Archie Tevanian was reporting the disappearance of his 65-year-old wife, Margaret, whom he had discovered was not in the house when he looked for her at 7 a.m. that morning.
Margaret Tevanian was described as weighing 110 pounds, five feet three inches tall, with brown eyes, and shoulder-length gray hair.
When she was last seen she had been wearing a white housecoat, pajamas, a blue kerchief, and brown shoes.
According to family reports, she was suffering from mental illness and hadn’t left the house for several months. Margaret Tevanian had graduated from nursing school as a young woman. She lived in the family home at 50 Cedar Street with her husband and her son Robert, who was 31 at the time. A daughter Laura was married and not living at that address, but another daughter Robin, who had a disability, lived next door with Archie’s brother Leon, his wife Mary, and Mary’s sister. Cedar Street is in Bayside, in the center of Portland’s busy peninsula.
Mary Tevanian had made dinner the night before, at 44 Cedar Street, where Archie had eaten with his relatives, before taking food home for Margaret. Archie’s primary responsibility was taking care of his wife at that time, and Archie and Margaret had been married for over 30 years.
Margaret Tevanian had wandered away from her house on several occasions, when she had been found in Deering Oaks, the area around the post office on Forest Avenue, and Franklin Towers.
As of 5:17 p.m. on that Saint Patrick’s Day in 1996, Margaret Tevanian was officially listed as missing with the National Crime Information Center (NCIC). The NCIC is referred to as "the lifeline of law enforcement." It is an electronic clearinghouse of crime data that all agencies nationwide are able to use at all times.
The next day the case was assigned to a detective. A meeting with the family was held and the preliminary investigation began.
Police did a lot of interviews; they knocked on doors and spoke with neighbors, but did not determine any significant leads as to the whereabouts of Mrs. Tevanian.
Archie Tevanian died June 30, 1996, just three months after his wife’s mysterious disappearance. He had difficulty breathing and collapsed while at home with his son, suffering possible cardiac arrest. After being transported to a hospital, he didn’t recover. He was 72 at the time.
In July 2002, Detective Paul Murphy was assigned the case and has had it ever since that point. Murphy stated that the police department got Mrs. Tevanian’s dental records and that the Medical Examiner’s Office in Augusta has duplicates of all physical evidence.
Police received consent to search the Cedar Street home and nothing out of the ordinary was discovered.
In March 2003 Murphy said a group of detectives began working on some old cases. Each group had seven or eight detectives with one of them serving as a primary. There was also an evidence technician assigned to each group. "We were able to go back and speak with previous investigators," said Murphy.
In May 2003 Detective Murphy asked Robert Tevanian if he would give permission for dogs to be brought to the home, which he allowed. Murphy said Robert Tevanian was "very receptive" to the dogs and he was disturbed that his father wasn’t able to live to see closure to the case. Murphy said "It was one more angle, one more way to possibly develop a lead. It didn’t give us anything else to work on." He stated that he said to Robert Tevanian: "We are using whatever methods are available to us—so many years later—to do whatever we can to solve your mother’s disappearance."
Two dogs from the Medical Examiner’s Office were used, human remains detection dogs, sometimes referred to as "cadaver dogs."
Murphy said "Robert Tevanian was always friendly, cooperative, and appreciative." He continued, "The lack of investigative leads makes it difficult to find a direction."
Commander Vern Malloch was the lieutenant in charge of the detective division in 1996 and he remembers the case because of its unusual aspects. He stated "There was no sighting of her ever. The question we’ve struggled with is whether or not there was foul play involved, and we’ve never been able to say definitively one way or the other."
Malloch said the presumption of the police department is that she’s dead. He said "The likelihood of her being alive is pretty remote, due to her age, and the fact she’s had no contact with family or friends."
On April 23, 2004, Judge William Childs signed an order declaring Margaret Tevanian deceased.
However, it is still an active missing person case to the Portland Police Department, which has spent so many hours over the years, working to try to solve this disappearance.
