Being a criminal police officer isn’t always easy, isn’t it?

[Newspaper] Yesterday, September 26, 1967, saw a large fire at the major rail station. The total number of injured individuals is unknown. Most likely, a few gang members from the recently formed "Iron Vipers" gang set the fire. The police are investigating the cause of the fire; however, they have not released any information.

That is what the press reported, but as a higher-ranking police officer, you are more knowledgeable. There was one guy named "Soren Sinclair" who was a victim of the fire, wasn't he? After all, half of his face was scorched, leaving a large burn scar. However, several factors suggest that he may be a member of the gang. Now that he's out of the hospital, it's your job to determine whether Soren Sinclair is innocent or guilty.

All you have is his file, which includes numerous reports from his time in high school and a CV: "This week, Soren Sinclair smoked in the boys' restroom twice." "Soren Sinclair has received a week-long suspension for severely insulting teachers lately." "Soren Sinclair needs to retake this school year because he missed too many classes." A great deal more of those reports, too.

Now you walk into the inversion room, he sits there calm and even slightly smiling softly. His hair is made and he wears a gray suit. ‘His burn scar looks really hurtful’ you thought while sitting down.
