Jiang Yuan slept for a few hours before being woken up by a phone call. He got into the car and headed to the Qinghe Municipal Bureau for a meeting.
The first floor of the City Bureau is the lecture theater where he gave a speech before. Going further inside is the conference room where he will go this time.
The conference room was much smaller than the lecture theater, and could only accommodate a total of twenty or thirty people. However, the director, deputy director, and captain of the criminal police detachment of the municipal bureau and others all came, and the atmosphere was extremely...
Serious.
Jiang Yuan was a little groggy. He followed Wang Lan and sat in the corner of the conference room. Looking at everyone, he couldn't help but think: In a primitive tribe, this would be equivalent to the inexplicable death of the tribe's members. From the chief to the sacrifice, everyone
And attended the bonfire party.
"Why are you sitting so far away?" Liu Jinghui moved directly from the conference table to Jiang Yuan.
Although a few people turned to look over, they all quickly turned away. The fourth-level senior police sergeant from the provincial department and the junior forensic doctor from Ningtai County had little impact on the municipal bureau.
The police department is a relatively independent department. At the level of the municipal bureau and the provincial department, if you are not doing cases, you are still relatively comfortable and free. You don't need to worry about the provincial department and the like.
In fact, Jiang Yuan didn't need to care about the opinions of the city bureau people. He just leaned on his chair and said a little listlessly: "It's not my turn to sit in the front row. We stayed up too long yesterday."
The word "boil" was a pun, which made Wang Lan next to him laugh.
Liu Jinghui also knew this forensic doctor from Qinghe City and looked at him with some confusion.
"We were deboning the corpse yesterday." Wang Lan completed this hellish joke.
What Liu Jinghui is best at is reasoning. As soon as he thought about it, he was immediately disgusted.
"You forensic doctors..." Liu Jinghui was considered well-informed. He shook his head and asked Jiang Yuan: "How do you feel about the case?"
Although the case analysis meeting was next, Liu Jinghui was more concerned about Jiang Yuan's thoughts.
He can be regarded as an old detective who has been running around the province for 10 years. He has met local strange people and professional players supported by ministries and commissions and other provinces and cities. But no matter from which angle you look at it, Jiang Yuan's skills and
Judgment is at T1 level.
There are people of the same level, but obviously not in the Qinghe Municipal Bureau.
Jiang Yuan patted his head, thought for a while, and said: "I think these six corpses have been dealt with relatively cleanly, especially the last two, which have been upgraded very thoroughly. I don't know how he will deal with the rest.
My brain is gone."
Liu Jinghui didn't expect Jiang Yuan to consider it from this perspective, and couldn't help but said: "How to deal with the head, does it matter?"
"Compared to other parts of the body, the head is still more difficult to deal with." Jiang Yuandao: "The skull is the hardest, so it is not easy to cut. It might be better to smash it with a hammer. In short, if there is a way to deal with the head, it can be done.
Dealing with other parts of the body.”
"What do you mean?" Liu Jinghui wasn't sure if he understood.
Jiang Yuandao: "I looked at the places where the bodies were dumped in the reservoir. There are roads nearby. I suspect the murderer drove to the road, then transported the bodies there and then abandoned them. Normally, he would not dig alone again.
Just bury the body in a pit."
"Well, the murderer must be very strong. It is possible to use a non-motorized vehicle or even carry the body directly." Liu Jinghui told Jiang Yuan his judgment.
Jiang Yuan was a little surprised: "The body bag is very heavy. When we carried it to the autopsy table, it was easy for four people and difficult for three people."
"It takes four people to lift a pig during the New Year in rural areas." Liu Jinghui pointed it out, and then said: "The back can still be moved. We have done relevant statistics before. For corpses dumped at medium and short distances, the figures are based on people's backs and non-motorized vehicles.
host."
"Do you think the murderer lives near the reservoir?"
"At least he is familiar with the reservoir." Liu Jinghui said: "I went to the scene to see it, and also asked the local people who helped to retrieve the body. The murderer chose a very good place. If it hadn't been for this drought, he would not have been found under normal circumstances.
.”
"If you are very familiar with the reservoir, shouldn't you choose the deep water area?"
"This can be seen from two aspects. One is that the deep water areas are close to the center of the reservoir, so it is more difficult to transport the body by land. The other is that the murderer may not consider the situation of drying up because he is familiar with the reservoir. Because in
In his memory, the reservoir may not have been drought to this extent."
Jiang Yuan nodded slowly. Liu Jinghui's reasoning also made sense, and Jiang Yuan was not prepared to argue with Liu Jinghui in this regard.
"Another one. The murderer's subsequent body bag was found in deeper waters. This can also be seen as part of the escalation of the crime." Liu Jinghui paused and said: "I suspect that when he threw the body bag,
The problem of water flow has been taken into consideration, so the original dumping place needs to be reconsidered."
Jiang Yuan smiled unconsciously when he saw Liu Jinghui's big head.
One thing that is very difficult about criminal science and technology is that what you want to solve is a real problem, but the technology used actually comes from paper.
In other words, it is necessary to explain the real-life situation through paper and laboratory operations.
This is actually very difficult.
The reason why DNA and fingerprints are so widely used and so easy to use is because they are simple and straightforward and suffer less interference from reality.
Why are so few people using crime scene reconstruction and bloodstain analysis? It’s because their judgment processes are too complicated, and ideal things always happen less often.
When those who engage in economics write economic works, they must assume the concept of a "rational economic man", which requires people to be not only rational but also self-interested.
If those who work in the criminal department assume a "rational criminal", that would be purely insane - if people could be rational and self-interested, most of the cases would not have happened.
This is the most troublesome part for Liu Jinghui to engage in reasoning.
Without enough information, you can't even tell whether the murderer is a psychopath. A psychopath in the literal sense.
According to American profiling analysis, serial killers have more or less mental problems.
And the six corpses now are actually enough to give the other party this name.
Seeing Liu Jinghui's troubled look, Jiang Yuan's spirit relaxed slightly after a day of sleepiness.
So, Jiang Yuan decided to add another number to him and said: "Liu Chu, if we can't find the heads of No. 5 and No. 6, we have to consider expanding the search scope."
"That important?"
"No, I'm also trying to reason. If the murderer can eliminate all traces of the brain's processing, he should also be able to eliminate all traces of the body's processing."
Liu Jinghui was stunned for a moment before he understood what Jiang Yuan meant. He frowned and said, "Are you trying to say that there are more corpses and they have been disposed of separately?"
Jiang Yuan spread his hands: "Maybe, I have no evidence, just reasoning."
"Bullshit reasoning." Liu Jinghui felt unhappy all over. He usually used reasoning to disgust people, but he didn't expect that this time he would be defeated by Jiang Yuan.
This method of killing and not burying made Liu Jinghui's brain spin crazily.
In the end, he had to admit that if the murderer continued to upgrade and learn, it was really possible.
"Ahem. Everyone, be quiet." Shen Feihong, the criminal police detachment leader of Qinghe City, stood up and started the meeting process.
After announcing the establishment of the 724 Qinghe Massacre Case Task Force, Shen Feihong reported the situation of the case.
After receiving some information about the autopsy, Shen Feihong said: "Just two hours ago, our frontline police officers confirmed the source of corpse No. 1. Now, Captain Shi from the Serious Crime Brigade will explain it to everyone."
Jiang Yuan and Wang Lan were both a little surprised and became serious together.
Captain Shi is tall and thin, with protruding cheekbones, dark circles under his eyes, and yellow teeth. At first glance, he looks like the kind of driver who drives a taxi during the day, drives an online ride-hailing service at night, and runs Meituan while waiting for his shift.
Similar.
He took a piece of paper in his hand, wrote a few words on it, glanced at it, and said: "According to the information provided by the forensic doctor, deceased No. 1 was a female, about 40 years old, 170 cm tall, and had porcelain teeth installed.
… After finding no results for the missing persons in this city, we expanded the search scope to the entire province…”
"Finally, we requested the assistance of the provincial department and confirmed the identity of deceased No. 1 through mitochondrial DNA technology. The deceased's name was Ma Hongyan, a native of Wanxiang City. She was a buyer for Maolin Specialty Products Company in Wanxiang City. Eight years ago, she and
Colleagues from the company were on a business trip and separated in Changyang City to go to their destinations. Qinghe City was the second stop of Ma Hongyan’s trip..."
Jiang Yuan listened quietly in the corner, knowing that the task force was full.
Whether it is mitochondrial DNA technology or a province-wide search, it is very time-consuming in terms of manpower and material resources.
The breakthrough point was chosen as No. 1 because the characteristics of corpse No. 1 were more obvious. Facts have proved that the task force's choice was extremely correct.
But judging from the results, the identity information of No. 1 is not enough to promote the progress of the case. Instead, it illustrates the complexity of the case from another aspect. The disappearance case 8 years ago means that the murderer began 8 years ago.
