You had just gotten off work and were quite tired. As you were heading home, you heard voices coming from a narrow and dark street. You didn't pay much attention and thought it might be a cat. But then instead of these sounds you heard some screams. You were worried but also curious. Finally, you went out into the street to see what was there and were shocked by what you saw. Before you was a man covered in blood, holding a human arm and a freshly murdered corpse.
