When Luo Chuan had just checked the body, he had already seen that the police officers on the bathroom had waved at him twice, so he asked Tian Zhen and Ke Xue to investigate the body first, and then came to the bathroom to see what the police had discovered.

I saw that the police officer at the door of the bathroom said to Luo Chuan with some excitement: "Come in and take a look, this guy is simply bold." In the years I've been working, I've never seen a murderer like this! He committed the crime in a raincoat, gloves, and shoes of unknown importance, without fingerprints, footprints, or traces. It's like seeing a ghost in this house! After committing the crime, he not only cleaned these crime tools in the bathroom, but also put them here for us after washing! This is an absolute provocation. The inspectors were very excited to report the results of the investigation to Luo Chuan.

Luo Chuan cautiously walked into the bathroom, looking at the raincoat in the bathtub, the gloves on the sink, and the blood soaked in the bathtub. The color of the blood was obviously hideous, but this bathroom was not a mess at all. This proves that when the killer came in to clean these things, he was methodical and not flustered to deal with the traces. If nothing else, the only DNA that can be detected is probably the deceased.

Luo Chuan stood where the murderer had stood before, looking in the mirror. I thought to myself: With such an abnormal psychological quality as the murderer, did he stand here a few hours ago, smug at himself in the mirror? Does the piano music he repeats over and over again have any special meaning? Killed three people, unknowingly, and no trace has been left yet. If it weren't for the exaggerated modus operandi, it would almost have made people wonder if there had been strangers in this house. And he brought so many tools to commit the crime, why did the victim let him in? Is it really a stranger...... The successful killing of two women and a man, but there are no traces of a fight in the room, on the surface, makes people suspect that an acquaintance committed a crime, or even a gang.

However, Luo Chuan knew in his heart that this criminal was deceitful and ruthless. The modus operandi is peculiar, and he is high-profile and conceited. Therefore, it is not possible to determine now whether it is an acquaintance who committed the crime.

As for the possibility of the gang committing the crime, Luo Chuan felt that it could also be basically ruled out. Because it is almost impossible for the team to work together to the point where there are no mistakes at all. Everyone's psychological quality is different, their behavior habits are different, even if they are all master crimes, there will be some subtle deviations caused by habits. This murder scene, not like.

Luo Chuan walked out of the bathroom and said to the police officer next to him: "None of us want to rest tonight." Investigate the scene carefully and try to find some clues. ”

The police officer asked with a headache: "Captain, this time the criminal is not ordinary!" You said he put the corpse like that, isn't it psychopathic? Or...... Mentally ill? ”

Luo Chuan smiled: "Whether it is mentally ill or not depends on the experts, tomorrow morning, I have to visit an old friend." No one knows this kind of morbid/psychological murder case better than him. ”

The police officers worked all night, and Luo Chuan did not dare to slack off for a moment to seriously analyze the clues of the entire crime scene. It wasn't until the sky began to dawn that he walked out of the villa, stood in the small garden in the courtyard of the villa, and lit a cigarette.

It's the season of spring again, and the dew is crumbling on the petals. The aroma of earth and grass can make you forget the strong smell of blood in the villa for a moment. The breath of spring came to his face, which made Luo Chuan, who had not relaxed all night, feel a little soothed.

And at this moment, on the other side of the city, the outer door of the key isolation ward of Castle Peak Psychiatric Hospital is also opening heavily. Several doctors followed a clean, handsome man with an extraordinary temperament to the front of the room.

The doctors said to the man with a little worry: "Mr. Guan, your name is like thunder in our industry. But...... These extreme pathologies that you are about to meet are also thunderous in their past sins. Some of them will use their bodies to attack people, and they don't feel any pain about it! They're crazy and hard to control, are you sure you want to see them directly without protection? ”

Guan Shan casually flipped through the file in his hand twice, and said lightly: "This No. 37, he said that he was painless, whether it is true or not, I don't know yet." Didn't you call me here just to verify whether he is really a mentally disordered patient and whether he has a clear consciousness and ability to act? All the evidence showed that he had poisoned a neighbor's family of five, but he did not admit his guilt. The file says that he identified himself as a ...... Moldy bread. ”

Seeing this, Guan Shan shook his head and smiled: "How lethal can a loaf of bread be?" You don't have to worry, just take him to the opposite room, and I'll talk to him alone. ”

The two medical staff looked at each other, but Guan Shan insisted so much that they had no choice but to start preparing for security and taking the patient to the opposite consultation room.

Three days ago, the dean made a special explanation that it was rare to invite Guan Shan, and asked them to fully cooperate. You know, Guan Shan is the youngest and most capable top psychiatrist today. Since engaging in the forensic psychiatric appraisal industry, he has identified thousands of criminals who pretend to be mentally ill. He is also an expert in criminal psychology, so to speak, and it is impossible for any criminal to escape the punishment of the law by pretending to be mentally ill. Not mentally ill, he'll definitely see it. He is mentally ill, and he also has the grasp of guiding the confession of the criminal process. He had been abroad for a long time, but he suddenly returned to China half a year ago and started working as a professor at a criminal investigation school. The specific reason is not yet known, but Guan Shan's ability represents absolute authority and professionalism.

This time, the reason why he came to "consult" before dawn was actually to paralyze the patient. A normal person's sleep routine is natural, and four or five o'clock in the morning is exactly the time when a person is the most sleepy and weak-willed. At this time, asking the patient if he is mentally ill can easily reveal his flaws.

Guan Shan entered the consultation room and sat down in his place. He looked at the video recording equipment on the table and made sure there was no problem, then called in patient No. 37.

Two paramedics walked in with a tall man with a blank face and a restraint suit designed for psychiatric hospitals. This garment is very special, the armpit sleeves connect the main garment and the sleeves, controlling the patient's hands. There is a strap between the legs, which not only does not affect the normal movement of the patient in a small area, but also can effectively restrain the patient's movement, so as to avoid the accident of the patient scratching, self-harm, collision and other injuries. It is also made of strong tensile fabric, and the hollow design of the hands in the middle of the abdomen leaves a slipknot while restraining it. When the patient is agitated, the knot will struggle tighter and tighter.

After letting the man sit down, Guan Shan said to the two medical staff, "You guys go out first, and I'll call you later." ”

The two doctors were still a little worried and said, "Mr. Guan...... This person is really dangerous, otherwise we would still be here with you! In case he goes crazy, there will be a response. ”

Guan Shan smiled and said, "It's okay, with the restraint clothes, he can't do anything." I'll shout at you if there's something. ”

Seeing this, the two doctors had no choice but to wait outside the door for the time being.
