In an update to the story from March 4, 2006, titled "The Highest Stakes", as correspondent Erin Moriarty reports, the investigation shifted dramatically when casino surveillance video surfaced, showing Christie leaving the casino with a mystery man. Wilson is dramatically captured on tape leaving the casino and walking into the parking lot with a 54-year-old man named Mario Garcia. She walks out of the frame with Garcia leaving her exact whereabouts in those last few critical moments a mystery. The cameras do show Garcia driving off, apparently alone, moments later. Garcia speaks to 48 HOURS' Moriarty in a network exclusive about his violent past and his interactions with Christie Wilson that night. Is he innocent or is he hiding something deadly? And what will he say to Moriarty under intense questioning?
