The old man's vulture eye drove him mad, he couldn't stand it. It sharpened his senses and he could hear all things from the heavens and the earth.
Every night for 8 days Poe stalked the old man. He creeped into his bedroom with a lamp as quiet as a mouse waiting for the darkest night.
On the 8th night it was pitch black. He could run around and the old man wouldnt see a thing. Then he suffocated him slowing down his heart, and killing him. Then he chopped him up and placed him under the wood boards.
The neighbor heard a shriek and called the cops to check in on them. Poe acted like everything was fine and that he was just house sitting for the old man.
Poe trying to make it less obvious, invited the police to sit down after a good days worth of work but placed himself right above the body. Then the police wouldn't stop laughing and Poe thought they were making fun of him. He finally confessed to killing him.
