Jacob Mitich had just made it to Round Two of the Madden NFL 19 tournament in Jacksonville when shots rang out.
Mitich was one of 10 people injured on Sunday during the Esports competition. Three people died, including the shooter.
Now, 23-year-old Mitich is filing a lawsuit against the game developer that held the tournament, the pizza parlor that hosted the event and the mall where it was located.
Mitich and his attorney filed suit in circuit court in Duval County on Thursday.
Mitich's attorney, James Young with Morgan & Morgan in Jacksonville, told the Associated Press that the lawsuit alleges negligence.
There was no off-duty officer at the event, which hosted over 100 people, he said. The mall had a private security guard, and she was spotted in the pizza place before the shooting, but Young said it's unclear where she was during the shooting.
On Wednesday, Jacksonville fire inspectors shut down Chicago Pizza.
A city code violation report says the restaurant didn't have a permit to hold the Madden NFL 19 tournament. Also, The Florida Times-Union reported that the restaurant's last approved building layout was submitted in 2009.
Fire inspectors said the layout was altered without approval to create the GLHF Game Bar, the room where the tournament took place.
