Who is the Jacksonville Shooter? David Katz Was Prominent Competitive Video Gamer

David Katz, a 24-year-old from Baltimore, has been identified by the Jacksonville Sheriff's Office as the single suspect in the Jacksonville, Florida, shooting on Sunday. Katz reportedly used a handgun to kill two people Sunday afternoon and injure 11 others before killing himself.

Katz opened fire on a video game tournament at Jacksonville Landing, a downtown entertainment complex. He was reportedly a prominent member of the gaming community, and had won the same tournament the previous year. It's not clear whether he was personally associated with anyone participating in this year's tournament, and a possible motive is not known.

The FBI raided the Katz family home near Baltimore's Inner Harbor neighborhood Sunday night and remain in the location.

The Madden NFL video game tournament at GLHF Game Bar was being broadcast live on gaming platform Twitch, and sounds of gunfire and screams could be heard by those watching before it was taken off the site a few minutes after the attack.

Jacksonville authorities immediately put the area under lockdown and sent in SWAT teams to perform a "methodical search" of the location.

Governor Rick Scott said Sunday that he had offered the Jacksonville Sheriff's Office any state resources they might need. President Donald Trump was briefed on the shooting and was following the developments, according to White House press secretary Sarah Huckabee Sanders.

As of August 26, there had been 232 mass shootings in the United States this year.

According to the FBI, 17 of the 50 active shooter incidents in 2016 and 2017 occurred in commerce areas, with 85 killed and an additional 98 wounded. All of these events involved a male, single shooter.

This story is breaking and will be updated as more information becomes available.
