Jeff Dahmer was sentenced to almost 1,000 years in prison but he only served a fraction of that after he was murdered by a fellow inmate.
Here's everything to know about how Jeff Dahmer died, and who killed him.
Who killed Jeff Dahmer?
Christopher Scarver bludgeoned the serial killer to death with a 20" long metal weight pole taken from the prison gym.
In 2015 he told The New York Post that Dahmer had been winding up inmates by shaping his prison meals in to limb shapes, squirting ketchup over them to look like blood. Scarver, who was 25 at the time, had kept a newspaper cutting about Dahmer's crimes, confronted him about if it was true or not while he was on a toilet cleaning duty with the control freak necrophile and another lag, Jesse Anderson, who was also killed in the same manner.
He recalls being poked in the back, adding: “I turned around, and [Dahmer] and Jesse were kind of laughing under their breath. I looked right into their eyes, and I couldn’t tell which had done it.”
How did Jeffrey Dahmer die?
Scarver followed Dahmer toward a staff locker room, grabbed a metal bar from the weight room and confronted Dahmer with the news story he had been carrying in his pocket.
“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."
At his trial for the double killings he pleaded no contest in exchange for a move to a federal penitentiary. Scarver was sentenced to two life terms on top of the life sentence he was already serving.
When did Jeffrey Dahmer die?
Jeffrey died on November 28 1994 when he was aged 34. He died at the Columbia Correctional Institution in Wisconsin. He died from severe head trauma after being beaten to death.
For his first year in prison he was kept in solitary confinement for his own safety - at his request.
Later he found God, and after leaving solitary, began attending church services held in the prison. As a Born Again Christian, it is claimed he told his pastor that he believed him still being alive after his heinous crimes was an offence to God.
In his book A Father’s Story, his dad Lionel reveals his son read a lot of scripture and creationist texts while serving his sentence.
Ironically it was his new found faith that would lead to his death - he was on his way to the prison chapel when he was killed.
