Melissa Ann Shepard, born in 1935 in Nova Scotia, became known across North America as the “Internet Black Widow” for her pattern of marrying or befriending older men before drugging, defrauding, and in some cases killing them. In 1991 she was convicted of manslaughter for the death of her husband Gordon Stewart, whom she drugged and ran over twice with a car. Years later she served time in the United States for defrauding an elderly man she met online, and in 2013 she was again imprisoned in Canada for poisoning another husband, Fred Weeks. Her crimes revealed a chilling pattern of manipulation and predation, hiding behind the mask of charm and companionship.
