(Vienna, Va.) (Fox News) — A 22-year-old woman was killed when a 12-year-old boy attempting suicide by jumping off an overpass in Virginia landed on her car Saturday afternoon.

Virginia State Police said Marisa Harris of Olney, Md., was driving east on Interstate 66 when the boy landed on top of her Ford Escape.

While the boy’s jump left Harris “incapacitated,” he survived and was being treated for life-threatening injuries at Inova Fairfax Hospital.

Harris’ boyfriend, who was sitting in the SUV’s passenger seat, steered the car to the side of the road, police added. Harris died at the scene.

Harris’ family members told WRC she was a graduate student at Marymount University in Arlington, where she studied clinical counseling.

Police are investigating the incident as a suicide.
