Glenn Ford, who spent nearly 30 years on death row in Louisiana for a murder he almost certainly did not commit, died on Monday in New Orleans, less than 16 months after his conviction and death sentence were vacated and he was released. He was 65.

William Most, a lawyer for Mr. Ford, said the cause was lung cancer, a diagnosis Mr. Ford received shortly after his release in March 2014. He died at a home provided by Resurrection After Exoneration, a nonprofit group that assists freed prisoners, Mr. Most said.

Mr. Ford walked out of the Louisiana State Penitentiary at Angola, one of the nation’s toughest prisons, after spending 29 years, 3 months and 5 days behind bars, nearly half his life, most of that time in solitary confinement for all but an hour a day.

After years of failed appeals, Mr. Ford’s extraordinary release was precipitated by “newly discovered and credible exculpatory evidence,” as prosecutors described it. In 2013, it was provided by a confidential informant to Dale G. Cox, then the first assistant district attorney and now the district attorney for Caddo Parish, which includes Shreveport.
