After lunch...

Wei Zhenguo and his team arrived at the Criminal Investigation Division of Changyang City.

The Criminal Investigation Division of Changyang City was a large unit, with multiple criminal investigation teams under its jurisdiction, just like the criminal investigation team in Ningtai County. Its Criminal Science and Technology Center was also of a large team size, with the largest laboratory scale and the most types of equipment. In terms of quantity alone, it was several times that of the Provincial Department.

At the same time, the Criminal Investigation Division of Changyang City also had its own office building, a 12-story building that naturally had the flavor of a small local police station that could not be reached.

Inside the building...

In a small conference room.

The air conditioner was whirring and protesting that there were too many people in the room.

The chairs, which had been temporarily moved in, were haphazardly piled up, occupying the space. Even the hanging plants on the window sill had been moved aside, leaving only a few leaves scattered on the ground, helpless like a few little lobsters being cleaned.

At this time, more than ten criminal investigators were seated, the most conspicuous of whom was the one sitting near the door. He had a big back-combed hairstyle, and his hair was dark and shiny, like two bars of three stars.

When everyone came in and saw him, they would all shake with awe, feeling that this person was extraordinary - at this level at this age, he was indeed very extraordinary.

Jiang Yuan came in and couldn't help but wander his eyes over the man's big back-combed hairstyle and shirt.

Most of the other criminal investigators had short hair that was easy to manage, and their shirts were messy and a bit dirty. But this man had a meticulous hairstyle and a clean, spotless shirt, like a hairless cat among a group of long-haired cats, feeling a bit strange.

"Everyone is here, let me introduce you. This is Liu Jinghui, a fourth-level senior police officer of our Provincial Criminal Investigation Bureau, and Gao Qiang, a third-level senior police officer of our bureau." Yu Wenshu, the head of the Criminal Investigation Division, who was sitting inside, began to introduce them as soon as Jiang Yuan and his team arrived.

Liu Jinghui was the young hairless cat with the big back-combed hairstyle. He stood up politely and nodded to everyone.

Gao Qiang, the chief of the department next to him, was just an ordinary man in his forties, with dirty clothes and no personality.

Yu Wenshu then introduced Wei Zhenguo and Jiang Yuan and the others.

Wei Zhenguo stood up sociably, apologized to everyone, and said, "I may have been a little slow due to unfamiliar road conditions, and kept you all waiting."

"It's okay, we came early." Yu Wenshu ended the topic with one sentence, and then began to introduce the criminal investigators of his own team.

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

In the police system, the Provincial Department, the Municipal Bureau, and the County Bureau are not subordinate to each other, but only have a relationship of business guidance. This is similar to institutions such as the Agricultural Department, the Finance Department, or the Education Bureau.

The County Education Bureau must follow 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 Municipal Government, and they are not subordinate to each other.Similarly, in terms of personnel power, the criminal investigation brigade of the county bureau also listened to the county bureau and county government, and their operations were independent of the criminal investigation support team of the municipal bureau. The criminal investigation support team of the municipal bureau had its own criminal investigation brigade and could only command its own criminal investigation brigade. When it came to the county bureau, it could only supervise or guide the operations.

At the provincial criminal investigation bureau or criminal investigation corps, the nature of their work did not change much, only with fewer operational components. Most of the provincial criminal investigation bureaus did not handle cases themselves, and the criminal investigation bureau was just an ordinary department within the provincial bureau.

However, the internal personnel of the provincial criminal investigation bureau were not all experts and masters, but those who could be sent out to supervise cases were definitely not simple.

The participation of the provincial criminal investigation bureau also accumulated the excitement of the detectives present.

"Next, I will read the relevant documents about the missing case 326, now called the 326 kidnapping and murder case, and the arrangement of the reorganized special task force...I will serve as the leader of the task force, and the deputy leaders are Liu Jinghui and Gao Qiang..." Yu Wenshu's responsibilities in the municipal bureau were equivalent to Huang Qiangming's responsibilities in the county bureau, just on a larger platform.

Wei Zhenguo, the deputy captain of the sixth squadron of the criminal investigation brigade of the Ningtai County Bureau, and Jiang Yuan and others had no chance to show their abilities at the meeting presided over by Yu Wenshu, and only listened to him reading documents and giving speeches.

After nearly 10 minutes, Yu Wenshu brought the topic back: "According to expert analysis, it is initially believed that Tan Yong, the main suspect in the 326 kidnapping and murder case, was involved in more than one murder case."

Woo woo woo.

The sound came from the electric fan.

A quick look at tinyurl.com/2p9emv8w will leave you more fulfilled.

Everyone was very calm.

Seeing the people from the provincial bureau, it was like digging out a man wearing your clothes from the wardrobe in your bedroom. He couldn't possibly be here to fix the air conditioner.

Similarly, if only one person died in the case of Tan Yong, it would be redundant for the provincial bureau to send two people.

"Liu, you go ahead and speak." Yu Wenshu gave up his position.

"I'll just say it here." Liu Jinghui stood up and said, "There are several doubts in the 326 murder case. Firstly, the main suspect Tan Yong claimed that he kidnapped Ding Lan because he failed to confess his love to her, and out of anger, he impulsively acted to scare her by throwing her beside the highway. Then, he impulsively developed to rape and planned to take Ding Lan back to his own house to kill and bury her. However, due to Ding Lan's begging, he dug a basement to imprison her."

Liu Jinghui scanned around with sharp eyes and said slowly, "The most unreasonable part here is that Tan Yong brought Ding Lan back to Changyang City. From Ningtai to Changyang City, they had to pass through toll stations and inspections. It is not rational to take such a big risk just to take Ding Lan back to his vacant house to kill and bury her. Tan Yong must have concealed something crucial during his confession."Liu Jinghui looked at the reactions of the surrounding detectives and continued, "Tan Yong works in construction and knows how to use construction vehicles. He has familiar construction sites and many options for abandoning bodies. He claimed to be digging a basement to bury bodies, but only decided to switch from burying to digging because of Ding Lan's begging and active service... Is it necessary to do this? Is the difficulty and risk greater than burying bodies in the wilderness or construction sites? Especially since digging a basement requires some machinery, it's not easy for Tan Yong to transport it here."

"Furthermore, Tan Yong has committed at least four crimes, including the female corpse we dug up from the basement, who was also a prostitute. The following three times he kidnapped and sold prostitutes, he left little evidence, proving that his thinking is more meticulous. Why would such a person leave fingerprint evidence on Ding Lan's bicycle?"

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

"What's your inference, Chief Liu?" Yu Wenshu knew that Liu Jinghui liked to reason and had proven his strength in the criminal investigation bureau through multiple reasoning, so he didn't challenge his "authority".

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

"You go on," Yu Wenshu cooperated.

Liu Jinghui nodded in satisfaction and said, "First, leaving fingerprints shows that Tan Yong's kidnapping of Ding Lan was likely impulsive, but not a random crime. Choosing Ding Lan as the target for kidnapping was not convenient for selling prostitutes. He could have randomly chosen a target in the provincial capital to complete his crime."

Liu Jinghui paused for a moment and continued, "At the same time, as the first female prisoner in the basement, Ding Lan's special status can also explain why he changed from burying to digging and imprisoning."

Some people nodded in agreement, but most of them remained calm. Liu Jinghui's reasoning was only ordinary, and many people present could do it. However, most of them did not dare to publicly speak out so confidently.

Liu Jinghui enjoyed squinting his eyes, and his favorite part of reasoning was the power that erupted from calmness.

After briefly describing the case, Liu Jinghui finally said the word he had been holding onto for a long time: "But! None of these answers can explain why Tan Yong came back to Changyang City!"

Liu Jinghui suddenly raised his voice, attracting everyone's attention.

Several detectives frowned and began to think.

"Indeed, he could have abandoned the body on the spot, gone to his familiar construction site, or even to other counties and cities, but he shouldn't have come back to Changyang City." A detective from the Changyang City Criminal Investigation Brigade pondered and said, "He's someone who often travels outside, so he should have seen and experienced road inspections in the provincial capital.""That's right. Tan Yong's company is a construction company under the Road and Bridge Group, with business all over the province, building various roads, including highways, national roads, toll stations, and inspection stations... So, he must have a very strong reason for choosing Changyang City." Liu Jinghui stated his reasoning and said, "I believe that Tan Yong has a familiar and verified method of disposing of bodies."

The detective who spoke earlier asked, "Perhaps he just happened to think that a certain construction site in Changyang City was suitable? Maybe they were digging a pit or something."

"Risking being caught halfway and driving over 100 kilometers?" Liu Jinghui shook his head firmly. "If it was just an idea or a guess, it would not be enough to make a cautious engineer like Tan Yong make such a decision. If it's not a verified method of disposing of bodies, and if he hasn't used it before and found it effective, Tan Yong's most correct choice should be the construction site in Ningtai County. There is a construction site there that Tan Yong is responsible for, which should be more convenient and less likely to be exposed than going to a construction site in Changyang City that is managed by someone else."

This was a very convincing reasoning, and even the questioning detective had to nod in agreement.

"Only with a verified method of disposing of bodies will Tan Yong be determined to return to Changyang City after the crime, risking the risk of being discovered on the road. I suggest that we immediately interrogate Tan Yong, using Ding Lan as a breakthrough point, and ask him about his method of disposing of bodies." Liu Jinghui spoke with conviction and confidence.

Everyone could only listen quietly.

At this moment, Yu Wenshu said, "Then let's follow Liu's arrangement and interrogate Tan Yong again. Let him think that he is carrying a murder case, which will make it easier for him to confess. Liu, is that what you mean?"

Liu Jinghui nodded. "Yes. In addition, I think we can also ask Tan Yong what he did during the time after he kidnapped Ding Lan. Since he decided to escalate the crime, why didn't he go back to dispose of the bicycle? Did he forget, or did something else happen? I personally speculate that he was delayed by something."

"Okay, let's do that." The captain made a decision, and the provincial department played a significant role.

Liu Jinghui smiled modestly at everyone and left the small conference room first after the captain finished.

Jiang Yuan watched the shiny bald head disappear and walked out of the conference room. When they were in a less crowded place, he couldn't help but turn around and ask Wei Zhenguo, "Is this really okay?"

Wei Zhenguo smiled as expected and said, "Doesn't it feel very powerful?"

Jiang Yuan whispered, "He doesn't have any evidence at all!"

Yes, based on Jiang Yuan's "many years" of forensic experience, he first noticed that during the entire meeting, Liu Jinghui was talking about reasoning, speculation, or inference, but never mentioned evidence.

Wei Zhenguo looked around and said, "That's why Liu has the most famous reasoning style. He doesn't care about evidence, he always relies on reasoning to solve the case, and then lets other police officers gather evidence."Jiang Yuan has been thinking about evidence since he was studying to now working as a forensic doctor. Now, hearing Wei Zhenguo's introduction of Liu Jinghui, he is speechless and asks, "Can it be done like this?"

"As a senior police officer in the Provincial Department, they can solve the case however they want." Wei Zhenguo pulls Jiang Yuan away and emphasizes, "The key is they can solve the case."
