A man convicted of fatally stabbing his 11-year-old niece and dumping her body in rural Oklahoma was executed Thursday. Jessie James Cummings Jr., whose personality and habits were compared to Charles Manson's, reiterated his innocence before being executed. "The justice system let me down on this case. It turned a blind eye to truth in this," Cummings said. "Today, you came here to see an innocent man die." He gasped twice during the six-minute execution and died at 6:11 p.m. Cummings, who was married to two women, was convicted of killing Melissa Moody, whose remains were discovered near a county bridge in 1991.
