Three people are in critical condition after a shooting at Topgolf, a place known for being a family-friendly entertainment destination.

The shooting at Topgolf left customers and employees shaken and closed down the business 4 hours early Saturday night.

"The manager came and they were like we are asking everybody to close their tabs and to leave now," Christina Perez said. “You need to evacuate immediately.”

Perez was with her family and friends enjoying a night out when shots rang out just before 9:30 p.m. leaving customers in the dark.

“We asked [staff], 'well why?'” Perez said. "What happened, and they were like, ‘we can't say, everybody just leave.'"

Perez says she heard rumors of a shooting and knew something was wrong when she saw three ambulances in the parking lot.

San Antonio Police Chief William McManus says they believe an argument broke out in the parking lot after someone asked the driver of a truck to slow down.

He says several people jumped out of the truck and shots were fired during a big fight.

One victim was shot in the chest; the other two were shot in the back, according to McManus.

A spokesperson with Topgolf confirmed all three of the victims are employees with the company. The victims are Hector Beattle, Brian Flores and Matthew Davis. According to a Topgolf employee the men are between 21 and 28 years old.

All three victims were taken in to University Hospital in critical condition.

A witness says the shooting happened in the parking lot where employees often take smoke breaks.

Police later arrested Mario Guerra, 22. He is facing three charges for aggravated assault. According police, charges may be pending against others.

Topgolf released a statement Sunday:

"We are deeply saddened to hear about the incident last night. The safety and well-being of our Associates and Guests is a top priority, and we are cooperating with local authorities."

Perez calls the latest shooting a sad reality that’s becoming a new normal.

"Every time we go somewhere, like I have little kids, I am anticipating something could happen,” Perez said. “We have to be prepared, we have to know where the exits are.”
