A mystery in Oklahoma, as a family wonders and waits to see if police can solve the mystery of what really happened to a single mom.

A beautiful nurse goes missing. Did she simply walk away from everyone she loved? Or did someone make that decision for her?

Only one clue surfaces: the driver, caught on camera. Where is Peggy McGuire?

Her family and friends say they believe they know, and they'd bet the farm on it.

There's a $150,000 reward for information that leads to the missing mother. If you know anything, submit a tip to the Oklahoma State Bureau of Investigation at (800) 522-8017.
