TOBIAS DIGGS, Defendant-Appellant.

Appeal from the United States District Court for the Northern District of Illinois, Eastern Division. No. 1:18-cr-185-1 — Gary Feinerman, Judge.

ARGUED JANUARY 10, 2023 — DECIDED SEPTEMBER 5, 2023

Before SCUDDER, KIRSCH, and JACKSON-AKIWUMI, Circuit Judges.

KIRSCH, Circuit Judge. A jury convicted Tobias Diggs of armed robbery and other associated crimes after he and three others held up an Illinois jewelry store. Two evidentiary rulings form the basis of Diggs’s appeal. First, Diggs argues that the district court should not have permitted his wife to testify against him. The district court concluded that she was a co- conspirator, so the spousal testimonial privilege did not 2 No. 22-1502

apply. Second, Diggs argues that certain hearsay testimony from the case agent should have resulted in a mistrial. But any evidentiary error was harmless, and the district court did not abuse its discretion in refusing to grant a mistrial, so we affirm .

I

A jury found that Tobias Diggs and three others robbed the Razny Jewelers store in Hinsdale, Illinois, on March 17, 2017. At trial, the government’s evidence established that when the store opened at 10 am, Diggs and two others exited a blue Lexus SUV bearing Michigan license plates. They entered the store with guns raised and equipped with handcu ffs, sporting masks, and gloves. They quickly subdued and handcuffed the store’s security guard and dragged a sales associate to a back room where they handcuffed and pistolwhipped her. One of the men encountered another sales associate , put a gun to her head, locked her in the bathroom, and told her he’d kill her if she tried to get out. A fourth man in the crew, Joshua McClellan, sat in the Lexus and listened to the robbery unfold on his cellphone before driving the men— and their haul of more than $400,000 in watches and jewelry— to temporary safety. Three days later, Diggs and McClellan drove from Chicago to Atlanta to liquidate their haul. They met with a jeweler—A.P. the Jeweler—who initially expressed interest but eventually demurred due to the asking price. After returning to Chicago, McClellan found a willing buyer.

Eventually, the law caught up with Diggs and McClellan. (Marvon Hamberlin and the fourth man remain at large.) A grand jury indicted the pair on charges of Hobbs Act robbery, conspiring to do the same, brandishing a firearm during a

crime of violence, and transporting stolen goods. Diggs and McClellan pleaded not guilty and were tried together. The jury convicted both men on all counts. Diggs preserved his two challenges, which we turn to now.

II

Before trial, Diggs informed the court that his wife, Devinn Adams (who was his girlfriend at the time of the robbery), would invoke the spousal testimonial privilege if called to testify . The district court denied the privilege on the grounds that Adams fell within the joint-participant exception. See United States v. Clark, 712 F.2d 299, 301 (7th Cir. 1983) (no spousal testimonial privilege when the defendant and spouse jointly participated in the criminal conduct). The district court found that the government’s proffered evidence showed that Adams became a co-conspirator on the day of the robbery and only withdrew a few days later when she told police that Diggs had used her car for the robbery. The district court concluded that the joint participant exception deprived Adams of spousal testimonial privilege.

On appeal, Diggs argues that we should reconsider and reject our joint-participant exception to the spousal testimonial privilege. Failing that, Diggs contends that Adams wasn’t a joint participant, so the district court erred by compelling her to testify.

We need not reach these arguments, however. Like all evidentiary objections, the district court’s finding that Adams was a joint participant is subject to the harmless error standard . The government carries the burden of proving that an error was harmless, meaning that it did not affect a defendant’s substantial rights. United States v. Gomez, 29 F.4th 915, 929 (7th 4 No. 22-1502

Cir. 2022). When considering a non-constitutional error like the one Diggs alleges, if we “cannot say, with fair assurance, after pondering all that happened without stripping the erroneous action from the whole, that the judgment was not substantially swayed by the error, it is impossible to conclude that substantial rights were not affected.” Kotteakos v. United States, 328 U.S. 750, 765 (1946). In other words, we ask “whether an average juror would find the prosecution’s case significantly less persuasive without the improper evidence.” United States v. Miller, 673 F.3d 688, 701 (7th Cir. 2012). We consider the impact of the improperly admitted evidence on the minds of the jury, “not singled out and standing alone, but in relation to all else that happened.” Kotteakos, 328 U.S. at 764. Here, after considering Adams’s testimony (and its role in the government’s case) in relation to “all else that happened” at trial, we are convinced that an average juror would not find the government’s case significantly less persuasive without it.

Department of Homeland Security Special Agent Daniel Silk led the investigation into the robbery and offered ample testimony and evidence to support Diggs’s guilt. He testified that in early 2017, McClellan’s calls and text messages suggested that he and Diggs worked to surveil a robbery target and coordinate their activities. McClellan’s phone records and Diggs’s social media accounts, cell-site location information (CSLI), and toll records all linked Diggs to a cellphone number that had been activated a week before the robbery.

At trial, Diggs argued unsuccessfully that the phone number didn’t belong to him, but the evidence that it did was overwhelming. Diggs sent a social media message asking someone to call him at that number. Diggs received a

No. 22-1502 5

Facebook message asking him to place a call, and toll records reflect the call was made from that number just minutes later. The contacts list on McClellan’s phone associated the number with Diggs. Cell-site records showed that the number most frequently used the cell tower nearest to Diggs’s home. Toll records showed dozens of text messages and calls to numbers associated with Diggs’s family, his two girlfriends (Adams and another woman named Jessica Christian), McClellan, and an individual called Gold Mouth. On appeal, Diggs does not challenge that the phone number belonged to him.

Phone records from the day of the robbery revealed that Diggs, McClellan, and the two others were in contact 49 times. That morning, McClellan received two calls from a contact named Johnny. McClellan then made a short call to Diggs at 7 am. Around the same time, CSLI showed Diggs’s phone connected to a tower in Matteson, Illinois. (CSLI is generated whenever a cell phone connects to a cell tower; by identifying which towers a phone connects to, law enforcement can approximate a phone’s location with great precision. See United States v. Lewis, 38 F.4th 527, 536 (7th Cir. 2022).) Other evidence —including CSLI, phone records, and a marriage license —suggested that Diggs lived in Matteson. Ten minutes later, McClellan texted Johnny: “Bet. He on his way.” Johnny called McClellan at 7:54 am, and McClellan called Diggs at 7:55 am. Less than 10 minutes later, McClellan texted Johnny: “We on our way.” Several calls between Johnny and McClellan followed.

Shortly before the robbery, CSLI showed that Diggs and McClellan’s phones connected to towers in Hinsdale. Diggs’s phone pinged a tower a mile and a half from Razny Jewelers. A third phone, which connected to the same tower as Diggs’s, 6 No. 22-1502
