One of the most famous instances of a threatened white woman leading to a black person’s death is Carolyn Bryant. Bryant lived in Money, Mississippi, in 1955 when she accused a 14-year-old boy of following her behind the counter of the store she co-owned, grabbing her waist and bragging that he had been with white women before. Later that evening, her husband and brother-in-law found this boy, forcefully took him from his relative’s home, lynched him and threw his body in the Tallahatchie River. The men were never convicted and later confessed to the murder a year later. The boy’s name, of course, was Emmett Till, and his death galvanized the civil rights movement.
