This is the great mystery. Why was there no forensic evidence inside the home? The ONLY thing, to my knowledge, we have ever been advised is that it is an established fact that Stacy is known to have exited out the front OR her DNA was found on the front porch. (the exact circumstances are not known). That suggests to me that PERHAPS the women were abducted outside the home. And then, this goes back to the disputed George's sighting. It does not, however, explain the stacked purses. I don't have a good explanation for that dichotomy. They obviously didn't stack themselves, although I suppose it is possible that the girls stayed outside and they gave their purses to Sherrill who took all three purses inside and stacked them. That might explain that problem.
If the George's meeting took place, AND upon returning and the girls stayed outside to chit-chat with the men claimed to be there, and Sherrill came outside to find out what was going on later on, then that might explain why no DNA was there. As you say, Rader left DNA but they didn't have a sample of his DNA to match until shortly before he was apprehended. We don't have any known DNA or fingerprints or other forensics EXCEPT from the known people who were inside the house. This is why I have insisted that they be eliminated FIRST before we go off on some other wild goose chase. Applying your KISS principle, this seems to me the first order of business.
And not to sound like a broken record, I do not and will not, until shown otherwise, that this case was properly and thoroughly investigated. That is my opinion only, but I believe it is well based.
And until proven otherwise, I will likewise continue to believe that Robert Craig Cox, is the lone perpetrator who abducted the women. He has no alibi and he has no incentive to confess to the crime so he sits mute in his prison cell in Lovelady, Texas playing games if "catch me if you can."
Well from all of the articles and research I have done it appears that the crime was properly investigated. Several officers remarked about lack of a crime scene and that in itself hamstrung there ability to do the job the way that had hoped. The house was combed for hair and fibers, and 60 prints were taken from the location. The party goers were checked as well as a large number of clients, most of this information has been quoted throughout the threads. In my investigation of the investigation, I feel ok with the effort that was given early on. Now as far as Cox goes, I am openminded about him being responsible, but there is a lack of information about him. Bundy went from careful in his crimes to a psychopath. Is it common for a psychopath to refine his abilities to a careful calculated killer as Cox would have had to do? It would be interesting to see what cities he was in and when with his work. He is a heavy suspect in the I-70 killings based on his proximity to the killings, he was caught in Texas because of his stalking of a local tanning salon if I recall correctly. I will find the articles and post them later. His locations of work in the Springfield area is what I would look at first, then vehicle, and associates and there vehicles. Unfortunately this is not easy information to obtain.
