getting back to the roundabout, perhaps they did drive out to Kholo via RG Road. Perhaps NBC did get picked up near home (around Kilkivan somewhere). I personally beileve Allison was wrapped in a blanket, tarp, sheets etc...something to transfer her from the house to the car, and something to protect the car from evidence. (we know that it didnt completely protect the car because a portion of her body (most likely head) appears to have been exposed, and some blood loss has possibly trickled out from the blanket or tarp) this fits in with Rationals point that there is a specific straightline where the luminol was sprayed.
Ok, Im getting there. So, my next point is this, they wouldn't leave blankets, or anything from their own homes that would connect them to the scene where her body was dumped. So they might take it back to Kenmore Village to the bins. Its later in the evening by now obviously.
After a night such as this, I can easily imagine things getting heated between family members. NBC would be wanting to kill GBC himself, for his stupidity and for what he has done and for dragging his family into it. . It stands to reason that after all the deed is done and they have dumped any incriminating evidence into the bins, that they too had an outburst of arguing again, father furious at son (ive heard he is an angry angry man) and this could be what the neighbour reported to police that night near the roundabout.
Ok, tHis is my point: NBC could have lost his cool with GBC and HE stormed off and said, 'bugger off, ill get me own way home, I cant stand even looking at you right now' or he says, ring mum to come pick me up, I cant even look at you right now. (the factime call?)
Just trying to bandy round ideas relating to the roundabout agin and the possible NBC sighting
also, there is Jools who saw possbile arguing by people at a white van at 11.00pm, which could have been GBC and NBC earlier in the night??
