John Wayne Gacy started making paintings in prison after being arrested for the murder and abuse of at least 33 young boys in the United States Of America in the 70's.
He is one of America's most famous serial killers and several movies were made with these gruesome crimes in mind.
Like IT, where a clown is terrorising a small community.
In this video you will see 6 of those paintings, a glimpse into his mind & serious fuel for nightmares.
