Jeffrey Lionel Dahmer was born on May 21, 1960, in Milwaukee, Wisconsin. He was the son of Lionel and Joyce Dahmer. As a child, Dahmer was described as being shy and withdrawn. He displayed troubling behavior from a young age, such as an obsession with dead animals.
Dahmer's parents' divorce when he was 18 years old had a profound impact on him. He became increasingly isolated and began to delve deeper into his disturbing fantasies.
Between 1978 and 1991, Dahmer committed a series of gruesome murders, predominantly involving young men and boys. He lured his victims to his apartment, where he would drug them before strangling or stabbing them.
Notorious for his necrophilic tendencies, Dahmer would engage in acts of sexual assault and dismemberment with his victims' bodies. He also attempted to create zombies by injecting acid into their brains in a futile attempt to keep them alive.
Dahmer's killing spree came to an end in 1991 when one of his intended victims managed to escape and alert the police. Upon searching Dahmer's apartment, authorities discovered evidence of his heinous crimes, including human remains.
During his trial, Dahmer pleaded guilty but insane to 15 counts of murder. However, he was found to be legally sane and was sentenced to 15 consecutive life terms in prison.
