DETROIT (AP) -- An inmate has been charged in the slaying of a Wayne County sheriff's deputy at a jail in downtown Detroit.
Deandre Williams, 28, of Detroit, was arraigned Wednesday on charges of first-degree premeditated murder, murder of a police officer, felony murder, unarmed robbery and escaping jail through violence, according to the county prosecutor's office.
The sheriff's office has said Cpl. Bryant Searcy, 50, was checking cell doors on Sept. 2 when he was attacked as he walked past one he thought was locked.
Searcy, who joined the sheriff's office in 2002, was found unresponsive by other deputies and died later at a hospital.
Prosecutors said Williams was being held at the jail on a carjacking charge.
He faces a Sept. 23 probable cause conference and a Sept. 30 preliminary examination in Searcy's slaying.
Authorities have said the attack was being reviewed to determine if sheriff's office procedures were followed.
