A federal jury in Memphis, Tennessee, convicted a man on Friday for a series of brazen bank robberies, one of which ended with the defendant shooting two people with an assault rifle. At trial, the defendant was convicted of robbing three banks and joining a conspiracy that robbed a total of five bank branches. This is the last of eight defendants indicted in this case, which charged robberies and related firearm charges. All defendants have now been convicted either by guilty plea or at trial.

"This defendant was part of a violent robbery crew whose actions put lives in grave danger and seriously injured innocent people," said Assistant Attorney General A. Tysen Duva of the Justice Department's Criminal Division. "The series of bank robberies committed by these eight defendants terrorized bank employees and customers and threatened the lives of hardworking Americans. The Criminal Division will aggressively prosecute those who commit violence, just as it has here."

"Bank robbery committed with a firearm is an inherently violent offense and threatens the very fabric of our financial institutions that provide commercial services to citizens and the community," said U.S. Attorney D. Michael Dunavant for the Western District of Tennessee. "These brazen and disturbing armed robberies of multiple Memphis banks by Patterson and his co-conspirators terrorized the community and inflicted fear and harm on multiple victims. Now they will have plenty of time in federal prison to suffer the consequences of their violent criminal conduct, and the citizens of Memphis will be safer for it."

"Friday's conviction should send a strong message that violent crime will not be tolerated, and law enforcement will not rest until violent offenders are caught, prosecuted, and held accountable for their actions," said Special Agent in Charge Joseph E. Carrico of the FBI Nashville Field Office. "The FBI will continue to work alongside our local, state, and federal law enforcement partners to fight violent crime in communities across Tennessee."

Evidence at trial proved that over about eight months between April 2023 and December 2023, the defendant, Mario Patterson, 45, joined a conspiracy with his co-defendants to rob banks throughout Memphis. The robbers even attempted to rob the same bank branch twice.

Patterson carried a gun in each robbery, and during one attempted robbery he shot two people with an assault rifle. In another robbery, Patterson wore a bulletproof vest and pointed a rifle at bank employees while a co-defendant stole thousands of dollars from the bank. By the end of 2023, Patterson and his group stole over $160,000 from Memphis-area banks.

Patterson's sentencing is scheduled for April 24. Three of Patterson's co-defendants ─ Robert Haley, Devin Hinds, and Joshua Cribbs ─ were sentenced in late 2025 for their role in the offenses, with Haley receiving 17 years in prison, Hinds receiving 16 years and 1 month in prison, and Cribbs receiving 12 years in prison. The four additional co-defendants, Travis Drain, Monterrio Trenell, Marquarius Trenell, and Courtney Trenell, face sentencing later this year.

The FBI and the Memphis Police Department's Safe Streets Task Force investigated the case. This case is part of the Safe Streets Task Force's efforts to prosecute violent crimes in Memphis, Tennessee and surrounding areas.

Trial Attorney Ashleigh Atasoy of the Criminal Division's Violent Crime and Racketeering Section, with assistance from Trial Attorney Aaron Hendricks, and Assistant U.S. Attorneys Gregory A. Wagner and Tony Arvin of the U.S. Attorney's Office for the Western District of Tennessee are prosecuting the case.
