(AP) — A judge has sentenced a Council Bluffs man to prison his part in a 2011 killing in Omaha.

Douglas County District Court Judge Joseph Troia sentenced 42-year-old Corey Brooks to a minimum of 56 years in prison in the shooting death of 50-year-old James Asmus. The sentence means Brooks will be eligible for parole in 28 years.

Brooks was convicted of manslaughter in the killing as well as drug and gun charges.

Before he was sentenced, Brooks apologized to the Asmus family and asked the judge for leniency.

Two other men were charged in the shooting.

Asmus was found shot to death on Sept. 2 in a south Omaha garage. Prosecutors say a plan by Asmus to rob Brooks may have prompted the shooting.
