The man formerly charged and acquitted with the murder of North Queensland woman Shandee Blackburn is taking legal action against her sister and others involved in a true crime podcast about the death.
Shandee Blackburn died on a Mackay street after being stabbed more than 20 times in the early hours of February 9, 2013.
Her boyfriend John Peros was accused of killing her, but a jury acquitted him of the charge following a 12-day trial in 2017.
In 2020, a coroner found Mr Peros was responsible for Shandee's death.
Mr Peros came under the spotlight again through journalist Hedley Thomas' 2021 podcast, Shandee's Story.
Podcast analyses death
The podcast featured an analysis of the investigation into Shandee's death that highlighted the state's alleged forensic failings during the case.
The coroner has since reopened the inquiry into her death, with others expected to follow as public hearings continue to probe the extent of a state-run forensic laboratory's mistakes.
A police task force has also been created to re-examine thousands of major crime cases after the lab incorrectly handled DNA evidence.
But on August 11, Mr Peros, who lives in Western Australia, launched legal proceedings in the Supreme Court of Perth against the podcast creators and those affiliated with it.
The civil action has been launched against Nationwide News, Hedley Thomas, Harvey Norman (which sponsored the podcast) and Shandee's sister Shannah Blackburn, who spoke on the podcast.
No appearances have been made.
