In July of 2003, 30-year-old Heather DeWild vanished after visiting her soon-to-be ex-husband Daniel DeWild's home. From the beginning, Heather's family suspected Daniel of harming her, especially when they learned he was angry about having to pay child support for his and Heather's two children. Investigators soon focused not only on Daniel, but also his identical twin brother, David. While Daniel was not forthcoming, investigators were convinced David had something to say, but could police break through their tight twin bond? What could cause a person, or persons, to destroy their family? Erin Moriarty takes you even deeper into the "48 Hours" investigation, "The Devil's Twin".
