Back in Paris, Weber was arrested for vagrancy and briefly confined to the asylum at Nanterre, but doctors there pronounced her sane and set her free. She drifted into prostitution, picking up a common-law husband along the way. On 8 May 1908, the couple settled at an inn in Commercy. A short time later, Weber was found strangling the innkeeper's son, 10-year-old Marcel Poirot, with a bloody handkerchief. The father had to punch her three times in the face before she would release the lifeless body.
