The man next to the bed wanted to kill the man in the bed, because his big eye bothered him, and disgusted him.
He killed him by putting a blanket over his head until he couldn't breathe. The man's heart was beating so hard, he could hear it!
The man then cut up the rest of the body, and stored in his floor. He heard the police ring the doorbell, so he put on some normal clothes.
The man gladly showed the police around the house, knowing that they wouldn't find it. The man heard a strange pounding sound. The heart was beating! It was beating so loud, but the police didn't hear a thing.
The man got so guilty after hearing the heart, that he confessed to the police what he did, and showed them the buried body parts.
