I don't think she is Patty. For one thing, this Jane Doe was rather far along in her pregnancy and there is no evidence that Patty was pregnant at all from what I've read, much less far along. Yeah, maybe if she was pregnant and trying to hide it, her husband may have thought (I'm assuming rightly?) that it was someone else's child and that could have been what led him to kill her..as well as thinking she wasn't faithful to him. I know I read in addition she had dated someone else earlier that year when she was on a break from her husband who she was trying to leave, and of course he would have been aware of that. Patty and Patty's daughter do resemble this Jane Doe, but I think it is just too far fetched of a match. It would be nice to solve both mysteries.
