Police say he walked into the Walmart in Thornton and randomly began shooting people in the checkout area. Authorities have not disclosed a motive.
He’s charged with killing 52-year-old Pamela Marques, 66-year-old Carlos Moreno and 26-year-old Victor Vasquez.
He is also charged with 30 counts of attempted first-degree murder and committing a crime of violence.
