The Harris County Sheriff’s Office said the bar was shutting down at 2 a.m. and three security guards were trying to clear everyone out.

“I just heard two gunshots and then we turned around and they were like, “He’s dead, he’s dead. You killed him,'” said one witness who spoke to ABC13.

One man died at the scene and the other was transported to a hospital and is stable.

“Everybody was screaming,” a witness said. “Everybody was screaming and crying. There (were) a couple girls crying. His best friend, two of his friends, were lying by his side crying, saying, ‘Why did you kill my friend? You didn’t have to kill him.'”

The security guard who fired the shots has not been arrested or charged and, according to Sheriff Ed Gonzalez, that decision will be left up to the district attorney’s office.

A spokesperson for the restaurant shared the following statement about the incident:

“A tragic incident occurred at one of our Houston restaurants this morning and we are still gathering details of what happened. Since this is an ongoing police investigation, it would be inappropriate to speculate at this time. We will share additional information when it is available.”

A note on the front door of the restaurant states the restaurant will reopen on Monday morning.
