Two people are dead and five injured after a person opened fire "indiscriminately" at a San Antonio bar Sunday night.
San Antonio Police Department responded to a shooting at a bar called Ventura, steps from the San Antonio River, at 8 p.m. local time. An altercation appears to have broken out between customers when one person pulled out a gun and began shooting, Police Chief William McManus said at a press conference Sunday night.
In total, seven people were shot. A 21-year-old man died inside the club, while a second person in critical condition was later pronounced dead.
Five people are currently being treated at area hospitals. Their conditions are unclear at this moment, police said.
All of the victims appear to be patrons, McManus said. No employees of the bar were shot.
On Monday, police said they had arrested Kieran Christopher Williams, 19, in connection to the shooting and will be charged with capital murder.
Williams responded to questions from reporters at the police station after being taken into custody
"He told me he was gonna kill me," Williams said. "He told me because I bumped into him he was gonna kill me. Don't worry about me, I'll be all right."
Williams also referred to himself as an up-and-coming music artist and requested people follow him on Instagram just before being loaded into the back of a police vehicle.
"I regret everything that I did," he added.
The police chief had hinted on Sunday that they expected to make an arrest quickly.
"We're working on that, I'm confident that we will identify the individual and have that person in custody sooner than later," McManus said.
The concert, called Living the DREAM, featured a lineup of up-and-coming rappers popular on social media.
