SIOUX CITY, Iowa (AP) – A 22-year-old man convicted of shooting a Sioux City police officer has pleaded not guilty to federal robbery charges in a separate case.  Jamal Dean entered his pleas on Wednesday to robbery, conspiracy and other charges. Authorities say Dean, his brother, Levon Dean, and Sarah Berg, of Sioux City, were involved in the 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. Levon Dean and Berg also have pleaded not guilty. The trial for all three is scheduled to begin Feb. 3rd.
