At 3pm on December 18, 2011, 23-year-old Phoenix Coldon got in her card and left her family home. Her parents thought she was going to a convenience store and then to a friend’s house. She was expected home later that night, but has never been seen again. But there are lots of clues to suggest that Phoenix is alive and is out there somewhere. This two-part series investigates what happened to Phoenix: did she get fed up with her life and leave on purpose? Was she kidnapped and forced into the sex trade? Or did she die the day she vanished?
