Four years ago, 15-year-old Kristen Galvan ran away from home. Kristen’s mother, Robyn, claims an up-and-coming Houston rapper lured her daughter with promises of nice things and pretty nails. After a desperate two-week search, police found her little girl on a Houston street notorious for prostitution. Two months later, Kristen disappeared again, drawn into the dark world of child sex trafficking. She’s now been missing for three years.
