In 1975, Shirley Finn, a brothel owner in Perth, Australia, was found executed in her car after leaving the night before to meet with a man who was supposed to help her out of a tax situation.

There is a long-standing belief that her death had a lot to do with the corruption in the West Australian Police Force at the time. Shirley’s family, reporters, and investigators believe they know why the mother of three was murdered that night. However, despite countless pieces of evidence and a recent inquiry into her death, her case remains unsolved.
