National Forensic Doctor

"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 then shared the information at the meeting.

The policeman assigned to the task force in Huo City said: "This shouldn't be difficult. The victim was involved in cash transactions. We will find all the properties that were traded in cash within three years before the incident. The volume of housing transactions in that year should not be large..."

Xu Taining pondered and said: "There is no guarantee that the house will be bought in Huo City."

When the police in Huo City heard this, they realized that there was nothing wrong with this logic. If the victim bought the house for himself, it was indeed possible that it was bought in Huo City, but what if it was not in his own name and was bought for a wild man?

If the wild man is the murderer, he has committed crimes in three places along the Jingyang Line, which proves that he is familiar with the three places, or at least the train lines in the three places. Then wouldn't it be possible to expand the scope of buying a house? To these three places?

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

Huo City and Qingbai City are fine. Two prefecture-level cities, how much real estate transaction volume they could have 20 years ago, but Changyang City, as the provincial capital, is different. Even 20 years ago, at least 10,000 real estate transactions were recorded every year. Start with the set.

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

"kindness?"

"Twenty years ago, the railway bureau should have provided welfare housing allocation, not necessarily in which city. We still have to consider that the murderer may have a railway background and may use this status to buy a house."

Liu Jinghui hissed, Xu Taining's logic was correct, but the funds were also lost in the water.

"Okay, this can be considered part of the investigation." Liu Jinghui felt that spending so much money was a bit too much. He is also someone who often presides over investigations. He also likes logic and is good at logical analysis, but he will definitely not spend this much money. Money.

These days, there are not many police stations willing to ask the King of Logic to help. If you continue to spend so much money, Party A will be in trouble.

However, Liu Jinghui couldn't stop Xu Taining from spending money. Moreover, he also knew that in these days, some Party A's were born with sexual tremors. If Party A's penis would tremble even if they spent a dollar, perhaps they would be afraid of someone like Xu Taining. I feel like spending hundreds of dollars is nothing.

Of course, Xu Taining's judgment was correct. The railway bureau's house and the welfare housing allocated a few years before the incident should all be taken into consideration.

In fact, it is more accurate to take all houses in the province into consideration. After all, you don’t know where Liu Limin’s boyfriend is from. What if he buys a house in his hometown? This is what Liu Jinghui thought, and his thoughts drifted away in a flash.

The next task is still important.

Xu Taining was also very busy.

This time's investigation is different from the usual investigation. The scale of the investigations he organized before was mainly reflected in the large number of personnel arrangements, task allocation, various logistical support, and work advancement.

This time, the scale of the investigation site he organized was not large. Although several clues were tracked at the same time, the number of people invested in each clue was only about a hundred people. This means that so far, Xu Taining has only invested three to four hundred people in the organization. Just people.

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

Faced with a murder case, the ordinary branch in the capital organized a 3,000-person investigation and play.

However, one characteristic of Xu Taining's investigation this time was whether he gave up or not.

To put it simply, the policemen sent out will not be able to come back for a while.

Regardless of whether they were checking real estate transactions now, or were tracking self-employed people in the market before, or all the people who had footprints near the scene, the people Xu Taining sent out to investigate would not be able to come back in a short time once they left the house.

These police officers, who are on business trips across the country, have to investigate the local situation as clearly as possible when they arrive at a place. The more this happens, the higher the difficulty and the longer the investigation will take.

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

The high-capacity, high-turnover model was forced to switch to a low-capacity, low-turnover model.

Xu Taining was also scratching his head over this.

To be honest, sending 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 requirements for experience of the policemen sent out to interview people with knowledge of the matter are much higher. Especially those who are sent on business trips to other places must be trained police officers. Otherwise, what will happen if someone sells them?

More than 300 people doesn't sound like a lot, but it's like they were all replaced by elites.

Now, house inspections have the same problem. Sending a few weak chickens to search for information is useless.

But if you want to work, Xu Taining has set up three places and one bureau, which requires forty or fifty people at least.

Xu Taining also rubbed his eyebrows and thought about it.

It didn't take long to think about it. In the afternoon, Xu Taining transferred the important task to the three places and one bureau, and said naturally: "Everyone contributes 15 people, which is considered as additional investment."

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

"It's good to send the section chief out, and there are fewer people parking the car." Xu Taining didn't give a chance at all, and emphasized: "Every bureau is checking each bureau, and there are too few people to go out. If 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 slipped up.

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

"No, it's reckless to handle such a big case without any reserves at hand." After Xu Taining finished speaking, he persuaded: "What I want this time is the kind of veteran criminal policeman who can check the information and investigate the case. The requirements are high. , the task is not heavy, if there are not enough operational police officers in your unit, you can just transfer a few from the agency police, maybe it will be more useful."

Several city bureau representatives looked a little stunned and a little amused. After thinking about it, they all expressed their willingness to go back and ask.

People who do front-line business always like to laugh at those who work in government offices. However, the work of the agency is not limited to young and old, and the daily workload may be greater than that of the business department. If it is really sent down, it is equivalent to the troops fighting. All the agency troops and security companies are sent out, and the main task is to do their best. .

Thinking about the scene where the directors and deputy directors might have to make tea and eat by themselves from now on, several representatives were actually a little vaguely excited.

It was Xu Taining who made Party A live in such a humble state.

Jiang Yuan didn't care about this. When he came back with the clothes, he could only rummage through them one by one.

Doing technology is actually a very manly job. The feeling of being glamorous and refreshing often only lasts for a moment, disappearing within ten seconds at most. However, in order to achieve this moment, it takes a long time of hard work and repeated boring tasks. work.

Most technical work is very boring, and there are always very few moments of innovation and creative thinking. In other words, the more high-end the technology, the lower the requirements for innovation and thinking explosion, so that it can become more popular.

Jiang Yuan used forensic medicine today, a LV4 skill.

If you want to put the most simplified label on forensic evidence, it would be the forensic technology of finding DNA. To be more specific, there are blood, rice fluid, milk, saliva, nasal mucus, urine, amniotic fluid, hair, nails, bones, teeth and so on.

All in all, the scattered things on the human body are within the scope of forensic evidence science. The most important thing is that forensic evidence science also needs to study and deal with the problem of contamination of physical evidence.

Because most human tissues are basically contaminated once they are broken into pieces. Just like the rice green liquid, the liquid in the bag may contain oil, or it may contain special sterilizing ingredients. There will be dust on the floor, powder on the wall, saliva in the mouth, and crumbs on the paper...

For example, the former forensic doctor specializes in the analysis and identification of household paper. He has some forensic evidence skills in it, and his level is quite high.

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

He mainly searched for areas such as the collar and mouth of clothes, especially cotton products. It was easy to find dander or hair in the gaps between a bunch of fibers.

The method for finding pollen is similar, but the probability is much lower.

Forensic evidence science is also the technology that lower-level county bureaus most often need to support. Many things that cannot be done in ordinary laboratories can often get better results if they are handed over to higher-level laboratories, which have higher requirements for technology and equipment. requirements.

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