    LENK, J.    In February, 2010, a Boston police detective
    investigating an armed robbery and shooting at a convenience
    store went to the defendant's high school, after suspicion had
    focused on the defendant as one of the three perpetrators.     The
    detective spoke with a school administrator, who informed him
    that, pursuant to school policy, she was holding the defendant's
    cellular telephone.   After consultation with his supervisor, the
    detective seized the telephone to prevent the defendant from
    retrieving it and removing evidence or destroying the device.
    At that point, however, the detective had no information that
    the cellular telephone had been used to plan, commit, or cover
    up the crime, or that it contained any evidence of the crime.
    From experience, the detective was aware, however, that cellular
    telephones frequently are used when an offense involves multiple
    perpetrators.   Sixty-eight days later, having held -- but not
    searched -- the telephone throughout that period, police
    obtained a warrant to search it on the basis of information that
    had emerged after the seizure.   A forensic search yielded
    evidence relevant to the investigation, which the defendant then
    3
    moved to suppress on the ground that the seizure was not
    supported by probable cause.   A judge of the Superior Court
    allowed the defendant's motion, and the Commonwealth appealed.
    In considering the Commonwealth's appeal, we confront two
    issues under the Fourth Amendment to the United States
    Constitution and art. 14 of the Massachusetts Declaration of
    Rights.   First, we consider whether the seizure was supported by
    probable cause, and, in particular, whether the detective's
    opinion that the device was likely to contain evidence, without
    more, provided probable cause allowing him to seize it.     We then
    examine whether, under the circumstances here, it was reasonable
    for police to wait almost ten weeks after seizing the device
    before applying for a warrant to search it.
    We conclude that probable cause to search or seize a
    person's cellular telephone may not be based solely on an
    officer's opinion that the device is likely to contain evidence
    of the crime under investigation and, accordingly, that the
    seizure here was not supported by probable cause.    We separately
    conclude also that, in these circumstances, the Commonwealth has
    not, in any event, met its burden of demonstrating that the
    delay of sixty-eight days between the seizure and the
    application for a search warrant was reasonable.    We therefore
    affirm the Superior Court judge's order allowing the defendant's
    motion to suppress.

    1.   Background.   The following is drawn both from the
    motion judge's findings and from uncontested facts in the record
    implicitly credited by him, with certain details reserved for
    later discussion.   See Commonwealth v. Jones-Pannell, 
    472 Mass. 429
    , 436 (2015), citing Commonwealth v. Isaiah I., 
    448 Mass. 334
    , 337 (2007), S.C., 
    450 Mass. 818
    (2008).
    On the morning of February 21, 2010, two men entered a
    convenience store in the Roxbury section of Boston.     One
    brandished a gun and demanded money from the clerk, while the
    other, apparently without a firearm, walked to the rear of the
    store and demanded money from the victim.    As the victim tried
    to flee towards the front of the store, he was shot and later
    died.   The two men then left the store and, along with a third
    male who had been waiting outside, fled the scene.
    The next day, the defendant, then sixteen years old, told
    his mother that he had participated in a robbery, along with his
    friend "Martin," and that someone had been shot.     The defendant
    also stated that he had not believed that anyone had been
    killed, and that he had been surprised to learn of the victim's
    death from that morning's newspaper.    Later that day, the
    defendant's mother called a Boston police officer whom she knew
    and asked him to visit her at home.
    The officer came to the house the next day, February 23,
    2010, and the mother told him about her son's asserted
    5
    involvement in the robbery.    She also said that, earlier that
    day, the defendant had come to her house to wash his clothes,
    and had left them in her dryer.    Later on the same day, she gave
    consent to police detectives to search the dryer and to seize
    the clothing; one of the detectives observed that it resembled
    clothing worn by one of the perpetrators of a similar
    convenience store robbery one and one-half months earlier.     Also
    on February 23, 2010, detectives obtained consent from the
    defendant's grandmother, with whom the defendant lived, to
    search his bedroom.    There, detectives saw a jacket similar to
    one worn by one of the perpetrators of the robbery-homicide on
    February 21, 2010.    The jacket subsequently was seized pursuant
    to a search warrant.
    The following day, February 24, 2010, the defendant arrived
    late to his high school.    Pursuant to the school's usual
    practice for all arriving students,2 he was searched and his
    "pay-as-you-go"3 Samsung/Sprint cellular telephone, equipped with
    a camera, was confiscated.    That afternoon, a detective
    investigating the robbery-homicide met with one of the school's
    2
    School policy required that all arriving students be
    searched and "all electronic equipment [be] taken by school
    authorities and held for the students in individual bins or
    slots in a locked cabinet."

    6
    administrators.    The administrator told the detective that the
    defendant had become "agitated" earlier that day and had left
    the school without picking up his cellular telephone.     The
    detective notified a supervisor that the school was holding the
    defendant's telephone.     Neither the detective nor the supervisor
    had, at that point, any information that a cellular telephone
    contained evidence of the robbery and shooting, but they were
    aware, based on their experience, that such devices often
    contained useful information in cases involving multiple
    perpetrators.4    The supervisor instructed the detective to seize
    the device without a warrant apparently on the basis of his
    belief that, if the defendant retrieved the device before a
    warrant could be obtained, he would destroy the device or erase
    relevant evidence.    Thereafter, the device was transported to
    the police station, where it was logged as evidence and placed
    in a special bag designed "to prevent remote intrusion."     Police
    did not search the device.
    The defendant was arrested later the same day and charged
    with murder.     In the weeks that followed, detectives assigned to
    the case applied for and executed five search warrants,
    interviewed numerous witnesses, assisted with the grand jury

    information and logs of their communications with each other.
    7
    investigation, and also were assigned to work on two other
    homicide investigations.
    On April 21, 2010, a witness told police that the defendant
    had participated in multiple robberies similar to the one on
    February 21, 2010, and that, following one of those other
    robberies, "the defendant took a photograph of the proceeds of
    [that other] robbery with his cell phone equipped with a
    camera."   On May 3, 2010, a detective applied for a warrant to
    search the defendant's cellular telephone, which was still in
    police possession, for, among other things, photographs related
    to the robbery.5   The application was allowed, and police
    thereafter searched for and seized the aforementioned
    photograph.6
    On May 19, 2010, a Suffolk County grand jury returned an
    indictment against the defendant charging him with murder in the
    first degree.   On May 1, 2014, the defendant filed a motion to
    suppress the evidence recovered from the cellular telephone.
    5
    The warrant also sought permission to search for the
    "subscriber telephone number"; "contact list, address book,
    calendar, schedules, and date book entries"; "group" and "speed
    dial" lists; "phone configuration information settings";
    "incoming, outgoing, draft, sent and deleted text messages";
    "saved, opened, and unopened voice mail messages"; "saved,
    opened, unopened, draft, sent and deleted electronic mail
    messages"; "mobile instant message chat logs, data, and contact
    information"; "any saved and[/]or stored, downloaded, or
    uploaded photographs"; and "any message alerts or WEB history."
    6
    There is no indication whether any other evidence was
    obtained from the device.
    8
    Concluding that the seizure was not supported by probable cause,
    a Superior Court judge allowed the motion.     He also noted that
    the "delay from February 24 to May 3 [approximately ten weeks]
    in obtaining the search warrant is . . . troubling."     The
    Commonwealth filed a motion to reconsider and to reopen the
    evidence.   The judge allowed the motion, conducted an
    evidentiary hearing, and affirmed the order of suppression.      The
    Commonwealth filed an application for leave to pursue
    interlocutory review in the county court, and a single justice
    denied the motion.   The single justice then allowed the
    Commonwealth's motion to reconsider, and ordered the appeal to
    proceed in this court.
    2.   Discussion.     The Commonwealth contends that the motion
    judge erred because both the seizure of the cellular telephone
    and the subsequent search were proper under the Fourth Amendment
    and art. 14.
    a.   Standard of review.    "In reviewing a ruling on a motion
    to suppress, we accept the judge's subsidiary findings of fact
    absent clear error 'but conduct an independent review of his
    ultimate findings and conclusions of law.' . . .     We [therefore]
    'make an independent determination of the correctness of the
    judge's application of constitutional principles to the facts as
    found'" (citations omitted).    Commonwealth v. Hernandez, 
    473 Mass. 379
    , 382-383 (2015).
    9
    b.   Seizure.   The Fourth Amendment and art. 14 provide
    "that every person has the right to be secure against
    unreasonable searches and seizures" of his or her possessions.
    Commonwealth v. Porter P., 
    456 Mass. 254
    , 260 (2010).     If the
    Commonwealth conducts a search or seizure without first
    obtaining a warrant, the search or seizure is "presumptively
    unreasonable" and, therefore, presumptively unconstitutional.
    Commonwealth v. Craan, 
    469 Mass. 24
    , 28 (2014).    See
    Commonwealth v. A Juvenile (No. 2), 
    411 Mass. 157
    , 162 (1991).
    The search or seizure nonetheless may be justified where the
    Commonwealth can "show that [it] 'falls within a narrow class of
    permissible exceptions' to the warrant requirement."     
    Craan, supra
    , quoting Commonwealth v. Perkins, 
    465 Mass. 600
    , 603
    (2013).
    One such exception is where there are "'exigent
    circumstances' that make obtaining a warrant impracticable."
    Commonwealth v. Washington, 
    449 Mass. 476
    , 480 (2007).     To
    justify a search or seizure on that basis, the Commonwealth
    bears "a heavy burden" to show (1) that the search or seizure
    was supported by "probable cause," such that a warrant would
    have issued had one been sought,7 and (2) that there
    7
    Thus, if police seize property without a warrant because
    they believe it to contain evidence of a crime, they must
    already have probable cause supporting the issuance of a warrant
    to search that property. See, e.g., Illinois v. McArthur, 531
    10
    "exist[ed] . . . exigent circumstances" that made obtaining a
    warrant impracticable.     See Commonwealth v. Tyree, 
    455 Mass. 676
    , 684 (2010).     This showing must be based on
    information known to police at the time, and not on knowledge
    acquired after the fact.    See Commonwealth v. Antobenedetto, 
    366 Mass. 51
    , 66 (1974); Commonwealth v. Holloway, 
    81 Mass. App. Ct. 910
    , 911 (2012).
    Here, the Commonwealth argues that, based on information
    then known to police, the seizure of the defendant's cellular
    telephone was supported by probable cause, and obtaining a
    warrant was impracticable because of exigent circumstances.     We
    turn first to the Commonwealth's argument concerning probable
    cause.
    Before police may search or seize any item as evidence,
    they must have "a substantial basis for concluding that" the
    item searched or seized contains "evidence connected to the
    crime" under investigation (citation omitted).     Commonwealth v.
    Escalera, 
    462 Mass. 636
    , 642 (2012).     In other words, the
    government must "demonstrate[] . . . a 'nexus' between the crime
    U.S. 326, 331-333 (2001) (only if police already have probable
    cause for search may they temporarily seize dwelling for period
    required to obtain warrant); Commonwealth v. DeJesus, 
    439 Mass. 616
    , 619 & n.2 (2003) (same); 3 W.R. LaFave, Search and Seizure
    § 6.5(c), at 134 (5th ed. 2012) (officers impounding property
    without warrant must "have probable cause to search the
    impounded property at the time the impounding is imposed"
    [citation omitted]).
    11
    alleged" and the article to be searched or seized (citation
    omitted).    See Commonwealth v. Matias, 
    440 Mass. 787
    , 794
    (2004).     "The nexus 'need not be based on direct
    observation.' . . .     It may be found in the type of crime, the
    nature of the [evidence] sought, and normal inferences as to
    where such" evidence may be found.     
    Id., quoting Commonwealth
    v.
    Cinelli, 
    389 Mass. 197
    , 213, cert. denied, 
    464 U.S. 860
    (1983).
    While police "need not make a showing beyond a reasonable doubt,
    . . . '[s]trong reason to suspect is not adequate.'"
    Commonwealth v. Kaupp, 
    453 Mass. 102
    , 111 (2009), quoting
    Commonwealth v. Upton, 
    394 Mass. 363
    , 370 (1985).
    "The experience and expertise of a police officer may be
    considered as a factor in the [nexus] determination."
    Commonwealth v. West, 
    55 Mass. App. Ct. 467
    , 470 (2002).
    Nonetheless, where the location of the search or seizure is a
    computer-like device, such as a cellular telephone,8 the opinions
    8
    Based on the warrant application, the cellular telephone
    in question here appears to have had various capabilities
    associated with modern computers, including the ability to do
    the following: browse the Internet and keep a log of sites
    visited; send, receive, and store electronic mail messages;
    support instant messaging; create an address book and calendar;
    and take and store photographs. See Commonwealth v. Phifer, 
    463 Mass. 790
    , 797 (2012) ("today's cellular telephones are
    essentially computers"); United v. Flores-Lopez, 
    670 F.3d 803
    ,
    805-806 (7th Cir. 2012) ("a modern cell phone [should be treated
    as] a computer" even where "the record does not indicate the
    brand, model, or year of the defendant's cell phone, so we do
    not know how dumb or smart it is").
    12
    of the investigating officers do "not, alone, furnish the
    requisite nexus between the criminal activity and the [device]
    to be searched" or seized.     Commonwealth v. Anthony, 
    451 Mass. 59
    , 72 (2008) (computer search).    See Commonwealth v. Kenney,
    
    449 Mass. 840
    , 846 (2007) ("We do not rely on [the officer]'s
    conclusion as to what the facts in the affidavit mean to him as
    'a talismanic formula' . . . to provide probable cause [to
    search computer] where evidence to support such a finding is
    otherwise lacking" [citation omitted]).
    Rather, police first must obtain information that
    establishes the existence of some "particularized evidence"
    related to the crime.   Commonwealth v. Dorelas, 
    473 Mass. 496
    ,
    502 (2016).   Only then, if police believe, based on training or
    experience, that this "particularized evidence" is likely to be
    found on the device in question, do they have probable cause to
    seize or search the device in pursuit of that evidence.     
    Id. at 498,
    503 (police knew that defendant had been "receiving
    threatening [tele]phone calls and threatening text messages on
    his [tele]phone"; probable cause to search telephone for that
    "particularized evidence").9
    9
    See Commonwealth v. Kaupp, 
    453 Mass. 102
    , 107-114 (2009)
    (police knew that defendant possessed electronic copies of
    pirated movies, but not that he had child pornography; officer
    averred that movies and pornography often stored on personal
    computer; probable cause only for pirated movies, as police had
    prior information establishing their existence); Commonwealth v.
    13
    Here, prior to seizing the defendant's cellular telephone,
    police had received information that the robbery and homicide
    under investigation had been committed by several people, that
    the defendant likely was one of those people, and that he owned
    a cellular telephone.   They also knew from experience that
    coventurers often use cellular telephones to communicate with
    each other, and that these devices may contain evidence of such
    communications.   According to their own statements, however, the
    detectives here did not have any "information that [a] cell
    phone was used in the crime under investigation," nor did they
    claim that there existed a particular piece of evidence likely
    to be found on such a device.   In essence, then, their decision
    to seize the defendant's cellular telephone was made because
    (a) they had reason to believe that the defendant had
    participated with others in the commission of a robbery-homicide
    and (b) their training and experience in cases involving
    multiple defendants suggested that the device in question was
    likely to contain evidence relevant to those offenses.
    Anthony, 
    451 Mass. 59
    , 70-71 (2008) (police knew that defendant
    collected and transmitted illicit images; probable cause to
    search computer because detective "opined . . . that individuals
    who collect [such images] tend to keep this information in
    various media forms, including computers"); Commonwealth v.
    Kenney, 
    449 Mass. 840
    , 845-846 (2007) (same); Commonwealth v.
    McDermott, 
    448 Mass. 750
    , 764-766, cert. denied, 
    552 U.S. 910
    (2007) ("defendant had asked several coworkers to witness the
    execution of his will just days before the shootings"; probable
    cause to search computer for will).
    14
    This, without more, does not satisfy the nexus requirement.
    "Information establishing that a person [may be] guilty of a
    crime does not necessarily constitute probable cause to search"
    or seize the person's cellular telephone, even where the police
    believe, based on their training and experience in similar
    cases, that the device is likely to contain relevant evidence
    (citation omitted).   Commonwealth v. Pina, 
    453 Mass. 438
    , 441
    (2009).   Rather, even where there is probable cause to suspect
    the defendant of a crime, police may not seize or search his or
    her cellular telephone to look for evidence unless they have
    information establishing the existence of particularized
    evidence likely to be found there.10
    The Commonwealth argues, however, that the detectives
    possessed the functional equivalent of such information in the
    form of the commonsense notion that "cellular telephones
    are . . . necessary to social interactions."   See Commonwealth
    v. Augustine, 
    467 Mass. 230
    , 245-246 (2014), S.C., 
    470 Mass. 837
    (2015).   On this basis, police inferred that, if the defendant
    planned and committed multiple crimes with two coventurers, it
    was likely he did so, at least in part, using his cellular
    10
    Of course, if the device is not seized as evidence, but,
    for example, is temporarily impounded following an inventory
    search of an arrestee, this requirement has no relevance. See
    Illinois v. Lafayette, 
    462 U.S. 640
    , 643 (1983) ("justification
    for such searches [and seizures] does not rest on probable
    cause").
    15
    telephone, and that evidence of these communications would be
    found on the device.
    It may well be the case that "many of [those] . . . who own
    a cell phone [in effect] keep on their person a digital record
    of nearly every aspect of their lives," including, presumably,
    communications with their coventurers.    See Riley v. California,
    
    134 S. Ct. 2473
    , 2490 (2014).    Nonetheless, the Commonwealth's
    argument is unavailing.   While probable cause may be based in
    part on police expertise or on "the practical considerations of
    everyday life," see 
    Kaupp, 453 Mass. at 111
    , such considerations
    do "not, alone, furnish the requisite nexus between the criminal
    activity and the places to be searched" or seized.    
    Anthony, 451 Mass. at 72
    .   See 
    Pina, 453 Mass. at 441-442
    (officer's
    practical experience insufficient basis for probable cause where
    no "particularized information").
    Moreover, the argument simply "proves too much."       See
    Coolidge v. New Hampshire, 
    403 U.S. 443
    , 480 (1971) (rejecting
    Fourth Amendment argument that would sweep too broadly).      In
    essence, the Commonwealth is suggesting that there exists a
    nexus between a suspect's criminal acts and his or her cellular
    telephone whenever there is probable cause that the suspect was
    involved in an offense, accompanied by an officer's averment
    that, given the type of crime under investigation, the device
    likely would contain evidence.   If this were sufficient,
    16
    however, it would be a rare case where probable cause to charge
    someone with a crime would not open the person's cellular
    telephone to seizure and subsequent search.   See 
    Riley, 134 S. Ct. at 2492
    (only "inexperienced or unimaginative law
    enforcement officer . . . could not come up with several reasons
    to suppose evidence of just about any crime could be found on a
    cell phone").   We cannot accept such a result, which is
    inconsistent with our admonition that "individuals have
    significant privacy interests at stake in their [cellular
    telephones] and that the probable cause requirement . . . under
    both the Fourth Amendment . . . and art. 14 . . . [must] serve[]
    to protect these interests."   See 
    Dorelas, 473 Mass. at 502
    n.11.11
    11
    These interests exist even where, as here, the device
    does not appear to have all the capabilities of an upmarket
    "smart phone." See 
    Flores-Lopez, 670 F.3d at 806
    ("Even the
    dumbest of modern cell phones gives the user access to large
    stores of information"; "pay-as-you-go" cellular telephone "sold
    by Walgreens for $14.99, includes a camera, MMS [multimedia
    messaging service] picture messaging for sending and receiving
    photos, video, etc., mobile web access, text messaging,
    voicemail, call waiting, a voice recorder, and a phonebook that
    can hold 1000 entries"). Were the device to possess the
    enhanced capabilities of a "smart phone," that would merely
    implicate even greater privacy concerns. See Riley v.
    California, 
    134 S. Ct. 2473
    , 2491 (2014) ("cell phone search
    would typically expose to the government far more than the most
    exhaustive search of a house"); United States v. Wurie, 
    728 F.3d 1
    , 8 (1st Cir. 2013), aff'd sub nom. Riley v. 
    California, supra
    (cellular telephones contain "the kind of information one would
    previously have stored in one's home").
    17
    The detectives here lacked any information establishing the
    existence of evidence likely to be found on the defendant's
    cellular telephone.   We conclude, accordingly, that they lacked
    the nexus required for probable cause to seize that device.
    Lacking probable cause, the seizure was by definition improper,12
    and we need not address whether there were exigent circumstances
    justifying the decision to do so without a warrant.
    c.   Search.   Here, police eventually obtained a search
    warrant and searched the defendant's cellular telephone for
    evidence of the robbery-homicide.   Because the device initially
    was seized without a warrant, evidence recovered as a result of
    the search is not admissible unless the Commonwealth meets its
    burden of demonstrating that the search was reasonable.13   See
    
    Craan, 469 Mass. at 28
    .
    12
    The Commonwealth suggests that the seizure nonetheless
    was proper under the plain view doctrine. See Commonwealth v.
    Perkins, 
    465 Mass. 600
    , 603-604 (2013) ("Under [the plain view]
    doctrine, if police are lawfully in a position from which they
    [inadvertently encounter] an object, if its incriminating
    character is immediately apparent, and if the officers have a
    lawful right of access to the object, they may seize it without
    a warrant"). This argument fails, at a minimum, because the
    warrantless seizure of evidence found in plain view is proper
    only where "there is probable cause to associate the property
    with criminal activity." Commonwealth v. Balicki, 
    436 Mass. 1
    ,
    8 n.10 (2002), quoting Payton v. New York, 
    445 U.S. 573
    , 587
    (1980). Here, as discussed, there was no such probable cause.
    13
    The fact that, following the warrantless seizure, a
    search warrant was obtained does not shift the burden of this
    inquiry to the defendant. See State v. Johnson, 
    335 Or. 511
    ,
    521 (2003) (burden to prove reasonableness remains with State
    18
    The Commonwealth has not met this burden for two
    independent reasons.   First, the Commonwealth has not shown that
    the delay between the seizure and the filing of the application
    for a search warrant was reasonable.14   Second, the search was
    the fruit of a seizure made without probable cause.     As a
    result, any evidence obtained from the search must be
    suppressed.
    i.   Length of delay.   Police may retain an item seized
    without a warrant for "the relatively short period of time
    needed . . . to obtain a search warrant," but must release the
    item if a warrant is not obtained within that period.
    Commonwealth v. Gentile, 
    437 Mass. 569
    , 573 (2002), quoting
    Commonwealth v. Taylor, 
    426 Mass. 189
    , 195 (1997).    For this
    reason, once a warrantless seizure has been executed, the police
    "must make it a priority to secure a search warrant that
    complies with the Fourth Amendment.    This will entail diligent
    where evidence seized without warrant even though search warrant
    ultimately obtained). Cf. Commonwealth v. Midi, 46 Mass. App.
    Ct. 591, 595 (1999) (where "evidence derived from prior
    illegality," "burden [on] the government to prove that the taint
    was attenuated enough to allow admission").
    14
    The Commonwealth contends that the issue of the delay is
    not properly before us because the defendant did not raise it in
    the Superior Court. The issue of the delay was noted in the
    motion judge's first memorandum of decision, however, following
    which an evidentiary hearing was conducted at the Commonwealth's
    request. At that hearing, it was the Commonwealth's burden to
    present evidence establishing the reasonableness of the delay.
    Based on the evidence introduced, we are in a position to assess
    whether the Commonwealth met its burden.

    work to present a warrant application to the judicial officer at
    the earliest reasonable time."     See United States v. Burgard,
    
    675 F.3d 1029
    , 1035 (7th Cir.), cert. denied, 
    133 S. Ct. 183
    (2012).   If the police fail to do so, the seizure, even if
    "reasonable at its inception because based upon probable cause,"
    "may become unreasonable as a result of its duration."       Segura
    v. United States, 
    468 U.S. 796
    , 812 (1984).    See Burgard, supra
    at 1032 ("When officers fail to seek a search warrant, at some
    point the delay becomes unreasonable and is actionable under the
    Fourth Amendment").
    There is "no bright line past which a delay becomes
    unreasonable."   See Burgard, supra at 1033.   Rather, the
    reasonableness of the delay is determined by "balanc[ing] the
    nature and quality of the intrusion on the individual's Fourth
    Amendment interests against the importance of the governmental
    interests alleged to justify the intrusion."    United States v.
    Place, 
    462 U.S. 696
    , 703 (1983).    See 
    Kaupp, 453 Mass. at 106
    .
    "[C]ourts have identified several factors highly relevant to
    this inquiry," see United States v. Laist, 
    702 F.3d 608
    , 613
    (11th Cir. 2012), among them, and of particular importance here,
    whether police acted "diligen[tly] in obtaining the warrant."
    
    Id. at 614.
    The Commonwealth argues that the delay of sixty-eight days
    was justified by the complexity of the investigation.    During
    20
    the period between the seizure of the cellular telephone and the
    filing of the application for a search warrant, the detectives
    were involved in "interviews of witnesses, an ongoing grand jury
    investigation, and the application for and execution of [five]
    other search warrants."   Where an investigation is highly
    complex, "courts 'can almost always imagine some alternative
    means by which the objectives of the police might have been
    accomplished,' but that does not necessarily mean that the
    police conduct was unreasonable" (citation omitted).     See
    
    Burgard, 675 F.3d at 1034
    .     In addition, the Commonwealth notes
    that, during the period immediately following the seizure in
    question, the team of detectives assigned to this case
    apparently also was assigned to two other homicide
    investigations.   See 
    Laist, 702 F.3d at 614
    ("we consider . . .
    whether overriding circumstances arose, necessitating the
    diversion of law enforcement personnel to another case"
    [citation omitted]).   Because of the detectives'
    responsibilities in this and other cases, there existed, in the
    Commonwealth's view, an "importan[t] . . . governmental
    interest[]," see 
    Place, 462 U.S. at 703
    , in delaying the
    application for a search warrant until the police had time to
    focus properly on that task.
    Although the information to which the Commonwealth points
    might go some way in explaining the reasons for the delay, it
    21
    does not suffice to meet the Commonwealth's burden of
    demonstrating that the delay was reasonable.   We do not question
    that the detectives diligently performed their difficult jobs.
    The relevant inquiry, however, does not concern the detectives'
    general diligence in performing their duties, but, rather,
    whether they acted "diligen[tly] in obtaining the warrant."
    
    Laist, 703 F.3d at 614
    .   Once police seized the defendant's
    cellular telephone without a warrant, they were required to
    "make it a priority" to acquire one.   See 
    Burgard, 675 F.3d at 1035
    .
    Here, it does not appear that they did so, having instead
    focused on, among other things, applying for and executing five
    other search warrants related to this case.    There also is no
    evidence that the complexity of the warrant application itself
    caused the approximately ten-week delay, or that the detectives'
    responsibility for other cases prevented them from working on
    this one.   Contrast Burgard, supra at 1034-1035 (six-day delay
    reasonable where officer called away to work on another case and
    where he requested help from others, including from assistant
    United States attorney, to draft affidavit).   On this record,
    the Commonwealth has not shown that the prolonged delay
    following the warrantless seizure was reasonable.
    The Commonwealth contends, however, that, even if police
    had a relatively minimal interest in waiting to apply for a
    22
    warrant, their actions were proper because the defendant did not
    exhibit a significant "possessory interest" in his cellular
    telephone.    See 
    Laist, 702 F.3d at 613
    (courts consider
    "significance of the interference with the person's possessory
    interest").   In particular, the Commonwealth notes that the
    cellular telephone at issue was a "pay-as-you-go" device, that
    the defendant possessed another such device, and that the
    defendant did not request that the device be returned.
    This argument does not carry the day.    Possessory interest
    is only one factor to be considered in the over-all
    reasonableness calculus.15   See 
    id. at 613-614.
      Even in
    circumstances where a defendant's possessory interest is weak, a
    delay may be unreasonable if police do not act diligently in
    applying for a warrant.    This is so in part because unreasonable
    delay "affects [not] only the person's possessory interest[],"
    but also the ability of the judiciary "promptly [to] evaluat[e]
    and correct[] improper seizures."    See 
    Burgard, 675 F.3d at 1033
    , quoting 
    Segura, 468 U.S. at 806
    .
    Because the Commonwealth has not demonstrated that the
    police acted diligently in applying for a warrant, we conclude
    15
    We also do not share the view that the defendant's
    possessory interest was lessened because he owned a "pay-as-you-
    go" cellular telephone. See Pew Internet & American Life
    Project, Teens and Mobile Phones, at 20 (Apr. 20, 2010) (such
    devices common among people who cannot afford subscription
    plans).
    23
    that it has not met its burden to show that the delay of sixty-
    eight days from the time the device was seized to the date of
    the search warrant application was reasonable.
    ii.   Fruit of unreasonable seizure.   Even if the delay were
    reasonable, any evidence recovered from the telephone would
    nonetheless require suppression on the ground that it was the
    fruit of an unlawful seizure.
    "The general rule is that evidence is to be excluded if it
    is found to be the 'fruit' of a police officer's unlawful
    actions."16   Commonwealth v. Balicki, 
    436 Mass. 1
    , 15 (2002),
    citing Wong Sun v. United States, 
    371 U.S. 471
    , 484 (1963).
    Where an item is seized without probable cause, the item and its
    "fruits" may not be introduced in evidence.   See Commonwealth v.
    Keefner, 
    461 Mass. 507
    , 518 (2012), quoting Wong Sun, supra at
    488 (evidence from search without probable cause, including
    "cellular telephone" and "all text messages" on telephone, "must
    be suppressed under the 'fruit of the poisonous tree'
    doctrine"); 
    Upton, 394 Mass. at 364
    ("exclusionary rule
    requir[es] the exclusion of evidence seized without a showing of
    probable cause").   That probable cause for a seizure emerges at
    16
    Although suppression may not always be required where
    evidence was seized unlawfully, the Commonwealth has not argued
    that any recognized exception is applicable here. See, e.g.,
    
    DeJesus, 439 Mass. at 624
    (independent source doctrine);
    Commonwealth v. Sbordone, 
    424 Mass. 802
    , 810 (1997) (inevitable
    discovery doctrine).
    24
    some point after the seizure occurred does not alter this
    conclusion.   See, e.g., Upton, supra at 367-368; Commonwealth v.
    Wedderburn, 
    36 Mass. App. Ct. 558
    , 563 (1994).   Cf. United
    States v. Reed, 
    443 F.3d 600
    , 603 (7th Cir.), cert. denied, 
    549 U.S. 874
    (2006).   Here, because the cellular telephone was
    seized unlawfully, without probable cause, any evidence
    recovered from it must be suppressed.
    Order allowing motion
    to suppress affirmed.
