In this episode, Ally covers the murders of the Gustafson family in Townsend, Massachusetts, a case that is often remembered for its most chilling details, but at the center of it all were Priscilla Gustafson and her two young children, Abigail and William. We get into the family at the heart of this story, the terrifying events that had already unfolded in another nearby home, and the trail of warning signs that came before everything escalated into one of the most haunting cases in Massachusetts true crime.

We’re giving you a little taste of who we are, the true crime cases that first pulled us in, and the stories we still can’t stop thinking about. Before the deep dives, courtroom chaos, and cases that completely consume us, this is the perfect place to start if you want to get to know us a little better. It’s personal, a little chaotic, and very much us.

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.
