When 17-year-old Valerie Tyndall vanished without a trace, investigators believed they were chasing a missing persons case. By Part Two, they were racing to prove something far more sinister.

Rush County detectives and the U.S. Marshals uncover a series of contradictions that place Valerie's last known moments at Patrick Scott's home. A search of his property reveals hidden evidence, suspicious electronics, and a carefully concealed collection of personal mementos that raises even more questions.

As investigators analyze mountains of digital evidence, GPS records, surveillance footage, and phone data, a chilling timeline begins to emerge. An unusual trip to a distant Home Depot, unexplained purchases, and a carefully orchestrated pattern of movement point detectives toward a terrifying possibility.

Then comes the breakthrough no one expected.

Four highly trained human remains detection dogs independently converge on the same location near Patrick Scott's property. But when divers search the pond where every dog indicated, they find... nothing.

What seemed like a dead end instead becomes one of the most important moments in the investigation.

In this episode, detectives Randy Meek and Sean Smallwood of the Rush County Sheriff's Office, Senior Inspector Tom Abreu of the U.S. Marshals Service, and Indianapolis Metropolitan Police Department K9 handler Tony Weaver explain how modern technology, forensic mapping, and the extraordinary abilities of cadaver dogs transformed an impossible investigation into a case that was finally beginning to break open.

Sometimes the biggest breakthrough isn't what investigators find.

It's what they almost miss.
