Fairfax County police have identified a woman killed in a crash in McLean last week as 52-year-old Cheri Cusumano.

The McLean woman was traveling on Lewinsville Road shortly after noon last Tuesday when she apparently lost control of her Toyota minivan near Swinks Mill Road and struck a tree, police said.

The vehicle rolled back on to the roadway where it caught fire, police said. Cusumano’s body was found inside the charred vehicle.

Police said it remains unknown whether speed, alcohol or a medical condition played a role in the wreck. The investigation is continuing.
