Mildred Hosler, 50, was fatally shot four times on December 22, 1973, while walking to a downtown San Francisco bus stop. Her death was one of a series of racially motivated attacks in the city between October 1973 and April 1974 known as the Zebra murders.

That group was linked in these reports to at least 15 murders and numerous other violent crimes; one member, Anthony Harris, reportedly cooperated with authorities and provided information that led to arrests.

What details about Mildred’s life, her route that morning, or additional witnesses are still missing that might help anyone who knew her or saw something that day come forward?
