(AP) — A 21-year-old Lincoln man has been charged with murder in the shooting death of a man at a party.

Michael Arellano was charged on Wednesday in Lancaster County Court with second-degree murder, assault and two weapons counts. Police say Arellano shot Shane Newman to death and wounded another man.

The shootings took place early Saturday morning during a party at Arellano’s father’s house in Lincoln. Authorities say Newman got into an argument with someone outside the house and punched him.

Then, police say, Michael Arellano opened fire in response. Police say Arellano denied shooting anyone after police picked him up about an hour later.

A public phone listing for Arellano couldn’t be found. Online court records don’t list the name of his attorney.
