Chapter 542: Advance

"The real estate information of 20 years ago can only be checked in the archives of various cities and counties."

Liu Jinghui also asked people, and then shared information at the meeting.

The police officer sent by the Huo City special task force said: "This shouldn't be difficult. The victim was a cash transaction. We will find out all the real estate transactions in cash within three years before the incident. The volume of housing transactions back then shouldn't be large..."

Xu Tai-ning pondered and said: "It can't be guaranteed that the house was bought in Huo City."

When the police officer in Huo City heard this, this logic was really no problem. If the victim bought a house for herself, it is indeed possible to buy it in Huo City, but if it is not under her own name, is it bought for a wild man?

If the wild man is the murderer, he has made cases along the Jingyang Line in three places, proving that he is very familiar with the railway lines in three places, at least three places. Then, wouldn't the scope of buying a house be expanded to these three places?

"That is Huo City, Qingbai City, Changyang City?" Liu Jinghui read these three places, and his scalp felt numb.

Huo City and Qingbai City are still fine. Two prefecture-level cities, placed 20 years ago, how much real estate transaction volume can there be? But Changyang City is different as a provincial capital. Even 20 years ago, it must be at least ten thousand sets per year.

Xu Tai-ning said: "There is also the Railway Bureau."

"Eh?"

"The Railway Bureau 20 years ago should still have welfare housing. It is not necessarily distributed in which city. It is still necessary to consider that the murderer may have a railway background and may use this identity to buy a house."

Liu Jinghui hissed, Xu Tai-ning's logic is through, but the funds are also "through" and thrown into the water.

"Fine, this can be considered part of the investigation." Liu Jinghui felt that spending so much money was a bit too much. He is also a person who often hosts investigations, and he is also a person who likes logic and is good at logical analysis, but he would definitely not spend money like this.

In this year, there are not many police bureaus willing to invite logic kings to help. If you spend money like this, the party A will definitely explode.

Of course, Liu Jinghui cannot stop Xu Tai-ning from spending money, and he also knows that in this year, some party A are born M. When they encounter Xu Tai-ning, they may feel that spending a hundred yuan is not much.

Of course, Xu Tai-ning's judgment is correct, and the houses of the Railway Bureau, the welfare housing distributed a few years before the incident, should all be taken into consideration.

In fact, it is accurate to include all the houses in the province. After all, you don't know where Liu Limin's boyfriend is from. What if he bought a house in his hometown—Liu Jinghui just thought so, and his thoughts drifted away in an instant.

The next task is still heavy.

Xu Tai-ning is also busy turning around.

This investigation is different from the usual investigation. The scale of the investigation he organized this time is mainly reflected in the large number of personnel arrangements, task allocation, and various logistics support, work promotion, etc.

And this time, the scale of the investigation site he organized is not large. Although tracking several clues at the same time, the number of people invested in each clue is only about a hundred. In other words, so far, Xu Tai-ning has only organized and invested three or four hundred people.

This number is of course much larger than the general investigation of Shannan Province, but it is not an unusual number in the "investigation circle."

The ordinary branch bureau in the capital faces a current homicide case, organizing a 3,000-person scale investigation is like playing.

However, the investigation Xu Tai-ning is doing this time has a characteristic of being gone once sent.

Simply put, the police officers sent out cannot come back for a while.

Whether it is checking real estate transactions now, or tracking the individual households in the market before, or the owners of the footprints that appeared near the scene, the people sent by Xu Tai-ning to investigate, as long as they go out, they cannot come back in a short time.

These police officers, on business trips all over the country, once they arrive at a place, they have to investigate the local situation as much as possible, and the more so, the higher the difficulty, the longer the investigation time.

This is very different from Xu Tai-ning's previous investigations.

It belongs to the high-turnover mode of large capacity, which has been forced to change to a low-capacity, low-turnover mode.

Xu Tai-ning is also scratching his head for this.

To be honest, getting 3,000 people to dig for bodies on the highway is not a too high-requirement job. There is always a way to mobilize 3,000 people.

Now it's good, the requirement for the experience of the police officers sent to inquire about the informants is high. Especially those sent on business trips to other places, basically they must be trained police officers, otherwise, what if they are sold?

300-plus people don't sound like much, it's equivalent to being replaced by elites.

Now, checking houses is the same problem. Sending a few weak chickens to turn over the data without results is useless.

But to get results, the three-place one-bureau set by Xu Tai-ning, at least another forty or fifty people are needed.

Xu Tai-ning is also rubbing his eyebrows, pondering.

It didn't take too long to consider. In the afternoon, Xu Tai-ning transferred the heavy responsibility to the three-place one-bureau, and naturally said: "Everyone sends 15 people, which can be considered an additional investment."

Several people who came to the meeting naturally resisted subconsciously: "Our bureau has really reached the limit. Now the parking lot is blocked, and the section chief is down to direct traffic."

"It's also good to send the section chief out, and there are fewer people parking." Xu Tai-ning didn't give a chance at all, emphasizing: "Everyone checks their own bureau. If there are fewer people, they can't keep up, which is definitely not okay."

He didn't say what would happen if it didn't work, but for such a big case, no one wants to be the one who drops the chain.

Representatives of other city bureaus also shouted: "Our cases are not few now. If we draw manpower again, daily work will be affected. Director Xu, please understand, let's use the existing manpower first..."

"No, doing such a big case, without any reserve force in hand, is reckless." Xu Tai-ning finished and persuaded: "I want the kind of old criminal police who can look at the data and check the case. The requirements are high, the tasks are not heavy. If the business police in your unit are not enough, it is also okay to draw a few from the organ, maybe it is better to use."

Several representatives of the city bureau were a bit stunned and a bit funny. Thinking about it, they all expressed their willingness to go back and ask.

Those who do front-line business always like to mock those who sit in the organ. But the work of the organ is not small. The daily workload may be greater than that of the business department. If it is sent down, it is equivalent to the army fighting, and the organ troops and guard companies are sent out, mainly trying their best.

Thinking of the scene where the bureau director and deputy bureau director might have to make tea and eat by themselves from now on, several representatives were vaguely excited.

It is Xu Tai-ning who makes party A live so humbly.

Jiang Yuan didn't care about these. He brought the clothes back and could only search for them one by one.

Doing technology is actually a very masculine job. The feeling of being bright and refreshing often lasts only for a moment, at most ten seconds, but to achieve this moment, it requires long-term cultivation and repeated, repeated, boring work.

Most technical work is very boring, and the moment of innovation and thinking explosion is always rare. Or rather, the more high-end the technology, the more the requirements for innovation and thinking explosion should be reduced, so that it can be increasingly popularized.

Jiang Yuan used forensic material science today, LV4 skill.

If you want to put a most simplified label on forensic material science, it is the forensic technology of finding DNA. To be specific, it includes blood, semen, milk, saliva, nasal mucus, urine, amniotic fluid, hair, nails, bones, teeth, etc., etc.

In short, scattered things on people are all within the scope of forensic material science research. Most importantly, forensic material science also needs to study and deal with the problem of evidence contamination.

Because most human tissues, once scattered, are basically contaminated. Like semen, the one in the condom may contain oil, or special bactericidal ingredients. The one on the ground has dust, the one on the wall has powder, the one that has been in the mouth has saliva, and the one on the paper has dander...

Like the former forensic doctor Niu, who specialized in the analysis and identification of living paper, it contains some forensic material science technology, and the level is quite high.

Jiang Yuan looked at the time, put a temporary skill +1 on himself, and started searching for dander in the clothes one by one.

His main search is still in positions like collars and cuffs, especially cotton and wool products, which are easy to find dander or hair in the gaps of a pile of fibers.

Finding pollen is a similar method, which is just a much lower probability.

And forensic material science is also the technology most often needed by lower-level county bureaus. Many things that cannot be done in ordinary laboratories often have a better result when handed over to higher-level laboratories. It has high requirements for technology and equipment.

Jiang Yuan now has both, but whether he can get the inspection material is another matter. ===== CHAPTER 543 =====
