Authorities said an eastern Ohio man fatally shot his 5-year-old son, before turning the gun on himself in an apparent murder-suicide.
Guernsey County sheriff's deputies went to a home just outside Cambridge Wednesday afternoon to check on 36-year-old Russell Ball. They say he had threatened to hurt himself.
Deputies forced their way into the home and found Ball and his 5-year-old son dead. It's believed Ball shot and killed his son and then shot himself with the same weapon.
The sheriff's office continues to investigate.
