Police say a 12-year-old boy jumped from an overpass above Interstate 66 in northern Virginia and fell onto a car, killing the driver.
The incident took place Saturday afternoon in Fairfax County. Virginia State Police spokeswoman Corinne Geller said in a statement Sunday afternoon that the boy landed on a Ford Escape and the impact incapacitated the vehicle's driver.
Geller says the driver of the Ford, 22-year-old Marisa W. Harris of Olney, died at the scene.
The statement says the front-seat passenger steered the vehicle off the interstate and the car came to a stop on the left shoulder. The front-seat passenger wasn't hurt.
The boy was taken to a local hospital for treatment of life-threatening injuries.
In a statement, Towson University spokesman Ray Feldmann said: "The entire Towson University family is deeply saddened by the tragic loss of our alumna, Marisa Harris. Marisa was a caring, giving person who intended to devote her life to helping children in crisis. We also send our thoughts and prayers to the family and friends of the injured 12-year-old boy. This is a horrific tragedy that will forever impact the lives of everyone who knew, loved and admired Marisa."
