(FOX 11) - One of the fatalities has now been identified as Southern California native, Elijah Clayton.
In the gaming world he was known as "True"... sometimes True-boy. In life, videos show him playing games like Madden 19 and saying things like, "My favorite part of the game is running the football." And, Elijah Clayton - often called Eli - was highly regarded in the virtual world of gaming. He had a reputation of being a guy people liked.
He attended Calabasas High School in 2014, but for the three years before that he went to Chaminade College Preparatory High School where classes on this Monday started with a sober announcement on the PA system.
15-year-old Drew Dalton didn't know Clayton. But, like all of the students at school today he knew Clayton was one of the gamers killed in Jacksonville, Florida over the weekend.
The 9th grader says announcement was made on the Chaminade loudspeaker at the start of school. Says Dalton, "They said he was shot in the shooting in Jacksonville and everyone was quiet and, like, prayed for him." He says hearing that had a big impact on everyone on campus.
School officials described Elijah as a young man who always showed respect for his peers and the faculty.
And, for his mother, the school's statement read: "... our hearts are breaking as we contemplate the impact of this senseless loss on her... The entire Chaminade community is earnestly praying for Elijah's family during this difficult time."
But, even students who didn't know him - who arrived at the school after he moved to Calabasas were affected by his death.
Tina Cheng is a senior. She came to the school after Clayton left Chaminade. She was shaken by the violence.
She tells FOX 11 of the mass shooting, "I just think its so not right and I'm afraid of my own safety because I think anything could happen... anywhere."
Chaminade student Aidan Pizziano was watching the competition online when all heck broke loose. Pizziano puts it this way: "I was actually watching it and yeah. The cameras cut out but I just heard stuff." The "stuff" he heard were the gunshots that killed Clayton another gamer known as "Spotme" and injured others.
When he heard the gunshots Pizziano says, "it was scary."
It was scary for Chaminade parents too. Shannon Dalton told FOX 11, "I was horrified because both of my kids were gamers and I would worry if my kids were at one of those tournaments and it's just really sad."
Thea Pizziano, Aidan's mom, told us, "It's pretty sad what this world is coming too... I'm afraid to let my kids out of my sight."
At Calabasas High School the principal said, "He was amazingly kind hearted. He was a contributing member of our campus."
