Just been watching the interviews with Brendan. They are horrible to watch, so many words kept being put in his mouth and he said he didn't do anything and they kept telling him he's wrong tell the truth. No parents or lawyers present?! Surely that's not right. I agree, he doesn't have the mental capacity of a 16 year old, he didn't understand what he originally confessed too, even asking if he could leave in an hour, he doesn't know the word inconsistent. At no point did he say Steven avert was "hot and sweaty"
It's all highly suspect but at the same time this is a documentary to show his innocence.
The key is a question mark. Found by the same police men from the original case who weren't allowed to search?!
