Before Stark, P.J., Hruz and Nashold, JJ.
¶ 1 STARK, P.J. Jeremy Deen appeals a judgment convicting him, upon his no

- contest plea, of one count of possession of child pornography. Deen argues the circuit court erred by denying his motion to suppress evidence discovered during a search of his cell phone . Althoug h the search was conductedNo. 2020AP1399

2 pursuant to a search warrant, the phone was initially seized without a warrant, and Deen contends that the warrantless seizure violated his Fourth Amendment rights. Like the circuit court, however, we conclude that the warrantle ss seizure was permissible under the exigent circumstances exception to the warrant requirement
because , under the facts known at the time, a law enforcement officer would have reasonably believe d that the delay required to procure a search warrant would r isk
the destruction of evidence. We therefore affirm.

BACKGROUND
¶ 2 Deen was charged with four counts of possession of child pornography, based on four images that were found during a law enforcement
search of his cell phone

. As noted above, Deen moved to suppress the images, arguing, among other things, that the police had seized his phone without a

warrant in violation of the Fourth Amendment.
¶ 3 The following facts were adduced at the hearing on Deen’s
suppr ession motion. On November 20, 2017, the National Center for Missing and Exploited Children (NCMEC) received a tip indicating that an image of child pornography had been uploaded on that date from a particular IP address. 1 The tip reported that the image was uploaded through an inte rnet site called C hatstep, in a chatroom called “L ilslutz,” under the username “Josh.” An administrative subpoena was then used to determine that the IP address from which the image
had been uploaded was associated with a specific street address on Sara Street in the city of Eau Claire. The Eau Claire County Sheriff’s Office received

1 An IP address is a unique address that identifies a device on the internet. State v. Baric , 2018 WI App 63, ¶4, 384 Wis. 2d 359, 919 N.W.2d 221.No. 2020AP1399

- CR

3 NCMEC ’s tip on January 16, 2018, and shared it with the Eau Claire Police Department

. ¶ 4 Eau Claire police detective Ryan Pr ock and another officer went to the Sara Street address on January 17, 2018, and made contact with Deen outside
the home

. The officers ask ed to speak to Deen inside, and he gave them permission to enter the residence. The officers informed Deen that they had received a tip about child pornography that had come from his IP address

. In response to the officers’ questions, Deen stated that he used his cell phone to
access the internet, and that he looked at pornography on the interne t , but he did not think he had looked at any child pornography. H e stated, however, that when using internet chat rooms, “ sometimes files get dow nloaded on his phone and he has clicked on them, but he doesn’ t remember if he did or not .” Deen told the
off icers that he had heard of the Chatstep site but had never used it. The officers ascertained that Deen’s middle name is Joshua, which Prock believed connected Deen to the username “Josh” that was referenced in the NCMEC tip

. ¶ 5 At some po int during their conversation with Deen, the officers noticed that Deen had a knife on his person

. They therefore conducted a

“ pat

- frisk ” of Deen, during which they located his cell phone in one of his pockets

. The cell phone was placed on a table, and t he officers subsequently asked Deen
for consent to look at the phone. Deen responded that he needed the phone for work, and “if [the officers] could come back at a later time to get it, that would be
fine then

. ”
¶ 6 The officers then seize d Deen’s cell phone, even though they did not
have a warrant to do so

. Prock testified that the officers beli eved the phone contained evidence of possession of child pornography, and if they left the phoneNo. 2020AP1399

- CR

4 with Deen , he would have “ample opportunity to destroy the phone, to erase everything off the phone or just get rid of the phone .” Prock further testified that the police did not search the phone until they received a warrant to do so.
¶ 7 The circuit court denied Deen’ s suppression mo tion, concluding that even though the officers seized Deen’s cell phone without either a warrant or Deen’s consent, the seizure was permissible under the exigent circumstances exception to the warrant requirement “to preserve evidence, and to prevent the
d estruction thereof .” Dee n subsequently pled no contest to a single count of possession of child pornography, and the remaining counts were dismissed and
read in. Dee n now appeals, arguing that the court erred by denying his suppression motion because the warrantless seizure of his cell phone was not justified by exigent circumstances

DISCUSSION
¶ 8 Our review of a circuit court’s decision granting or denying a motion to suppress evidence presents a question of constitu tional fact, to which we apply a

two

- step standard of review

. State v. Tullberg , 2014 WI 134, ¶27, 359 Wis. 2d 421, 857 N.W.2d 120. Firs t, we uphold the circuit court’s findings of historical fact unless they are clearly erroneous

. Id. Second, we indep endently apply the
relevant constitutional principles to those facts. Id.
¶ 9 Both t he Fourth Amendment to the United States Constitution and

a rticle I, s ection 11 of the Wisconsin Constitution protect against unreasonable

5 searches and seizures. Tullberg , 359 Wis. 2d 421, ¶29. “A seizure conducted
without a valid warrant is presumptively unreasonable .” State v. Brereton , 2013 WI 17, ¶24, 345 Wis. 2d 563, 826 N.W.2d 369. N evertheless, the warrant requirement is subject to certain limi ted exceptions

. Id. One of those exceptions exists where the State can show “both probable cause and exigent circumstanc es that overcome the individual’ s right to be free from government interference .” State v. Hughes , 2000 WI 24, ¶17, 233 Wis. 2d 280, 607 N.W.2d 621. Here, Deen does not dispute that law enforcement had probable cause to believe that his cell phone contained evidence of a crime. The only issue on appeal is whether exigent circumstances were present. 3

¶ 10 Courts have rec ognized that exigent circumstances exist where there
is a risk that evidence will be destroyed if officers delay performing a search or
seizure in order to obtain a warrant. See i d. , ¶ 25. The test to determine whether exigent circumstances justify a warrantless search or seizure to prevent the destruction of evidence is objective , and asks “ whether a police officer, under the facts as they were known at the time, would reasonably believe that delay in

3 The State observes that, based on the United States Supreme Court’s decision in Illinois v. McArthur , 531 U.S. 326 (2001), “some federal courts have imposed additional requirements beyond the required probable cause and exigency showing to jus tify an exigent seizure of evidence .” Specifically, the State notes that some federal courts have interpreted McArthur to require a showing that the warrantless seizure lasted “ no longer than reasonably necessary for the police, acting with diligence, to o btain the warrant,” and a showing that the police “ made reasonable efforts to reconcile their law enforcement needs with the demands of personal privacy .” See , e.g. , United States v. Burton , 756 F. App’x 295, 299 (4th Cir. 2018) (quoting McArthur , 531 U. S. at 332

- 33 )

. The State asserts that both of these additional requirements were satisfied in the instant case. Deen does not address these additional requirements in his appellate briefs, much less develop any argument that they were not satisfied. Dee n has therefore conceded the issue. See Charolais Breeding Ranches, Ltd. v. FPC Sec. Corp. , 90 Wis. 2d 97, 109, 279 N.W.2d 493 (Ct. App. 1979). In any event, given Deen’s failure to address these additional requirements, we take no position regarding their applicability in this
case.No. 2020AP1399

6 procuring a search warrant would

... risk destruction of evidence .” Id. , ¶24. The State bears the burden of proving that exigent circumstances exist in a given case. State v. Richter , 2000 WI 58, ¶29, 235 Wis. 2d 524, 612 N.W.2d 29.
¶ 11 Like the circuit court, we conclude the State met its burden in this

case to demonstrate the existence of exigent circumstances justifying the warrantless seizure of Deen’s cell phone to prevent the destruction of evidence. As noted above, it is un disputed that the officers had probable cause to believe that Deen’s phone contained evidence of a crime

— i.e., possession of child pornography. During the officers’ questioning of Deen, he became aware that they were investigating a tip that child pornograp hy had been uploaded from an
IP address associate d with his residence, and the officers questioned him about his internet use and his p ornography viewing habits

. In response to the officers’ questioning, Deen specifically told them that he used h is cell phone to access the
internet and view pornography

. Deen also became aware during the interview that
the officers wanted to search his cell phone , as they asked for his consent to do so

. Under these circumstances, the officers could reasonably con clude

— as Prock
testified at the suppression hearing

— that if they allowed Deen to retain the phone while they left to obtain a search warrant, he would destroy the phone, get rid of it,

or erase evidence from it.
¶ 12 The United States Suprem e Court has recognized that it is objectively reasonable for the police to conclude that the warrantless seizure of property is necessary to prevent the destruction of evidence where a suspect is aware of law enforcement’s desire to search the property as part of an investigation

. See Illinois v. M cArthur , 531 U.S. 326, 332 (2001). In M cArthur , the defe ndant’s wife asked the police to accompany her to the trailer where she
lived with the defendant in order to “keep the peace” while she removed herNo. 2020AP1399

- CR

7 belongings. Id. at 328

. When she exited the trailer after collecting her things , she
told an officer that the defendant had “dope” in the trailer, which he had slid under
the couch. Id. at 329. The officer then knocked on the trailer door and asked the defendant for permission to search the trailer, which the defendant denied

. Id.
The officer subsequently told the defendant, who was by that time on the porch,
that he could not re

- enter the tr ailer unless accompanied by a police officer. Id.
After obtaining a warrant, the police searched the trailer and found marijuana and drug paraphernalia inside

. Id.
¶ 13 The Supreme Court determined that the officers’ warrantless seizure
of the defendant was justified under the exigent circumstances exception to the warrant requirement

. Id. at 331

- 32. The Court stated that the police had “good reason to fear that, unless restrained , [the defendant] would destroy the drugs before they cou ld return with a warrant.” Id. at 332. In support of that conclusion , the Court explained that the officers “reasonably might have thought” that the
defendant : realized his wife knew about his marijuana stash; observed that his wife was angry or frighte ned enough to ask the police to accompany her to the trailer; saw that his wife had spoken to the police after leaving the trailer; and
noticed that she had walked off with one of the officers , while another officer
remained outside to observe the trailer. Id. Based on tho se facts, the Court stated the officers “reasonably could have concluded that [the defendant], consequently suspecting an imminent search, would, if given the chance, get rid of the drugs
fast .” Id.
¶ 14 Relying o n McArthur , other courts have upheld warrantless seizures
of electronic devices based on the risk that a suspect would destroy those devices , or the evidence they contained , after learning of law enforcement’s investigation. For instance, in United States v. Burton , 756 F. App’x 295 , 297 (4th Cir. 2018),No. 2020AP1399

- CR

8 an officer questioned the defendant at the police station about an allegation that
the defendant had used his cell phone to take an up

- skirt photograph of a woman. During the interview, the officer made it clear that he disbelieved the defendant’s explanation for his conduct. Id. At the end of the interview, the officer seized two cell phone s that the defendant had brought to the station, and two days later the pol ice obtained a warrant to search the phones. Id.
¶ 15 The Fourth Circuit concluded the officer’s warrantless seizure of the
cell phones was justified under the exigent circumstances exception, given the defendant’s knowledge that he was the subject of an investigation into his use of cell phone s to take up

- skirt photos, and the defendant’s awareness that the officer was skeptical of his version of events

. Id. at 29 8

- 9 9. The court reasoned: “Given
the ease with wh ich [the defendant] could have deleted, transferred, or otherwise removed the digital photos from the phones, [the officer] reasonably assumed [the defendant] might destroy any evidence contained on the phones, or the devices
themselves .” Id

. at 299. Sta ted differently, the officer had “good reason to fear”No. 2020AP1399

- CR

9 that the defendant “ would destroy digital evidence if allowed to depart the police station with the phones .” 4 Id. (quoting McArthur , 531 U.S. at 332).
¶ 16 Similarly, in this case, the officers had good reason to fear that Deen would destroy digital evidence on his cell phone

— or the phone itself

— if they allowed him to keep the phone while they left to obtain a search warrant. Deen was aware of the officers’ investigation and knew th at they were specifically interested in searching his cell phone for evidence of child pornography. Deen could have easily destroyed the phone or deleted evidence from it during the time
it took the officers to obtain a search warrant. On these facts, th e officers could reasonably believe that the delay needed to obtain a warrant would risk the
destruction of evidence

. See Hughes , 233 Wis. 2d 280, ¶24.
¶ 17 Deen nevertheless asserts, for four reasons, that it was not
reasonable for the off

icers to conclude that the warrantless seizure of his cell phone was necessary to prevent the destruction of evidence. First, Deen notes that

4 Other federal and state courts have reached the same conclusion in cases presenting similar facts

. See, e.g. , United States v. Pérez

- Diaz , 848 F.3d 33, 36

- 37, 40

- 41 (1st Cir. 2017) (concluding that officers reasonably seized the defendant’s residence to prevent him from destroying evidence contained on computers located inside while the officers obtained a search warrant, in circumstances where the defendant was aware that the officers were looking for evidence of child pornography and the officers had specifically asked the defendant to turn on his laptop, which he refused to do ); United States v. Bradley , 488 F. App’x 99, 100

- 01, 103 (6th Cir. 2012) ( holding that exigent circumstances justified the warrantless seizure of the defendant’s laptop where the defendant was aware that law enforcement was investigating an upload of child pornography and knew that his lap top contained an identifying marker associated with that upload, as “[c]ourts have doubted the wisdom of leaving the owner of easily

- des t ructible contraband in possession of that contraband once the owner is aware that law

- enforcement agents are seeking a search warrant ”); State v. Deem , 849 S.E.2d 918, 921

- 22, 926

- 27 (W. Va. 2020) (upholding the warrantless seizure of a suspect’s cell phone where the police believed the suspect had used the phone in the commission of a crime , the suspect was aware of the i nvestigation and knew the police believed that his phone contained pertinent evidence , and a reasonable officer would have recognized that the potential evidence on the phone “ could have been quickly damaged or destroyed ”).No. 2020AP1399

- CR

10 the NCMEC tip was generated on November 20, 2017, approximately two months
before the date when the police questioned him and seized his phone

. Deen

asserts the police had no information t o suggest that , during that two

- month period, he had attempted to get rid of any electronic devices that he used to access the internet or had attempted to delete data from h is phone. Deen asserts it was unreasonable for the officers “to determine that destructio n of evidence was
imminent when

... Deen had not done anything in the prior months to indicate he might destroy evidence .” Deen also suggests that it was unreasonable for the officers to conclude there was a risk that he would destroy his phone, given that he
had expressly told them he needed to keep the phone so that he could use it for
work.
¶ 18 Deen is correct that, before the officers questioned him at his residence, there was nothing to suggest that he would destroy either his cell phone or any evidence it contained. As the State correctly notes, however, the situation changed when the officers spoke to Deen about their investigation. Again , during that conversation, Deen became aware that the officers were investigating an upload of child pornography from an IP address associated with his residence, and that they wanted to search his cell phone in connec tion with their investigation.
As we have already explained , under these circumstances, it was reasonable for the officers to conclude that the delay required to obtain a search warrant would
risk the destruction of evidence.
¶ 19 Furthermore, while it is true Deen told the officers that he needed his phone for work, Deen cites no legal authority in support of the proposition that the officers were required to accept his assertion in that regard. Given the surrounding circumstances, the officers could have instead reasonably concluded that Deen lied about needing his phone for work to provide an excuse for refusing to let themNo. 2020AP1399

- CR

11 take the phone. The officers could have also reasonably concluded that, even if Deen needed his phone for work, he would have been willing to destroy the phone to prevent them from discovering incriminating evidence that it contained. In the alternative, the officers could have reasonably concluded that while Deen’s need to use his phone for work may have prevented him from destroying the phone
itself , it would not have prevented him from deletin g incriminating evidence

. Under any of these scenarios, the officers could have reasonably concluded that there was a risk Deen would destroy either the phone or the evidence it contained if they allowed him to keep the phone while they left to obtain a search warrant.
¶ 20 Second, citing State v. Kiekhefer , 212 Wis. 2d 460, 569 N.W.2d 316 (Ct. App. 1997), Deen argues the dispositive inquiry is whether the officers had
sufficient information at the moment they entered Deen’s hom e to support a reasonable belief t hat evidence might be destroyed

. Deen notes that in Kiekhefer , we concluded exigent circumstances did not justify law enforcement’s warrantless entry into the de fendant’s bedroom because: (1) although the officers believed the defendant was in possession of a large amount of marijuana, “the presence of contraband without more does not give rise to exigent circumstances”; (2) a large quantity of marijuana “could not be easily or quickly de stroyed in [the defendant’s] bedroom” ; and (3) the officers “were not confronted with the sounds of destruction emanating from within [the defendant’s] room .” Id. at 478

- 7 9. Deen contends that this case is similar to Kiekhefer because at the moment the officers entered Deen’s home, they merely believed that contraband (i.e., evidence of child pornography) might be present, but that contraband could not have been easily or quickly destroyed, and the officers did not hear any sou nds that indicated Deen was about to destroy it

.No. 2020AP1399

- CR

12 ¶ 21 Deen’s reliance on Kiekhefer is misplaced. He is correct that the Kiekhefer court framed the relevant inquiry as “ whether the facts, as they appeared at the moment of entry, would lead a reasonable, experienced agent to believe that evidence might be destroyed before a warrant could be secured.” Id. at 478 (quoting United States v. Rivera , 825 F.2d 152, 156 (7th Cir. 1987)). Kiekhefer referred to the moment of entry, however, because the issue in that case
was whether the police had violated the Fourth Amendment by entering the defendant’s bedroom without a warrant. See id. at 466, 474

- 76. Similarly , Rivera , which the Kiekhefer court relied upon, addressed whether officers violated the Fourth Amendment by entering a hotel room without a warrant. See Rivera , 852 F.2d at 156

- 57.
¶ 22 Thus, in both Kiekhefer and Rivera , the alleged Fourth Amendment
violation occurred at the moment law enforcement entered into a legally protected
space. As such, in those cases, the relevant question was whether law enforcement had enough information to support a reasonable belie f at the moment of entry that evidence might be destroyed be fore a warrant could be secured. Here, in contrast, the alleged Fourth Amendment violation did not occur at the moment the officers entered Deen’s home. Prock testified during the suppression hearing that Deen gave the officers permission to enter the ho me , and Deen does not argue otherwise on appeal. Instead, Deen contends the officers violated the Fourth Amendment when they subsequently seized his cell phone

. On these facts, the relevant inquiry
is whether a n officer would have reasonably believed at the moment the phone was seized that evidence on the phone might be destroyed be fore a warrant couldNo. 2020AP1399

- CR

13 be secured. As e xplained above, a n officer would have reasonabl y drawn that
conclusion under the circumstances of this case

. 5

¶ 23 Third, citing the criminal complaint, Deen notes that when the officers questioned him about his internet usage, he told them that he used both his cell phone and a laptop computer to access the internet. Deen then argues that “[t]he inconsistency i n seizing the phone but not the laptop demonstrates that the seizure was based on speculation rather than a reasonable belief that evidence would be destroyed before a warrant could be secured .”
¶ 24 No testimony or other evidence was introduced at the s uppression hearing, however, to support the assertion that Deen told the officers he used both
his cell phone and a laptop to access the internet. The suppression hearing

5 We acknowledge that the prese nce of contraband, without more, does not give rise to exigent circumstances

. See State v. Kiekhefer , 212 Wis. 2d 460, 478, 569 N.W.2d 316 (Ct. App. 1997). In this case, however, additional factors were present supporting a reasonable belief that if the officers allowed Deen to keep his cell phone while they obtained a warrant, there was a risk that he would destroy evidence. Again, Deen was aware that law enforcement was investigating an upload of child pornography from his home’s IP address, and he knew that the officers wanted to search his phone in connection with their investigation. Contrary to Deen’s assertion, under these circumstances it is not dispositive that the officers did not hear any sounds indicating that Deen was actively destroying evidence before they seized his p hone

. We also reject Deen’s argument that, like the large quantity of marijuana in Kiekhefer , the evidence at issue in this case could not have been quickly or easily destroyed. Deen cites State v. Gralinski , 2007 WI App 233, ¶31, 306 Wis. 2d 101, 743 N.W .2d 448 , where we stated that “ possess ion of child pornography on one’ s computer differs from possession of other contraband in the sense that the images remain even after they have been deleted .” Be that as it may, rather than deleting any images of chil d pornography on his phone, Deen could have destroyed the evidence by destroying the phone itself, or by transferring it to another person or location to prevent the police from finding it. Although Deen suggests that the officers could have accessed imag es on his phone in other ways even without possession of the phone

— for instance, via “the cloud”

— his argument in that regard is purely speculative. There is nothing in the record to suggest that the officers knew at the time they seized Deen’s phone

— or th at a reasonable officer in their position would have known

— that any incriminating images on the phone were backed up to “the cloud” or would have been otherwise accessible even if Deen destroyed the phone itself.No. 2020AP1399

- CR

14 transcript does not contain any reference to a laptop or a computer of any kind,
and no exhibits were introduced into evidence during the hearing. We have previously stated that when reviewing a suppression order, an appellate court “ is not limited to examination of the suppression hearing record ” but may also consider “the trial evidenc e ,” “the evidence at the preliminary hearing,” and “the record supporting issuance of a warrant .” State v. Gaines , 197 Wis. 2d 102, 106
n.1 , 539 N.W.2d 723 (Ct. App. 1995). Deen cites no authority for the proposition that we may also consider the criminal complaint when review ing a circuit court’s decision on a motion to suppress.
¶ 25 Moreover, even if we considered the criminal complaint, it provides

a reas onable explanation for the officer s ’ decision to seize the cell phone, but not
the laptop. Specifically, the complaint states that Deen told the officers “he just bought the laptop computer [,] and before the computer he would only use his cell phone for i nternet .” Because the tip from NCMEC was approximately two months old at the time the officers interviewed Deen, they could reasonably assume that any evidence related to that tip would be found on Deen’s cell phone, rather than his recently acquired lapt op. We agree with the State that under these circumstances, instead of demonstrating a lack of exigent circumstances, the officers’ decision to seize only Deen’s cell phone shows that they “reasonablyNo. 2020AP1399

- CR

15 limited their seizure to the electronic device most li kely to contain evidence of the crime they were investigating .” 6

¶ 26 Fourth and finally , Deen asserts that the exigent circumstances exception does not apply here because any exigency related to the risk of destruction of evidence was caused by the officers’ own unreasonable conduct. It is well established that police officers “ may not benefi t from exigent
circumstances that th ey themselves create.” State v. Robinson , 2010 WI 80, ¶32, 327 Wis. 2d 302, 786 N.W.2d 463. However, in Kentucky v. King , 563 U.S. 452 , 462 (2011), the Supreme Court clarified that the exigent circumstances exception

a pplies “when the conduct of the police preceding the exigency is reasonable” within the meaning of the Fourth Amendment. As such, where the police “ did not create the exigency by engaging or threatening to engage in conduct that violates
the Fourth Amendm ent, warrantless entry to prevent the destruction of evidence is
reasonable and thus allowed .” Id.

6 Deen argues we cannot consider the state ment from the criminal complaint that he had just purchased his laptop and had previously used only use his cell phone to access the internet because there was no testimony regarding that statement du ring the suppression hearing. As noted above, however, there was no testimony about the laptop whatsoever during the suppression hearing, and Deen himself relies on the criminal complaint to support his argument that the officers’ failure to seize the laptop demonstrates a l ack of exigent circumstances. Deen cannot rely on the criminal complaint to support his argument that exigent circumstances were not present, and then fault the State for relying on that same document to refute his argument. In any event, even absent Deen’s statement that he had just purcha sed his laptop and had previously used only his cell phone to access the internet, we would conclude that the officers’ seizure of only the phone, and not the laptop, does not show a lack of exigent circumstances. The officers could have reasonably conclu ded that it is easier to destroy, hide, or lose a cell phone than a laptop, which is larger in size. On that basis, the officers could have reasonably concluded that any possible evidence on Deen’s cell phone was at a greater risk for destruction than evi dence on his laptop.No. 2020AP1399

- CR

16 ¶ 27 Here, the officers did not create the exigency that necessitated the seizure of Deen’s cell phone by engaging or threat ening to engage in conduct that
violated the Fourth Amendment. The officers made contact with Deen outside of
his residence

. They entered the residence only after receivin g Deen’s permission
to do so. They located Dee n’s cell p hone during a pat

- frisk, w hich one of the officers initiated after observing that Deen had a knife. Deen does not argue that either the officers’ entry into his home or the pat

- frisk violated the Fourth
Amendment.
¶ 28 Nor does Deen develop any argument that the off icers violated the Fourth Amendment merely by approaching him to ask him questions related to their investigation. In any event , an argument in that regard would appear to be contrary to King , where the Court held that officers do not violate or threaten to
violate the Fourth Amendment merely by knock ing on a n individual’s door
without a warrant because , by doing so, “ they do no more than any private citizen might do .” See i

d. at 469

- 70. Similarly, in this case, the officers did no mo re than any private citizen might do by approaching Deen outside his home and asking to speak to him. We therefore reject Deen’s argument that the exigent circumstances exception is inapplicable here because the officers created the exigency.
¶ 29 For all of the foregoing reasons, we conclude that at the moment Deen’s cell phone was seized , a n officer would have reasonably believed that the delay necessary to obtain a search warrant would risk the destruction of evidence

. Consequently, l ike the circuit court, we conclude that the exigent circumstances exception to the warrant requirement applies . A s a result, the warrantless seizure of Deen’s cell phone did not violate the Fourth Amendment, and the court properly denied Deen’s suppression m otion
