Jane Toppan was an Angel of Death who killed over 31 people, but it is thought it was more to the hundreds.  She created her own concoction of morphine and atropine, and that became her poison of choice.  This was a female serial killer like no other. She would get sexual gratification from seeing people dying. She was labeled “Angel of Mercy” by the newspaper.  She is one nurse you never want to meet.
