Where is it said that when the cleaning person and the gardening person arrived on the Friday morning, the doors were locked? Even if those people had taken their keys and put them into the lock and turned them, would they know for sure whether they had been locked or unlocked? ie sometimes when I arrive at my house, I'll stick my key in and turn it to unlock it, but it won't have been locked in the first place.. IF I am paying attention, I will notice this,... but if not, then I just WON'T notice. I don't think police can have any kind of assurance as to whether all of the doors in the house were locked after this crime took place.
The jackets/coats may be a red herring. On the one hand, the PI team have said the couple were strangled to death and THEN hung (which obviously makes sense), while on the other hand, they mention the coats being down from their shoulders, presumably limiting their movement. In my own mind, I am thinking that the wrist bindings were used for a time, for convenience/control, etc., and then removed later, after death at some point. If Barry's legs were staged like most recently indicated, and his glasses in place on his face - but yet he was either murdered or self hung to death, these things would be unlikely (impossible?) to find that way. If the wrist bindings were removed after death, after hanging up for display, then wouldn't it be normal for unbuttoned boats to fall off the shoulders of a body that has no muscletone whatsoever to keep it in place, or to sit upright, etc.? ie gravity? I think it entirely depends on exactly the coats worn, their fit, whether they were winter coats or suit jackets, whether neat fitting or bulky or loose, etc. In at least one article, it stated that 'winter coats and boots' were worn, but in others, it has not specified. Unfortunately we only have a small piece of the total picture, from which we can't insist on correctly knowing, one way or the other.
