San Antonio gunman who killed 2 and injured 5 argues self-defense and promotes his Instagram account


A 19-year-old Texas man promoted his Instagram account while claiming self-defense following his arrest for allegedly fatally shooting two people and wounding five others at a San Antonio bar during a concert. 

Kiernan Christopher Williams, 19, was arrested Monday and faces capital murder charges for the Sunday night shooting at the Riverwalk bar called Ventura in San Antonio.   

In a video obtained by by KSAT, Williams can be heard promoting his Instagram account while he was being taken into custody by police, saying to reporters, ‘Don’t worry about me, I’m gonna be aight, you all gotta follow me on Instagram’ and adding that he’s ‘an upcoming artist.’

The shooting occurred at a concert which Williams was scheduled to perform at on Sunday night, according to a promotional poster that he had posted on his Instagram account. 

The two men who died in the shooting were identified as Robert Jay Martinez, 20, and Alejandro Robles, 25. 

A woman, 46, and four men, ranging in age from 16 to 19, were also injured during the shooting and are expected to survive, police said. 

Williams told reporters that he was acting in self-defense when he opened fire during the bar concert.  

‘He told me he was gonna kill me,’ Williams said of one of the people at the venue. ‘He told me cause I bumped into him, he was gonna kill me.’

‘I regret everything that I did, no lie,’ Williams said.

Police said in Williams’ arrest affidavit that witnesses told investigators they that they had seen Williams fighting with one of the victims before the shooting occurred, according to News 4 San Antonio.

Police also said that a witness also claimed that Williams shot one of the victims ‘intentionally’ and that the Williams ‘continued to fire his weapon into the crowded venue causing several victims to be struck by gunfire.’  

Police have said the shooting was ‘not a random incident’ and that at least one of the seven victims knew Williams.

‘It’s nothing more complicated than an argument that occurred inside the club with someone pulling out a firearm,’ San Antonio Police Chief William McManus said Sunday night.

Robles, who was killed in the shooting, had gone to Ventura with his wife to support a childhood friend who was performing that night, family members told the San Antonio Express-News. His father, James Huff, said he did not believe his son knew Williams.

A since-deleted Facebook event indicated Sunday night’s concert at the Ventura was ‘Living the DREAM,’ a showcase featuring multiple performers, and the Express-News reported that a flyer listed Williams as one of the scheduled performers. An email to the apparent promoters wasn’t immediately returned.

Authorities said that the investigation into the shooting is still ongoing.  

Jail records do not list an attorney who could speak on Williams’ behalf. 

Court records obtained by MySanAntonio indicate that Williams pleaded no contest to a charge of assault f a public servant causing bodily injury in 2017. 

He was jailed on multiple occasions for probation violations, until being released from the state prison system in August 2019, according to those records. 

Williams’ Instagram account features multiple videos and photos of himself singing while holding a gun. It’s unclear if that gun was the one that was used during the bar shooting.
