What causes people to become killers? KILLER PSYCHE is a true crime podcast from Wondery that covers high-profile cases that shocked the world. Host Candice Delong uses her experience as a clinical psychiatric nurse and FBI Criminal Profiler to dissect the motivations and behaviors of the most terrifying criminals in history. In a recent episode, Candice explores the case of Pedro Rodrigues Filho, also known as The Brazilian Dexter. Rodrigues went on to murder, by his count, more than 100 people -- most of them while he was behind bars. To many, he was a hero -- a vigilante seeking justice for victims. But to others, he was just a cold-blooded murderer. This is just a preview of Killer Psyche, but you can listen to the full episode at http://wondery.fm/KP_MomsAndMurder
