Federal and city authorities say the gunman who opened fire outside a Texas bar, killing two people and wounding 14 more was not on their radar before the attack. Both the FBI and police in Austin said Monday that it’s too soon to identify the motive behind the mass shooting early Sunday. The FBI has said it’s investigating the shooting as a potential act of terrorism, coming after the U.S. and Israel launched an attack on Iran. Investigators are poring over thousands of hours of video and police say there are more than 150 witnesses to interview. Austin Police Chief Lisa Davis says the shooter legally bought the weapons several years ago.
