Someone at a newspaper is opening Andy's envelope.
Cut to the warden in his office, looking at a headline reading: Corruption, Murder at Shawshank. Yeah, his butt is pretty much toast.
Slowly putting the pieces together, Norton flips through the Bible that Andy had him put into his safe the night before…and notices there is a rock hammer-shaped hole in the pages. Man, that guy thought of everything.
Outside the prison, a cop arrests Captain Hadley, who was obviously also ratted out by Andy. Your tower sniper days are over, sir.
Red tells us he heard that Hadley cried like a baby when they took him away.
Back in Norton's office, the warden watches Hadley being led away. He locks his door, loads the gun, aims it at the door, then aims it at himself and blows his brains out.
A while later, Red gets a blank postcard in the mail. It came from a town right on the Mexican border. Either Andy escaped to Mexico, or the border patrol is really hard up for friends.
