WATCH: Jeffrey Dahmer speaks about his arrestIt’s widely understood that the American murderer was beaten to death by a fellow inmate at Wisconsin's Columbia Correctional Institution, a man named Christopher Scarver.Scarver was in jail for shooting a man and was cleaning the prison gym when he was left unsupervised with Dahmer and one other inmate.He killed Dahmer and the other man, Jess Anderson, with a 50-centimetre-long metal bar that weighed just over 2 kilos according to the New York Post."[Dahmer] crossed the line with some people—prisoners, prison staff. Some people who are in prison are repentant—but he was not one of them," Scarver later told the outlet."I turned around, and [Dahmer] and Jesse were kind of laughing under their breath.
