Chapter 691 Screening
The footprints of worshipers that Jiang Yuan found near the burial site were not surprising in themselves. He is average in height and age, slightly light in weight, but he is also an ordinary weight in the tens of millions, which cannot directly point to Lao Jiu's identity.
However, the act of paying homage exposes much more.
This shows that there is an emotional relationship between Lao Jiu and the buried deceased, regardless of grudges or human suffering. In short, the act of worshiping completely drags the case from a serial murder to an ordinary murder.
The most terrifying thing about a serial killer is actually his anti-social nature. If he is a serial killer who has no desires or desires, he will be the most helpless. Most of the serial killers who do whatever they want are very difficult to detect. Even if the police are connected to his Brain circuits may not be able to effectively conduct investigations.
Love killings are much better. Although a person seems to know many people, in fact, the social limit of normal people is 500 people, and the number of people who can maintain communication is about 150. This is the so-called Dunbar's 150 Law.
From the perspective of the criminal police, it is impossible for all of these 150 people to be enemies.
Naturally, there are even fewer people who can create love and hatred to the extent that they need to kill people.
Therefore, after hearing Jiang Yuan's discovery, the criminal police officer who often handled cases could easily come up with eighteen ways to solve the case in his mind without Liu Jinghui's reminder.
Tao Lu went directly to the scene by car.
Liu Jinghui, Li Haochen, Cui Xiaohu and others accompanied him all the way.
When they arrived at the place, a group of people walked up the mountain quickly. Tao Lu walked a little behind and said as he walked: "I originally considered letting Jiang Yuan free his hands and feet, and surveyed the scene with peace of mind, and then allocated resources and restarted It’s a big battle. I never dreamed that Lao Jiu would actually hold some kind of sacrifice... Now I’m just worried that it’s the nearby villagers and the like, so I’d be happy in vain.”
"Even if there is no such worship event, following the social network to check is the right direction." Liu Jinghui stroked his hair and said: "Since Jiang Yuan said it is suspected, the possibility is still relatively high."
Liu Sheng next to him said: "There are no people in the nearby village, and there is no cemetery in front of it. However, we sent people to visit and see if anyone is buried here."
Villagers in many places would bury people quietly, but in the capital, this situation was relatively rare, and Liu Sheng was just in case.
Tao Lu nodded. He didn't need to arrange this basic operation.
As I walked, I started to sweat slightly, and I reached the place where the body was buried. You can see the cordon in the distance, and there is also a drone flying in the sky. This is a resource that Ningtai County does not have. Everyone in the Zhengguang Bureau can do it, but the county is too lazy to use it even if it buys it.
Nearby, Jiang Yuan, wearing a white coat and rain boots, stood busy in a corpse pit.
Several bottles nearby contained small things such as insects and insect eggs.
"The body has been sent away. I did a general inspection. The body is close to bones, but there are still pieces of clothing. In addition, the victim's belongings include keys and accessories, mainly made of metal... Go to the place of worship. If you walk a little further, there are colleagues guarding you..."
Jiang Yuan said a few words briefly and asked Tao Lu and others to see it in person.
Tao Lu went over to take a look and immediately felt relieved.
The worship point is located on the inside of the roadside. There are patches of secondary forest nearby. Judging from the thickness of the trees, they are at least twenty or thirty years old. Normally, there should be no tombs underneath.
"Can the identity be confirmed? Can the DNA and fingerprints be obtained?" Tao Lu then turned back and asked Jiang Yuan: "We need to compare it with the victim He Wei told us."
"The DNA should be fine. As for the fingerprints, the skin on the hands is gone. I don't know if I can get it from the key." Jiang Yuan said it quite easily. These are simple tasks that anyone with LV1 can do. , LV2 can do very well.
On the other hand, Liu Jinghui and Li Haochen, after confirming the memorial site, began to screen the victims based on their interpersonal relationships.
Although there is no complete and exhaustive list, the major interests that a person can be involved in are limited, and so are the love and hatred.
Liu Jinghui has been a criminal police officer for so many years. When he sees the identity of a victim, he can think of several vulnerable relationships in his mind. In most cases, he can basically match it.
Like the relationship between husband and wife, the relationship between debtors, husband and wife partners, cheating men and women...
To say that it is a bit troublesome, it is the kind of intimate relationship that has been resented for many years, but for the criminal police, they actually don't care how detailed it is. When encountering such a vicious case, they must investigate all the intimate relationships.
Therefore, some people deliberately design cases in the hope of keeping themselves out of the case. Some even design cases quite cleverly, but they really do not understand the judicial system deeply enough. When criminal policemen solve cases, they usually try their best to get rid of them ten times at a time. Few of them will really work hard for a long time just to exclude a few suspects from the list.
Liu Jinghui is similar. He can make a very sophisticated crime-solving process, but it's not necessary.
With the current police configuration of the Zhengguang Bureau, if you reduce their orders, it is equivalent to reducing the opportunities for young people to make meritorious deeds, which is an unethical act.
Even a middle-aged captain like Cui Qishan volunteered and said, "How about I lead some people to sweep away all the woods here?"
"Then...well, let's sweep it." Tao Lu reluctantly agreed.
Just think of it as cleaning, do more work, and at least clean it more cleanly.
It was almost the second day after Jiang Yuan completed the autopsy.
In 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 people kept being fucked, marked with numbers, and asterisks...
"How's it going? Is it going well?" Jiang Yuan knew that this was a repeated investigation. According to what Xu Krypton once said, it was because the family had too much money and burned it.
Liu Sheng was so busy that his forehead was covered with sweat, but he was in a good mood. He said: "We have almost touched the relationship around the victim. However, there is no clear suspect yet, but some suspected crimes have been listed. The suspect comes out..."
"What did Liu Chu say?" Jiang Yuan asked.
As he spoke, Liu Sheng looked at Liu Jinghui and Li Haochen not far away and said, "Liu Chu and the others were also discussing quite intensely. It was a collision of different theories."
It's just that everyone has their own opinions and can't come to an agreement.
Jiang Yuan understood, looked at the list posted on the whiteboard in front of him, and asked, "Didn't you bring the person over for questioning first?"
It's like some people are flirting online and are very happy, but when they go offline, they lower their heads and keep quiet. The suspects who hide their heads and tails are not scary. If you pull them over and ask them one by one, the suspects might jump out on their own.
Liu Sheng shook his head and said: "The total number is still a bit high. The remaining suspects are at least a few older people. The victim, Liu Zhiwu, is a project manager of a decoration company. He has done a lot of projects and is undercover. There are many people's situations, and there are many people with entangled interests. Tao Zhi means that at least some evidence must be obtained before arresting, otherwise, once the other party destroys the evidence, the case will be ugly."
It can only be said that different people in different positions have different concerns.
It is difficult to prove the mastermind behind the scenes. If Lao Jiu can clean up the evidence, the next stage of prosecution will be very ugly.
"Sifting through the footprints, are there only a few people left?" Jiang Yuan asked.
Liu Sheng said hurriedly: "We have relaxed the weight a little, just thinking that in more than a year, the weight may change. Other methods are almost exhausted."
Jiang Yuan immediately said: "If there are only a few people left, it's not a lot of footprints. If you don't ask them to get the footprints, I will compare them one by one. If they prove to be the same, the suspect can basically be identified."
"Is this still possible?" Most of the footprint identifications that Liu Sheng came into contact with could be reduced in scope, and there were very few cases where they were directly identified as the same. "
Jiang Yuan just nodded. He had rested enough and could turn on the temporary +1 state at any time. The application scenarios of footprint identification were immediately expanded!
