RavensChamp and TrueBoy

On August 27, 2018, David "RavensChamp" Katz took part in a Madden NFL 19 tournament held in the Good Luck Have Fun (GLHF) Game Bar in Jacksonville, Florida, which is home of the Jacksonville Jaguars football team.

During the tournament, Katz lost a match ungraciously and, in what could be the worst case of rage quitting ever, went berserk and started firing a smuggled pistol in the direction of other contestants, killing two and injuring eleven before turning the gun on himself. The entire match was streamed on Twitch and the gunshots and ensuing chaos were caught on audio, though the video feed of the contestants cut out moments before the shooting started.

This is the third known mass shooting in recent Floridian times, the first being the Orlando nightclub shooting Pulse gay nightclub shooting in 2016, where 49 people were killed, followed by the Stoneman Douglas High School shooting Marjory Stoneman Douglas High School shooting] in February 2018, where 17 people were killed.

One of the victims, Elijah "TrueBoy" Clayton, was seen with a red laser sight aimed at his chest shortly before the first shots were fired. The other, Taylor "SpotMePlzzz" Robertson, was happily married with a son and was good friends with Clayton on Facebook. Clayton was a big fan of the Jaguars and helped the team reach the quarterfinals in the Madden NFL 17 tournament while Robertson was killed exactly three months before his 28th birthday.

After news of the shooting broke out, EA Sports, the creator of the Madden NFL franchise, cancelled three upcoming tournaments for safety reasons, and pro-Breitbart trolls used the opportunity to mock gamers for allowing the tragedy to happen. In addition, a SWAT team raided Katz's father's home as part of the investigation.
