Chapter 854

"Team Leader Jiang, how many cars are we going to take?" Wang Chuanxing came to ask Jiang Yuan to arrange.

Jiang Yuan naturally looked at Huang Qiangmin.

Huang Qiangmin looked at Bai Jian and said: "Shi Tingxian has no money. Our trip is basically poverty alleviation. You can take as many cars as you want."

The silence of Bureau Chief Bai Jian echoed in the sky.

What he said just now was quite good, but as everyone knows, the woodpecker's beak cannot peck out money, and Bureau Chief Bai has already used a tongue that can wrap around the skull to lick Jiang Yuan.

"Let's take three cars first. The rest of the people do things as usual. If necessary, reinforce them." Jiang Yuan is now used to taking a large number of people with him when he goes out.

Bai Jian smiled and said: "Actually, ordinary criminal investigation personnel, we are still sufficient. It is just that we are indeed lacking in criminal science."

"Samples can be sent to Ningtai County for inspection. If necessary, send them to Changyang City." Jiang Yuan no longer needs to consider the expenditure of funds. He only cares about how to do it conveniently, or how to be efficient and accurate. The rest, naturally, has Huang Qiangmin to settle for him.

Since the completion of the comprehensive building in Ningtai County, the Criminal Science and Technology Squadron of Ningtai County Bureau has begun to expand. Various laboratories have also begun to be equipped—the bureau's laboratory does not have any high-end appearance. It is just a few experimental tables, some equipment and instruments can be opened. The laboratory with better equipment is equipped with a few instruments and a computer, which is considered high-end.

However, such a laboratory is enough for ordinary cases, and general inspection tasks can be completed.

Without waiting for Huang Qiangmin to speak, Bai Jian responded happily.

Huang Qiangmin smiled. He is not the kind of character who must report, nor is he worried about what will happen if one or two prey pass through his territory and escape. He will only solve all problems in a necessary moment, a death roll, recover all costs in lurking, and gather enough food for the whole family.

Bai Jian hurriedly printed the relevant information of the case, especially the photos, for Jiang Yuan.

"What conclusion does your investigation have?" Jiang Yuan asked while looking at the photos. Shi Tingxian's investigation has actually been going on for almost 5 days. For criminal cases now, especially homicide cases, most of them have been solved. Even if they are not solved, the wrong investigation direction is also useful information.

Bai Jian organized his thoughts and said: "We first considered the possibility of love killing, because peeling the face has a tendency to commit crimes by acquaintances."

"In this piece of acquaintance crime, we assigned a criminal police squadron to be responsible, visited the surrounding masses and the victim's relatives and friends, and used technical investigation means to investigate the victim's communication tools such as telephone, WeChat, and QQ, and did not find clear information about cheating."

"Of course, we also considered normal acquaintance crime, that is, mainly to cover up or destroy the face. Peeling the face and even the scalp, such an operation is too cruel and special. It is probably difficult for ordinary people to carry it out. So, we also screened acquaintances for this reason, expanded the scope, and considered that the murderer might be engaged in slaughter, medicine, funeral, forensic medicine, military police and other occupations that may come into contact with corpses daily, and there was no harvest."

Bai Jian looked at Jiang Yuan as he said this and said: "In this piece of stranger crime, we mainly hope to seek breakthroughs through technical means. At the crime scene, the victim had traces of dragging and traces of fighting, but the murderer also cleaned up the scene to a certain extent. The most troublesome point is that at the crime scene, many villagers entered to watch at that time, took photos and videos, and there were children or others who took advantage of the chaos to pick up items in the small shop. The village organized personnel to drive them away, which caused some conflicts..."

Jiang Yuan's eyelids jumped, and he didn't say anything.

The senior police chiefs around felt funny, or were just aroused to share.

Fake crime scene: Inside the bright yellow cordon, the on-site investigation personnel in white coats stepped on the acrylic board, taking fingerprints inch by inch, recording every detail seriously, wishing to move the entire crime scene with walls and houses to the laboratory to check with microscopes and beakers.

Real crime scene: Inside the old, crooked cordon, villagers broke in without any scruples, politely served water to the police officers, asked how the bad things they heard about themselves and their children and relatives and friends could be handled, and after being popularized, while honestly apologizing, while rinsing their mouths with tea, and spitting on the ground of the crime scene on the spot. At the same time, the criminal police scolded while roughly taking photos of the scene in the house, then took a few fingerprints and footprints in relatively obvious positions, and stuffed the ordinary involved items into plastic bags, only putting important physical evidence into evidence bags and numbering them, but one evidence bag often has multiple cotton swabs and debris.

Therefore, things like irrelevant villagers making a scene at the crime scene sound outrageous, but no police squadron leader raised doubts.

Actually, it is still quite outrageous. Over the years, a police team may only encounter one or two such homicide scenes, so it seems more credible.

"The victim's death was so miserable, do the villagers still want to watch and take photos?" Wang Chuanxing was still young. When he made records, he felt it was not very reasonable.

Bai Jian said calmly: "Someone vomited, so they vomited at the crime scene. We took DNA. But the more people who feel disgusted, the more people want to challenge it. After our police arrived, some people climbed over the wall..."

"Then the traces on the wall were also destroyed?"

"Also taken." Bai Jian paused and said: "At the scene, there is now protection."

The case sharing reached here, and some people around were shaking their heads.

Although Bai Jian didn't say it clearly, everyone is a police team manager at the same level, and they can guess some of Bai Jian's thoughts.

For example, he said that he first considered love killing and acquaintance killing. Why consider it this way? Isn't it because only then is there a probability of successful detection. If it is not acquaintance crime, not passion killing, not love killing, but stranger crime, then this case is highly likely to be one of the serial killings.

Bai Jian didn't want to verify this possibility, because it was useless to verify it. Shi Tingxian did not have such resources and ability to face such cases. Not to mention anything else, just the most basic pursuit package: prepare 12 or 13 people for half a squadron, send three or four people to fly wherever there is a clue, accommodation and meal subsidies are given according to standards, rent a car locally, treat local police comrades to a meal from time to time, and bring back a suspect on average every week... In less than three months, the county bureau should stop paying wages.

If he couldn't invite Jiang Yuan, if he encountered the latter situation, Bai Jian could only ask for help from the Qinghe City Bureau and the provincial department.

Bai Jian looked at Jiang Yuan with eager eyes.

Jiang Yuan examined the photos of the victim for a long time, looking at the white teeth and roots of the deceased exposed outside, as well as the skull exposed halfway, and said: "The scalp and face were peeled off very messily, and it can't be called any technicality. From this point, professional personnel should be excluded. Otherwise, if you want to peel the scalp normally, cut from here..."

Jiang Yuan gestured twice, took his hand back, and said: "The victim's cause of death is mechanical asphyxia. The murderer should have used some kind of rope. The rope was not found? I see that fiber was taken?"

"Yes, sent to Changyang City for analysis." Bai Jian said: "At present, it matches a rope sold in the small shop."

"Blunt force injury on the head... The one used should be a wooden stick, right? Did you find a matching one?" Jiang Yuan's tool trace identification is also LV6, and he gives a conclusion directly by looking at the photos.

Bai Jian was stunned for a moment and said softly: "What kind of wooden stick is it?"

A person is injured, or dies, what is the tool that caused his death, the difficulty of this identification is still relatively high. At the very least, the forensic doctor in Shi Tingxian failed to complete it smoothly.

Jiang Yuan took a photo and placed it on the table, and took another photo of the scene, and said directly: "Judging from the diameter and strength of the wooden stick, I tend to be the top door stick used for the top door. Look at this position of the victim's main door. It should be placed with a top door stick daily. If the crime scene is not found, you have to visit and ask, and then look around. Such a thick wooden stick should not be easy to handle."

"Good, good." Bai Jian nodded hurriedly, his heart settled a lot.

To say, Jiang Yuan's way of solving the case and Bai Jian's are actually similar. Everyone uses their own strengths and advantages to try to make a breakthrough in the facts of the case, but everyone's strength is different.

"Team Leader Jiang, the motorcade is ready, are we going to the scene?" Wang Chuanxing came to report.

"Let's go. Take two more cars, it's easy to find things." Jiang Yuan said.
