Nine deputies in Chatham County, Georgia have been fired following an investigation into a mentally ill suspect’s death in an isolation cell this January, NBC News reports.

On New Year’s Day, 22-year-old Mathew Ajibade was arrested after allegedly attacking his girlfriend during a bipolar episode. According to his family, Ajibade was then handcuffed to a restraint chair, tasered, and left to die. From The NY Daily News:

During booking, Ajibade allegedly began fighting with deputies and injured three of them, the sheriff’s office said. One reportedly had a concussion and broken nose.

Ajibade was placed in a restraining chair in an isolation cell, where he was later found unresponsive, officials said. The results of his autopsy have not been released because a prosecutor is weighing whether to file criminal charges, officials said.

On Friday, the Chatham County Sheriff’s Office announced it had terminated nine deputies for their role in the incident following parallel investigations by internal affairs and the Georgia Bureau of Investigation. Two other deputies involved in Ajibade’s arrest were fired earlier this year for unrelated policy violations and another retired.

Additionally, the sheriff’s office said it has instituted a number of policy changes, including procedures “to ensure immediate notification to onsite medical personnel when a person with medication arrives for the booking process” and a clear policy “of when Tasers may not be used.”

According to Chatham County District Attorney Meg Heap, the findings of the investigation are unlikely to be made public until evidence is put before a grand jury, which will likely happen next month.

“I want this case to be tried in a court room,” Heap told the Savannah Morning News, “not a court of public opinion.”
