A video gamer killed two people and wounded several others on Sunday when he opened fire with a handgun at a tournament that was being streamed online from a restaurant in Jacksonville, Florida, police said.

Jacksonville Sheriff Mike Williams named the shooter as David Katz, 24, of Baltimore and said he was in town for the competition. He declined to comment on what led to the third major mass shooting to hit Florida in the last two years.

Williams said Katz killed himself after the shooting and that his body was found along with those of his two victims.
