 A teenage boy is found dead on a construction site. He appears to have suffered multiple blunt force traumas on his whole body. The murder weapon is likely a hammer. A ripped fabric found in his hand leads the investigators to a young girl who knows the deceased. Another case is very puzzling. A woman dies from a bullet wound in the chest while trying to break a fight between her present husband and her ex-husband. None of the men have GSR on their hands and no gunshot was heard.
