A 37-year-old Lemmon, South Dakota man was killed when he rolled the semi tractor he was driving after apparently trying to avoid some deer.
The Corson County sheriff says Terry Wiesinger died of his injuries in the accident that happened Monday night east of Keldron on Highway 12.
According to the investigation, he applied the brakes to avoid the animals and the truck rolled. It was not pulling a trailer.
