Chapter 569 Arch

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

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

The policeman assigned to the special case team in Huo City said: "This should not be difficult. The victim made a cash transaction. We will find all the real estates that were traded in cash within three years before the incident. The volume of house transactions in those years should not be large..."

Xu Taining pondered and said: "It cannot be guaranteed that the house was bought in Huo City."

When the police in Huo City heard this, this logic was really correct. If the victim bought the house for himself, it is indeed possible that it was bought in Huo City, but if it was not in his own name, it was bought for a wild man?

If the wild man is the murderer, he has committed crimes in three places along the Beijing-Yangzhou line, proving that he is familiar with the three places, at least the train lines in the three places. Then, the scope of buying houses may be expanded to these three places?

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

Huo City and Qingbai City are okay. They are two prefecture-level cities. How much real estate transactions could they have 20 years ago? But Changyang City, as the provincial capital, is different. Even 20 years ago, at least 10,000 units were sold every year.

Xu Taining said, "There is also the Railway Bureau."

"Huh?"

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

Liu Jinghui made a "hiss". Xu Taining's logic was sound, but the funds were also thrown into the water.

"Okay, this is also part of the investigation." Liu Jinghui felt that it was a bit too much to spend so much money. He was also a person who often presided over the investigation. He also liked logic and was good at logical analysis, but he would never spend money like this.

These days, there are not many police stations willing to invite the King of Logic to help. If you spend so much money again, the client will definitely explode.

However, Liu Jinghui could not stop Xu Taining from spending money, and he also knew that these days, some parties are born masochists, who would tremble when they spend one dollar, but when they meet someone like Xu Taining, they might think that spending a hundred dollars is nothing.

Of course, Xu Taining's judgment is correct. The house of the Railway Bureau and the welfare house allocated a few years before the incident should all be taken into consideration.

In fact, it is more accurate to take all the houses in the province into consideration. After all, you don't know where Liu Liming's boyfriend is from. What if he buys a house in his hometown? Liu Jinghui just thought about it, and his thoughts drifted away in an instant.

The next task is still heavy.

Xu Taining is also busy.

This time's investigation is different from the usual investigation. The scale of the investigation he organized before is mainly reflected in the large-scale personnel arrangement, task allocation, various logistical support, and work promotion.

This time, the scale of the investigation he organized was not large. Although he tracked several clues at the same time, the number of people involved in each clue was only about 100. That is to say, so far, Xu Taining has only organized and invested 300 to 400 people.

This number is of course much larger than the general investigation in Shannan Province, but it is not a surprising number in the "investigation world".

When an ordinary branch in Beijing faces a current murder case, it is no different to organize an investigation of 3,000 people.

However, one feature of Xu Taining's investigation this time is that he never gives up.

In short, the police officers sent out will not be able to come back for a while.

Regardless of whether it is checking real estate transactions now, or tracking individual businesses in the market before, or all the people whose footprints appeared near the scene, the people Xu Taining sent out to investigate will not be able to come back in a short time once they go out.

These police officers travel all over the country. When they arrive at a place, they have to investigate the local situation as clearly as possible. The more so, the higher the difficulty and the longer the investigation time.

This is very different from Xu Taining's previous investigations.

The high-capacity and high-turnover model was forced to change to a low-capacity and low-turnover model.

Xu Taining was also scratching his head for this.

To be honest, getting 3,000 people to dig up corpses on the highway is not a very demanding job. There is always a way to dispatch 3,000 people.

Now, the police sent out to question the insiders have high experience requirements. Especially those sent on business trips to other places, they basically have to be trained police officers, otherwise what if they are sold out?

More than 300 people don’t sound like a lot, which is equivalent to replacing them with elites.

Now, the same problem applies to house inspections. Sending a few weak chickens to go, it’s useless to just look through the information without getting any work done.

But if you want to get work done, the three places and one bureau set up by Xu Taining will require at least 40 to 50 people.

Xu Taining also rubbed his eyebrows and thought about it.

Without thinking too long, in the afternoon, Xu Taining transferred the important task to the three local bureaus and said naturally: "Everyone should send 15 people, which is considered an additional investment."

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

"It's good to send the section chief out. There will be fewer people parking." Xu Taining didn't give them any chances at all, and emphasized: "Everyone should check their own bureaus. If there are fewer people, they can't keep up. It will definitely not work."

He didn't say what would happen if it didn't work, but in such a big case, no one wanted to be the one who failed.

Some representatives of the municipal bureau also said: "We have a lot of cases now. If we transfer more people, our daily work will be affected. Director Xu, please understand and use the existing people first..."

"No, it's reckless to handle such a big case without any reserve." Xu Taining also advised: "What I want this time is the kind of old criminal police who can check the information and investigate the case. The requirements are high and the task is not heavy. If there are not enough business police in your unit, you can transfer a few police from the agency. Maybe they will be more useful."

Several representatives of the municipal bureau looked a little stunned and a little funny. After thinking about it, they all expressed their willingness to go back and ask.

Those who do front-line business have always liked to laugh at those who work in the agency. But the work of the agency is also not small, and the daily workload may be greater than that of the business department. If they are really sent down, it is equivalent to the army fighting. The agency troops and the guard company are all sent out, and the main goal is to do their best.

Thinking about the scene that the director and deputy director may have to make tea and eat by themselves from now on, several representatives are actually a little excited.

It is Xu Taining who makes Party A live so humbly.

Jiang Yuan doesn't care about these. He can only search for clothes one by one when he comes back with them.

Being a technician is actually a very masculine job. The glamorous and wonderful feeling is often only a moment, which disappears in a dozen seconds at most. But in order to achieve this moment, it takes a long time to cultivate and repeat some boring work.

Most technical work is very boring, and there are always few moments of innovation and explosive thinking. In other words, the more advanced the technology is, the lower the requirements for innovation and explosive thinking should be, so that it can become more popular.

Jiang Yuan used forensic evidence today, a skill of LV4.

If you want to give a simplest label to forensic evidence, it is the forensic technology of finding DNA. To be more specific, there are also blood, vaginal fluid, breast milk, saliva, nasal mucus, urine, amniotic fluid, hair, nails, bones, teeth, etc.

In short, the scattered things on the human body are all within the scope of forensic evidence research. The most important thing is that forensic evidence also studies and deals with the problem of contamination of physical evidence.

Because most human tissues, once scattered, will basically be contaminated. For example, vaginal fluid may contain oil or special bactericidal ingredients in the set, there is dust on the ground, there is powder on the wall, there is saliva in the mouth, there is crumbs on the paper...

For example, the former Niu forensic doctor, who specialized in the analysis and identification of daily paper, has some forensic evidence technology in it, and the level is quite high.

Jiang Yuan looked at the time, attached a temporary skill of +1 to himself, and began to search for clothes one by one.

He mainly searched for places such as the collar and cuffs of clothes, especially cotton and wool products, where it is easy to find dandruff or hair in the gaps of a pile of fibers.

Finding pollen is a similar method, but the probability is much lower.

And forensic evidence is also the technology that the lower-level county bureaus most often need to support. Many things that cannot be made in ordinary laboratories can often get better results when handed over to higher-level laboratories. It has higher requirements for technology and equipment.

Jiang Yuan now has both, but whether he can get the test materials is another matter.
