The man accused of opening fire at a video game tournament on Sunday, killing two people before turning the gun on himself, had a troubled home life and regularly clashed with his mother over his apparent obsession with video games. Police have not released a motive.
"Hes a well-known competitor", said one gamer to WFOX-TV, who claimed to have beaten Katz on Saturday.
"[He was here] all weekend", said the gamer. He had shades on, he didnt speak to anybody. "He didnt say anything".
He says Katz wasn't known to trash talk with rivals. An FBI official in Baltimore confirmed that its agents were searching the family home of the man authorities said they believe was behind the attack. David Katz was hospitalized at least twice, but Daniel Webster, who directs the Johns Hopkins Center for Gun Policy and Research, says his treatment wasn't enough to disqualify him.
A video of the shooting that is now being examined by investigators captured a red dot that appeared to be a laser pointer trained on a player, according to the Associated Press; the player was identified by attendees as Clayton.
Police arrived on the scene within two minutes of receiving the first emergency calls at 1:34pm, Sheriff Williams said.
"@SirusTheVirusTV and @fitzmagic13 dad are heroes", said pro "Madden" player Jokeeee.
A report has emerged about Katz's character from a previous gaming tournament in which he was introduced with the words "he's not here to make friends".
The game's maker, EA Sports, lists a David Katz as a 2017 championship victor.
In a post-game interview following his win, Katzs face could be described as emotionless, while his eyes wander from looking at the floor to around the room. In several "listening sessions" after the shooting, Mr. Trump seemed to show support for proposals including strengthening background checks, restricting access to weapons for the mentally ill and raising the age for purchasing some firearms to 21. The stream then ends abruptly as gunshots are heard ringing out. "He was a really good person, one of the nicest guys you'd ever meet". Virginia is an open-carry state, but Wiltshire said if any attendee brings a gun - even with their concealed carry permit - they will not be allowed in the venue.
Jacksonville Sheriff Mike Williams told a news conference Monday that 24-year-old David Katz, of Baltimore, "walked past patrons who were in other parts of the business and focused his attention on the gamers".
