Characteristics: Doreen had brown hair with green eyes, a chicken pock mark on the front of one calf, capped front tooth and noticeable Massachusetts accent.
Details: Doreen Marfeo was the wife of Stephen Marfeo. She was a tidy, punctual person who visited her elderly mother often. In October of 1989, she abruptly quit her job and, according to Stephen, began behaving erratically. On March 29, 1990, she didn't make her usual call to her mother, and when Stephen came home, he waited two days to declare her missing, doing so only after her mother threatened him into it. When asked about her, he claimed that she had taken only a week's worth of clothes in a suitcase and had only $600 with her. She left behind her curlers, toothbrush, pet cats, and 1984 Ford Tempo. The authorities considered Stephen as the most likely suspect in her disappearance and believed he had murdered her, based on the fact he had hired private investigators to follow her for eleven months and his delay in reporting her missing.
Three months after she vanished, two anonymous letters were sent to police. One attacked her character, accusing her of having affairs with several men that she worked with, while the other described how Stephen gruesomely murdered her and dumped her body into a pond. Police could find no evidence of an affair with any co-workers. However, ten years earlier, Doreen apparently told her sister that she was having an affair and contemplated leaving Stephen. Authorities however found no evidence to suggest that she had done this again. Doreen's disappearance remains unsolved.
Suspects: The police long suspected Stephen Marfeo of killing Doreen. During the police investigation, he changed his story about the last time he saw her several times. Authorities felt it was suspicious that he had hired two separate private investigators to follow her around prior to her disappearance, but when she actually vanished, he seemed unconcerned with locating her. A psycho-linguistics expert examined the anonymous letters sent to the police. The expert believed that the letter writer was close to Doreen and knew her well. He felt that the letters were written to throw off the investigation. Overall, he concluded that Stephen most likely wrote the letters, and that he was most likely responsible for his wife's disappearance. A type style comparison later confirmed that the first letter was written on Stephen's mother's typewriter.
Extra Notes: This case originally ran on the November 17, 1993 episode.
Results: Unresolved. Although no trace of Doreen has ever been found, in 1999, Stephen Marfeo shot and killed his ex-girlfriend, Laura Vincent, and seriously wounded her new boyfriend, Sal Puleo, before driving to a secluded reservoir and taking his own life. His suicide letter mentioned that he was alive "nine years too long" and that he had "felt guilty" for Doreen's disappearance, but he did not claim direct responsibility. However, these actions seem to imply that he had something to do with it. Many detectives are certain that Stephen killed his wife, but believe the case cannot be closed until Doreen's remains are found.
