In Part 2 of this Dr. Phil mystery, the family of 14-year-old Dylan Redwine, who has been missing for three months, continues to search for answers. Dr. Phil sits down one-on-one with Dylan's father, Mark, in an effort to help find Dylan. Was he the last person to see the teen? And, what does Mark think happened to his son? Mark says he’s tired of having the finger pointed at him, and he’s willing to take a polygraph test to help clear his name.
