The signal base station is located in the center of the field, rarely visited and protected. Although it has gained a lot in the past thirty days.

Nine shoe prints were extracted on site, belonging to two people.

The two pairs of shoe prints are side by side, more than 80 cm apart, and they all the way north and disappear on the edge of the field leading to the highway. The footprints are deeper, and one person on the right leaves deeper, especially the left footprints.

The outdoor unit of the air conditioner is so large and so heavy that it is difficult for one person to move it away. One end is heavy and the other end is light. It can basically be determined that the suspect is left behind, and it is two people who committed the crime.

Six cigarette butts were found on the site, and the brands on the filters were clearly visible. Five of them cost about ten yuan per pack, one of which was a low-end cigarette, two yuan per pack, and farmers and migrant workers smoked more.

...

According to regulations, on-site inspections require finding witnesses. There is no village in front of the village and the shop behind it. There is no car on the north road for a long time. I can’t find it in a while, so I can’t find it.

"The person who sent the police was too irresponsible. The traces on the scene were so obvious that it was impossible to be invisible. He did not notify the technical squadron to come for investigation."

As soon as he got on the car, Wan Peng couldn't help but mutter.

Li Wen often deals with the technical squadron of the branch. He is not surprised anymore. He tightened his coat and smiled bitterly: "It's not that the police officers didn't see the footprints, but they don't believe that they can solve the case through the footprints. They are only interested in fingerprints on the scene, and the rest are nonsense. Besides, there are a few people in the technical brigade of the branch, so the notification may not be available."

"How many types of shoes are there now? It's not a major case. Who would investigate the suspects wearing similar shoes for an outdoor unit of an air conditioner?"

DNA solving cases is out of reach for grassroots police, and on-site inspections are just as "high-end" for grassroots police.

For the theft case with a small case value, come and take a look and make a few records. There are witnesses and clear suspects. If you have the conditions to solve the problem, check it out. If you don’t have the conditions, just put it aside. After all, resources are limited. Grassroots police force is tight and there is not much funding. It is impossible to invest too much manpower and financial resources in a small case.

Big cases will be solved, and small cases will not be solved, and ordinary people will still have opinions.

Han Bo stretched his arms and turned around and said, "Everyone, in the future on-site investigation, physical evidence inspection will change from major cases to common cases. In fact, many major cases are solved through small cases. More importantly, if the fingerprint database of veterans and the future DNA database want to truly play a role, they cannot be separated from the early basic information collection."

"Team Korean, I know the importance of basic information collection. Do so many technical police officers in the public security bureaus of key districts and counties?"

"When I finish my work, I will participate in the civil servant recruitment, interview candidates from ordinary universities, go to the provincial police academy, and recruit people from the Public Security Bureau. The technical squadrons of the three branches should be fully equipped, reaching 20% ​​of the total number of criminal police officers. Six county bureaus are in difficulty. Although several bureau leaders are very supportive, there is too much work to do when it comes to staffing, and this year can only solve some of them. Let's find a way to find a way for the remaining personnel gap."

The "Young Marshal" is completely different from Xing Da's busy work. He is considering the construction of Quannan-Hong Kong criminal technology units. But then again, Xing Da is just the technical team leader, not the deputy team leader, as long as he manages the technical team well.

"Korean Team, how many of our teams will recruit?" Wan Peng was not interested in how many newcomers the district and county public security bureau recruited this year, but only cared about his own unit.

"Five or six, mainly computer professionals."

Han Bo lay on the back of the chair, smiling at them and said, "The county bureau's technical squadron does not have enough staff. From the perspective of unit construction, you can wait, but from the perspective of case handling needs, you can't wait. You are all technical backbones. Are you interested in going to the grassroots level to serve?"

"On a job?"

"It can not only solve the urgent need for insufficient staff, but also play the role of teaching and helping the city bureau to use the advantages of posting and posting to help the municipal bureau promote the "technology-strengthening police" strategy. To give a simple example, we will build a fingerprint database and a DNA database for criminal officials. It is completely different from no one at the grassroots level. Information collection will be more comprehensive, and other tasks will be better connected than now."

The technical brigade is not that there are too few staff members, but too many.

The Criminal Technology Center of the Nangang Municipal Bureau in the future will become a hospital-like institution, concentrating resources to create forensic pathology, forensic physical evidence, physical and chemical tests, fingerprint databases and DNA databases for criminal personnel, psychological tests and electronic physical evidence.

Leave twenty backbone, and other positions to recruit civilian positions as much as possible, so as to sink valuable police forces to the front line, and no longer appear in the same spot as they are now, and become a technical support and authoritative appraisal department.

People walked to the high places and water flowed to the low places. They stayed in the municipal bureau. Who would like to go to the grassroots to suffer? Wan Peng and the other four were stunned.

Han Bo was prepared and said with a smile: "The bureau leaders and detachment leaders attach great importance to it and support it. If you go on duty, you will not let you be ordinary technical police officers, all of them will be the deputy squadron leader. It will last for three years. After the term of office, you will be promoted to the deputy chief clerk. You will be willing to stay at the grassroots municipal bureau to coordinate and be entrusted with important tasks when you come back."

It is too difficult for a technical policeman to be promoted, and Director Lu is still in the stock market.

Wan Peng was moved, but he had to discuss such a big deal with his family, and he looked reluctant to speak but stopped. Li Wen and the others were the same, and they didn't know what to say for a moment.

"You guys think about it, think about it and tell me."

At the same time, the "old coach" was looking at the report submitted by the eighth group with a stern face.

After five days of investigation, there are more and more steps to investigate, but fewer and fewer suspects.

There is no time to commit the crime, and it is impossible to get directly eliminated by explosives. If you are not sure about eliminating the blood samples, you will be sent for inspection. As a result, one of them is not comparable. There is no more inspection next, and the investigation work is in a deadlock.

"The speculation of Lao Wei and Jin Yang Cheng's civilization detection team makes sense. There are no shoes wet at the riverside station. It is not uncommon for unprofessional people to use lightning tubes to cause accidents. The suspect is very likely to have been injured. It may not necessarily be related to the theft of air conditioning outdoor unit that they mentioned, but the line between hospitals, clinics and clinics can still be checked."

Faced with this stupid explosion, Deputy Director Tan, who guided the investigation, organized the investigation and participated in the investigation of thousands of major cases, was also helpless and could only do whatever he wanted.

"Yes, organize people to check. Lao Shuai" didn't sleep well for five days and five nights, his beard was unshaven, his eyes were covered with blood, and he lit another cigarette.

The public security in the world is a family, and some of the names do not match the truth.

The criminal police in the world are a family, without any dispute.

Deputy Director Tan also served as the captain of the Criminal Investigation Detachment. He is very familiar with Wei Guoqiang and has always had a good relationship. An old friend of more than ten years ago felt very uncomfortable and urged him: "Old Wei, I don't know when this case will be done. Go and sleep for a while. If there is news, Comrade Changqing will report it in time."

"Wei Detachment, I'll deploy the hospital line. You can listen to Director Tan, so hurry up and go to bed."

I feel dizzy and can't stand it anymore.

Wei Guoqiang nodded slightly and stood up and said, "Okay, you stare at me, I'll go next door for a while."

...

At 12:24, Cheng Wenming received the second order since entering the 01.01 major explosion task force, asking him to return to the project command center immediately, and the hospital line was taken over by criminal police from three sub-districts in the city who were familiar with the situation.

When they arrived at the traffic police squadron, the logistics support staff had packed up an office.

"Comrade Cheng Wenming and Comrade Jin Yang are on his way back to the command center. From now on, you two will be responsible for checking the suspicious people who have been treated in the city. This is the list of police officers involved in the investigation and contact information. You have served as the captain of the criminal police brigade or squadron leader, and have rich experience in handling cases. I don't need to explain what to do next."

This is just one of the many lines being investigated. The leader is very busy and put down the list and left.

From front-line investigation to sitting in the office to directing investigation, this change is a bit big, and Cheng Wenming feels like he is dreaming.

There is no need to explain what to do. First, contact the police officers who checked the front line according to the mobile phone number on the list to count how many medical institutions there are in the three districts, local, military, and state-owned enterprises. As long as one of the medical services is provided, it cannot be missed...

He was so busy that Han Bo, who had just returned to the technical brigade after the investigation, was not idle.

After lunch in two, the three of them assigned tasks to the technical police at home.

A group of people checked the detachment files to see if the footprints extracted today can be compared with those extracted at the crime scene in the past three years. The other three groups took the footprint photos to the criminal police team of the three branches and compared them with the footprints they had previously extracted.

Arrange everything, change into a white coat, and extract six cigarette butts, especially the DNA that may be left behind on low-end cigarette butts.

"You stayed up until after 3 o'clock yesterday and lie on the table and sleep for a while. I'll do it and leave it to me."

"Yes, Team South Korea, this is another thunderous-policy."

"Okay, I'll doze off."

The old classmate was a "crazy man". Tian Xuewen picked up the cigarette butt and muttered while operating: "You can think of it by extracting DNA from the failed thunder tube. This is something Xiaolei doesn't know. If Xiaolei knows it, she doesn't know what she will be worried about. You can't do this in the future. You have a wife, a family, and a child right away."

He said that it means he didn't say anything. He had fallen asleep. He hadn't slept well like the "Old Shopping" in the past five days. He was too tired and sleepy.

Li Jiaqi was afraid that he would catch a cold, so she hurriedly found a coat to help him prepare it.

Tian Xuewen turned around and looked at it, shaking his head with a wry smile.

I don’t know how many parts of the test materials have been tested these days, but Tian Xuewen’s extraction speed is several times faster than before. In less than half an hour, he put six test tubes into the inspection tray.

Automatic inspection, all you have to do is wait.

Look, let me look at you, Li Jiaqi was embarrassed to read it, so she hurriedly picked up a book and sat quietly aside.

The man is married when he is old and the woman is married when he is old. He is over 20 years old and his sister-in-law has already made it clear. Tian Xuewen has no shame and leaned on the test bench and smiled: "Jiaqi, Director Zhao asked me to take my resume to the People's Hospital tomorrow morning."

"You have to think about it."

"I've thought about it, my family has no objection. Do you have time during the Spring Festival? If you have time, can you..."

There was a person lying beside him, saying that these were appropriate?

Li Jiaqi's pretty face was flushed with shame, but her heart was happy. The two of them whispered love like thieves. Time flies so fast that the six samples from the genotype meter were analyzed unconsciously.

Work is important, so you can’t delay Brother Han’s affairs.

Tian Xuewen sat in front of the computer and picked up the mouse and clicked it. Suddenly his eyes lit up. He was afraid that he would read it wrong, so he took off his glasses and rub it on and looked at it. The more he looked, the more excited he became, and he was so excited that he couldn't get more excited.

"Brother Han, Brother Han, where did you find this test material?"

"What?" Han Bo woke up in shock and yawned forever.

"You can see it yourself."

I searched for it without any effort to find it!

Cheng Wenming had been unlucky for so long, but he didn't expect that his luck would come and he could not stop him.

Han Bo was ecstatic and took out his cell phone in a hurry and called the "Old Shopping" phone number: "Wei Detachment, Wei Detachment, I, Han Bo, have matched and joined forces. The suspect is the one who steals the outdoor unit of the air conditioner of the base station of the mobile company. He is not a single person committing the crime. At least two suspects, one of them is likely to have been injured on the forehead."

With target locked, the next thing will be easier.
