(AP) — The Nebraska Supreme Court has rejected a request for post-conviction relief by a man serving life in prison for the fatal shooting of a 16-year-old boy.

Jason Marks was convicted in 1994 of the drive-by shooting of 16-year-old Arthur Godbolt. Police say Marks was 18 when he engaged in a shootout with a rival gang member. Godbolt, who was standing nearby and not armed, was hit in the head by a bullet Marks fired.

Marks’ motion for postconviction relief accused the judge and prosecutor in his case of misconduct. Marks also alleged his trial attorney was ineffective.

Prison inmates file postconviction relief motions once they have exhausted all other appeals.

On Friday, the state’s high court rejected Marks’ motion, saying there was no merit to his claims.
