Dahmer raped, murdered and chopped-up seventeen men and boys. And was ultimately sentenced to fifteen life sentences in 1994.
In prison Dahmer had a personal prison guard protecting him. But one day he was left alone with killer, Christopher Scarver. Scarver says he was 'disgusted' by Dahmers crimes and when the opportunity popped-up he crushed Dahmer's skull with a metal bar he got from the gym.
Scarver blames the prison food for his homicidal rage. Apparently there's some kind of twisted pecking order among serial killers.
