National Forensic Doctor

That night, Jiang Yuan arrived in Luojin City on a business jet.

After resting for a few hours, at five o'clock the next morning, Jiang Yuan's backlog case team was loaded into several vehicles and rushed to Songxiang Park.

This community park is not big, and the access control is far from strict. There are four gates in the east, west, north, and south, and the fence is only a symbolic brick and stone fence as high as one person. The dedicated ground parking lot is quite large, and everything is put first to serve the surrounding residents. The security guard in the parking lot is the only park management staff that tourists can come into contact with. The rest are holed up in a small building hidden in the woods. No one knows whether they are working or not.

When Liu Wenkai saw this small office building and the quiet, almost deserted environment, he couldn't help but sigh: "It's really fun to do gardening. What's the difference between this and getting a salary for free?"

"Everyone sells their time and labor force, so there is no difference!" Qiu Liling, the little girl who led the way, spoke sharply and dismissed Liu Wenkai without any scruples.

Liu Wenkai smiled when he heard this, but he did not feel embarrassed in front of his colleagues. Instead, he apologized and said: "It's my fault. The leader's child just knows how to talk."

He wouldn't say the same thing in Shannan, because people can get to you if they don't do it well. But in Luojin City, there is not much of a problem. The parents of the second generation who have to work in such a leisurely department are most likely to be middle-level people - Liu Wenkai also knows some official reasoning.

The little girl Qiu Li who led the way wrinkled her nose and said angrily: "Who is the leader's child?"

"What about you?" Liu Wenkai calmed down and smiled.

Qiu Li was wearing jeans, with long hair hanging over his shoulders, and curved eyebrows. He gave him a handsome look and said nothing. After a while, he said again: "I came in through the public examination."

Liu Wenkai just smiled this time without replying.

Pushing open the office door, the director of the Park Management Office and several deputy directors were waiting inside.

Liu Wenkai skillfully made requests, took down mobile phone numbers, determined contacts, retrieved surveillance videos, etc., all in one go. Then he took Qiu Li to the park site.

Qiu Li was silent all the way. As he approached, his steps suddenly slowed down and he asked, "Is there really someone dead in our park?"

"It's not clear yet." How could Liu Wenkai leak the news to her.

Qiu Li didn't believe it and said: "You have dozens of people here. If you don't know clearly, why are there so many people here? Moreover, you are from other provinces. Are the people who died from Shannan Province?"

She only saw Liu Wenkai's ID card and didn't know the origins of the others.

Liu Wenkai still just smiled, but said: "The park here is so remote, there must be a lot of people killed. When you get off work in the morning and evening, have you ever seen ghosts?"

The little girl's eyes were clear and straightforward, and she asked nonchalantly: "Why do you ask that?"

Liu Wenkai: "Have you ever heard of the Dragon Group?"

…

Jiang Yuan wore shoe covers, a mask, a headgear and gloves and walked around the lawn covered in dog feces. He felt as if he was being hostile to the dogs around him.

The police's warning coil is so large that it directly covers the entire clover lawn. This is not the case at the scene of ordinary murders. But in the case involving Jiang Yuan, the Luojin City Criminal Police Detachment did not dare to do anything. of neglect.

In contrast, the dogs waiting outside the lawn were puzzled and angry, some of them were particular, and their legs began to shake at this time.

What's the point of not being allowed to enter a good shit place?

"The scene is probably in this area." Jiang Yuan came to a lush grass, drew a small circle in front of him, and said: "Large areas of clover, a small amount of wind-pollinated plants, and dense shrubs on the right. You can isolate a large amount of pollen from the roses next to you. If you continue to move forward, the number of rose pollen will actually increase..."

Qiao Shengli was also dressed and looking in front of her. Listening to Jiang Yuan's words, she looked at the map of the park and the scene, and said with admiration: "I didn't consider this bush..."

"Because the pollen map is certain, all we need to do is find a match." Jiang Yuan told Qiao Shengli several specific plans.

Qiao Shengli has almost finished her doctoral thesis, and has published two articles in the first section. Listening to the case is useless, but listening to the professional content of forensic botany only makes her feel passionate.

At this time, the little girl from the park management office also came over and saw a man and a woman on the lawn from a distance.

The intellectual beauty with long, straight black hair and big breasts instantly attracted the attention of the little girl Qiu Li. She first lowered her head and saw her feet, then couldn't help but look at the lawn, and couldn't help but said: "Who are these two people? What are the eyes of this woman?" There’s water dripping out of it.”

"The woman is a female doctor, and the man is Medical Examiner Jiang." Liu Wenkai said coquettishly: "You put on shoe covers or something first, and let's go over and say hello to Captain Jiang and see if we have anything to ask you about the park. "

"Okay." Qiu Li nodded without hesitation. After getting dressed, he bravely walked towards the two people on the lawn.

Liu Wenkai felt something was wrong, looked at Qiu Li strangely, and said, "At this time, shouldn't you be able to shirk it?"

Qiu Li, a newly promoted civil servant, glanced at Liu Wenkai with the corner of his eye and said, "I like tall people."

The middle-aged cadre Liu Wenkai glanced at Qiu Li unexpectedly: "No...don't even ask, does Captain Jiang have anyone?"

"I've already seen a competitor, so it doesn't hurt to have one more." As Qiu Li spoke, he quickly dressed up and stepped onto the lawn.

The approaching figure immediately caught Qiao Shengli's attention.

Qiao Shengli and Qiu Li looked at each other, their eyes becoming serious.

At this time, Jiang Yuan's voice came: "Let's leave the lawn. We need to investigate this place carefully to see if we can find any clues about the victim."

"Is there no blood or anything?" Liu Wenkai, who was approaching, ignored Qiu Li and his expression began to become serious. He has participated in more cases and is now slightly familiar with forensic botany. He knows that the pollen map can prove that the victim once lay on this lawn, but it does not mean that he must have been killed here.

Of course, combined with the time of death of the victim and other factors, the probability of being killed in the park is very high, but it is also possible that he fell here, or simply fought a field battle, and then was killed somewhere else in a very short time.

Thinking of the field battle, Liu Wenkai couldn't help but observe the surroundings, and his brows frowned in thought.

Jiang Yuan was also in a state of contemplation, and said: "The victim's body is quite decomposed, but according to the current analysis, the victim may not bleed a lot when he was killed. In addition, due to the time, even if a small amount of blood is left, it may be decomposed."

The almost invincible luminol and other reagents in film and television dramas are best used in artificial buildings. Because there is a lack of natural decomposers in artificial buildings, blood stains and so on can exist for a long time, in units of ten years. Even if a lot of high-concentration detergents are used, it may not be able to clean them all.

Real nature does not need any detergents.

For thousands of years, tens of thousands of years, and millions of years, there are countless bodies that have died in nature, and there are countless bodies with higher body size and bone density than the human body. There is no piece of meat left.

In fact, there is no need for real nature. Even in farmland, the bones will be gradually decomposed. If there is no one to maintain the graves in the fields, they will basically disappear after three generations.

Although the park's lawn is far less strong, the dog feces-rich lawn still nourishes and trains a large number of decomposers. If the victim's bleeding is not large, a few days will be enough.

In addition, the DNA of lawns with sufficient organic matter is also very chaotic. Even if there is only a little left, it is too difficult to find it without evidence in such a large area.

"In this case... wouldn't it be a waste of time?" Liu Wenkai thought of the business jet he had taken with him, and felt a little uncomfortable.

Jiang Yuan drove the LV5 crime scene investigation and said calmly: "Take samples first, and then we'll look at the surroundings."

The crime scene is not just a murder scene. The routes of the suspects in and out, and even any changes in the surrounding environment, are all part of the crime scene. The daily investigation of the police must also involve these.

Liu Wenkai was a little concerned, of course, mainly because this was not his specialty.

Jiang Yuan did not say anything, and took his junior brother and another criminal technician from Luojin City to walk around the park.

Near the lawn, there were not only Pang Jidong and Xu Ju from Luojin City, but also Huang Qiangmin from Ningtai and Jian Louyuan from Lanyue.

Everyone's expression was particularly solemn.

This case had in fact become a case jointly handled by the three provinces, and for disciplined forces like the police, honor always comes first.

A force fed with money can never be compared with a force fed with honor - because human needs are infinite, while material is limited, and only spiritual honor can perfectly match human spiritual needs.

No matter how much money is given, there will always be a time when it is not enough. No matter how much money is given, when it comes to exchanging life for life, people will hesitate. Only honor can make people sacrifice their lives.

Therefore, disciplined forces usually put honor first.

This case has made the teams of the three provinces pull the strings to the fullest.

Qiu Li felt the atmosphere around him, and his body, which was raised in the idle department, suddenly became excited, and followed Jiang Yuan at the first time.

"There are not many cameras in the park, and the positions are relatively ordinary. Despite this, the murderer was able to completely avoid the cameras, which shows a certain degree of professionalism." Jiang Yuan - Technical Defense Monitoring Technology (LV3) \u0026 Image Detection Trajectory Analysis (LV6)

"There are no guards at the entrance of the park, and the camera at the east gate is also crooked, but it should not be through the east gate. The surrounding walls are very low, and the fence is built on a brick and stone structure. The brick and stone structure can be stepped on, and the fence is also damaged... Considering that the murderer has the ability to carry the body for more than 300 meters, it should not be difficult to climb over such a fence." Jiang Yuan - Wall Building (LV4) \u0026 Forensic Evidence (LV4) \u0026 Crime Scene Investigation (LV5)

"The routes in the park are relatively hidden, and there are not many people. If the body needs to be dealt with, there should be many places in the park that can be considered. It is not difficult to carry it out, but it also shows that the murderer is very purposeful." Jiang Yuan - Identifying the Road in the Forest (LV2)

As Jiang Yuan spoke, Wang Chuanxing beside him took notes.

Qiao Shengli and Qiu Li stood on the left and right, listening to Jiang Yuan's confident tone, following Jiang Yuan with shining eyes, and looking at each other with suspicion.
