Judith L. Hayes, 22, a student at Prince George's Community College and an employe of Manor Care nursing home, died Friday at Prince George's General Hospital in Cheverly of injuries she received in an auto accident earlier that day.

Maryland State Police said that Miss Hayes had been driving on a ramp leading from the outer loop of the Beltway to Rte. 1, northbound, when she struck a light pole. There were no other persons in the auto.

Miss Hayes was born in Cheverly and lived in Greenbelt before moving to Berwyn Heights. She was a graduate of Bladensburg Senior High School and was studying business administration at Prince George's Community College, where she also had served on the staff of "The Owl," the school paper.

She had worked in the accounting department at Creative Mailing Consultants in Capitol Heights before becoming head bookkeeper at Manor Care nursing home in Wheaton earlier this year.

Miss Hayes had been active in community and charitable work, having served as a hostess at benefits sponsored by the Greenbelt Jaycees to raise funds for the Greenbelt Cultural Arts Center. She also recently had completed her third March of Dimes Walkathon in Washington.

Survivors include her parents, Mr. and Mrs. William A. Hayes Sr., of Berwyn Heights; a sister, Patricia Ann Rainey of Lanham; two brothers, William Jr., of Laurel, and Lawrence A., of Berwyn Heights, and a grandmother, Jane Hayes of Northfield, N.J.

The family suggests that expressions of sympathy be in the form of contributions to the March of Dimes.
