Physician’s Odyssey

Zhang Zhen and Su Tao exchanged greetings, and asked each other about the latest situation, and then turned to the topic, discussing the recent frequent serial murders of imprisonment in Hanzhou.

Now Hanzhou is full of rumors, Jiang Qinghan is still recovering from illness, and was forced to join the investigation of this case, which shows how much pressure the Interpol of Hanzhou has been under.

Zhang Zhen brought relevant information about the case, including the victim's information, the scene photos and related evidence where the corpse was found, and the criminal portraitist of the Criminal Investigation Team to outline the offender's crime based on the modus operandi, scene layout, and criminal characteristics. Mentality, so as to further predict their race, gender, age, occupation, appearance characteristics, personality characteristics and even the next step.

In history, many serial killer cases were solved with the assistance of this profession.

According to reason, these materials cannot be released to the public, but Su Tao's identity is different. He is an expert hired by the Hanzhou police and is qualified to know the details of some special cases.

The criminal portraitist judged the criminal as a middle-aged man about 42 years old. He was about 1.68 meters tall. Although he was not tall, he was very strong, with thick eyebrows and thin eyes. He liked to smoke, so his teeth were very dark. , Not particularly neat.But he is well dressed and likes to wear a white shirt and leather shoes.

Although many criminal portraits have been drawn, it is still very difficult to match criminals. After all, there are so many people in the world and there are many people with similar looks. This alone cannot explain anything.

Su Tao read all the materials carefully, frowning and said with emotion: "The murderer's tactics are extremely vicious, not only killing people, but also insulting the body, which is really heinous. Judging from the murderer's proficiency in committing crimes, he is a criminal with high intelligence, and a woman he likes. They are all around 20 years old and look good. As for their profession, they have one thing in common, that is, a shop assistant or a female college student. From a psychological point of view, the murderer should like to stay in the mall or university, and wait for the victim’s living habits to become familiar. After that, he will start again so that he can cover up the traces of the crime."

Zhang Zhen was startled slightly, but Su Tao's point of view was very novel, and asked: "Can you analyze his career?"

Su Tao listed a few photos together and frowned. Although he was knowledgeable, he also sighed that the pictures were cruel and bloody, and said solemnly: "The profession should be a civil servant or a public institution worker."

"Can you tell from these photos?" Zhang Zhen looked at Su Tao in confusion.

"The life of a civil servant or a staff member of a public institution is relatively easy. 9 to 5 is the biggest commonality. Although the time of the victim's disappearance varies, and the body was found at different times and places, the exact time of death was all In addition to the working hours of civil servants or public institution staff, there are more than a dozen cases before and after, it cannot be said to be a coincidence." Su Tao analyzed patiently, "Like this cruel murderer, the victim will be imprisoned. In the secret room, he tortured slowly and fully satisfied his inner evil desires before killing the victim. If he is at work, he definitely does not have that kind of leisure, so he chooses to torture the victim outside of work. Of course, This is just an angle to solve the case, not 100% accurate."

Zhang Zhen's eyes lit up and said, "If we can identify public officials, then the scope of criminals can be greatly reduced. The big deal is to conduct random inspections on all male public officials in Hanzhou."

Jiang Qinghan frowned, analysing Su Tao's point of view. Although his judgment seems to have no scientific basis, it still makes sense.

The criminal may consider certain details and leave no evidence at the scene of the killing, but this is a serial homicide that has lasted for many years. The criminal did not realize his own habits, but formed a pattern, and he did not find out. It is also difficult to change.

Su Tao is a doctor of traditional Chinese medicine. He chooses to approach it from a different angle from ordinary people. Judging this case is like a diagnosis, and he will consider the problem from a macro perspective.

Su Tao is now diagnosing chronic diseases.

The vast majority of chronic diseases are caused by people's bad habits or diet, so seeing a certain chronic disease can infer the life habits of a certain patient.For example, patients with chronic pharyngitis generally like to smoke, and patients with alcoholic liver generally like alcoholism.

Su Tao drew a common conclusion from the time of death of these victims. They all died at a time other than nine to five. The most impressive thing about nine to five is the public officials and the suspects. The IQ is very high, which is also in line with the quality characteristics of this group of people.

With the advancement of science, modern criminal investigation technology has developed extremely fast. Although the suspect is cunning, there are still some clues on the scene, such as hair, blood stains left during the scuffle, etc. Through these residues, it can be carried out. DNA matching.

However, with so many people in Hanzhou, you can't match all the men at once, so you need to narrow the scope. If you start with public officials, you will have a good breakthrough.

If the crowd is reduced, then there is a concrete way.However, the cases of prisoner murder in secret rooms are all over the province and the scope of public officials is still too wide.

Zhang Zhen frowned and said, "I start collecting samples every day."

Jiang Qinghan shook his head, and said, "There are at least tens of thousands of male public officials in Hanzhou, and if the criminals are not permanent residents, but they are migrants who commit the crime, it takes so much effort, but nothing can be accomplished, which will cause extreme damage. Big negative effect."

Zhang Zhen was silent, Jiang Qinghan considered enforceability, and it was indeed difficult to move forward.

There are so many public officials in Hanzhou, and they are highly hierarchical. If you rush to make such a request, it would be nice to find out the results. If you can't find out the results, wouldn't it make some leaders become angry and find a way.

Seeing Su Tao furrowed his brows, Jiang Qinghan knew that he was still analyzing other possibilities, and asked, "Are there other discoveries?"

Su Tao shook his head and said, "I have to go to the campus of Hanzhou University and Jinheng Business District to take a look. Maybe I can find some inspiration."

If you want to find the criminal's motive for killing, you have to go back to the source, understand the criminal's mental state, how he looks for prey, then sort out his clues and implement the killing plan.

Since the suspect has targeted the salesperson and college students in the mall, he may find clues faster by carefully studying these two places, at least more reliable than the method of finding a needle in a haystack proposed by Zhang Zhen.

Hanzhou University can be regarded as a second-rate school in the province. The school is located in several places in Hanzhou, and it is a comprehensive university formed by the merger of multiple institutions.Zhang Zhen came to the Fenhe campus with about 15,000 students, which is the largest campus of Hanzhou University.

There was a security guard at the school gate, but it was useless. Zhang Zhen showed his ID, and the security opened the door and let the Grand Cherokee in.After parking the car, the three people walked around the campus casually, because they didn't know that the criminal would stand there to lock and spy on the target.

The Fenhe campus has good greening. There is an artificial lake full of various trees. Even in the afternoon, you can still see couples hiding in the shade of the trees and chatting love each other.From this detail, it can be seen that the management of this university is very lax, so there is a dead end in law and order, so that the criminals can take advantage of the abduction of female students directly from the school.

Zhang Zhen looked around, looking for surveillance, shook his head and frowned, "Hanzhou University has already killed two college students. I didn't expect the school to pay so much attention to it, and the surveillance cameras are useless."

Later, Zhang Zhen complained to Su Tao that he had spent a lot of money in the campus safety project, but he really needed to provide video materials, but found that many cameras in the school were not turned on. The safety project became a face project and the money fell to the leadership. His pockets are really ironic.

Su Tao didn't expect Zhang Zhen to be very angry, shaking his head and smiling bitterly. Since the criminal has such a high IQ, he must know where the surveillance equipment is and where the equipment is a display. Even if the surveillance cameras are all turned on, the criminal can still avoid these crimes.

Su Tao walked backwards towards the southeast along the lake, and saw many young female college students who like to sit around the lake, and sighed secretly. They may think that studying and studying by the lake is very emotional, but they don’t know what they are lurking. The killer is staring at them.

The three discussed as they walked, and finally stopped in front of a small forest.On the periphery of the woods are birch trees that are commonly seen in Hanzhou, separating the trail of miscellaneous trees from the road. From a distance, the miscellaneous trees are also placed with a rockery made of gravel, and there is a small pool next to the rockery. The area around the pond is made of bamboo.

Although it was in the afternoon, it was sunny, but the miscellaneous woods could not be seen through, estimated to be two to three hundred meters in depth, the criminals were blessed to commit crimes.People are not necessarily killed here, but they are most likely to be controlled here and then moved to other places.

Jiang Qinghan looked around. Such a quiet place is really hidden. He sighed and said: "The school has left such a place to provide criminals with conditions for committing crimes. There are many incidents that have not been dealt with so far. People are angry."

Su Tao suggested: "Let's go in and see!"

Only after finding the first scene can we find the second scene after the transfer.

Because this is not the spot where the body was found, the police did not isolate it before, but the murderer must have laid out a lot of details here to prevent others from seeing the traces.

Su Tao has been observing the ground. Although it is a mixed forest, the ground is extremely clean, and there is no waste paper, beverage cans and other garbage. This makes Su Tao a little strange. In theory, although the mixed forest is very deep, it is suitable for couples to date. Haunted, will inevitably produce all kinds of garbage.

Of course, there is another possibility, because campus accidents happen frequently, so many students dare not come to the grove.

Zhang Zhen's eyes were bright, he suddenly squatted down and said excitedly: "Come and see, I have a major discovery!"
