Investigators are trying to determine whether or not a shooting at a bar in Austin, Texas, that has left at least three people dead and dozens injured was the result of an act of terrorism or an individual with mental illness, according to people briefed on the matter. NBC News’ Priscilla Thompson reports that investigators say it’s still too early to solidify a conclusion and the gunman’s potential terrorism ties.
