Mass shooting at Madden Championship Series event in Florida leaves several dead

At least eleven people have been shot and four people were killed in a mass shooting attack at a livestream event debuting the new “Madden NFL 19” game at an arcade in Jacksonville, Fla., according to local news reports.

The Jacksonville Sheriff’s office confirmed on Twitter that one suspect was dead at the scene and the police were still investigating.

“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.
