Chapter 080 There is a new case in the copper mine, and everyone is saying

The meeting in the evening was held as scheduled, and the two arrest groups reported their own reports, in fact, the other groups had already known the results, and we just made a specific explanation of the reasons and basis for the exclusion.

Both satellites fell in the dawn of dawn, and the conference room was dull.

Judging from the reports of other groups, there are quite a few cases of the same type, but there is no basis for joint investigation. There are also a lot of key suspects,

The Zhang brigade was responsible for the prevention, and the work was carried out in all villages, and the village party secretaries and village chiefs attended the meetings of the two institutes.

Other work remains unchanged, the meeting finalized several measures:

1. Further deepen and expand the work on collusion and merger cases;

2. Collect blood from all suspects;

3. I took Xiao Ke and Xiao Cao to focus on a series of rape cases, and Captain Zheng returned to the team to deal with daily affairs.

The investigation of the case seems to have returned to the starting point, the field investigators are investigating and investigating the key objects every day, and the very suspicious people are collecting blood, and several members of our technical team are cooperating with the investigation of key suspicious personnel according to the investigation of each group.

The days went by day after day, and although I was anxious in my heart, I was suffering from no good way.

On the morning of May 24, another report was received that Zheng Xiumei (female, 15 years old) of Zhengjiawan in Dating Village, Tongkuang Village, had been raped. Scratches on the chest.

It's only been 8 days! The perpetrator really started to commit crazy crimes again!

NND, so many people in our criminal investigation brigade are busy going in and out every day, passing through the village and transferring households, you haven't seen it?! Do you really think we can't solve the case?

It's a challenge! It's a naked challenge!

As soon as Director Zhang heard that another case had been issued, he hurriedly led everyone to the scene; After receiving the notice, Captain Zheng also rushed over, and we jointly conducted an investigation of the scene.

The evening meeting was held as scheduled.

When it was the technical team's turn to report on the on-site investigation, Captain Zheng said:

"The situation is just as Captain Li analyzed, at about 2 o'clock in the morning today, this series of rape cases happened again, according to the on-site visit, combined with the on-site investigation. On behalf of the technical team, I would like to give a briefing on the on-site investigation.

The site is located at Zheng Xiumei's house in Zhengjiawan, Poting Village, Tongkuang Town. The house is a brick and concrete structure with two bungalows, located in the middle of Zhengjiawan, sitting north and facing south, and the east and west sides are Zheng Lijun's family and Zheng Chuan's family respectively. The north and south sides are separated by 12 meters of open space and Zheng Zhiqiang's house and Zheng Lijun's house respectively.

The perpetrator entered the house by climbing. That is, from the west side, Zheng Chuan's family and Zheng Xiumei's house adjacent to the small alleyway. I climbed into the room to go up to the platform on the first floor, and then went down from the platform on the first floor along the open door to the first floor and came to the back of Zheng Xiumei's house. At this time, the back door may have been opened. Then, using the same method as before, that is, using the rope that came with him, he reversed the lock of Zheng Xiumei's parents' room on the east side, and then pushed open the door of the room where Zheng Xiumei slept on the west side, or got off the light bulb in the room, and then used a special tool to knock Zheng Xiumei unconscious, and then raped him.

We found white fibers on the steel bars of the south window of Zheng Xiumei's room on the west side, and traces of gloves on the windowsill, so we can be sure that the perpetrator climbed on the south window and peeked into the room before committing the crime, which means that the perpetrator entered the house after confirming that only one person in his room was sleeping.

After committing the crime, the perpetrator took the light bulb, removed the rope, and fled the scene through the back door.

In terms of trace evidence, we extracted traces of the perpetrator's tools, gloves, fibers, and traces of the perpetrator's socks.

"Got the footprints of the perpetrator's socks?" Director Zhang asked.

Captain Zheng nodded and said:

"This sock footprint was left on the tile on the west side of the landing on the first floor. Judging from the interview, Zheng Xiumei's house was built in October last year, and her parents decided to install white tiles on the outside in consideration of waterproofing and aesthetics. Therefore, it was very fortunate that we found glove prints and sock footprints where the perpetrator climbed. Based on the freshness of these two traces and the interviews, it can be determined that these are the traces left by the perpetrators.

Let me tell you about the sock footprint.

This is a fragmented sock footprint, reflecting the forefoot part, the five toes, the outer contour of the forefoot are well reflected, but because it is a sock footprint, it can only reflect the line pattern of the sock bottom, and there is no sole pattern reaction.

The size of the tile is 10*25CM, such a small range of a tile has been able to better reflect the socks footprint, its size is as follows: 8CM long, 7.5CM wide, left for the forefoot part of the left foot.

After my research with Captain Li, it was determined that the fingerprint of the sock-wearing foot can be identified, although it is a sock footprint, but it can reflect the contour of the sole of the foot, and the contour of the sole of the foot is different for each person, so it has the same identification conditions.

The injuries of the victim, Zheng Xiumei, are as follows:

There are two parallel scratches on the right side of the chest, with a length of 5.5CM, a single scar with a width of 2CM and a depth of 0.2CM, and a distance of 5CM between the two scars. This trace situation is basically similar to the previous one, and it is formed by the same tool.

In addition, we extracted sperm spots, which were quickly verified by forensic doctors and found to be type B, which is exactly the same as the blood type extracted in previous cases.

To sum up, this case can be investigated in conjunction with previous cases, and in this case, we have finally extracted traces that can identify the perpetrator, which is a breakthrough.

That's basically what happened to the on-site investigation. ”

Director Zhang said:

"In this on-site investigation, your technical team was finally able to extract the footprints of the perpetrator's socks that can be identified, and the conditions for the same identification are met. It's very good, it's a major step forward. I hope you will be more serious and meticulous in surveying the site. More useful traces and physical evidence are extracted to provide a greater support point for the breakthrough of the case. Captain Lee, do you have anything else to add? ”

I shook my head.

Director Zhang went on to say:

"Captain Li, judging from the situation of the perpetrator climbing, does the perpetrator have any experience as a soldier?"

I nodded and said:

"Regarding Director Zhang's experience of analyzing whether the perpetrator is likely to become a soldier from climbing, we have repeatedly conducted experiments on the spot, and we cannot come to this conclusion, we can only say that the perpetrator is relatively strong, has great strength in both hands, and is good at climbing. Several of us on the technical team have tried it. You can basically climb up. ”

Director Zhang nodded. Said:

"Do other comrades have anything to add?"

Everyone shook their heads and remained silent.

Director Zhang continued:

"Okay, then I'll summarize. According to the information reported by everyone, the time of the crime occurred between 11 o'clock and 5 o'clock in the morning last night. The perpetrator climbed into the house. Committing crimes with special tools for committing crimes. There were sock prints of the perpetrator left at the scene, and the perpetrator's blood type was B......

Next, let's talk about the next work plan and measures. ”

Tan Team Leader Says:

"This string of cases. I have also participated in several special classes. At present, the investigative measures we have taken are the same as those of the previous ones, that is, to investigate and find out the key suspects, and to collude with cases. I don't deny the usefulness of these investigative measures, but I always feel that we have to find other ways to solve the case, otherwise we are very likely to repeat the mistakes of the past.

So what's the best way to do it? I suggest a catch-and-hold approach. The reason for this is as follows: The Zhang Brigade has already assigned the prevention and control work to all villages, and this case is still continuing to occur; it seems that our extensive method has not touched the perpetrators, and relying on several village party secretaries and village cadres to help us discover the situation at the same time will not achieve our investigative purpose, and we must catch and wait by ourselves, and rely on the masses to carry out this work in an unorganized manner, and the role played is not very great.

Secondly, I agree with the analysis of 200,000 yuan, and the perpetrator will continue to commit crimes, which is the premise of capturing and waiting. I analyze the psychology of the perpetrator now, it is not only a kind of joy after committing the crime, but also a contempt for our work, he does not take us seriously at all, he is in a state of madness, this state of madness is precisely the time to expose his weaknesses, we must seize this favorable opportunity to capture him. As the saying goes, the arrogant army will be defeated, and I suggest that the method of catching and waiting should be taken at the right time.

Third, on the specific deployment of capture and waiting. I know that this work involves a lot of police forces, and we have a limited number of police officers, so this work of capturing and waiting is responsible for and organized by our group, and our team does not involve other police forces, of course, I hope that 200,000 can join in.

This is my initial idea, which is not mature enough, and I would like to ask the leaders and comrades to correct it. ”

张大 says:

"I also agree with the view and practice of the team leader, we must catch and wait. Of course, it is impossible for a few of us to accomplish this work, and we must mobilize the masses, follow the principle of combining the special investigation line with the masses, give full play to the strength of all villages and groups to serve our investigation and crack cases, and fight a war in which the masses of the people round up and hunt down the demons. ”

Teach Liu says:

"If the masses are mobilized to capture and wait, and the scope is too wide, it will cause panic and uneasiness among the masses, cause social instability, and then we are afraid that it will increase the pressure on us to investigate and solve the case, and if the news is leaked, the perpetrator will stop continuing to commit crimes, and we will lose a grip because of this. Therefore, I would recommend that you carefully consider the option of waiting for capture. ”

Subsequently, there was a heated discussion on the waiting capture plan, some for and some in favor, and the atmosphere in the conference room was very lively for a while.

"Is there any other way to do it than this one?" Director Zhang asked.

"For those who have a history of rape and molestation, I suggest that a special team should be investigated, and this kind of person should be the focus of our work." Team Leader Ke said.

"I think the investigation and interview work should be more in-depth, I don't believe that after so many years, so many cases, so many victims and witnesses, no one has been able to identify the perpetrator, I think, there is no negligence or omission in our investigation and interview." Team Leader Huang said.

……

Others offered suggestions and suggestions, each with their own plans, and Director Zhang recorded while listening, looking up at this and that from time to time.
