The Herrin Massacre took place in June 1922 in Herrin, Illinois. Following an early morning gunfire attack on non-union miners going to work on June 21, three union miners were killed in a confrontation after the striking union members marched on the mine. The next day, union miners killed 19 of fifty strikebreakers and mine guards, many of them in brutal ways. A twentieth victim from the non-union group would later be murdered, bringing the death total to twenty-three.

Scott Doody visited a cemetery in Herrin in 2009. He wanted to see where 16 of the nearly two-dozen massacre victims were put to rest in the 25-acre cemetery. He planned to take some photos and later share the experience with his radio audience on WXAN-FM. He found that the victims' graves apparently were unmarked and cemetery officials no longer knew of the locations. Four years later, Doody, with the help of the Williamson County Historical Society, a forensic anthropologist, an historian, two geologists, and others, a partial success can be reported.

This is a fascinating look at the history of the labor movement in the United States.
