No. 14CA2479, People v. Campbell — Constitutional Law —
Fourth Amendment — Reasonable Expectation of Privacy

     A division of the court of appeals considers whether a

defendant has a reasonable expectation of privacy under the United

States and Colorado Constitutions in global positioning system

(GPS) data acquired from a defendant’s ankle monitor. The division

concludes that the defendant did not have a reasonable expectation

of privacy when the GPS data was voluntarily given to law

enforcement officials by the company that owned the ankle monitor.

The division further concludes that the trial court did not err in

admitting the GPS evidence without first conducting a hearing to

assess its reliability pursuant to People v. Shreck, 22 P.3d 68 (Colo.

2001).
     The division also rejects the defendant’s contentions that he

was seized and searched in violation of the Fourth Amendment and

that the victim’s in-court identification should have been

suppressed due to an unconstitutionally suggestive out-of-court

identification procedure.

     Accordingly, the division affirms the judgment of conviction.

Cynthia H. Coffman, Attorney General, Elizabeth Rohrbough, Senior Assistant
Attorney General, Denver, Colorado, for Plaintiff-Appellee

Suzan Trinh Almony, Alternate Defense Counsel, Broomfield, Colorado, for
Defendant-Appellant
¶1    Defendant, Brandon Deshawn Campbell, appeals his

 judgment of conviction entered on jury verdicts finding him guilty of

 two counts of second degree burglary, one count of attempted

 second degree burglary, and three counts of criminal mischief. He

 contends that the trial court erred in denying his motion to

 suppress global positioning system (GPS) location data obtained via

 an ankle monitor he wore at the time of his arrest. As a matter of

 first impression, we conclude that Campbell did not have a

 reasonable expectation of privacy in the GPS data under the United

 States or Colorado Constitutions. Because we also perceive no

 grounds for reversal with regard to Campbell’s remaining

 contentions, we affirm.

                            I. Background

¶2    In late April 2012, the victim, J.P., called 911 to report an

 intruder in his home. He provided the 911 dispatcher with a

 description of the intruder and stated that he believed the suspect

 had driven away in a white Ford Explorer.

¶3    Officers stopped a white Ford Explorer about ten minutes later

 approximately three miles from the victim’s home. Campbell was

 the driver and only occupant of the vehicle. Officers searched


                                   1
 Campbell and found he was wearing an ankle monitor. A detective

 later requested and received the GPS data from the company

 owning the ankle monitor. The GPS data revealed that, within the

 month before J.P.’s home was broken into, Campbell had been at

 the location of two other homes when they were burglarized. The

 GPS data also placed Campbell at J.P.’s house at the time of the

 break-in. Campbell was convicted of two counts of second degree

 burglary, one count of attempted second degree burglary, and three

 counts of criminal mischief.

¶4    On appeal, Campbell asserts that the trial court erred by

 denying his motions (1) to suppress evidence obtained as a result of

 a seizure and subsequent search of his person; (2) to suppress the

 GPS data obtained from the ankle monitor; (3) for a hearing to

 assess the admissibility of the GPS data; and (4) to suppress J.P.’s

 show-up identification. We disagree with all these contentions.

         II. Motion to Suppress Fruit of Seizure and Search

¶5    Campbell contends that the trial court erred in denying his

 motion to suppress evidence obtained as a result of an illegal

 seizure and search of his person. He argues that the officers’ use of

 handcuffs and firearms transformed his seizure into an arrest


                                   2
 unsupported by probable cause. In the alternative, Campbell

 asserts that, even if the officers’ use of force did not constitute an

 arrest, the officers nonetheless lacked reasonable suspicion to

 conduct an investigative detention. We conclude that the stop and

 subsequent search were lawful.

                           A. Additional Facts

¶6    Officer Dave Smidt responded to J.P.’s 911 call. He was given

 the location of the alleged break-in and told that the suspect was a

 black male driving “an older model SUV, possibly a white Ford

 Explorer.” Less than ten minutes after the victim called 911, Officer

 Smidt saw a white Ford Explorer driven by a black man in the area

 of the victim’s home. He pursued the vehicle. Officer Smidt

 testified that he saw the vehicle turn rapidly without signaling

 before it eventually pulled over. He recounted that “it appeared the

 car was trying to get away from [him].”

¶7    After the vehicle stopped, Officer Smidt and another officer

 who had arrived in a separate car conducted a “felony traffic stop” ―

 they drew their weapons and ordered Campbell to exit the car, put

 his hands up, walk backwards toward them, and kneel so that he

 could be placed in handcuffs. After conducting a pat-down of


                                    3
 Campbell, the officers discovered he had an outstanding arrest

 warrant. He was then placed in the back of one of the police

 vehicles. He later made incriminating statements that he sought to

 suppress. Additionally, Campbell sought to suppress evidence of

 the officers’ discovery of the ankle monitor during the pat-down

 search.

¶8    In a bench ruling on the motion to suppress, the trial court

 stated in its findings of fact that Officer Smidt had followed

 Campbell for “a number of blocks” during which time “it looked like

 the driver was trying to get away from him.” The officer also

 observed Campbell commit traffic violations, specifically “failure to

 signal a turn” and potentially speeding by going “faster than [was]

 prudent in a residential neighborhood.” The trial court concluded

 that the officers had reasonable suspicion sufficient to stop

 Campbell, and that reasonable suspicion ripened into probable

 cause to arrest after J.P. identified Campbell as the intruder in a

 one-on-one showup conducted shortly after he was first stopped.

 As a result, the trial court denied Campbell’s motion to suppress.

                         B. Standajrd of Review

¶9     In reviewing a ruling on a motion to suppress, we defer to a

  trial court’s findings of fact if they are supported by competent

  evidence in the record. People v. King, 16 P.3d 807, 812 (Colo.

  2001). We review conclusions of law de novo. Id.

                            C. Applicable Law

¶ 10   The United States and Colorado Constitutions protect against

  unreasonable searches and seizures. U.S. Const. amends. IV, XIV;

  Colo. Const. art. II, § 7. A warrantless arrest is reasonable when an

  officer has probable cause to believe that a crime has been or is

  being committed. Devenpeck v. Alford, 543 U.S. 146, 153 (2004).

  Because probable cause is an objective inquiry, an officer’s

  subjective intent is irrelevant. See People v. Cherry, 119 P.3d 1081,

  1083 (Colo. 2005). Thus, it is irrelevant if the offense that

  established probable cause is unrelated to the offense actually

  charged by the arresting officer. Id.

¶ 11   “If an officer has probable cause to believe that an individual

  has committed even a very minor criminal offense in his presence,

  he may, without violating the Fourth Amendment, arrest the

  offender.” Atwater v. City of Lago Vista, 532 U.S. 318, 354 (2001)


                                     5
  (holding that officer had probable cause to make custodial arrest

  when he observed woman driving without wearing a seatbelt, a

  criminal violation under state traffic code); see People v. Triantos, 55

  P.3d 131, 134 (Colo. 2002); see also § 16-3-102(1)(b), C.R.S. 2017

  (authorizing a peace officer to make an arrest when “[a]ny crime has

  been or is being committed by [a] person in his presence”).

¶ 12   In the context of vehicle stops, “the decision to stop an

  automobile is reasonable where the police have probable cause to

  believe that a traffic violation has occurred.” Whren v. United

  States, 517 U.S. 806, 810 (1996); see also Cherry, 119 P.3d at

  1083. Although minor traffic infractions are classified as “civil

  matter[s]” under Colorado statute, § 42-4-1701(1), C.R.S. 2017, an

  officer may constitutionally stop a driver based on observation of

  even a minor traffic infraction. See Cherry, 119 P.3d at 1084

  (concluding that officer’s observation of defendant committing two

  class B traffic infractions justified stop); see also People v. Chavez-

  Barragan, 2016 CO 16, ¶ 10, 365 P.3d 981, 983 (“Suspicion of even

  a minor traffic offense can provide the basis for a stop.”); People v.

  Altman, 938 P.2d 142, 145 (Colo. 1997) (concluding that “troopers




                                     6
  had a reasonable suspicion that criminal activity had occurred or

  was occurring” when they observed minor traffic infractions).

                               D. Analysis

¶ 13   We conclude that the officers constitutionally stopped

  Campbell on the basis of traffic violations witnessed by Officer

  Smidt. Further, the officers had probable cause to believe Campbell

  was committing the felony of vehicular eluding, and therefore

  constitutionally arrested and searched him. We can affirm “on

  different grounds than those relied upon by the trial court” if those

  grounds are supported by “undisputed facts in the record.” People

  v. Aarness, 150 P.3d 1271, 1277 (Colo. 2006), as modified on denial

  of reh’g (Jan. 16, 2007). Campbell has not disputed Officer Smidt’s

  testimony with regard to the observed traffic violations, and does

  not assert on appeal that the trial court’s findings of fact on this

  point were clearly erroneous.

¶ 14   The parties initially limited their arguments to whether the

  officers had reasonable suspicion to stop Campbell, which was the

  basis for the trial court’s denial of Campbell’s motion to suppress.

  We requested supplemental briefing from both parties on the issue




                                     7
  of whether the violations observed by Officer Smidt gave rise to

  probable cause to stop and arrest Campbell.

¶ 15   Officer Smidt testified that he observed Campbell turn without

  signaling, a class A traffic infraction under Colorado law. See § 42-

  4-903(2), (5), C.R.S. 2017. We conclude that Officer Smidt’s

  observation of this violation of the traffic code justified the initial

  stop, regardless of whether the description communicated by the

  dispatcher independently created reasonable suspicion sufficient to

  stop the vehicle.

¶ 16   In their supplemental brief, the People further argue that the

  officers had probable cause to believe that Campbell was eluding

  the officers in violation of section 18-9-116.5(1), C.R.S. 2017, a

  class 5 felony. The record supports this contention. In its findings

  of fact, the trial court noted that “it looked like the driver was trying

  to get away from” the officer because the driver did not stop for

  several blocks after the officer first activated his lights and sirens.

  We therefore agree that “the facts and information within the

  arresting officers’ knowledge [we]re sufficient” to cause them to

  believe Campbell was committing the felony of vehicular eluding.

  People v. Bustam, 641 P.2d 968, 972 (Colo. 1982).


                                      8
¶ 17   Because the officers had the right to arrest Campbell for

  vehicular eluding, they had the right to use reasonable force in

  effectuating the arrest, see § 18-1-707(1)(a), C.R.S. 2017, and

  conduct a search of Campbell’s person incident to arrest, see

  Rawlings v. Kentucky, 448 U.S. 98, 111 (1980). Thus, we conclude

  that the trial court did not err in denying Campbell’s motion to

  suppress evidence obtained as a result of his seizure and search.

                   III. Motion to Suppress GPS Data

¶ 18   Campbell asserts that the trial court erred in denying his

  motion to suppress the GPS data obtained from the ankle monitor.

  As an issue of first impression in Colorado, we conclude that,

  because Campbell did not have a reasonable expectation of privacy

  in the GPS location data generated by the ankle monitor under the

  United States or Colorado Constitutions, the trial court did not err.

                            A. Additional Facts

¶ 19   When Campbell was arrested, the officers found a monitor on

  his ankle, which Campbell said he was wearing at the request of a

  private bail bondsman. The officers did not remove the ankle

  monitor.




                                    9
¶ 20   After Campbell’s arrest, Detective George McGlynn contacted

  the GPS monitoring company, Interstate Monitoring Bureau

  Corporation, to request the data generated by the ankle monitor.

  Detective McGlynn did not seek a warrant for this GPS data.

  Rather, Interstate Monitoring voluntarily provided the information

  requested. As explained during trial, the documents provided by

  the monitoring company detailed Campbell’s location every five

  minutes. The records introduced at trial covered over one month of

  Campbell’s whereabouts, totaling 9643 “tracking events” or

  five-minute increments. Based on the records, Detective McGlynn

  determined that Campbell had been at J.P.’s home, as well as two

  other homes when they were burglarized in March and April of

  2012.

¶ 21   In its bench ruling, the trial court concluded that Campbell

  lacked standing to challenge the allegedly unconstitutional search

  of the GPS data. In its findings of fact, the trial court noted that the

  ankle monitor had been imposed “as a condition of bond, whether it

  [was] court ordered or ordered by the bondsman.” The trial court

  reasoned that Campbell was “not asserting his own rights” because,

  even if the bondsman might have an expectation of privacy in the


                                    10
  records maintained by the monitoring company, Campbell did not.

  In light of its conclusion that Campbell lacked standing to contest

  the collection of the GPS data, the trial court denied his motion to

  suppress.

                         B. Standard of Review

¶ 22   In reviewing a ruling on a motion to suppress, we defer to a

  trial court’s findings of fact if they are supported by competent

  evidence in the record. King, 16 P.3d at 812. We review

  conclusions of law de novo. Id.

                           C. Applicable Law

¶ 23   The constitutional protections against unreasonable searches

  and seizures are personal. See Alderman v. United States, 394 U.S.

  165, 174 (1969) (“Fourth Amendment rights are personal rights

  which . . . may not be vicariously asserted.”). To invoke the Fourth

  Amendment’s protections, a defendant must show that “the

  disputed search and seizure has infringed an interest of the

  defendant which the Fourth Amendment was designed to protect.”

  Rakas v. Illinois, 439 U.S. 128, 140 (1978).

¶ 24   While often referred to as an issue of standing, the Rakas

  Court recognized that this threshold question “belongs more


                                    11
  properly under the heading of substantive Fourth Amendment

  doctrine than under the heading of standing.” Id.; see also

  Rawlings, 448 U.S. at 106 (noting that, after Rakas, the standing

  inquiry merged with the substantive question “whether

  governmental officials violated any legitimate expectation of privacy”

  held by the defendant). Thus, a person has “standing” to challenge

  a search “if the defendant maintained a reasonable expectation of

  privacy in the place searched.” People v. Galvadon, 103 P.3d 923,

  930 (Colo. 2005).

¶ 25   To assess whether a defendant had a reasonable expectation

  of privacy in the place searched, we turn to the two-prong test set

  forth in Katz v. United States, 389 U.S. 347, 361 (1967) (Harlan, J.,

  concurring). People v. Gutierrez, 222 P.3d 925, 932 (Colo. 2009).

  Under that test, “[a] defendant must have an actual expectation

  that the area or activity subjected to governmental intrusion would

  remain free of such intrusion and such an expectation must be one

  that ‘society is prepared to recognize as reasonable.’” Galvadon,

  103 P.3d at 929 (quoting People v. Oates, 698 P.2d 811, 814 (Colo.

  1985)).




                                    12
¶ 26   In a line of cases, the United States Supreme Court has held

  that a person has no reasonable expectation of privacy in

  information he or she voluntarily discloses to a third party. See

  Smith v. Maryland, 442 U.S. 735, 742-43 (1979); United States v.

  Miller, 425 U.S. 435, 443 (1976); Hoffa v. United States, 385 U.S.

  293, 302 (1966). Thus, “the Fourth Amendment does not prohibit

  the obtaining of information revealed to a third party and conveyed

  by him to Government authorities.” Miller, 425 U.S. at 443. This is

  true “even if the information is revealed on the assumption that it

  will be used only for a limited purpose and the confidence placed in

  the third party will not be betrayed.” Id.

¶ 27   The Colorado Supreme Court, however, has held that article II,

  section 7 of the Colorado Constitution encompasses a “broader

  definition of what constitutes a legitimate expectation of privacy

  from government intrusion than that of its federal counterpart.”

  Galvadon, 103 P.3d at 927. Thus, the Colorado Supreme Court

  held that a bank customer had a reasonable expectation of privacy

  in his bank records under the Colorado Constitution, despite

  Supreme Court precedent that no reasonable expectation of privacy

  in such records exists under the Fourth Amendment. Charnes v.


                                    13
  DiGiacomo, 200 Colo. 94, 98-100, 612 P.2d 1117, 1119-21 (1980)

  (discussing and declining to follow Miller, 425 U.S. 435); cf.

  Gutierrez, 222 P.3d at 935 (finding third party doctrine inapplicable

  and holding that taxpayers have reasonable expectation of privacy

  in income tax returns even when they disclose them to the Internal

  Revenue Service, the state department of revenue, and tax

  preparers). Similarly, the Colorado Supreme Court has held that

  telephone users have a reasonable expectation of privacy in the

  numbers they dial, despite the Supreme Court’s holding to the

  contrary. People v. Sporleder, 666 P.2d 135, 142 (Colo. 1983)

  (discussing and declining to follow Smith, 442 U.S. 735).

                               D. Analysis

¶ 28   To begin, we address the first prong of Katz, under which a

  defendant must have an actual expectation of privacy in the place

  searched. Campbell urges that he maintained a subjective

  expectation that the GPS data generated by his ankle monitor

  would not be exposed or otherwise subjected to “public scrutiny.”

¶ 29   As support for this assertion, he notes that the monitoring

  company stored the data “in a web-based secured interface.”

  Further, Campbell asserts that, because he wore the ankle monitor


                                    14
  at the request of a private bail bondsman, he believed the sole

  purpose of the GPS monitoring was to ensure that he did not

  abscond from the state and thereby fail to appear in court. He did

  not anticipate that the data would be used “to facilitate criminal

  investigations.” We assume without deciding that Campbell had an

  actual, subjective expectation of privacy in the GPS data. See

  Gutierrez, 222 P.3d at 932 (deferring to trial court’s finding that the

  defendant had a subjective expectation of privacy in tax returns

  where tax preparer kept the records in a secure cabinet).

¶ 30   Nevertheless, we conclude under the second prong of Katz that

  any expectation of privacy in the GPS data was not “one that society

  is prepared to recognize as ‘reasonable.’” Katz, 389 U.S. at 361

  (Harlan, J., concurring). Campbell asserts that “other jurisdictions

  have held that GPS location data implicates an individual’s privacy

  interest.” However, the cases he cites in support of that argument

  involved circumstances in which law enforcement agents

  surreptitiously installed GPS tracking devices on individuals’

  vehicles without obtaining warrants. See, e.g., United States v.

  Jones, 565 U.S. 400 (2012). Campbell correctly asserts that those

  cases generally acknowledge the “unique attributes of GPS


                                    15
  surveillance.” Id. at 415 (Sotomayor, J., concurring). Certainly,

  several courts have recognized that long-term GPS monitoring

  “generates a precise, comprehensive record of a person’s public

  movements that reflects a wealth of detail about her familial,

  political, professional, religious, and sexual associations.” Id.

¶ 31   However, the cases cited by Campbell do not address the

  precise issue here — whether a defendant has a reasonable

  expectation of privacy in GPS location data transmitted to and

  collected by a third party. Under the Supreme Court precedent,

  Campbell had no reasonable expectation of privacy in the GPS data

  because he voluntarily disclosed such data to a third party — his

  bondsman. Campbell was aware that his bondsman had access to

  the GPS location data to ensure that he did not leave the state while

  out on bond. In short, Campbell “t[ook] the risk, in revealing his

  affairs to another, that the information w[ould] be conveyed by that

  person to the Government.” Miller, 425 U.S. at 443. Thus, even if

  we assume he subjectively believed his GPS data would remain

  private, that expectation was not one society would be prepared to

  call reasonable.




                                    16
¶ 32   We reach the same result even under the broader protections

  afforded by the Colorado Constitution. In Charnes v. DiGiacomo,

  the supreme court distinguished Miller, 425 U.S. 435, by noting

  that a bank customer does not truly voluntarily disclose

  information about his or her financial transactions because bank

  accounts are necessary in modern life and because the customer’s

  primary purpose in having a bank account is facilitating the

  transfer of funds. 200 Colo. at 99, 612 P.2d at 1121 (discussing

  and following Burrows v. Superior Court, 529 P.2d 590 (Cal. 1974)).

  In contrast, here, Campbell chose to contract with the private bail

  bondsman and knew that the primary purpose of the ankle monitor

  was to track and record his location. Further, Campbell could not

  reasonably have anticipated that the GPS data would remain “free

  from governmental intrusion,” Sporleder, 666 P.2d at 140, when the

  bail bondsman could have reported his location to the court had he

  absconded in violation of his bond terms.

¶ 33   Accordingly, we conclude that Campbell cannot invoke the

  protections of either the Fourth Amendment of the United States

  Constitution or article 2, section 7 of the Colorado Constitution

  because he had no reasonable expectation of privacy in the GPS


                                   17
  data. Thus, the trial court did not err in denying his motion to

  suppress.

                     IV. Admissibility of GPS Data

¶ 34   Campbell next contends that the trial court erred in admitting

  the GPS evidence without first holding a hearing to assess its

  reliability pursuant to People v. Shreck, 22 P.3d 68 (Colo. 2001).

  We disagree.

                           A. Additional Facts

¶ 35   Before trial, Campbell moved for a Shreck hearing on the

  admissibility of the GPS records and any expert testimony relating

  to that data. Campbell asserted that a hearing was necessary to

  assess the reliability of the evidence because Interstate Monitoring

  was not obligated to test the ankle monitor devices or ensure their

  accuracy, and because GPS technology is “fairly new.”

¶ 36   In denying the motion for the Shreck hearing, the trial court

  stated that “GPS has been around for a long time.” The trial court

  therefore concluded that “this is not the type of new and novel

  scientific evidence” that must be vetted by a pretrial evidentiary

  hearing.




                                    18
¶ 37   During trial, Bruce Derrick testified as an expert in GPS

  devices and technology. Derrick worked for SecureAlert, the

  manufacturer of the ankle monitor Campbell was wearing when

  arrested. He testified how GPS devices communicate location data

  to a monitoring center, as well as the specific mechanics of the

  ankle monitor device. Defense counsel cross-examined Derrick at

  length on the accuracy of GPS location data.

                         B. Standard of Review

¶ 38   We review a trial court’s evidentiary ruling for an abuse of

  discretion. People v. Veren, 140 P.3d 131, 136 (Colo. App. 2005). A

  trial court abuses its discretion when its ruling is “manifestly

  arbitrary, unreasonable, or unfair.” Id.

¶ 39   We review any error in denying a Shreck hearing under the

  nonconstitutional harmless error standard. People v. Wilson, 2013

  COA 75, ¶ 24, 318 P.3d 538, 543. Under this standard, we will

  reverse only if the error “substantially influenced the verdict or

  affected the fairness of the trial proceedings.” Hagos v. People,

  2012 CO 63, ¶ 12, 288 P.3d 116, 119 (quoting Tevlin v. People, 715

  P.2d 338, 342 (Colo. 1986)).

                            C. Applicable Law


                                    19
¶ 40   CRE 702 governs the admissibility of scientific evidence as

  well as expert testimony. Shreck, 22 P.3d at 77. A trial court’s

  determination as to scientific evidence’s admissibility should be

  “broad in nature” and flexible, with the ultimate goal of assessing

  whether the evidence is relevant and reliable. Id. A trial court

  assesses whether scientific evidence and related expert testimony

  are admissible by considering whether (1) the scientific principles

  underlying the expert’s testimony are reliable; (2) the expert is

  qualified to give an opinion on the subject; (3) the testimony will be

  helpful to the jury; and (4) the probative value of the testimony is

  substantially outweighed by the danger of unfair prejudice. See id.

  at 77-79; see also People v. Rector, 248 P.3d 1196, 1200 (Colo.

  2011).

¶ 41   Once a party requests that evidence be subjected to a Shreck

  analysis, the trial court can, in its discretion, hold an evidentiary

  hearing on the matter. Wilson, ¶ 23, 318 P.3d at 543. However, the

  trial court is not required to conduct an evidentiary hearing if it

  “already has sufficient information to make specific findings under

  Shreck.” Id.




                                     20
¶ 42     Concerns about conflicting theories or the reliability of

  scientific principles go to the weight of the evidence, not its

  admissibility. See Estate of Ford v. Eicher, 250 P.3d 262, 269 (Colo.

  2011). Such concerns “are adequately addressed by vigorous

  cross-examination, presentation of contrary evidence, and careful

  instruction on the burden of proof.” Id. (citing Shreck, 22 P.3d at

  78).

                                D. Analysis

¶ 43     We conclude that the trial court did not abuse its discretion in

  denying Campbell’s motion for a pretrial hearing on the

  admissibility of the GPS data. GPS technology is prevalent in

  modern society and widely regarded as reliable. “Courts routinely

  rely on GPS technology to supervise individuals on probation or

  supervised release, and, in assessing the Fourth Amendment

  constraints associated with GPS tracking, courts generally have

  assumed the technology’s accuracy.” United States v. Brooks, 715

  F.3d 1069, 1078 (8th Cir. 2013). Indeed, the concurrence in Jones

  acknowledged that GPS technology in modern cell phones “permit[s]

  more precise tracking” than previous technology allowed. Jones,

  565 U.S. at 428 (Alito, J., concurring in the judgment). The


                                      21
  overarching concern of any Shreck analysis is the reliability and

  relevance of the scientific evidence, and we conclude, like other

  courts, that GPS evidence is sufficiently reliable to satisfy CRE 702.

¶ 44   We realize that Colorado’s standard for the admissibility of

  scientific evidence differs from the test laid out in Daubert v. Merrell

  Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993), and that other

  state rules of evidence may differ from CRE 702. Nevertheless, we

  find it instructive to consider the admissibility of GPS evidence in

  other jurisdictions which have held that GPS evidence is reliable

  and, thus, admissible. See Brooks, 715 F.3d at 1078 (affirming

  district court’s taking judicial notice of “the accuracy and reliability

  of GPS technology,” and thus allowing GPS evidence without expert

  testimony); United States v. Mathews, 250 F. Supp. 3d 806, 819 (D.

  Colo. 2017) (denying the defendant’s motion for a Daubert hearing

  on GPS data and stating that the defendant’s challenge to the

  accuracy of the GPS data was “a matter for cross-examination”);

  Brown v. State, 163 S.W.3d 818, 824 (Tex. App. 2005) (holding GPS

  records sufficiently reliable); see also James Beck et al., The Use of

  Global Position System (GPS) and Cell Tower Evidence to Establish a

  Person’s Location, 49 No. 1 Crim. L. Bull. art. 7 (Winter 2013) (“The


                                     22
  relatively unchallenged science behind GPS and the extensive,

  successful reliance on the technology during the past 30 years

  justify its admissibility in court.”); cf. United States v. Thompson,

  393 F. App’x 852, 859 (3d Cir. 2010) (allowing a lay witness “to

  testify concerning the operation of [a] GPS device”).

¶ 45   In any event, here, Derrick was properly qualified to testify as

  an expert on GPS technology. Campbell conducted voir dire of

  Derrick and thoroughly cross-examined him on the accuracy of GPS

  technology generally and the ankle monitor device specifically.

¶ 46   In light of the reliability of GPS evidence, we conclude that the

  trial court did not err in denying Campbell’s motion for a pretrial

  Shreck hearing.

                    V. Motion to Suppress Identification

¶ 47   Campbell’s final contention is that the trial court erred in

  denying his motion to suppress J.P.’s identification. He asserts

  that, because the out-of-court identification procedure was unduly

  suggestive and unreliable, admission of J.P.’s in-court identification

  violated his constitutional due process rights. We disagree.




                                     23
                           A. Additional Facts

¶ 48   J.P. encountered Campbell in the stairway of his house. The

  victim had just woken up when he heard noises downstairs, and he

  was not wearing his contact lenses or eyeglasses. It was

  midmorning and the house was well lit. The two men were

  approximately ten feet away from each other for one or two seconds

  before Campbell ran out of the house. During the 911 call, the

  victim described Campbell as a black male, about 5’8” or 5’9” tall,

  wearing a dark gray or black hoodie, dark jeans, and white

  sneakers.

¶ 49   When officers stopped Campbell’s car, the victim was still on

  the line to the 911 dispatcher. The dispatcher told him that officers

  had pulled over a vehicle matching the description he had given.

  Shortly after the 911 call ended, an officer took the victim to the

  location where Campbell had been pulled over.

¶ 50   When the victim got to the scene of Campbell’s arrest, there

  were four or five police vehicles, two police motorcycles, and more

  than eight police officers present. There were no other people aside

  from Campbell and the victim. When the victim was driven to the




                                    24
  scene, Campbell was seated in the backseat of a police vehicle in

  handcuffs. Campbell was the only black person at the scene.

¶ 51   The victim testified that he “knew almost immediately” that

  Campbell had been the man who broke into his home. An officer

  told him to “slow down [and] make sure.” After another minute or

  so, the victim again positively identified Campbell. The victim was

  wearing eyeglasses during the show-up identification, though he

  later testified that his uncorrected vision was “not bad” and he

  merely preferred to have eyeglasses on.

¶ 52   The trial court found that the show-up procedure utilized by

  the officers here was suggestive. However, the trial court

  nonetheless denied Campbell’s motion to suppress the out-of-court

  identification because it found that the identification was reliable

  under the totality of the circumstances.

                         B. Standard of Review

¶ 53   We review a trial court’s determination on the admissibility of

  an identification as a mixed question of fact and law, affording

  deference to the findings of fact and reviewing the legal conclusions

  de novo. See Bernal v. People, 44 P.3d 184, 190 (Colo. 2002).




                                    25
¶ 54   We review preserved errors of constitutional dimension for

  constitutional error, meaning we will reverse unless the People

  show that the error was harmless beyond a reasonable doubt.

  Hagos, ¶ 11, 288 P.3d at 119.

                            C. Applicable Law

¶ 55   In considering a challenge to an out-of-court identification, a

  court must follow a two-step analysis. Bernal, 44 P.3d at 191.

  First, a defendant must prove that the identification procedure was

  unduly suggestive. See id. If the defendant shows the procedure

  was impermissibly suggestive, the burden then shifts to the People

  to show that the identification was nevertheless reliable under the

  totality of the circumstances. Id.

¶ 56   Under the second step of this analysis, the court may consider

  several factors, including “(1) the opportunity of the witness to view

  the criminal at the time of the crime; (2) the witness’s degree of

  attention; (3) the accuracy of the witness’s prior description of the

  criminal; (4) the level of certainty demonstrated by the witness at

  the confrontation; and (5) the length of time between the crime and

  the confrontation.” Id. at 192. Ultimately, the suggestiveness of the

  identification procedure must be balanced against the indicia of


                                       26
  reliability; provided that there is not a “very substantial likelihood of

  irreparable misidentification,” the identification is admissible. Id.;

  see also People v. Weller, 679 P.2d 1077, 1083 (Colo. 1984).

                                D. Analysis

¶ 57   The trial court found, Campbell argues, and the People do not

  contest that the show-up procedure utilized here was impermissibly

  suggestive. We agree. When the victim arrived at the scene of

  Campbell’s arrest, Campbell was handcuffed in the back of a police

  vehicle surrounded by officers and he was the only black person

  present. Moreover, the dispatcher told the victim that officers had

  pulled over a vehicle matching his description. This show-up

  procedure was impermissibly suggestive. See generally Weller, 679

  P.2d at 1083 (“One-on-one showups are not favored and tend to be

  suggestive.”).

¶ 58   Nevertheless, we conclude that the People met their burden of

  proving that the identification was reliable despite the suggestive

  procedure. With regard to the first factor set forth in Bernal, the

  victim had the opportunity to see the intruder for one or two

  seconds in a well-lit area while the two men were about ten feet

  away from one another. Moreover, the victim testified that,


                                     27
  although he was not wearing contact lenses or eyeglasses, he felt he

  was able to see the intruder sufficiently to later identify him. As for

  the second factor, the trial court concluded that the victim was

  startled when he encountered the intruder, which heightened his

  degree of attention, and we defer to this finding.

¶ 59   The third factor –– the accuracy of the witness’ description ––

  weighs less in favor of the People. The victim’s description of the

  intruder was somewhat generic, and there were inconsistencies

  between the description provided to the 911 dispatcher and

  Campbell’s actual appearance. However, looking to the fourth

  factor, the victim’s confidence in the identification was high. He

  quickly confirmed that Campbell was the intruder once on the

  scene, and he later testified that he was ninety-five percent sure his

  identification was accurate. He was also “very positive” on the

  color, make, and model of the car that he saw driving away from his

  home. Finally, the time between the crime and confrontation was

  extremely brief. The identification occurred less than an hour after

  the victim first saw the intruder.

¶ 60   In sum, especially in light of the strength of the final two

  factors, we conclude that the identification was reliable despite the


                                       28
  suggestiveness of the procedure. We cannot say that, given the

  totality of the circumstances, there was a “very substantial

  likelihood of irreparable misidentification.” Bernal, 44 P.3d at 192.

  As a result, we conclude the trial court did not err in denying the

  motion to suppress the identification.

                             VI. Conclusion

¶ 61   Accordingly, the judgment is affirmed.

       JUDGE FURMAN and JUDGE RICHMAN concur.
