CUMBERLAND, Ohio >> Authorities say an 85-year-old man fatally shot his son in what authorities believe was self-defense during a domestic dispute in Ohio.

The Zanesville Times Recorder reports Guernsey County sheriff’s deputies said the victim’s mother called 911 Friday night, saying her 64-year-old son was intoxicated and threatened to kill her.

Sheriff’s Lt. Sam Williams said the son began firing at his 84-year-old mother while she was talking to the dispatcher and her husband retrieved a rifle and returned fire, fatally wounding his son.

The son died shortly after deputies arrived at the family’s home near Cumberland, about 80 miles east of Columbus.

The sheriff’s office says investigators believe the fatal gunshot was fired in self-defense, and the father was released from custody.

No charges were filed.
