Was This Man The Tylenol Killer?

Did an Idaho investigator, looking into a local cold case, solve a 40-year-old mystery in Illinois? The production team at "Unsolved Mysteries" believes two cases may have been solved in one investigation: that a man, found dead in a Boise church in 1982, was the person who killed seven people with cyanide in Tylenol bottles around the Chicago area earlier that year. An upcoming documentary will make a case for this new suspect. Inside Edition Digital’s Mara Montalbano has more.
