, miserable living conditions, see id. at 39–40, death threats, Ex. 24 at ¶12, and sexual
    abuse, id. ¶10; accord Gartenstein-Ross Report at 24. And credible evidence establishes that Kayla
    was subjected to these different forms of mistreatment because she was American and, sometimes,
    21
    because she was a Christian. Gartenstein-Ross Report at 25–26, 39. This evidence is more than
    enough to show that ISIS tortured Kayla at such a severe level and with sufficient purpose to meet
    the definition outlined in the TVPA.
    c.      Extrajudicial Killing
    “The state-sponsored terrorism exception to the FSIA also defines ‘extrajudicial killing’
    through reference to the TVPA.” Sotloff, 525 F. Supp. 3d at 137 (citing 28 U.S.C. § 1605A(h)(7)).
    The TVPA defines extrajudicial killing as
    a deliberated killing not authorized by a previous judgment pronounced by a
    regularly constituted court affording all the judicial guarantees which are
    recognized as indispensable by civilized peoples. Such term, however, does not
    include any such killing that, under international law, is lawfully carried out under
    the authority of a foreign nation.
    TVPA § 3(a). This definition “contains three elements: (1) a killing; (2) that is deliberated; and
    (3) is not authorized by a previous judgment pronounced by a regularly constituted court.” Owens,
    
    864 F.3d at 770
    .
    Although there is some evidence to the contrary, the evidence shows that ISIS deliberately
    killed Kayla because she was a security threat to ISIS. See supra at 15–16. The Court concludes
    that the statements of Umm Sayyaf and the Yazidi woman that Kayla was intentionally killed by
    ISIS for this reason are more credible than the statements of ISIS that she died in an airstrike. See
    id.
    d.      Material Support and Causation
    “The final requirement under § 1605 is a showing that [Kayla Mueller’s] abduction, torture,
    and [execution] were ‘caused by. . . the provision of material support or resources’ to ISIS by ‘an
    official, employee, or agent’ of Syria.” Sotloff, 525 F. Supp. 3d at 138 (quoting 28 U.S.C.
    § 1605A(a)(1)). The FSIA defines “material support” by way of 18 U.S.C. § 2339A:
    22
    any property, tangible or intangible, or service, including currency or monetary
    instruments or financial securities, financial services, lodging, training, expert
    advice or assistance, safehouses, false documentation or identification,
    communications equipment, facilities, weapons, lethal substances, explosives,
    personnel (1 or more individuals who may be or include oneself), and
    transportation, except medicine or religious materials.
    18 U.S.C. § 2339A(b)(1); see also 
    28 U.S.C. § 1605
    (h)(3). The FSIA only requires a plaintiff to
    show proximate cause. Kilburn v. Socialist People’s Libyan Arab Jamahiriya, 
    376 F.3d 1123
    ,
    1128 (D.C. Cir. 2004). The Muellers can establish proximate cause by showing “a reasonable
    connection between the material support provided and the ultimate act of terrorism.” Foley, 
    249 F. Supp. 3d at 204
     (quotation omitted). “More specifically, [the Muellers] must establish (1) that
    Syria’s provision of material support was a ‘substantial factor in the sequence of events’ that led
    to [Kayla’s] hostage taking, torture, and extrajudicial killing, and (2) that what happened to [Kayla]
    was ‘reasonably foreseeable or anticipated as a natural consequence of [Syria’s] conduct.’” See
    Sotloff, 525 F. Supp. 3d at 139 (quoting Owens 
    864 F.3d at 794
    ).
    To begin, the evidence establishes that Syria provided material support to ISIS. Based on
    the findings of fact above, the Court concludes that Syria provided ISIS material support through
    the release of prisoners and through financial assistance in the form of oil purchases, wheat
    purchases, and access to the international financial system. See supra at Part II(B)(3); see also
    Sotloff, 525 F. Supp. 3d at 138–39. Syria also provided material support to ISIS’s precursors by
    operating as a primary transit point for jihadist fighters, as well as training, weapons, and money
    to insurgents headed to Iraq. See supra at Part II(B)(2). These actions constitute material support
    in the form of “currency or monetary instruments or financial securities,” “financial services,”
    “training, expert advice or assistance,” “weapons,” and “transportation.”            See 18 U.S.C.
    § 2339A(b)(1).
    23
    Second, the Court concludes that Syria’s aid to ISIS was at least a substantial factor in the
    sequence of events that led to Kayla’s hostage taking, torture, and extrajudicial killing. Syria’s
    “mechanisms for maintaining a relationship with ISIS were well established” by the time of the
    Arab Spring “due to the Assad regime’s previous support for the Zarqawi organization.”
    Gartenstein-Ross Report at 55. And Syria’s support of ISIS after the Arab Spring, and during the
    time of Kayla’s captivity and death, included the release of prisoners who became key leaders of
    ISIS and who were responsible for its growth and success, the provision of a significant proportion
    of ISIS’s financial resources, and the connection to the international banking system. Id. at 55–
    73.
    Finally, the actions of ISIS were reasonably foreseeable to Syria. As Dr. Levitt put it,
    “[t]here is no question—absolutely no question that the Assad regime knew; expected; wanted the
    Islamic State to engage in acts of abhorrent violence [such as those inflicted on Ms. Mueller]
    specifically so that it would become a worse boogeyman than the Syrian Regime.” Kelly Hr’g Tr.
    Day 2 291:22–292:1.
    The evidence therefore establishes that (1) Syria “was designated a state sponsor of
    terrorism when the act of terrorism occurred and when this action was filed;” (2) Kayla and the
    Muellers were U.S. nationals at the time of the acts of terrorism; (3) the Muellers afforded Syria a
    reasonable chance to arbitrate their claims; and (4) Syria’s actions qualify under the terrorism
    exception of the FSIA as defined in 28 U.S.C. § 1605A(a)(1), see Sotloff, 525 F. Supp. 3d at 134;
    28 U.S.C. § 1605A(a)(1)–(2). The Court has subject matter jurisdiction over this action.
    2.      Original Jurisdiction
    “Under 
    28 U.S.C. § 1330
    , federal district courts have original jurisdiction over FSIA claims
    that are (1) nonjury civil actions (2) for claims seeking relief in personam (3) against a foreign
    state (4) when the foreign state is not entitled to immunity under 
    28 U.S.C. §§ 1605
    , 1606, 1607,
    24
    or any applicable international agreement.” Encinas, supra, at 17 (citing 
    28 U.S.C. § 1330
    (a)).
    The Muellers have not sought a jury trial, see generally Compl.; the suit is brought against Syria
    in its capacity as a legal person, not against property; Syria is a foreign state; and Syria is not
    entitled to sovereign immunity because this action falls under the state-sponsored-terrorism
    exception in the FSIA. See supra Part IV(A)(1). The Court therefore has original jurisdiction over
    this action.
    3.     Personal Jurisdiction
    To impose judgment on a foreign state under the FSIA, the Court must also have personal
    jurisdiction. Sotloff, 525 F. Supp. 3d at 140. The Court has personal jurisdiction over Syria if it
    (1) has original jurisdiction under the FSIA; and (2) Syria was properly served under the FSIA.
    
    28 U.S.C. § 1330
    (b). Because the Muellers “have already satisfied the first requirement, the Court
    turns to the second.” Sotloff, 525 F. Supp. 3d at 140.
    The FSIA provides four methods of serving a foreign state, as well as the order in which
    plaintiffs must attempt them:
    (1) by delivery of a copy of the summons and complaint in accordance with any
    special arrangement for service between the plaintiff and the foreign state or
    political subdivision; or
    (2) if no special arrangement exists, by delivery of a copy of the summons and
    complaint in accordance with an applicable international convention on service of
    judicial documents; or
    (3) if service cannot be made under paragraphs (1) or (2), by sending a copy of the
    summons and complaint and a notice of suit, together with a translation of each into
    the official language of the foreign state, by any form of mail requiring a signed
    receipt, to be addressed and dispatched by the clerk of the court to the head of the
    ministry of foreign affairs of the foreign state concerned, or
    (4) if service cannot be made within 30 days under paragraph (3), by sending two
    copies of the summons and complaint and a notice of suit, together with a
    translation of each into the official language of the foreign state, by any form of
    mail requiring a signed receipt, to be addressed and dispatched by the clerk of the
    court to the Secretary of State in Washington, District of Columbia, to the attention
    25
    of the Director of Special Consular Services—and the Secretary shall transmit one
    copy of the papers through diplomatic channels to the foreign state and shall send
    to the clerk of the court a certified copy of the diplomatic note indicating when the
    papers were transmitted.
    
    28 U.S.C. § 1608
    (a). “Because Syria does not have a special arrangement for service with [the
    Muellers], nor is it a party to an international convention on service, [the Muellers] did not need
    to attempt service in accordance with § 1608(a)(1) or (a)(2).” See Sotloff, 525 F. Supp. 3d at 141.
    The Muellers attempted to serve Syria under § 1608(a)(3) in July 2018. See ECF Nos. 7, 11. When
    service failed, the Muellers served Syria under § 1608(a)(4) by diplomatic note forwarded by the
    State Department to the Foreign Interests Section of the Embassy of the Czech Republic in
    Damascus. See ECF No. 16. “Although Syria refused to accept delivery, service was still proper.”
    See Sotloff, 525 F. Supp. 3d at 141; see also ECF No. 16 at 5 (explaining that Syria refused to
    accept delivery).
    The Court therefore has personal jurisdiction over Syria under 
    28 U.S.C. § 1330
    (b).
    B.      The Court Needs Additional Briefing on Plaintiffs’ Tort Claims
    The FSIA creates a private right of action for victims of state-sponsored terrorism. 28
    U.S.C. § 1605A(c). “The right of action requires a demonstration (1) that [the] victim suffered an
    act of torture, extrajudicial killing, aircraft sabotage, hostage taking . . . ; (2) that the act was
    committed, or the provision [of material support or resources was] provided, by the foreign state
    or its agent; and that the act (3) caused (4) personal injury or death (5) for which the courts of the
    United States may maintain jurisdiction under this section for money damages.” Encinas, supra,
    at 19 (quotations omitted). “The third and fourth prongs require [the Muellers] to articulate a way
    to recover through the lens of civil-tort liability.” Id. at 20.
    “Having already concluded that the Court possesses subject-matter jurisdiction, little else
    is needed to show that Plaintiffs are entitled to relief.” See Sotloff, 525 F. Supp. 3d at 141 (citing
    26
    28 U.S.C. § 605A(c)). As explained above, the evidence establishes that Kayla was the victim of
    hostage taking, torture, and extrajudicial killing, see supra Part IV(A)(1)(a)–(c); that Syria
    provided material support to ISIS, see supra Part IV(A)(1)(d); and that the Court has jurisdiction.
    See supra Part IV(A).
    All that is left is whether the Muellers have satisfied the third and fourth elements—which,
    again, are evaluated “through the lens of civil-tort liability.” Encinas, supra, at 20. “The elements
    of causation and injury in the federal cause of action created by § 1605A require FSIA plaintiffs
    to prove a theory of liability which justifies holding the defendants culpable for the injuries that
    the plaintiffs allege to have suffered.” Fain, 
    856 F. Supp. 2d at 122
     (quotation omitted); accord
    Barry v. Islamic Republic of Iran, 
    410 F. Supp. 3d 161
    , 176 (D.D.C. 2019) (“[A]lthough section
    1605A creates a private right of action for claimants who meet its other requirements, a FSIA
    plaintiff must further ‘prove a theory of liability’ to establish a claim for relief that entitles them
    to damages.” (quoting Valore v. Islamic Republic of Iran, 
    700 F. Supp. 2d 52
    , 73 (D.D.C. 2010))
    (citation omitted)). “Based on the Circuit Court’s guidance, District Courts in this jurisdiction
    ‘rely on well-established principles of law, such as those found Restatement (Second) of Torts and
    other leading treatises, as well as those principles that have been adopted by the majority of state
    jurisdictions’ to outline the boundaries of these theories of recovery.” Encinas, supra, at 21–22
    (quoting In re Islamic Republic of Iran Terrorism Litig., 
    659 F. Supp. 2d 31
    , 61 (D.D.C. 2009)).
    The Complaint appears to include nine possible claims for relief: wrongful death, assault,
    battery, false imprisonment and kidnapping, intentional infliction of emotional distress including
    solatium, survival damages, conspiracy, aiding and abetting, and punitive damages. See generally
    Compl. Plaintiffs’ Motion, however, does not discuss the elements of those claims, which Plaintiff
    brings which claim, or how the evidence satisfies the elements of those claims. See generally Mot.
    27
    The Court therefore orders Plaintiffs to submit supplemental briefing that “articulate[s] the
    justification for such recovery . . . through the lens of civil tort liability.” See Rimkus, 750 F. Supp.
    2d at 176. For each claim alleged in the Complaint, the briefing should address its elements, the
    evidence that satisfies each element, and which Plaintiff can recover for that claim.
    V.      Conclusion
    The Muellers moved for default judgment as to liability only. See Mot. at 1. In order
    finally to decide the question of liability, the Court requires the additional briefing discussed
    above. Plaintiffs are therefore ORDERED to submit the additional briefing by March 1, 2023.
