Chapter 239: Delineating the Scope

Forensic expert Zhai first contacted the micro-evidence laboratory to confirm the queue-jumping, and then discussed the wear appraisal problem with the director of his own criminal science technology center.

The level of the provincial department's criminal science center was relatively high, and the annual funding wasn't small, so they knew quite a few scientific research institutes.

In fact, the opportunities for criminal science to truly use science weren't as many as imagined.

Under normal circumstances, crimes like theft were solved by internal agencies, and everyone was definitely too lazy to make it too complex.

Contacting external agencies both had certain rules and no fixed path to follow, so it was truly troublesome.

Only for homicide cases and major cases did everyone give a bit of face, and only then could it be truly done. Only then could those reports and expenses be found for leaders to sign and recognize.

But saying is saying, when external resources were truly needed, domestic scientific research resources were actually very abundant.

Too many scientific research institutes had long reached the level of "only you can't think of it, nothing I can't do."

Things like micro-evidence weren't fresh in high-end research institutes in the 70s and 80s. As for the work of snake-skin bag wear, it was a bit difficult for the Criminal Science Center to do, but if it were put into a laboratory that could do wear experiments, it was simply a piece of cake.

And laboratories that could do wear experiments could be chemical laboratories, inorganic material laboratories, organic material laboratories, metal material laboratories, mechanical laboratories, or professional friction laboratories, bearing laboratories, powder metallurgy laboratories...

Therefore, when the country talked about "must solve homicide cases," the meaning behind it was "not playing by the rules."

Famous foreign criminal investigation agencies, moving two or three detectives to solve cases, the support system behind them was no more than two or three kittens.

Domestic theft and robbery cases were almost the same mode, but when it involved homicide cases, when truly needed, many fresh little killers faced the mature scientific research system and investigation system of the country, which was likely a group of old guys facing a young person with little experience.

However, for this case, it was likely done by an old guy; in Zifeng Mountain, finding a young person wasn't easy either.

And forensic expert Zhai discussed everything, looked at the time, and only then called Xu Taining.

Xu Taining listened to half and interrupted forensic expert Zhai's words, asking: "Where are you, I'll go over."

Forensic expert Zhai was still a bit stunned and said busily: "We are at the Qinghe City funeral home, you don't need to make a special trip."

"I'll be there as soon as possible." Xu Taining didn't talk nonsense with him, hung up the phone, and then cursed forensic expert Zhai for being confused.

He didn't come to Zifeng Town for tourism; he was busy, creating a scale of thousands of people, all for the sake of solving the case.

And the experiments done by Jiang Yuan and others, although simple, were truly possible to solve the case.

In this situation, forensic expert Zhai actually thought for him...

Xu Taining just looked at forensic expert Zhai's old age and didn't open his mouth to curse directly.

In less than two hours, Xu Taining's two cars drove into the Qinghe City funeral home.

Director Meng Deyuan hurried out to welcome him.

Xu Taining couldn't manage him, shook hands for five seconds after getting off the car, and said "Let's go in first."

Meng Deyuan felt a bit of a gap, looked at Xu Taining's car butt, and said to his subordinate: "The temperature is lower than the soul."

"Soul egg?" The subordinate quickly gave a definition and silently sent it out in the group.

Xu Taining couldn't manage that much, nor was he afraid of offending the people of Qinghe City, so he went straight to find Jiang Yuan and the others, listening to their explanation on the spot, and drawing lines on the map.

At this time, forensic expert Zhai was still a bit embarrassed and explained: "Our autopsy hasn't ended yet, the judgment of the corpse source might still take some time..."

"The judgment of the corpse source is indeed very important." Xu Taining agreed, and added: "You still have to work hard on the corpse source work, we will look at the discovery of the corpse bag first."

Forensic expert Zhai had been doing technology for too long, to the point of forming a fixed thinking pattern, always feeling that the corpse had to be figured out.

Xu Taining didn't have such a habit. In his experience, the window for solving a case was just that little bit; seize the opportunity, catch the criminal, and he himself didn't care about the means.

For many accumulated cases, most means were actually unworkable; he would take whatever he could find.

In this regard, Jiang Yuan's thoughts were similar.

He was a forensic expert, but the means of criminal science he had accumulated were becoming more and more. Jiang Yuan no longer accepted having to solve cases according to the textbook mode.

Jiang Yuan explained the motorcycle experiment to Xu Taining in detail, and then, under Xu Taining's urging, a young police officer brought forensic expert Niu to do the experiment again.

Xu Taining didn't pay too much attention to the experiment process. Repeating the experiment was just his verification of the correct result. During this period, Xu Taining took out his mobile phone and made several calls in succession.

"The car that disposed of the corpse came from the north." With Xu Taining's urging, the micro-evidence laboratory truly jumped the queue for him.

Several police officers didn't look at the motorcycles and forensic expert Niu circling in the open space, and swarmed to the map.

"If it's wear, it's at least an hour or more. It also has a relationship with the way of driving and the position of contact." Xu Taining said: "Without determining the car model and placement position, it's difficult for them to determine. With more time, they might be able to give a more accurate range."

"At least an hour, if confirmed, is also a very useful conclusion." Standing on Xu Taining's side was another senior police sergeant Li Liang who came to support from the provincial department. At this moment, looking at the map, he said: "An hour, actually first excludes Zifeng Mountain and the surrounding townships."

Xu Taining's eyes lit up: "Makes sense."

For a corpse disposal case occurring near Zifeng Mountain, the biggest and most suspicious people must be in Zifeng Town and near the Zifeng Mountain Coal Mine.

Instead, if the distance was pulled further, the number of suspects would drop sharply. At this time, considering their intersection with Zifeng Mountain Coal Mine would be easier to find the suspect.

Jiang Yuan thought of Wang Guoshan for the first time.

Wang Guoshan chose to dispose of the corpse in the reservoir, which was also a similar situation.

He neither worked in the reservoir nor lived near the reservoir, but he had an understanding of the reservoir, and instead chose a car ride of more than an hour to specifically dispose of the corpse in the reservoir.

Another senior police sergeant Li Liang from the provincial department also completed the logical construction at this moment, drawing on the map with his hand, and said: "I think we can try to investigate these villages and townships 30 kilometers away from Zifeng Town, prioritizing missing females..."

Forensic expert Zhai felt like he could breathe, and said busily: "We are also analyzing the corpse source..."

"You can take photos of the jewelry to look for them first." Jiang Yuan opened the photos of the jewelry he had temporarily taken on his mobile phone and said: "The place where these jewelry were discovered belongs to the same plot as corpse source two and corpse source three. It is likely that they were jewelry worn or owned by the deceased. I think you can ask the families of the missing persons to see if anyone remembers them."

With Jiang Yuan's ability to do trash sorting, he was still relatively optimistic about the source of the jewelry.

People in different cities and with different incomes had different ways of throwing trash.

Don't look at them as cheap small jewelry; people in Changyang City might discard them as a set, but residents of Zifeng Town or other small towns nearby wouldn't be so wasteful.

Why did concepts like "decluttering" appear in Tokyo and become popular in some big cities in China? Ultimately, it was because the house area was too small; if one wanted to live more spaciously, one could only have fewer things.

Those villas with super large areas, in order to keep the rooms from looking empty and eerie, had to specially move furniture to the middle of the room. If they also learned to declutter, they would feel the room was like a yin house at night.

Xu Taining and the others didn't need to be popularized with these simple concepts and immediately said: "Can, wash some photos of the jewelry and take them to show the families and neighbors of the missing persons."

Following that, he urged them to analyze the corpse source again.

Forensic expert Cheng and Jiang Yuan both responded, but their confidence wasn't very sufficient.

Forensic anthropology was like solving an equation; it had simple solutions for some problems, such as age, race, or height, etc. As long as the bones were complete, these answers could definitely be given, just with a difference in confidence.

But for some problems, forensic anthropology didn't necessarily have a solution. For example, the area of life, the type of occupation, and even habits of life were very easy to misjudge or not be able to judge.

From Jiang Yuan's current observation, he wasn't too optimistic about obtaining information such as occupation or life from bones.

There was nothing to say about this; some people worked particularly hard, or the labor damage of work was particularly great, so if they died young, one could see the occupation or work content from the bones.

But some people might have very easy work, liked to slack off daily, the occupational disease wasn't obvious, and might not even have occupational disease, so wanting to judge the occupation through the skeleton was relatively difficult.

This was also the reason why Jiang Yuan recommended using jewelry to find people.

For Xu Taining, he had seen all kinds of situations. As long as there were clues, he could give himself a shot of adrenaline, and by the way, give his subordinates a shot of adrenaline.

At this moment, Xu Taining's work enthusiasm had already risen, shook hands with Jiang Yuan and the others, and was in a hurry to go back to arrange work.

The group of people came like a whirlwind and left like a whirlwind.

At this time, the motorcycles running circles at a speed of 30 kilometers per hour in the open space were still humming and turning.

Forensic expert Niu on the back seat hung his head, had already given up struggling, and was even a bit used to the space on the back seat of the motorcycle, occasionally adjusting his posture to make himself slightly more comfortable. ===== CHAPTER 240 =====
