Three people died in a mass shooting during a video game tournament at a waterfront shopping complex in the northern Florida city of Jacksonville, police said Sunday.
"There were three deceased individuals at the scene, one of those being the suspect, who took his own life," Sheriff Mike Williams told a news conference.
Nine people were shot and wounded and two others were injured fleeing the scene, he said. All of the injured are being treated in the hospital and are in stable condition.
The suspected shooter, who used at least one handgun, was identified as 24-year-old David Katz from Baltimore, Maryland.
Katz was a participant in the video game tournament and reportedly became angry when he was defeated, according to witnesses.
The shooting occured at a game bar hosting a Madden 19 NFL video game tournament at The Landing entertainment and shopping complex.
About a dozen gun shots could be heard on livestream footage of the popular American football video game before being cut off. In one scene, what appears to be a laser from a gun passes over the body of one of the video game players.
Josh Benson, an anchor with News Channel 8 in Tampa, shared a video of Katz doing an interview after a previous Madden win.
In 2017. Katz had won the Madden 17 for the Buffalo Bills. The NFL team posted a picture of Katz on its Twitter last year.
Electronic Arts, the company that makes the video game, said: "This is a horrible situation, and our deepest sympathies go out to all involved."
