NEW YORK — Delbert Tibbs, who in 1974 was convicted of a Florida rape and a murder that he had nothing to do with, died on Nov. 23 at his home in Chicago. He was 74.
His death was confirmed by Andrea Lyon, a law professor at DePaul University who is godmother to Tibbs’s daughter Mahalia. Lyon said that the cause was uncertain but that Tibbs had had cancer.
Tibbs spent nearly three years in prison before the state Supreme Court reversed his convictions, vacated his death sentence, and freed him.
Tibbs then campaigned for the abolition of capital punishment and became one of six people whose stories of wrongful conviction and near execution were told in “The Exonerated,” a play by Jessica Blank and Erik Jensen. Full story for BostonGlobe.com subscribers.
