Jesse Van Wallene, 29, told NBC News he found himself around 15 feet away from the shooter when he stopped at a red light and spotted him with a "large gun in his hand."
"He was in full gear so he didn't seem like a civilian, but there was no writing on any of the equipment," the restaurant server said. "It seemed like he was wearing a bullet-proof vest and he was wearing a helmet with a clear visor over his face."
An officer reportedly shot the man when he began firing at Austin Police headquarters.
The police activity shut down Interstate 35 for several hours, and cops are still investigating whether the man had additional explosives—per KVUE, "Police said they believe the suspect died, but due to the nature of a potential bomb, officers are using "extreme safety" while dealing with the person."
