If you know, the case will be solved.

It's common, but it just shows that the real bad guys don't have to be cruel.

It is normal for the murderer to hide in the crowd without being found.

In fact, the so-called key to solving the case is not necessary to be so dogmatic. According to the characteristics described by the victim and so on, those are not necessarily useful.

Now I see many people guessing who the murderer is online.

Some people say it's a gigolo, but I can't say that gigolo is very young. Although his hands are soft, his age can't be said to have burned the face of a fool when he was a child.

That handsome guy didn't cooperate with the interrogation. This is a confrontation against extorting a confession by torture. He was a cynic at that time.

Fool's dad, I don't think so. If he abused the fool so much, why did the fool call him dad when he was forced to testify against the crime scene?

A fool likes to watch a TV program about the police with his father and watch TV where he is tortured. He also said that he would call his father, which only shows that his father can have certain anti-reconnaissance ability if he keeps watching that kind of program. Well, maybe.

A fool's father cannot have soft hands. He always cooks barbecue. Even if he often wears gloves, that kind of work will make his hands thicker.

Beating cops aren't. He later broke a leg and limped for years. The little girl didn't mention that ordinary people are disabled.

Some people say that the woman of the leading police officer pretended to be a man and committed a crime. I think that's nonsense.

If the boiler man is the real murderer, it makes sense. He appeared in the camera without gloves. Many conditions are more suitable, but I am so stupid. If he is the real murderer, the police will eventually cry. If the police suddenly understand, won't they arrest him? How can you say at the beginning of the movie that the case has not been solved? What do our audience think? I think the police who have been handling cases for many years will also react.

So my conclusion is, don't guess. The killer can't guess how many times he watches the movie, can he? Sorry, I only watched it once, and now I think it's a good movie.

The above vernacular is what I said casually out of my love for this film. Please forgive me if some friends think it is wrong.
