Chapter 350 The Same Trace
"Contacted the policeman who handled the case that day." Wang Chuanxing came over with his mobile phone, paused, and said, "Because it is an attempted case, the progress of this case is relatively slow, and it has basically not progressed."

"Let them send a copy of the photos and the like, and I will sort them out right away."

"The victim's family has been contacted."

The subordinates came to report one by one. At this time, Jiang Yuan raised his head and said, "I have a chat with the victim's family, who is it?"

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

Jiang Yuan said "En", got the phone, waited for two seconds, and said in a deep voice: "Hello, I'm Jiang Yuan, are you Xue Zhou's mother?"

"Well, it's me, what's the matter?" The woman on the other end of the phone was very nervous.

"We just know some things... Can you tell me more about Xue Zhou's abduction? What kind of person is the criminal?"

"It's a middle-aged woman in her 50s. She should be in good condition. My son said her skin is pretty good and fairer..."

Under Jiang Yuan's guidance, Xue Zhou's mother described the criminal's situation, and then said nervously: "She won't look for us again? Since that incident in our home Zhouzhou, we have never dared to go to a lively place. place, several times, when there was no one in the room, he began to cry..."

Jiang Yuan tried his best to comfort him, and then handed it over to Tang Jia, and let her continue to comfort him.

Criminal cases are just work tasks for the police. Although they are complicated and heavy, they are not painful after all.

For victims and their families, even an attempted case can be a source of terror for years.

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

The 8 people he brought with him immediately looked at them attentively.

Several other experts, as well as the criminal police of the Guqi City Criminal Police Team, also pricked up their ears.

"Two people went to the scene to have a look. The place is a rural market with a lot of people, and the possibility of leaving traces is relatively small, but the rural market is relatively remote. The criminal chose this place. Is it related to her personal experience? Local people, or have relatives here? You can ask carefully."

Jiang Yuan didn't name anyone, this is also a small tradition that has gradually formed since the establishment of Jiang Yuan's special class for accumulated cases.At the beginning, Jiang Yuan didn't know who was good at what, and he didn't even remember all the names.

After the police officers self-managed for a period of time, the effect was good.In fact, they are all very mature criminal police officers. Their IQ and experience are all on the line. If you put them outside, it’s not a problem to command a squadron. 8 people will automatically assign tasks. For this kind of group discussion level, look at each other. That's it.

Shen Yaowei and Meng Chengbiao looked at each other and said, "Let's go over."

Both of them know how to communicate. Although Meng Chengbiao's communication method is a bit hard-core, they are both useful.

Jiang Yuan nodded, and said: "Sending you to the scene, in addition to paying attention to the scene, the focus is to find witnesses, and whether there is surveillance, their means of transportation, whether they need accommodation, whether there is accommodation..."

Jiang Yuan first said what he thought of, and then said: "If the attempted case was not solved at that time, the clues they can leave now are limited. You mainly rely on yourself."

"Yes." Both Meng Chengbiao and Shen Yaowei agreed.

Without waiting for Jiang Yuan to give another order, Wang Chuanxing took the initiative to say: "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 children. , A lot of people posted on Moments and Weibo, I sorted it out and brought it over.”

"Okay." Jiang Yuan nodded.

The other two took the task of contacting the Internet police and viewing surveillance video.

Jiang Yuan didn't continue to allocate, and took the existing photos and started to open them.

Use old cases to solve new cases, and the most used cases are serial killers.

The reasoning is actually the same. Because serial killers have killed more times, they have more experience summed up. They can often choose the most difficult posture to commit crimes and dispose of corpses.

In this case, if you can find the first case of the serial killer and concentrate on the first case, there is a high probability of detection.

It's like a student who has worked hard to become a top student, and his test papers are impeccable, and the teacher can't deduct a single point. What should we do?Find out the test papers he made earlier, and determine the affiliation of the previous papers based on some of his answer characteristics, and then deduct 41 points from the previous papers in one go. Wouldn't it be great?

The principle is such a principle, but it is not easy to do it.

It is very rare to prove that the two cases were done by the same person or the same group of people, so that the two cases can be handled together.

At least, for an ordinary criminal police team of the city bureau, it would be out of breath to achieve this step.

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

Including the attempted abduction case in Daji in the countryside, if the case can be solved in the blink of an eye, even if the local police are very busy, they will line up and finish it.

Or because there is a certain degree of difficulty, I did not continue to do it.

And this difficulty is itself an obstacle.

For example, Jiang Yuan, who wants to solve this attempted case immediately, is still a bit at a loss.

Regardless of the size of the backlog, there is actually a certain degree of difficulty in detection.

In particular, the police do not pay attention to the current case. If the file is not well organized, it will be more difficult to solve the case with the backlog.

Jiang Yuan's mood is stable.At the Wenxiang Police Station, he was able to follow the order of the accumulated cases. Now that he is here, he still has enough confidence, but it takes some time to accumulate and screen information.

The conference room entered a brief silence.

Those who should go out go out, those who should do things do things.

hum.

Jiang Yuan's cell phone vibrated.

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

"Oh, Team Jiang, I'm Wei Yin. Let me tell you about the 326 kidnapping and murder case you solved earlier. The principal culprit, Tan Yong, was executed this morning." Jiang Yuan.

Jiang Yuan froze for a moment, then nodded and said: "Good execution."

"We also said that when this kind of person sparks, he will turn black fire... The victim and his family members should have received the news, and someone sent a pennant over, and the Yellow Bureau asked him to hang on the fourth floor." Wei Yin said two more words Just hang up the phone.

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

It's just that in the eyes of everyone, Jiang Yuan, who had just been turned into a corpse, seemed to be shining.

evening.

A large amount of information began to gather.

Not only Jiang Yuan, but two other experts also joined in quietly.One is Wu Xia, who is doing fingerprints, and the other is Professor Liu, who is doing crime scene reconstruction. They have nothing to do now, and they are unwilling to rest, and they also start to study the case of Daji in the countryside.

At this time, a witness's description caught Jiang Yuan's attention.

He quickly turned on the computer and searched.

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

Hearing his tone, everyone looked over.

"In the case of Daji in the countryside, some people said that they saw the criminal get into a red car and leave. I noticed that a red Santana was missing in the police report, and then I checked the case in Guqi City. Tian lost his car too." Jiang Yuan tapped the screen, Tang Jia quickly came over and connected his screen to the projection.

Everyone took a look at the situation and said humanely: "Although there are relatively few cases of car loss now, there are still people who steal cars for various reasons. Car thefts have all occurred, and it is not certain that the two cases are related. Yes."

"One reason is that the car was stolen by Daji in the countryside, and it was quickly discarded, leaving many traces in the car. In Guqi City, after I found out that a car rental company's car was maliciously discarded beside the national road, The traces in the photos are similar to those filed by the car rental company." Jiang Yuan used the LV6 traces to identify and compare the two cars, so he was naturally extremely sure.

Wu Xia, who is also an expert in trace identification, was excited when he heard it, and hurriedly asked, "What trace?"

Jiang Yuan then showed some photos to Wu Xia.

Wu Xia: That's it?
