Dozens of people ducked for cover but at least six were shot -- three men and three women.
Yvette McNeal was standing near the shooter when she saw the gun.
"A guy just got trigger happy," she said. "He wanted to shoot, play Rambo and started shooting."
According to police, 38-year-old Gilbert Kibble and 22-year-old Curtis Steward died at the scene.
Felipe Castillo, 26, was rushed to Ben Taub General Hospital where he died.
The three women were taken to area hospitals with gunshot wounds, but investigators said their injuries were not life-threatening.

All six victims were said by their families to be related. Now, their loved ones are preparing to plan funerals.
