“The person the initial altercation started with, they knew each other,” McManus said.

The shooting occurred during a concert, McManus previously said.

As Williams was being taken into custody, he told reporters the shooting was done in self-defense.

“(Martinez) told me he was going to kill me,” Williams said. “He told me because I bumped into him, he was going to kill me.”

He also promoted his Instagram account before apologizing for what happened.

“I regret everything I did, no lie, I do,” he said.

Williams was set to perform at the venue that night, according to his Instagram account.

Martinez was found dead in the bar with a gunshot wound to his chest. Robles, who was shot once in the back, was rushed to the hospital, but died of his injuries within hours.

Williams has a criminal history that includes a conviction for assault on a public servant.
