Gamer Eli “TrueBoy” Clayton has been identified as one of three people killed during a video game tournament on Sunday.

The 22-year-old was a former high school football player from California with a love for the game, according to CNN. NBC News reports the shooting yielded three fatalities. In a video clip depicting the moments before the shooting, Clayton was seen being targeted by the attacker as a red laser went across his chest.

"Elijah's family wants you to know that he was a good man. He did not believe in violence. He never even had a fistfight. He loved football and out of all the video games he could play — he settled and mastered Madden. He made a good living gaming and he saved his earnings so he can afford to go to college to continue his education,” Brandi Pettijohn, his cousin, said in a statement.

Clayton’s alma mater tweeted its condolences.

Principal of Calabasas High CJ Foss remembers Clayton fondly.

"He was amazingly kind hearted. He was a contributing member of our campus,” Foss told KABC. "When it hits this close to home, it's going to be especially difficult.”

The gaming world and Clayton's friends have been publicly grieving on social media.

The other person killed was identified as 27-year-old Taylor "SpotMePlzzz" Robertson. The gunman, David Katz, killed himself at the scene, according to CBS News.
