Pat Nabong/Sun-Times A man tortured by Chicago police into confessing to the 1982 murders of two officers has finally heard the word he has doggedly sought for nearly four decades — innocent. After three trials and 36 years of incarceration, Jackie Wilson said he felt mixed emotions after his petition for a certificate of innocence was granted by Cook County Judge William Hooks on Friday. “It’s a long time coming,” Wilson said. “I’m not mad ... but I’m still suffering. This will remain with me for the rest of my life.” A week before, Wilson’s attorneys argued he was merely present — and shocked — when his brother, Andrew Wilson, grabbed the gun of Officer William Fahey and fatally shot him and then Officer Richard O’Brien during a traffic stop in Gresham.
