Christopher Roybal, A Navy combat veteran who had served multiple tours in Afghanistan is among those killed in the attack on the Route 91 Harvest country music festival Sunday. Roybal, 28, died in Las Vegas just a few days shy of his birthday, said David Harman, owner of the gym that Roybal managed. Roybal moved to Colorado Springs early this year when Harman opened a new Crunch Fitness location. He worked for the company about three years. “The reason we hired him on was his discipline and his work ethic,” Harman said. “He wasn’t somebody who reported problems. He solved them.”
