A semi driven by 56 year old Randall Roth of Lake Lillian was traveling north on Highway 9 in Clontarf Township in Swift County yesterday morning, when he saw deer in the roadway and swerved to avoid them. The semi went into the ditch, which caused it to roll over and land on its passenger side. The driver was trapped and then extracted by the local fire department. Assisting in the call were personnel from Lifelink, Benson Police and Fire Departments, and Swift County. Roth was taken to St. Cloud Hospital with non-life threatening injuries.
