According to the Sheriff's Office, three people were found dead at the scene including the sole suspect, 24-year-old David Katz of Baltimore, Maryland, who died of a self-inflicted gun shot wound. Another nine people were injured by gun fire, and two suffered injuries fleeing the shooting.

The Sheriff's Office is declining to state a motivation for Katz's alleged actions. The Los Angeles Times interviewed a participant in the tournament who said that Katz had been angered after losing a game.

Katz allegedly used at least one handgun in the shooting. The Bureau of Alcohol, Tobacco, Firearms, and Explosives is investigating whether Katz's firearm was legally owned.

A Twitch live stream of the tournament reportedly captured audio of the shooting. One can hear the sound of multiple gunshots, the shouts of what sounds like injured victims, and the chaotic aftermath of the shooting.
