John Wayne Gacy became notorious as the "Killer Clown" because of the many block parties he threw for his friends and neighbors, entertaining children in a clown suit and makeup, under the name of "Pogo the Clown".
Keep your eyes open this week, as filmmaker Kellie Madison will be shooting some scenes for her new project: “Dear Mr. Gacy.”
The upcoming documentary will be based on the book Moss wrote while a student at University of Nevada, Las Vegas, when he got to meet and talk with Gacy on several occasions while the serial killer was in prison.
"It's been interesting to talk to people because they all have the same message. It's so clear — that there are predators all around, especially now on the Internet," Madison told Crain’s Chicago.
"If you're a kid, you have to be careful. The guy next door may seem friendly and jovial and charming, but you just don't know."
Places you’ll most likely find her are Lincoln Park and the Lakeview neighborhood, where the filmmaker will be interviewing police officers and attorneys involved in the Gacy murder investigations.
