An inquiry is underway into a Queensland lab that failed to test thousands of DNA samples. The lab demanded that to progress to DNA profiling, crime scene samples require the equivalent of at least 22 cells, but fewer than 10 cells can often produce a DNA profile. 

The discovery was triggered by the Walkley Award winning journalist Hedley Thomas’ Shandee’s Story true crime podcast. It means there could now be thousands of miscarriages of justice related to the lab. Hedley joins us to talk us through how the crisis emerged and what it means for existing and future cases.
