it's been 2 years have you found it yet?One thing that confused me: How did they clean the crime scene, if the blood soaks into the floorboard, they'll need to do a thorough cleaning then cutout the soiled parts and replace it with new boards (which needs specialists). I forgot where I learnt this, from some manga about a guy working in a company that specializes in this... damn now I want to find out what that manga's name was.
