Chapter 340: Same Traces

"Contacted the police officer who handled the case that day." Wang Chuanxing came over with his phone, paused, and said: "Because it was an attempted case, the progress of this case was relatively slow, and it basically didn't move forward."

"They sent a copy of photos and such over. I will organize them immediately."

"Contacted the victim's family."

The subordinates came over to report one by one. By this time, Jiang Yuan raised his head and said: "I'll chat with the victim's family for a few words. Who is it?"

"The victim's mother." Tang Jia dialed the phone and handed the phone directly to Jiang Yuan.

Jiang Yuan let out an "En," took the phone, waited for two seconds, and said in a deep voice: "Hello, I am Jiang Yuan. Are you Xue Zhou's mother?"

"En, it's me. Is there anything?" The woman on the other end of the phone was very nervous.

"We are just understanding some situations... Can you describe the situation when Xue Zhou was abducted in detail? What kind of person was the perpetrator?"

"It was a middle-aged woman in her forties or fifties. She should have been maintained quite well. My son said her skin was quite good, relatively white..."

Under Jiang Yuan's guidance, Xue Zhou's mother described the perpetrator's situation, and then nervously said: "Will she come to find us again? Since that time, we haven't dared to go to lively places again. Several times, when there was no one in the room, he would cry..."

Jiang Yuan comforted her as much as possible, then handed it to Tang Jia, letting her continue to comfort her.

Criminal cases are just work tasks for the police. Although complex and heavy, they are not, after all, a pain of the flesh.

And for the victims and their families, even an attempted case can cause panic and unease for many years.

Jiang Yuan shook his head, returned to the conference table, pondered for a moment, and said: "Let's decompose the tasks."

The 8 people he brought gathered their attention and looked over.

The other several experts, as well as the criminal police from the Guqi Municipal Police Team, also pricked up their ears.

"Two people go to the scene to take a look. The local area is a rural fair, and the flow of people is very large. The possibility of leaving traces is relatively small, but the rural fair is relatively remote. The perpetrator chose this place. Is it related to her personal experience? Is she a local, or are there relatives here? You guys ask around carefully."

Jiang Yuan didn't name anyone. This is also a small tradition that has gradually formed since Jiang Yuan's cold case special class was established. At the beginning, Jiang Yuan didn't know who was good at what, and didn't even remember all the names.

After the police officers managed themselves for a period of time, the effect was quite good. In fact, they were all very mature criminal police. Their IQ and experience were all online. If they were put outside, commanding a squadron or something would not be a problem. The 8 people automatically allocated tasks. This kind of small group discussion level thing was settled by looking at each other.

Shen Yaowei and Meng Chengbiao looked at each other and said: "Let the two of us go."

Both of them were relatively good at socializing, although Meng Chengbiao's socializing method was a bit hardcore, but it was all useful.

Jiang Yuan nodded and said: "Sending you to the scene, besides paying attention to the scene, the focus is on finding eyewitnesses. Also, is there surveillance? Their transportation, do they need accommodation? Is there accommodation..."

Jiang Yuan said the things he thought of first, and then said: "Attempted case, if it wasn't solved at the time, the clues they can leave now are also limited. You guys mainly rely on yourselves."

"Yes." Meng Chengbiao and Shen Yaowei both responded.

Without waiting for Jiang Yuan to continue allocating, Wang Chuanxing took the initiative and said: "According to the time and place they provided, I found some photos on social media. Because many people in the rural fair know each other, and it is a case of losing a child, quite a few people posted on places like Moments and Weibo. I have organized them and will bring them over."

"Good." Jiang Yuan nodded.

The other two took the tasks of contacting the network police and watching surveillance images.

Jiang Yuan didn't continue to allocate, took the existing photos, and began to flip through them.

Through old cases to solve new cases, the most used is the case of serial killers.

The truth is actually the same. Because serial killers kill many times, the experience summarized is also more, and they can often choose the posture that is least likely to be discovered to commit crimes and dispose of bodies.

In this situation, if one can find the first case done by a serial killer and concentrate all efforts on the first case, there is a high probability of solving it.

This is like a student who worked hard to become a top student and made an exam paper that was flawless. What should the teacher do? Find the exam papers he did earlier, determine the ownership relationship of the previous papers based on some of his answering characteristics, and then deduct 41 points from the previous papers in one breath. Isn't that refreshing?

The principle is just this principle, but doing it, the difficulty is actually not small.

Proving that two cases were done by the same person or the same group of people, thereby combining the two cases for processing, is itself quite difficult.

At least, for an ordinary criminal police team of a municipal bureau, doing this step is already panting.

On the other hand, relatively simple cases are only relative.

Including this attempted abduction case at the rural fair, if it were a case that could be done by blinking, the local police, even if they were very busy, would have solved it in line.

It is still because there is a certain difficulty that it was not continued.

And this difficulty itself is also an obstacle.

Like Jiang Yuan, now wanting to immediately solve this attempted case, it is still a bit impossible to start.

Cold cases, regardless of size, actually have a certain difficulty in solving.

Especially if the police of the current case don't pay attention, and the case files are not organized well, it is even more difficult to solve it as a cold case later.

Jiang Yuan's mood was stable. In the Wen Township Police Station, he could do cold cases in order. When he came here, he still had sufficient self-confidence, but it just needed some time to accumulate information and filter information.

The conference room entered a short calm.

Those who should go out went out, and those who should do things did things.

Buzz.

Jiang Yuan's phone vibrated.

Jiang Yuan directly pressed the hands-free mode and said: "I have turned on hands-free."

"Oh, Team Leader Jiang, I am Wei Yin. Reporting to you, the 326 kidnapping and murder case you solved before, the main culprit Tan Yong was executed this morning." Wei Yin was the internal affairs of the detachment, and also relayed it to Jiang Yuan after receiving the news.

Jiang Yuan was stunned for a moment, then nodded and said: "Executed well."

"We also said, this kind of person will emit black fire when cremated... The victim and family should also have received the news. Someone even sent a banner over. Director Huang had it hung on the fourth floor." Wei Yin said two more sentences before hanging up the phone.

Jiang Yuan ended the call and continued to work at the desk.

Only in the eyes of everyone, Jiang Yuan, who had just caused someone to become a corpse, seemed to be emitting light.

Evening.

A large amount of information began to converge.

Not only Jiang Yuan, but two other experts also joined in silently. One was Wu Xia who did fingerprints, and one was Professor Liu who did crime scene reconstruction. They had nothing to do now, and were not willing to rest, so they also began to study the rural fair case.

At this time, the description of an eyewitness caught Jiang Yuan's attention.

He quickly opened the computer and searched.

After several checks, Jiang Yuan let out a long breath: "These guys, they have the habit of stealing cars."

Listening to his tone, everyone looked over.

"In the rural fair case, someone said they saw the perpetrator get into a red car and leave. I noticed that in the police report, there was a red Santana lost, and then I checked the case in Guqi City. A car was also lost these days. The traces in the photos are similar to the traces in the photos of the rental company's car that was maliciously abandoned on the national highway." Jiang Yuan used his LV6 trace identification to match the two cars, naturally incomparably certain.

Wu Xia, who was also a trace identification expert, became excited as soon as he heard it and hurriedly asked: "What traces?"

Jiang Yuan then showed several photos to Wu Xia.

Wu Xia: Just this? ===== CHAPTER 341 =====

Jiang Yuan then showed several photos to Wu Xia.

Wu Xia: Just this?
