Elizabeth Anne Gordon, 22, a 1980 graduate of St. John's College in Annapolis who planned to study nursing, was killed Saturday in a traffic accident near Warrenton, Va.

Virginia State Police said Miss Gordon was driving south on U.S. Route 29 when her car went out of control and turned over in the median strip of the four-lane highway. They said she was thrown from the car into the North-bound lanes, where she was struck by two other vehicles. A passenger in Miss Gordon's car, Stephen Franklin Taft, received minor injuries.

Police said neither of the northbound cars stopped and that the accident is still under investigation.

Miss Gordon, who was born in Jacksonville Fla., lived most of her life in the Washington area. She attended Gordon Junior High School and graduated from the Field School. She began her college career at the St. John's campus in Annapolis, spent two years at the school's campus in Sante Fe, N.M., and then returned to Annapolis for her senior year. At the time of her death, she was working as a nursing assistant for a physician and planned to study nursing.

Miss Gordon was a member of the D.C. Suns, a women's soccer team in the Washington League, and had appeared in an education videotaped program to teach basic soccer skills.

Survivors include her parents, John and Marie Gordon, and a brother, Bruce, all of Washington, and two grandparents, Mr. and Mrs. Thaddeus Biser of Frederick, Md.

The family suggests that expressions of sympathy be in the form of contributions to the St. John's College Athletic Program, Annapolis, Md., 21401.
