Ahmad Al Aliwi Alissa, 21, of Arvada, Colorado, United States purchased a Ruger AR-556 at Eagles Nest Armory in Arvada on March 16, 2021. It is a variant of the Ruger SR-556, an AR-15 style semi-automatic rifle manufactured by U.S. firearms company Sturm, Ruger & Co. also known as Ruger.
In September 2014, Ruger announced the Ruger AR-556, which uses traditional direct impingement action. It was produced to compete with the Smith & Wesson M&P15 Sport and other AR-15 models.
Alissa passed a background check when he bought a Ruger AR-556, a senior law enforcement source told CNN. Using the rifle, he fired at the King Soopers grocery store in Boulder, Colorado on March 22, 2021.
“We are absolutely shocked by what happened and our hearts are broken for the victims and families that are left behind,” Eagles Nest Armory owner John Mark Eagleton told the publication. He said his gun shop will continue to fully cooperate with investigators.
“Ensuring every sale that occurs at our shop is lawful, has always been and will always remain the highest priority for our business,” Eagleton stated. “Regarding the firearm in question, a background check of the purchaser was conducted as required by Colorado law and approval for the sale was provided by the Colorado Bureau of Investigation.”
With the Ruger AR-556 bought at Eagles Nest Armory, Alissa killed 10 people including Boulder Police Department officer Eric Talley, 51, and King Soopers employees Teri Leiker, 51, Rikki Olds, 25, and Denny Stong, 20. The other victims were Jody Waters, 65, Lynn Murray, 62, Kevin Mahoney, 61, Kevin Mahoney, 61, Suzanne Fountain, 59, Tralona Bartkowiak, 49, and Neven Stanisic, 23.
