A witness told CNN that another player told her that one of the shooters was angry that he was defeated in the tournament and momentarily left the scene and went back with a gun and began shooting.

The woman told CNN that the player said there were two shooters and that they had committed suicide at the scene, but those reports are unconfirmed.

The Jacksonville Police Department tweeted a warning to citizens to avoid the area of 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,” it said. “We can’t stress enough to stay away. Many blocks away.”
