A 68-year-old man was found dead in his burned-out vehicle northwest of Hibbing, Minn., authorities said Monday.

Louis Stewart, of Nashwauk, Minn., was found Friday night by firefighters and Itasca County sheriff's deputies who were called to a fire in an abandoned garage on County Road 8 near County Road 336 in Balsam Township, the Sheriff's Office said.

Stewart's body was found in the driver's seat once the vehicle's fire was extinguished.

Authorities have yet to say what caused the fire.
