Annemaria Frances Warren, 21, a senior in the College of Arts and Sciences at Georgetown University who was active as a nursing home volunteer, died Jan. 18 at Arlington Hospital of injuries sustained in a two-car automobile accident in Arlington.

An Arlington police spokesman said Miss Warren was alone in her automobile, traveling south on Little Falls Road in Arlington, when her vehicle was struck by another car, which was traveling west on Old Dominion Drive. Miss Warren, who suffered internal injuries, was pronounced dead after being taken to Arlington Hospital.

According to the spokesman, there were no other injuries and there were no charges filed in the accident, which is still under investigation.

Miss Warren, a native of Milton, Mass., had attended Georgetown University for the past four years. Originally a student in the School of Nursing, she recently transferred to the College of Arts and Sciences and was majoring in psychology.

Active in the Georgetown student community, she had served as a resident assistant at Darnall Hall in 1978 and 1979.

She divided much of her leisure time between her hobby of skiing and serving as a volunteer at nursing homes in Massachusetts.

Survivors include her parents, Bruce and Joanne Warren, a sister, Kimberly, a brother, Garrett, and a grandmother, Mary Siebert, all of Milton, Mass.

The family suggests that expressions of sympathy be in the form of contributions in Miss Warren's name to Georgetown University.
