A witness said Katz lost an intense game, snapped, and started shooting.
Dennis Alston, who was a video game competitor, said he beat Katz Saturday when they played. When he tried to shake his hand after losing, Katz stared blankly back.
Katz is a 2017 championship winner, according to EA Sports.
Williams confirmed that federal investigators are searching Katz' Baltimore residence.
