Black Widows of Liverpool dating history

Details

Catherine Flannagan (1829 – 3 March 1884) and Margaret Higgins (1843 – 3 March 1884) were Irish sisters who were convicted of poisoning and murdering one person in Liverpool, Lancashire, England and suspected of more deaths. The women collected a burial society payout, a type of life insurance, on each death, and it was eventually found that they had been committing murders using arsenic to obtain the insurance money. Though Catherine Flannagan evaded police for a time, both sisters were eventually caught and convicted of one of the murders; they were both hanged on the same day at Kirkdale Prison. Modern investigation of the crime has raised the possibility that Flannagan and Higgins were known or believed by investigators to be only part of a larger conspiracy of murder-for-profit—a network of "black widows"—but no convictions were ever obtained for any of the alleged conspiracy members other than the two sisters.
