Authentication of Map of Locations Based on Cell Phone Signals to Towers — Expert Testimony re Technology Plus Circumstantial Evidence Linking Phones to Owners at Relevant Times — Use of Names vs. Phone Numbers on Exhibit Upheld
United States v. Reed, 780 F.3d 260 (4th Cir. 2015):
Four masked men committed a string of robberies around Alexandria and Arlington, Virginia, in December 2012. During the third and final robbery, the thieves took $60,411.15 from a credit union. [**2] They also unwittingly took three GPS tracking devices embedded in the cash. The GPS devices led police to the four appellants in this case: Keith Reed, Stanley Winston, Anthony Cannon, and Tobias Dyer (collectively, "Appellants"). Appellants were ultimately convicted at a jury trial for multiple offenses. In this consolidated appeal, Appellants challenge the admission of certain evidence and claim that there is insufficient evidence to convict them for any of the charged crimes. For the reasons stated below, we affirm their convictions.
At trial the government proffered evidence, viewed in the light most favorable [*264] to the government's case, that supports the following narrative. United States v. Hassan, 742 F.3d 104, 139 (4th Cir. 2014).
At approximately 8:04 p.m. on December 7, 2012, three African American men entered the premises of VVM, Inc., a business that sells cell phones and international phone cards in Alexandria, Virginia. When the men entered, a VVM employee was serving a customer. The men--wearing ski masks and brandishing firearms--ordered the employee and customer to the floor and demanded that they not move. After unsuccessfully trying to breach a closed Western Union office that shared the premises with VVM, the men grabbed [**3] approximately $800 from the VVM cash register. They then fled in a Jeep driven by a fourth accomplice. Police recovered a Jeep the next morning, approximately a half mile from the VVM store. The Jeep, which had been reported stolen, was damaged from a punched-in ignition, and the last four numbers of its license plate matched those provided by a witness to the VVM robbery.
Camera footage of the robbery, along with witness testimony, revealed that two of the robbers who entered VVM were tall (approximately six feet), while the third was shorter (approximately five feet, six inches). Two of the appellants--Cannon and Dyer--are six feet tall, while Winston is shorter at approximately five feet, six inches. Moreover, all the appellants are African American.
Cell-phone records show that Appellants had called each other numerous times throughout the day of the robbery. There were no calls between them after 6:00 p.m., however, implying that they were together by that point. Phone records also show Appellants had traveled to Alexandria by 6:30 p.m., were near VVM at 8:00 p.m., and had returned to their hometown of Washington, D.C., by 8:13 p.m. (just after the robbery), where they remained [**4] for the rest of the night.
Two days later, on December 9 at approximately 6:30 a.m., three masked men brandishing firearms entered a Shoppers Food Warehouse in Alexandria, while a fourth man waited in a Jeep outside. The robbers who entered the store were African American, and again two of them were tall while the third was shorter. One tall robber climbed a wall into a manager's office, while the other two ordered employees and a customer to the ground while the robbers took money from cash registers. The robbers fled the store with $15,695. Later that day, some of the appellants used their phones to take pictures of stacks of cash and themselves celebrating at a club. Police found a stolen Jeep, which was also damaged from a punched-in ignition, a week later in D.C. In the Jeep's trunk, officers recovered cash tills containing receipts from the Alexandria Shoppers Food Warehouse.
Phone records again show that Appellants (primarily Dyer and Reed) made numerous calls to each other during the day of the robbery--this time in the early morning from midnight to 5:21 a.m. These records also show that although Reed, Cannon, and Dyer were all in D.C. before 5:30 a.m., at least Reed and Cannon [**5] were in Alexandria and near the Shoppers Food Warehouse by 6:15 a.m.--only 15 minutes before the robbery.
Two weeks later, on December 22 at approximately 9:50 a.m., three masked men entered a Navy Federal Credit Union ("the Credit Union") in Arlington, Virginia, [*265] while a fourth waited in a Jeep outside. Once again, two of the robbers were tall, the other short. The short robber demanded money near the Credit Union's main entrance. The tall robbers--one of whom had a semi-automatic handgun with a drum-style magazine--jumped over the teller counter. One robber filled a trash can with money from the teller drawer, while another went to the Credit Union's vault, where he took money and cash bags. The robbers fled with $60,411.15 and--unbeknownst to them--three GPS tracking devices hidden in the cash. A stolen Jeep matching the description of the escape vehicle was found later, again damaged with a punched-in ignition. In addition, the officers recovered a trash can in the Jeep's front passenger area, similar to one the Credit Union robbers had reportedly used to transport the stolen bags of money.
Phone records show that Dyer, Winston, and Reed called each other several times in the hours [**6] before the robbery. Although they were all in D.C. during the early morning, records show that at least Winston was in Arlington near the Navy Federal Credit Union by 9:32 a.m.--approximately 18 minutes before the robbery.
Law enforcement tracked the GPS signals to an area in southeast D.C. A police officer canvassed the area for four to six males. The officer saw Appellants walking on the street. One of the men left the group to drop a blue bag--later found to contain a hoodie and ski mask--across the street and then returned to the group. The officer asked the group whether they lived nearby and requested that they present identification. Reed then fled into woods, and the others followed.
Additional police officers arrived and joined in the pursuit. The officers apprehended each appellant one by one. When the officers spotted Reed, he had a blue cell phone in his hand and appeared to be talking on it. Despite orders to keep his hands up, Reed kept dropping his hands. When officers approached, an officer saw the phone and a black ski mask near Reed. Another officer detained Reed and placed his belongings (including the cell phone) in a property bag, which was transported to a police [**7] station.1 The police also transported a bag labeled "Dyer" containing an iPhone 5 to the police station, although at trial the government offered no testimony about how this phone was seized. Officers found masks, money, and gloves strewn on the ground throughout the woods where Appellants were arrested.
1 It was standard practice for officers to place an arrestee's personal effects in a property bag labeled with the arrestee's name. FBI Special Agent Mark Hess later collected all the bags from the police station.
After Appellants were apprehended, police found that the third GPS tracker was emitting signals from Cannon's residence. In that house, police found three ski masks, two pairs of black gloves, thousands of dollars in cash, the third GPS tracker, and three firearms (including one with a drum-style magazine). In total, officers seized eight masks, which analysts found contained DNA consistent with Appellants' DNA.
On April 23, 2013, a federal grand jury indicted Reed, Winston, Cannon, and Dyer on 12 counts stemming from the three robberies: conspiracy to commit Hobbs Act2 robbery (Count 1); Hobbs Act robbery [*266] (Counts 2 through 4, for each robbery); armed robbery of a credit union [**8] (Count 5); using, carrying, and brandishing a firearm during and in relation to a crime of violence (Counts 6 through 8, for each robbery); and being a felon-in-possession of a firearm (Counts 9 through 12, for each appellant). After a four-day trial, a jury convicted Appellants on all counts. Winston and Cannon filed separate motions for judgment of acquittal, which were denied. The district judge sentenced each of the appellants to 720 months (60 years) in prison.
2 Hobbs Act, 18 U.S.C. § 1951.
Appellants contest their convictions on several grounds. First, they argue that the trial judge abused his discretion and violated the Federal Rules of Evidence by admitting certain evidence. Similarly, but separately, Dyer claims that admitting evidence recovered from his cell phone violated the Sixth Amendment because the government failed to offer any testimony establishing how the phone was seized. Finally, Appellants argue that there is insufficient evidence to sustain their convictions. We assess each argument below.
Appellants first challenge the trial court's admission of Exhibit 45, a collection of maps produced by the FBI Cellular Analysis Detail Team and proffered by the government at trial. The FBI produced [**9] the maps using data from Appellants' cell phones and their service providers' cell towers. As explained at trial, a cell phone communicates with towers (usually the tower closest to the phone) when a person sends a text, makes or receives a voice call, or uses cellular data. Service providers record these communications. From these records, the FBI can extrapolate a probable area in which the phone was located over time. This process is known as a historical cell-site analysis. In this case, the cell-site analysis from Appellants' phone data placed at least one of the appellants near the scene of each robbery, close in time to when the robbery occurred.3
3 For example, Reed's phone data showed that he was in Washington, D.C. around 6:05 p.m. on December 7, 2012, but near Alexandria and the VVM store a mere 20 minutes later. His phone contacted a phone tower in Alexandria again around 8:04 p.m.--the time of the robbery. A mere ten minutes after the robbery occurred, Reed's phone contacted a tower back in D.C., suggesting that he quickly returned to D.C. after committing the VVM robbery.
On appeal, Appellants challenge the government's use of their names, rather than phone numbers, when showing [**10] the phones' locations on the maps in Exhibit 45. For example, the map indicated that it was detailing Cannon's possible location at 8:12 p.m. on December 7, 2012, rather than showing the whereabouts of the phone associated with the number 202.510.4853. The government expert testified before the jury that this labeling would be erroneous for a certain defendant if the defendant did not in fact possess the cell phone. Although Appellants make several different arguments under the Federal Rules of Evidence for why the trial judge abused his discretion in admitting Exhibit 45, all the arguments lack merit.
We review the trial court's admission of Exhibit 45 for abuse of discretion. United States v. Mouzone, 687 F.3d 207, 216 (4th Cir. 2012). In other words, we look to see whether the evidentiary ruling was "arbitrary and irrational." Hassan, [*267] 742 F.3d at 130 (quoting United States v. Cole, 631 F.3d 146, 153 (4th Cir. 2011)).
Appellants first argue that the government failed to authenticate Exhibit 45 under Rule 901(a) of the Federal Rules of Evidence. See Fed. R. Evid. 901(a) ("[T]he proponent must produce evidence sufficient to support a finding that the item is what the proponent claims it is."). A proponent can authenticate an item through various means, including "[t]estimony that an item is what it is claimed to be" or "[t]he appearance, contents, substance, internal patterns, or other distinctive characteristics [**11] of the item, taken together with all the circumstances." Fed. R. Evid. 901(b)(1), (4). "[T]he burden to authenticate under Rule 901 is not high," as a "district court's role is to serve as gatekeeper in assessing whether the proponent has offered a satisfactory foundation from which the jury could reasonably find that the evidence is authentic." Hassan, 742 F.3d at 133 (quoting United States v. Vidacak, 553 F.3d 344, 349 (4th Cir. 2009)).
Notwithstanding Appellants' assertion to the contrary, the district court did not violate Rule 901 by admitting Exhibit 45. The government provided adequate reason for the jury to believe (i) that phone data could be used to approximate the phones' location at pertinent times and (ii) that each phone number was associated with a certain appellant. First, as to providing a foundation for the technical aspects of the cell-site analysis, the government's expert, Agent Kevin Horan of the FBI Cellular Analysis Detail Team, detailed how he conducts a cell-site analysis and how it reveals the area in which a phone is likely located at a certain time. See J.A. 703-04, 710-18. This testimony provided a foundation for how the maps were created and allowed the jury to conclude that the maps reflected the phones' locations.
Second, the government proffered evidence that the jury could use [**12] to attribute each phone to one of the four appellants. The government tied the phone with number 202.339.9022 to Dyer through photos of Dyer on the phone and text messages attributing the number to Dyer, including several that used variations on his first name, Tobias. See J.A. 650-52; S.J.A. 77 ("Tfoool"), 88 ("Tobb"), 120 ("UNCLE TOBYYY"), 123 ("Tobias"), 124 ("Tobias"), 125 ("Toby"), 127 ("Sup love dis Toby"), 131-70. The government tied 202.594.4127 to Stanley Winston through a text message that identified the owner as "Stanley" and testimony that Winston handled the phone at issue and assisted the officers in searching the phone. J.A. 481-82; S.J.A. 97. The government tied 240.355.8256 to Reed through testimony of Officer Harry Singleton, who said that he had seen Reed talking on the associated blue phone, which was recovered near where Reed was apprehended. J.A. 234-35, 237-38; see also J.A. 240-41 (describing how Reed's property was collected). And finally, the government tied 202.510.4853 to Cannon, despite no phone being found, through the labeling of that number in Winston's phone as "Cannon." See S.J.A. 93, 97. Based on this testimony and the phones' data, the government [**13] provided a foundation to authenticate each phone as belonging to a certain appellant. Thus, the trial court's admission of Exhibit 45 did not violate Rule 901(a).
Second, Appellants argue that Exhibit 45 was irrelevant under Rule 401 of the Federal Rules of Evidence. Rule 401 provides that "[e]vidence is relevant if: (a) it has any tendency to make a fact more or less probable than it would be without the [*268] evidence; and (b) the fact is of consequence in determining the action." The "fact" at issue here is whether Appellants committed the robberies. Put simply, Exhibit 45 shows Appellants' proximity to the scenes of the robberies close to the times the robberies occurred, as well as Appellants' respective proximity to one another on the days of the robberies. This evidence makes it more probable that they committed the robberies. Thus, Exhibit 45 was plainly relevant under Rule 401.
Finally, Appellants argue that Exhibit 45 was unfairly prejudicial, confused the issues, and misled the jury under Rule 403 of the Federal Rules of Evidence. Rule 403 provides that a "court may exclude relevant evidence if its probative value is substantially outweighed by a danger of . . . unfair prejudice, confusing the issues, [or] misleading the jury." We employ a "highly deferential" standard of review, in which a "decision [**14] to admit evidence over a Rule 403 objection will not be overturned except under the most extraordinary circumstances, where that discretion has been plainly abused." Hassan, 742 F.3d at 132 (quoting United States v. Udeozor, 515 F.3d 260, 265 (4th Cir. 2008)).
Appellants' argument is based on Exhibit 45 (i) purportedly not being drawn to scale and (ii) using Appellants' names rather the phones' numbers as labels. As to whether Exhibit 45's scale caused unfair prejudice or misled the jury, Appellants rely on bare conclusions. Thus, they have failed to show that the maps in Exhibit 45 were in fact not drawn to scale or that the scale caused any unfair prejudice.
Appellants' argument regarding the use of their names rather than the phones' numbers is somewhat stronger, but likewise without merit. As Appellants correctly note, for the labeling to be accurate, the jury was required to conclude that each appellant in fact possessed the phone attributed to him. Appellants argue that the use of names, not numbers, usurped the jury's prerogative to make this determination. The record, however, shows otherwise. Indeed, the government's expert and Appellants' counsel repeatedly noted at trial (i) that Exhibit 45 was not dispositive of whether Appellants in fact possessed the phones and [**15] (ii) that the use of names would be inaccurate if the government mistakenly attributed the phones to Appellants. See, e.g., J.A. 713, 715-18, 734-35, 742-45, 829-30, 835, 849. This testimony mitigated any likelihood of unfair prejudice, confusing the issues, or misleading the jury. Therefore, any prejudice from using names rather than numbers does not substantially outweigh Exhibit 45's probative value, and the trial judge did not abuse his discretion in admitting the evidence.
