A suspect in the shooting of four people, two fatally, at the Masquerade on Nov. 12 has been arrested.

Police said Jonathan Bautista, 23, is facing two counts of murder and two counts of aggravated assault. He was arrested in Social Circle, Ga. The victims were Ewell Ynoa, 21, and Giovan Dia, 22.

The shooting occurred on Sunday, Nov. 12, at a Cousin Stizz show. Atlanta Police said four people were shot, resulting in two deaths. According to police, “The preliminary investigation indicates that the two deceased victims earlier had become rowdy and climbed up onto the stage during the break before the main act appeared. Another patron took issue and an argument ensued. This other patron then drew a pistol and shot the two victims as well as toward the ground, most likely striking the additional victims at this time.”

The suspect didn’t know the four victims. Deputy Chief Darryl Tolleson called it “just a confrontation that went bad” during a press conference about the arrest. Police identified a suspect within 48 hours of the crime.

Tolleson said the Masquerade only had unarmed security and didn’t screen attendees for firearms or have “any type of screening for that matter.” He said the venue sometimes hires off duty officers but did not do so on the night the shooting occurred.

In a statement on Facebook, the Masquerade promised to beef up security for future events.

“Our deepest heartfelt condolences go out to the victims of Sunday night’s tragic act of violence and their families,” the message said. “There are no words to make sense of this. The police investigation is ongoing and we have been working closely with the Atlanta Police Department. Security is our number one priority and we are reviewing our protocols to ensure that all of our patrons are safe at all times. Going forward, there will be an increased security presence on site, including heightened uniformed Police presence at all events. All concerts will go forward as scheduled and we will update as more information becomes available.”
