Bundaberg police confirm human remains found in search for missing Queensland teen Pheobe Bishop
Snipped by me:-
“He said cadaver dogs were used in the search and the remains were discovered in bushland.” (Referring to “he” as Insp Mansfield.)
“Police "believe the remains were not buried", Inspector Mansfield said.”
"We happened upon a track that did look similar to the original track but in a different location, which would seem suitable if we were mirroring an original location of what we believe Pheobe was at," Inspector Mansfield says.”
"It was then that the capability was then able to be deployed onto that and the remains were found".
“Inspector Mansfield says police have not determined a cause of death for the human remains they have found.”
"We will conduct our examinations with a view of course of trying to determine a cause of death, whether that is able to be achieved is yet to be determined," he says.”
Police confirm human remains found in search for missing teen Pheobe Bishop
Police confirm they have discovered human remains near the Good Night National Park near Gin Gin.

From reading this, I don’t think that the alleged murderers have revealed where they hid Pheobe. Inspector Mansfield is saying that they “happened upon a track”…. not that the people they have charged have revealed the location.
