Jiang Yuan automatically and consciously began to change into protective clothing and was ready to continue working.
Two corpses and one corpse are two different concepts.
In the domestic environment, a corpse is a normal homicide. In Ningtai County, if a corpse appears, first the director of the county bureau and the executive deputy director in charge of criminal investigation will appear, and the entire criminal police team will be dispatched.
and report to the Municipal Bureau.
When the municipal bureau has resources, it will often provide certain support, such as laboratory support and fingerprint support. If there are many forensic doctors, they can also send a forensic doctor to help with the autopsy.
But if two corpses appear, the case will directly rise to the level of knowledge of the provincial department.
If it goes well, that's it. If it doesn't go well, the provincial department will soon send a supervision team or technical experts to help.
Therefore, if a person accidentally kills another person, his skills in evading detection may still be effective. But if he kills two people at once, such as a young couple, a young couple, etc., the case will be
You will receive direct care from provincial experts.
At that time, the fingerprints, footprints, bloodstains and even imaging data at the scene may all be supported by the provincial technical department.
To sum it up, if you kill one person, the detective you face is completely different from two people.
And some murderers are extremely vicious and commit mass murders, killing all three members of the victim's family. Such murderers face the attention of ministerial-level criminal investigation agencies and personnel.
Sometimes, fingerprints that cannot be extracted at the grassroots level can be easily extracted by sending them to the laboratory of the ministry.
As for the task force and police officers, their attitudes towards cases of different levels are completely different.
Apart from anything else, if another corpse were to be found now, Xu Taining would not even have to consider going back, he would have to make something out of this case.
Judging from the current situation, the possibility of a third corpse appearing again is extremely high.
The newly excavated body bag was put back into a new body bag, and the forensic doctor put half of his body in the basket, half-carrying the bag of corpses, and carried it to the top of the mine.
The quality of the travel bag is not particularly good, and no one dared to lift it up after it had been buried underwater for who knows how long.
The bottom of the hanging basket is not flat, but has a mesh steel grille. Forensic doctors are worried that the hanging basket will damage the body, even the body that has been dismembered. At this time, everyone can look for clues.
That's it.
When the gondola was raised, several forensic doctors rushed forward and loaded the body bag onto a flatbed truck, and then prepared to transport it directly to Qinghe City for autopsy.
As for the cow forensic doctor, he was covered in filth and was only pulled up in the end.
Jiang Yuan was still hesitating whether to follow the corpse, but Wang Lan had already stopped him.
"Jiang Yuan, let's do the on-site investigation first." Wang Lan said in front of the leader: "Jiang Yuan's on-site investigation is one of the best among forensics. We can let others do the autopsy first and look at it later."
Forensic doctors also need to conduct on-site investigations, especially in this environment. There is a big difference between the on-site investigation done by forensic doctors themselves and the on-site investigation done by investigators.
Jiang Yuan had no objection and nodded: "Then I'll go down."
"Thank you for your hard work." Xu Taining rarely found time to say words of comfort.
Jiang Yuan smiled and followed Wang Lan down to the bottom of the mine.
After about 10 hours of work, the silt in the mine was almost cleared, and a few large concrete blocks were pulled up by hook machines and other equipment.
The Komatsu excavator, which was about the same size as a donkey, was humming and digging into the garbage.
The tens of meters of water above were pressing down, and the garbage became porcelain solid, and the boards seemed to be integrated into one body. It was also very laborious to dig out.
When Wang Lan saw Jiang Yuan coming down, he reassigned the area to him and whispered in a low voice: "Do you think the corpse here was made by Wang Guoshan?"
Wang Guoshan, the murderer of the corpse dumping case in the reservoir, was confirmed to have killed more than 10 people, but his explanation of previous cases was very vague.
Regarding the case involving Zifeng Mountain, Wang Guoshan has been vague from beginning to end. This is one of the reasons why Liu Jinghui believes that it is necessary to continue the investigation.
It was difficult for Jiang Yuan to be sure at this time. He could only say: "Whether it was Wang Guoshan who did it or not, he must have accomplices outside."
"You mean the one who poked the tires?" Wang Lan suddenly remembered.
"right."
"Perhaps the person who punctured the tire was just an accomplice in one or two cases?" Wang Lan has encountered similar cases.
There is a fundamental difference between murderers who kill multiple times and serial killers described in Europe and the United States. Many murderers kill for some kind of profit relationship.
In this case, the murderer will have the possibility of temporarily finding an accomplice. It is almost similar to the concept that the enemy of my enemy is my friend.
But after the temporary alliance ends, some murderers will continue to kill, while others will struggle with keeping secrets their entire lives.
In comparison, cases like this are naturally easier to detect.
Jiang Yuan knew what Wang Lan meant and what kind of answer she expected to hear.
But Jiang Yuan still shook his head and said: "It won't be a novice. I have carefully studied the case of Liu Chu's tire being punctured. The prisoner acted very decisively and was brave and careful. If it weren't for Liu's luck,
He might have died in a car accident at that time."
After a pause, Jiang Yuan continued: "If the car accident caused a fire, or the location of the car accident was more in line with the murderer's expectations, and he set a fire again, the tire case might not even exist."
Wang Lan nodded slowly: "So, the other murderer is still the main criminal?"
"Wang Guoshan is still in prison. He can commit crimes again independently or by gathering others." Jiang Yuan said here, "But if I were asked to do this case, I would not associate it with Wang Guoshan."
together."
"Oh? Why?" Wang Lan was a little surprised. Merging cases is often the best way to solve cases.
"Liu Chu should have considered merging the case. He also failed to solve the case in a short time." Jiang Yuan's answer was also very simple.
Since arriving in Zifeng Town, Jiang Yuan has consciously chosen a different focus from Liu Jinghui.
In Jiang Yuan's impression, Liu Jinghui's reasoning ability is still very strong.
He had been working on the case for a month but couldn't solve it. If he followed his path again, even if he didn't consider the problem of secretly uncovering the murderer or being reminded to correct himself, Liu Jinghui couldn't wait for another one.
It’s been months.
If it was just to solve this case, then Jiang Yuan felt that it would not be too late to wait a few more months before taking up the case again.
The most urgent thing at the moment is to find Liu Jinghui's whereabouts.
It is better to see people or corpses than to disappear.
Furthermore, Jiang Yuan and Liu Jinghui took different paths. He only had to follow the evidence.
Merging cases tests precisely the ability of reasoning and analysis.
This itself is not what Jiang Yuan is good at.
Wang Lan partly understood Jiang Yuan's thinking, but he didn't completely agree.
However, the person in charge of this case is Xu Taining, and it is not the turn of the two forensic doctors to direct the direction of the case.
The two ended their conversation and continued digging into the mine.
More and more garbage and construction debris are being dug out.
Towards evening, another SANY mini excavator was delivered, and the progress was slightly accelerated.
Then, another gray plastic bag was dug out.
"Wait a moment. Don't take it out." Jiang saw it from a distance and walked over quickly.
When the last body bag was dug out, no one was sure it contained a corpse. Needless to say, this time everyone could guess it.
Someone took photos. Jiang Yuan looked at the body bag and the surrounding garbage, calmly analyzed it, and said: "Take photos of the garbage as well, and confirm the location."
Wang Lan quickly woke up and said hurriedly: "Yes, the garbage should be landfilled in the same batch. It can also help analyze the source of the corpses."
They haven't seen the body yet, but the news from the rear, although the body provides a lot of information, is not necessarily helpful in determining the source of the body.
In fact, it is very, very difficult to identify the origin of corpses that have been dead for many years. However, the proportion of corpses whose origins can be identified is extremely small.
There is no data on the identification rate of criminal cases, but the difficulty of identifying the source of corpses can be seen from another aspect - some areas have famous mass graves, and extremely powerful anthropology experts are sent into them to identify the source of corpses.
It is still a specific group of people in a known area, and the recognition rate is still not high.
For the forensic doctors present, anything that can improve the identification rate is helpful.
Jiang Yuan even changed his gloves on the spot, added two more layers, and started sorting out the garbage on the spot.
A previous case involving an old man working as a scavenger allowed him to obtain garbage classification (LV4), and now he can use it very efficiently.
Although the forensic doctors nearby also have certain abilities in identifying evidence, they gradually waited in front of Jiang Yuan as they watched Jiang Yuan's movements.
