A Vicksburg man and his wife were killed Monday when the Chevrolet Equinox SUV they were in collided with an 18-wheeler’s flatbed trailer at the intersection of Clay and Levee streets.

Cecil Langley, 85, was pronounced dead at the scene by Warren County Coroner Doug Huskey, Vicksburg Police Officer Russell Dorsey said. Langley’s wife, Mary, was taken to Merit Health River Region Medical Center and later transferred to University of Mississippi Medical Center in Jackson, where she died Monday night, Huskey said.

L’Terrance Blakely of York, Ala., the driver of the 18-wheeler was not injured.

Dorsey said witnesses told officers at the scene Langley was westbound on Clay Street at a high rate of speed, ran the stop sign and collided with the trailer on Levee Street as the truck was attempting to make a left-hand turn onto Clay. The impact of the collision pushed the front of the SUV under the trailer.
