Crystal McDowell is still missing nearly 2 weeks after she vanished just before Hurricane Harvey hitting her Texas town. The last person known to have seen the 37-year-old realtor and mom of 2 -- boyfriend Paul Hargrave -- talks to Nancy Grace about her disappearance. Baytown, Texas, newspaper reporter Matt Hollis, forensic psychiatrist Dr. Daniel Bober and radio host David Mack also join the discussion. Nancy and guests also ask: Did too much cold medicine cause a husband to murder his wife in his sleep? A North Carolina man says he woke up to find his wife stabbed to death and he thinks the medicine made him kill her.
