Death-row inmate Curtis Flowers, a Mississippi man tried six times for the shooting deaths of four people in a furniture store in Winona, Miss., in 1996, is pictured in a July 1, 2010, photo. The U.S. Supreme Court ruled June 21, 2019, to overturn Flowers' conviction, saying that by consistently keeping black jurors off the jury the local prosecutor violated the Constitution.
