You walk through an alley on your way home and find a man beating up some guys. He notices you

"Move along, before I kill you too." He said with a cold tone.

You decide to leave them alone, seeing how violent the man was.You got home, and decided to watch some TV. You saw in the news that multiple men were found dead at X Street. The same street you saw that violent man. Then, you heard a knock on your door.

A deep, husky voice called out, "Open the door." It was the violent man.
