Chapter 269: Taken Down

The group of police officers in the small conference room were like young people participating in an interview, automatically pairing up, automatically combining, automatically electing leaders, and starting to discuss and allocate provinces.

In the end, the two groups actually merged again, starting to focus on the data of their own province, while the other groups were no longer divided by province, but one group was responsible for several provinces.

During this period, Yu Wenshu watched without needing to say an extra word.

Wei Zhengguo and others from the county bureau watched and couldn't help but feel a bit emotional. This kind of working style, which looks like high-level white-collar workers, can only be played by the municipal bureau at the provincial capital level. The criminal police below still prefer traditional models.

"I'll go write the criminal behavior profile." Liu Jinghui was quite familiar with the Changyang Municipal Bureau. Seeing them enter a working state, he turned around to do his own thing.

Not having to go to work, being at ease at home, and having lived for a long time with his wife and children running back to their maternal home, he would also want to return to the workplace and regain the long-lost sense of achievement.

Jiang Yuan had people take out all the physical evidence related to the case and started checking them one by one.

Now that it has been determined that it was done by a person released from prison, if a fingerprint of the murderer can be obtained, the case will be easier to solve.

Most cases are like this, especially in scenes with intense conflict, such as fighting or rape. According to reason, the murderer should have left a large amount of physical evidence.

For example, fingerprints, sperm spots, hair or dandruff, or skin tissue, blood, etc., left by the victim's resistance.

The murderer in this case is relatively special. Perhaps because his physical fitness is not good enough and he is not confident in his control over himself, his starting action was stabbing with a dagger.

Jiang Yuan could tell from the bloodstains at the scene that the murderer came behind the victim and directly stabbed a few times in the back, causing the victim to fall to the ground.

Massive blood loss would cause the victim to lose the ability to resist and fall into a coma or semi-comatose state.

The murderer then proceeded to rape and abuse, and, relatively calmly, wore gloves and a condom.

Even after the matter was finished, he cleaned the places he had bitten, leaving only bite marks, and no usable DNA was extracted.

His calm mentality is both because the person with a criminal record has experience, and also because his mental state is abnormal—

Liu Jinghui's boldness in judging that it was a person with a criminal record was a very bold judgment. Reasonable, but very bold.

If Jiang Yuan were to work on this case independently, he would not first judge it as a criminal record. Perhaps he would check down the two lines of mental abnormality and height. In addition, Jiang Yuan felt that following the point of slippers might also have a breakthrough.

After all, cheap slippers are often made by small factories, and the sales range of small factory products is often not large.

On the other hand, the murderer's economic distress is also a clue. Making a living by crime is actually a very high-difficulty and high-requirement thing. Ordinary murderers can't do it. This guy mostly has to find work and live near the crime scene.

Jiang Yuan was still thinking about how to screen out the murderer when several police officers in the provincial group had already cheered.

Everyone couldn't help but look over, and someone asked, "Did you find the person?"

"Found it!" The person in charge, who was elected by the reorganization, was a capable police officer around 30 years old. After responding, he immediately said, "It's a person from our Shannan Province."

Yu Wenshu and others were originally still feeling emotional, but now they all surrounded him.

The case had major clues, which was indeed exciting, and Yu Wenshu and others were also extremely happy, but this kind of happiness was still vastly different from solving the case.

And he knew very clearly that the so-called finding in front of him really might solve the case.

Thinking of this point, Yu Wenshu, a dignified detachment captain, couldn't help but swallow his saliva.

An old hunter who has hunted many times will swallow his saliva when he sees a sika deer enter the shooting range. An old fisherman who has fished many times will swallow his saliva when he sees a net full of fish, shrimp, and crabs. An old criminal police officer who has worked on many cases will also swallow his saliva when he sees another murderer about to enter the death penalty process.

The elected police officer looked capable. Under the gaze of everyone, he said with a steady voice, "According to big data modeling, we reviewed the list of people released from prison one year before the crime and found a person named Qiao Maishou from Shannan Province who has major suspicion of committing the crime."

He looked at his notebook and said, "Qiao Maishou, from Shannan Province, 27 years old, 25 years old at the time of the crime, height 156 cm. When Qiao Maishou was 13, he was sentenced to three years in a juvenile detention center for robbery and theft. In the center, because he violated prison rules, his sentence was increased by one year. After being released from prison, he was sentenced to 5 years for robbery again. He was 23 when released. After that, he returned to his hometown to live and was detained for 6 months for gathering a crowd to gamble. By the time the crime occurred, he had been released from prison for 8 months."

Liu Jinghui had already stood up while listening, clapped his hands, and said, "Spending his youth in prison, long-term isolation, unable to communicate normally with people... and there are acts of violating prison rules, indicating that he is not adapted to life in prison. In this way, it is easy to lead to personality distortion and character quirks."

He is now not just thinking about catching people; he is more looking forward to his own criminal behavior profile being able to guess the murderer.

The police officer who screened the murderer was also very excited and cooperated by saying: "It is indeed so. Three months after Qiao Maishou was released from prison, he had another conflict with someone and went to the police station. After that, he returned to his hometown to live for a period of time. Two weeks before the crime, he arrived in Changyang City by high-speed rail. Most of the time, he was basically in internet cafes near the crime scene. On July 2nd, he registered and stayed in a small hotel near the train station for a week... On July 10th, he returned to his hometown to live. Currently, he is serving a sentence in Yunchang City Prison for theft..."

With current criminal investigation methods, wanting to obtain a person's trajectory is very simple. Basically, as long as you know the ID number, you can know the means of transportation you took and the place where you stayed.

Qiao Maishou perhaps didn't understand these, or didn't pay too much attention, leaving traces everywhere. However, it is not easy for a person to really want to pay attention not to leave traces.

The fact is, when there were no clues involving Qiao Maishou, it didn't matter if he left these trajectories. However, once his existence was discovered, almost all the evidence was pointing to him.

Yu Wenshu no longer doubted and laughed heartily: "Alright, the steps of arrest are saved. Tang Jia, you organize the materials, and hurry up and enter the process here..."

Tang Jia immediately responded.

Yu Wenshu looked at Jiang Yuan and Liu Jinghui again.

If he had to say, he was relatively familiar with Liu Jinghui and had often invited Liu Jinghui to take action before.

However, most of the time, his demand for Liu Jinghui was of a consultative nature, that is, asking Liu Jinghui to put forward some suggestions and guide some directions for solving the case.

Most of the provincial police chiefs also prefer this way of cooperation, which is easy for themselves and easy for the local area.

At that time, Yu Wenshu only used Liu Jinghui as a general senior police chief.

But this time, the effect produced by the cooperation between Liu Jinghui and Jiang Yuan was too far beyond Yu Wenshu's expectations.

Not exaggerating, it was beyond everyone's expectations.

"Then, this case is considered passed?" Liu Jinghui pushed the file.

Yu Wenshu said "En" and smiled: "No wonder this case was given a high score by you two. Next..."

"So hungry." Liu Jinghui rubbed his stomach and stood up.

"Eat first, eat first." Yu Wenshu was as enthusiastic as if he were greeting a master to play. ===== CHAPTER 270 =====

"Eat first, eat first," Yu Wenshu said, his enthusiasm like that of a host welcoming a guest to have a good time.
