The 21 year old guy said he doesn't remember raping, robbing, or murdering her because he "blacked out" but he says he regrets it?
You believe that? That means he doesn't have to supply a single detail of how the rape and murder even happened. And the DNA evidence? Trivial to link to somebody in a corrupt system. If he's going to confess he needs to provide details, like if she was sodomized, where he hit her, etc. Plus what drugs was he on? Either he could still test positive or they can hair test him.
