Helen Edith Booth was 17 or 18 when she disappeared from Toronto, Ontario, in the winter of 1969. The last confirmed sighting was the night of Saturday, December 13, when she was out with her boyfriend. Around 11:30 p.m. he understood she planned to go home with a friend; she was never seen again after that.

Details about her final movements are scarce. The investigation eventually went cold and little public information about witnesses or physical evidence has been reported. Her case has been circulated through missing persons networks over the years but no tangible leads have been disclosed.

Does anyone who lived in Toronto in December 1969 remember Helen, the friend she planned to go home with, or any other details that could help reopen inquiries into her disappearance?
