Stephen J. Toth, 20, a student at the Germantown campus of Montgomery College and a 1979 graduate of Gaithersburg Senior High School, died Sunday from injuries he received in a highway accident early Sunday morning.

Montgomery County Police said Mr. Toth, a pedestrian, was struck by a vehicle on Connecticut Avenue near Dean Road in Wheaton. He was taken to Suburban Hospital in Bethesda where he was pronounced dead.

Mr. Toth was born in Detroit and moved to the Gaithersburg area at an early age. After graduating from Gaithersburg High, he enrolled in Montgomery College, where he was pursuing a degree in electromechanical engineering at the time of his death.

He had worked part-time for several years at the Gaithersburg Lumber Yard and this summer was working at Pel-Bern Electric, Inc. in Rockville.

While in high school, he was active in sports. He had been a member of the Boy Scouts of America.

Survivors include his mother, Elizabeth E. Toth, of Gaithersburg; a brother, Attila, also of Gaithersburg, and three grandparents, Mrs. Sofia Toth, of Bethesda, and Mr. and Mrs. Joseph Gyorik, of Washington.

The family suggests that expressions of sympathy be in the form of contributions to Boy Scout Troop 231, c/o Charles Ferrell, 227 Rolling Road, Gaithersburg, or to the Hungarian Memorial Chapel, c/o the Hungarian Freedom Fighters Federation, Inc., P.O. Box 3091, Washington, D.C. 20009.
