A friend of Susan Davoudlarian, the 40-year-old woman found strangled in her car at Dulles International Airport 22 months ago, testified in court yesterday that Davoudlarian spoke of herself as "a nymphomaniac" who was unhappy in her marriage and found her husband repulsive.

The friend, Alice Marion, testified for the plaintiffs in Fairfax County Circuit Court at the trial of a $10 million civil lawsuit brought by Davoudlarian's estate, which alleges that her husband, gynecologist David K. Davoudlarian, killed her.

No one has been charged in Davoudlarian's death, and Dr. Davoudlarian, 49, has denied in a sworn deposition having any knowledge of the killing.

Marion, who said she once was a patient of Dr. Davoudlarian's, testified that Davoudlarian told her she had two lovers during the last three years of her life.

"She told me she was very unhappily married . . . ," Marion said. "She said she was physically repelled" by her husband, and that "she was a free spirit and he was a regimentarian."

Marion testified that one of Davoudlarian's lovers was an old sweetheart and another was a stockbroker.

"We called him 'the stockbroker,' " Marion said. "She said he made himself available to her when she needed sex . . . . "

Under cross-examination, Marion testified that Susan Davoudlarian once told her "she had spent all day the previous day in bed with someone, and she said, 'You know, I really think I'm a nymphomaniac."

In opening arguments to the jury earlier this week, one of Dr. Davoudlarian's attorneys argued that Susan Davoudlarian was "deceitful" and "a promiscuous woman" who, because she had affairs, "had entered into a life style that was destined to bring her into harm's way."

Also yesterday, Robert Potterfield, a funeral director, testified it took Dr. Davoudlarian "18 minutes" to make the funeral arrangements for his wife and that Dr. Davoudlarian ordered the cremated remains "disposed of."

Asked why he remembered the exact time it took to make arrangements 22 months ago, Potterfield replied, "It was very unusual to complete the business in that sort of time frame."

The funeral arrangements were made without the help of Davoudlarian's daughters or parents, and testimony about them provided a starkly emotional moment in the proceedings.

Susan S. Rooney, 20, the victim's eldest daughter, answered a question by saying: "What remains? They were disposed of. My mother was thrown away."

Susan Rooney and her sister, Claire E. Rooney, 19, have filed a second civil lawsuit against their stepfather, which also alleges that he killed their mother.
