Al Issa, 21, was named by Boulder Police Chief Maris Herold during a press conference on Tuesday morning, with Herold announcing he had been charged with 10 counts of first-degree murder.
The suspect, from nearby Arvada, was shot in the leg and wounded after police arrived at the King Sooper store, and was taken to hospital, where his condition was stabilized.
Al Issa is said to have opened fire at the crowded grocery store in southern Boulder as shoppers and workers ran for cover.
His victims ranged in age from 20 to 65, and included Boulder Police Officer Eric Talley, 51, a married father of seven who was first on the scene.
Herold said there is currently no motive for the shooting. She refused to confirm that video of a man being taken away by police with a bloodied leg was Al Issa, with the suspected murderer due to be booked into jail later on Tuesday.
Al Issa is said to have lived in the US for most of his life, with investigators saying they believe he operated alone, and that there is no further danger to the public in connection to the supermarket massacre.
An emotional Herold on Tuesday also named the 10 victims, whose ages ranged from 20 to 65. Herold identified the victims as Denny Strong, 20, Neven Stanisic, 23, Rikki Olds, 25, Tralona Bartkowiak, 49, Suzanne Fountain, 59, Terri Leiker, 51, Eric Talley, 51, Kevin Mahoney, 61, Lynn Murray, 62, and Jody Waters, 65.
The visibly-distressed police chief said: ‘Our hearts go out to all the victims killed during this senseless act of violence….I feel numb, and its heartbreaking.
