An Oklahoma man used pandemic relief funds to have his name cleared of murder_我的网站

一 |     京冀携手推动仓储物流产业数字化智能化转型给仓库装上“火眼金睛”近日，位于石家庄市东信数字经济产业园的清瞳观界科技有限公司（以下简称“清瞳观界公司”）迎来新客户——BIGBUY中国公司总经理孙晓波。    GREENWOOD, Ark. -- Ricky Dority spends most of his days playing with his grandchildren, feeding chickens and working in the yard where he lives with his son's family.It's a jarring change from where he was just several months ago, locked in a cell serving a life prison sentence at Oklahoma's Joseph Harp Correctional Center in a killing he said he didn't commit. 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many old convictions resulted from overworked defense attorneys, shoddy forensic work, overzealous prosecutors and outdated investigative techniques.The problem is particularly acute given Oklahoma's history of sending people to death row, where 11 inmates have been exonerated since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.”。他此行的目的是深入了解智能视觉解决方案，进一步提升仓库管理效率。“我们已经与仓储物流领域多家国内外知名企业建立了合作关系。”清瞳观界公司总经理牛辉说，按照“北京研发、石家庄转化、全国应用”思路，企业将持续深耕机器视觉前沿领域，加速仓储物流产业数字化智能化转型进程。让仓库的“眼睛”更明亮智能盘点机器人在货架中穿行，整托盘点、散托盘点都能轻松应对，遇到黑灯、缠膜、污损、褶皱等难题还能提供一站式解决方案；识货宝机器人可实现多标签、多条码识别，能够做到同时识别上千个标签和条码，条码识别准确率高达99%，未识别部分可实时提醒作业人员按货物坐标复核处理……对孙晓波的到访，牛辉早有准备，他一边演示、一边介绍公司智能仓储领域系列产品的强大功能。BIGBUY是欧洲知名的B2B跨境电商平台，其仓储体系以自动化、分布式布局及供应链全链路可视化为核心特征。

二 | “入驻BIGBUY平台的品牌超8000个，平台可提供超40万种产品。”孙晓波说，现代化标准仓储普遍采用整托、散托混合存储模式，常态化盘点作业工况复杂，清瞳观界公司的产品，对提高智能仓库运营管理效率具有促进作用。在仓储物流领域，商品盘点一直是个难题，存在货物到仓才临时找库位、账上有货架上无货、账上无货架上有货、出库错发率偏高等痛点。其本质是传统仓储存在“看不见、算不准、反应慢”短板。在真实的仓库管理中，追求绝对的、理论上的“零误差”成本极高，几乎难以实现。清瞳观界公司是北京清瞳时代科技有限公司子公司。作为清华大学计算机视觉实验室成果转化平台，北京清瞳时代科技有限公司构建“视觉算法+智能硬件+场景数据”三位一体自研技术方案，做到了在复杂堆叠、缺陷标签、极端光照等70%以上特殊场景下保持行业领先识别率，在最大程度上实时掌握库存动态，帮助仓储物流企业打破效率瓶颈、降低运营成本。以智能盘点机器人为例，该产品运用清华大学计算机视觉技术，深度融合感知、边缘计算与AI决策能力，已在全国多个城市的大型仓库中得到应用。“产品的生产在石家庄，产品的质量验证、提升也在石家庄。”牛辉介绍，在智能盘点机器人生产和质量验证过程中，智能相机和搬运履带历经多次升级，才达到满意效果。能够做到业内领先的识别率，清瞳观界公司智能仓储系列产品上都搭载了自研的智能相机。
