LINCOLN, Neb. -- A Lincoln man has been found guilty of fatally shooting a man last year. 

Ryan Long was found guilty Tuesday of manslaughter and weapons charges. 

According to court documents, Michael Whitemagpie was shot in a Lincoln alley in 2020. 

Police were called to the area and found Whitemagpie dead alongside 16 spent shell casings. 

Their investigation led to Long. 

The documents say witnesses and video surveillance led police to believe Long and Whitemagpie had been in an argument before the shooting.

He will be sentenced next month.
