WEST CHESTER, Pa. — A preliminary hearing for a Pennsylvania man charged with fatally shooting an 18-year-old woman during a road rage encounter has been postponed.

Tuesday’s hearing for 28-year-old David Desper, of Trainer, was postponed at his attorney’s request until Aug. 17.

Police say Desper and Bianca Roberson were engaged in a high-speed “cat-and-mouse game” as both tried to merge into a single highway lane before Desper allegedly shot Roberson in the head and drove off June 28. Her car crashed into a tree. Desper surrendered to police a few days later.

Chester County prosecutors didn’t opposed the postponement. Defense attorney Daniel McGarrigle refused to discuss it.
