An actor portrays serial killer John Wayne Gacy at Killers: A Nightmare Haunted House, at Clemente Soto Vélez Cultural Center on October 5, 2012. Visitors can see a  exhibit of drawings and other artifacts once belonging to real-life monsters such as John Wayne Gacy and Charles Manson, donated by an anonymous collector. Each room of the house depicts a scene based on a notorious serial killer, with performers acting as murderers, victims, or both. Killers will run September 28 through November 3, 2012  on Manhattan’s Lower East Side.  AFP PHOTO / TIMOTHY A. CLARY        (Photo credit should read TIMOTHY A. CLARY/AFP/GettyImages)
