It mentions the police questioning in the news item and it's said the mum was annoyed he'd been questioned, it could've been as she was terrified he'd slip up and it's a miracle he didn't I guess, but like Vanessa said if he was traumatised he might have shut it out?
I'll have a look at the tapes tomorrow, it's interesting to hear the guy say that the lack of social norms may be a result of not being socialised following the death of his sister, however I'd have said most kids have the ability to read and react to social cues well before the age of 9, so you would've thought that could be an indication he had communication problems before then?...
