Online court records don't list an attorney for 54-year-old Lee Atwood, of Irwin.
He was in custody awaiting arraignment Tuesday on charges including first-degree murder, aggravated assault and reckless endangerment in the death of 46-year-old George Williams.
Trooper Stefani Plume says Williams was shot by Atwood after Atwood went to a residence in South Huntingdon Township to collect a debt.
Plume says the men argued before Williams punched Atwood in the face. Police say Atwood then left, but returned to shoot Williams.
Williams is from the Yukon area of South Huntingdon Township, several miles away from the residence where he was shot in the same township, sometime after 9 p.m. Monday.
