Chapter 542 The First Scene
late at night.
In the conference room of the Luojin City Bureau, the lights were still on.
dong dong.
Pang Jidong knocked on the door and went straight in. He saw Yi Shihuang and his disciples flipping through the files at the table.
"Aren't you going back yet?" Pang Jidong asked with a smile.
Yi Shihuang looked up, and the wrinkles on his face shook: "It's too late to go back. If I wake up my wife will be scolded again, I might as well sleep in the office. Don't you have to go back too?"
"I'm planning to go back. My wife loves you." Pang Jidong dazzled and asked, "What are you busy with? Is something wrong with 828?"
"No."
"Then why worry. You save a lot of time in the investigation stage, and you have plenty of time to handle the case."
"Hey, I'm here to see...how this case was solved." Yi Shihuang pushed the documents in front of him, and said, "We can't let these technologists have the final say in the future."
When he said this, Pang Jidong's expression also became serious, and he said after a while: "Anyway, didn't we get the fingerprints back?"
"Now fingerprints are taken by professional on-site inspections." Yi Shihuang glanced at Pang Jidong and said, "We are the ones who arrest people."
"En..." Pang Jidong rubbed his face: "It's too late, I'm all confused, I don't have enough brains."
Yi Shihuang sighed: "Insufficient brain is a big problem, now is not the age of iron feet."
"The young people today are different from us. They all know a little bit of technology, and there are more and more college graduates." Pang Jidong said, he sat down at the table naturally, looked at the information, and asked: " If you don't engage in technology, what are you going to do with this case?"
"Isn't that what I was thinking about tonight. First of all, I must look for witnesses. They may not have seen it, but they may have heard it." Yi Shihuang did not answer directly, and silently flipped through the materials. After a while, Said: "As for the fingerprint, we actually asked Li Tong to look at it, and we couldn't compare it at that time."
"Was the suspect in Curry at the time?"
"The old poisonous insect is still released after serving his sentence, why is he not here?"
"Li Tong should be quite strong..." Pang Jidong said, suddenly snorted, smiling like a cute old man: "Do you think Li Tong will doubt himself when he hears this story? I didn’t sleep, so I just looked at this fingerprint all night.”
"He won't." Yi Shihuang said.
Pang Jidong said unexpectedly: "Are you so sure?"
"I called and asked." Yi Shihuang's expression was innocent like a Shar Pei dog.
Pang Jidong was stunned: "Sprinkle salt in your wound, are you not planning to use others anymore?"
"I'm about to retire anyway. However, Li Tong's mood is okay, at least better than us."
"How to say?"
"He said that Jiang Yuan used image enhancement or something, it was a picture detection thing, and it was very high-end. He couldn't do it, so it had nothing to do with us."
"There are quite a lot of new things." Pang Jidong was quite acceptable, and when he turned his head to see Yi Shihuang still looking through the files, he just smiled.
In fact, technology has been innovating all the time. You don't need to wait for Jiang Yuan to come over. In the past few years, there have been countless cases solved by using mobile phones alone.
In the past, there were many troubles in borrowing the means of technical investigation, and it was not used in ordinary small cases.Now that the Internet Security Brigade has been established, many cases have been solved by scraping WeChat records.
As for techniques such as trace physical evidence, the coverage of the case is also very wide, and the effect is excellent, but the police have always been reluctant to publicize this aspect.
"Okay, don't think about it too much. In fact, let alone our people who solve crimes. Now there are fewer people who are willing to do crimes. Professional criminals are all engaged in telecom fraud. They don't have any skills, and they can't even find people. "Pang Jidong put down the file and went home to find his wife.
Unmoved, Yi Shihuang continued to study the file with his head bowed.
He is not going to solve all the cases, but he can solve the remaining half or one third.
……
Jiang Yuan stayed in the trace evidence laboratory for three days.
The pollen is not so easy to manipulate, and the amount is too large, one by one, the backache and neck pain of the really tired people.
Jiang Yuan suddenly understood the problem of the popularization of forensic botany. The root of the difficulty in popularization lies here. Few high-level botanists are willing to do this job for criminal investigators.And it's useless if the level is not high.
There is no need to kidnap morality. Forensic investigation is important, but paleontology is equally important. It is more meaningful to explore the origin of human beings.
If you want to say, to explore an ancient tomb or ancient building complex, you can at least write a few papers. If a young man who has just graduated goes to a university, he will leave after five years, sweeping ancient tombs, at least he can keep his own. Work.If you want to solve a case for the police, you may leave nothing but thank you.
—unless the case is super important.
On the fourth day, Jiang Yuan called Pang Jidong and his four brigades and set off for the area where the first case occurred.
This is a very quiet residential area with luxuriant vegetation and numerous residential areas. The roads are generally not wide, suitable for pedestrians, and there are relatively few cars.
Almost there, Pang Jidong introduced: "This is the wealthy area of our Luojin area. There are many villas, many bungalows, and almost no high-rise buildings. There are a few high-end hotels, and then there are schools, small business districts, large shopping malls and There are no such things as office buildings, and it is a relatively pure place to live, which is very popular with us Luojin people, and the housing prices are higher than those in the surrounding areas."
This is something that will not be written in the dossier. Jiang Yuan realized the main point and asked: "So when the case came out, it attracted a lot of attention?"
Pang Jidong said: "Well, but generally speaking, the middle class can afford to live here, and the rich are also willing to live here. It should be a very safe area. In fact, we have a guess, because there were surveillance cameras around the area. Yes, there is always a risk of exposure for vehicles entering and exiting, and we guess that the murderer should also live in this area."
Jiang Yuan was noncommittal, this kind of reasoning can be regarded as reasoning, but it is not very rigorous, compared with Liu Jinghui's reasoning, it is not competitive, it is more like a guess.
Pang Jidong continued: "The problem is that there are a lot of people living here, 10,000+, there are always 20 people, and the area is actually large. Many communities are very remote, because only people from their own community come and go, and there are few passing cars. The more lively places are near the school, and in front of a small supermarket.”
"So the crime scene could be anywhere?" Jiang Yuan understood what he meant.
Pang Jidong nodded: "Before this case, some schools had school buses, and some schools allowed students to walk home or ride bicycles home. It is normal for middle school students to walk home by themselves. , After a short drive, you may arrive at a remote place. After the violence, drive a certain distance, and it is possible to drive back to your home.”
This is also conjecture, Jiang Yuan listened silently.
Mu Zhiyang, who was sitting with him, said at this time: "Ordinary rapists run away after finishing. Why did this person take the risk to do it twice?"
This is the question that everyone who sees this case will ask.Second rape cases are extremely rare, and many people have never heard of them.
Pang Jidong said: "Maybe it's because of stimulation. If it's possible, there is a psychological problem?" Pang Jidong paused, and said: "We have been engaged in criminal psychology for a while, which is the profile of the FBI, an expert from the provincial department. Helped, but no one was caught. His definition is that the criminal has impotence and may need to be hardened under special circumstances. The first time, it is to relieve pressure and also for stimulation."
Pang Jidong paused, and then said: "The second time, we guessed that it was probably at the criminal's place, home, or rented place, and the criminal might have given himself medicine. We estimated the time based on the four victims, I also ran a map, but it didn't work..."
"It won't be at the criminal's house, at least not at a fixed location." Jiang Yuan has been silent, and he is very sure at this time.
Pang Jidong had been involved in the Erqiang case for a long time, and he didn't dare to categorically say such a conclusion, so he couldn't help asking: "Why not a fixed location."
"The types of pollen contaminated by the clothes of the four victims are quite different, and the proportions vary greatly, so it is not in a fixed building." Jiang Yuan has been collecting pollen for several days. After coming down, I also had my own analysis of the case.
Pang Jidong could only nod his head. He was assisting Jiang Yuan this time, so he naturally followed his train of thought and said, "That's four cases, choose eight locations?"
"Yes." Jiang Yuan's answer was completely different from the previous conjecture of the task force.
"Go to the location marked A immediately." The driver reminded at this time.
Soon, the car stopped on the side of a small road by the river.
The flow of the river is very slow, and it looks like a stagnant water from a distance.There is a sign on the side of the road, named Yongtongqu.
Jiang Yuan got off the car and walked slowly along the path.
Pang Jidong followed him closely.Several criminal policemen in another car also got out of the car and looked around.
This place is about a few hundred meters away from the place where the first victim was shocked. It is still very remote, and the greenery is very beautiful. The big trees on the side of the road are luxuriant, the trees are full of green grass, and the half-person-high bush.
"It should be here." Jiang Yuan suddenly stood in front of a lawn, took a photo with his mobile phone, then sighed, and said, "Ask the management staff of the greening here. If it's overly refurbished."
"I'll ask if the municipal government is in charge, or if it's a nearby property." Pang Jidong had already found someone, so he called right now.
Jiang Yuan stretched out his hand to signal.
Mu Zhiyang immediately brought him gloves, headgear and footmuffs.
Jiang Yuan slowly put it on.
They were standing about 20 meters away from the river, next to a two-lane asphalt road, and next to a bicycle lane without bicycles.
The crime scene identified by Jiang Yuan was next to a thick sycamore tree, covering a large area of shade.
The lawn under the sycamore tree is about three to four meters wide. The bushes on both sides have two layers, one high and one low.
Jiang Yuan could imagine that if the perpetrator brought the victim here, pushed him into the lawn, and then got down on his stomach, the bushes could basically cover his figure perfectly.
As for shouting... as long as the victim opens his mouth to speak, he will be shocked, and the perpetrator obviously doesn't care whether the victim is awake or dead...
In the words of experts in criminal psychology that Jiang Yuan saw in the file, this is a kind of extreme control.The perpetrator wants to do the most offensive and offensive behavior in this kind of place that is close to the public.
Similarly, there are photos of the location of the first victim who was shocked four times in the dossier.
For an ordinary person, these four electric shocks are enough to be fatal.
It can be said that this is more violent than ordinary punching and kicking.
If possible, such a person should be sent to the underworld as soon as possible.
Jiang Yuan was fully dressed, and bent over to search nearby.
After more than a year, ordinary biological inspection materials should not be available, and now we will see if it is possible to find the items that the perpetrator or the victim lost unintentionally.
Pang Jidong asked someone, and then reported back to Jiang Yuan, who also helped find him.
Jiang Yuan found a size of about [-] square meters, stopped, shook his head and said: "It seems that there is nothing left, mark it, let's go to the next point."
Pang Jidong did as he did, walked a few steps, then stopped suddenly, looked back at this place, still a little uncertain: "So, we have already found the first scene of the No.1 victim?"
"Correct."
"Let's go like this?" Pang Jidong was a bit reluctant. If the investigation team really found the victim's first scene, why not dig three feet?
Jiang Yuan only said: "There are still seven places, or just leave two people to take a look."
When Pang Jidong heard this, he kept two people around and told them to walk around to see if they could find any witnesses. At the same time, he called someone again.
As an old criminal policeman, Pang Jidong knew that if he could find all eight scenes, various clues would naturally come out of this case.
