He escapes from prison half a dozen times, and one of the times to be a shithead in a cold prison "YOU CANT TRAP ME" and he snaps the cuffs with just his hands.
They put him into some super tight security after that annnnd he escapes.
The old metal for cuffs back then wasn't as good as modern prison infrastructures, and the cold weakened them further so a chink in the chain probably happened, and that man has superhuman feats.
