"It's not unusual for people from the late 1990s to now make money, become successful, and become famous. However, the table you asked Wang Chuanxing to compile is indeed a bit interesting."

Liu Jinghui was quite interested in the new plan proposed by Jiang Yuan.

He and Jiang Yuan are both people who have investigated many backlogged cases. Therefore, everyone understands that the focus of investigating backlogged cases is not to repeat the path taken by the predecessors. Even if your skills are very good and your reasoning ability is very strong, after passing After so many years, if we walk the same path as our predecessors again, will we be able to do better?

It is normal to make stuffed rice.

Especially in criminal cases, many cases do not reach a definite conclusion until the end. If the found murderer does not admit it, how can he prove that the case was not an unjust, false or wrongful case?

Time will destroy the evidence, not only the evidence that proves the murderer is suspected, but also the evidence that can prove the innocence of the innocent person.

Therefore, many times, investigating backlogged cases requires finding angles that have not been done before.

New angles, new routes, and possibly new evidence, this is a better investigation plan. Of course, it may not be possible to solve the case, but this method is already very good for a backlog of murder cases.

Jiang Yuan's "prosperity" plan is a new angle. The core of it is actually very simple, that is, whoever benefits is the mastermind.

This is also the most commonly used reasoning strategy in administration. There are hundreds of papers and monographs available for core and specific analysis, but it is not that easy to apply it in practice.

Liu Jinghui likes Jiang Yuan's "compromise" on the reasoning flow.

Liu Jinghui carefully read the list provided by Wang Chuanxing, clicked his tongue again, and said: "Don't tell me, the people in Beijing in the late 1990s who have survived to this day are not in bad conditions. The worst thing is that they have not bought a house. , as long as you buy a house, you will have a net worth of at least several million, but some people are better off than others.”

"After all, it has been more than 20 years, and some people must have sunk."

"Well, this is also a bug in your plan. If some people rise and then sink again, how will it be calculated?"

Jiang Yuan thought about it and said in a probing tone: "You don't have to see what it is like now. A few years after the incident, especially those who started their business in five or six years, they should pay more attention."

Liu Jinghui nodded: "That's an idea. Ordinary criminals can't wait for you to fulfill your promise in ten years. Three to five years is long enough. However, let me update your idea."

"You say."

"Anyone who has gained momentum will be counted. As long as the income has increased dramatically, or has become rich suddenly, no matter what the reason is, whether it is inherited, gained from stock trading, or picked up, we don't care about anything. Anyway, Jianmenyuan is such a large area, and anyone who has ever been rich is listed as a suspect. "

"Okay." Jiang Yuan agreed.

"Those who get promoted also count."

"Yes." This point was quite sensitive, so Jiang Yuan didn't say much.

Liu Jinghui threw the list back to Wang Chuanxing and asked him to continue revising it.

Wang Chuanxing had already carried out a thorough and refined operation at this time. He pulled out the list of all the residents in Jianmen Courtyard and handed them over to different people in different categories. He then listed everyone's economic status, career development, and life trajectory in the past twenty or thirty years. List them all.

A total of several hundred residents in four buildings were assigned to more than 20 police officers, and they were screened in a short time.

There are many points that can be screened here. In addition to bank deposits, securities accounts, real estate and car licenses, each person's monthly phone bill amount, transportation expenses, whether they have flown business class or first class, whether they have traveled abroad, and even The experience of studying abroad, children’s education expenses and medical expenses for the elderly, etc., can all be used as background.

From the police's point of view, ordinary people are actually the same. They only have so much money to spend, and they basically spend it on the tip of the knife, and occasionally spend money on some special places.

But if he is a hidden rich person, he will often spend extra money in some inexplicable places. In other words, he actually does not care too much about the expense issue, and even intentionally spends more money in some unobtrusive places. money. And as long as similar entries appear, the police will naturally pay more attention.

Soon, a list of more than 30 people was placed on the desktops of Jiang Yuan and Liu Jinghui again.

Liu Jinghui and Jiang Yuan read it separately, also with files and computer background information.

After a while, Liu Jinghui gave a cross to the 10 people in the first row and said: "There are some business people who are greedy for money, but they don't feel like the people we are looking for."

"The person we are looking for must be able to fly claws." Jiang Yuan frowned slightly and said, "I don't know what kind of person can still learn this thing in the 1990s. By the way, this is still a young man, Under 30 years old.”

"Yes, but you can't directly screen the age. The money may not be spent by yourself. Furthermore, it may not be the resident, it may be the resident's family or someone else." After Liu Jinghui started to think, he thought more.

Jiang Yuan thought for a while and said: "I think this murder case is less and less like a death case caused by burglary. From this point of view, if it was not caused by burglary, then the murderer obviously has something more. Big reasons, more benefits, will do this.”

Liu Jinghui said, "Yes," and said, "I understand what you mean. You want to directly build a list of people who have profited from killing Zhang Xiaoming. This direction is indeed possible. Consider this direction first. If it doesn't work, then talk about other investigation directions..."

Liu Jinghui said, and began to summarize, saying, "First, the murderer asked someone to open the lock for 500 yuan. This shows that he has money. Secondly, he took thousands of yuan of money and things from Zhang Xiaoming, and later shared them with Wang Futing, which is very generous. From these two points of view, the murderer's financial situation should be relatively affluent."

Liu Jinghui said, while looking for people in the list.

There were more than 30 people on the list in total, and with factors such as age, Liu Jinghui soon pulled out two names.

"Investigate them first." Liu Jinghui didn't do any re-examination. Now that the resources are abundant, I'm afraid there are no clues to check.

However, the young people of more than 20 years ago are now very old. Fortunately, there are few people who move to Beijing. These two people still live in the local area, so it is not difficult to investigate.

Several police cars drove out lightly. Calculating the time, it is estimated that it will take several hours to get the results.

Liu Jinghui patted the file in front of him: "Since we are here, how about checking Zhang Xiaoming's work unit in the same way?"

He thought this method was very good. There were many restrictions. If it was really checked, there would not be many people on the actual list, and the burden of investigation would not be heavy.

Jiang Yuan did not object, so the members of the entire backlog special team were mobilized again to find the list of the factory, and then divide it into individuals to investigate one by one.

Compared with the previous process, the current process is a little faster.

Moreover, compared with the colleagues who are mainly government officials living in Jianmenyuan, the conditions of simple factory workers are often not good. There are very few who can reach the level of "rapid rise" and "successful and famous". The list of more than 2,000 people was finally pulled out of dozens of people, which made it more convenient to investigate.
