During most federal trials, there is a point where things feel like they will go in a certain direction. The lawyers are done with their closing arguments. The jury leaves the room. Everyone has to wait. Last month’s events at the E. Barrett Prettyman federal courthouse in Washington, D.C., were not that moment.

Shamell Naquan Joyner had been sent to jail for a month. On the surface, the charges seemed pretty solid: prosecutors said he robbed seven 7-Elevens, several gas stations, and took cars with guns over the course of several weeks in the spring of 2023. Ten days of witness testimony, nine defense lawyers, three prosecutors, and a 28-count indictment were all part of the case. By all accounts, it was a very serious case with a lot of resources.
The jury then went to talk about the case, and one of them reached into his jacket pocket.
A juror found a folded piece of paper with a white powdery substance inside the breast pocket of a jacket that had been found in a stolen Toyota. Prosecutors said the thief wore this jacket during two of the May 2 thefts. The judge and prosecutors thot it looked like drugs. Someone else on the jury found a crumpled Chinese yuan bill in a sweatshirt that was also part of the physical evidence. The FBI, the prosecutors, and Joyner’s defense team all didn’t know those things were there. In a transcript that CNN later got, the jury foreperson talked about the event to the court the next morning. It was a tone that was almost confused and dull. “She pulled out — it looked like a receipt, but there was a white powder or white substance inside,” the supervisor said.
Judge Rudolph Contreras, who has been a federal judge for ten years and has seen a lot, didn’t hold back when he spoke out. In a later opinion, he said, “I shared Mr. Joyner’s shock that police had not found the Chinese Yuan, note, and powdery substance in the physical evidence.”” On the bench, he said in jest that Joyner’s lawyer in New York was probably shocked that any money got past the police. There’s a chance that the judge was trying to make things less serious. A number of lawyers in Washington, D.C., told CNN that they hadn’t heard of anything so embarrassing in a long time. However, some former prosecutors did say that juries do sometimes find things that investigators missed.
The discovery made things very difficult for the law. Both pieces of clothing were very important to the prosecution’s case because they linked Joyner to two of the thefts. The jury might have made a bad decision either way if they had looked at the yuan and what looked like drugs while they were deliberating. Contreras worked slowly, calling each juror in one at a time to explain that the items were not part of the evidence that was admitted and to let them know they could throw them out. Twelve of them said they could. The discussions began again.
When it came out, the verdict was not fair. On the fifth day of deliberations, the jurors told the judge that they could not agree on 15 of the remaining charges, including 5 armed robberies and 1 carjacking. They said they had different ideas about who the suspects were and what reasonable doubt meant. A partial verdict was okay with Contreras. Joyner was found guilty on 13 counts that included a theft in downtown Washington, D.C., in April 2023 and a group of crimes that happened on May 2, 2023. The US Attorney’s Office said that people who are found guilty of those crimes must serve at least 31 years in prison.
It’s important to think about what this case really showed. The FBI agents who worked with this evidence, the prosecutors who spent a month on trial, and the defense lawyers who looked over discovery all missed what a jury member found in just two minutes by checking a pocket. The FBI wouldn’t say anything about how that happened. The US Attorney’s Office also didn’t give a straight answer. People will likely talk about that silence more than anything else in this case
