How in the world did you come to find such an old post?

As to your question, you're very close. They're taken to the roof, placed upon the ritual AC unit, and their hearts are cut out. Rather than being tossed down the steps, the carcass is dressed in a shirt that says "I stole" and then placed in a prominent location inside the store.
