You find it odd that a burglar might have stolen a car so when he made his escape and the car was identified it couldn't be traced to him? I don't find it odd. I find it odd that the police don't seem to know who is actually living in the house.
Burglars bring utility vans to housebreakings, not brand-new BMW's. If he can go out and steal BMW's, what's he doing robbing houses?
I think the whole thing is fishy. I don't think he was a common burglar.
