Queensland’s government-run forensics lab has been using a testing threshold that is preventing it from detecting DNA in many samples, says Dr Kirsty Wright, with potentially catastrophic consequences for victims of violent crime. A t-shirt described as 'blood-soaked' is found at a Mackay business near the murder scene – but the lab reports “No DNA detected”. A truck driver who is sure he saw Shandee’s handbag at a Mackay rubbish dump just days after the murder says his information wasn't followed up by detectives for two months. In 2019 the inquest examines new persons of interest.
