Yesterday, several people were left dead while others were injured following a mass shooting at a video game tournament in Jacksonville, Florida.
The suspect has been named by police as gamer David Katz, a 24-year-old from Baltimore, Maryland.
Katz is believed to have crashed out of the Madden NFL video game tournament in the Florida city and reacted by opening fire at fellow gamers and bystanders.
He was the Bills Cup Series winner last year and reportedly opened fire after losing a game, this year. Three people, including the gunman, were killed and 11 were wounded by gunfire.
