Chapter 414
Yellow warning tape.

Small white circles.

Red pool of blood.

Blue hood.

There are many more people.

When Jiang Yuan arrived at the scene, the only person who was idle was the smug Da Zhuang.

The shiny Rottweiler, with all the tendon and flesh, looks very lean.It probably felt that it had completed the task, lying there with a relaxed appearance, and when it saw Jiang Yuan, it held its head up high, as if a buddy didn't eat your shit for nothing.

Taking advantage of not wearing gloves, Jiang Yuan patted the dog's head a few times, almost patted Li Li's, quickly stopped, and said hello again, saying: "Is there no motion sickness on the road, it seems that Da Zhuang is in good condition?"

"If it's not on the winding mountain road, Da Zhuang can still take a car. Besides, he has been riding a car more often during this period, so he is somewhat used to it." Li Li pulled Da Zhuang's rope to make him look less obsequious. Master is ashamed.

"Da Zhuang did a good job." Jiang Yuan patted Rottweiler's face again, put on his gloves, and went to the scene.

The warehouse is converted from an old factory building.I don't know how long the factory has been in use. The doors and windows have long been abandoned, and the warehouse itself is also abandoned. If you want to use it, you may have to spend some money.

Qian Mingyu came a few minutes early and was already getting ready inside.Mu Zhiyang followed behind Jiang Yuan with the survey box, a small camera straddled his waist, entered the warehouse and started shooting.

For ordinary theft cases, it doesn't matter if you investigate casually, and even a little illegal operation.But when encountering a murder case, everyone's nerves are tense, and they will pay extra attention to operations.From a certain point of view, the attention and detection of homicide cases has also improved the standard operation of the police as a whole.

The bloodstains were in the corner of the warehouse near the entrance, and because of the shadows, it was not easy to find them.

When Jiang Yuan walked over, he saw that Qian Mingyu had already begun to take samples carefully.

In the face of the whole pool of blood, it is very simple to take a blood sample.Jiang Yuan watched directly with his hands tied, thinking while observing his surroundings.

Zhang Qi, the squadron leader of the third squadron, was the first to arrive. He didn't dare to disturb Jiang Yuan, and he also wanted to see Jiang Yuan's process of solving the case.This kind of emotion is like a classmate with a score of about 500 in the high school mock exam, looking at the students in other schools with a score of more than 700, and thinking to myself, when I do well in the exam, I can also get more than 500 in the exam. 550, if he does not perform well, it is estimated that he will only be 650, and the difference between everyone 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 and Homo erectus. But in the eyes of students with 500 points, as long as they are more careful and work harder , Seriously, enroll in two more cram schools, and it will be achieved.

The difference between me and Yao Ming is only in height——Zhang Qi looked at Jiang Yuan's concentrating expression, and thought to himself: This guy is quite tall, and he knew how to drink milk when he was young.

"Take a few more blood samples from the wall." Jiang Yuan saw that there were later traces joining the battle group, so he commanded.

He hasn't broken away from the overall thinking. On the other hand, today's blood sample is easy to take, and he doesn't need to do it himself-the criminal staff in Miaohe County must be given a little room to play.Furthermore, these inspection materials were also sent to the criminal squadron of Miaohe County for processing, and finally fell into their hands.If necessary, Jiang Yuan would take samples by 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 criminal center such as the laboratory.Not to mention the corresponding laboratory personnel who refused, they must be 88 times more serious when they see the samples he submitted for inspection.

There are three tracers in Miaohe County. They happen to be three generations old, middle-aged and young. They all look around LV1, which is considered to be a relatively good inheritance.Unlike Ningtai County, if Jiang Yuan hadn't come to Wang Zhong's place, the inheritance would have been severed.

"The dog won't die, right?" Zhang Qi asked in a low voice, looking forward to it.

"This should be the scene of two people fighting, and there is a high probability that there will be no dogs involved." Jiang Yuan saw it clearly and answered with certainty.

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

His No. [-] Squadron has now been reorganized into the Paw Paw Team, but the Paw Paw Team's first mission has nothing to do with dogs?

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

Jiang Yuandao: "Da Zhuang probably came here after smelling the smell of blood. Osmanthus may or may not have been here, and it is impossible to be sure now."

It has to be said that in terms of the working ability of police dogs, Da Zhuang is at the level of LV2, and it is not balanced.

In other words, because of the lack of money in Ningtai County, they always want to spend a small amount of money to do big things. To buy a dog, they want a comprehensive police dog, so they have never trained Da Zhuang to be particularly strong.

However, Jiang Yuan didn't count on the police dogs too much.In fact, a dog that has been lost for more than ten days is more difficult to find than a person who has been lost for more than ten days. If there is any way to find it, it is almost impossible.

Doing this kind of case is like doing a murder case.If the case is not solved within 24 hours of the incident, everyone will have to get nervous, and then use all available means and all clues that can be pursued. Moreover, one must pursue a clue that cannot be pursued before stopping.

Only with this kind of saturated investigation plan can it be possible to solve such a difficult case.

Therefore, why there are so many theft cases left in Miaohe County, on the one hand, the resources are used for major cases, and on the other hand, it is because some theft cases in Miaohe County also require saturated investigation Only then can the plan be carried out.

This is the troublesome place where hard power is not enough, so we can only find another way.

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

Zhang Qi was not reconciled, and asked: "Is it possible that someone hugged the dog, or met the dog and took it away?"

If no one was killed, this case would be a serious injury case at most. It would be the best if the work of the Wang Wang team could be eliminated by the way.

Jiang Yuan shook his head slightly: "There was no sign of a dog at the scene, no footprints, no fur, footprints coming and going, and no support for holding objects.

When you look back, you can catch someone and ask them to see the situation. "

"Shall we catch it?" Zhang Qi hesitated.

"You can discuss it with your captain." Jiang Yuan didn't care who was going to arrest him.

But arrest 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 with a minor injury of level two, they will also enter the classroom for fighting each other.As for what legitimate defense is, the judgment is so harsh that ordinary people cannot reach it.

In short, not fighting is the most sensible way of communication, and fighting must be the safest way to hug and spank.

Zhang Qi let out an "hey" and turned to make a phone call.

In his heart, he felt unspeakably uncomfortable. The dog hadn't been seen, and this was another serious injury case, so it was not good to torture to extract a confession, otherwise, all the dogs in Miaohe County would have to be renamed Osmanthus fragrans!
The team leader was already on his way here, but when he received the call, he rushed over quickly.

"How is it?" Team leader Xu Xuewu's voice was loud and sounded very sunny.

In terms of personal image and charisma alone, Xu Xuewu is at the level of LV3.9.

Jiang Yuan nodded to Xu Xuewu and the policemen who came with him: "Current preliminary judgment, this is the scene of two people fighting."

"How do you know it's a fight scene between two people?" Xu Xuewu asked.

"You can analyze it just by looking at the blood stains." Jiang Yuan smiled politely at Xu Xuewu.Other than that, he didn't explain to the Muggles any more about the application of backtracking magic in open buildings in sunny weather.

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

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

"What happened later?" Xu Xuewu loved listening to stories.

Qian Mingyu sighed: "Later, the teacher gave us an introduction, saying that the blood density of human beings is 1.050 to 1.060, the pH value is 7.3 to 7.4, and the osmotic pressure is 303.7 millimoles per liter. See how clearly I remember it. I looked it up in the book at the time, and what the teacher said was correct. However, just because I went to 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 expressed that they had the same experience.

Xu Xuewu nodded in a daze. In retrospect, the classes he took in college basically seemed to follow such a process.That's okay, most people are the same anyway.

Jiang Yuan had already looked around at this time, and said slowly: "According to the blood, the time of the incident should be seven days ago, and I tend to be in the afternoon and evening. This can be seen from the coagulation state of the blood and the degree of precipitation. We can figure it out. 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 hands in the air to describe.

Holding the camera, Mu Zhiyang frantically recorded all the places Jiang Yuan pointed out.

Zhang Qi, who just came back to his senses, opened his eyes wide to observe the surroundings, as if he only saw a line of words——Answer: slightly

Jiang Yuan said to the camera and Qian Mingyu at this time: "The two sides should not be ordinary people. One side uses a very sharp small dagger, and the other side fights to the death with bare hands, and occasionally counterattacks, and persists until the backup I left after coming here, although there was a lot of blood, but I think that neither of them should have died. It is likely that both of them have previous convictions."

"Fighting between gangsters?"

"It's about the same. I feel that it can be more advanced. There are sharp and deadly weapons." Jiang Yuan paused and said: "The blood loss of two people can add up to [-] milliliters. One person Blood loss dominates."

Ordinary people donate 400ml of blood. Under special circumstances, 800ml can be drawn, which is already a lot, and it is done in a controlled and quiet environment.The two fought and lost more than 1000 milliliters of blood. As long as they didn't faint, they were considered to be in good physical condition.

Jiang Yuan looked at it for another minute or two, then gesticulated with his arms in the air, and said, "The man holding the dagger has a very short dagger. It should be able to be used with both hands, and there is an exchange between them. Another person may borrow his dagger. , and wounded the person holding the dagger. Looking at it this way, the attacker is a little younger, 2 years old, 25 cm tall, and weighs 165 catties. This person should be very concerned about height, and he was wearing height-enhancing shoes when he came out to kill."

"The one who was attacked, well, judging from the scene, this one should have been ambushed. The attacked person was 38 years old, 180 centimeters tall, 200 kilograms in weight, strong and muscular, and his shoe size was 44. Size 45, big feet."

"Check the DNA, maybe you can find a match, and then look for a hospital. This kind of serious injury will heal within a week. It's not easy. At least you need to recuperate for a few days. And it's all combat injuries. If the hospital doesn't call the police, it will Going to the clinic."

When Jiang Yuan spoke, Mu Zhiyang raised the camera to shoot.

After he finished speaking, Zhang Qi understood a little bit, and asked a little bit puzzled: "How can you tell? Can you tell by height and age?"

Similar words, he asked a day today.

Jiang Yuan was not surprised, so he explained casually: "The height and age can be seen from the footprints, and there is a lot of floating soil accumulated in the warehouse, which can be seen clearly."

"Is that so..." Zhang Qi muttered to himself, then turned his head and said, "However, I kind of guess who the injured person you mentioned is."

Zhang Qi is a local aborigine, and he 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 biggest convoy over there belongs to Lao Jia. This man often fights, and he is from the police station. Regular customers, usually a bit aggressive, height and weight are all in line."

Zhang Qi talked more and more energetically, and suddenly felt that today's weather was good and he was full of emotions.
