Disappeared - Season 4 Episode 7
Vanished in Vermont

Seventeen-year-old Brianna Maitland found life on her parents’ remote farm boring, so in the fall of 2004, she transferred high schools to be with her friends. But after a short while, Maitland dropped out and couchsurfed with help from friends and boyfriends. With no consistent place sleep each night, it took four days for her family to realize she had gone missing. After numerous searches and an extensive investigation, the Maitlands are left to wonder what really happened to their daughter. Police think it all points to foul play, while others speculate that the teen was taken.
