Franklin County Sheriff’s officers found a Princeton man unconscious outside a burning house Monday night.

The man, 44, who owned the house at 102 High St., refused medical treatment once he was taken to safety, said Lt. Curtis Hall, a sheriff’s spokesman.

Hall said officers were called to the two-story house around 9:20 p.m. Monday. The Ohio Township Fire Department then fought the blaze.

Investigators believe it was an electrical fire, and a damage estimate was not yet available Tuesday morning, Hall said.

Princeton is about 8 miles south of Ottawa, just off U.S. Highway 59.
