Ear

Jimmy got caught because of the ear print that he had left whilst listening to the tumblers falling as he busted into the pete.
And Pete was picked up attempting to jimmy the strongbox open.
Joey was caught red-handed with his fingers in the till.
Fingers ran into a fence. The fence was caught with the ice and ended up in the cooler.
Red had been casing the joint but he wasn't concentrating on account of smoking another joint at the the time. Naturally, he ended up in the third joint with the rest of the gang.
