It’s one thing to tell the story of bank robbers Bonnie and Clyde.

Who wants to see that scary clown face?

Gacy was executed in 1994.

Later this month, the museum will include one of his clown suits, his leather jacket and his wallet in the show. Sam Amirante, Gacy’s public defender, and Danny Broderick, the authors of “John Wayne Gacy: Defending a Monster” will add some context to this choice. Why is the public fascinated with serial killers.

The museum has shown items from serial killers before, including Ted Bundy’s Volkswagen.
