OMAHA, Neb. (AP) — An Omaha 18-year-old has been given 15 to 22 years in prison for shooting to death a friend.

Christopher Spears was sentenced on Tuesday in Douglas County District Court. He’d been convicted of manslaughter and weapons use after pleading no contest. Spears originally was charged with second-degree murder. Prosecutors lowered the charge in escape for Spears’ pleas.

Prosecutors say Spears was 17 when he shot 17-year-old Dominique Hollie in February last year. Prosecutors say the shooting happened after Spears made sexual comments about Hollie’s sister, prompting Hollie to go to his bedroom and grab a sawed-off shotgun that he later returned to his room. Prosecutors say that after an argument, however, Spears went to Hollie’s room, returned with the shotgun and shot Hollie in the face.
