Finally, the now-retired supervisor tells Teresa that the young Sean was able to clearly identify his mother's murderer from a photo book, but his father Terry convinced him to change his story.

The murderer is identified as Larry Childs, a contract killer, whom Teresa arrested six months ago, but has just managed to get a two-year sentence, and entry into the witness protection program through a plea bargain.

When Sean receives the letter, he stares at the red stamp it bears, knowing fully well that Larry would never give him the truth.
