Madlyn Crouse, 74, was found dead in her Main Street apartment in Nashua, New Hampshire, during the overnight hours of February 27–28, 1976. Investigators determined she had been strangled, and detectives treated the death as a homicide from the outset. Contemporaneous death notices list her as dying in Nashua that late-winter weekend, with services held at St. Patrick’s Church days later.

Officials consistently reaffirmed the February 27 or early February 28 timeline, and the case has remained on the state’s list of unsolved killings. A major setback came when evidence from the case was destroyed sometime in the late 1980s, a loss later documented by police and the attorney general’s office. Authorities said potential suspects were identified after the killing and that investigators later believed they knew who was responsible, but the remaining record was not strong enough to bring charges. No arrests have ever been made; the homicide remains unsolved and the investigation is open and seeking information.

If anyone knew Madlyn Crouse or has information about her death or that late-February 1976 timeframe in Nashua, please come forward.
