I found this tonight, quite interesting. can't find any prior thread for Mary who is also known as Mary Doe 19. She died in May 1991.
"In late May an old woman, her insides ravaged by infection, quietly slipped from life at a Peoria hospital.
A few days later, a handful of people who'd tended her at a nursing home gathered in the rain to hear a minister whisk through a five-minute funeral.
There was little more to say because so little was known. In fact, no one knew who she was."
A lot more at link, but, not who she was.
