One person was injured Monday around 2:45 p.m. in this one-vehicle accident on Interstate 20. Robert Crump was reportedly driving eastbound on I-20 near mile marker 49 when his vehicle allegedly suffered a mechanical failure and entered the median, according to an eyewitness at the scene. The white Monte Carlo SS then rolled on its side an unknown number of times, coming to rest in the left westbound lane. Crump was uninjured. However, his sole passenger, Heuy Williams, was treated at the scene for unknown injuries and transported off-scene by Advanced Emergency Medical Services. No other vehicles were involved in the accident, but multiple witnesses stopped to help. Minden Police, Webster Parish Sheriff's deputies and Troop G state troopers were at the scene.
