Deborah Lee Tomlinson, known as Debbie, was 16 when she vanished on October 15, 1973 — her birthday — from Creswell, Oregon, though some family members later suggested she may have left from nearby Eugene. She was described at the time as 5 feet 5 inches, 140 pounds, with brown hair and brown eyes and a ring of moles around her neck.

Initial reports said she ran away with another unidentified teenage girl and was classified for decades as an endangered runaway. Family members described strained home life: she lived with her father and stepmother, did not get along with the stepmother, had been caught sneaking out, and was reportedly planning to go live with her biological mother. Over the years unconfirmed leads surfaced — a reported sighting in Santa Rosa, California, with a young man, and a family belief she may have been pregnant when she left — but none produced answers. The family has submitted DNA to national databases and the investigation remains open.

If anyone knew Deborah, her companion that night, or saw her in Oregon or California around October 1973, can you share what you remember?
