In September of 1952, the quiet Brisbane suburb of Grange was changed forever by the brutal murder of 22-year-old Betty Shanks.

A crime that remains one of Australia's oldest unsolved mysteries, Betty was walking home from a night class when she was savagely attacked just metres from the front gate to her home.

In this episode of Exhuming the Truth, we jump deep into the evidence, the forensics, and the speculation that follows.

Was Betty's killer a soldier returning from war?

A police officer abusing his power?

Or a stranger driven by opportunity and rage?

Through forensic reasoning, we revisit crime scene clues and talk about new interpretations of what happened to Betty Shanks.

Join us on this episode of Queensland's oldest, coldest case.
