According to the Hubbard County Sheriff’s Office, a caller reported a semi tractor-trailer driving carelessly on U.S. Hwy. 71 at 5:48 p.m. Oct. 25 in Arago Township, north of Park Rapids. While responding, deputies received a report that the semi had pulled into the Leading Edge Mechanical business and was now on fire.
