Police in Jacksonville, Florida have confirmed multiple deaths in a shooting at the GLHF Game Bar, a gaming and pizza venue at a local mall, which was hosting a Madden NFL 19 competition and livestreaming on Twitch at the time.

Reports are somewhat inconsistent for the moment, but at least two people were killed besides the gunman, identified as 24-year old Baltimore, Maryland resident David Katz. According to Variety, the two victims were apparently 22-year-old Elijah “TrueBoy” Clayton and 27-year-old Taylor “Spotme” Robertson. More than 10 other people were also injured.

Although no motive has been formally established, witnesses told The LA Times that Katz was deliberately targeting other competitors after being eliminated from the competition. The event was a regional qualifying round for the EA-sponsored Madden Championship Series, with a final scheduled in Las Vegas and a first-place cash prize of $25,000. Katz had previously won a similar competition in 2017.

Audio of the shooting was captured in the livestream, but THIS IS A WARNING BEFORE YOU CLICK PLAY THAT IT’S DISTURBING AND MAYBE YOU SHOULDN’T.

“Our most heartfelt sympathies go out to the families of the victims whose lives were taken today and those who were injured,” EA said in a statement on Twitter. “All of us at Electronic Arts are devastated by this horrific event, and we also join the community in thanking the first responders who were quickly on the scene.”
