Born in May 1960 in Milwaukee, Jeffrey Lionel Dahmer began as a bright, imaginative child. After a minor surgery at age four, he became withdrawn and detached. With a distant father and ill mother, his isolation deepened through school despite his intelligence. After his parents’ separation in 1978, Dahmer lived alone, growing increasingly unstable and lonely. In 1991, his crimes were exposed after a victim escaped, revealing years of hidden violence. Dahmer’s tragic descent highlights the devastating impact of neglect, trauma, and untreated mental illness.
