AURORA | A gang member who killed a Sudanese immigrant in 2011 in what investigators say was a case of mistaken identity has been sentenced to life in prison plus 102 years.

Devon Grant-Washington, 23, was convicted Wednesday, June 15, of first-degree murder stemming from the death of 43-year-old Youn Malual in December 2011 in unincorporated Arapahoe County. Judge Frederick Martinez then handed down the sentence immediately after the guilty verdict was announced.

In a statement, prosecutors said Grant-Washington killed Malual as he pulled up to his home just west of the Aurora border because he thought he was a rival gang member. Grant-Washington then fired several shots into the home of a rival gang member, prosecutors said.

Grant-Washington is one of five people charged in connection with the slaying.

Brandon D. Jackson, 30, and Amin Elhoweris, 28, were found guilty of first-degree murder in separate trials earlier this year and 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, prosecutors said, but he did not comply with the agreement and prosecutors said they are trying to revoke it.
