CHEEKTOWAGA, N.Y. (AP) — Authorities say a man who uses a wheelchair has been charged with fatally shooting his 54-year-old father inside the suspect's suburban Buffalo home.

Police in the town of Cheektowaga (cheek-tuh-WAH'-guh) say 31-year-old Sir William Hardy shot and killed William Hardy late Monday night.

Officials say the elder man had just arrived from California when he was shot with a rifle.

Police say the son was in a wheelchair when officers arrived on the scene. Details of the son's physical condition haven't been released.

Authorities say they don't know yet what led to the shooting.

Hardy was charged with second-degree murder and is being held without bail at a Buffalo hospital. It couldn't immediately be learned from Erie County prosecutors if he has an attorney.
