Well, I know DNA testing is used all the time to convict people and also as of late, to exonerate people that were wrongfully convicted before DNA testing was available......so yeah, apparently it is very accurate.
I’m guessing that they traced the DNA from the skull to a match from one of those DNA family tree sites. But I thought that would just get you to a relationship - not great-great grandmother or whatever it was.
Although I suppose with a match to another person on the website they could narrow it down pretty closely. Probably also used forensics to determine the age at death and when she died, location, etc.
Interesting stuff. I’m glad that she had a proper burial and it wasn’t a murder with her body stuffed in a wall.
