Anne Louise Lenning was 21 when she disappeared from Calgary, Alberta, in the autumn of 1992. Reports differ on her last confirmed sighting, with some accounts saying October 1, 1992, and others placing her last known whereabouts in December 1992. She is described as five feet six inches, medium build, blonde hair, green eyes, with a small tattoo on her left ankle.

Very few concrete details about her disappearance have ever been publicized. The circumstances of the day she went missing, who she might have been with, and the precise Calgary location of her last sighting have not been widely reported. The Calgary Police Service has kept her file open.

If anyone in Calgary in late 1992 remembers Anne, her routines, places she frequented, or any detail about her last known movements, please come forward with information.
