A shocking report has uncovered major DNA processing failures impacting victims of crime, courts and police.

The report into Forensic Science Queensland (FSQ) tabled in parliament on Monday found unprocessed rape kits, contamination, unreliable results, and results returned over a year late.

Former NSW Police commissioner Mick Fuller will spearhead a revamp after contamination issues, testing delays and unreliable results since early-2023 were identified in the embattled lab’s latest probe.

Attorney-General and Minister for Justice Deb Frecklington said the findings by review forensic biologist Dr Kirsty Wright are “chilling”.

Rape kit testing backlogs spanning years could be leaving child rape victims at risk of repeated assault.

“Of significant concern is the ongoing risk to child victims and victims with impairment involved in rape or sexual assault allegations,” the review said.

“Failure to test rape kits for these priority unresolved cases is likely placing these vulnerable victims at high risk of further rapes or sexual assaults.”

“This report shows what has occurred is nothing short of a betrayal of victims, but we are determined to rebuild confidence and restore integrity in the justice system,” the Crisafulli Government said in a statement.

The inquiry also found crime scene samples were knowingly being processed in a “dirty lab” on unclean surfaces for at least a year or more.

“They knew this ... they were repeatedly finding that the examination surfaces were dirty,” she told reporters.

Forensic Science Queensland director Linzi Wilson-Wilde resigned in July, a month after being suspended over “contamination issues” at the lab.

DNA evidence for major crime cases over the past two-and-a-half years are set to be re-examined following the “confronting” report.

The median time for the lab to process material for major-crime cases was about 420 days, Wright said.

“Victims are waiting over a year for the rape kits to be tested,” she said.

“In other jurisdictions, that’s taking five to 10 days. So you can see the chasm in the service that we need to rebuild.”

Queensland Magistrates Court cases relying on DNA evidence were being delayed by up to three years.

“That’s just simply unacceptable,” Wright said.

Frecklington felt for major crime victims “waiting for the justice system” because of the lab’s failings, saying some may be left in danger.

“Women and children ... may be in harm’s way because they are still waiting on the justice system to catch up,” she told reporters on Monday.

"One of the greatest failures of a justice system in the world"

The report called the flawed DNA testing and mismanagement of the forensic biology laboratory “one of the greatest failures of a justice system in the world”.

“Queensland’s criminal justice system had been compromised, many thousands of victims had been denied justice, and the communities’ trust in forensic DNA services lost,” it said.

More than 13,000 samples — up to 12 months’ worth of crime scene submissions — are still to be re-tested following the previous two inquiries in as many years.

Forensic Science Queensland was established in May 2023 after the two inquiries exposed major lab failings.

They included a “fundamentally flawed” automated testing method that may have led to offenders potentially escaping conviction for nine years from 2007.

But Wright said post-inquiry changes to the DNA testing method had been done incorrectly, ensuring samples from May 2023 would have to be re-tested.

“We’ve found systemic contamination. We’ve found shortcuts are being taken,” she said.

“We’ve found that the accreditation standards aren’t being adhered to ... test methods are being used that haven’t been properly tested.

“So we need to go back and examine that further to see how many cases in the last two-and-a-half years might have been compromised.”

Fuller will head an expert team to drive the report’s 26 recommendations that provided a “comprehensive blueprint” for change.

Wright had previously spoken out about the lab, triggering the two inquiries.

She was appointed to oversee the latest lab review with renowned FBI expert Bruce Budowle by the Liberal National government after they claimed the 2024 election.

Queensland Premier David Crisafulli on Monday blamed the lab debacle on the former Labor government.

Asked if those responsible would be investigated, Crisafulli said there would be an opportunity for people to explain their part “including people still in the parliament”.

“If there are people who need to be held accountable, they will be held accountable,” he said.
