It is believed heavy rains contributed to a fatal car wreck last night in State Road.  Patricia Wood Hemric of Mt Pleasant Road was traveling north on Hwy 21 near Crestwood Cemetery when her vehicle collided with a tractor-trailer in the southbound lane.  Witnesses report that it looked like she hydroplaned or swerved and then lost control on wet roads.  Hemric died at the scene.  The truck driver was not injured.  The NC Hwy Patrol is still investigating the accident.
