The heavy rain fell steadily throughout the night while the detective carefully examined evidence found at the murder scene location. A body lay motionless on the floor with a knife stuck in the chest indicating foul play of some sort. The dim lights flickered briefly revealing bright red blood splatters covering the walls around the unfortunate victim in the room.
