A man convicted of shooting a Sioux City police officer has pleaded not guilty to charges in a separate case.
Twenty-two-year-old Jamal Dean entered his pleas this week to robbery, conspiracy and other charges. Police say Dean and two others were involved in a gunpoint robbery at a Sioux City home in April.
A few days later Dean shot Sioux City officer Kevin McCormick during a traffic stop. McCormick returned to work two weeks later.
Dean was convicted and sentenced to 25 years in prison.
His robbery trial is scheduled to begin February 3rd.
