This Week on the Show

Gabby Petito's father, Joseph Petito, spoke to Dr. Phil about his desperate search for his little girl just days before the heartbreaking news that the FBI recovered a body in Wyoming that they believe is 22-year-old Gabby. In July, Gabby Petito set off from Florida on a cross-country van trip with her fiancé, Brian Laundrie, but two months later, he returned alone. Laundrie has since hired a lawyer, is refusing to speak to Gabby’s parents and the police -- and recently, disappeared. Police revealed the couple had an altercation in the days before Gabby vanished -- and their subsequent interaction with officers was caught on camera.
