NEW Dionisio Garza III from San Bernardino County, California, has been named as the man behind the gun attack that left two people dead and six wounded. He served four tours of duty in Afghanistan and was discharged from active duty in 2014, and doesn't appear to have a criminal history. Reports suggest he went on a rampage with a high-powered AR15 rifle and shot at bystanders before police gunned him down. Pictures from the scene also show police patrol cars riddled with bullet holes. He killed Eugene Linscomb and critically injured father Byron Wilson (right), who police say was trying to fight back and stop the deadly attack. His father said he was suffering PTSD.
