15 years ago, Christie Wilson vanished from Thunder Valley Casino. Her body has finally been found.

In the early morning hours of Oct. 5, 2005, 27-year-old Christie Wilson left Thunder Valley Casino after a night of gambling. She wasn't alone. When a missing persons report was filed, Placer County investigators immediately pulled surveillance footage from the casino northeast of Sacramento. They watched Wilson, under no apparent duress, enjoying herself like any other patron. Then, they spotted a man who kept striking up conversations with her, hour after hour. Around 1 a.m., the man and Wilson left together. The last bit of surveillance footage showed them walking out into the parking lot.
