An inmate at Patton State Hospital found with "severe upper body trauma" was beaten so badly that he died from his injuries at Loma Linda University Medical Center, coroner's officials and news reports indicated Tuesday.
The unidentified 65-year-old man was found around 11:40 a.m. Saturday at the mental health facility located just north of Highland, according to the San Bernardino County coroner's office. He was taken to Loma Linda University Medical Center, where he died about six hours later.
A 40-year-old was arrested after the attack on suspicion of murder, according to the news agency, who added that the two men had been alone in a room that normally sleeps four people when the attack happened.
The man's yells for help sent staff running to his aid, a police sergeant told The Times.
