Dr. Phil speaks exclusively to 21-year-old Erin Caffey, who is serving two life sentences plus 25 years for plotting a brutal attack on her family that left her mother and two younger brothers dead. In the early morning hours of March 1, 2008, two intruders, armed with a .22-caliber pistol and a samurai sword, entered the family’s home and killled Erin’s mother, Penny, and brothers, Matthew, 13, and Tyler, 8, before setting the house on fire. Her father, Terry, suffered multiple gunshot wounds but managed to escape through a window and crawl to a neighbor’s house. Authorities say that Erin, who was 16 at the time, conspired with her boyfriend, 19-year-old Charlie Wilkinson, and two others, Charles Waid, 20, and Bobbi Johnson, 18, to kill her parents -- because they didn’t approve of her relationship with Charlie. For the first time, Erin speaks out about what happened that night. Did she really want her family dead? Or, was she the victim of puppy love gone terribly wrong? Plus, Terry opens up about the horrific ordeal. Why does he say he’s forgiven everyone involved? And, does he believe his daughter’s account of what happened? As Dr. Phil pokes holes in Erin’s story, will Terri change his mind about his daughter’s role in the killings? Don’t miss this explosive two-part series!
