Flanagan, Catherine, 05/03/1884. 55 year old hanged at Kirkdale prison, Liverpool by Bartholomew Binns, side by side with her sister, Margaret Higgins (see below). 17. Higgins, Margaret, 05/03/1884. Flanagan and Higgins were both convicted of the poisoning of 44 year old Higgin's husband, Thomas, for his life insurance. He was not their only victim (there were at least 3) and they were not the only female poisoners operating in this area of Liverpool in the 1880's. As was usual at the time, the Crown simply prosecuted one capital case at a time and did not go for anymore if the first resulted in a guilty verdict and death sentence.
