Jacqueline Lefebvre Missing Person Case

Jacqueline Lefebvre was a 42-year-old woman who disappeared on August 30, 1968, while at her family’s cottage in Mascouche, Quebec. Official Canadian missing-person records identify the cottage as the last place where she was known to have been seen. Born in 1926, Jacqueline was with her family in a setting that ordinarily would have been familiar and personal, but sometime during that day she vanished. There is little publicly available information describing the hours immediately before her disappearance, who last saw her, or what circumstances may have caused her to leave the cottage. What is known is that after Jacqueline disappeared, she was never heard from again, and no verified account has emerged explaining where she went or what happened to her.

At the time she disappeared, Jacqueline was approximately 5 feet 5 inches tall and weighed about 174 pounds, with official records describing her as having a heavy build and a light or fair complexion. She had wavy blonde hair and greenish-blue eyes. Investigators also documented several physical characteristics that could help distinguish her from other people, including braces on her teeth, a vertical scar on her abdomen, and a scar associated with a hysterectomy. She was reportedly wearing a gold wedding band. These details became particularly important as the years passed because they provided investigators with identifying information that could potentially be compared with unidentified persons or remains discovered elsewhere.

Despite the passage of decades, very little about the circumstances surrounding Jacqueline’s disappearance has entered the public record. There are no publicly documented reports describing a confirmed destination she intended to visit, a vehicle associated with her disappearance, a note explaining her departure, or a verified sighting after she was last seen at the Mascouche cottage. The available records similarly do not identify a suspect or publicly establish that a crime occurred. Her disappearance has therefore remained defined by a striking absence of answers: a woman was present at her family cottage, disappeared, and was never reliably seen or heard from afterward. Canadian missing-person records continue to list Jacqueline as missing, and a Quebec National Assembly document reviewing missing adults also identified her as a woman who disappeared in Mascouche on August 30, 1968 and remained recorded in the national missing-person system.

The investigation is associated with the Mascouche Public Security Service under reference number MSC-180410-011. Authorities continue to request information from anyone who may know something about Jacqueline’s disappearance, and information can also be provided through Crime Stoppers or the National Centre for Missing Persons and Unidentified Remains. Even information that may have seemed insignificant at the time could potentially matter in a case that has remained unresolved for so many years. More than half a century after Jacqueline Lefebvre disappeared from her family cottage in Mascouche, the essential facts remain painfully limited: she was 42 years old when she was last seen on August 30, 1968, she subsequently vanished without a confirmed trace, and official records continue to preserve her case in the hope that someone may eventually provide the information needed to explain what happened to her and bring long-awaited answers to those who have wondered about her fate.
