On the morning of July 16, 1996, someone walked into a furniture store in downtown Winona, Mississippi, and murdered four employees. Each was shot in the head. It was perhaps the most shocking crime the small town had ever seen. Investigators charged a man named Curtis Flowers with the murders. What followed was a two-decade legal odyssey in which Flowers was tried six times for the same crime. He remains on death row, though some people believe he's innocent. For the second season of In the Dark, we spent a year digging into the Flowers case. We found a town divided by race and a murder conviction supported by questionable evidence. And it all began that summer morning in 1996 with a horrifying crime scene that left investigators puzzled.
