10 Serial Killers Who Turned Themselves In

7. Elmer Wayne Henley

Elmer Wayne Henley was a participant in the infamous Houston Mass Murders, where at least 28 young men were kidnapped, tortured, raped and killed by Dean Corll between 1970 and 1973, with Henley often acting as an accomplice.

Henley met Corll in 1971 at the mere age of 15, and soon thereafter began helping lure young boys back to Corll's home, initially believing them to be sold into a sex trafficking ring.

Despite Corll admitting to him that his prior lures had been killed, Henley continued to assist in acquiring victims, and by the end of 1972, had participated in selecting and killing at least nine teenage boys with Corll. During the summer of 1973, Henley then helped Corll murder at least another seven young men.

The murders came to an abrupt end on August 8, 1973, however, when Corll became outraged at Henley for bringing a young girl back to his home and subsequently threatened to shoot him.

To "apologise," Henley agreed to help Corll rape and murder the two teens bound at their home, only to be convinced by one of the victims to pull a gun on Corll, eventually firing six shots at Corll and killing him.

Henley then untied the two teenagers, phoned the police and confessed to his role in the Houston Mass Murders. Despite his complicity in many of the Corll-instigated killings, he was only convicted of six murders, while his killing of Corll was deemed self-defense.

Today, Henley is incarcerated in the Mark W. Michael Unit at Anderson County, Texas, with his next eligible parole date set for October 2025, when he will be 69 years of age.
