You may not know that I was once convinced of his innocence. I confess to still having very rare moments of questioning my belief in his guilt now that I've changed sides. However, what brings me back to reality is the thought of him idling his way through a phone book, at silly o'clock, to look up local police stations after his father had allegedly called him to say that Sheila had gone mad and got hold of a gun. Not satisfied with that, he calls his girlfriend before he speaks to the police.
This is just the worst type of reason to change sides April.
20/20 hindsight is employed here. You can only imagine one universe, that where there are 5 bodies, but everything you describe is before he knew anything happened.
This explains all the oddities. He knows Sheila is a nutbar, but not a killer.
As has often been pointed out at a sane forum like IA, the best strategy for a guilty Bamber is to lie low till normal farm time, turn up, call the cops and say,
Look at this, that crazy sister of mine has finally cracked and killed them all. After all, Taff Jones decided that was what had happened immediately. All the ideas Bamber would add a complex portfolio of moving parts with phone calls and so on is ridiculous.
In fact I will start a thread so we can discuss this. Not right now, but when I have thought it through more thoroughly.
