JACKSONVILLE, Fla. -- Multiple people were killed in a shooting during a video game tournament in downtown Jacksonville, Florida on Sunday.
In a news conference after the shooting, the Jacksonville Sheriff's office confirmed the suspect, described as a white male, was dead and that there were no outstanding suspects. Officials said they believe the gunman was 24-year-old David Katz, who had been a participant in the tournament.
Authorities said that three people were fatally shot during the attack, including the shooter, who died of a self-inflicted gunshot wound. About a dozen others were injured, including 9 people who were shot and others who were hurt fleeing the scene, officials said. The surviving gunshot victims were reported in stable condition at local hospitals.
The shooter used "at least one handgun" to carry out the attack, according to the Sheriff's office.
The attack occurred during the Madden 19 Tournament at the GLHF Game Bar, according to the Twitter of CompLexity Gaming, one of the event organizers. The Landing is an open-air marketplace with stores, bars and restaurants in downtown Jacksonville along the St. Johns River.
The sheriff's department released several tweets warning residents and visitors throughout the incident:
"Mass shooting at the Jacksonville Landing. Stay far away from the area. The area is not safe at this time. STAY AWAY #TheLandingMassShooting," the Jacksonville Sheriff's Office said on Twitter.
On an online stream of the Madden event posted to the website Twitch, several loud gunshots can be heard and the game abruptly stops. After several gunshots, people scream and one person cries out, "Oh (expletive), what'd he shoot me with?" The stream did not show the shooting.
'I'm still shocked'
The event was the Southeastern Qualifier for the Madden NFL Championship Series for Madden NFL 19, according to the bar's Facebook page. "This is your chance to earn your spot in the first Major's Live Finals happening in October 2018. Don't hesitate to secure your spot," the post read in part.
Ryan Alemon, who came from Texas to participate in the gaming tournament, said he ducked down and ran toward the restroom when he heard the gunshots. He stayed there for about 10 minutes and then ran from the scene.
"I'm still shocked, I can hardly talk," he said.
Sheriff Williams said the area had been cleared of witnesses and asked that people do not come downtown because of the size of the crime scene.
Malik Brunson said he was at a nearby Hooters restaurant when the shooting occurred.
"All I heard was he got a gun and the shooting started. One of the man ran into Hooters with the shot wounds, they locked us in the restaurant," he said in a social media message.
CompLexity Gaming Founder and CEO Jason Lake said one of their gamers, a 19-year-old who goes by Drini, was shot in the thumb but managed to escape and is going to be fine. Lake told CNN that the shooting may make the growing eSports industry reconsider security at events.
"To have someone walk into an event like this that's all about good sportsmanship and teamwork and just good vibes, and do something like this, it's heartbreaking," he said. "I think the eSports industry as a whole is going to have to step back and take a look at further strengthening our security."
President Donald Trump has been briefed on the situation, White House press secretary Sarah Sanders said.
Federal law enforcement officials are monitoring the situation in Jacksonville. The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is responding to the scene in Jacksonville Landing, a law enforcement source told CNN.
