A 28-year-old Navy veteran and gym manager from Colorado was among the 59 people killed when a gunman opened fire on concertgoers in Las Vegas Sunday night.
Christopher Roybal's death was confirmed Tuesday by an employee of Crunch Fitness on North Academy Boulevard, where Roybal worked.
Roybal was at the Route 91 Harvest Festival with his mother, Debby Allen, who survived the shooting. Allen said it was the "saddest day" of her life.
"I was trying to run towards where I thought he (Christopher) might be, but a man wouldn't let me. He pulled me away and said, 'You can't run towards the gunfire.' I knew it. He would have never not called me instantly to tell me he was OK," Debby Allen told CBS Las Vegas.
Allen was posting frantically on Facebook at the time of the shooting, sharing that she was safe but could not find her son.
At 11:42 p.m. Sunday, she posted, "I am safe. I just can't find Christopher Roybal anywhere. He's not answering anyone's phone calls." She commented about an hour later, "God help me."
Roybal grew up in Corona, Calif., and later moved to Denver, working in Colorado Springs. He had served in the Navy in Afghanistan.
"While the senseless events in Las Vegas have impacted many across this nation, today the tragedy hit home when we learned of the tragic death of one of our community members, Navy veteran Christopher Roybal," Colorado Springs Mayor John Suthers said in a written statement. "Our hearts go out to Christopher's family, friends and his co-workers at Crunch Fitness as well as the military community, as we grieve this loss."
Friends set up a GoFundMe page on Roybal's behalf, and 493 people already had donated more than $26,000 in the day after it was created, $11,000 more than its goal.
Flo Bradley, one of Allen's Facebook friends, posted that she was "heartbroken" for Allen and her family.
"He fought for this country as a Navy Veteran and to die enjoying a Country Music Concert on the home-front is sad, disgraceful, horrific, tragic, unfair, maddening," Bradley wrote.
