How many women killed their husband over insurance money?

It's difficult to determine an exact number of women who have killed their husbands specifically for insurance money, as many cases may go unreported or be classified under different motives. However, there have been notable cases throughout history that highlight this crime, often portrayed in media and true crime stories. Research indicates that while spousal homicides occur, they are relatively rare, and financial motives are just one of many factors that can lead to such actions. Overall, the phenomenon is more a subject of sensationalism than a widespread trend.
