Calling allegations that a Hawaii couple stole identities of dead babies for unknown reasons unique, a U.S. judge on Monday upheld a previous ruling to detain the pair without bail. According to prosecutors, Walter Glenn Primrose and Gwynn Darle Morrison are the real names of the couple who have been fraudulently living for decades under stolen identities, Bobby Fort and Julie Montague. Prosecutors say Primrose spent more than 20 years in the Coast Guard, where he obtained secret-level security clearance. Primrose and Morrison have pleaded not guilty to conspiracy, false statement in a passport application and aggravated identity theft. Prosecutors have suggested the case is about more than identity theft
