"I feel wonderful," Fleming said outside court. "I've always had faith. I knew that this day would come someday."
Asked about his plans: "I'm going to go eat dinner with my mother and my family, and I'm going to live the rest of my life."
From the start, Fleming told authorities he had been in Orlando, Fla., when a friend, Darryl "Black" Rush, was shot to death in Brooklyn early on Aug. 15, 1989. Authorities suggested the shooting was motivated by a dispute over money.
Fleming had plane tickets, videos and postcards from his trip, his lawyers said, but authorities suggested he could have been in New York at the actual time of the shooting, and a woman testified that she had seen him shoot Rush.
The eyewitness recanted her testimony soon after Fleming's 1990 conviction, saying she had lied so police would cut her loose for an unrelated arrest, but Fleming lost his appeals.
The defense asked the DA's office to review the case last year.
Defense investigators found previously untapped witnesses who implicated someone else as the gunman, the attorneys said, declining to give the witnesses' or potential suspect's names before prosecutors investigate them.
And prosecutors' review produced a hotel receipt that Fleming paid in Florida about five hours before the shooting — a document that police had evidently had since they found in Fleming's pocket on arresting him, Mayol and Koss said.
Patricia Fleming, 79, was with her only son in Orlando at the time of the crime. She testified at his trial, but the jury evidently didn't believe her.
"I knew he didn't do it, because I was there," she said. "When they gave my son 25-to-life, I thought I would die in that courtroom."
Still, she said, "I never did give up because I knew he was innocent."
The exoneration, first reported by the New York Daily News, comes amid scrutiny of Brooklyn prosecutors' process for reviewing questionable convictions — scrutiny that comes partly from the new DA Kenneth Thompson himself. He unseated longtime DA Charles "Joe" Hynes last year after a campaign that focused partly on wrongful convictions on Hynes' watch. Hynes had created a special conviction integrity unit to review false-conviction claims, but some saw the effort as slow-moving and defensive.
Thompson took office in January. In February, his office agreed to dismiss the murder convictions of two men who had spent more than 20 years in prison for three killings, saying newly discovered evidence had raised substantial doubts about their guilt.
