A6 disappearances

The A6 disappearances (French: disparues de l'A6, literally the "[female] disappeared of the A6") is the name given to a number of mysterious disappearances or other crimes involving women and girls, occurring in the 1980s, 1990s and 2000s along a 200-kilometer (120-mile) stretch of the A6 motorway around Mâcon, Chalon-sur-Saône and Montceau-les-Mines, France. The area has been informally referred to as the "triangle of fear" (French: triangle de la peur).

The crimes took place between 22 August 1984 and 2 April 2005. Although the police have solved some of the murders, they are unsure of whether the remaining unsolved cases are coincidences or the work of one or more serial killers.
