S1, E3: On the morning of July 16, 1996, owner Bertha Tardy and three of her employees were murdered execution-style inside her furniture store in the quiet town of Winona, Mississippi. All four died of gunshot wounds to the head. Twenty-six-year-old Curtis Flowers became a suspect almost immediately when investigators learned that he'd been fired from the store days earlier. No murder weapon was ever found, but a gunshot residue test conducted on that day revealed one particle on Curtis' right hand. Flowers was arrested and went on to become one of the most tried defendants in history with the same District Attorney presiding for 21 years over a total of six trials and overturned verdicts. Now he faces a possible 7th trial while he continues to maintain his innocence.
