How was Lora Skaggs ruled out? Her Namus page still says DNA samples submitted - tests NOT complete.
Re: home permanents -- Goodness that brings back memories. My mother, my grandmother, and I used to get together and all do our perms together. It was fun. We never had any problems, but then we can read and follow directions
If it was a home perm, were they things you could do on your own or was it a two person job (eg to make sure you got even coverage of the lotion at the back of the head)? If it was a two person job it looks as though it was done fairly shortly before her death as there's nothing I can see in the morgue photo to suggest it had started to grow out.
My MIL does all of her perms her self, and they turn out very well.
This woman now has a NamUs casefile with a very clear postmortem photo:
