In the middle of winter, a woman is found dead in her bed, with multiple stab wounds in the stomach. Soaked into the sheets is a massive amount of blood, along with blood drops on the carpet. On the side table beside her bed, there is a glass full of water mixed with blood. What was the murder weapon, where is it now, and how was she killed?



The murder weapon was an icicle; it was the middle of winter! The woman was stabbed with the icicle, and the murderer turned, which is how the blood got onto the floor, and placed it in the glass to melt, destroying the evidence.
