Robin Nadine Benedict was 21 when she disappeared on March 5, 1983. She had been working as a high-priced prostitute in Boston’s adult entertainment district and had a relationship with William Douglas, an anatomy professor at Tufts University. Douglas bought Benedict expensive gifts, including a car and a house, and embezzled more than $67,000 from the university to fund his payments to her.

Benedict tried to end the relationship by early 1983 and even called Douglas’s wife on March 2 asking her to intervene. On March 5 Douglas phoned Benedict twelve times; she was last seen driving the car he had given her, reportedly headed to his home. The next day a teenager found a blood-stained work shirt, a woman’s corduroy jacket later identified as Benedict’s, and a hammer in a trash can along an interstate.

Investigators found Benedict’s pocketbook, credit cards, and phone book in Douglas’s closet fifteen days after her disappearance, and her blood-stained car turned up near New York’s Penn Station in July. Douglas pleaded guilty to manslaughter in April 1984, saying he bludgeoned Benedict to death with a hammer and disposed of her body in a dumpster in Rhode Island; her remains have not been recovered. Does anyone have information about Benedict’s movements in Boston in early March 1983 or about sightings of her car after March 5?
