Original story: Four people have been killed and multiple others injured after a mass shooting at a Madden 19 tournament in Jacksonville, Florida today. The tournament was being held at the GLHF Game Bar in Jacksonville Landing, an entertainment and shopping area in downtown Jacksonville. The event was also being livestreamed on Twitch when the shooting occurred. According to the Jacksonville Sheriff's Office, one suspect is dead at the scene.

The stream showed two competitors playing Madden, at which point multiple shots and screams can be heard from off-camera (this footage has now been removed by Twitch). One tournament player for pro team comPlexity tweeted that he had been shot in the thumb.
