Welcome to Probation Behavior, a true crime podcast hosted by two friends who can’t stop asking “how did we get here?”

In this trailer, we’re giving you a quick peek into what you can expect each week. We cover lesser-known cases, wild twists, and the psychological layers behind the crimes that stick with you long after the episode ends.

We’re not here to just tell you what happened. We’re here to unpack why it happened, how it escalated, and what it says about people, relationships, and the systems around them.

If you love cases that unravel slowly, unexpected turns, and conversations that feel like you’re right there with us, you’re in the right place.
