Shirley Ann McBride, 15 and known as Tippy, disappeared from Concord, New Hampshire, on July 13, 1984. She was last seen leaving her half-sister’s apartment on Union Street about 9:30 p.m., reportedly headed to collect money owed for babysitting and then to meet her 21-year-old boyfriend at his workplace, Concord Litho, near the Merrimack River. She took no extra clothing or money and was never seen again.

Family members said Shirley had struggled after a recent move from Manchester to Pittsfield, with school attendance problems and marijuana use, but they maintain she did not leave voluntarily and suspected foul play. A notable lead involved a man named Walter Davis, who was seen trying to burn damp clothing days after her disappearance; denim bib overalls in that batch were later identified by Shirley’s family as hers. Davis refused a lie detector test and died in 2003. Shirley was legally declared dead in 1996, but there has been no verified trace of her since July 1984.
