The Unsolved 1970 Murder of Claire Gagnon
On May 24, 1970, the quiet community of Dieppe, New Brunswick was shaken by the disappearance and murder of 16-year-old Claire Gagnon. More than 50 years later, her case remains one of the province’s enduring unsolved mysteries. Below is a breakdown of the key details surrounding the case.

Timeline of Events
May 24, 1970 (2:00–3:00 p.m.): Claire is seen alive for the last time. The exact location of her disappearance remains unknown. May 24, 1970 (5:00 p.m.): Claire fails to return home for her family’s traditional Sunday dinner. Knowing this is completely out of character, her parents immediately realize something is wrong. May 25, 1970 (evening): Approximately 24 hours after she went missing, Claire’s body is discovered in a field just 300 yards (about 900 feet) from her family home.
The Investigation and a False Confession
Following the discovery of Claire’s body, law enforcement officially ruled her death a homicide. Evidence at the scene indicated she had been restrained, but there were few clear clues pointing to a specific suspect. At the time, Dieppe was a small town of just over 4,100 residents, making the brutal crime deeply shocking to the tight-knit community. Over the decades, investigators pursued numerous leads. In 1993, twenty-three years after the murder, a man confessed to the crime and was formally charged. However, alibis and records later confirmed that he had been a resident at a psychiatric hospital at the exact time Claire was killed. Because it was impossible for him to have committed the crime, the charges were dropped and the case remained unsolved.
Current Status
Despite the passage of more than half a century, multiple lead investigators, and major advances in forensic science, the person or persons responsible for Claire Gagnon’s death have never been identified. The case has received relatively little major media coverage, but for Claire’s family, friends, and the community of Dieppe—which has since grown into the fourth-largest city in New Brunswick—the memory of Claire and the search for justice continue.
