 An Oklahoma man has been executed after spending nearly 40 years on the state's death row. CBS's Jim Cressula reports. 66-year-old Richard Rogem was put to death for the 1984 stabbing death of his 7-year-old former stepdaughter. He always maintained his innocence, recently telling a state parole board. An innocent man doesn't ever plead guilty to a crime he hasn't committed. And the reason for that is obvious.
