Police on Tuesday identified a 21-year-old man as the suspect who opened fire inside a crowded Colorado supermarket in an attack that killed 10 people, including an officer, and sent terrorized shoppers and employees scrambling for cover.
Authorities said Ahmad Al Aliwi Alissa was from the Denver suburb of Arvada and that he engaged in a shootout with police inside the Boulder store. The suspect was being treated at a hospital and was expected to be booked into the county jail later in the day.
Investigators have not established a motive, but authorities believe he was the only shooter, Boulder County District Attorney Michael Dougherty said.
