Sandra Mae Sandy Dykman Smallegan was 19 when she was murdered on February 10, 1974, in Manhattan, Montana. She had been out drinking at the American Legion in Manhattan the night she disappeared and was later identified as one of the victims of David Gail Meirhofer.

Investigators found her remains at an abandoned site north of Manhattan known as the Lockhart Ranch, where bodies had been dismembered and burned. Meirhofer, a Manhattan resident who committed multiple violent crimes in rural Montana between 1967 and 1974, confessed to Sandra’s murder and to killing 7-year-old Susie Jaeger. He was arrested on September 25, 1974, during an FBI manhunt that used psychological profiling to help track him. Shortly after confessing, Meirhofer hanged himself in the Gallatin County Jail and was never tried.

Anyone who knew Sandra, her movements in Manhattan that February, or has information about her last night at the American Legion is asked to come forward.
