MARIANNA, Fla. - Police say an 82-year-old Ontario man has been killed in a Florida jail, allegedly by his cellmate.

Arthur Williams of Tillsonburg, Ont., was in custody after being charged for allegedly trying to lure a nine-year-old boy.

Marianna, Fla., police chief Hayes Baggett says officers were called to the Jackson County Correctional Facility early Monday morning to investigate a reported homicide.

Investigators say staff found Williams dead during a security check.

Frederick Patterson, 21, of Brunswick, Ga., is facing a murder charge and is alleged to have killed Williams in what police called an "ambush style attack."

Williams was charged in October 2017 with loitering and prowling, trespassing, aggravated stalking, making a threatening phone call and attempting to lure a child under the age of 12.
