NewsdayTV's Proving Innocence tells the extraordinary story of Keith Bush, convicted of a Long Island teen's 1976 murder and imprisoned for 33 years for a crime he always said he didn't commit. Decades later, new evidence revealed Suffolk County authorities hid information pointing to another suspect, leading a judge to vacate Bush's conviction. Newsday's Thomas Maier reports on how Bush finally proved his innocence and reclaimed his life.
