Anita Beth Fox, 18, a sophomore and a theater arts student at the University of Maryland, died Friday at Prince George's General Hospital from injuries sustained in an automobile accident earlier that day in Laurel.

Prince George's County police said Miss Fox was a passenger in a car involved in a four-vehicle accident Friday afternoon at the intersection of Rte. 1 and Cherry Lane in Laurel. Police said that the driver of the car in which Miss Fox was riding apparently attempted to make a left turn from Cherry Lane onto Rte. 1 in front of a dump truck traveling eastbound on Cherry Lane. The two vehicles collided.

The car in which Miss Fox was riding then struck two other cars stopped at a red light, police said. The investigation into the accident is continuing, police said.

Miss Fox was born in Takoma Park. She attended Whittier Woods Elementary and Thomas Pyle Junior High schools and was a 1980 graduate of Walt Whitman High School. She spent the summer preceding her junior year in high school as an exchange student in the American Field Service program in Cardoba, Argentina, where she became fluent in Spanish.

Before beginning her sophomore year at Maryland, Miss Fox, who planned a career in theater, performed in summer stock at Parkway Playhouse in Burnsville, N.C. She appeared in the chorus of "Oklahoma," and as Mady in "God's Favorite."

Survivors include her parents, Helga Fox of Bethesda, and Lester Fox of Rockville, and a sister, Lenore, of Colorado.
