Rimson was sentenced to life plus 20 years for the Suwanee gun-sale robbery killing.

A life-plus-20 sentence after a jury conviction is the court's judgment. It is not a new charging decision, and it is not an open accusation. Reporting dated Friday, Sept. 25, 2026, from the Gwinnett County District Attorney's Office and Atlanta outlets says Jermaine Dondi Rimson, who was 17 at the time of the crime and is now 21, was convicted of felony murder, armed robbery, aggravated assault, and criminal attempt to commit a robbery in the July 19, 2022 death of Abel Castellanos, 21, in Suwanee, and sentenced to life in prison plus 20 years. That term is the judgment.

Prosecutors said Castellanos posted on social media that he wanted to sell a .380 handgun. Miguel Gabriel Flores arranged a meeting at Castellanos's Suwanee apartment as if to buy it, but planned a robbery, the Gwinnett County District Attorney's Office said as reported by Atlanta News First and WSB-TV.

Flores recruited Rimson and Joshua Poteat, both 17 at the time, according to prosecutors. When Castellanos showed the gun, Rimson got out and shot him in the chest, then took a second handgun before the group fled. Those are the facts prosecutors presented and the verdict the jury returned against Rimson. Poteat is described as the alleged getaway driver and still awaits trial.

Flores was previously convicted in September 2025 of felony murder and related counts and sentenced to life with the possibility of parole. Rimson's life-plus-20 sentence is a separate judgment for Rimson. It is not Flores's sentence, and it is not a disposition of Poteat's pending case.
