I still have a problem with the NW being the lone assailant.
1) It is assumed by many of us that Barry returned from work earlier than his usual time. Was it just a random occurrence, did Barry return home at different times with no regular pattern, or was it planned?
Did Honey want him home early, were they to meet somebody at their home, what was the reason to be home?
2)Was it a coincidence that they were murdered that evening, or was it it all pre-planned?
If Barry came home at his usual time later in the evening, was the NW going to wait outside until Barry arrived, or was the NW waiting inside the house.
3) The TPS probably have a pretty good idea how many people were in the house with the deceased. We assume one was the NW. Was there a number two? I think there had to be, as it would be risky to have one person strangle two people. Yes one person could be all that was needed, but the chance of problems would be much greater.
