Warning: This video contains graphic descriptions of violence. Twenty-four years ago, Jeffrey Dahmer was beaten to death in prison while serving 16 life sentences. In 1993, the man known as “the Milwaukee Cannibal” granted Inside Edition a jailhouse interview and was forthright about his crimes.

During his reign of terror between 1978 and 1991, Dahmer killed 17 men and boys and kept some of their body parts in freezers inside his home. He was eventually arrested in 1991 when a victim escaped.
