News4Jax is learning more about the gunman.
Jacksonville Sheriff Mike Williams said the shooter is David Katz, 24, of Baltimore.
Here's how commentators at a previous gaming tournament described Katz:
"Man, David Katz keeps to himself. He's a man of business. Here's not here for the experience. ... He's not here to make friends. He's all business, he's focused. To even get him to open up to you to talk about anything is like pulling teeth."
Katz, a competitive gamer who went by the handle Bread, won the Madden NFL 17 Bills Championship tournament. He was registered to play in this weekend's Jacksonville event.
According to Baltimore Sun crime reporter Justin Fenton, court records linked to Katz's parents' divorce indicated he had "significant medical problems and healthcare needs."
