Last Seen Alive Season 1 Episode 4 Shattered Lives

More than a week has gone by since Brianna Kraemer left her Tucson school, stepped into a car, and vanished. It's not the first time the 15-year-old has disappeared. Last time, Brianna was lured away by a dangerous local family who had her selling drugs on the street, and Brianna's parents believe the family is once again involved. The couple's private investigator, Kelly Townsend, starts by planting a GPS tracker on one of the suspect's vehicles. From there, the chase is on.
