Detective: Start with capturing and retrieving the dog

Chapter 235
"What psychology expert is so bold and dares to question my husband?" On the plane, Zhao Linshan asked unconvinced, "Don't you know how many cases my husband has solved?"

"It's normal. Things in psychology are often controversial." Han Xin yawned and said, "But don't worry, your husband, I am still very confident in my profile. The main reason for going this time is Self-proof, there is a gap between this conventional psychology and criminal psychology, and people who are not experts in this field generally cannot guess accurately."

"This 'guess' is very useful." Zhao Linshan nodded with satisfaction, "Go get some sleep. I'll call you when I get there."

"No, you owe me. You were so late last night..." Han Xin knocked her little head.

After a short nap, the plane landed at Nanhua Airport at 08:30 in the evening.

Although he has indirectly cooperated with the local police several times, this is the first time for Han Xin to come to this famous magical city.

He had heard how cruel the competition here was. After graduating from college, he didn't dare to work here at all, fearing that he would become one of thousands of stepping stones.

In the end, you still have to come here to prove yourself.

After getting off the plane, Han Xin and Zhao Linshan went straight to the local public security bureau.

The criminal police captain in charge of the case this time is named Ma Yuanbin. He is 1.8 meters tall, with a muscular body and a thick body. At first glance, he looks like a bear rushing towards him. Han Xin was so frightened that he almost gave him a hand that split his muscles and bones. Unloaded.

"Consultant Han." Ma Yuanbin came forward excitedly, held Han Xin's hand and shook it vigorously, "Oh, really! I have wanted to see you for a long time! Although seeing you definitely means someone has died, but still, I am so happy to see you. !”

"Well, thank you. This is my wife and assistant." Han Xin was so shaken by him that he couldn't speak.

"Really? This is your Watson." Ma Yuanbin turned to Zhao Linshan and smiled, "The little girl is quite handsome."

Zhao Linshan smiled happily and bowed in response, while Han Xin took out his hand: "Without further delay, let's discuss the case."

"Yes, please come this way." Ma Yuanbin said, leading Han Xin inside, "Just a few hours ago, the forensic report from the forensic laboratory came out. Do you want to take a look?"

"Please let me take a look." Han Xin nodded.

Ma Yuanbin ordered a little policewoman who was following him: "Go and bring the autopsy report to Consultant Han."

Soon, we arrived at the conference room, where everyone was gathered here to discuss the case.

"Consultant Han is here, please be quiet." Ma Yuanbin reminded the people at the scene.

Immediately, Han Xin took the autopsy report from the little policewoman who came in.

This time, although the victim was beaten, the cause of his death was "spinal cord injury caused by dislocation of the upper vertebrae."This statement was a bit hard to pronounce, so Han Xin directly looked at the photos of the victim when he died.

Seeing this, Han Xin immediately raised his eyebrows: "This neck..."

According to the tips provided by the "Knowledge Reserve", this technique is called "forehand pivot twist", which is the kind of "twisting the neck" that you often see in movies. With a click, the person is gone.

But it seems easy in movies. In fact, breaking a person's neck is not that simple. It requires the right angle and strength. It is a special skill that can only be used by trained people.

Moreover, this technique is used to kill the enemy, not to subdue the enemy like grappling, so it will not be used in various fighting competitions.

Based on this inference, the murderer should be a soldier or a special police officer with special training, just as Han Xin had inferred before.

The other party's occupation is relatively special, which can explain the origin of stress disorder. The strong sense of self-blame caused by "I didn't save that child" is what caused his PTSD.

During the forensic examination, it will only report that the victim's cause of death was a broken cervical vertebra, and there is no way to know these details.

"That would be much simpler." Han Xin said to himself, and then explained to everyone at the scene: "The murderer is a retired soldier or policeman. I guess he suffered from traumatic stress disorder due to a certain mission, that is, It’s often called PTSD. This symptom is common among soldiers and police. I guess he may have failed to save the child during some mission.”

"That's why I get sick when I see someone hurting a child..." Ma Yuanbin said suddenly.

Han Xin nodded: "I think it is very likely that he was forced to retire because of this stress disorder, and this condition has been tormenting him, making it impossible for him to engage in normal work, and eventually he was reduced to picking up garbage for a living." Zhao Linshan said with some sadness: "He has obviously made such a great contribution to the country and the people, but in the end he ended up like this. He also became the murderer he least wanted to be. Isn't this too heartbreaking?"

Zhao Linshan's words directly silenced more than a dozen people at the scene. They were all police officers, and they could all deeply feel the experience and pain of the prisoners.

He dedicated his youth and even his health to the country and the people. In the end, in the days when he should have enjoyed life, he became a homeless man because of his self-blame, making a living by picking up garbage. Now he has become the person he was arrested for back then. arrested prisoner.And he didn't even do it voluntarily, but because of a stress disorder that caused him to have delusions.

Putting it into perspective like this is simply heartbreaking.

But at this time, a person suddenly said: "However, the psychologist we consulted said that this person should have a normal life, so we did not find him. He only digs through the trash when he is sick."

Ma Yuanbin glared at the speaker fiercely, scaring the young man so much that he shrunk, but he still said stubbornly: "Everyone makes mistakes. I heard from friends in Beichang City that the last arson case was also a guess." I made a lot of mistakes."

Regarding the other party's statement, Han Xin could only smile bitterly.

It is true that he guessed wrong in many places in the last arson case and then corrected it, but Han Xin reminded him from the beginning that it is difficult to confirm the psychology of such a prisoner with an extremely unstable mental state.

That is to say, he could only guess part of it. If the normal police were to investigate, it is estimated that the number of victims would have to reach 70 before the murderer could be caught.

The ignition delay device alone took the police a long time to find.

"Then let's think about this theory. What kind of stress disorder does he have that makes him dig through the trash?" Han Xin asked with a smile, "Also, even if he has a normal life, he will definitely be discovered by the surveillance camera, right? He just doesn't go through the trash, and he doesn't disappear completely. So this statement obviously cannot be explained logically. Looking at my theory..."

Han Xin changed the subject: "If the other party is a trained soldier or criminal policeman, it can explain why he can't be found. He has received professional training and has anti-tracking capabilities. And this..."

Speaking of this, Han Xin pointed to the final key point, which is the autopsy report: "The deceased died of spinal cord injury caused by dislocation of the upper vertebrae, that is, the neck was twisted. I would like to ask if everyone at the scene has learned the forehand. Is this a pivot technique? It is called 'COW' for short in foreign countries, and it is a technique only learned by special forces."

The detectives looked at each other and then shook their heads.

"Right? Because the police generally do not learn such deadly tricks. Only a very small number of special policemen and special forces can learn such tricks." Han Xin replied, "If it is an ordinary person who lives a normal life, he Is it possible to master this technique? You know, it is not easy to break the victim's neck when he is defensive."

With that said, Han Xin came behind Zhao Linshan, grabbed her chin and top of her head respectively, and then gently twisted: "When the other party is on guard, his neck will exert force to resist, and it will be difficult to break it at this time. His neck. What is the correct technique? First turn to the left, trick the victim into resisting, and then suddenly follow his force and twist to the right..."

Han Xin patted Zhao Linshan on the head and looked at the criminal police at the scene: "I believe that even you don't know this detail, right? And even if I know this technique, I can't control the intensity when using it in practice. It's a little lighter. The victim cannot be killed. Therefore, the person who killed this second victim cannot be an ordinary person."

As he spoke, Han Xin pondered: "Considering that the prisoner is a retired soldier, and has experienced failure in changing jobs due to PTSD, and has been picking up rags for a living for some time, he may be around thirty to forty years old."

"Well, it is indeed reasonable and reasonable. This statement makes sense." Ma Yuanbin nodded and smiled, and then glared at the young detective who had just questioned, "No one has any objections now, right!?"

The young man lowered his head and did not dare to speak, but Han Xin planned to show his hand again.

Because Han Xin's ability is now more sophisticated than when he was investigating the arson case last time.

"The following are some of my personal speculations, based on some details, logic and my personal intuition. Everyone should just take it as a gamble." Han Xin cleared his throat.

Ma Yuanbin nodded: "It doesn't matter, as long as you can catch someone, you have to give it a try."

"Based on this age, we considered the major events that happened in our country during that time." Han Xin nodded, "It should be the anti-drug operation launched in Lanyun Province in [-]. Maybe he was an armed police officer who participated in that operation Or SWAT. He may have witnessed the horrors in action and suffered from stress disorders, which ultimately led to his retirement."

"Isn't this too specific?" Ma Yuanbin said in shock.

"The above point is just my wild guess. You can try it, but don't force it. If you can't find it, just divide the range based on the previous ones." Han Xin smiled modestly, but to be honest, he was still very confident about this conclusion. Confidence.

After all, this time he mainly wanted to prove himself, so of course he had to show off his skills.
