Reference: Jeffrey Dahmer a Serial Killer

Jeffrey (Jeff) Lionel Dahmer (May 21st, 1960 – November 28th, 1994) was an American serial killer who killed 17 men between 1978 and 1991 (with the majority of the murders occurring in 1991).

Dahmer was born to a fundamentalist father in Milwaukee, Wisconsin. At age eight, his family moved to Bath, Ohio, near Akron.
From his earliest youth he was extremely shy and, according to his father, was molested as a child by a neighbor.
He collected dead animals and showed signs of necrophilia, but this was revealed only at his trial.
He was also a closeted alcoholic and homosexual and suffered from extremely low self esteem. His parents divorced when he was in his teens.

He committed his first murder at the age of 18, killing a young man he had invited to his house because Dahmer "didn't want him to leave." Later on he went to college but performed poorly. His father convinced him to join the military, and he appeared to recover some vitality as he became an army medic.
Shortly after his military career, he began the string of murders that led to his arrest many years later.

Most of his victims were African American men whom Dahmer subjected to sexual assaults. His main goal was for a completely compliant sexual partner, essentially making necrophilia his motivation for killing.
He achieved notoriety after his arrest, following the discovery of several decaying bodies in acid vats in his apartment. Severed heads were found in his refrigerator and an altar of candles and human skulls were found in his closet.
Accusations soon surfaced that Dahmer had practiced necrophilia and cannibalism.
Dahmer admitted to eating the biceps of his victims, noting that human flesh "tasted like beef" to him.
