Humiliated. Belittled. Embarrassed. Toxic behaviour by the lab's managers leads to an epic spray from a reporting scientist in this week's episode. Ingrid Moeller used her time in the witness box to unleash on less-than-stellar management of the state-run lab at the centre of the Commission of Inquiry.

Plus, we hear from her colleagues, who tried time and again to raise the alarm about toxic culture and controversial lab practices.

We also grapple with the magnitude of the lab's extraordinary backflips on statements provided to Queensland Police, with potentially thousands of cases thrown into doubt as a result.

Join The Australian’s National Chief Correspondent, Hedley Thomas, and his colleagues Claire Harvey, David Murray, and Matthew Condon, as they discuss the third week of the Sofronoff inquiry.
