"Interrogator": "Okay, so how did they all die, and what weapons were used?", 
"Interrogee": "Firstly, the masked men had a knife and a gun. One had a knife, and one had a gun. So they killed the old man with the gun. And then they saw the man, and the two masked men; one of them was killed by the knife, and the others were killed by the gun. And the two persons who were crossing the apartment were killed by the gun."
