These are the victims of the Jacksonville shooting

Eli “Trueboy” Clayton and Taylor “SpotMePlzzz” Robertson were killed after a gunman attacked an esports tournament in Jacksonville, Florida, on Sunday, according to localmediareports.

Law enforcement officials have not yet confirmed the victims’ identities, though family members and friends have spoken out about their deaths.

Competitors were participating in the southern qualifier of EA Sports’ “Madden 19” championship series, a video game football tournament, at the Jacksonville Landing shopping mall when a gunman opened fire, killing Clayton and Robertson, and injuring nine others. The suspect died of a self-inflicted gunshot wound. Two others were injured fleeing the scene.

Clayton, 22, was a frequent competitor at Madden events and was described by EA Sports as “consistently one of the best.” Clayton was entering the second round of the tournament when shots began to fire.

Shay Kivlen, the 2018 Madden Bowl Champion, posted a tribute to Clayton on Twitter, describing him as “one of my best friends in life.”

“You were one of the most kind and genuine people I’ve ever met,” Kivlen wrote. “I love u like a brother. I’m gonna miss hearing you laugh everyday and seeing your genuine smile.”

Robertson, 27, of Ballard, West Virginia, was a former champion, having won the Madden 17 Classic tournament in 2016. EA Sports described Robertson, who won 72 percent his matches, as the “toughest opponents in competitive Madden.”

He began playing Madden when he was 10 years old, but only began playing competitively in recent years. He was excited to fly to Jacksonville, tweeting days earlier that it was “time to chase that second belt.”
