Ann Marie Burr was eight years old when she vanished from her home in Tacoma, Washington, on the night of August 31, 1961. All four children had been put to bed at about 8:00 p.m.; sometime during the night Ann woke her parents because her three-year-old sister with a broken arm was crying. The parents sent the children back to bed. At 5:30 a.m. Ann’s mother discovered she was missing.

The house showed signs of an intruder: the front door, which had been locked and chained, was open, and a living-room window that had been slightly ajar was now wide open with a garden bench moved beneath it. Searchers found a faint footprint outside the window consistent with a Keds sneaker, size six or seven, and a piece of red thread caught in the window jam. Despite those clues, the bedroom and nearby table of figurines showed no sign of a struggle.

The disappearance prompted a massive search involving soldiers from Fort Lewis, the National Guard and police, and divers combed Commencement Bay, but no trace of Ann Marie was found.

Did anyone in the Tacoma area at the time remember unusual visitors or activity near the Burr home that night?
