Collis McCaster, now 48, was found unresponsive in his private cell at 8:20 a.m. Sunday at the William Donaldson Correctional Facility in Bessemer, Alabama. He was pronounced deceased at 8:45 a.m. “At this time there is no evidence of trauma or foul play and an autopsy will be performed to determine the cause and manner of the death,” Jefferson County Chief Deputy Coroner Bill Yates stated in a report obtained by NorthEscambia.com.
