Thomas Shipp and Abram Smith

Thomas Shipp and Abram Smith, both African Americans, were lynched on August 7, 1930 in Marion, Indiana. They had been arrested the night before on charges of robbing and murdering a white factory worker and raping his girlfriend. A large crowd broke into the jail with sledgehammers, beat the men, and hanged them. Police officers in the crowd cooperated in the lynching. A studio photographer, Lawrence Beitler, took a photograph of the dead bodies hanging from a tree surrounded by a large crowd; thousands of copies of the photograph were sold.
