The Loudoun County Sheriff's Office says Mars, who turns 74 Thursday, was driving a Porsche SUV in Aldie on Friday when it crossed the center line and hit a minivan. The sheriff's office says 86-year-old minivan passenger Irene Ellisor of Huntsville, Texas, was not wearing a seat belt and died at the scene.
A Mars spokesman says the tragedy has left Mars "filled with sorrow for the loss of life" and the injured. Mars is the company founder's daughter and has been ranked by Forbes Magazine as the world's seventh richest woman.
The Commonwealth's Attorney is reviewing the matter.
