The delegates were in full uniform and worked extra at the Set Night Club, Troy Finner, senior assistant for the Houston Police Department, told reporters at a news conference Sunday.
All three deputies were hit with gunfire while trying to break up a fight in the parking lot after the club closed.
A Spanish man in his twenties opened fire in the crowd, Finner said. The suspect was taken into custody after seeking treatment for a gunshot wound at a hospital in Sugarland and is being questioned about his motive, Finner said.
All three deputies, two men and a woman, have been taken to hospital and are expected to survive. The female deputy sheriff is undergoing surgery Sunday morning but was “in good spirits,” said Houston Sheriff Ed Gonzalez.
A 40-year-old Spanish woman who was hit by gunfire was taken to hospital and died of her injuries. It’s unclear how many people were shooting at this point, Finner said, but the incident is under investigation.
