#8 – John Wayne Gacy
This psychopath raped and murdered 33 young men between 1972 and 1978 on Chicago’s ground. Gacy lured his victims into his home with the promise of money for easy jobs. He would then murder his victims by strangling them with a tourniquet.
He buried 26 of his teenage boy victims in his home’s crawlspace. Gacy was convicted of more than 30 murders and got sentenced to death. He was injected with a lethal injection in 1994.
