JACKSONVILLE, Fla. — A Baltimore man fatally shot two people and injured nine others Sunday during a video game tournament in Jacksonville, investigators said.
David Katz, 24, then turned the gun on himself, Sheriff Mike Williams said.

Although witnesses have said he was angry about the tournament, Williams did not give a motive as to why Katz started shooting at 1:34 p.m. during the Madden Championship Series competition at the Good Luck Have Fun Game Bar, at the Jacksonville Landing, a popular riverfront destination.
Williams did confirm that Katz was in town for the two-day tournament, but did not say if he was a player.
