Reddened and boiled.

I'm sitting in front of my computer and plugging in the flash disk, I'm waiting for my computer to detect the flash disk, and then a notification appears on the screen. I click the folder inside the flash disk, I see four photos that seem like a document that has been scanned. I open the first photo and read the document so slowly since I'm still not good at reading Japanese words. This document is about the case of my parents' death, they know that my parents were killed not because of the fire accident, and it's written here that they're going to investigate more about the case.
