Deputy NSW Coroner Harriet Grahame will look into the 2014 disappearance of William Tyrell, and an inquest into the case has been proposed for next year.
The case of missing NSW boy William Tyrrell is to be handed to the coroner and an inquest has been proposed for next year.
On the fourth anniversary of William's disappearance, NSW Police announced that investigators have been speaking with the coroner and an inquest before Deputy NSW Coroner Harriet Grahame has been proposed.
In a statement, NSW Police said investigators in the case "would like to acknowledge the continued strength and courage of William Tyrrell's families today.
"Over the past year, investigators have continued to explore lines of inquiry in an effort to find out what happened to William, including a large-scale forensic search," it said.
The deputy coroner has requested a brief of evidence, the statement said, which would be provided by the end of the year.
The inquest will be "an opportunity to test information and evidence gathered by Strike Force Rosann and further the investigation.
"This is another step in ensuring answers are provided to William's loved ones," the statement said.
William was playing in his grandmother's yard at Kendall on the NSW mid north coast when he vanished on September 12, 2014.
He was three.
Despite a large-scale search, no trace of him has been found.
