A single vehicle crash in Andrew County overnight Wednesday injured two from Kansas City. 20 year old Zion W Thornton was on I-29 southbound, just north of St Joseph, when he traveled off the road, crossed the median into the northbound lanes, struck guardrail, causing him to overturn. The vehicle continued down an embankment. Thornton was taken to Mosaic Life Care in St Joseph and then later transported to KU Medical Center. His passenger, 20 year old Marquel D Pettite-Pilgram was also taken to Mosaic Life Care.
