FILE – This undated file photo provided by the South Carolina Department of Archives and History shows George Stinney Jr., the youngest person ever executed in South Carolina, in 1944. Supporters of Stinney plan to argue Tuesday, Jan. 21, 2014, that there wasn’t enough evidence to find him guilty in 1944 of killing a 7-year-old and an 11-year-old girl. The black teen was found guilty of killing the white girls in a trial that lasted less than a day in the tiny Southern mill town of Alcolu, separated, as most were in those days, by race.
