Jeffrey Dahmer's bruised and battered corpse was forever immortalised in pictures taken after he was bludgeoned to death.
The Milwaukee Cannibal was murdered by a fellow prison inmate, Christopher Scarver, at around 8am on November 28 1994. The then-34 year old's skull was crushed with a 20" metal weights bar taken from the gym at the Columbia Correctional Institute. Scarver also repeatedly smashed his head against a wall.
In 2015, Scarver told The New York Post he confronted Dahmer with a newspaper clipping about his crimes.
He recalled: “I asked him if he did those things ’cause I was fiercely disgusted. He was shocked. Yes, he was. He started looking for the door pretty quick. I blocked him. He ended up dead. I put his head down."
Details about his grisly death, which came just three years after he was jailed for 16 first degree murders, were also provided in a coroner's report.
After he was attacked and the alarm was raised, he was transported by ambulance to a nearby hospital where he was pronounced dead an hour later. Dr. Robert Huntington III, a forensic pathologist at the University of Wisconsin who later performed the autopsy on Dahmer's body, noted that the cannibalistic necrophile was wearing shackles.
He noted: "Such was the fear of this man that chains were on the feet, even post-mortem."
It is more likely that he was shackled as some prisoners had been known to fake injury or even their own death in order to escape prison. It shows that Dahmer was seen as a high risk prisoner - one who may have killed again had he escaped custody.
In photos taken after his death, Dahmer's face is discoloured with heavy bruising, with large dark and yellow patches spreading across his face. His eyes are also black from the fatal beating.
