Jack the Stripper: The Signature Scotland Yard Never Solved
-
Narrated by:

Written by:
September 1996. A man with sixteen documented sexual assault convictions walks free from a Victorian prison. Psychiatric records flag him as high-risk. No one stops him. Thirteen months later, a woman is found dead with injuries Australian forensic science had never documented before.
In this investigation, we examine how Peter Dupas moved through decades of institutional cycles-arrested, convicted, released, reoffended-each time the system processing him without breaking the pattern. We reconstruct the three murders that finally caught him, the forensic signatures that linked them, and the central question: why did a system with complete knowledge of his escalating violence repeatedly set him free?
Victim: Nicole Paterson, Margaret Josephine Mack, Mersina Halvagis
Location: Melbourne, Victoria, Australia
Date: 1997-1999
Status: Convicted; three life sentences
- A man released in September 1996 with sixteen prior sexual assault convictions and documented psychiatric warnings against release
- A forensic signature so specific-mutilation of breasts and surgical placement-that it appeared in case files as unprecedented in Victorian records
- Investigators discovered he had called Nicole Paterson's phone fifteen times in forty days while denying ever knowing her
- His grandfather's grave was 128 meters from Mersina Halvagis's body, and he rented a hotel directly across from the cemetery where she was found
