Four people, including the shooter, are dead following an attack at a Flordia Madden ’19 tournament. News4Jax reports Good Luck Have Fun was thrown in chaos when the shots rang out.

Officers are finding people hiding in locked places and people are urged to stay calm and where they are and not come running out.

“We will get to you. Please don’t come running out,” said JSO via Twitter.

Police urged everyone to stay away from the area because it is not safe.

Witnesses said they saw several people being taken out on stretchers.

Randy Wyse, president of the firefighters union, said Engine Company 1 was training in the area and victims began running up to them before they received the emergency call. He said victims ran as far as the CSX building, about a half mile away to get help.

The wounded victims have been taken to Memorial Hospital, where three victims were in stable condition, and UF Health Medical Center, where there has not been any patient information.

A motive appears to be the fact someone lost a match, pulled a gun, and opened fire.

New: The Jacksonville gunman was a gamer in the Madden tournament who lost, and he killed himself after opening fire, another competitor tells me. https://t.co/6ftAr6vrd3

FYI I’m still trying to get details from other competitors, but they are pretty shaken up by all this, so more info will come when it comes. Sheriff’s department will have a briefing in about half an hour. https://t.co/sGaxcs2kcf

One survivor – who suffered a gunshot wound – tweeted it was the worst day of his life.

I am literally so lucky. The bullet hit my thumb
