Stronger security measures could have prevented the Florida video-tournament shooting, a lawyer for some of the victims said Tuesday, adding that he was preparing a lawsuit.

Lawyer Matt Morgan wouldn’t name the defendants of the lawsuit, which he said will be filed in state court later this week – but said it will aim to “hold all responsible entities accountable” for Sunday’s mass shooting that killed two and wounded 11 more.

The negligent-security lawsuit will be filed on behalf of several victims of the shooting, including one person who was hit multiple times when gunman David Katz, 24, opened fire at the Madden 19 Tournament in Jacksonville. Katz killed himself afterward.

The qualifier event for the annual competition was held at the Chicago Pizza GLHF Game Bar inside The Jacksonville Landing shopping mall. Morgan said “the highest level of security” should have been in place at The Jacksonville Landing for the event.

“This event could and should have been prevented had there been the proper safety measures in place,” Morgan said during a press conference.

The attorney cited a previous shooting outside The Landing in January 2017 and a more recent spraying of bullets that hit the window of his office across the street as evidence that a mass shooting at the venue could have been foreseen.

He also pointed out that e-gaming competitions where hefty cash prizes are on the line need to have strong security measures.

“There’s a lot of money, tensions run high, especially when one is eliminated.”

Morgan called Electronic Arts’ decision to cancel its remaining qualifiers for the annual Madden tournament “a positive step in the right direction.”

“That is what we are trying to achieve with this lawsuit,” Morgan said. “Having business-owners take a second look at their security procedures… to ensure the safety of all Americans when we go out into the street.”
