John Wayne Gacy was executed in prison 31 years ago on May 10, 1994

John Wayne Gacy.,a.k.a. the Killer Clown, died 31 years ago today.

On May 10, 1994, the serial killer — who was convicted of murdering at least 33 teen boys and young men throughout the 1970s — died while at a correctional facility in Illinois. Though his crimes were among the most heinous in American history, Gacy maintained a disturbing double life as both an upstanding citizen and a sexual predator.

On the outside, he was seen as a friendly community man who often entertained children in local hospitals and birthday parties — a persona that later earned him the nickname the “Killer Clown.”

In 1980, he was convicted and sentenced to death. When asked in a recording featured in Netflix’s Conversations with a Killer: The John Wayne Gacy Tapes about how he felt about the trial being over, the serial killer said, “How can you feel relief about something you still don’t understand?”

“Because they say I’m guilty, I’m supposed to feel guilty now? I don’t,” he said. “I have no remorse.”

Here’s what to know about John Wayne Gacy’s death in prison 31 years ago.

On March 13, 1980, Gacy was convicted of murdering 33 people and sentenced to die for 12 of those killings. According to History.com, Gacy made paintings of clowns and other figures that sold for thousands of dollars during his years on death row, until he was eventually executed by lethal injection.

According to ABC News, he was given three different chemicals: one to knock him unconscious, one to stop his breathing and one to stop his heart. However, there was an error during the process, as there was a clog in the line that stopped the second chemical from completely going in at first.

Per the outlet, it took 18 minutes for him to die, which is about four times longer than expected.
