People Are Haunted By How John Wayne Gacy Refers To His Victims

True crime fans were left horrified when they tuned in to Netflix's Conversations With A Killer: The John Wayne Gacy Tapes and learned how the notorious murderer referred to his victims.

The three-part documentary dives into Gacy's psyche in search of explanations for the vile crimes he committed through footage recorded between Gacy and his defence team, and interviews and testimonies from those involved.

Check out the trailer here:

Between the years 1972 and 1978, John Wayne Gacy raped and murdered at least 33 men - though investigators believe this number could be even higher.

Working as a local contractor, Gacy used his position to hire young men, who would later be reported missing soon by concerned loved ones.

It wasn't until he was arrested for two sexual assaults that police began to look into Gacy as a possible suspect for the unexplained disappearances, and eventually found a number of bodies buried under his Chicago home.

During the documentary series, viewers hear Gacy speak to his legal team about how he would to lure men to his home, expressing no remorse for his actions.

As he boasts about his killings, Gacy is heard describing the men he killed as "the harmless virile ones", before later revealing that he considered his victims to be "not human beings".

Understandably, the chilling confession left viewers feeling uneasy.

One horrified Netflix user tweeted: "This John Wayne Gacy Netflix doc gonna give me nightmares. The way he says 'they’re not human beings, they’re like something you get at the store. once you’re tired of it you just break it' really got under my skin."

Victims of John Wayne Gacy's killings are still being identified, with one body being named as recent as last year.

After he was convicted of murdering at least 33 people, Gacy was sentenced to death in 1980. He executed by lethal injection in 1994.
