Reductio ad traumatum

In 1933, two servant girls in Le Mans, France, Christine and Léa Papin, murdered two of their employers.(1) Madame Lancelin and her adult daughter were bludgeoned and knived repeatedly, to the point of unrecognisability. Each had their eyes gouged out. The Papin sisters had spent much of their young lives in institutional care. Their family had a history of incestuous abuse, and at least one of their relatives had died by suicide.
