Hey everyone. The story that's at the heart of the preview I'm about to play for you is,

without a doubt, one of the craziest things I've ever heard. As I listened to the preview and

then did some reading on my own, I just kept saying, this is some of the wildest stuff ever.

If you're a fan of the TV

show Dexter, you're probably going to be intrigued by this story. The podcast is called

Killer Psychie, and it's a true crime podcast from Wondry that explores the most basic

yet difficult question with killers and other criminals. Why? Why do they do what they do? What makes

their minds tick? Host Candice DeLong uses her five decades of experience as a clinical

psychiatric nurse and FBI criminal profiler to dissect the motivations and behaviors of the

most terrifying felons in history.

The most recent episode of Killer Psyche is the one I was just talking about.

Candice explores the case of Pedro Rodriguez Filio, also known as Killer Petey, or the Brazilian Dexter.

At age 14, Rodriguez murdered the deputy mayor in his town because the mayor

had fired his father. Rodriguez went on to murder, by his count, more than 100 people,

most of them while he was in prison. To many, he was a hero of vigilante seeking justice for

victims, but to others, he was just a cold-blooded

murderer. Enjoy this preview and listen to Killer Psyche on Apple Podcasts or Amazon Music.

From Wondery and Tree Fort, I'm Candice Dillong, and this is Killer Psyche.

The Wendary! I've spent five decades studying people's minds through my work as an FBI profiler and psychiatric nurse.

I've interviewed dozens of murderers,

including serial killers, and the question of why they did it is what I get asked time and time again. I want to give you a satisfying answer, so I'm diving deep into the mindsets of these criminals
