A 91-year-old Prior Lake resident is dead after a 3-car pileup on Highway 13 in Scott County Wednesday evening. A Toyota Corolla driven by Florence Bothof of Prior Lake was heading southbound on 13 when it went to turn onto Franklin Trail at just after 5:30pm and was struck by a northbound Ford Focus. Both vehicles then hit a Cadillac CTS that was stopped at the stop sign on Franklin Trail. Bothof was pronounced dead at the scene. The other drivers suffered non life-threatening injuries.
