WEST GOSHEN, Pa. (KDKA/AP) – Authorities say a recent Pennsylvania high school graduate was shot in the head and killed in a road rage incident.

The Chester County District Attorney’s office says 18-year-old Bianca Roberson was shot by another driver as the two tried to merge into a single lane in West Goshen on Wednesday.

“A red pickup truck merged in at the same time and the man in the pickup truck pulls out a gun and shot her in the head killing her,” Chester County District Attorney Tom Hogan said.

Roberson’s car veered off the road and was later found in a ditch. Investigators say the shooter fled the scene driving down Route 202 in a red pickup truck.

Roberson had just graduated from Bayard Rustin High School. She was headed to Jacksonville University in Florida in the fall.

Hogan calls the shooting a “totally random, senseless act of violence.” Hogan says Roberson’s family is devastated.

“To that person to that man who fired that shot turn yourself in now every second you are out there you are only making this worse for yourself and making this worse for this young ladies family,” Hogan said.
