I’ll just say In My Opinion, as I can’t find links, but it’s been my understanding that he’s been refusing to talk, even when he handed himself in.
That makes me think he’s gone in to Police Station ( Uncle drove him I think ) and said to the effect ‘ I heard you’re looking for me ‘ … and after a process of asking & putting things to him, he was charged with murder, meaning at that stage they must’ve had evidence linking him ( gun, fingerprints, DNA, clothes fibre, hairs etc ) but he still refused to talk.
I heard on a bulletin somewhere, either Monday night or early yesterday morning, that a gun police interviewer was heading to the jail that day to talk to BL & remind him of the ‘no body no parole’ rule.
I may be wrong, but I think it would be necessary for the accused to have a lawyer present - so if BL didn’t have anyone, I suspect police will have arranged someone from Legal Aid to be present.
I imagined the police receiving advice that the lawyer was at Silverwater jail with BL, so gun Detective Glenn ? and female OIC of the case, head off to interview BL. In the end, he told them as much as they needed to locate the boys bodies - but I doubt he was happily forthcoming, as he still needed to maintain his arrogant position of power.
