Chapter 891 I Want Xu Taining

"This question is indeed crucial and a good question." Jiang Yuan thought for a moment and said, "Then let's start with the survey in this direction."

"Well, okay..." Sheng Bogong said, and when he was about to continue speaking, he saw Jiang Yuan had already walked forward.

Sheng Bogong was stunned for a moment, then he realized that Jiang Yuan had already started the survey.

Sheng Bogong hesitated for a moment, unsure whether to continue talking. Investigation is a meticulous job, especially for a major case like this. It cannot be investigated in a short time. Should he finish what he wants to say?
Sheng Bogong turned his head to look at Wang Sheng, then approached the captain and whispered to him, "The direction of our investigation is not completely determined. In this regard, should we discuss it with Captain Jiang, or decide on our own? I think Captain Jiang wants to do an analysis of the traces of the explosion. Although this is quite direct, it may not necessarily produce results. The main thing is, Captain Jiang should be a forensic doctor, right? Ningtai Jiang Yuan is quite famous, but in my impression, he seems to have only worked on one explosion case, and he didn't do an explosion analysis..."

Wang Sheng quickly said, "Just follow him and try. You have to do the explosion analysis anyway, so you can listen to Captain Jiang's ideas first. If it works, that's great. If not, we can talk about it later. As for the key steps, if you are confident, do it yourself. Then I will discuss it with Director Song."

Wang Sheng still trusts his subordinates. The opinions of technicians are not effective only when it comes to promotion and salary increase, but they still carry a certain weight at other times.

Sheng Bogong understood what Wang Sheng meant and felt more at ease. He quickly followed Jiang Yuan, thinking about watching with Jiang Yuan for two hours first. If there was still no clear direction after two hours, he would discuss it with Jiang Yuan.

At this time, Jiang Yuan saw Sheng Bogong catching up, so he waved and said, "Look at the center of the explosion."

"This is the center point." Sheng Bo frowned. He was the one who told Jiang Yuan this point.

"Look at the photos we took before." Jiang Yuan asked Miao Ruixiang, who was following him, to show the PAD in his hand to Sheng Bogong.

Sheng Bogong took a look and said in confusion: "This is indeed what we filmed before. Is there a problem with this...?"

"No problem. Let's discuss the phenomenon and then draw conclusions." Jiang Yuan looked at Sheng Bogong seriously and said, "I just compared these photos at the scene and can determine that the explosives were detonated in the air... In addition, look at these body parts..."

Jiang Yuan was pointing at the several blurry body parts around the explosion point.

Sheng Bogong looked bewildered and said, "I don't know much about forensic medicine..."

"These body parts belong to the same person." Jiang Yuan is now at LV6 explosion trace identification, combined with LV4 forensic evidence science, combined with LV4 forensic pathology, plus LV5 crime scene investigation, and LV3 forensic anthropology... Confidence arises spontaneously when talking about these on-site judgments.

Sheng Bogong couldn't keep up with Jiang Yuan's pace, but he subconsciously frowned and said, "These body parts seem to have been broken into pieces, and there are no clothes or accessories attached to them..."

"During the explosion, the clothes and outer layer should have been wiped off." Jiang Yuan never kept things in suspense, and continued to play the straight ball, saying: "The appearance of this scene is a typical explosion scene of a human bomb. In other words, the murderer, at least one of the murderers, was wearing a bomb vest and was killed on the spot."

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

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

Sheng Bo grunted twice and said, "Human bomb."

"Are you sure?" Wang Sheng's face changed.

Whether people are familiar with the matter or not, the first thing they would think of is terrorism. For inland provinces, when it comes to such things, they must treat it as a major enemy.

"Confirmed. The bomb exploded more than one meter above the ground. The range and state of the explosion are consistent with the characteristics of a human bomb..." Jiang Yuan paused here and said, "To confirm further, we need to find the remains of the explosive."

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

"Wait a moment." Jiang Yuan stopped Wang Sheng and said, "Based on the current situation, I think it is necessary to increase manpower and strengthen the investigation. Please ask for your instructions."

"Hmm...are there not enough people?" Wang Sheng looked around at the hundreds of police officers digging for life in the ruins, and turned around: "Okay, how many more people do you want? I should be able to borrow some from the Municipal Bureau and the police station."

Most of the personnel that his criminal police detachment could mobilize have already been deployed, but it is still possible to temporarily transfer some more personnel.

Jiang Yuan shook his head and said, "We need more professional personnel and more specialized equipment. In addition, we need a more professional organization. I want Xu Taining."

"Xu Taining?" Song Tiancheng also came over at this time. Hearing this familiar name, he thought for a moment and said, "A square-faced, very dignified man? Is he the first-class senior police officer who specializes in investigations in Shannan Province? The one who is particularly good at spending money?"

Wang Sheng was reminded and obviously knew who Xu Taining was. He said hurriedly, "Why are you talking about investigation? It's not the investigation stage yet."

"Judging from the current on-site environment, finding explosives is extremely difficult, no less than an investigation. Director Xu has strong organizational skills and is rigorous in his work, making him very suitable for deploying personnel and managing the scene in this environment." Jiang Yuan usually would not use Xu Taining if he could, but in this case, Xu Taining was extremely necessary.

Firstly, he didn't need to save money for Esu, and secondly, time was tight and the task was heavy.

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

Sheng Bogong stepped forward hesitantly and said, "Captain Jiang, we should be able to guarantee your expertise..."

Jiang Yuan shook his head: "I'm not just talking about surveying expertise, but also engineering expertise. For example, the collapsed floor slab here, should we find professional machinery to remove it? In fact, given the state of this building, for safety reasons, we should also conduct survey and demolition at the same time."

Sheng Bogong: "Well... we can indeed hire some people..."

"Secondly, we need to do a grid-based survey." Jiang Yuan looked at Wang Sheng and Sheng Bogong, and seeing that they were still frowning, he continued, "Third, judging from the situation at the scene, some of the surveyors have never surveyed such a large explosion site. The evidence collection seems to be very messy, and the management of items at the scene is very chaotic. In terms of forensics, a lot of body fragments have been extracted and fixed, but the scene has not been completely processed."

When talking about grid survey, Jiang Yuan still tried to save face, but he was less restrained in what he said later.

When Wang Sheng heard what Jiang Yuan said, and then looked at Song Tiancheng's face, he knew that Xu Taining was indispensable. He gritted his teeth and stamped his feet, saying, "Then please ask Xu Taining to come. However, if the leader asks me the purpose of inviting Xu Taining, how can I explain it more clearly?"

"For example, many of the things we are looking for are damaged due to the explosion, and their sizes may have changed greatly. At this time, ordinary searches are no longer enough." Jiang Yuan explained briefly, and then continued: "In addition, due to the shock wave generated by the explosion, the fragments of these explosives are likely to penetrate into the soil or even other evidence, such as these corpse muds..."

Jiang Yuan drew a circle with his hand and said, "Everything in this 100-square-meter room must be carefully checked. All collapsed cement slabs must be lifted up and checked. Every inch of the 100-meter radius must be searched. Only based on the evidence obtained can the nature of the explosive be determined."

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

"The key is to see if the detonator can be detonated remotely or with a delayed detonation." Jiang Yuan looked at Wang Sheng and said, "If it is a simple pull-type, loose-type or pressure-type, then we can assume that it is a suicide attack for some reason and that all or some of the participants have died. Otherwise, we have to assume that the murderer is still at large."

This couldn't be made clearer. Wang Sheng took a deep breath and said, "I understand. I will report this to my superiors now."
