A wrongly convicted Philadelphia man who spent nearly three decades in prison before he was released last year was gunned down at a funeral, authorities said Wednesday.Williams had been convicted in two separate cases, a triple murder in 1989 and the slaying of Michael Haynesworth, who was also killed that year.Decades later, Philadelphia prosecutors moved to dismiss the murder convictions against Williams in both cases after having found tainted testimony and exculpatory evidence that police discovered but never shared with defense lawyers, officials said.Since his release 22 months ago, Williams had been working as a carpenter with hope of starting his own construction business that would employ freed convicts, said Williams’ longtime attorney, Stuart Lev."And that his short-lived freedom was marked by struggle, as Pennsylvania is one of 12 states in the U.S. that does not compensate the wrongfully convicted, is unconscionable.""
