A crazed driver shot and killed a teen honor student who aspired to one day work for the FBI during a road rage incident in Pennsylvania this week, according to reports.

Bianca Nikol Roberson, 18, had just left a local mall — where she was shopping for college clothes with her mother and grandmother Wednesday — when she and a man driving a red pickup tried to merge into the same lane on a highway in West Chester, ABC 6 reported.

“And a man in the red pickup truck pulled out a gun and shot her in the head, killing her,” Chester County DA Tom Hogan told the station.

Roberson’s car veered off the southbound lanes of Route 100 in West Goshen Township and crashed, according to the report.

Highway cameras reveal that Roberson and the driver of the truck, possibly a Chevrolet, got into an altercation just before the incident. An image released by the West Goshen Township Police Department shows the suspect’s vehicle — and the victim’s — on the lower left side of the frame.

“They were jostling for a position or whatever,” West Goshen Police Chief Joe Gleason told ABC 6. “And unfortunately this gentleman took it to a degree that was just unconscionable.”

After shooting Roberson, the driver fled on Route 202 before exiting onto Paoli Pike. Cops say he is blond, between 30 and 40 years old and has a medium build.

Roberson’s grandmother was sitting in the backed-up traffic after the crash, and thought, “I hope it’s not Bianca,” the station reported.

Roberson was a recent graduate of Bayard Rustin High School in West Chester, where she was on the honor roll. She planned to attend Jacksonville University in Florida in the fall — and hoped to someday solve cases for the FBI.

“If you don’t even think it was your fault, and have a conscience, come forward and give us some closure and explain in your own words what happened,” her father, Rodney Roberson, told the station.
