A crumbling marriage and secrecy about finances led Lewis Bennett to murder his wife, Isabella Hellmann, at sea and then stage her death to look like an accident. Nancy Grace looks at the evidence against Bennett with a panel including forensic psychiatrist Dr. Daniel Bober, forensics expert Joseph Scott Morgan, Atlanta lawyer & juvenile judge Ashley Willcott, and Crime Stories reporter John Lemley. Nancy also visits with songwriter Greer Baxter and Broadway star Mandy Gonzalez about their musical collaboration "Line in the Sand," an inspiring song on the new album "Fandango at the Wall."
