The adult Doe (and the two who are probably her biological children), based on the forensic Isotope analysis (O16/O18 ratio), were born and raised, and spent the last few months in a region that would cause one's O16/O18 ratio to be consistent with the Manchester NH area. While they could have been from some limited area in the east or a larger swath of land in the South West, it is reasonable to conclude that they were from southern NH and were living there when they were murdered. It is hard to imagine that a woman with a husband. Two children and a step child, could go missing without generating a missing person report or prompting any possible leads when their bodies were found. Yet, most likely, that is what happened. In that era, I think it was more likely for young people to be estranged from their families due to lifestyle choices. I think it was also the belief of Law Enforcement that many people who lived certain lifestyles associated with drugs, permissive sex and certain styles of dress, were inclined to pack up and leave without warning so that they would not warrant missing person report or listing.
The mystery within a mystery is the middle child who was "Bob Evans'" biological child. Her O16/O18 ratio indicated that she had living the last few months in the same area as the others but was born and raised in a different area: possible in the upper Mid-West or in norther New England, near, or perhaps over, the border into Quebec.
In 1980, " Bob Evans" reported that he had a wife named Elizabeth Evans. She appears to be "gone" by late 1980 and he is with Denise and her young child by 11/81. It is very likely that Elizabeth is the adult Jane Doe.
That have been reports that "Bob Evans" had been married to a Denise La Port who was supposed to be from French Canada. Could she be the mother of the middle child? If she raised the child in Quebec, it would be consistent with the O16/O18 ratio of the middle child, but what became of her. Either she was murdered by "Bob Evans" or she is alive and missing a child. But, there is nothing on any data base that points to her.
Somehow, the disappearance of these people managed to occur without being posted on the major data bases of missing persons. Perhaps now the publicity will generate some leads.
