1. The Suspect Lost in the Madden Tournament & ‘Targeted a Few People’ Before Shooting Himself, Witnesses Say

A witness told the Los Angeles Times that the shooter, identified as David Katz, had played in the tournament earlier and lost. Steven “Steveyj” Javaruski, who was another competitor in the tournament, told the newspaper the gunman came back to the event with a gun and “targeted a few people” before fatally shooting himself.

Another witness, Javaris Long, told the Tampa Bay Times that the suspect was “nerdy” and got mad because he lost, so he went to his car, got his gun, came back and “started blasting everybody.”

Drini Gjoka, another one of the gamers, tweeted, “I am literally so lucky. The bullet hit my thumb. Worst day of my life. I will never take anything for granted ever again. Life can be cut short in a second.”

Police said the suspect was the lone shooter. There had been initial reports that there may have been another suspect but that was quickly ruled out. Police said Katz was the only suspect and after shooting a dozen people, he turned the gun on himself.

A source told Fox News that Katz “reacted to losing with violence.”

The winner of the Jacksonville tournament was set to win $5,000 and a chance to advance to Las Vegas where the prize pool was over $100,000. Two players defeated Katz during the two-day Jacksonville tournament, which started with pool play on Saturday and continued with a single elimination bracket on Sunday, a gamer told WJAX-TV.

“He says he tried shake alleged shooter’s hand yesterday after their game, alleged shooter stared blankly. Says shooter was acting ‘weird’ and wearing same clothes as yesterday,” WJAX reporter Ryan Nelson tweeted.

David Katz, playing using the nickname Bread, won the Buffalo Bills Madden Club tournament in February 2017, according to the EA Sports website. He won $10,000 during that event. You can watch one of the games from that 2017 tournament below:

Katz played another game in the Madden Club Series Championship later in 2017 after advancing through winning the Bills tournament. He lost that quarterfinals game against Misery. It was played in Burbank, California, on April 15.

Katz says in the 2017 video that he typically played on PS4. He was at times ranked among the top players in Madden Ultimate Team, but social media posts from fellow gamers posted both before and after the shooting show he had a reputation for cheating and shady play, including intentionally making games “glitchy” to his advantage.

Katz would also post strategies and tips on YouTube, Twitch and elsewhere, including a now-defunct website called “The Gamers Lab.” Disturbing old tweets about suicide on “The Gamers Lab” Twitter account from 2017 led many on social media to connect Katz to the site, saying he was the one tweeting. But “The Gamers Lab” posted Sunday denying that he operated the account, “Fyi this was not HIS account. I think he may have posted some youtube videos on the madden tips channel years ago. Thoughts and prayers to the victims and the families/friends.”

4. Court Records Show Katz, Who Bought the Guns From a Licensed Dealer in August, Had ‘Significant Medical Problems & Needs’ & Was Hospitalized for Mental Illness

Police have not commented about how the gunman acquired the gun used in the shooting. It is also not clear how the shooter got into the gaming bar with the gun and whether there was any security, including metal detectors or guards, at the event.

He was armed with two semi-automatic handguns during the shooting, police said. According to authorities, he had a a .45 caliber and a 9mm along with extra ammo. One of the guns was equipped with an aftermarket laser sight, police said. Jacksonville Sheriff’s Department Chief Mike Williams said only one of the guns was used by Katz. According to the ATF, both of the guns were bought within the month of August in Baltimore from a licensed dealer.

Police found the shooter’s vehicle near the scene and were approaching it with caution in case there were explosives inside, WESH-TV reports. There are no reports of explosives being found in the car, but it is not yet known if any other evidence was located inside the vehicle.

Police would not comment about his motive. They said it is believed he had stayed in the Jacksonville area Saturday night, but they are looking for more information about when he came to the city. By Sunday night, the JSO confirmed earlier reports; investigators had found Katz’ car but were left with more questions than answers.

“We have located and impounded the suspect’s vehicle and a search is pending. We believe he stayed somewhere locally last night. If anyone has information about where he stayed, please contact 904-630-0500 or JSOCrimeTips@Jaxsheriff.org”

In court records obtained by Heavy, his parents, mother Elizabeth, a toxicologist who worked at the Food & Drug Administration and now works at the Health & Human Services department earning around $107,000 a year, and Richard, a engineer employed by NASA earning around $146,000 annually, divorced in 2007. At the time, their two sons, Brandon now 28, and David, 26, both had “significant medical problems and needs,” court records show.

The reason their health problems were made known in court records had to do with a dispute between their parents on health insurance coverage. Not to get in the weeds with the incongruous court decision, suffice to say that some of the sons’ medical bills were “extraordinary.” It’s noted that at the time their mother sought to have the divorce decree modified and have insurance coverage amended, both Brandon and David were adults and considered emancipated, the records read, but were still, documents show, described as children under their parent’s care.

According to additional court records from the divorce obtained by The Associated Press, Katz was twice hospitalized in psychiatric facilities as a teenager and was prescribed anti-psychotic and anti-depressant medications. “The records show Katz’s parents disagreed deeply on how to care for their troubled son. Katz’s father claimed his estranged wife was exaggerating symptoms of mental illness as part of the couple’s long-running and acrimonious custody battle,” the AP reports.
