Chapter 413: Solving the Case

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, who looked proud.

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 and its chest high, as if your brother 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. 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 came 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 even a few irregularities won't 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 a classmate who scored around 500 points in 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 enroll in 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. He knows how to drink milk when he was a child.

"Take more blood samples from the wall." Jiang Yuanzhi took command as he later 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 of Miaohe County must be given some room to play. Furthermore, these inspection materials will then be sent to the Criminal Division Squadron of Miaohe County for processing, and eventually fall 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 Team, but the Paw 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, there is basically no way.

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 kind of 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 of not having enough hard power and having to find another way.

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

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

If there is no death in this case, it is at most a case of serious injury. If it can eliminate the work of the Paw Patrol, it would be the best.

Jiang Yuan shook his head slightly: "There is no sign of the dog at the scene, no footprints, no fur, no footprints coming and going, and it does not support the posture of holding objects.

We can catch someone and ask him to see the situation."

"Should we catch him?" Zhang Qi hesitated a little.

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

But catching people is still necessary. The standard for mutual fighting in the police station is minor injury, that is, minor injury below level 2. Once someone is beaten to level 2 minor injury, the mutual fighting will also be sent to the detention room. As for what is 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, it is safest to hug and spank.

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

In his heart, he felt indescribable discomfort. He hadn't seen the dog yet. This was another case of serious injury, which meant that it was not easy to torture and extract a confession. Otherwise, all the dogs in Miaohe County would have to be renamed Guihua!

The captain was on his way here. He received the call and rushed over quickly.

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

In terms of personal image and personality charm alone, Xu Xuewu must be at the level of 9.

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

"How do you judge that it is a fight between two people?" Xu Xuewu asked.

"You can analyze it by looking at the bloodstains." Jiang Yuan smiled politely at Xu Xuewu. In addition, he did not explain to the Muggles the application of tracing magic in open buildings on sunny days.

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

Qian Mingyu had already collected a dozen cotton swabs at this time. He straightened his waist and raised his buttocks, as if he missed the girl he pursued in high school, and said: "Captain Jiang is talking about blood analysis. When I was in school, several teachers talked about the cases they solved, and they were really excited. They wanted to graduate and work immediately to clean up the world."

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

Qian Mingyu sighed and said: "Later, the teacher introduced us that the density of human blood is 0.50 to 0.60, the pH value is 3 to 4, and the osmotic pressure is 7 millimoles per liter. You see how clearly I remember it. I also looked it up in the book at that time. The teacher was right. However, because I looked it up in the book, I didn't hear it later. When I listened again, I didn't understand it."

"Me too."

"Almost."

The two trace inspectors said they had the same experience.

Xu Xuewu nodded absentmindedly. Thinking back, the classes he took in college basically followed the same process. That's fine. 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 tend to think it was in the afternoon or evening. This can be seen from the coagulation state of the blood and the degree of precipitation. Judging from the amount of bleeding and the footprints here, one person should have run away first, and the other person got support and retreated."

Jiang Yuan said while waving his hands in the air to describe.

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

Zhang Qi, who had just come to his senses, opened his eyes and observed the surroundings, as if he only saw one line of words - Answer: Omitted

Jiang Yuan was talking to the camera and Qian Mingyu at this time: "Both parties should not be ordinary people. One party used a very sharp dagger, and the other party fought to the death with bare hands, occasionally counterattacked, and insisted on waiting for reinforcements to come before leaving. Although a lot of blood was lost, I think both of them should not be dead. It is very likely that both of them had criminal records."

"A fight between gangsters?"

"It feels more advanced, with back and forth, and they still used very sharp and deadly weapons." Jiang Yuan paused and said: "The total blood loss of the two people can be about 2,000 milliliters, and the blood loss of one person accounts for the majority."

Ordinary people donate 400 milliliters of blood. Under special circumstances, 800 milliliters can be drawn, which is already a lot, and it is done in a controlled and quiet environment. Two people fight and lose more than 1,000 milliliters of blood. As long as they don't faint, they are considered to have very good physical conditions.

Jiang Yuan watched for another minute or two, then gestured in the air with his arms, saying, "The man holding the dagger has a very short dagger, which should be used by both hands, and they exchanged it. The other person may have borrowed his dagger and injured the man holding the dagger. From this point of view, the attacker is a little younger, 25 years old, 165 cm tall, and weighs 130 catties. This person should be very concerned about his height, and he even wore high-heeled shoes when he came out to kill people."

"The one who was attacked, well, judging from the scene, this person should have been ambushed. The attacked person is 38 years old, 180 cm tall, weighs 200 catties, has a strong body, is muscular, and his shoe size is about 44 or 45, and his feet are very big."

"Let's check the DNA, maybe we can find a match, and then find a hospital. This kind of serious injury will heal in a week, which is not easy. At least we need to recuperate for a few days. And they are all fighting injuries. If the hospital doesn't call the police, we have to find a clinic."

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

When he finished, Zhang Qi asked with some understanding, but also some confusion: "How did you tell? Can you tell the height and age?"

He asked similar questions all day today.

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

"Is that so..." Zhang Qi muttered to himself, turned his head and said: "But I have a guess about who the injured person you mentioned is."

Zhang Qi is a local native and knows the situation in Songxiang very well. He pondered and said: "There is a small logistics center in front of here. The largest fleet over there belongs to Lao Jia. This person often fights and is a frequent visitor to the police station. He is also a bit brave and aggressive. His height and weight are all in line with it."

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