John Wayne Gacy is the infamous American serial killer also known as the Killer Clown. Despite his civic involvement in Chicago, Gacy assaulted and murdered over 33 young men over the space of a decade. He buried the bodies of his victims the crawlspace under his house.
There were so many bodies that police had to bulldoze the house in order to complete the excavation efforts.
In the 80s, the house was rebuilt and given a new address.
