SAVANNAH — A judge on Thursday set an October trial date for two former sheriff's deputies and a nurse charged with involuntary manslaughter in the case of a 21-year-old detainee who died in restraints at a county jail. Mathew Ajibade of Savannah was found dead inside a cell and strapped to a restraining chair after he fought with deputies booking him into the Chatham County jail on domestic violence charges Jan. 1. A grand jury indictment on June 24 said former Cpl. Jason Kenny shocked Ajibade with a Taser while he was being held in restraints.
