Gregory Clark Kovin, 19, a freshman at American University and a lifelong resident of the Washington area, died Friday at Sibley Memorial Hospital as a result of injuries he suffered in an automobile accident earlier that day.

D.C. Police and Mr. Kovin was a passenger in a car driven by his brother, Christopher Kovin, that jumped a curb and struck a tree in in the 4500 block of Massachusetts Avenue N.W.

A second passenger, John F. Kovin, the father of Gregory and Christopher, was taken with Christopher to Georgetown University, where they were treated for their injuries and released on Sunday, hospital officials said.

A third passenger, John Percesepe, 40, of New City, N.Y. was taken to the Washington Hospital Center, where he died of his injuries early Saturday, police said.

Gregory Kovin was born in Takoma Park and was a resident of Bethesda. He was a graduate of the Eastmoor Academy in Nantucket, Mass.

In addition to his brother and father, both of Bethesda, Mr. Kovin's survivors include his mother Mrs. John F. Kovin, also of Bethesda, and his grandparents, Mr. and Mrs. James Hagle of Dublin, Ohio, and Mr. and Mrs. Fred Kovin of Saginaw, Mich.

The family suggests that expressions of sympathy be in the form of contributions to the Gregory Kovin Memorial Fund, Eastmoor Academy of Nantucket, c/o Suite 1200, 815 Conn. Ave. N.W. Washington, DC, 20006.
