A 22-year-old woman found dead Sunday morning in her Capitol Hill apartment died of an "incisive wound to the throat," the D.C. medical examiner's office ruled yesterday after an autopsy was performed.

The body of Florence Eyssalenne, who was a paralegal employe for a Northwest law firm, was found in the bedroom of her apartment at 610 Third St. SE. A spokesman for D.C. police said they are continuing their investigation but they had no motive or suspects and they would not comment further.

Harry Gross, resident manager of the apartment building where Eyssalenne lived, said he called police after another tenant saw the woman's body through an open but barred window at the rear of the building. Gross said the only door to the first-floor apartment was locked.

Eyssalenne worked for the last year as a legal assistant, researching and helping to prepare cases for Spiegel and McDiarmid, said Robert McDiarmid, one of the 12 partners in the firm.

"She was perfectly marvelous," McDiarmid said. "She graduated from Harvard in French literature and was working to put herself through graduate school."

"She was one of the brightest kids around," McDiarmid said. "There are 80 people here who loved her and we are all very distraught."

Eyssalenne had lived in the three-story, 12-unit beige apartment building on Capitol Hill since Aug. 29.

Yesterday, Officer Z.D. Hunter IV stood guard by the door sealed with red tape at the end of the hall.

Hunter and Gross, the resident manager, both said that the neighborhood was generally safe and very quiet.
