After more than two decades behind bars, Dority had no chance at being released — until he used his pandemic relief funds to hire a dogged private investigator. The investigator and students at the Oklahoma Innocence Project at Oklahoma City University, which is dedicated to exonerating wrongful convictions in the state, found inconsistencies in the state's account of a 1997 cold-case killing, and Dority's conviction was vacated in June by a Sequoyah County judge.Now, the 65-year-old says he’s enjoying the 5-acre property in a quiet neighborhood of well-to-do homes in the rolling, forested hills of the Arkansas River Valley outside of Fort Smith. “If you’re gone for a lot of years, you don’t take it for granted anymore.”Dority is one of nearly 3,400 people who have been exonerated across the country since 1989, mostly over murder convictions, according to the National Registry of Exonerations. In Oklahoma, there have been more than 43 exonerations in that time, not including three new exonerations this year. The cases underscore a serious problem facing a judicial system in which many old convictions resulted from overworked defense attorneys, shoddy forensic work, overzealous prosecutors and outdated investigative techniques.The problem is particularly acute given Oklahoma's history of sending people to death row, where 11 inmates have been exonerated since 1981. The issue has pushed a Republican-led legislative panel to consider whether a death penalty moratorium should be imposed.In Oklahoma County, Glynn Ray Simmons was freed after spending nearly 50 years in prison, including time on death row, in a 1974 killing after a judge determined prosecutors failed to turn over evidence in the case, including a police report that showed an eyewitness might have identified other suspects.And just this week, Perry Lott, who served more than 30 years in prison, had his rape and burglary conviction vacated in Pontotoc County after new DNA testing excluded him as the perpetrator. Pontotoc County, in particular, has come under intense scrutiny for a series of wrongful convictions in the 1980s that have been the subject of numerous books, including John Grisham’s “The Innocent Man,” which he produced into a six-part documentary on Netflix. The most common causes of wrongful convictions are eyewitness misidentification, misapplication of forensic science, false confessions, coerced pleas and official misconduct, generally by police or prosecutors, according to the Innocence Project, a national organization based in New York.In Dority's case, he said he was railroaded by an overzealous sheriff and a state prosecutor eager to solve the killing of 28-year-old Mitchell Nixon, who was found beaten to death in 1997.Investigators who reopened the case in 2014 coerced a confession from another man, Rex Robbins, according to Andrea Miller, the legal director of the Oklahoma Innocence Project. Robbins, who would plead guilty to manslaughter in Nixon's killing, implicated Dority, who at the time was in a federal prison on a firearms conviction. Dority said he knew he didn't have anything to do with the crime and found paperwork that proved he had been arrested on the day of the killing.“I thought I was clear because I knew I didn’t have anything do with that murder,” Dority said. “But they tried me for it and found me guilty of it.”Jurors heard about Robbins' confession and testimony from a police informant who said Dority had changed bloody clothes at his house the night of the killing. They convicted him of first-degree murder and recommended a sentence of life without parole.After years in prison, while most inmates spent their federal COVID-19 relief check in the commissary, Dority used his to hire a private investigator, he said. Bobby Staton had mostly investigated insurance fraud, but he took on the case and realized quickly that it was riddled with holes, Staton said. He eventually turned to the university's Oklahoma Innocence Project, which assigned a law student, Abby Brawner, to help investigate.Their investigation turned when Staton and Brawner visited Robbins in the maximum-security Oklahoma State Reformatory in Granite, and he recanted his statement implicating Dority. “It was pretty intimidating,” Brawner said. “Especially when you're going in to meet someone who doesn't know you're coming and doesn't want to talk to you.”Brawner and Staton also learned the informant didn't live at the home where he told investigators Staton showed up in bloody clothes. When the actual homeowner testified at a hearing this summer, the judge dismissed the case.Dority's original attorneys were ineffective for not discovering the informant didn't live at the home, the judge said, giving prosecutors 90 days to decide whether they will retry him. That three months has been extended, and prosecutors have said they intend to ask the judge for more time for DNA testing. Dority, confident in his innocence, said he's not concerned about additional forensic testing.Sequoyah County District Attorney Jack Thorp and former Sheriff Ron Lockhart did not respond to requests for comment from The Associated Press. But Assistant District Attorney James Dunn, who is overseeing the case and was not in the office when it was originally prosecuted, said he agreed with the judge's dismissal after hearing the homeowner's testimony and learning a witness “was not credible.” “The last thing I want to see is an innocent person in prison for a crime they didn't commit," Dunn said. "Because that means the person who actually did commit the crime, or those persons, are still out there.” Meanwhile, Dority is learning to use a smartphone and the television remote control, he said. He's thankful to Staton and the Innocence Project and says his case proves others are wrongfully imprisoned in Oklahoma.“After they’ve done what they’ve done to me, I know there are people in that prison who are innocent that need to be out and need help getting out,” he said. “If they hadn’t gotten me out, I’d have been in there for the rest of my life.”。
二 | 这是一条跨越千里的“氢能大动脉”，将打造“张家口制氢枢纽、承德绿氢补给、唐山应用出口”的氢能产业协同体系。
三 | 眼下，位于张家口市康保县的可再生能源制氢和液化工厂一期项目，整套大型制氢、压缩、储运设备已全部安装完毕。工作人员正分组对电解水制氢机组、压缩机组、各类公辅装置等进行通电联调。
四 | 项目负责人王权介绍，作为华北地区重要绿氢供给基地，该项目立足康保县风光新能源装机资源，就地消纳本地富余清洁电力，实现清洁能源就近转化、就地利用，年内正式投产后可年产高品质绿氢1.2万吨。作为可再生能源制氢和液化工厂的二期项目，鸿蒙氢能科技离网制氢低温液化综合利用示范项目，已完成风光电源的构建和批复工作，年产14万吨的制氢工厂正在进行建设用地报批，同步办理环境影响评价报告、节能评估及永久使用草地手续。
五 | 两期项目全部建成后，预计氢气年产值达33.4亿元，全产业链年产值达135亿元，每年可减少二氧化碳排放635万吨。长距离输氢，是当前氢能产业发展面临的现实困境。作为目前全国设计口径最大、输氢能力最强、钢材等级最高的纯氢输送管道，康保至曹妃甸输氢管道工程的进展备受关注。
六 | 张家口海泰氢能科技有限公司是这项工程的规划建设方，该公司总经理白天明介绍，目前氢能的主流运输方式是用长管拖车运输高压气氢，但这种方式难以支撑氢气大规模应用。
七 | 同时，液氢运输方式受制于液化成本和技术装备水平，短期内存在瓶颈。相比之下，管道输送则展现出巨大优势。据测算，管道输氢成本可降至每百公里每公斤0.5元。康保至曹妃甸输氢管道工程已于2025年10月正式启动，目前正在全力推进环境影响评价、水土保持评价工作。工程投用后，不仅可以输送氢气，还将起到储氢库作用。省能源局能源节约和装备处相关负责人介绍，带动全国氢能产业技术水平提升，也是张承唐氢能区域试点项目建设的重要任务。当前，电解制氢缺乏统一的检测标准与规范，制约了高性能氢能装备发展。为解决这一问题，建设投资集团有限责任公司拟建设规模化可再生能源制氢系统及装备多场景实证实验平台。目前，该平台已完成土建施工，正在进行各专业设备安装，预计9月至11月开展设备单体及联合调试工作，建成后将形成可再生能源制氢一体化检测检验技术路线。按照试点建设计划，唐山低温低压蒸汽金属裂解制氢加氢一体站项目、张家口52兆帕铝内胆碳纤维缠绕气瓶氢气管束集装箱储运设备试点项目、唐山大容量高压气氢与液氢混合储存工程示范项目等，今年年底前将实现投产。张家口氢储能长时长效运行项目争取今年年底前达到兆瓦级发电状态。省能源局能源节约和装备处相关负责人介绍，到2028年，张承唐氢能区域试点将全面形成“制储输用研”全链条产业生态，助力京津冀能源结构转型，为全国跨区域氢能产业协同发展提供可复制的“张承唐样板”。
