@cbsnews: The trial has begun for Jose Ibarra, the man accused of murdering Laken Riley, a nursing student whose body was found on the University of Georgia campus. Riley's death in February became a rallying cry for some political candidates after it was revealed that Ibarra entered the country illegally. This 911 call was played publicly for the first time during the trial. It came from Riley's phone during the attack that claimed her life. #clarkecounty #georgia #lakenriley
