I go back and forth a lot between believing this is the work of a lone perp. I always doubted Cox was responsible for this, especially if it was a "one-man show". But, if there was indeed two or more involved in the abduction, it's definitely possible to believe he could have been one of them. The phone calls the following day could indicate this wasn't the work of a single perp, and to me, it seems like Cox would be exactly the type of guy to toy with the friends and loved-ones in that manner. I don't really think that the claims those calls were completely random and unrelated to the crime hold much water, especially when you look at the very specific times those came in.
As I mentioned, Cox as a lone perp does seem unlikely, at least to me. From reading about his criminal history and the documented interviews with him, he seems like someone who would not be able to carry off a crime of this nature and leave no evidence behind. Everything was methodically thought-through, it would seem. Cox would likely have sexual motivations and I don't see any reason he would have to remove the women from the house if he were working alone. It's a horrible thing to say, but I truly believe if he were the perp, the house would have been a likely murder-scene and this case would have been solved very soon after.
What I can say, and I believe it to be true, that it was stressed over and over that the abductor and the killer or killers were not one and the same. It was also evidently determined that a gun was used to gain compliance. How that was determined I do not know.
We are not getting any definitive information beyond somewhat vague statements from the SPD.
I will say this. It is now my opinion that the police figured this out at the outset. When someone flunked the polygraph and if the same one had a "terrible alibi" that almost certainly points in one direction.
I would also go back to the latest quote I cited a few posts back. The time frame was such that the perp could not be eliminated. To my mind the individual is a virtual certainty. However, who carried out the murders is truly not known (at least by me.) It would be very helpful to know who he was hanging out with at the time. If it is that family out in Rogersville, it would certainly fit and the bodies could have been buried there.
One has to really parse the statements to understand what is being said. That is why I will be very interested in further statements they provide if any.
Offhand, is there a source here that provides all of the statements by the police? That would be helpful.
BTW: I believe I have located the source of the "poor choices" quote. It was not (I believe) a statement by the police but of a poster here who made one final post. I know of no police statement that cast doubt on any of the victims as somehow responsible for their demise.
I just located this quote among the media sources here:
Regarding the polygraphs, there was one person who did NOT pass it.
Quote: "The men passed the 20th and 21st polygraphs given in the
investigation, now 46 days old. All but one person has passed the tests, indicating they were telling the truth about the questions asked. No details were released on the person who failed the test." End quote. News-Leader, July 23, 1992
