Some cases are never closed. Some killers are never caught. Some victims never get justice.

This is a 20 week deep dive into the most chilling, mind-bending, and unforgettable cold cases in history taught by a Special Agent in Charge who has spent a career chasing the truth. Every week, one case. Every case, a story that changed the world of investigation forever.

We're not talking textbooks. We're talking real files, real evidence, real failures and the relentless pursuit of answers that justice demands.

Don't worry about when you start. The moment Week 20 ends, we go right back to Week 1. Every student who stays in will cover every single case.

A note for students and parents: These are real cases involving real victims. Some cases include graphic details about violence, missing persons, and crime scenes. All material is presented in an age appropriate way but students should be emotionally prepared for serious, sometimes difficult subject matter. If you're 12 or older and ready to think like an investigator, you belong here!
