Chapter 543: Bald Attack Team Attacks

Changyang City Criminal Science Center.

Jiang Yuan took the clothes he brought back and took the high-speed rail directly to Changyang City.

These clothes have been cleaned and searched several times. It can be said that it is already very difficult to find evidence at the level of hair from these clothing fibers. Even if found, most of them are contaminated hair of outsiders.

Jiang Yuan's expectations are placed on dander, especially the woolen coats, wool and cashmere sweaters, woolen sweaters, woolen hats, and scarves he brought back this time.

Although these clothes have also experienced multiple searches, they are not suitable for water washing, and they don't need to be cleaned frequently. The Liu family didn't take them to dry cleaning after Liu Limin died, so they are the most hopeful to find dander.

Secondly, the gaps in these wool and wool products have a certain space to accommodate dander, especially in close contact, such as hugging, etc., dander may go deep into the fibers. Only in this way is the dander found most valuable.

This difficulty can be said to be hell-level.

Therefore, although facing a basket of clothes, half of the technicians in the Changyang City Criminal Science Center began to tremble.

The remaining half won't do it.

Wan Baoming insisted on gathering people together.

Jiang Yuan stood in the middle of the laboratory and said: "Everyone has worked hard. The task this time is relatively heavy. We must extract the dander in the clothes as much as possible. It is better to be slow, and definitely don't miss it."

Jiang Yuan didn't plan to do it alone. Don't look at these twenty-something clothes, hats, and scarves. Three people working together will be tired to death.

The workload of doing this might be greater than the workload of doing pollen, which is similar to the concept of micro-evidence.

At the current stage of doing pollen cases, if you want to make it a bit easier, you often use a washing method to wash the pollen off the objects. Because pollen is acid-resistant and corrosion-resistant, even after the ravages of a washing machine, the pollen evidence will only be rinsed into the water, and then you can find a way to extract it using a centrifuge.

If you do this with dander, it's okay if the quantity is large. If the quantity is small, the loss is too great.

Wan Baoming talked to Jiang Yuan in advance, knowing that it was a needle in a haystack, and specifically emphasized: "The case is very important. Everyone cheer up. Let's divide into AB groups. The two groups cross-check. By then, the group with the most omissions will be punished with three cups of wine at dinner!"

"I will treat everyone to roasted whole lamb at dinner, with plenty of craft beer, and paired with Moutai." Jiang Yuan activated the money ability.

The technicians were suddenly excited. In this year, no one lacks that little oil star, but it is still a very happy thing for everyone to eat roasted whole lamb together, drink some Moutai and beer.

Furthermore, this was helping Jiang Yuan from Ningtai, and since the man was grateful enough to treat them to a meal, everyone was naturally willing to roll up their sleeves and get to work.

Not to mention anything else, leaving a good impression on Ningtai Jiang Yuan, asking for advice later, or having any technical collaboration, is excellent to get a familiar face.

Technical bigwigs may be worse than political bigwigs, but as long as technical bigwigs don't die, they can always exert residual heat, which is also quite awesome.

Changyang City's Criminal Science Center was originally the largest criminal science and technology team in the province, larger than the scale of the Provincial Department. During this period, those who didn't understand micro-evidence did other projects and tasks, and those who understood micro-evidence gathered together, and the laboratory was also lively.

Jiang Yuan also called Huang Qiangmin, used the money owed by the Changyang City Bureau, bought a batch of head-mounted microscopes for the Changyang City Bureau first, and then distributed them to everyone.

A group of people put on head-mounted microscopes and invested in the great task of searching for dander in the gaps.

The dander searched out was sent directly to the laboratory to run PCR.

Through dander, especially scalp dander, to do DNA identification, this is a technology that the Ministry only carried out around 2008. It was promoted to the Shannan Provincial Department until 2010, and it was promoted to various city bureaus and county bureaus, which was almost around 2012.

And before this, if it wasn't for criminal police who paid special attention to this knowledge, they wouldn't collect scalp dander at all.

Knowledge update is a very long process. For criminal police, not to mention the heavy daily tasks, the knowledge that needs to be updated is also very much. It is normal to listen to the technical explanation of smart locks today, and not to the sixth explanation meeting of DNA the day after tomorrow.

From this perspective, it is still possible to find the boyfriend's scalp dander from the victim's clothing.

It's just particularly expensive for the eyes.

A group of technicians worked, and soon there was no sound.

On the other side, Xu Tai-ning was also tired enough.

Three places and one bureau, there is a hall and a ministry above, although the latter two appeared in a cooperative posture, they also had requirements, and they had to report from time to time. Xu Tai-ning himself was a senior police officer sent by the Provincial Department, and the requirements of the department for him were even higher.

Furthermore, the report cannot be just a hollow description, it must also have substantial data.

Even if the leader just listens, data information cannot be less.

And when it comes to paying money and people, the three places that pay the big head are becoming more and more difficult to cooperate. The Provincial Department and the Ministry only take care of supporting, and how much money is paid below, they pay according to the proportion. Even so, the Provincial Department and the Ministry have started to speak badly.

At this time, if it were an ordinary leader, he might seek support. Xu Tai-ning is not like this, he is all using PUA.

"Huo City has paid 30%, you add a little more, and I will conclude the report."

"Yes, Huo City added, you also add? Good, then you are still ranked first. Don't worry, the report remains the same."

"En, you must be specially marked here. In fact, I suggest using people to exchange for funds. It is more cost-effective to change now, so as not to want to use people to exchange later, the price ratio has changed."

"Laboratory time is counted, no problem, you can open a list later, but for the funds, you have to make up a little more... hey, it's okay to fold into the laboratory funds later, but everyone has paid now, only you haven't paid..."

"Hello hello, the laboratory funds of the Changyang City Bureau have been paid, look at your side..."

Just task management, although there are several lines to manage, Xu Tai-ning doesn't feel too difficult, but PUA various units... actually it is not very difficult.

Xu Tai-ning, who stood in the conference room, danced and was like a fish in water, his voice was like a bell, he kept waving his arms, shouting loudly, as if he were a football coach, as if everyone was pushed by him.

But various units are also really pushed by him.

On the evening of the second day, a new clue was screened many times and finally became the only one.

Xu Tai-ning checked again and again, and then didn't even care about the leaders of the Provincial Department, and couldn't wait to call Jiang Yuan. Participating in Jiang Yuan's case twice recently, Xu Tai-ning belonged to the battle array but returned without success, and the grievance in his heart was unspeakable. At this moment, he finally felt the feeling of raising his eyebrows.

"Captain Jiang, we may have found someone." Xu Tai-ning's voice could pass through the glass window and reach outside the conference room.

"Found? How did you find it?" Jiang Yuan was also inexplicably surprised.

Xu Tai-ning was proud and said: "Speaking of which, it is simple. The real estate transaction list of the three places and one bureau was pulled out. In the three years before the incident, there were only four digits of people who bought houses with cash in the market. Comparing it with the transfer records in the victim Liu Limin's list, one person came out."

He said it easily, but thinking about the difficulty of the clues being pulled all the way, a single county bureau might not be able to support it until this moment.

Xu Tai-ning was full of pride: "This person is named Wang Shiji. You say it is a coincidence, his family is really a railway family, Changyang City people, uncles and brothers, uncles and grandfathers are all on the railway..."

"Have you caught anyone?" Jiang Yuan asked busily. Just looking at these details, it is enough to bring Wang Shiji back for interrogation."

"I'm about to set off." Xu Tai-ning laughed twice, covering up his embarrassment.

He called Jiang Yuan for the first time this time, where did he have time to order the arrest.

Hanging up the phone, Xu Tai-ning immediately called Wu Junhao, asking his Bald Attack Team to prepare to set off and go straight to Changyang City.

Then, Xu Tai-ning called the Provincial Department and the Changyang City Bureau again.

By the time Wu Junhao's Bald Attack Team arrived and joined the police officers of the Changyang City Bureau, it was estimated to be late at night, but no one raised an objection because of this. ===== CHAPTER 544 =====
