Francisco de Assis Pereira, a.k.a. "The Park Maniac", is a (possibly prolific) Brazilian ephebophilic serial killer, sexual abuser, and attempted cannibal. Pereira would approach young local women between the ages of 18 and 24 and claim that he was a fashion photographer searching for potential future models. He would give them an opportunity to work as a model and instructed them to follow him to the state park, where a session of photos would be taken. At the park, the victims would be brutally abused and strangled to death with some sort of ligature, such as a rope, shoelace, or scarf. After killing his two last known victims, he bit their corpses multiple times and tried to cannibalize them, but gave up.
