The Biggest Gamble

Christie Wilson was a beautiful 27-year-old woman beloved by her family and friends. One October night in 2005, she spent six hours in a California casino gambling at the blackjack tables with a man she'd just met. Wilson left the casino that night with him and was never seen again. But the casino itself is outfitted with 700 cameras capturing movements of gamblers everywhere. Correspondent Erin Moriarty follows the story and examines the never publicly seen before videotape that may identify a killer.
