The man who carried out the deadly rampage at a video game tournament in Jacksonville Sunday was a competitive gamer who won previous Madden tournaments, News 4 Jax reports.
David Katz, 24, of Baltimore died of a self-inflicted gunshot after authorities say he opened fire on a video game tournament at Jacksonville Landing, a popular entertainment complex downtown.
According to Jacksonville Sheriff Mike Williams, Katz was the sole gunman in the shooting, which claimed three people and wounded nine others.
A short time later, he was found dead inside the shopping center after turning the gun on himself, authorities said.
Williams said Katz used at least one firearm to carry out the shooting. Sources tell the news station it was a semi-automatic handgun.
On Sunday evening, federal agents raided Katzs family’s home in the Federal Hill area of Baltimore.
Katz is listed on EA Sports’ website as a Madden 2017 championship winner. He went by the gaming name “Bread,” CNN reports.
Katz is seen pictured in a tweet by the Buffalo Bills after the team sponsored the “Madden 17” Championship in Feb. 2017.
“Congrats to David Katz, the Madden 17 Bills Championship winner! Thanks for following along, Bills fans,” the tweet read.
Katz reportedly trashed talked his competition in an interview with former Buffalo Bills player Steve Tasker, saying “I think personally I’m one of the better players.”
