Laureen Ann Rahn was 14 when she disappeared from her Manchester, New Hampshire, apartment the night of April 26–27, 1980. Her mother, Judith Rahn, returned about midnight to find all the hallway lights unscrewed and the building in darkness. Judith initially thought Laureen was asleep; the next morning she discovered Laureen was gone. Laureen’s clothes, shoes and purse were left in the apartment and the back door stood open.

Authorities first treated the case as a possible runaway, but Judith and investigators later leaned toward foul play. In October 1980 strange calls appeared on Judith’s phone bill to California, including one to a teen assistance hotline; later silent calls came at odd hours that Judith thought might be from Laureen. A witness once reported seeing a girl resembling Laureen at a Boston bus terminal, but no lead produced answers.

The disappearance remains unsolved. If anyone knew Laureen, saw her that night, or has information about the calls or the reported bus terminal sighting, can you share what you know?
