National Forensic Doctor

after lunch.

Wei Zhenguo and his men slowly arrived at the Changyang City Criminal Police Detachment.

The criminal police detachment in Changyang City, the provincial capital, is a large unit with multiple criminal police brigades under it. Its level is the same as that of Ningtai County. The Criminal Science and Technology Center under its jurisdiction is also of brigade standard. The laboratories it builds are the largest and most diverse. In terms of quantity, they are several times that of the provincial department.

At the same time, the Changyang City Criminal Police Detachment also has its own office building, a large building with a total of 12 floors, which inherently has the air of being unattainable for a small local police station.

Inside the building.

Small conference room.

The air conditioner whined, protesting that there were too many people in the room.

The chairs that had been temporarily moved in were piled up randomly and occupied the space. Even the spider plants on the windowsill had been moved away, leaving only a few leaves scattered on the ground, helpless like a few little ones being cleaned. lobster.

At this time, more than ten criminal police officers were sitting. The most conspicuous one is the one sitting near the door, with a slicked back hair and dark shiny hair with two stripes and three stars.

When everyone comes in and sees this person, they will be shocked and feel that this person is extraordinary - at this age and level, he is indeed very extraordinary.

Jiang Yuan came in, and his eyes couldn't help but roam around on his long back and shirt.

Most of the other detectives have short hair that is easy to take care of, and their shirts are messy and dirty, but this one has a meticulous hairstyle and a spotless shirt. It's like a hairless cat squatting among a group of long-haired cats. Something feels weird.

"We are all here. Let me introduce to you. This is the fourth-level senior police sergeant of our provincial criminal investigation bureau, Liu Jinghui, Liu Chu and the third-level senior police chief Gao Qiang Gao." Sitting inside is the captain of the criminal police detachment. Yu Wenshu saw Jiang Yuan and others arriving and immediately began to introduce them.

Liu Jinghui was a young hairless cat with a slicked back hair. He stood up politely and nodded to everyone.

The section chief Gao Qiang next to him was an ordinary man, about forty years old, with dirty clothes and no personality.

Yu Wenshu, leader of the criminal police detachment, introduced Wei Zhenguo, Jiang Yuan and others.

Wei Zhenguo stood up in a very social manner, apologized to everyone, and said: "The road conditions are not familiar, and the people who came here may have been slow, making everyone wait for a long time."

"It's okay, we made time to come over." Yu Wenshu ended the topic with one sentence, and then began to introduce the criminal policemen of his team.

In a small conference room, criminal police officers from three levels gathered together, making everyone realize that there must have been a major change in the case.

Within the police system, the relationship between provincial departments, municipal bureaus and county bureaus is not subordinate, but only a business guidance relationship. This is similar to agencies such as the Department of Agriculture, the Department of Finance, or the Bureau of Education.

The County Education Bureau must listen to the business instructions of the Municipal Education Bureau, but when it comes to important issues such as personnel and financial rights, the County Education Bureau listens to the county government, and the Municipal Education Bureau listens to the city government, and they are not subordinate to each other.

Similarly, the criminal police brigade of the county bureau also obeys the county bureau and the county government in terms of personnel rights, and its business is independent of the criminal police detachment of the city bureau. The criminal police detachment of the municipal bureau has its own criminal police brigade and can only command its own criminal police brigade. When it comes to the county bureau, it can only provide supervision or business guidance at most.

When it comes to the Criminal Investigation Bureau or Criminal Investigation Corps of the provincial department, its nature has not changed much, but there are fewer business components. The vast majority of the criminal investigation bureaus of provincial departments do not handle cases themselves, and the criminal investigation bureau is just an ordinary department within the provincial department.

However, in such a condensed provincial criminal investigation bureau, not only all of its internal personnel are masters and experts, but it is certainly not easy to send them out to supervise cases.

With the participation of the Provincial Criminal Investigation Bureau, the excitement of the criminal police officers present continued to build up.

"Next, I will read to you the relevant documents on the 326 disappearance case, now called the 326 kidnapping and murder case, as well as the arrangements for the reorganization of the task force... I will be the leader of the task force, and the deputy leaders are Liu Jinghui, Gao Qiang... ..." Yu Wenshu's responsibilities in the city bureau are equivalent to Huang Qiangmin's responsibilities in the county bureau, but the platform is 100 times larger.

Wei Zhenguo, deputy captain from the Sixth Squadron of the Criminal Investigation Brigade of the Ningtai County Bureau, as well as Jiang Yuan and others, did not have the slightest chance to express themselves at the meeting hosted by Yu Wenshu, and only listened to him reading documents and speaking.

It took nearly 10 minutes before Yu Wenshu brought the topic back: "Based on expert judgment, it is initially believed that Tan Yong, the principal culprit in the 326 kidnapping and murder case, was involved in more than one murder case."

Woohoo.

What made the noise was the sound of the electric fan.

Everyone was very calm.

Seeing people from the provincial department show up, it's like digging out a man wearing your clothes from the bedroom closet. He can't be here to repair the air conditioner.

Similarly, if only one person died in the Tan Yong case, wouldn't it be redundant if the provincial department also sent two people?

"Liu Chu, please tell me." Yu Wenshu gave up his position.

"I'll just say it here." Liu Jinghui stood up and said: "There are several doubts about the 326 murder case. First, the principal culprit Tan Yong said that he kidnapped Ding Lan as an impulsive act out of shame and anger after his courtship failed. His purpose was to He threw her by the highway to scare her, and then he became impulsive again and developed into rape... rape... rape... After rape, he wanted to take Ding Lan back to his house, kill her and bury her body, but because of Ding Lan's plea, , turned into digging basements for imprisonment.”

Liu Jinghui glanced around with sharp eyes and said slowly: "The most unreasonable thing here is that Tan Yong brought Ding Lan back to Changyang City. From Ningtai to Changyang City, you have to pass through a toll station and conduct random inspections. , it is unreasonable to take such a big risk just to bring Ding Lan back to his vacant house to kill and bury his body. Tan Yong must have concealed the key points during the explanation process."

Liu Jinghui looked at the reactions of the surrounding criminal policemen and continued: "Tan Yong is a construction worker. He knows how to use construction vehicles. He has a familiar construction site and has many options for disposing of corpses. He claimed that he excavated the basement to bury the corpse, because Ding Lan With his begging and active service, he decided to switch from burying corpses to digging basements... Is this more difficult and risky than burying corpses in the wild or at a construction site? Is it necessary? Especially the excavation of basements requires some machinery. , Tan Yong made a special trip to transport it, it’s not easy.”

"In addition, Tan Yong committed at least four crimes, including the female corpse we excavated from the basement. He was also a prostitute. He subsequently kidnapped and prostituted prostitutes three times, but he did not leave much evidence, proving that he had a more rigorous mind. Why would such a person leave fingerprint evidence on Ding Lan’s bicycle?”

When Liu Jinghui said this, he looked at Jiang Yuan.

Jiang Yuan looked at Liu Jinghui curiously. This was his first time participating in the task force.

"Where is Liu Chu's inference?" Yu Wenshu knew that Liu Jinghui liked reasoning. At the same time, he had used many reasonings to prove his strength in the Criminal Investigation Bureau, so he did not challenge his "authority" at all.

Liu Jinghui looked around and saw no one answered. He felt a little disappointed. He raised his chin slightly and said, "I tend to believe that Tan Yong told part of the truth."

"You said it." Yu Wenshu cooperated.

Liu Jinghui nodded with satisfaction and said: "First, leaving fingerprints shows that Tan Yong's kidnapping of Ding Lan was probably impulsive, but it was not a random crime. Because Ding Lan was chosen as the target of the kidnapping, he did not commit adultery. It’s convenient for women. He could just choose a target at random in the provincial capital and complete his crime.”

Liu Jinghui paused and continued: "At the same time, Ding Lan is the first woman imprisoned in the basement. Her special characteristics can indeed explain why he changed from burying corpses to digging basements and imprisoning."

Some people nodded, but most people remained calm. What Liu Jinghui said here was just ordinary reasoning. Many people present could do it - but most of them did not dare to say it publicly with such certainty.

Liu Jinghui narrowed his eyes in enjoyment. What he liked most about reasoning was the power that burst out from calmness.

After briefly describing the case, Liu Jinghui spit out the word he had saved for a long time:

"But! None of these answers can explain why Tan Yong returned to Changyang City!"

Liu Jinghui's suddenly raised voice attracted everyone's attention.

Several detectives couldn't help but frown and start thinking.

"Indeed, he can abandon the body on the spot, or go to a construction site he is familiar with, or even go to other counties and cities, but he should not return to Changyang." A criminal policeman from the Changyang City Criminal Police Detachment pondered and said: " He is someone who often runs outside, so he should have seen the road inspections in the provincial capital."

"That's right. Tan Yong's company is an engineering company affiliated with the Road and Bridge Group. It has business all over the province and builds various roads, including expressways, national highways, various toll stations and checkpoints... So, he chose There must be a very strong reason in Changyang City." Liu Jinghui expressed his reasoning and said: "I think Tan Yong has a familiar and proven plan for abandoning corpses."

The criminal policeman who just spoke asked: "Maybe he happened to think of a suitable construction site in Changyang City? He was digging a hole or something."

"Driving more than 100 kilometers at the risk of being caught midway?" Liu Jinghui shook his head firmly: "If it is just an idea or a guess, it is not enough for a cautious engineer to make such a decision. If it is not a verified abandoned body If it weren’t for the fact that he had used the solution and found it easy to use, Tan Yong’s most correct choice would have been the construction site in Ningtai County. There is a construction site that Tan Yong is responsible for locally, and it should be more efficient than the construction site in Changyang City where he went to others. It’s convenient and less likely to be exposed.”

This was a very convincing reasoning, and the detective who asked the question had to nod.

"Only with the proven method of abandoning the body, Tan Yong would be unswerving and return to Changyang City directly after the incident, risking being discovered on the road. I suggest that Tan Yong be interrogated immediately and use Ding Lan as a breakthrough point to ask the question His way of abandoning the body." Liu Jinghui said firmly and with full confidence.

Everyone waiting could only listen quietly.

At this time, I heard Yu Wen write: "Then we will interrogate Tan Yong again according to Liu Chu's arrangement. Let him think that he is responsible for the murder. This will make it easier for him to speak. That's what Liu Chu means."

Liu Jinghui said: "That's right. Another thing I think can be asked is what Tan Yong did during the period after kidnapping Ding Lan. Since he decided to increase the crime, why didn't he go back to dispose of the bicycle? Did you forget, or did something else happen? I personally infer that it must have been delayed by something."

"Okay. That's it." The detachment leader agreed, and the matter was settled. The provincial departments also played a significant role.

Liu Jinghui smiled reservedly at everyone, waited for the detachment leader to finish, and then left the small conference room first.

Jiang Yuan watched the shiny big back disappear, then walked out of the conference room to a place with fewer people. He couldn't help but turn to look at Wei Zhenguo and asked, "Is this okay?"

Wei Zhenguo smiled as expected and said, "Isn't it a very powerful feeling?"

Jiang Yuan whispered: "He has no evidence at all!"

Yes, judging from Jiang Yuan's "so many years" of forensic experience, the first thing he noticed was that Liu Jinghui was talking about reasoning, speculation, or inference throughout the meeting. The only thing he didn't say was evidence.

Wei Zhenguo looked around and said, "So, what Liu Chu is most famous for is his reasoning style. He doesn't care about the evidence. He always relies on reasoning to solve the case, and then lets other police officers run for the evidence."

From studying to working, Jiang Yuan's mind was filled with evidence and evidence. Now Liu Jinghui, who was listening to Wei Zhenguo's introduction, was speechless and couldn't help but ask: "Is this okay?"

"Senior police chief of the provincial department, you can solve the case how you want." Wei Zhenguo pulled Jiang Yuan away and emphasized by the way: "The key is that he can solve the case."
