This is my first post. I have done a lot of research on this unidentified couple and am fascinated. It is so hard to believe they have not been identified in all these years. I don't think their murder will ever be solved but I am hoping they will be identified.
Here is my take:
I am inclined to shy away from the Canadian theory. Firstly, I am not certain the report of meeting Jock Doe at the KOA was factual. Why did it take this man so long to come forward? Why wasn't there reports from other campers or people from the area that remembered them? I would think this young attractive couple would have stood out to people. They say Jane Doe was exceptionally pretty....people (especially men) would have noticed her and remembered her. But, there is only one man who said he thinks he recognized them as guests that were staying at the KOA...and he came forward after a length of time. Just doesn't add up to me. Also, I have a hard time believing that if they were in fact Canadian that someone would not have come forward and said they knew them- a friend, acquaintance, classmate... somebody.
Through DNA testing, they have been proven to be unrelated. But, their features were so similar that at one time it was thought they may be brother and sister. This makes me to think they were from the same ethnicity. Their olive skin tones could point to South America. Taking all this into account, I keep coming back to the missing Argentine couple, Maria Marta Vasquez and Cesar Lungones.
I know this theory is weak to some people because Maria Marta was supposedly pregnant. But, this has never been proved and was only said on the basis of one person's testimony. The man who made these statements was named Scilingo and he was an Argentinian military official. Scilingo made the statements about Maria Marta being pregnant and giving birth after looking at a picture her mother showed him. I have read that he later recanted that statement anyway and he was a total flake. Because there is no real proof and possibly recanted statements, Maria Marta's pregnancy and purported baby son may be just conjecture. I have read suggestions that Cesar's brother was friends with a priest (Christian Von Wernich) that was complicit in the kidnappings and murders of the desaperacidos and that Von Wernich arranged for them to be exiled to the US.
The timeline adds up as do many other things. I have read many places that Jock Doe appears to have come from an affluent family. His elaborate dental work is one of the reasons cited. But, if he was raised in an upper class family, how did his teeth get bad enough that he would need a whole mouth restoration? Experts have said the dental work was most likely not done outside the USA. This also fits with the Argentine couple- the work was done in South America. Also, it would explain why the work was only half way completed. Maria Marta and Cesar were kidnapped and exiled- preventing the completion of the dental work.
The biggest reason that I think they are the Argentine couple is the pictures. The know pictures of Maria Marta and Cesar are so so very similar, I find it hard to come to any other conclusion. Look at this picture of Cesar compared to the crime scene photo of the unidentified. Their body type is exactly the same....long and skinny. Maria matched the death photos of our Jane Doe to a tee also. SOmeone has pointed out that Maria Marta has a widows peak and the unidentified Jane Doe does not. BUt if you look at this picture of Maria Marta, the widow's peak is not there. Could she have held on side of her hair up with some kind of clip or bobby pin? The pictures are so grainy, it is hard to tell.
The really frustrating part of all this is that it would be so easy to rule them out and make us go back to the drawing boar . They must have some family that could provide DNA to compare The family could simply confirm or deny that Maria Marta had moles on her face and calf or that Cesar had surgery on his shoulder at one time.
