Chapter 515: First Scene

Late at night.

In the conference room of the Luojin Municipal Bureau, the lights were still on.

Thump thump.

Captain Pang Jidong knocked on the door and entered directly, only to see Yi Qin Shi Huang and his apprentice turning over the case files at the table.

"Not going back yet." Captain Pang Jidong asked with a smile.

Yi Qin Shi Huang looked up, the wrinkles on his face shaking: "It's too late to go back, waking up the wife and being scolded again, it's better to sleep in the office. Aren't you not going back either?"

"I'm ready to go back. My wife loves people." Captain Pang Jidong showed off and asked: "What are you busy with? Is there a problem with 828?"

"No."

"Then what's the rush. The time you saved in the investigation stage is huge, there is plenty of time to handle the case."

"Hey, I'm looking at... how this case was solved." Yi Qin Shi Huang pushed the information in front of him and said: "Can't let these technical people have the final say in the future."

As soon as he said this, Captain Pang Jidong's expression also became serious, and after a while, he said: "In any case, isn't the fingerprint still taken back by us?"

"Now taking fingerprints, there are professional crime scene investigations." Yi Qin Shi Huang glanced at Captain Pang Jidong and said: "We are the ones who go to arrest people."

"En..." Captain Pang Jidong rubbed his face: "It's too late, I'm confused, my brain is not enough."

Yi Qin Shi Huang sighed: "Brain not enough is a big problem, now it's not the era of iron soles."

"The young people now are different from us. They all know a little technology, and there are more and more college graduates." Captain Pang Jidong said, his body sat at the table naturally, then looked at the information and asked: "Without technical people, how are you going to do this case?"

"I was thinking about this tonight. First of all, it must be to find eyewitnesses. It's not necessarily seen, maybe heard." Yi Qin Shi Huang didn't answer directly, silently turning over the information, and after a while, said: "That fingerprint, we actually asked Li Tong to look at it, and it didn't match at that time."

"Was the suspect in the library at that time?"

"Old drug worm, and released from prison, how could he not be."

"Li Tong should be quite strong..." Captain Pang Jidong said, suddenly puffing, laughing like an old cute baby: "You say Li Tong heard this story, will he doubt himself? Maybe he didn't sleep all night tonight, just looked at this fingerprint all night."

"He won't." Yi Qin Shi Huang said.

Captain Pang Jidong was surprised: "You are so sure?"

"I called and asked." Yi Qin Shi Huang's expression was as pure as a Shar-Pei.

Captain Pang Jidong was stunned: "You sprinkle salt on the wound, are you not ready to use others anymore?"

"I'm retiring soon anyway. However, Li Tong's mood is okay, at least better than ours."

"How to say?"

"He said Jiang Yuan used image enhancement or something, it's something from the map investigation, and it's high-end. He can't do it, it has nothing to do with us."

"There are quite a lot of new things." Captain Pang Jidong could accept it, turned to see Yi Qin Shi Huang still turning over the case files, and just smiled.

In fact, technology has been innovating. No need to wait for Jiang Yuan to come. In recent years, I don't know how many cases have been solved by mobile phones.

In the past, borrowing technical investigation methods was a multi-layered hassle, and they weren't used for ordinary small cases. Now that the Cyber Security Brigade has been established, by digging through WeChat records, many cases are solved with ease.

As for technology like trace evidence, the coverage of the case is also very wide, the effect is extremely good, but the police are generally unwilling to publicize it in this regard.

"Okay, don't think too much. In fact, let alone the people who solve the case, there are fewer people willing to commit crimes now. Professional criminals all go to engage in telecom fraud. Without technology, they can't even find people." Captain Pang Jidong put down the case files and went home to find his wife.

Yi Qin Shi Huang remained unmoved and continued to study the case files.

He didn't intend to solve all the cases, solving the remaining half or one-third would be fine.

Jiang Yuan stayed in the trace evidence laboratory for three days.

Pollen is not so easy to handle, and the quantity is too large. Picking them out one by one is really tiring and makes people's waist and neck ache.

Jiang Yuan suddenly understood the popularization problem of forensic botany. The root of the difficulty in popularization lies here. There are not many high-level botanists willing to do this work for criminal investigation. And those with low levels are useless.

There is no need for moral kidnapping. Criminal investigation is certainly important, and paleontology is equally important. Exploring the origin of mankind is more meaningful.

To say the least, exploring an ancient tomb or an ancient building complex can at least write a few papers. If a young person who has just graduated goes to a university, he must be promoted or leave in five years. Sweeping ancient tombs can at least keep his job. Wanting to solve a case for the police, maybe except for thank you, nothing will be left.

—Unless the case is super important.

On the fourth day, Jiang Yuan called Captain Pang Jidong and his Fourth Brigade and set off for the area where the first case occurred.

This is a very quiet residential area with lush vegetation, many communities, and roads that are generally not wide, suitable for pedestrians, and few cars.

Almost at the place, Captain Pang Jidong introduced: "This can be considered our Luojin's rich area. There are many villas, many foreign-style houses, and almost no high-rises. There are a few high-end hotels, and then schools and small business districts. There are no big shopping malls and office buildings. It can be considered a relatively pure residential area. It is quite popular with our Luojin people, and the housing prices are higher than the surrounding areas."

This is something that will not be written in the case files. Jiang Yuan experienced the key points and asked: "So when the case comes out, it is very concerned?"

Captain Pang Jidong said: "It can be considered so, but generally speaking, the middle class can afford to live here, and the rich are also willing to live here. It should be an area with very good public security. In fact, we have a conjecture, because there was monitoring around the area at that time, the vehicles entering and leaving always had the risk of exposure, we speculate that the murderer should also live in this area."

Jiang Yuan didn't commit himself. This can also be considered reasoning, just not very rigorous. Compared with Liu Jinghui's reasoning, it has no competitiveness and is more like a conjecture.

Captain Pang Jidong continued: "The problem is that there are many residential populations here, ten or twenty thousand people are always there, and the area is actually large. Many communities are very remote nearby, because only people from their own communities come and go, and there are few passing cars. The lively places are near the school, and there are some small supermarkets."

"So the crime scene could be anywhere?" Jiang Yuan understood what he meant.

Captain Pang Jidong nodded: "Before this case, some schools had school buses, and some students walked home by themselves, or rode bicycles home. It is very normal for middle school students to walk home by themselves. If the criminal hijacked people on the road, drove a little bit, maybe he would arrive at a remote place. After committing violence, driving a little bit, driving back to his own home is possible."

This is also a conjecture. Jiang Yuan listened without saying a word.

Mu Zhiyang, who was sitting together, said at this time: "General rapists run away after finishing. Why does this person want to take the risk to do it twice?"

This is a question that everyone who sees this case will ask. Cases of secondary rape are extremely rare, and many people have never heard of them.

Captain Pang Jidong said: "Maybe it's because of stimulation. Maybe, there is a problem with psychology?" Captain Pang Jidong paused and said: "We followed the criminal psychology for a period of time before, which is the profiling of the FBI, which was done by experts from the provincial department, but we didn't catch anyone. His definition is that the criminal has impotence, and maybe he needs to be hard in a special scene. The first time is to relieve pressure, and also for stimulation."

Captain Pang Jidong paused and said: "The second time, we speculate that it is very likely to be at the criminal's place, at home, or a rented location. The criminal might also have used medicine for himself. We estimated the time based on the four victims, and ran a map, but it didn't have any effect..."

"It won't be at the criminal's home, at least not a fixed location." Jiang Yuan hadn't spoken, and said very firmly at this time.

Captain Pang Jidong had been following the Second Rape Case for a long time, and he didn't dare to say such a conclusion firmly, so he couldn't help but ask first: "Why is it not a fixed location."

"The pollen types stained on the clothes of the four victims have relatively large differences, and the proportion changes greatly. It will not be in a fixed building." Jiang Yuan had been engaged in pollen for several days. When he was idle, he also had his own analysis of the case.

Captain Pang Jidong could only nod. He was assisting Jiang Yuan this time, naturally following his train of thought, and said: "That is to say, four cases, choosing 8 locations?"

"Yes." The answer given by Jiang Yuan was completely different from the previous conjecture of the special task force.

"Arriving at the marked location A immediately." The driver reminded at this time.

Soon, the car stopped by a small road by the river.

The flow rate of the river is very slow, looking like a dead water from a distance. A sign stands by the road, named Yongtong Canal.

Jiang Yuan got out of the car and walked slowly along the small road.

Captain Pang Jidong followed closely. Several criminal police officers from another car also got out of the car and observed in all directions.

This is about a few hundred meters away from the place where the first victim was shocked. It is still very remote today, the greening is very beautiful, the big trees by the road are lush, and under the trees are green grass, and shrubs half a person high.

"It should be here." Jiang Yuan suddenly stood in front of a lawn, took a photo with his mobile phone first, then sighed, and said: "Ask the management personnel of the greening here, if there has been no major renovation in the past year or so."

"I'll ask if it's managed by the municipal government or the property nearby." Captain Pang Jidong had already found someone, and called to contact at this time.

Jiang Yuan gestured.

Mu Zhiyang immediately brought the gloves, headgear, and foot covers to him.

Jiang Yuan slowly put them on.

They were standing about 20 meters away from the river at this time. Beside them was a two-lane asphalt road, and beside them was a bicycle lane without bicycles.

The crime scene identified by Jiang Yuan was next to a sturdy plane tree, shading a large area of shade.

The lawn under the plane tree was about three or four meters wide, and the shrubs on both sides had two layers, one high and one low, only trimmed into a flat head, and also had a height of more than one meter.

Jiang Yuan could imagine that if the criminal brought the victim here, pushed her into the lawn, and then lay down, the shrubs could perfectly cover the figure.

As for shouting... as long as the victim opened her mouth to speak, she would be shocked. The criminal obviously didn't care whether the victim was awake, and whether she was dead...

According to the words of the criminal psychology expert Jiang Yuan saw in the case files, this is a kind of extreme control. The criminal just wants to do the behavior that the public dislikes and offends the most in such a place that is almost in the public eye.

Similarly, there are photos of the location where the first victim was shocked 4 times in the case files.

For an ordinary person, these four electric shocks are enough to be fatal.

It can be said that this is more fierce than ordinary punching and kicking.

If possible, this kind of person should be sent to the underworld as soon as possible.

Jiang Yuan was dressed neatly, bent down and searched nearby.

After more than a year, ordinary biological materials should not be mentioned. Now it depends on whether it is possible to find items accidentally lost by the criminal or the victim.

Captain Pang Jidong asked someone, reported back to Jiang Yuan, and helped search.

Jiang Yuan searched for about 20 square meters, stopped, shook his head and said: "It seems that nothing was left behind, mark it, let's go to the next point."

Captain Pang Jidong did as he was told, walked a few steps, suddenly stopped, looked back at this place, and was still a little uncertain: "So, we have already found the first scene of the first victim?"

"Yes."

"Just leave like this?" Captain Pang Jidong was a little reluctant. If during the special task force, he really found the first scene of the victim, wouldn't he have to dig three feet into the ground?

Jiang Yuan only said: "There are seven other places, or leave two people to take a look."

As soon as Captain Pang Jidong heard it, he left two people, let them turn around nearby, see if they could find eyewitnesses or something, and at the same time, called people again.

As an old criminal police officer, Captain Pang Jidong knew clearly that if he could find all 8 scenes, this case would naturally derive various clues. ===== CHAPTER 516 =====
