Seeing the old man's performance, Liu Pengcheng stopped talking.

If it is really what he thinks, no matter what he says, the old man will not admit it. You have nothing to do. The old man is already seventy years old. Being able to open a store in this place should be a task at the level of a grandmaster in the industry.

, what can you do to him? Moreover, Lao Du didn't even bring Xiaoxia with him when he met him, and he didn't even have any circumstantial evidence, so Liu Pengcheng could only let him speak out on his own.

Liu Pengcheng paid the money, and the old man issued an invoice and said he would pick it up in three days.

Liu Pengcheng took Xiao Yang and Xiao Liu out of the jewelry store without stopping at all. He went directly to the parking lot outside the street and drove away.

In the car, Xiao Liu asked: "It should be him."

Liu Pengcheng said: "It should be him, and it can only be him. The next step is to bet on how deep the relationship between him and Lao Du is. After all, it is a crime!"

Xiao Liu said: "If Director Liu puts his hope on this, it's a waste. This old man is a cautious person, and he didn't even go to see Lao Du for the last time."

Liu Pengcheng said: "It's not that I want to pin my hope on this, but I can only pin my hope on this. Think about what he did for Lao Du, can he easily say it himself? He won't say it

, I am so old, what can you do? At this age, you can try sending one to the detention center and see if they dare to accept it!"

Xiao Liu sighed: "Oh, that's what you said. There is no other way."

To be honest, Xiao Yang basically didn't understand this conversation because as a police officer, he was still too young.

Returning to the Public Security Bureau, Liu Pengcheng received news that the criminal police detachment had found something and asked him to take a look. Liu Pengcheng took it and took a look and sighed in his heart. The detachment is so lacking in clues now that they actually found out all this.

Found out.

What was found?

They are the bank accounts of the No. 3 Canning Factory and Lao Du's private bank accounts.

From the accounts, we can roughly see how much money Lao Du withdraws from his profits every year and how much money he deposits into the bank.

Moreover, the Criminal Police Detachment has roughly calculated the total difference to be 1.74 million.

In other words, a total of more than one million yuan in cash was withdrawn from the factory's account, but was not deposited into the bank.

Moreover, this is not a record of one bank, but a record of all banks.

This number is similar to what Liu Pengcheng roughly calculated. But in Liu Pengcheng's heart, this is still meaningless, it is a wasted effort, and again, there is no guarantee that the money has been spent.

To give a very extreme example, I have this money, but I lose it all in a gambling game with Lao Du. Is it okay?

So Liu Pengcheng still used his old method, starting with people. As long as he found the person who helped Lao Du hide the money, it would not be a matter of proving the existence of the money. He should have even found the murderer.

But Liu Pengcheng was not in a hurry, but quietly waited for three days.

The information from the ministry was finally sent.

Liu Pengcheng also received a call from Brother Mu. It was actually very laborious to prepare the information on the concatenation and merger cases for them this time. This was not the time of information-based office work. It was not easy to find a few case files among the vast amount of information in the department.

Moreover, he said that he was looking for information on the "disinfection murder case", but it was not that easy to find!

Let me tell you one thing. Two groups were fighting and a knife was used. Someone used a Japanese sword to cut open the intestines of a member of the other group. Does this count?

Of course not!

Therefore, the ministry sent them information on five cases in total. From 1982 to 1996, the time span was as long as 14 years.

Not to mention the criminal police detachment, everyone in the crime center was busy reading these materials. Liu Pengcheng simply skipped the beginning and the end and read the first and last cases first.

The first case occurred in southern Yunnan Province in 1982. The deceased was a doctor and the deputy director of the local hospital. He was still killed at home at night, but the one difference was that he was disemboweled and disemboweled.

The part of his stomach was not on his stomach, but on his chest. His chest was opened. What puzzled Liu Pengcheng was that this was obviously not a difficult case, and the suspect was clearly pointed. He was obviously a

The doctor did it. Opening the chest and slicing the belly are two completely different things! Opening the chest is much more difficult!

However, judging from the case file, the investigation of this case was very perfunctory, and the records were also messy. The case was dragged into an old case.

The attitude of the department is also very strange. There are too many differences between this case and other cases. Why is it being sent over?

After looking at the first case, Liu Pengcheng started looking at the last case.

The last case occurred in 1996 in Songjiang City, Songjiang Province in Northeast China. The deceased was a beggar, and the incident took place at a construction site where construction had stopped in the winter. The deceased, like Lao Du, was covered in cuts, and his throat was finally sealed with a knife.

It was also a dissection of the intestines, which was very similar to the current case.

Even though he was a beggar, the Songjiang City Police also made great efforts to investigate the case. Unfortunately, due to the identity of the victim and the unlucky place, the body was not discovered until several days later by the workers at the construction site.

, and after the crime was committed and before the body was discovered, a heavy snowfall perfectly covered all traces of the suspect. And it was impossible to find out the social relations of a beggar.

Liu Pengcheng looked at the brief information of these cases. If the six cases were arranged according to time, they were 1982, 1987, 1990, 1992, 1996, and then the 1997 case.

Looking at the locations where these cases occurred, from northwest to northeast, southwest, and south of the Yangtze River, they are so far apart! Moreover, no two cases are in the same province!

Liu Pengcheng frowned. This is too strange!

At this time, Professor Xiao walked up to Liu Pengcheng: "Xiao Liu, have you discovered anything?"

Liu Pengcheng said: "The first time."

Liu Pengcheng casually took out a piece of white paper, drew a line, and divided it into about fifteen parts simply and crudely with a pen. Then he pointed out the resulting years of 1982, 1987, 1990, 1992, 1996, and 1997. If you look at the numbers alone,

It's not so intuitive yet, so you can see it by drawing a separate coordinate axis like Liu Pengcheng.

This chapter is not over, please click the next page to continue reading! The first and second incidents were separated by five years, then three years, then two years, then four years, then one year. This is very strange. Before and after

It's all normal and consistent with the characteristics of perverted murders, that is, the time intervals are getting closer and closer, but no more crimes were committed from 1992 to 1996. This is four years! And after the suspect committed another crime in 1996,

In 1997, it was only one year apart.

Professor Xiao looked at the timeline drawn by Liu Pengcheng and said, If we assume that these cases can be combined, then it is abnormal that the suspect did not commit any crime in the four years from 1992 to 1996. The reasons for this situation are:

How many kinds?

Professor Xiao continued: "Let me first tell you something that is unlikely, that is, he received psychological counseling treatment during this period!"

This is definitely a possibility. If you accept it, you will no longer commit crimes, but it is unlikely and true. Because from 1992 to 1996, the number of psychological clinics in China that were open to the outside world could be counted on two hands.

Professor Luo, who was watching from the side, also said: "Then let me say one thing. The suspect was injured or sick during this period."

This is also a possibility, and the possibility is not small.

Then there was Mr. Qian. He said with a smile: "He may be serving his sentence, but he has not confessed to the remaining crimes."

This possibility is also possible, and it is very high.

Liu Pengcheng said: "It may also be that he has undergone major changes in his life, such as starting a family, getting a good job, etc."

This is really possible. The suspect felt the warmth of the family and the desire to commit crimes in his heart was not so strong. But when the novelty wore off and he began to get tired of the life of rice, oil, salt, sauce, vinegar and tea, he started committing crimes again!

Director Dai also said: "There is another possibility, which I personally think is more likely, that is, he committed a crime, but did not commit it!"

While everyone was still discussing the possibilities, Liu Pengcheng's cell phone rang. He picked up the phone and saw that it was actually a call from Director Zhao's office. He hurriedly answered: "Hello, leader!"
