CNN reports the shooting happened while the Madden 19 tournament was going on at the GLHF Game Bar. Gunshots were heard during a Twitch stream of the tournament. In a press conference, Jacksonville Sheriff Mike Williams said that the suspect, a white male, is dead but they are still working to identify him. Sheriff Williams also said that they "finished clearing the Landing of potential witnesses and victims" and have "no outstanding suspects."
The Jacksonville Sheriff's Office Twitter page was one of the first social media pages to report the shooting.
"Mass shooting at the Jacksonville Landing. Stay far away from the area. The area is not safe at this time. STAY AWAY #TheLandingMassShooting," read a tweet from the Jacksonville Sheriff's Office warning people in the area. They later said there were "multiple fatalities" and "many transported" away from the scene.
Prior to the press conference, the police said they were searching the area for people hiding and encourage anyone in The Landing to call 911 and stay hidden until the SWAT team finds them.
EA Sports, the publisher behind Madden 19, released a statement following the shooting. "We are aware of an incident at a sanctioned Madden Championship Series competition in Jacksonville," the company said. "We are working with authorities to gather facts at this stage. This is a horrible situation, and our deepest sympathies go out to all involved."
