Shandee Blackburn

A young woman's brutal murder on a quiet suburban street ignites a podcast investigation that exposes a shocking forensic science scandal and leaves a killer still at large.

Shandee Blackburn, a vibrant 23-year-old woman, was brutally stabbed to death in the early hours of Saturday, 9 February 2013, as she walked home from her shift at the Harrup Park Country Club in Mackay, Queensland. Her body was discovered on Boddington Street, just 500 metres from her home, by a passing motorist. She had suffered multiple stab wounds in what police described as a frenzied and unprovoked attack.

Shandee's ex-boyfriend, John Peros, was arrested and charged with her murder in September 2014. However, in a devastating blow to her family, Peros was acquitted at trial in June 2017. The prosecution's case was significantly undermined by failures at the Queensland forensic DNA laboratory, which had failed to properly test critical evidence from the crime scene.

In October 2021, Gold Walkley Award-winning journalist Hedley Thomas launched "Shandee's Story" for The Australian newspaper, a podcast investigation that meticulously re-examined the case. The podcast exposed catastrophic systemic failures at Queensland Health's Forensic and Scientific Services laboratory, revealing that DNA evidence in Shandee's case — and potentially hundreds of others — had been inadequately tested or not tested at all. The revelations sent shockwaves through the Australian justice system.

The podcast's findings led directly to the establishment of a Commission of Inquiry into Forensic DNA Testing in Queensland in December 2021, headed by former judge Walter Sofronoff. The inquiry's damning findings, delivered in December 2022, confirmed widespread failures in DNA testing procedures and led to a comprehensive overhaul of the state's forensic testing system. A follow-up podcast, "Shandee's Legacy," documented the inquiry and its far-reaching consequences.

Despite the renewed public attention and the forensic failures being exposed, Shandee's murder remains officially unsolved. A $250,000 reward remains on offer for information leading to the conviction of her killer. Queensland Police have stated the investigation remains open and active. Shandee's mother, Vicki Blackburn, continues to campaign tirelessly for justice for her daughter, and the case stands as a powerful example of the critical role investigative journalism plays in holding institutions accountable.
