Two people were killed when a gunman opened fire at a marketplace in downtown Jacksonville, Fla. during an EA Sports Madden football gaming tournament, according to the Jacksonville Sheriff's Office.
Elijah Clayton and Taylor Robertson were killed in the shooting.
Nine people suffered gunshot wounds and two were injured fleeing the area, according to Jacksonville Sheriff Mike Williams. Williams added that those victims were all in stable condition and sent to local hospitals.
The Jacksonville Sheriff’s Office confirmed there was a "mass shooting" and urged citizens to stay away from the area.
The shooting took place at the GLHF Game Bar at the Jacksonville Landing, a mall along the St. Johns River.
The shooter is believed to be David Katz, a 24-year-old gamer from Baltimore, Maryland, who was in Jacksonville for the tournament at the GLHF Game Bar, according to CNN. Katz brought the gun into the venue on Sunday and opened fire before turning the gun on himself and taking his own life, according to Williams. There are no outstanding suspects and no possible motive was established for Katz.
Katz used the name "Bread" throughout the gaming community and won Madden tournaments in 2017, also according to CNN.
“We are deeply saddened at the incident and pray for everyone involved," Jacksonville Landing said in a statement. "The Jacksonville Landing is fully cooperating with the Jacksonville Sheriff's Office and all ongoing investigations.”
The complex also includes restaurants, with the GLHF Game Bar being billed as "Jacksonville's home for gamers and nerds alike."
In a live Twitch video, it shows two people playing Madden during a tournament before more than a dozen shots rang out, with patrons screaming in the background.
Jacksonville Jaguars owner Shad Khan released a statement after the shooting.
"It's impossible to comprehend today's news. I'm heartbroken for the families and friends of the victims and can only express my deepest condolences as we try to understand why and how this can happen, not only here, but anywhere," Khan wrote. "What I can say is I know today what lifelong Jacksonville residents have known forever - we are resilient, compassionate and remarkably supportive of our neighbors and friends, particularly in the most trying occasions. This tragedy will ask the best of all of us, but I know we will respond."
