Murder of two children by mum's partner preventable, coroner rules

WARNING: Aboriginal and Torres Strait Islander readers are warned the following article contains images of deceased persons.

The deaths of two children murdered by their mother's partner could have been prevented if child protection had intervened, an inquest has found.

Adeline Wilson-Rigney, her six-year-old daughter Amber Rose and five-year-old son Korey Lee Mitchell were found dead on a property at Hillier, north of Adelaide, in May 2016.

In 2017, Ms Wilson-Rigney's partner Steven Peet was jailed for life over the triple murder.

Deputy State Coroner Anthony Schapel released his findings into the death of the two children, saying the Department of Child Protection was aware of concerns about them living with their mother.

However it didn't investigate because of resourcing and staffing pressures in its Elizabeth office.

The Deputy Coroner also said successive governments have failed to implement all of the recommendations of previous inquests into the child protection system.

The children's grandfather, Steven Egberts, said he wants to ensure no other family endures what they have.

"We'd call on the current premier to make the necessary changes and hopefully save some children," he told 9News.

"It's disappointing that it's taken six years to get to this point and probably even more disappointing is how belligerent the departments been in accepting any sort of change."

The Coroner's finding also recommends an internal review of all staff reporting practices.
