I actually wondered this also. I have a great grandmother that has this same look. As soon as I saw the postmortem photo, I immediately thought "gypsy" which is what my great grandmother's surname meant.
The blue color tattoo also makes me wonder if she was in the jail/prison system at some point. Perhaps done by a pimp or an inexpensive tattoo at the time.
I took her photo and cleaned it up a bit with Paint. I am not very good at it but it is a bit cleaner and I cropped out the wounds. Her fingernails appear to be painted red and there is a mark on her hand that could be a defensive wound. This was an angry, personal murder, someone close to her did this. JMO
