An eyewitness described a man wearing a green shirt and a grayish handkerchief around his neck firing into the food area with what looked like an assault rifle.[1] Another witness reported a white man in his early to mid-30s firing a rifle that was “able to shoot three to four shots a second”.[8] Jack van Breen, the lead singer of the local band TinMan, which was doing an encore when the shooting began, told KPIX-TV he heard someone shout, "Why are you doing this?"; the gunman's response: "Because I’m really angry."[9]
