LINCOLN, Neb. (AP) — The Nebraska Supreme Court has upheld first-degree murder and weapons convictions and the life sentence of a western Nebraska man.

Jason Custer was convicted and sentenced last year in Cheyenne County District Court for killing 35-year-old Adam McCormick, of Sidney, in November 2012.

Prosecutors say Custer shot McCormick at a Sidney house after the two men argued over $160 in drug money.

In his appeal, Custer argued prosecutorial misconduct, that there was not enough evidence to convict him, and that the trial court gave faulty jury instructions and excessive sentences.

The high court rejected those arguments and amended the sentence only to reflect that credit given for 508 days already served by Custer applied only to his weapons convictions, not his life sentence.
