Officials say an inmate was found dead in his cell at a state prison in Lancaster and his cellmate is suspected in his death.
California State Prison-Los Angeles County spokesman Lt. George Allen says the body of Robert Mobley, 68, was found Tuesday night. A sheriff's spokesman says Mobley had been beaten.
Allen says Mobley had been serving a 453-year sentence following his conviction in San Diego County for sodomy on a victim incapable of giving legal consent because of a mental disorder or developmental or physical disability.
Allen says the suspect is Brad Hinson, 27. He was serving a two-year sentence for vehicle theft.
An autopsy is scheduled to be conducted later in the week.
