National Forensic Doctor

"Captain Jiang, how many cars are we going to take?" Wang Chuanxing came over and asked Jiang Yuan to facilitate arrangements.

Jiang Yuan naturally looked at Huang Qiangmin.

Huang Qiangmin glanced at Bai Jian and said: "There is not much money in Shiting County. Our trip there is basically for poverty alleviation. We can take as many cars as you like."

Director Bai Jianbai's silence echoed through the sky.

What he just said is very good, but as we all know, a woodpecker's beak cannot produce money, and Director Bai has already licked Jiang Yuan with his tongue that can go around the skull.

"Let's go to three cars first, and the rest of the people will continue to do things as usual. If necessary, we will provide reinforcements." Jiang Yuan is now used to taking a large number of people with him when he goes out.

Only then did Bai Jian chuckle and said: "Actually, we are still sufficient for ordinary criminal investigators, but we are indeed lacking in criminal science."

"The samples can be sent to Ningtai County for testing, and then to Changyang City if necessary." Jiang Yuan no longer has to consider the issue of expenses. He only cares about how to make things convenient, or in other words, how to be efficient and accurate. Gao, naturally Huang Qiangmin would take care of the rest for him.

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

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

Before Huang Qiangmin could speak, Bai Jian happily agreed.

Huang Qiangmin also smiled. He is not the kind of character who must retaliate, and he is not worried about what will happen if one or two prey pass by his territory and escape. He will only solve all problems with a death roll at the necessary moment and take back All the costs of lurking and collecting enough food for the whole family.

Bai Jian quickly printed out the relevant information about the case, especially the photos, and gave them to Jiang Yuan.

"Do you have any conclusions from your investigation?" Jiang Yuan asked while looking at the photos. The investigation in Shiting County has actually been carried out for almost 5 days. After such a long period of investigation, most of the current criminal investigation cases, especially murder cases, can be solved. Even if they are not solved, the wrong investigation Directions are also useful information.

Bai Jian organized his thoughts and said: "We first considered the possibility of love killing, because there is still a tendency for acquaintances to commit the crime."

"We assigned a squadron of criminal police to take charge of the crime committed by an acquaintance. We visited the surrounding people and the deceased's relatives and friends, and used technical investigation methods to investigate the deceased's phone, WeChat, QQ and other communication tools. No clear evidence was found. of cheating."

"Of course, we also consider that normal acquaintances commit crimes, that is, they mainly cover or destroy the face, peeling off the face and even the scalp. Such operations are too cruel and special, and it may be difficult for ordinary people to carry out it. Therefore, we are also Therefore, we did a certain screening of acquaintances, expanded the scope, and considered that the murderer may be engaged in occupations such as slaughtering, medicine, funerals, forensics, and military police that may come into contact with corpses on a daily basis, but there was no gain.”

When Bai Jian said this, he looked at Jiang Yuan and said: "We mainly hope to seek breakthroughs in technical means when it comes to strangers committing crimes. At the crime scene, there were traces of dragging the deceased and signs of fighting, but the murderer had no control over the scene. A certain degree of cleaning was also carried out. The most troublesome thing was the scene of the crime. At that time, many villagers came to watch, took photos and videos, and some children or others took advantage of the chaos to pick up items from the small shop. The village organized personnel The evictions were carried out and some conflicts were caused..."

Jiang Yuan's eyelids twitched, but he didn't say anything.

Some of the senior police chiefs surrounding him found it funny, while others were just aroused to share.

Fake crime scene: Within the bright yellow blockade, on-site investigators in white coats stepped on the acrylic bridge, took fingerprints inch by inch, and carefully recorded every detail. They wished they could record the entire crime scene. Move the walls and the room together to the laboratory and examine them with microscopes and flasks.

Realistic crime scene: Within the crooked blockade of Old Baba, the villagers broke in without scruples, politely brought water to the police officers, and at the same time asked themselves, their children, relatives and friends about the bad things they had heard. What can be done? After being punished, he apologized honestly, rinsed his mouth with tea, and vomited on the ground at the crime scene. At the same time, the criminal policemen were cursing and taking a rough picture of the scene in the house, then took a few fingerprints and footprints from more obvious locations, and then stuffed the common objects involved in the case into plastic bags, leaving only Important evidence involved in the case is put into numbered evidence bags, but there are often multiple quantities of cotton swabs and debris in an evidence bag.

Therefore, it sounded outrageous for unrelated villagers to engage in full-scale martial arts at a crime scene, but no police captain questioned it.

In fact, it is quite outrageous. Over the past few years, a police team may only encounter such murder scenes once or twice, so it seems more credible.

"The death of the deceased was so tragic, why did the villagers still watch and take photos?" Wang Chuanxing was still young, so when he was taking notes, he felt that it didn't make sense.

Bai Jian said calmly: "Someone vomited, and they vomited at the crime scene. We took DNA. But the more people who felt disgusted, the more people wanted to challenge it. After our police officers arrived, some people climbed over the wall and came in. of……"

"The marks on the wall were also destroyed?"

"I took it too." Bai Jian paused and said, "If it's on site, it will be protected now."

Now that the case is shared here, people around are already shaking their heads.

Although Bai Jian didn't say it explicitly, everyone was a police force manager at the same level, so they could more or less guess what Bai Jian was thinking.

For example, he said that he would consider love killings and acquaintance killings in advance. Why did he consider it like this? Isn't it because this is the probability of successful detection. If the crime was not committed by an acquaintance, not by passion, or by love, but by a stranger, this case would most likely be one of the serial murders.

Bai Jian didn't want to verify this possibility, because it would be useless. Shiting County did not have the resources and ability to face such a case. Needless to say, just the most basic murder-hunting package: prepare half a squadron of twelve or three people, and send three or four people to fly there wherever there are clues. Accommodation and meals are provided according to the standard, rent a car locally, and ask for help from time to time. The local police comrades bring back one suspect every week on average after one meal... In less than three months, the county bureau will stop paying wages.

If Jiang Yuan could not be invited, Bai Jian would have no choice but to ask for help from the Qinghe Municipal Bureau and the Provincial Department in the latter situation.

Bai Jian looked at Jiang Yuan eagerly.

Jiang Yuan examined the photo of the victim for a long time, looking at the deceased's exposed white teeth and roots, as well as the half-exposed skull, and said: "The scalp and face were peeled very loosely, and there is no technical aspect to it. From this point of view, professionals should rule it out. Otherwise, if you want to scalp the scalp normally, you would cut it from here..."

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

"Yes, it has been sent to Changyang City for analysis." Bai Jian said: "At present, it is consistent with a rope sold in small shops."

"Blunt force injury on the head... this should have been a wooden stick. Have you found any that match it?" Jiang Yuan's tool mark identification is also LV6, and he can draw a conclusion directly after looking at the photo.

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

When a person is injured or dies, what is the tool that caused his death? This identification is still relatively difficult. At the very least, the medical examiner in Shiting County failed to complete it successfully.

Jiang Yuan took a photo and put it on the table, and then took another photo of the scene and said directly: "Judging from the diameter and strength of the wooden stick, I tend to use it to push the door. Look at the door stick of the victim's house. Door sticks should be placed at this location of the gate every day. If you don't find it at the crime scene, you have to visit and ask around, and then look around. Such a thick wooden stick should not be easy to handle. "

"Okay, okay." Bai Jian nodded quickly, feeling much more at ease.

To put it bluntly, Jiang Yuan's ideas for solving the case were actually similar to Bai Jian's. They both used their own strengths and advantages to try to make breakthroughs in the facts of the case, but their abilities were different.

"Captain Jiang, is the fleet ready to go to the scene?" Wang Chuanxing came over to report.

"Let's go. Bring two more cars with you so we can find things." Jiang Yuandao said.
