Yes lerner, I think you could be right on the money with the mental health issues, taking medication/not taking medication, in a healthy relationship, out on his own again, no self control. Or, maybe he has never been diagnosed by a professional for mental health issues, which, if picked up when he was in his early teens, and I do mean EARLY teens (he was attempting rape at 18/19 that we know of) the murders and rapes might have been prevented. Who knows, not an expert. Ms Anais and Perpendicular can answer these questions better than I, but like you, I have pondered this and mentioned it in a previous post. Like I said in that post, perhaps BRE would never dream of going down the "temporary insanity" avenue, the old, "there's no way I'm a nutter, not ending up in a loony bin with nut cases!" But I think there's something along the lines of "if he hid it, he knows he did it" type of thing with insanity pleas? Will stop now, already way out of my depth!
