Debora Green (née Jones; born February 28, 1951) is an American physician who pleaded no contest to setting a 1995 fire which burned down her family's home and killed two of her children, and to poisoning her husband with ricin with the intention of causing his death. The case was sensational, and covered heavily by news media, especially in the Kansas–Missouri area, where the crimes occurred. Though Green has petitioned for a new trial twice in recent years, her requests have not been successful.
