Kristen Galvan was a typical 15-year-old girl, a good student, in JROTC and on the drill team. 

Then, Galvan began a relationship with a 17-year-old boy. That boy, Galvan's mom says, was a recruiter for a sex trafficking ring. Galvan ran away with her boyfriend. She was found by police turning tricks on a notorious Houston street.

After Galvan was rescued, she told her mom about the threats made against the family. As her recovery continued, Galvan earned cellphone privileges again. During a holiday trip with family, Galvan disappeared.

Robin Cory says her daughter, missing three years now, has been trafficked again.
