Margaret Noel Broumas, 24, who was killed Wednesday when she was struck by a vehicle on New Hampshire Avenue in Langley Park, had worked with handicapped children for many years and was employed at the Centers for the Handicapped in Silver Spring at the time of her death.

Prince George's County police said Miss Broumas was running across the street to catch a bus when she was hit by a southbound pickup truck. She was pronounced dead at Prince George's General Hospital.

She was born in Bad Kreuznach, Germany, when her father, Army Lt. Col. Andre George Broumas, was stationed there. The family moved to the Washington area in 1967 when he was assigned to the Office of the Joint Chiefs of Staff in the Pentagon and to the State Department. Col. Broumas was killed in Vietnam in 1969.

Miss Broumas' survivors include her mother, Eugenia P. Bourmas, of Chevy Chase, where the family lives; a sister, Mamie, who is a student at Vassar College in Poughkeepsie, N.Y.; a brother, Andre George Jr., of Chevy Chase, and two grandparents, Mr. and Mrs. Anthony E. Palaologos, of Palm Springs, Calif., and Youngstown, Ohio.

The family suggests that expressions of sympathy be in the form of contributions to Walden Resources, 2401 Blueridge Ave., Wheaton.
