The info that this girl was originally thought to be a male was something I hadn't heard before. I see that there is a DNA profile on her. Shouldn't the DNA be able to tell for sure what the sex is? Although there is a case on Doe Network where partial remains were found and it states that a DNA profile was done but also says the sex and race are undetermined! Does that mean they weren't able to get a complete DNA profile or what? It makes you wonder about Snohomish Jane Doe, whether the DNA proved the sex or if it was determined by an anthropologist by pelvis shape, etc. She was dressed as a woman and had average sized feet for a woman. I think the absence of a bra is not that odd. A lot of young women in the 70s quit wearing them. She is tall for a woman, but not unusually so. I know several women who are that tall.
I also don't think they can go by the uneruption of wisdom teeth to judge her age. I got one wisdom tooth in my mid-twenties, another in my mid-thirties, and my dentist says I will never get the other two. I also have a good friend who got her first two wisdom teeth at the age of 38! She was also told the other two would never erupt. While it might be a little unusual to get wisdom teeth at an older age, this shows that it does happen.
As to which arm the watch was on, I am right-handed and wear my watch on my left wrist. I don't think I could buckle it with my left hand if I wanted to wear it on my right wrist.
If she was a runaway, maybe her family never reported her missing because they didn't care or because she was running away from abuse that they didn't want anyone to know about. Or maybe they knew she left voluntarily because it was a troubled family and they just assumed she made a life somewhere else. There are some cases on Doe Network in which missing teens had run away several times before, so maybe whoever was responsible for her was tired of trying to track her down and didn't report it. Also, there are cases from the 70s in which if you were at least 18 the police wouldn't file a missing persons report unless there were obvious signs of foul play. A good example is Jeanne Melville who disappeared at the age of 18 in 1970 but the police wouldn't file a report. So when a body was found in the same state a little while later, there was no missing persons report to match the person to. She was just positively identified this year! Maybe Snohomish Jane Doe left home voluntarily in the 70s and no report was ever filed by police. Sometimes these unidentified teens make me wonder if the family does know the body was found but don't want to come forward because they are hiding something from the past, perhaps sexual or physical abuse in the home.
Anyway, just some thoughts.
