Brian says he has been living a parent’s worst nightmare since last July, when his teenage daughters, Sydney, 15, and Danielle, 14, vanished while visiting their mother, Michelle, for the summer. Two weeks later, Michelle also disappeared, and Brian, who has full legal custody of the girls, says he believes his ex-wife is hiding them. But Brian’s oldest daughter, Brittany, 19, says she believes the girls ran away so they wouldn’t have to live with Brian, who she claims is overbearing, controlling and abusive -- accusations Brian firmly denies. Dr. Phil brings this father and daughter together for the first time in almost a year in search of answers. Plus, hear from Michelle’s brother, Troy, who says he has twice received videos of Sydney and Danielle. Does he have any idea where they -- or Michelle -- might be? And, see a brand-new video of the girls specifically addressing Dr. Phil. What do they say about the situation? Can Dr. Phil help get to the bottom of this mystery?
