yes he’s definitely been in there before, that house is a warren but he knew exactly where to go in the time frame he had.do we know that on some or at least one occasion of the other 12 trips that he was not in the house at a "party"??? That house was wide open during these parties and would have been easy to go in...the house was well know for the parties and the time line of those 12 trips was just about the time when the parties were really cranking. Just a thought. I think he had been in there before.
I find it odd there is only one footprint, you’d think they would be all over.
