Anthony S. Dunn, 21, a lifelong area resident who was a 1978 graduate of Winston Churchill High School in Potomac, died Sunday at Suburban Hospital as a result of injuries he sustained in an auto accident earlier that day.

Mr. Dunn was a student at the University of Delaware, where he was studying international affairs. He was home for the weekend to attend the Washington Redskins football game at RFK Stadium in Washington.

A spokesman for the Montgomery County Police said that Mr. Dunn was eastbound on Democracy Boulevard in Bethesda on Sunday morning when he ran off the road and struck a utility pole. Police said they believe that Mr. Dunn fell asleep at the wheel.

A passenger in the car, 19-year old Neal Edward Perkins of Landenberg, Pa., is listed in good condition at Suburban Hospital, a hospital spokesman said. A family friend said that Perkins is a college friend of Mr. Dunn.

Mr. Dunn was born in Washington and reared in Potomac. During his years at Churchill High, he played on the varsity soccer team. Churchill won the county championship during one of those years. Mr. Dunn also had been active in several area soccer teams over the years.

Survivors include his father and stepmother, H. Stewart and Loti K. Dunn, two brothers, Christopher T. and Timothy P., a stepbrother, Rhett Savage, and a stepsister, Elizabeth Savage, all of Alexandria, and a grandmother, Marguerite Hoovler of Chevy Chase.
