The WA Ombudsman, Bevan Warner, has released new details of the case, citing media coverage as a reason to make the information public. He said that although individual death investigations are not usually published, the level of public interest justified the report.
Extensive evidence was examined during the review, including police body-worn camera video and more than 1,700 pages of records from key agencies. The review covered 17 emergency calls and six family violence incidents.
Premier Roger Cook said the new material might offer an opportunity for further consideration, noting that if it was not part of the evidence previously considered by the coroner, the Attorney-General could speak with the coroner about it.
The children's grandmother, Dorothy Papertalk, has been calling for an inquest since the deaths, but former Coroner Phil Urquhart denied that request in 2025.
Attorney-General Tony Buti has repeatedly stated he cannot order an inquest, and has published private legal advice to support his position. However, he was challenged in an open letter by former Governor Malcolm McCusker KC and former president of the Children's Court Denis Reynolds. Mr Reynolds argued the Coroners Act 1996 clearly gives the Attorney-General the power to direct the state coroner to conduct an inquest, describing the relevant provision as "very clear and unambiguous, and not qualified at all."
Mr Buti responded that he accepted the advice from the solicitor-general on the matter.
