I know who did it... I saw him that night. His name's Iemitsu Sawada. It was a big mess. Someone used my dad's old artifacts to start some trouble, when they started investigating my family someone killed a bunch of people that man worked with. There was an investigation by his boss, but it was just dismissed. He's still got the same job and everything.
