Baytown, Texas detectives can probably close the book on this one after finding that local man Ty Vaughn googled “is it illegal to kill an illegal immigrant” minutes before the January 14th shooting death of fiancee Luis Banos, KHOU reports. Vaughn, 31, blasted Banos, 27, in the face with a bolt-action rifle and then attempted to claim it had been a suicide. After nearly two months of inconsistent statements, prosecutors finally charged Vaughn with murder last week.
