Sixteen-year-old Darbi has gone missing for the second time, inside a year. She was a victim of sex trafficking after running away at 15, and at 16, has disappeared again. She’s had no contact with either her mother, Janice, in California, or her father, Wayne, in Idaho, for nearly a month. Janice and Darbi’s aunt, Camille, both say they fear she’s once again been caught up in sex trafficking – or worse.

“This young lady is at a real threshold in her life, it’s gonna go either really bad, or it’s gonna take a turn for the better,” says Dr. Phil on Monday’s episode.

As her family and an investigator working on behalf of Dr. Phil follow every lead they have to find the missing teen, he’s been lining up a residential treatment program for Darbi, to help her once she’s been located.

Marcela Rondani, Clinical Director and Licensed Marriage and Family Therapist for Polaris Teen (a structured, therapeutic environment specifically for teens), says her facility is standing by to help.
