Clark's family, which hailed from Troy, New York, was affluent but dysfunctional; his parents were both alcoholics who physically and emotionally abused their four children, and his two brothers were both arrested as adults for murder and domestic violence. Clark's mother would dress him in girl's clothes when she was drunk, and as a result he grew to identify himself as a woman and would often wear women's clothes. He exhibited sadistic tendencies from a young age, delighting in torturing animals and bullying other children. As an adult, he trained as a chef at the Culinary Institute of America and worked in upmarket hotels, restaurants and cruise liners. However, his mental illness often led to the termination of his employment and he would often get back at his former employers by committing acts of theft and sabotage. He later drifted through a series of menial jobs and a stint in the Navy, which ended when he was discharged after being diagnosed as a paranoid schizophrenic. He eventually settled in Maryland, where he was often homeless.
While Clark later claimed to have begun killing as a teenager, his first documented victim was his six-year-old neighbor, Michelle Dorr, whom he killed in May 1986. After stabbing her to death with a knife, he tried to have sex with her corpse. He also cannibalized her before dumping the body. Clark was not considered a suspect at the time, however, as police initially suspected the girl's father. In 1992, he murdered Laura Houghteling, a young woman whose mother had given him a part-time gardening job. The local police, who had begun to suspect him for Michelle Dorr's murder, investigated him and arrested him within days.
He pleaded guilty to second-degree murder the following year and was sentenced to 30 years in prison. In 1999, he was convicted of murdering Michelle Dorr after other prisoners testified that he had bragged about committing the crime. Another 30 years were added onto his sentence, plus 10 more for a past robbery charge, meaning that Clark is effectively serving life in prison.
