This post has been updated to indicate that three people, including the shooter, were killed in the Jacksonville mass shooting event earlier today.
At least eleven people have been shot and three people were killed in a mass shooting attack at a live-streamed competition for the “Madden NFL 19” game at an arcade in Jacksonville, Fla., according to local news reports.
The Jacksonville Sheriff’s office confirmed three people were killed in the attack, including the shooter.
“We just finished clearing The Landing of potential witnesses and victims there,” said Sheriff Mike Williams in a statement broadcast on Facebook Live. “We have no outstanding suspects,” Williams said. “We have one suspect in this case. He is deceased at the scene.”
According to a report in The Los Angeles Times, the shooter was a player who had lost during the competition and then shot other attendees at the event before killing himself.
The event was live-streamed on Twitch and there are multiple audio streams that broadcast the sounds of the shooting live.
Multiple participants in the event took to Twitter to describe the scene.
The sheriff’s office confirmed via tweet that witnesses to the shooting were hiding in locked areas in the shopping area where the event — and shooting — occurred.
“This is a horrible situation and our deepest sympathies go out to all involved,” said Electronic Arts in a statement about the shooting.
In a direct message to The Los Angeles Times, one witness, Steven “Steveyj” Javaruski, said that the gunman had targeted “a few” people and shot at least five before shooting himself.
The event was a Madden tournament with about 250 people in attendance. It was intended to be a competition that would select attendees for a final tournament in Las Vegas.
