The owners of the Colorado Springs LGBTQ nightclub targeted in a mass shooting say the gunman entered the property wearing a military-style flak jacket and was carrying "tremendous firepower," a report says. 

Matthew Haynes and Nic Grzecka revealed the detail after reviewing surveillance footage of the attack that unfolded late Saturday at Club Q, according to the New York Times. 

"One customer took down the gunman and was assisted by another," Haynes told the newspaper, describing how the shooting came to an end. "He saved dozens and dozens of lives. Stopped the man cold. Everyone else was running away, and he ran toward him." 

Haynes said in an interview that the alleged shooter, identified as 22-year-old Anderson Lee Aldrich, pulled up to the nightclub in a strip mall wearing a military-style flak jacket and showcased "tremendous firepower," the New York Times reported.

"He’s never spent money on a credit card or ID ever scanned in our business that we know of," he told ABC News. "I think this was a community of target for him."
