Serious Crime Unit 1

Chapter 752 Traps (13)
It turns out that this is a small alley, about 3 meters wide, with abandoned houses on both sides. No one lives in it. The original residents may have moved away a long time ago. At this time, the midday sun shines directly on the road, giving off a dazzling light. A stray dog ​​stood nearby and looked at Wujiang.Wu Jiang squatted beside the manhole cover and took pictures of the manhole cover with his mobile phone.

"Old Wu, what's going on?" Jiang Yiming stepped forward and patted Wu Jiang on the shoulder.

"Look, this manhole cover has been moved by someone, and the edges of the cover are covered with loose dust." Wu Jiang motioned for him to squat down and take a look.

This is a circular manhole cover with a diameter of 100 centimeters, made of cast iron. It has obviously been displaced because it does not completely line up with the original gap.Generally speaking, it is impossible for anyone to move the manhole cover in such a remote place. It is highly doubtful that the suspect may have opened the manhole cover and escaped from the sewer.

However, because it rained heavily that night, all traces were washed away. There were no footprints on or beside the manhole cover. There were two small holes on the manhole cover, which were convenient for opening the manhole cover. Just insert one Use a screwdriver to open the manhole cover.One of the small holes has traces of being rubbed by iron tools.

This is a manhole cover that weighs 52 kilograms. It is difficult for a person to open it without borrowing tools. In addition, it has been guarding the manhole for many years and has "taken root". Therefore, it not only weighs 52 kilograms, but also needs to be opened. To open it, you have to spend at least 60 to 70 kilograms of effort and borrow tools.

Jiang Yiming and Wu Jiang put on gloves, lifted up the manhole cover together, and carried it to the side of the road. Below was a manhole nearly 3 meters deep. Jiang Yiming took out a miniature bright flashlight to shine on the bottom of the well, and found that there were several A less obvious footprint.

Next to the manhole, there is a U-shaped ladder for people to go up and down. This ladder is made of steel bars and is fixed on the wall of the well. There are steps every 80 centimeters. Jiang Yiming wanted to go down the ladder to the bottom of the well, but Wu Jiang dissuaded him. .Wu Jiang was afraid that he would be poisoned, so he asked him not to go down yet. He called Luo Jin and asked Luo Jin to send two sets of chemical protective suits.

After a while, Luo Jin brought the chemical protective clothing. After Luo Jin put on the chemical protective clothing for Wu Jiang and Jiang Yiming, he stood guard above the manhole.

There was wet mud at the bottom of the manhole, and there were three shoe prints on it, but because they had been washed away by the rain, no shoe prints were left. The shoe prints were also very shallow, less than 1 centimeter deepest.The numbers on the three shoe prints are all size 43 sneakers, which matches the suspect's height.

Wu Jiang took photos and fixed the shoe prints, and then extracted the shoe prints with soft plaster. After the extraction, he handed it to Luo Jin, and then he and Jiang Yiming searched along the 1.5-meter-diameter sewer, hoping to find more traces. .

The sewer is made of cement, and the sewer leads to the sewage treatment plant. If the suspect escaped from the sewer, he could not have walked along the sewer until he reached the sewage treatment plant before getting out of the ground, because the sewage treatment plant At a distance of 15 kilometers, almost no one can bend down and walk 15 kilometers, because the closer to the sewage treatment plant, the larger the sewage will be.

The suspect must have walked several kilometers along the sewer before drilling out of a manhole. However, because sewage flows through the sewer day and night, all traces have been washed away.Even if they kept searching, they couldn't find anything. All this was carefully calculated by the suspect.

Jiang Yiming and Wu Jiang had no choice but to return to the ground and take off their heavy chemical protective suits. Although it was winter, their underwear was already soaked with sweat.

"Old Wu, what should we do now?" Jiang Yiming asked.

"The footprints in the manhole are about the same height as the suspect, which can prove that the suspect escaped from the sewer. Unfortunately, we didn't think of it at the time. Otherwise, if we come here in time to look for traces, we will definitely gain something. What we have to do now is to continue to search. The suspicious manhole cover may reveal which manhole the suspect climbed out of, and in that case, dense surveillance cameras may capture the suspect's appearance."

"If the suspect climbs out of a manhole three kilometers away, our work will increase exponentially, and the scope will expand to dozens of square kilometers. If the suspect is very strong-willed, he will drill out seven or eight kilometers away. When it's on the ground, I don't know what year and month we want to find out?" Jiang Yiming thought this method was too stupid.

"First search within two or three square kilometers. If no clues are found, we will discuss it again." Wu Jiang was more patient and calm than Jiang Yiming.After Jiang Yiming heard this, he nodded to Wu Jiang, so they both went to look for the suspicious manhole cover.However, they searched for a day and found nothing.

When Jiang Yiming returned to the team's cafeteria for dinner, he suddenly remembered the tracking dog Xiaohu. Xiaohu was thin and ferocious in appearance. He had an indomitable and magical olfactory tracking ability. He could track odors even if they were more than half a month old, and he had set a record of continuing to track 200 times. It is said to have 3.5 million olfactory cells, making it one of the best tracking dogs.If Xiaohu comes to help, the suspect may be traced.

Jiang Yiming took out his mobile phone, called trainer Xiao Bing, explained the situation to him, and asked him if he could help track the suspect.When Xiao Bing heard that it was a sewer, he immediately said that Xiaohu would not be able to track it, because the sewer is the most smelly and complex environment, and there is a lot of water, just like it is impossible to track the target on the river.He had been invited to take Xiaohu to the sewers to track the target before, but without success.

When Jiang Yiming heard this, he was a little disappointed, but this made him believe that it was done by an expert or even a colleague, because he knew all the anti-investigation methods, including tracking dogs, and Gu Yijun had never been in the police or the military. At least he didn't shoot Yang Changan with his own hands.Jiang Yiming believed that investigating this clue would consume a lot of energy and time, and what he needed most was time. There was no problem with energy and police force, so he had to look for new clues.After thinking about it, he felt that the murderous gun was also a clue. If the source of the murderous gun could be found, then the murderer could be found.

Jiang Yiming asked Lu Yingying to help find recent gun trafficking cases in the city in the collaborative case handling system, record their case details, of course the gun trafficking cases that have been solved, and then write down the names of the people involved and the investigators so that they can go to Look for clues.

Although Lu Yingying did not have the right to participate in the case discussion meeting, with Jiang Yiming's authorization, she could enter the collaborative case handling system for inquiries.After receiving Jiang Yiming's instructions, she entered the key and entered the collaborative case handling system for inquiry. Finally, she listed three gun trafficking cases from the beginning of 2017 to the present, and then added the names of the imprisoned gun dealers and the names of the investigators. Print out the list and closing time and give it to Jiang Yiming.

Because the specific case handling situation cannot be queried in the collaborative case handling system, you must go to the case handling personnel.Among them, a large-scale gun trafficking case on May 2017, 5 was detected by the Jiangnan District Security Team. There were 2 guns, 35 bullets, and 210 people involved in the case.

The investigator of this case was Nan Yifan, the security captain of Jiangnan Branch. Jiang Yiming and Zhou Ting both knew him, so they came to Jiangnan Branch to find Nan Yifan.

Nan Yifan is almost 50 years old, but he is in good spirits. He is tall and strong and looks several years younger than his actual age. He could have retreated to the second line and become a consultant or something like that, but he is determined not to. Leave the front line.Such people are very rare, because the front line is not only hard and tiring, but also very risky.Therefore, Jiang Yiming has great respect for police officers who are willing to stick to their posts for the people.

Nan Yifan happened to be reading information in the office when he saw Jiang Yiming and Zhou Ting visiting. He was so enthusiastic that after hugging them, he even shook hands with them.

After the two parties sat down, Jiang Yiming explained the situation to him. Nan Yifan said: "This case was investigated by me personally. The principal criminal Chen Xuefeng was sentenced to 35 years in prison for selling a total of 9 imitation Type [-] pistols and Type [-] pistols. This It was still the result of his voluntary confession, otherwise he would have been sentenced to more years."

"Where is Chen Xuefeng being detained now?"

"He is being held at Urata City No. [-] Prison."

"We want to find him. Do you think he will atone for his crimes?"

"Definitely. If his sentence can be reduced, he would be happy to ask for it. I heard that he regretted it very much in prison. In order to get rich overnight, he wanted to waste his most splendid youth in it. And he knows the law very well, but he is greedy, so he Take this path.”

"It would be easier if he was like that."

"Don't you think he has confessed all his crimes?"

"No, we think he may remember some clues that he has forgotten." Jiang Yiming replied tactfully, he did not want to refute Nan Yifan's face.Under normal circumstances, suspects will not confess to all crimes, because the more crimes, the heavier the sentence.

Jiang Yiming and Zhou Ting came to Putian No. [-] Prison. They were regular visitors here, so they were familiar with the warden Wei Dazhuang. After meeting, Jiang Yiming directly asked him to see Chen Xuefeng, and Wei Dazhuang invited them to sit down. After getting off, he asked the prison guards to take Chen Xuefeng to the pre-trial room.

Jiang Yiming quickly went to correct him: take Chen Xuefeng to the lounge.Wei Dazhuang repeated what Jiang Yiming said to the prison guard, and the prison guard nodded and left.Jiang Yiming was afraid that taking Chen Xuefeng to the pre-trial room would make him rebellious, so it was better to meet him in a relaxed atmosphere. Besides, they were not here for interrogation. Jiang Yiming grasped this very well.
