The Oconee County coroner says a sheriff's deputy has died after he was pinned between his patrol car and a tree.

Coroner Karl E. Addis told multiple media outlets that 26-year-old William Frederick Schuck III of Rabun Gap, Ga., died Sunday morning. Addis said Schuck died of traumatic asphyxiation.

Schuck had been patrolling a private dirt road near Highway 11 north of Walhalla when his car got stuck. When he got out of the car to assess his situation, the car apparently moved forward and pinned him to the tree.

Investigators say Schuck had spoken with his wife after 1:30 a.m. and told her his car was stuck. When his supervisor could not reach him on the phone or radio, officers began searching for him. He was found dead at 3 a.m.
