Chapter 956 List
"Regarding the case, there is new information to report to you."

When Liu Jinghui appeared in the conference room again, his hair was disheveled, his body smelled sour and stinky as if he hadn't taken a shower for a long time and smelled fresh like instant noodles, and his face was greasy. In short, he looked like an ordinary police officer from the task force.

Jiang Yuan, Huang Qiangmin, Lang Heng, Su Shanming and others sat at the other end of the conference table, waiting to listen to Liu Jinghui's speech. Others sat or stood, and some sat on chairs to watch. It was a very authentic case analysis meeting.

The task force pulled back many of the detectives that were sent out to investigate. This was the so-called action of gathering fists and preparing to hit someone. It could also be considered as sacrificing many of the previous investigation results for a bigger goal. But no matter which one it was, it represented the task force's attention and the correction of the direction of the investigation.

Many members of the task force had something to say about this - most criminal police were more familiar with and accustomed to the positive and conventional investigation model, especially the previous generation of task force members who joined later. They had limited familiarity with Jiang Yuan and Liu Jinghui, and were concerned about the 430 case. At this time, they were able to suppress their emotions and not express their opposition immediately. This was a sign of their sophistication that they had acquired through years of experience.

Liu Jinghui began to slowly describe the latest developments in the case, supplemented by his own ideas and Jiang Yuan's technical analysis.

This day or so gave Liu Jinghui time to organize his thoughts. At the case analysis meeting, he conducted case analysis for the local criminal police team, which was Liu Jinghui's specialty.

Liu Jinghui explained it in a simple and easy-to-understand way and discussed it again in detail. The expressions and attitudes of the members of the task force have completely changed.

Liu Jinghui looked at their faces and was very familiar with this expression.

At this time, seeing that no one stood up to criticize, Liu Jinghui released the ultimate move in his hand and talked in detail about Jiang Yuan's analysis of the lock core.

"Is this evidence?" Su Shanming heard such an analysis for the first time and was as surprised as Liu Jinghui before.

Liu Jinghui looked at Jiang Yuan and said with a smile: "Captain Jiang, please tell me."

Jiang Yuan then briefly talked about the identification of the traces in the lock core, and then said: "This is one of my judgments in the trace identification. I can issue a trace identification report later."

Jiang Yuan knew what the police liked most.

"This is a good judgment! This kind of trace has been covered up, and new traces have been added. I guess we will encounter it again in the future!" Su Shanming exclaimed repeatedly.

Liu Jinghui coughed twice and said, "This is the trace identification report that Captain Jiang has issued. If you have similar physical evidence, you should ask Captain Jiang to issue a report."

An old police officer nearby frowned as he listened: "Is this a special situation?"

The implication is that he is asking whether Jiang Yuan is faking it or letting the opponent win.

Jiang Yuan shook his head and said, "I will write a paper and publish it in a journal. The identification report will also be attached. The identification of the lock core this time is a little more difficult, but the rest is nothing."

This explains the authenticity of the appraisal. As for the difficulty, Jiang Yuan doesn't need to talk about it.

But most of the detectives present could understand it.

It is a basic operation for criminal police to be able to hear the other person's hidden thoughts or ideas from the content, tone, voice and body language of their speech.

Huang Qiangmin even laughed, curled his lips slightly, and thought to himself: In the future, there should be a control line for such high-end reports. It is difficult for people to judge the value of others by always letting them get something for free. This should be detrimental to other people's establishment of correct values, and it is also detrimental to the overall development of society...

Huang Qiangmin suddenly started thinking far away.

At this time, Liu Jinghui finished the explanation and started talking about the substance: "This is the list I compiled. The list is mainly composed of several parts. The first part of the list is all the people who have touched the key. This part is mainly based on the recollections of the victim's husband Mai Zuqing, plus the memories of some relatives of the victim. The main components are the victim's family, several relatives of both parents, several colleagues of Mai Zuqing, and several girlfriends of the daughter."

"The second list is an expanded list, which means we are not sure whether they have had contact, but we believe they have had contact with the keys. For example, some of my daughter's classmates may have left their keys in the classroom during physical education classes. According to the class management method at the time, basically all the classmates can be considered to have had contact, and so can some teachers. But students from other classes usually cannot. In addition, some colleagues of Mai Zuqing, some relatives who often come and go, and the beauty salon and barber shop that the deceased Sui Yingxue often visited are also included in this list."

“The third list is the surrounding ex-offenders, including juvenile offenders who have been punished.”

"The fourth list is people who have lived nearby or worked nearby and have experience or training in key making. Although the keys have been polished many times and do not look very professional, we think that this may be a problem with the source of the keys, and on the other hand, key making may also require relatively professional equipment?"

Liu Jinghui listed several considerations in one breath, and the list he listed was also a long and dense list.

The investigation 10 years ago had laid a good foundation, and basically recorded all the people near the victim's residence. Despite this, the number of people listed by Liu Jinghui was still beyond imagination - of course, beyond the imagination of ordinary people.

The detectives present were very calm. This was the third 430 case, and if they didn't investigate tens of thousands of people this time, the leaders would feel that they had not done their best. Although Liu Jinghui's list was quite long, in everyone's opinion, it was completely within a reasonable range.

"How do we investigate?" Lang Heng asked a key question while waiting for Liu Jinghui to drink some water because he was so thirsty from talking.

You can't interrogate all of these people on a list. Even if you do, it can't be a protracted one. There have to be some key points for the detectives to grasp.

Of course, if you really have no ideas and want to exchange time for space, then you can send people to inquire according to the list, also known as visiting, which was a magic weapon for investigating cases in the early years.

"In fact, we can make our list smaller." Liu Jinghui paused, and said, "I think the geographical factor is a very important factor. Think about it, if the murderer tried to open the lock many times and had the leisure to go back and file the key and open the lock again, he must have lived closer to the victim's house to facilitate this process."

"This guy is a pervert," a criminal police officer shouted, "his purpose may be to break into the house and rape or molest, but he is an impotent or premature ejaculation man, and he got it in his pants."

Liu Jinghui nodded: "It is indeed possible, but think about it, can't the pervert find a suitable target near his home? Is he so picky?"

"The victim was his white moonlight?"

"Then the relationship between the murderer and the victim will be relatively close, and there is a high possibility that they are strong contacts." Liu Jinghui gently refuted, and then said: "Generally speaking, perverts commit crimes in places that are convenient, familiar and safe for them. This is more in line with common sense. I recommend the method of visiting and investigating with the victim's home as the center and gradually expanding!"
