When Jiang Yuan arrived at the scene, the only person who was idle was Da Zhuang, who had a proud face.
The glossy Rottweiler, with its tendons all over, looked very lean. It probably felt that it had completed its task, lying there relaxedly. When it saw Jiang Yuan, it held its head high and its chest high.
Dude, it doesn't look like you're eating 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 head. 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 embarrassed.
"Well done, Da Zhuang." Jiang Yuan patted Rottweiler's face again, put on his gloves, and went to the scene.
The warehouse was renovated from an old factory. I don’t know how long the factory has been in use. The doors and windows have long since been scrapped. The warehouse itself is also in disuse. 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 when he entered the warehouse.
In an ordinary theft case, a casual investigation and a few illegal operations will not matter much. But when encountering a murder case, everyone's nerves will be very tense, and they will pay special attention to operations. From a certain perspective
He said that the emphasis on and detection of murder cases has also improved the police's standardized operations 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 carefully take samples.
Facing the whole pool of blood, taking a blood sample was a very simple matter. Jiang Yuan just watched with his hands tied, thinking while observing the surroundings.
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 emotion was like that of a classmate who scored around 500 points on a high school mock exam.
Looking at the students from other schools who had the same score of over 700, I thought to myself, when I did well in the exam, I could also score over 500. If I performed well, I would get 550. If he did not perform well, he would probably only get 650. The difference between us is only 100 points.
.
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 you are more careful and work harder
, be more 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 of Miaohe County must be given some room to play. Furthermore, these test materials
It was then sent to the Criminal Division Squadron of Miaohe County for processing, but it eventually fell into their hands. If necessary, Jiang Yuan took samples himself and sent them to the provincial department or Changyang City.
He has been selling in Changyang City for so long, and among other things, he is very familiar with the people in the laboratory and other criminal investigation centers. The corresponding laboratory personnel, let alone refuse, must be serious when seeing the samples he sent for inspection88
Just double it.
There are three trace inspection personnel in Miaohe County. They happen to be three generations old, middle and young, and they all look like LV1, which is considered to be a relatively good inheritance. Unlike Ningtai County, if Jiang Yuan hadn't come and arrived at Wang Zhong's place,
Even if the inheritance is 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 Team Paw, but Team Paw’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. 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, it is because Ningtai County is short of money and 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 be nervous, and then they will use all possible means and pursue all the clues that can be pursued. Moreover, they must find a person.
Stop only when you can no longer pursue the clues.
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.
Only the plan can be implemented.
This is the trouble with not having enough hard power and having to find other ways.
Zhang Qi asked Qian Mingyu and the other two for trace inspection, 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 is killed in this case, it will be a serious injury case at best. If it can eliminate the work of the Paw Paw Team, that would be the best.
Jiang Yuan shook his head slightly: "There was no sign of a dog at the scene, no footprints, no fur, no traces of coming and going, and no gesture of holding something in his arms.
You can catch someone later and ask questions to find out the situation."
"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 2. Once someone is beaten to minor injuries level 2, the fight will also require admission to the squad room. As for legitimate defense, other
The harshness of judgment is beyond the reach of ordinary people.
In short, not fighting is the most rational way to communicate. If you must fight, picking her up and spanking her 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 hadn't 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 team leader 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 personality charm, Xu Xuewu is at the level of LV3.9.
Jiang Yuan nodded to Xu Xuewu and the policemen who came with him: "At present, the preliminary judgment is 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. Other than that, he did not explain to the 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 talking 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 loved listening to stories.
Qian Mingyu sighed: "Later, the teacher gave us an introduction, saying that human blood density is 1.050 to 1.060, PH value is 7.3 to 7.4, and osmotic pressure is 303.7 millimoles per liter. Look how clearly I remember it.
I even 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 basically follow 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 of them must have run away first, and the other got support and retreated."
As Jiang Yuan spoke, he waved his hand in mid-air to draw.
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, there was a counterattack, and they persisted until backup.
I 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 2,000 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 already a lot, and it is done in a controlled and quiet environment. Two people fought and lost more than 1,000 ml of blood. As long as they did not faint, they were in extremely poor health.
alright.
Jiang Yuan looked at it for another minute or two, then gestured with his arm 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. It can be used interchangeably. The other person may borrow his dagger."
, injuring the person holding the dagger. If you look 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 get a match, and then find a hospital. Such serious injuries can be cured in a week. It's not easy. You have to recover for at least a few days. And they are all injuries from a fight. If the hospital doesn't call the police, just
I need to find a clinic."
When Jiang Yuan said it, 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 questions like this all day long.
Jiang Yuan was not surprised at all, so he explained casually: "Judging from the height and age based on the footprints, there is also a lot of floating soil accumulated in the warehouse, so you can see clearly."
"That's it..." Zhang Qi murmured to himself, then turned around and said, "However, I have a little guess who the injured person you mentioned is."
Zhang Qi is a local native 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.
