Kelly says on August 2, 2011, he found his wife of more than five years, Margaret, dead in their bathtub. Police ruled her death an accidental drowning — but Margaret’s friends, Nancy and Christine, say they think she was murdered by Kelly, and they want the investigation into Margaret’s death reopened. Kelly admits his marriage wasn’t perfect but insists he did not murder his wife. What does he claim happened on the day Margaret died? Kelly says Nancy and Christine have been harassing him, and he believes they even hired someone to throw a caustic substance in his face. Sparks fly when the women face Kelly for the first time in nearly two years on Dr. Phil's stage. Do Nancy and Christine have any evidence that Margaret’s death was suspicious? And, hear from homicidal drowning investigator Andrea Zaferes, who was contacted by Margaret’s friends. Does she believe this was an accidental drowning or something more sinister? Plus, Kelly agrees to take a polygraph test.
