For the officers of Denver Police Department, every case demands professionalism, every victim deserves justice, and every investigation must remain objective. But what happens when suddenly, the name at the top of the missing persons file isn't a stranger? What happens when the woman you're desperately searching for is your own daughter?

A devoted mum of two, Heather DeWild, vanished without a trace.. and for one retired police officer, the stakes had never been higher..

The morning began like any other summer day. It was set to be another gorgeous day at a quiet Massachusetts pond.

Molly Bish arrived for her lifeguard shift, but within minutes, she was gone. Her radio, towel, and shoes all left behind.. like they were frozen in time.

In broad daylight, at a place where families gathered to enjoy nature, someone made Molly disappear.

And the mystery of what happened to her would haunt an entire community..

It was supposed to be an exciting weekend - Wrestling Star Chris Benoit was due to appear at WWE's Vengeance: Night of Champions in Houston.

But he never made it. In fact, he quietly sent texts from his family home explaining his wife and son were sick. But something about his demeanour felt .. odd.

Inside that house, horrors too horrific to comprehend were taking place..

Nancy was a mother, described by loved ones as fiercely protective of her son and determined to build a stable life away from the chaos of the wrestling world.

Her son, Daniel, was just seven years old— his life should’ve been school days, playing out with friends, and the safety of being completely loved and looked after.

Instead, their absence would become part of one of the most discussed tragedies in modern wrestling history.
