This episode originally aired in 2024

When 13-year-old Bianca Piper got into an argument with her mother, Shannon Tanner, over doing the dishes, Shannon put her in the car, drove her a mile up the road, and told her to walk home. While this may seem like an odd form of punishment, it was actually something that had been recommended by Bianca’s therapist. But on March 10, 2005, Bianca never made it home.

Investigators in Foley, Missouri performed an extensive search but uncovered almost no clues regarding the missing girl. Over the years, they’ve investigated many theories, including the possibility of Bianca’s disappearance being related to those of other children in Lincoln County. Was Bianca abducted by a stranger, or was the reason behind her disappearance closer to home?

Anyone with information regarding Bianca Piper’s disappearance is urged to submit a tip through the Lincoln County Sheriff’s website or through their tipline at 636-462-6513.
