When Guan Shan followed Luo Chuan into the scene, the body was about to be carried away. Guan Shan looked at it roughly, then frowned and said, "I seem to understand why you are looking for me." ”

But Luo Chuan shook his head and said, "No, you still don't understand. With that, he took Guan Shan to the stereo in the hall and gently pressed the play with his gloved hand. The melodious piano music instantly sounded again.

Guan Shan looked at Luo Chuan with some puzzlement and asked, "Is this ...... What was it like at the time of the crime? ”

"That's right, I want to ask you, under what state of mind and mentality did the murderer listen to Beethoven's piano music while doing that kind of thing to a corpse?"

"Do you suspect the killer is a psychopathic murderer?" Guan Shan asked.

Luo Chuan shook his head a little confused and said, "I'm not sure either." It's just that this method hasn't been encountered for a long time, and there are no flaws on the scene. The only thing he left was this piano piece. ”

"Give me fourteen minutes and don't bother me." After Guan Shan said this to Luo Chuan, he stopped talking.

He stood in the middle of the living room, his eyes slightly closed, and it really took him fourteen minutes to listen to the whole piece thoroughly.

The police officer on the side was dumbfounded, and couldn't help but whisper to Luo Chuan: "Captain, which master did you invite?" What was he doing there? What time is fourteen minutes? It looks so mysterious! ”

Luo Chuan looked at Guan Shan, his eyes full of appreciation. He replied in a low voice: "There are three movements in the Moonlight Song, the first movement is six minutes, the second movement is more than two minutes, and the third movement is five and a half minutes, adding up to exactly fourteen minutes. What we do is to restore the crime scene with traces and evidence, and what he does is to restore the criminal mind. ”

The officer scratched his head, puzzled. Because this song "Moonlight" is so familiar, do you still use it to listen to it here from beginning to end? There's always a sense of pretense......

Luo Chuan saw the policeman's questioning, so he explained very seriously: "Are you in a state of mind when you listen to piano music in the concert hall and listen to piano music in the crematorium?" Again, it will not be the same at the crime scene. Standing here, Guan Shan was able to use this only clue to judge the basic psychological model of the criminal and the psychological dynamics of his murder. ”

“…… It's just too profound. The officer laughed wryly.

Luo Chuan also smiled and said, "That's why you are interning here, but he is already a professor at the Criminal Police Academy." ”

At this time, Guan Shan came over and said to Luo Chuan thoughtfully: "This person really reminds me of the reason why I returned to China. He's not your average criminal, and he's more callous than you might think. He can walk between society and crime with ease, grace and calmness, which is a large part of the reason why he can enter the door with a murder weapon. ”

"Why Moonlight?" Luo Chuan has always been obsessed with this piano piece. He felt that the person who could play this kind of music when he killed someone must not be an ordinary prisoner. But what kind of emotions are hidden in this song? This can only be answered by Guan Shan. If you understand the psychology of the killer playing this song, you may know the reason why he killed.

In 1801, Beethoven fell in love with a woman, and it was from this that the song "Moonlight" was born. His passion for love, the torment of illness, the sorrow of his heart, and his stubbornness, sometimes frustration, sometimes pride, are almost all reflected in his works in 1802. If we stand in the murderer's point of view, there is sorrow and anger in his heart, as if everything has reached an irrepressible edge, and this piece is like a great and poignant madness. From the first note like a lament, sorrow comes from it. ”

"Crazy white? To whom? Decedent? Luo Chuan asked in surprise.

"No, by no means. He was looking for something, but he couldn't get it. Because of this, Luo Chuan, I have to tell you very bad news. "Moonlight" will sound again, and his murderous behavior will not stop. Guan Shan said to Luo Chuan very solemnly.

"A piano piece...... Can you really express that much? A few police officers who came around couldn't help but ask what they were thinking.

Guan Shan explained professionally: "From an artistic point of view, it is just a piano piece. But if you start from the behavior at the crime scene, then it contains the state of mind of the criminal. No criminal would play music at the scene of his own murder for no reason. The first movement of Moonlight is lamentation, the second is memory, and the third movement is an emotional catharsis, full of anger, grievances, and protests...... His state of mind is like the sea, with undulating waves that are difficult to stop. I can responsibly say that he killed this person at random, with no real purpose. It's just getting started. ”

Luo Chuan handed Guan Shan a photo, which was a line of inscription under the deceased. He asked Xiang Guanshan, "Do you have any opinion on this?" Luo Chuan's meaning was obvious, of course he didn't want this murderer to kill randomly. Because if that's the case, it's going to be even harder to catch him. If you can't grasp his criminal tendencies, you can't know where to start.

Guan Shan glanced at the photo, seemed to sigh slightly, and said: "Since you know that I returned to China for the unsolved case a year ago, then you should also know that if this case and the criminal I am looking for are really the same person, I really don't know whether to report good news or bad news to you." ”

Luo Chuan gritted his teeth and said with some anger: "I really don't know what's going on in this world, why are there so many psychopaths?" Why aren't they in a psychiatric hospital, but rushing to prison? Or perhaps...... It's our working relationship, and we've seen more perverts/perverts than normal people. ”

Luo Chuan was originally comforting himself, but who wanted Guan Shan to analyze it very seriously and methodically on the side: "There are 252 people born every minute in the world, 4.2 people per second, and it is conservatively estimated that the proportion of psychopaths in the general population is 0.05%, which means that a psychopath is born every 47.6 seconds." Between 2000 and 2010, there were more than 16,000 homicides in the United States each year, and more than 20 percent of the mentally ill offenders in prisons. Almost all of the murderers behind the murder of law enforcement officers are psychopaths. In the 2011 census, it was found that there were about 68873400 adult men in the United States, and if one in every 150 adult men met the criteria for psychopathy, then 459156 men in the United States were psychopathic. There are about 2266832 inmates in the U.S. prison system, and about 1772073 are left, excluding women, juveniles, and men over the age of 50. If 20 per cent meet the criteria for psychopathy, it proves that 354414 people are being detained. That is, in the United States, 77% of psychopaths are in prison. Their crime rate is so high that no matter what you do, it doesn't change the fact of this data. Guan Shan said with a relaxed face that surprised Luo Chuan.
