Maria Swanenburg received the nickname Goede Mie (Good Me) because she loved to care for the children and ill people in her poor neighborhood.
Over the course of three years, she poisoned every family she worked for, starting with her own parents.
She would then collect the inheritance of the deceased, claiming she earned it for her services—often leaving no money to cover a burial. Some of her victims managed to escape death but sustained irreparable damage.
The survivors eventually led to her discovery.She was caught in 1883 and tried for 90 murders—but found guilty of only three.
She was sentenced to life in a correctional facility, where she died in 1915.
