A grand jury has indicted three people in the death of a 21-year-old college student whose body was found in restraints at a county jail in Savannah.

Two of those indicted are ex-jail employees and one was a contract health worker.

Indictments returned Wednesday charge all three with involuntary manslaughter.

Mathew Ajibade died Jan. 1 after he was booked at the Chatham County jail on a domestic violence charge. He was found strapped into a restraining chair in an isolation cell. Ajibade's death certificate says the coroner ruled his death a homicide caused by blunt-force trauma.

Sheriff Al St. Lawrence last month fired nine deputies in connection with Ajibade's death. The Georgia Bureau of Investigation was called in to investigate.

Ajibade's family isn't satisfied with the outcome. “They are disappointed that nine out of 12 people involved in their son or cousin or brother’s death have gotten away without any criminal liability,” attorney Mark O'Mara tells the Savannah Morning News. The Ajibade family filed suit earlier this month to have Chatham County District Attorney Meg Heap removed from the case, saying she had a conflict of interest with the Sheriff's office.

In a statement, the Sheriff's office said: "We are saddened by the loss of life in the Matthew Ajibade case and continue to work diligently with the District Attorney to ensure justice is served. As is our procedure in all in-custody deaths, CCSO requested GBI assistance in this investigation and cooperated fully in all aspects. We appreciate all of the work the Grand Jury and District Attorney on this case and are confidant in the legal process."
