In 1904, over four days, white mobs lynched 13 Black men in St. Charles, Arkansas. Despite being one of the worst such incidents in U.S. history, little has been said about it for more than a century. Mary Hennigan, a graduate journalism student at the University of Arkansas, has spent months researching what happened and talked with descendants of those murdered. Her reporting is part of the Printing Hate project from the University of Maryland's Howard Center for Investigative Journalism.
