ARAPAHOE COUNTY, Colo. — A judge has sentenced convicted murderer Devon Grant-Washington to life in prison plus 102 years for killing a Sudanese immigrant.

An Arapahoe County jury found Grant-Washington guilty in the shooting death of 43-year-old Youn Malual outside the apartment he shared with his wife and five children.

Prosecutors said Grant-Washington, 23, shot Malual at close range in a case of mistaken identity. Malual had immigrated to Colorado to escape the violence of his native Sudan.

Grant-Washington and four others were looking for a rival gang member when they came upon Malual returning from work in the early-morning hours of Dec. 26, 2011. Malual’s wife heard the shots and found his body in his car.

Brandon Jackson, 30, and Amin Elhoweris, 28, were found guilty of first-degree murder in separate trials earlier this year. Both were sentenced to life in prison without the possibility of parole. Urocca Guyton was found not guilty last year in a separate trial.

Bruce Dwayne Roberts, 28, pleaded guilty to being an accessory after the fact with the agreement that he would truthfully testify about others.

The prosecution has filed a motion to revoke the plea agreement and revive the original charge based on an assertion that he did not comply with the terms of the plea agreement.  The resolution of that motion is still pending.
