National Forensic Doctor

Yellow caution tape.

Small white circles.

Red pool of blood.

Blue hood.

There are countless more people.

When Jiang Yuan arrived at the scene, the only person who was idle was Da Zhuang with a proud face.

The Rottweiler is shiny and shiny, with tendon meat all over, and it looks very lean. It probably felt that it had completed its task, so it lay there relaxedly. When it saw Jiang Yuan, it held its head high, as if your friend had not eaten your dog's food in vain.

Jiang Yuan took advantage of not wearing gloves and patted the dog's head a few times. He almost hit Li Li's. He quickly stopped and said hello again, "You didn't get motion sickness on the road, did you? Do you think Da Zhuang is in good condition?"

"If it's not a winding mountain road, Da Zhuang can still ride in the car. Moreover, he has ridden in the car more often during this period, so he is somewhat used to it." Li Li pulled Da Zhuang's rope to make it look less flattering. The master is in disgrace.

"Well done, Da Zhuang." Jiang Yuan patted Rowena's face again, put on his gloves, and went to the scene.

The warehouse is an old factory renovated. I don’t know how long the factory building has been in use. The doors and windows have long been scrapped, and the warehouse itself is also in ruins. If you want to use it, you will have to spend some money.

Qian Mingyu arrived a few minutes early and was already getting ready inside. Mu Zhiyang followed Jiang Yuan with the survey box, a small camera strapped directly to his waist, and he started filming as soon as he entered the warehouse.

In an ordinary theft case, a casual investigation and a few irregularities will not make much difference. But when there is a murder case, everyone's nerves are very tense, and they will pay special attention to everything. From a certain perspective, the emphasis on and detection of murder cases has also improved the standard operation of the police as a whole.

The blood stain is in the corner of the warehouse near the entrance. It is not easy to find because of the shadow.

Jiang Yuan walked over and saw Qian Mingyu starting to take samples carefully.

Facing the whole pool of blood, taking a blood sample is very simple. Jiang Yuan just watched with his hands tied, observing the surroundings and thinking at the same time.

Zhang Qi, the captain of the third squadron, was the first to arrive. He did not dare to disturb Jiang Yuan, and he also wanted to see Jiang Yuan's solving process. This kind of emotion is like that of a classmate who scored around 500 points on a high school mock test, looking at his classmates from other schools who scored over 700 points, and thinking to himself, when I do well in the exam, I can also score over 500 points. If I perform well, I will 550. If he didn't perform well, he would probably only have 650. The difference between us is only 100.

The difference of 100 points is a world of difference in the eyes of students with 600 points. In the eyes of students with 630 points, it is the difference between human beings and Homo erectus. But in the eyes of students with 500 points, as long as they are more careful and work harder , be serious and sign up for two more cram schools, and you can achieve it.

The only difference between me and Yao Ming is height - Zhang Qi looked at Jiang Yuan as he was concentrating on thinking, and thought to himself: This guy is quite tall, and he knows how to drink milk when he was a child.

"Take more blood samples from the wall." Jiang Yuanzhi took command as soon as he joined the battle group.

He has not yet broken away from the overall thinking. On the other hand, taking today's blood sample is simple and does not require him to do it himself - the criminal department personnel in Miaohe County must be given some room to perform. Furthermore, these inspection materials were then sent to the Criminal Division Squadron of Miaohe County for processing, and eventually fell into their hands. If necessary, Jiang Yuan would take samples himself and send them to the provincial department or Changyang City.

He has been selling in Changyang City for so long. Among other things, he is very familiar with the people in the laboratory and other criminal investigation centers. Not to mention rejecting it, the corresponding laboratory personnel must be 88 times more serious when seeing the samples he sent for inspection.

There are three trace inspection personnel in Miaohe County. They happen to be three generations old, middle-aged and young. They all look like around LV1, which can be regarded as a relatively good inheritance. Unlike Ningtai County, if Jiang Yuan hadn't come and arrived at Wang Zhong's place, the inheritance would have been cut off.

"Is the dog going to die?" Zhang Qi asked in a low voice, a little hopeful.

"This should be the scene of a fight between two people. There is a high probability that no dog is involved." Jiang Yuan saw clearly and answered with certainty.

Zhang Qi was stunned: "It has nothing to do with dogs?"

His No. 3 Squadron has now been reorganized into the Paw Patrol Team, but the Paw Patrol Team’s first mission had nothing to do with dogs?

Zhang Qi felt as if his brain had been stepped on by a dog.

Jiang Yuandao: "Dazhuang probably smelled the blood and ran over. Osmanthus may have been here before, maybe not, and we can't be sure now."

It has to be said that in terms of the working ability of a police dog, Da Zhuang is at the level of LV2, and it is also uneven.

In other words, because Ningtai County is short of money, it always wants to spend a small amount of money to do big things. When buying a dog, it wants to be a comprehensive police dog, so it has never trained Da Zhuang to have particularly strong characteristics.

However, Jiang Yuan didn't put much hope in the police dogs. In fact, a dog lost for more than ten days is more difficult to find than a person lost for more than ten days. If there is any way to find it, it is basically impossible.

Doing this kind of case is just like doing a murder case. If the case is not solved within 24 hours, everyone will become nervous, and then they will use all possible methods and pursue all the clues that can be pursued. Furthermore, the pursuit will only stop when there is one clue that cannot be continued.

Only this saturated investigation plan can solve a case of this difficulty.

Therefore, why there are so many theft cases in Miaohe County? On the one hand, resources are used on serious crimes. On the other hand, it is because certain theft cases in Miaohe County also require saturated investigation. The plan can only be carried out.

This is the trouble with not having enough hard power and having to find another way.

Zhang Qi asked Qian Mingyu and two other trace inspectors again, and they naturally supported Jiang Yuan's judgment.

Zhang Qi was unwilling to give in and asked: "Is it possible that someone was holding the dog, or that he met the dog and took it away."

If no one died in this case, it would be a serious injury case at most. It would be best if the work of the Paw Paw Team could be eliminated.

Jiang Yuan shook his head slightly: "There was no sign of a dog at the scene, no footprints, no hair, no traces of coming and going, and no gesture of holding something in his arms.

You can catch someone and ask them later to see what's going on. "

"Shall we arrest him?" Zhang Qi hesitated.

"You can discuss it with your captain." Jiang Yuan didn't care who would catch him.

But arresting people is still necessary. The standard for fighting at the police station is minor injuries, that is, minor injuries below level two. Once someone is beaten to a level two minor injury, even those who fight will have to go to the squad room. As for what constitutes legitimate defense, the judgment is so harsh that ordinary people cannot reach it.

In short, not fighting is the most rational way to communicate. If you must fight, picking him up and spanking him is the safest way.

Zhang Qi said "Hey" and turned around to make a phone call.

In his heart, he felt an indescribable discomfort. The dog had not been seen. This was another serious injury case, which meant that it would not be possible to extract a confession through torture. Otherwise, all the dogs in Miaohe County would have to be renamed Osmanthus!

The captain was on his way here when he received the call and rushed there quickly.

"How's it going?" Captain Xu Xuewu's voice was loud and sunny.

In terms of personal image and charisma alone, Xu Xuewu is at level 9.

Jiang Yuan nodded to Xu Xuewu and the policemen who came with him: "At present, it is preliminary judged that this is the scene of a fight between two people."

"How can you tell it's a fight between two people?" Xu Xuewu asked.

"You can analyze it just by looking at the blood stains." Jiang Yuan smiled politely at Xu Xuewu. Apart from this, he did not explain to Muggles any more about the application of traceability magic in open buildings on a sunny day.

Xu Xuewu said "Oh", as if he was seeing a computer for the first time, and immediately began to study its working mechanism, trying to find a person or a mysterious crystal from the case.

Qian Mingyu had already taken a dozen cotton swabs at this time. He straightened up and straightened his buttocks, as if he missed the girl he had chased in high school, and said: "Captain Jiang is talking about blood stain analysis. When I was studying , several teachers were really excited when they talked about the cases they had solved, and they wished they could graduate and work immediately and clean up the world."

"What happened next?" Xu Xuewu loves to listen to stories.

Qian Mingyu sighed: "Later, the teacher gave us an introduction, saying that human blood density is 050 to 060, PH value is 3 to 4, and osmotic pressure is 7 millimoles per liter. Look how clearly I remember it. I flipped through the book to check, and the teacher was right. However, just because I flipped through the book, I didn’t hear it later, and when I listened to it again, I couldn’t understand it.”

"me too."

"almost."

Two trace inspectors said they had the same experience.

Xu Xuewu nodded in a daze. Looking back, the classes he took in college seemed to have basically followed this process. That's okay, most people are the same anyway.

Jiang Yuan had already looked around at this time and said slowly: "Based on the blood, the incident should have happened seven days ago. I prefer it to be in the afternoon and evening. This can be seen from the coagulation state of the blood and the degree of precipitation. We have to come out. Judging from the amount of bleeding and the footprints here, one should have run away first, and the other got support and retreated."

Jiang Yuan said while waving his hand in mid-air to describe.

Mu Zhiyang held the camera and hurriedly wrote down everything Jiang Yuan pointed out.

Zhang Qi, who had just come back to his senses, opened his eyes wide and looked around, as if he could only see one line of words - answer: slightly.

At this time, Jiang Yuan said to the camera and Qian Mingyu: "The two sides should not be ordinary people. One side used a very sharp small dagger, and the other side fought with bare hands and refused to retreat. Occasionally, they would fight back, and they persisted until backup. They came here before leaving. Although there was a lot of blood, I think both of them were not dead. It is possible that both of them have criminal records."

"Gangsters fighting?"

"Absolutely. It feels a little more advanced. It goes back and forth, and the weapons used are very sharp and deadly." Jiang Yuan paused and said: "The total blood loss of two people can be two thousand milliliters. One person. Blood loss accounts for the majority.”

The amount of blood donated by ordinary people is 400 ml. Under special circumstances, 800 ml can be drawn, which is a lot, and it is done in a controlled and quiet environment. The two fought and lost more than 1,000 milliliters of blood. As long as they didn't faint, they were in very good health.

Jiang Yuan watched for another minute or two, then made famous gestures with his arms in the air, and said: "The man holding the dagger has a very short dagger. It can be used by both left and right hands, and it can be used interchangeably. The other person may borrow his dagger." , injuring the person holding the dagger. Looking at it this way, the attacker is slightly younger, 25 years old, 165 centimeters tall, and weighs 130 pounds. This person should be very concerned about his height, and he wears height-increasing shoes when he goes out to kill people."

"The person who was attacked, well, judging from the scene, this person should have been ambushed. The person who was attacked was 38 years old, 180 centimeters tall, weighing 200 pounds, with a strong and muscular body, and his shoe size was 44. I’m size 45 and my feet are big.”

"Check the DNA, maybe you can find a match, and then find a hospital. Such serious injuries can be cured in a week, which is not easy. You need to recover for at least a few days. And they are all injuries from a fight. If the hospital doesn't call the police, they will be fine." I need to find a clinic."

When Jiang Yuan started talking, Mu Zhiyang raised the camera to take pictures.

After he finished speaking, Zhang Qi asked with some understanding and some confusion: "How can you tell? Can you tell by height and age?"

He has been asking similar questions all day today.

Jiang Yuan was not surprised, so he explained casually: "Judging from the footprints, the height and age, there is also a lot of floating soil in the warehouse, so you can see clearly."

"That's it..." Zhang Qi murmured to himself, then turned around and said, "However, I kind of guessed who the injured person you mentioned is."

Zhang Qi is a local aboriginal and knows the situation in Song Lane very well. He thought about it and said: "There is a small logistics center in front of here. The largest fleet over there belongs to Lao Jia. This man often fights and is from the police station. A frequent visitor, he is usually a bit aggressive and aggressive, and his height and weight are all in line.”

Zhang Qi became more and more enthusiastic as he talked, and suddenly felt that the weather today was good and he was in a full mood.
