Early life
Maria Swanenburg was the daughter of Clemens Swanenburg and Johanna Dingjan. After Swanenburg's first two daughters died at a young age, she married Johannes van der Linden on 13 May 1868. The result of this marriage was five sons and two daughters. The marriage lasted until 29 January 1886.Her nickname was "Goeie Mie", bestowed because of her amiable, neighbourly assistance with babysitting and taking care of the poor, sick, and elderly in Leiden, where she herself lived.
Murders
Her first victim was her mother Johanna, in 1880; not long thereafter, she poisoned her father, Clemens.It was established with certainty that Swanenburg poisoned at least 102 people with arsenic between 1880 and 1883. Twenty-seven of her victims died, of whom 16 were her relatives. The investigation included more than 90 suspicious deaths. 45 survivors sustained chronic health issues after having ingested the poison.
Swanenburg's motive was the payout of her victims' insurance or their inheritance. She had secured most of the insurance policies herself.
