In the early 1900s, on a small farm in La Porte, Indiana, Norwegian immigrant Belle Gunness used strychnine to poison her suitors and boyfriends before feeding their remains to the hogs. Gunness's motive was to collect life insurance, cash and other valuables from her victims. To this day, her fate is disputed.
Meanwhile, between 1907 and 1917, in Windsor, Connecticut, nursing home proprietor Amy Archer-Gilligan purchased life insurance policies on her elderly residents before poisoning them with arsenic.
And finally, in Cordele, Georgia, greed led Janie Lou Gibbs, a church going mother and grandmother who once ran a day-care center, to poison her three sons, a grandson and her husband in the 1960s for the sole purpose of collecting life insurance.
And during the 1880s in Liverpool, England, sisters Catherine Flannigan & Margaret Higgins worked together to poison their own family members in an attempt to claim insurance payouts. The two sisters became known as "The Black Widows of Liverpool".
