More Forensic Laboratory Errors in Australia

In Western Australia, a Corruption and Crime Commission investigation is underway after it has been revealed that a mistake in labelling DNA samples in a laboratory led to the wrongful conviction of a man in 2004. There are lots of aspects to this story that beggar belief. Here are some that we know about already:

  • The original mix-up at the laboratory: DNA found at the scene of a burglary was incorrectly identified as belonging to the innocent man. The DNA actually belonged to a man with the same name and a laboratory worker assigned the DNA test results to the wrong person.
  • The laboratory informed the police of the mix-up after it’s discovery in April 2016 when the real offender was arrested over a separate matter. The police then took a further YEAR to act on this information.
  • The victim initially protested his innocence to police but agreed to plead guilty on the advice of his lawyer who apparently told him that no one was likely to believe him and that he risked a prison sentence if he went to trial.

This laboratory is again under investigation – hot on the heels of another inquiry launched last month after it emerged a forensic biologist for PathWest, Laurance Webb, was sacked because he breached testing protocols four times between 2008 and 2014, including failing to conduct quality control testing and have work peer reviewed (see here….) . There is also an urgent question over why the police took a year to act on the information. One must surely also question the original legal advice to plead guilty – though that is not being mentioned in any of the media reports below:
