A Lynching Memorial Unveiled in Duluth: "The dedication drew thousands of people from all over the area. The emotional high point came with a speech by Warren Read, a fourth-grade teacher from Kingston, Wash., who had learned while researching his family that his great-grandfather had helped lead the mob that stormed the local jail and took the three men, who were circus workers, from their cells. His voice choking with emotion, he apologized to the victims and their families."
