Westbound I-20 traffic was stop and go for several hours Friday after a one-car crash near mile marker 96 took the life of Lisa Marie Munn, 25, of Camden. The S.C. Highway Patrol reported Munn drove a 2007 Honda Acura onto the median between the westbound and eastbound lanes and struck a “low boy” trailer the patrol said was legally parked. The patrol reported Munn was trapped in the vehicle and had to be extricated and was dead at the scene.
