When they arrived at the gate of the provincial bureau, the director of Xiu, the head of the criminal investigation team, and a technician had been waiting for a long time.

As soon as Bai Ke stopped the car, the director of the repair bureau came up to him.

Qin Yongmei was the first to get out of the car, and Director Xiu helped her: "Let's go! Comrade Yongmei, let's go to dinner." ”

"Oh, eat whatever you want, and get to work. ”

"Of course it's a casual meal, let's go. ”

Six people, three men and three women, walked together to the canteen of the provincial bureau.

When I arrived at the cafeteria, I walked directly into the small room.

Although it is a casual meal, it is also full of variety.

This journey is full of dust, and everyone is a little hungry, so there is no need to be polite.

While eating, the technician couldn't help but report the testing process to Sun Yuan.

Sun Yuan listened carefully and nodded: "Well, your operation process is fine." ”

Director Xiu smiled: "You see that we are old and comrades, and we don't forget to work when we eat." ”

Older than a woman in her forties.

Wears glasses as thick as the bottom of a bottle.

After chatting a few words, I realized that this old man was a medical doctor.

Like European and American countries, most of the earliest people engaged in DNA research in China came from the medical field.

It's just that this old Yu's position in the provincial bureau is a little embarrassing.

The provincial bureau is the common name of Bai Ke and Qin Yongmei.

In fact, it is also a city bureau.

It's just that Fengtian City, as a provincial capital, belongs to the sub-provincial treatment.

It is one level higher than a prefecture-level city like Blue City.

Therefore, Qin Yongmei and them are different.

The public security bureau of the provincial capital is called the provincial bureau.

The public security bureau of the blue city is called the city bureau.

The public security bureau in his own county is called the county bureau.

Therefore, the establishment of the provincial bureau is the same as that of the municipal bureau.

All kinds of technical personnel belong to the technical investigators under the criminal police brigade.

Logically speaking, DNA testers like them are also in the category of algorithmic medicine.

But he is older than a comrade, and he himself is a doctor of medicine.

The level of education is much higher than that of other veteran forensic doctors in the brigade.

It's not good to look good if you set a low position.

Director Xiu specially asked the higher-level leaders for instructions and set up a technical section in the criminal police brigade.

Let an old forensic doctor serve as the director, and Lao Yu as the deputy director.

After eating, everyone came to the laboratory together.

In front of everyone, Sun Yuan carefully checked the test report made by the technicians who were older than them.

"That's right, your results are accurate. ”

It is equivalent to saying that the murderer of the girl in red in the county town committed another crime in the provincial capital.

This is the third case.

These three cases occurred in the county seat in 1987 and 1990, respectively.

And this one is happening in the provincial capital right now.

The experts have affirmed that Director Xiu is both surprised and uneasy.

Surprisingly, this is not a headless case, it is traceable.

What is disturbing is that there have been three cases in a row, which can be characterized as serial murders.

And judging from these three cases, the murderer's methods of crime are becoming more sophisticated and bold each time.

This homicide in the provincial capital took place in broad daylight.

The murderer went directly into the victim's home, tied up the victim, raped and killed him.

Tossed back and forth for an hour, stepping in the footsteps of her family's return.

It's bold and arrogant.

Now that the experts have determined that the test results are fine.

Director Xiu, they will have to discuss the next step of the investigation.

Bai Ke and Sun Yuan continued to stay in the laboratory, while Qin Yongmei, the repair bureau and the captain of the criminal police went to the conference room together.

In the conference room, several other detectives had been waiting for a long time.

Director Xiu threw the inspection report on the table: "That's right, this case and the two cases in the county town were committed by the same murderer. ”

The captain of the criminal police said: "In other words, the murderer is likely to be from our provincial capital, but he should have relatives in the county." ”

Qin Yongmei nodded: "So, we couldn't find him when we sampled the DNA in the county seat." ”

Director Xiu said: "Then let's cross-screen, Comrade Qin Yongmei, you will delineate the scope." ”

The provincial capital has a population of nearly 6 million.

Qin Yongmei casually demarcated a range of 180,000.

However, it can be drawn in more detail, and strive to control the scope of suspicion within 1,000 people.

The first is people born between 1969 and 1959.

Male, blood type A, height between 170 and 180.

The most important point is that he has relatives in the county seat.

While Sun Yuan was communicating with the old Yu and their technicians, Bai Ke had already booked a plane ticket for her.

When the time was almost up, I drove her to the airport.

I saw her fly back to England.

Qin Yongmei had to stay in the provincial capital for a few days and continue to discuss the case with the repair bureau.

Taking advantage of the few days while waiting for his mother, Bai Ke went around.

Let's visit Zhuoma, Dr. Yang, and Guan Jian first.

Zhuoma is one year older than Bai Ke, born in 1967.

In 1988, she got married.

But over the years, the relationship between husband and wife has gradually cracked.

divorced after the Spring Festival this year, and Zhuoma lived alone with her two-year-old daughter.

Since the 90s, the divorce rate has gradually increased.

In the 21st century, the divorce rate of this wave of people born in the late 60s has reached more than 50%.

But he was born in a conservative family, and his personality is relatively conservative.

In this society of acquaintances, Dolma still feels a little unable to raise his head.

"Simply, you go to Baike to do it, it's not far from the provincial capital. ”

Guan Jian suggested.

"Yes," Bai Ke said, "it just so happens that my biotechnology company needs talents with medical biology backgrounds, so I can arrange a position for you casually." ”

Dolma also wants to leave this place, but considering that his father is getting older, he can't bear it.

"Let's talk about it. ”

After meeting Zhuoma and them, Bai Ke inspected several Jiangtao hotels in the provincial capital.

Jiang Tao Hotel now has more than a dozen branches across the country.

Among them, there are four in Blue City, two in Luda City, and three each in Kyoto and the provincial capital.

At the end of the 80s, due to severe inflation, the business of various restaurants was greatly affected.

However, Jiang Tao is deeply concerned about cost control and internal management.

I finally got through it.

Since last year, business has started to boom again.

The management system and management process of Jiangtao Hotel were established by Liu Qingtao back then.

I don't dare to say that it is leaky, but it does work.

The manager of each branch only needs to go to the county head office every month to report to Jiang Tao and check the accounts.

In their spare time, the management of the hotel, such as Jiang Tao, Liu Qingtao, Bai Ke, and Lu Laoer, they will check every once in a while.

Correct problems in time.

The white guest raided and checked around and found some minor problems that were prevalent.

For example, the waiter chats and chats about personal matters in front of customers.

This may seem like a small thing, but it feels like a diaphragm for customers.

Make it difficult for customers to feel at home.

Another example: the sanitary environment of the staff dormitory is a little dirty and messy.

As a staff member of a health place, if you can't do a good job of personal hygiene, how can you do a good job of collective hygiene in the unit.

Others like inconsistent hairstyles for employees.

For example, some boys have long hair, and some have mustaches.

Women have horsetail ties, and some have shawl hair, which is really varied, and so on

While checking, Bai Ke wrote down his experience.
