No he hasn't admitted it AS FAR AS WE KNOW. All we have been told is that hes 1) been charged 2) not cooperating.
So as it stands, seemingly no confession and certainly no indication of where her body is.
It is in equal parts fascinating and frustrating.
Could he have confessed to a close friend/family/GF of the murder (but not the body location) who then did the right thing and reported it? He was then arrested, had freaked out and has gone quiet, so police have a witness who will testify to the confession? I’m starting to lean towards this.
An alternative is he’s at some stage confessed to a fantasy that fits this description.
Police are certain SM was murdered, and certain it was by the accused, and I believe they are saying this happened at Mt Clear around 8am. So there MUST be irrefutable evidence in the police’s eyes that (a) SM was murdered and (b) it was the accused. Other than some sort of irrefutable CCTV, dashcam, phone footage, an eye witness or maybe a voice call or recording from SM eg SM getting a quick call away “I’ve been [insert weapon of choice]! It’s a young guy, while Ute, I’m at My Clear… help….”
Most of those scenarios might have led to an even quicker arrest, almost immediately surely.
I’m not even sure CCTV of the accused with the body - say the accused Ute going past a camera and SM is visible in the front or back seat would be enough to be confident SM is deceased, was murdered, and that was all committed by the accused acting alone. It would only be evidence of a kidnapping or if it was clear SM was deceased, tampering with a body.
This case is very perplexing, not following the expected “script”.
