Chapter 663: Screening

The footprints of the mourner that Jiang Yuan found near the burial site were not particularly unusual in themselves. The height and age were average, and the weight was slightly light, but it was still a common weight in the tens of millions, making it impossible to point directly to the identity of Old Nine.

However, the act of worship exposes a lot of things.

This shows that there is an emotional relationship between Old Nine and the buried deceased. No matter if it is love, hate, or human suffering, in short, the act of worship completely drags the case from a serial homicide case back to an ordinary homicide case.

The most terrifying thing about serial killers is actually their anti-social nature. If it is a serial killer who has no desires, it is the most helpless, and most of those who do whatever they want are also very difficult to solve. Even if the police connect his brain circuit, they may not be able to effectively investigate.

Love killings are much better. Don't look at a person as if he knows many people, but in fact, the social limit of normal people is about 500 people, and those who can maintain social interaction are about 150 people. This is the so-called Dunbar's 150 law.

And from the perspective of criminal police, it is impossible for these 150 people to be all enemies, right?

Those who can produce love, hate, and hatred to the extent of needing to kill are naturally even fewer.

Therefore, hearing Jiang Yuan's discovery, without Liu Jinghui's reminder, the criminal police who often handle cases can think of eighteen ways to solve the case in their minds.

Tao Lu went directly to the scene by car.

Liu Jinghui, Li Haochen, Cui Xiaohu, and others accompanied him.

When they arrived at the place, a group of people walked up the mountain quickly. Tao Lu walked a little behind, walking and saying: "I originally considered letting Jiang Yuan let go of his hands and feet, calmly investigate the scene, and then deploy resources to restart the war. I never dreamed that Old Nine would engage in any worship... I am now worried that it was done by villagers nearby, so I was happy for nothing."

"Even without this worship activity, checking along the social network is also the correct direction." Liu Jinghui smoothed his hair: "Since Jiang Yuan said it is suspected, the possibility is still relatively high."

Liu Cheng, who was next to him, said: "There are not many people in the nearby villages, and there is no cemetery nearby. However, we sent people to visit to see if anyone was buried here."

Many villagers in many places will quietly bury them, but in the capital, this situation is relatively rare. Liu Cheng is also just in case.

Tao Lu nodded. This kind of basic operation did not need him to arrange.

Walking until they started to sweat slightly, the place where the corpse was buried arrived. From a distance, they could see the cordon, and there was a drone flying in the sky. This is also a resource that Ningtai County does not have. The Zhengguang Branch will engage in it if they point to someone, and the county will be too lazy to use it even if they buy it.

Close by, Jiang Yuan was wearing a white coat and rain boots, busy in a corpse pit.

Several bottles next to him were filled with small things like insects and insect eggs.

"The corpse has been sent away. I made a rough check, the corpse is close to skeletonization, but there are still clothing fragments, and the victim's personal belongings include keys, accessories, mainly metal materials... The worship point is a little further ahead, and there are colleagues guarding it..."

Jiang Yuan said a few simple words, and also let Tao Lu and others see for themselves.

Tao Lu went over to see it and was immediately much more at ease.

The worship point is on the inside of the road. The surroundings are all secondary forests. Looking at the thickness of the trees, they are all at least 20 or 30 years old. Normally, there should be no tomb under it.

"Can the identity be confirmed? Can DNA and fingerprints be taken?" Tao Lu immediately turned back and asked Jiang Yuan: "Must be compared clearly with the victim confessed by He Wei."

"DNA should be no problem. As for fingerprints, the skin on the hands is gone. I don't know if it can be taken on the keys." Jiang Yuan said it quite easily. These are simple tasks. Anyone with LV1 can do it, and LV2 can do it very well.

It was Liu Jinghui and Li Haochen who, after determining the worship point, started screening along the victim's interpersonal relationships on the spot.

Although there is no complete and detailed list, a person's major interest relationships are limited, and love, hate, and hatred are also limited.

Liu Jinghui has been a criminal policeman for so many years. Seeing the identity of a victim, he can think of several vulnerable relationships in his mind. Most cases can basically be matched.

Such as husband and wife relationship, debt relationship, husband and wife partners, stealing men and women...

If it is a bit troublesome, it is the intimate relationship that has been accumulated for many years, but for the criminal police, they don't care so much. When they encounter such vicious cases, they must check all intimate relationships.

Therefore, some people deliberately design cases, hoping to keep themselves out of the matter, and some even design quite cleverly, which is really not understanding the judicial system deeply enough. Criminal police solve cases, mostly by force, and few people will really seriously break it for a long time, just to exclude a few suspects from the list.

Liu Jinghui is similar. He can make a very exquisite case-solving process, but it is not necessary.

Just with the current police force configuration of the Zhengguang Branch, compressing the list is equivalent to compressing the opportunity for young people to make contributions, which is an immoral act.

Even a middle-aged brigade leader like Cui Qishan volunteered: "Should I take people to sweep the woods here?"

"That... alas, sweep it." Tao Lu agreed reluctantly.

Just treat it as cleaning up. With more workload, at least clean it up.

Jiang Yuan finished the autopsy and it was almost the next day.

By the afternoon, Jiang Yuan woke up and returned to the task force. He saw a long list hanging in the large conference room of the task force, and then it was being XXed, marked with check marks, marked with stars...

"How is it? Is the progress smooth?" Jiang Yuan knew this was repeated screening. Using the words once said by Xu Ke, it belongs to the family background being too thick, and it is burned because of money.

Liu Cheng was sweating all over his head, but his mood was good, saying: "The relationships around the victim have been touched by us almost once. However, there is no clear suspect at present, just listed some suspected criminal suspects..."

"What did Liu Chu say?" Jiang Yuan asked.

Liu Cheng looked at Liu Jinghui and Li Haochen not far away and said: "Liu Chu and the others are also discussing quite fiercely. It's a collision of different theories."

It's just that each holds his own opinion and can't talk about it.

Jiang Yuan understood, then looked at the list posted on the whiteboard, and asked: "Didn't bring people over to ask?"

It seems that some people are flirting on the Internet, dancing with eyebrows, but when they reach the offline, they are low-headed and muffled. The criminal suspects who hide their heads and show their tails are not terrible. Pulling them over and asking them one by one, the suspects might jump out themselves.

Liu Cheng shook his head and said: "The total is still a bit large. Currently, there are at least a few people left as suspects. This victim Liu Zhiwu is a project manager of a decoration company. He has done many projects, and there are many situations of blacking people. There are many people with interest entanglements. Tao Branch means that at least we have to get some evidence before we can arrest them. Otherwise, once the other party destroys the evidence, this case will be ugly."

It can only be said that different people have different concerns in different positions.

The mastermind behind the scenes is relatively difficult to prove. If Old Nine can handle the evidence cleanly, the subsequent prosecution stage will be very ugly.

"Used footprints to screen, and only a few people left?" Jiang Yuan asked.

Liu Cheng said hurriedly: "We relaxed the weight a bit, just thinking that over a year, the weight might change. Other means are about to be exhausted."

Jiang Yuan immediately said: "If there are only a few people left, it is not many for footprints. Why don't you ask them for footprints, and I will compare them one by one. Proving the same, basically you can determine the suspect."

"Can it still be like this?" Liu Cheng's footprint identification, most of which can only reduce the scope, and the situation of directly identifying the same is very rare."

Jiang Yuan just nodded. He had rested enough and could open the temporary +1 state at any time. The application scenario of footprint identification was immediately expanded! ===== CHAPTER 664 =====
