    THE PEOPLE,                                                            A157230
    Plaintiff and Respondent,

    ZURI A. WILSON,                                                         Super. Ct. Nos. 13028170 /
    225664)
    Defendant and Appellant.
    After two assailants shot and killed a man outside a public housing
    project in San Francisco, Zuri A. Wilson was convicted of the murder (Pen.
    Code, § 187, subd. (a)) and sentenced to life in prison without parole. In this
    appeal, he contends that the trial court erred in denying his motion to
    suppress evidence because the police violated his Fourth Amendment rights
    when they conducted a search of his phone using a cell site simulator. He
    also asserts that the court erred in denying his motion for a mistrial after the
    prosecution withheld exculpatory evidence until the fifth week of trial, in
    violation of the prosecution’s obligations under Brady v. Maryland (1963) 
    373 U.S. 83
     (Brady). Although we reject Wilson’s Fourth Amendment claim, we
    agree that the prosecution violated his due process rights by failing to timely
    disclose key evidence. We therefore reverse.

    BACKGROUND
    The victim, Shawnte Otis, was killed as he was retrieving something
    from his rental car. His aunt, Demetria B., who was with him at the time,
    saw only one of the shooters: a light-skinned black male, 5’9” to 6’1” tall,
    wearing a red baseball cap, a black hoodie, black clothing, and a black mask.
    A surveillance camera recorded video of the shooting, but it was not clear
    enough to identify the faces of the shooters. Based on the physical evidence,
    police determined that the shooters were using a nine-millimeter pistol and a
    .45-caliber handgun with RWS brand ammunition.
    Shortly after the murder, police spoke with Yvette M., who lived on a
    street adjacent to the housing project. Just after hearing the shots, she saw
    two men run down the hill and get into a charcoal-colored Nissan that was
    parked directly in front of her vehicle, down the street from her house, and
    drive away. They were wearing jeans and hoodies, and one of the men had a
    black backpack.
    By reviewing surveillance video, police identified a gray Nissan Altima
    being driven by Wilson near the crime scene about two hours before the
    shooting. A female friend had rented the vehicle for a week at Wilson’s
    behest. In the video, shortly after Wilson drove past, the curtains and door
    closed in an abandoned apartment where the police believed the shooters
    waited before the homicide.
    Police obtained cell phone records for Wilson, which indicated that his
    cell phone had connected to cell towers within one-half to three-quarters of a
    mile from the housing project on the afternoon of the shooting and left the
    vicinity after the shooting.
    Police also conducted searches of several addresses they believed to be
    associated with Wilson. At an apartment on Montoya Street in San Pablo, in
    2
    the front closet, they found the nine-millimeter pistol used in the murder and
    a green backpack with binoculars and walkie-talkies, as well as clothing and
    other items. In a bedroom they found a black face mask, black beanie, other
    black clothing, a hard gun case, a soft rifle case, and metal letters
    purportedly spelling out Z-U-R-I. The apartment had beds in two separate
    rooms and more than one closet, and the police seized a lease, bills, and other
    documents reflecting the names of several individuals other than Wilson. In
    a subsequent search of the apartment, police found some .45-caliber RWS
    brand bullets.
    The police arrested Wilson, a light-skinned black male who is 5’7” tall.
    At trial, Wilson argued that the prosecution’s case was based entirely on
    circumstantial evidence that failed to establish that he was one of the
    shooters. There was no DNA or other physical evidence connecting him to
    the crime, and the police never identified the second shooter. Wilson asserted
    that he was a gun dealer and drug dealer and that his text messages showed
    that he was in the area to sell drugs that afternoon. He argued that Yvette
    M.’s account was unreliable given her testimony that she was an alcoholic
    who had been drinking that day.
    Although Wilson did not dispute that he sometimes stayed at the
    Montoya Street apartment, he pointed to evidence that other individuals had
    access to the apartment, including an associate of his named Vernon C.
    Further, DNA testing excluded Wilson as a source of DNA found on the nine-
    millimeter murder weapon and on the RWS ammunition. Instead, Vernon
    C.’s DNA was found on the murder weapon, and DNA for an unknown female
    was found on the RWS cartridges.

    DISCUSSION
    A.
    Wilson contends that the trial court erred in denying his motion to
    suppress evidence resulting from the police department’s use of a cell site
    simulator to locate his cell phone and, with it, the Montoya Street apartment.
    The People concede that the use of the cell site simulator was a search that
    required a warrant. (See, e.g., United States v. Ellis (N.D. Cal. 2017) 
    270 F.Supp.3d 1134
    , 1146 (Ellis).) However, they argue that the evidence should
    not be suppressed because the good faith exception to the exclusionary rule
    applies here. On de novo review, we agree and affirm the trial court’s denial.
    (See People v. Mateljan (2005) 
    129 Cal.App.4th 367
    , 373 [in reviewing denial
    of a motion to suppress, “ ‘ we give deference to the trial court’s factual
    determinations[,] [but] we independently decide the legal effect of such
    determinations ’ ”].)
    1.
    Under the Fourth Amendment to the United States Constitution, law
    enforcement authorities must obtain a judicial warrant before conducting a
    search or seizure unless an exception to the warrant requirement
    applies. (See, e.g., People v. Williams (1999) 
    20 Cal.4th 119
    , 125-126.) The
    warrant must “particularly describ[e] the place to be searched, and the
    persons or things to be seized.” (U.S. Const., 4th Amend.) When applicable,
    the exclusionary rule prohibits the use of evidence seized in violation of the
    Fourth Amendment. (People v. Pearl (2009) 
    172 Cal.App.4th 1280
    , 1292
    (Pearl).) When the police obtain evidence as a result of an unlawful seizure,
    suppression “is not an automatic consequence.” (Herring v. United
    States (2009) 
    555 U.S. 135
    , 137 (Herring).) Under the good faith exception to
    the exclusionary rule, “evidence will not be suppressed if the police officer
    4
    had an objectively reasonable belief the search or seizure was constitutionally
    permissible.” (Pearl, supra, 172 Cal.App.4th at p. 1292; see also United
    States v. Leon (1984) 
    468 U.S. 897
    , 922 (Leon) [recognizing exception to
    exclusionary rule for “evidence obtained [by the police] in objectively
    reasonable reliance on a subsequently invalidated search warrant”].) The
    burden is on the People to establish that the exception applies. (Pearl, supra,
    172 Cal.App.4th at p. 1293.)
    2.
    Here, the police obtained a search warrant directing the telephone
    company to provide “pen register” and “trap-and-trace” data associated with
    Wilson’s cell phone for thirty days. As explained in the affidavit supporting
    the warrant, “[a] ‘Pen Register’ allows a telephone utility to capture the
    telephone numbers dialed out by the Subject Telephone Number; a ‘Trap-and-
    Trace’ device allows a telephone utility to capture the telephone numbers of
    telephones that call the Subject Telephone Number.” The warrant directed
    the telephone company to provide specified information relating to Wilson’s
    telephone number: “Base Station (Cell Antennae) configuration data
    associated with the network access events of the Subject Telephone Number,
    including geographic location estimates, cell site locations, signal strength
    and directional bearing associated with the network access events for Subject
    Telephone Number, . . . via the facilities, technical equipment[] and software
    of the San Francisco Police Department.” The warrant also authorized
    “[g]eographic location estimates of the Subject Telephone Number device,
    derived from network signaling and cell site configuration information and
    analyzed via technical equipment and software of the San Francisco Police
    Department.” In addition, the warrant provided that “Peace Officers . . . are
    authorized to conduct remote monitoring of the Subject Telephone Number
    5
    device, day or night, including those signals produced in public, or locations
    not open to public or visual surveillance. If necessary, searching officers are
    authorized to employ the use of outside experts, acting under the direct
    control of investigating officers, to access and preserve any electronic data.”
    Although the warrant never mentioned the use of a cell site simulator,
    the police used one to identify the apartment building where Wilson was
    located. As its name suggests, a cell site simulator is a mobile device that
    locates nearby cell phones by simulating the telephone company’s cell tower,
    such that nearby cell phones transmit signals to the simulator rather than to
    the cell tower. (See, e.g., United States v. Lambis (S.D.N.Y. 2016) 
    197 F.Supp.3d 606
    , 609 (Lambis).) Here, the officer operating the cell site
    stimulator testified that information from the telephone company allowed the
    police to identify the general geographic area where Wilson’s phone was
    located, based on the location of the cell tower to which the phone was
    connecting. The officer then drove with the cell site simulator through that
    area “to try to find a signal for [Wilson’s] phone.” The device indicated when
    the officer was getting closer to Wilson’s phone and allowed him to determine
    that Wilson was likely located in a particular building.
    3.
    When the police used the cell site simulator to locate Wilson’s phone in
    October 2013, the state of the law on cell site simulators was less clear than
    it is today. The Supreme Court had considered another type of sense-
    enhancing technology in Kyllo v. United States (2001) 
    533 U.S. 27
    , which held
    that the use of a thermal imaging device to detect levels of heat within a
    private home constituted a search within the meaning of the Fourth
    Amendment. (Id., at p. 34.) Subsequently, United States v. Jones (2012) 
    565 U.S. 400
    , 404-405 (Jones), held that “the Government’s installation of a GPS
    6
    device on a target’s vehicle, and its use of that device to monitor the vehicle’s
    movements, constitutes a ‘search.’ ” (Ibid.; see also 
    ibid.
     [emphasizing the
    fact that in attaching the GPS device, “[t]he Government physically occupied
    private property for the purpose of obtaining information”]. The few cases
    specifically addressing the use of cell cite simulators resulted in differing
    opinions. (Compare In re Application of U.S. of Am. for an Order Authorizing
    Use of a Cellular Tel. Digital Analyzer (C.D. Cal. 1995) 885 F.Supp.197, 199-
    200 [“no court order is required to use a cellular telephone digital analyzer”];
    with In re Application of U.S. of Am. for an Order Authorizing the
    Installation & Use of a Pen Register & Trap & Trace Device (S.D. Tex. 2012)
    
    890 F.Supp.2d 747
    , 748 [denying application for order authorizing use of
    stingray as a pen register in the absence of authority that pen register
    statute, rather than warrant requirement, applies to stingrays, and noting
    that “there is scant case law addressing the equipment”]; see also Ellis,
    supra, 270 F. Supp. 3d at p. 1155 [stating that at the time cell site simulator
    in that case was used in January 2013, “there was no controlling authority as
    to whether its use constituted a search requiring issuance of a warrant”].)
    The United States Supreme Court did not consider the Fourth
    Amendment implications of cell site location information until 2018, in
    Carpenter v. United States (2018) 
    138 S.Ct. 2206
    , which held that the
    government must get a search warrant to obtain cell site location information
    from a cell phone company. (Id. at p. 2221.) In so holding, the court
    acknowledged that “[t]his sort of digital data—personal location information
    maintained by a third party—does not fit neatly under existing precedents.”
    (Id. at p. 2214.) Thus, in 2013, it would not have been unreasonable for the
    police to conclude that a warrant was not required to authorize the use of a
    cell site simulator.
    7
    4.
    The People argue that even assuming the warrant they obtained did
    not authorize the search, the good faith exception applies because the officers
    reasonably believed that the warrant authorized them to use a cell site
    simulator to obtain location information concerning Wilson’s cell phone.
    Wilson correctly asserts that the warrant here purported to authorize use of a
    pen register and trap-and-trace device by the telephone company to gather
    information concerning Wilson’s telephone number, without mentioning a cell
    site simulator. Although it is a close question, we agree with the People that
    the police officers’ cell site simulator search was objectively reasonable,
    particularly given the ambiguity in the case law in 2013 as to whether a
    warrant was required at all.
    The officers could have reasonably believed that the language of the
    warrant described and authorized with sufficient particularity the search to
    be undertaken. The warrant authorized the police department to use its
    “technical equipment” to obtain “geographic location estimates” of Wilson’s
    telephone. In conjunction with the warrant’s authorization of “remote
    monitoring” of Wilson’s telephone and “signals produced in . . . locations not
    open to public or visual surveillance,” we cannot say that the officers’ belief
    that the cell site simulator search was authorized by the warrant was
    objectively unreasonable. (See Ellis, supra, 270 F.Supp.3d at p. 1156
    [applying good faith exception to cell site simulator search where pen register
    warrant obtained by police made clear that purpose of the search was to
    locate defendant’s “cell phone with information about ‘cell site and/or location
    sites’ ”].) Wilson’s reliance on cases in which the language of the warrant or
    order was more limited is thus unavailing. (See, e.g., Lambis, supra, 197
    F.Supp.3d at p. 611 [“Here, the use of the cell-site simulator to obtain more
    8
    precise information about the target phone’s location was not contemplated
    by the original warrant application.”]; State v. Sylvestre (Fla.Ct.App 2018)
    
    254 So.3d 986
    , 992 [order “required the service provider to disclose
    information in its possession to the . . . Sherriff’s Office. It did not authorize
    action by the State.”]; Tracey v. State (Fla. 2014) 
    152 So.3d 504
    , 507 [the
    “application did not seek authority . . . to track the location of [the
    defendant’s] cell phone in . . . real time; and the order did not ask for access
    to real time cell site location information”].)1
    Wilson contends that the police did not act in good faith because they
    actively concealed their intent to use the cell site simulator from the judge
    who issued the warrant, apparently due to an agreement between the San
    Francisco Police Department and the federal government not to disclose
    details of the technology. We agree that a nondisclosure agreement cannot
    justify the deliberate omission of relevant information from a warrant
    application. However, here the police communicated to the judge that they
    intended to use the police department’s technical equipment to conduct
    remote monitoring and to obtain “geographic location estimates” of Wilson’s
    phone. The officer who authored the warrant request believed “the generic
    reference to geographic location would encompass [the cell site simulator]
    device without having to name all [the] different technologies [he] wanted to
    use.” Although it did not name the technology, the affidavit in support of the
    warrant explained that “[by] identifying the events when the mobile handset
    acquires the [cell phone service] network, indicating that the device is active
    and able to receive or transmit a telephone call, and on which ‘base station’,
    1State v. Andrews (Md.Ct.App. 2016) 227 Md.App.350, also cited by
    Wilson, is inapposite because unlike in the instant case, the pen register /
    trap-and-trace order obtained by the police did not require a showing of
    probable cause. (Id. at pp. 410, 412.)
    9
    or cell antennae such an event occurred, an estimation can be made as to the
    vicinity where the Subject Telephone Number is acquiring network service.
    These network access events, along with the base station configuration data,
    can be analyzed via technical equipment and software of the San Francisco
    Police Department, in order to estimate the immediate vicinity of the Subject
    Telephone Number Device.” The language of the warrant and affidavit thus
    communicated, in generic terms, what the police intended to do. Accordingly,
    this was not a situation in which the “judge in issuing a warrant was misled
    by information in an affidavit that the affiant knew was false” (Leon, supra,
    468 U.S. at p. 923), or in which the police acted in “deliberate” disregard of
    Fourth Amendment rights. (Herring, 
    supra,
     555 U.S. at p. 144.)
    Wilson also argues that the good faith exception is inapplicable unless
    the officers rely on binding appellate precedent that is subsequently
    overruled, citing Davis v. United States (2011) 
    564 U.S. 229
    , 241. However,
    while that is one situation in which the good faith exception may apply, it is
    not the only one. (See, e.g., Leon, 
    supra,
     468 U.S. at p. 926 [applying good
    faith exception where the “evidence [in the affidavit was] sufficient to create
    disagreement among . . . judges as to the existence of probable cause”]; see
    also Ellis, supra, 270 F.Supp.3d at p. 1157 [applying good faith exception to
    cell site simulator search].)
    In addition, Wilson asserts that the officers’ reliance on the warrant
    was objectively unreasonable because they should have known that a
    warrant was required to authorize a search of a private home. However, as
    discussed, the warrant allowed the police to use their technical equipment to
    conduct remote monitoring of Wilson’s cell phone, including of “signals
    produced in . . . locations not open to public or visual surveillance.”
    10
    United States v. Karo (1984) 
    468 U.S. 705
     (Karo) supports the
    conclusion that the officers’ reliance on the warrant was reasonable. Karo
    held that the monitoring of a tracking device (called a beeper) “in a private
    residence, a location not open to visual surveillance, violates the Fourth
    Amendment” absent a warrant. (Id. at pp. 714-715.) The court recognized
    that when law enforcement is using tracking technology to locate a subject, it
    may sometimes be “impossible to describe the ‘place’ to be searched, because
    the location of the place is precisely what is sought to be discovered through
    the search.” (Id. at p. 718.) Even so, the court emphasized that “it will still
    be possible to describe the object into which the beeper is to be placed, the
    circumstances that led agents to wish to install the beeper, and the length of
    time for which beeper surveillance is requested. In our view, this information
    will suffice to permit issuance of a warrant authorizing beeper installation
    and surveillance.” (Ibid.)
    Similarly, here it was reasonable for the officers to conclude that the
    language of the warrant and affidavit was sufficient in specifying Wilson and
    his phone number as the targets of the search, the circumstances that led
    police to suspect Wilson, and the applicable time frame of the search. (See
    also United States v. Tutis (D.N.J. 2016) 
    216 F.Supp.3d 467
    , 480-481
    [rejecting argument that cell site simulator warrant was not sufficiently
    particular where it did not expressly authorize a search of the defendant’s
    home, and concluding the warrant’s statement that the device would be used
    at different locations where the defendant was located was sufficient.)
    In sum, although the warrant and affidavit would not pass muster
    today, we conclude that in light of the lack of clarity in the case law in 2013,
    and the generic language in the warrant encompassing the cell site simulator
    11
    search, the police reasonably believed that their search was constitutionally
    permissible.
    B.
    Wilson asserts that the trial court erred in denying his motion for a
    mistrial based on the prosecution’s failure to timely comply with its
    obligation to disclose evidence favorable to the defense under Brady. (See
    Brady, 
    supra,
     
    373 U.S. 83
    .) After conducting an independent review (People
    v. Stewart (2020) 
    55 Cal.App.5th 755
    , 770 (Stewart)), we agree.
    1.
    Brady held that “the suppression by the prosecution of evidence
    favorable to an accused . . . violates due process where the evidence is
    material either to guilt or to punishment[.]” (Brady, 
    supra,
     373 U.S. at p. 87;
    see also Stewart, supra, 55 Cal.App.5th at p. 777 [the “ ‘touchstone of
    materiality is a “reasonable probability” of a different result,’ ” and “ ‘[t]he
    question is not whether the defendant would more likely than not have
    received a different verdict with the evidence, but whether in its absence he
    received a fair trial, understood as a trial resulting in a verdict worthy of
    confidence’ ”].) Where, as here, the issue is whether delayed disclosure
    constitutes Brady error, “ ‘ the applicable test is whether defense counsel was
    “prevented by the delay from using the disclosed material effectively in
    preparing and presenting the defendant’s case. ” ’ ” (People v. Mora & Rangel
    (2018) 
    5 Cal.5th 442
    , 467 (Mora & Rangel); see also United States v.
    Bagley (1985) 
    473 U.S. 667
    , 682-683 (Bagley) [because prosecution’s failure to
    disclose favorable evidence may cause the defense to “abandon lines of
    independent investigation, defenses, or trial strategies that it otherwise
    would have pursued,” “the reviewing court may consider directly any adverse
    effect that the prosecutor’s failure . . . might have had on the preparation or
    12
    presentation of the defendant’s case”]; In re Bacigalupo (2012) 
    55 Cal.4th 312
    , 334 (Bacigalupo) [“In deciding whether evidence not disclosed to the
    defense was material . . . , we consider how the nondisclosure affected the
    defense investigation and trial strategy.”].)
    2.
    As the People concede, until halfway through the trial, the prosecution
    failed to disclose the final eight pages of the lead investigating officer’s
    chronological report, which details the steps he took to investigate the crime.
    The prosecution did not disclose the updated report until 2019, even though
    the final entry in the file dates back to 2014, the officer provided the material
    to the prosecution in 2016, and the defense repeatedly requested an updated
    version. Before we assess its impact, we first summarize the new evidence.
    Otis’s Feud with Quinten M.
    Wilson points to entries in the chronological report indicating that
    another individual who had a motive to kill Otis had previously hired two
    men to murder Otis’s family member in San Francisco. Otis had been
    involved in a “feud” with someone named Quinten M. According to police,
    Otis and an associate shot and killed Quinten M.’s cousin about five months
    before Otis was murdered. Shortly after Quinten M.’s cousin was killed,
    Otis’s cousin was murdered in San Francisco. The chronological report listed
    the name of Otis’s murdered cousin as well as the address in San Francisco
    where the homicide occurred. A San Francisco police sergeant had reason to
    believe that Quinten M. hired two men, Stephone B. and David H., to kill
    Otis’s cousin. The police believed two other murders resulted from the same
    feud.
    According to police testimony, they ultimately ruled out Stephone B.
    and David H. as suspects because the cell phone numbers that police believed
    13
    they were using five months earlier were not identified as being in the
    vicinity at the time of the murder. However, the investigating officer testified
    that he had “no way of knowing” whether the two men had changed phones
    by the time of the murder, and “it would be impossible to determine whether
    they were standing there [at the shooting] and their cellular phone was off.”
    By the time of the trial in 2019, David H. was deceased.
    Jacque B.
    The chronological report also contained information concerning the
    police investigation of a suspect named Jacque B., who matched Demetria
    B.’s sole description of the shooter and was associated with Quinten M.
    Defense counsel was aware that police had tested the nine-millimeter pistol
    for DNA from someone by this name but did not know how he was related to
    the case. A confidential informant told police that Jacque B. was the second
    shooter with Wilson. The police also received information that Jacque B. was
    known to use a nine-millimeter pistol with an extended magazine. The
    chronological report stated: “It should be noted that Jacque B[.] fits the
    description of the 2nd shooter, which is unique as the 2nd shooter was tall,
    skinny, and a light skinned [black male]. The 2nd shooter also used a 9mm
    pistol with an extended magazine.” The lead police investigator testified that
    he ultimately ruled out Jacque B. as a potential suspect, but he did not
    explain the basis of that conclusion.
    The Leaseholder of the Montoya Street Apartment
    The chronological report also contained information concerning
    Kenneth L., one of two tenants named on the lease for the Montoya Street
    apartment. The defense had been unsuccessful in locating him. According to
    the chronological report, the police located Kenneth L. at an address in
    Richmond, and he told them that he had sublet the Montoya Street
    14
    apartment to a woman who provided access to Wilson, telling police her
    name.
    Eyewitness Description of Shooter
    The new evidence included a statement from an eyewitness who told
    police that the shooter she saw was a 5’7” male with a dark complexion, a red
    bandanna face mask, all black baggy clothing, and a hooded jacket. She told
    police that she was able to see the complexion of the shooter because she
    could see the area above the bandanna, around the shooter’s eyes. The
    defense examined her at a hearing after the delayed disclosure, but at that
    point (five years after her statement to police) she testified that she did not
    remember the shooting, and the defense did not call her as a witness at trial.
    Other Suspects
    The omitted pages of the chronological report also reported that Vernon
    C., whose DNA was found on the murder weapon, had met with several men
    at a motel two months after the shooting and that police seized guns from an
    individual named Steve H., whom they suspected of being one of the shooters
    or a lookout.
    3.
    We conclude that the evidence concerning Otis’s feud with Quinten M.,
    Jacque B., and Kenneth L. was both favorable and material.
    With respect to the feud with Quinten M., as the People acknowledge,
    evidence that another team of shooters had a motive to kill the victim could
    certainly be favorable to Wilson. The People nonetheless assert that the
    information in the chronological report was not favorable because it was
    insufficient to allow the defense to introduce the evidence at trial under a
    third-party liability theory. (See People v. Sandoval (1992) 
    4 Cal.4th 155
    , 176
    [“ ‘[E]vidence of mere motive or opportunity to commit the crime in another
    15
    person, without more, will not suffice to raise a reasonable doubt about a
    defendant’s guilt: there must be direct or circumstantial evidence linking the
    third person to the actual perpetration of the crime.’ ”].)
    However, we must assess the Brady material “with an awareness of the
    difficulty of reconstructing in a post-trial proceeding the course that the
    defense and the trial would have taken had the defense not been misled by
    the prosecutor’s incomplete response” to the defendant’s discovery request.
    (Bagley, supra, 473 U.S. at p. 683.) Here, the information in the
    chronological report was not limited to motive; it also indicated that Otis’s
    cousin was murdered by two men in San Francisco just months before he
    himself was killed by two men in San Francisco. The information would have
    allowed the defense to discover the police reports and track down witnesses.
    In addition, it would have enabled the defense to investigate whether the
    modus operandi, location, physical descriptions of the men hired by Quinten
    M. or other circumstances of the cousin’s murder provide circumstantial
    evidence that the same perpetrators were involved here. Because the defense
    could have used the information effectively to further its case, the material
    was favorable. (See In re Pratt (1999) 
    69 Cal.App.4th 1294
    , 1312 (Pratt) [“
    ‘Evidence is “favorable” [under Brady] if it either helps the defendant or
    hurts the prosecution[.] ’ ”]; see also Bagley, 
    supra,
     473 U.S. at p. 676
    [evidence is “evidence favorable to an accused, [citation], . . . [where] if
    disclosed and used effectively, it may make the difference between conviction
    and acquittal”].)
    Similarly, the disclosure that Jacque B. was a potential suspect was
    favorable to the defense. Although the informant stated that Jacque B. was
    the second shooter “with” Wilson, the identification of a potential suspect
    whose associate (Quinten M.) had a motive to kill the victim would have
    16
    undermined the prosecution’s case. Jacque B. was known to use the same
    kind of weapon as the nine-millimeter murder weapon, and given his height
    and skin color he was arguably a closer match to the lone eyewitness
    description presented at trial.
    Further, while Jacque B.’s potential involvement did not necessarily
    rule out Wilson, it made it less likely that Wilson was one of the shooters.
    Once the shooter with the nine-millimeter pistol was accounted for, there was
    little pointing to Wilson as the second shooter: there was no physical
    description of the other shooter presented at trial; the .45-caliber handgun
    was never found, and the only evidence the prosecution had that specifically
    tied Wilson to the other gun were text messages indicating he was selling a
    .45-caliber pistol the day before the shooting and the fact that RWS brand
    cartridges were found in the Montoya Street apartment. In addition, while
    Wilson has a light complexion, the newly-disclosed eyewitness reported that
    the shooter she saw was “dark complected.”
    The information concerning leaseholder Kenneth L. was likewise
    favorable to Wilson. The prosecution’s case depended heavily on convincing
    the jury that the nine-millimeter pistol, together with numerous other items
    found in the Montoya Street apartment, belonged to Wilson. The defense was
    unable to find witnesses to testify on the critical issue of access to the
    apartment, and instead relied on the names on the lease, bills, and other
    documents found at the apartment, and differing sizes of clothing found
    there, to argue that others had access. Interviewing Kenneth L. and the
    subtenant he identified may have allowed the defense to strengthen its
    theory that others had access and to present witnesses on this key issue. (Cf.
    Pratt, supra, 69 Cal.App.4th at p. 1319 [link between defendant and getaway
    17
    car was “not compelling” where there was “strong evidence” that defendant’s
    “car was frequently used by other[s]”.)
    Further, we conclude that the delayed disclosure prejudiced Wilson by
    preventing him from using the material effectively in preparing and
    presenting his case. (Mora & Rangel, supra, 5 Cal.5th at p. 467; see Wearry
    v. Cain (2016) 
    136 S.Ct. 1002
    , 1007 (per curiam) (Wearry) [explaining that
    materiality of evidence wrongfully withheld under Brady must be evaluated
    cumulatively].) At trial, Wilson presented just three defense witnesses and
    did not put forward an affirmative theory of the crime, instead focusing on
    undermining the prosecution’s circumstantial evidence. Had Wilson received
    timely disclosure of this information, the defense could have investigated the
    Quinten M. feud, as well as Jacque B.’s involvement, and may have presented
    a plausible alternative theory on the identity of the shooters, or relied on the
    information concerning these other potential suspects to attack the
    thoroughness of the investigation. (See Bies v. Sheldon (6th Cir. 2014) 
    775 F.3d 386
    , 400-401 (Bies).) Similarly, had the prosecution disclosed Kenneth
    L.’s address and statement years earlier, the defense would have interviewed
    him and his subtenant, and it could have presented witnesses to bolster its
    argument that, because several other individuals had access to the
    apartment, the prosecution failed to establish that the items found there
    belonged to Wilson. (See Bacigalupo, supra, 55 Cal.4th at p. 334 [finding
    Brady violation where timely disclosure of witness’s statement would have
    “enhanced” defendant’s theory by allowing defense to call her as a trial
    witness].)
    However, by the time the prosecution disclosed the information in 2019,
    the prosecution had already presented 16 of its 19 witnesses, and it was too
    late for the defense to track down multiple leads and multiple individuals, at
    18
    least one of whom was dead, and reconfigure the defense’s theory of the case
    midstream. When Brady material requiring further investigation is not
    disclosed until the “trial is under way, the opportunity to use it may be
    impaired” because “[t]he defense may be unable to divert resources from
    other initiatives and obligations that are or may seem more pressing.” (Leka
    v. Portuondo (2d Cir. 2001) 
    257 F.3d 89
    , 101 (Leka).) Indeed, it took the
    police three months to locate Jacque B. in 2014. It is reasonably likely that
    the defense would have had difficulty locating him or his associates mid-trial
    five years later. Moreover, it can be “difficult . . . to assimilate new
    information, however favorable, when a trial already has been prepared on
    the basis of the best opportunities and choices then available.” (Ibid.)
    The People’s reliance on People v. Jenkins (2000) 
    22 Cal.4th 900
    , 950
    (Jenkins), is misplaced. Jenkins concerned a defendant’s claim that he was
    prejudiced when the prosecution delayed its disclosure of evidence of
    inculpatory statements by the defendant until two months after the
    preliminary hearing, which was one and one-half years prior to trial.
    (Jenkins, 
    supra,
     22 Cal.4th at pp. 950-951.) In the course of rejecting the
    claim, the court explained that it is the defendant’s burden to show that a
    continuance would not have cured any harm from the prosecution’s failure to
    timely comply with the trial court’s discovery order. (Id. at p. 950.) Jenkins
    is inapposite: “[t]he delay in disclosure did not implicate defendant’s due
    process right” under Brady because the evidence in question was inculpatory.
    (Id. at p. 951.) Further, the defendant was not prejudiced because he “had
    ample time to investigate before trial.” (Ibid.) In any event, given the
    quantity and nature of material at issue here, the prosecution’s unexplained
    years-long delay in disclosure, and the clear impact on the defense’s
    19
    investigation, preparation, and strategy, a continuance was no substitute for
    timely disclosure, and Wilson acted reasonably in requesting a mistrial.
    Particularly in light of weaknesses in the prosecution’s case, we
    conclude the belated evidence undermines confidence in the outcome of the
    trial. (See United States v. Agurs (1976) 
    427 U.S. 97
    , 113 [“[I]f the verdict is
    already of questionable validity, additional evidence of relatively minor
    importance might be sufficient to create a reasonable doubt.”]; see also
    Wearry, 
    supra,
     136 S.Ct. at p. 1006.) The prosecution’s case was entirely
    circumstantial, failed to identify a second shooter, and lacked any
    explanation of Wilson’s motive. It rested primarily on imprecise cell phone
    records, the identification of a car by an unreliable eyewitness, and the
    presence of the murder weapon and other items at an apartment with indicia
    that others beside Wilson had access.
    The cell phone records were “consistent” with Wilson being at the scene
    of the crime, but they were also consistent with him being one-half to three-
    quarters of a mile away.
    Yvette M., who claimed she saw the shooters drive away in a charcoal
    gray Nissan, testified that she was drinking that day, she was an alcoholic,
    and she would not trust her memory. When she was shown photos of a
    Nissan Sentra, Altima, and Maxima, she said they all looked the same to her.
    Although she told police she thought the car was a Nissan because she “saw
    the Nissan sign in the back,” she also told the police the car was parked
    “[t]ight” in the space directly in front of her own vehicle. The defense
    presented evidence that based on how closely the car was parked to Yvette
    M.’s vehicle and the distance from her house, she would not have been able to
    see a Nissan marking on the rear of the car. In addition, surveillance video
    showed that another gray Nissan drove past the crime scene approximately
    20
    one hour before the shooting. A few dark gray Nissans and dozens of other
    dark gray cars drove by that afternoon.
    The fact that police found the nine-millimeter murder weapon at the
    Montoya Street apartment was perhaps the most damaging evidence against
    Wilson. Police also found black clothing, a black mask, a green backpack
    containing walkie talkies and binoculars, as well as cartridges of the same
    brand as the .45-caliber casings found at the scene.
    But although Wilson did not dispute that he had access to the
    apartment, it was also undisputed that his DNA was not found on the
    murder weapon. Instead, it was Vernon C.’s DNA on the nine-millimeter
    pistol, and the presence of Vernon C.’s medical bills at the apartment
    suggested he was living there. While the prosecution’s witness testified that
    he did not see RWS brand ammunition in his crime lab “very often,” he did
    see it “periodically,” and he had “no idea” how much RWS ammunition was
    sold in the United States or in San Francisco and surrounding areas. The
    clothing—a black hoodie, pants, and beanie – is ubiquitous. Similarly,
    binoculars, walkie talkies, and backpacks can be used for many purposes
    unrelated to murder, including Wilson’s drug and gun business. While the
    parties disputed whether the black mask was the same as the one seen in the
    surveillance video, the investigating officer testified he and his daughters had
    similar masks for snowboarding.
    The prosecution also relied on other equivocal evidence, including
    evidence that Wilson’s cell phone records indicated that about 11 minutes
    after the shooting, he had left the vicinity; he attempted to flee before he was
    arrested; and in calls made from jail after his arrest, Wilson asked associates,
    including Vernon C., to retrieve unknown items for him, referring to the
    items in code. However, this evidence – like much of the prosecution’s case –
    21
    was also consistent with Wilson being a dealer of guns and drugs who did not
    wish to be detained by police.
    At the end of the day, the critical questions were the identity of the
    shooters and whether the nine-millimeter murder weapon belonged to
    Wilson. The evidence withheld by the prosecution went to the heart of these
    questions. (Cf. Bies, supra, 775 F.3d at pp. 399-400 [“Given the strength of
    the exculpatory evidence that was suppressed by the State, and the relative
    weakness of the State’s case . . . , the failure to disclose the evidence
    unquestionably put the whole case in such a different light as to undermine
    confidence in the verdict.”]; Graves v. Dretke (5th Cir. 2006) 
    442 F.3d 334
    ,
    343-344 [finding Brady violation where “there [was] no direct evidence”
    against the defendant and had defense known about the other suspect, the
    defense could have “persuasively argued” that the other suspect committed
    the murder].) We hold that the defense was prejudiced by the prosecution’s
    failure to timely disclose the information. The trial court thus erred in
    denying Wilson’s motion for a new trial.
    We need not reach Wilson’s remaining claims.
    DISPOSITION
    The judgment is reversed, and the case is remanded for further
    proceedings.
