A 40-year-old South Riding woman was killed Monday when her Subaru sedan was forced off the road and struck a tree, Virginia State Police said.

Elena Brunetti was driving east on Route 50 near Willard Road when the accident occurred shortly before 7 a.m., according to Sgt. Tom Martin, a police spokesman.

Martin said Jeffrey Shouse, 36, who was driving a 1996 Dodge pickup in the left-hand eastbound lane, veered into Brunetti's lane, nearly striking her car and causing her to run off the road.

Brunetti's car spun off the shoulder, and the driver's door struck a tree, Martin said. She was pronouned dead at the scene.

Martin said Shouse, of Haymarket, has been charged with reckless driving. Fog and rain reduced visibility and contributed to the accident, Martin said.

Brunetti's father, James Brunetti, of Winchester, said his daughter was going to work at a Sprint telephone company office when she was killed. She had planned to work Monday and take the rest of the week off to prepare for the holidays, he said.

"She was going to spend the better part of the holidays with us," James Brunetti said. "We were going to go to church and have a special Christmas Eve dinner."

Brunetti said his daughter was single and loved cats and gardening. "All I can say is she was a wonderful daughter," he said.
