The death of Jeanette Bishop and Gabriella Guerin occurred sometime between November 29, 1980, when the two women were last seen in the Italian town of Sarnano, and January 27, 1982, when their remains were found near Lago di Fiastra in the Sibillini Mountains.^[1] How Bishop and Guerin met their deaths, what they were doing between their disappearance and the likely date of their deaths a month later, or even why the two ventured up into the mountains in snowy weather, is unknown. Initially ruled deaths caused by hypothermia, by September 1989, the investigating prosecutor concluded it was a double murder by unknown perpetrators, using unknown means. Over the course of investigations, enquiries expanded to other countries, mostly to the European Union, but also to Brazil and the United Kingdom and encompassed possible connections to art theft, robbery and alleged blackmail plots.^[2]
