MILLBORO, Va. (AP) — As Virginia state Sen. Creigh Deeds lay in a hospital with stab wounds apparently inflicted by his son, police are investigating what could have led to the violent encounter.

By many accounts, Creigh Deeds and his 24-year-old son had a close relationship. Gus Deeds left college to help his father's 2009 campaign for governor. A Bath County neighbor says he can't fathom why Deeds apparently stabbed his father before killing himself.

Authorities are still piecing together a motive but they suspect that is what happened Tuesday morning at the Deeds home in Millboro.

Deeds was in fair condition at a hospital in Charlottesville.

State police investigators are expected to update their investigation on Wednesday.
