Joan Marie Stewart, a 44-year-old biology professor at San Francisco City College, was found murdered on January 6, 1982, in the woodlands near Montclair, California. She had been raped, strangled, and stabbed multiple times. Investigators recovered a half-eaten piece of Canadian bacon at the scene; witnesses reported a suspicious vehicle in the area whose license plate matched a local man with a history of violent crimes, Charles Jackson Jr.

Jackson’s mother reportedly gave him Canadian bacon for breakfast, a detail investigators said linked him to the evidence. He was arrested on January 8, 1982, and charged with Stewart’s murder. Jackson was convicted in 1983 and sentenced to life imprisonment; a retrial in 1986 again produced a life sentence.

Does anyone have information about Joan Stewart’s life or movements in the days before January 6, 1982?
