Four weeks in, one question lingers in the Walter Sofronoff-led Commission of Inquiry into Queensland’s state-run forensics lab: who knew what and when?

In this week’s episode, Hedley Thomas, Claire Harvey, Matthew Condon, and David Murray further unpack the toxic treatment of scientists who attempted to raise the alarm about inadequate DNA profiling processes and questionable management practices. We look closely at the behaviour of figures who’ve loomed large but have yet to enter the witness box: Lara Keller, Cathie Allen, and Justin Howes. 

Matt Condon also delves into the fascinating history of the facility and the unique way death is dealt with in Queensland.
