Chapter 871: I Want Xu Taining

"This problem is indeed very critical, it is a good problem." Jiang Yuan thought for a while and said: "Then let's take this direction to investigate."

"En, good..." Sheng Bogong said, preparing to continue, when he saw Jiang Yuan had already stepped forward.

Sheng Bogong was stunned. Only then did he realize that Jiang Yuan had already started the investigation.

Sheng Bogong hesitated, not sure whether to follow up and continue talking. Investigation is a delicate job, especially for such a big case. It is not something that can be investigated clearly in a while. Should the words that should be said be finished?

Sheng Bogong looked back at Wang Sheng, then approached the detachment leader, and discussed with him in a low voice: "Our investigation direction here has not been fully determined. In this regard, should we discuss with Captain Jiang, or decide for ourselves? I see Captain Jiang wants to do explosion trace analysis. In this regard, although it is quite direct, it may not necessarily produce results. Mainly, Captain Jiang should be a forensic doctor? Ningtai Jiang Yuan, the reputation is quite big, but in my impression, he seems to have only done one explosion case, and he didn't do explosion analysis..."

Wang Sheng said quickly: "You follow him first to do it. Anyway, you are going to do explosion analysis. You can listen to Captain Jiang's ideas first. If it works later, it is best. If it doesn't work, talk about it. For key steps, if you have confidence, you do it yourself. When the time comes, I will discuss with Director Song."

Wang Sheng still trusts his subordinates. The opinions of technicians only don't work when they are promoted and raised, and they still have a certain share at ordinary times.

Sheng Bogong understood Wang Sheng's meaning, felt a little more stable in his heart, and followed Jiang Yuan quickly, considering following Jiang Yuan for two hours first. If there was no clear direction after two hours, it would be just right to discuss with Jiang Yuan.

At this time, Jiang Yuan saw Sheng Bogong following, and waved his hand, saying: "Look at this explosion center point."

"This is the center point." Sheng Bogong frowned. He gave this point to Jiang Yuan.

"Look at the photos taken before." Jiang Yuan asked Miao Ruixian who was following him to show the PAD in his hand to Sheng Bogong.

Sheng Bogong took a look and said inexplicably: "This is indeed what we took before. This... is there a problem?"

"No problem, let's discuss the phenomenon, and then infer the conclusion." Jiang Yuan looked at Sheng Bogong seriously and said: "I just compared these photos at the scene, and I can judge that the explosive was detonated in the air... In addition, look at these body parts..."

Jiang Yuan pointed to several blurred body parts near the explosion point.

Sheng Bogong was at a loss and said: "I don't understand forensic things..."

"These body parts are from the same person." Jiang Yuan is now an LV6 explosion trace identification, combined with LV4 forensic physical evidence, combined with LV4 forensic pathology, plus LV5 crime scene investigation, and LV3 forensic anthropology... Speaking of these on-site judgments, confidence arose spontaneously.

Sheng Bogong couldn't keep up with Jiang Yuan's rhythm, but his body subconsciously frowned and said: "These body parts feel like they have been shattered, and there are no clothing accessories attached..."

"When the explosion occurred, the clothing and outer layers should have been wiped out." Jiang Yuan always didn't sell the pass, continued to play straight balls, and said: "The appearance of this scene is a relatively typical suicide bomber explosion scene. That is to say, the murderer, at least one of the murderers, was wearing a bomb vest and was blown to death on the spot."

"Ah... this..." Sheng Bogong was startled by Jiang Yuan's conclusion. This gave people too many associations.

Wang Sheng came over and asked: "What's wrong?"

Sheng Bogong snorted twice and said: "Suicide bomber."

"Confirmed?" Wang Sheng's face changed.

Anyone who knows or doesn't know this will hear it, and the first reaction must be terrorist behavior. For the inland province, involving this kind of thing, it must be like facing a great enemy.

"Confirmed. The bomb exploded more than one meter above the ground. The range and state of the explosion conform to the characteristics of a suicide bomber..." Jiang Yuan paused here and said: "If you want to further confirm, you have to find the wreckage of the explosive."

Wang Sheng nodded solemnly and said: "I have to report to the leader."

"Wait a moment." Jiang Yuan called Wang Sheng and said: "Judging from the current situation, I think it is necessary to increase manpower and strengthen the investigation. Please ask for instructions together."

"Um... is the manpower not enough?" Wang Sheng looked up and down at the hundreds of police officers who were digging in the ruins, said a sentence, but still turned over: "Okay, how many people do you want to increase? I should still be able to borrow some people from the municipal bureau and police station."

The manpower his criminal police detachment can mobilize has basically been mobilized. However, it is still possible to temporarily dispatch some manpower to come over.

Jiang Yuan shook his head and said: "Need more professional personnel, and special equipment. In addition, need more professional organization. I want Xu Taining."

"Xu Taining?" Song Tiancheng also came over at this time, heard this somewhat familiar name, thought about it, and said: "A square face, a very majestic person? Is it the first-class senior police officer who specifically does investigation in your Shannan Province? The one who is particularly good at spending money?"

Wang Sheng was reminded and obviously knew who Xu Taining was, and said busily: "Why talk about investigation? It's not time for investigation yet."

"From the current scene environment, the difficulty of finding explosives is very high, no less than an investigation. Director Xu has strong organizational ability and does things rigorously, which is very suitable for deploying personnel and managing the scene in this environment." Jiang Yuan usually doesn't use Xu Taining if he can, but this case really needs Xu Taining.

First, he doesn't need to save money for Esu Province, and second, time is tight and the task is heavy.

Wang Sheng couldn't help but look at Sheng Bogong.

Sheng Bogong hesitated and stood out, saying: "Captain Jiang, in terms of professionalism, we should still have a guarantee..."

Jiang Yuan shook his head: "I don't just mean professionalism in investigation, but also professionalism in engineering. For example, the floor slab that collapsed here, should we find professional machinery to dismantle it? In fact, out of safety considerations, it should be dismantled while investigating."

Sheng Bogong: "This... can indeed hire manpower..."

"Secondly, we need to do grid-based investigation." Jiang Yuan looked at Wang Sheng and Sheng Bogong, and saw that both of them were frowning, so he continued: "Third, judging from the situation at the scene, some investigation personnel should not have investigated such a large-scale explosion scene. The evidence collection looks messy, and the management of items at the scene is chaotic. In terms of forensic medicine, many body fragments have been extracted and fixed, but the scene has not been processed."

When talking about grid-based investigation, Jiang Yuan still saved face, and later said it without scruples.

Wang Sheng heard Jiang Yuan say this, looked at Song Tiancheng's face again, and knew that Xu Taining was indispensable. He gritted his teeth and stomped his feet, saying: "Then please ask Xu Taining to come. However, if the leader asks me, what is the purpose of asking Xu Taining, how can I say it more clearly?"

"Just say, the things we are looking for, because of the explosion, many are in a damaged state, and the size and volume may also have great changes. At this time, ordinary search is not enough." Jiang Yuan explained slightly, and then continued: "In addition, because of the shock wave generated by the explosion, these explosive fragments are likely to drill into the soil, and even other evidence, such as in these body mud..."

Jiang Yuan drew a circle with his hand and said: "All the things in this 100-square-meter room must be turned over carefully. The collapsed cement slabs must be lifted and touched. Within a radius of 100 meters, you must also find it inch by inch. According to the evidence obtained, you can determine the nature of the explosive."

"The nature of the explosive?" Wang Sheng frowned.

"The focus is on the detonator, whether it can be remotely detonated, and whether it can be delayed detonated." Jiang Yuan looked at Wang Sheng and said: "If it is just a simple pull-type, loose-type or pressure-type, then we can assume it is a suicide attack of some kind, assume that the participants are all or partially dead, otherwise, we have to assume that there is a murderer still running outside."

This is as clear as it can be. Wang Sheng took a deep breath: "Understood, I will report it upwards now." ===== CHAPTER 872 =====
