At 7:30 in the morning, Cheng Wenming limped to the Criminal Police Detachment to work half an hour earlier, just like in the past few months.

Two years ago, this was the Technical Investigation Detachment of the Nangang Public Security Bureau. There are three names for external purposes, namely "Nangang Public Security Bureau Physical Evidence Inspection and Appraisal Center", "Nangang Public Security Bureau Forensic Appraisal Center" and "Nangang Public Security Bureau Criminal Science and Technology Research Institute".

Later, the bureau assigned criminal technology to the management of the Criminal Police Detachment, and independently set up an operational technical detachment. The Criminal Police Detachment moved from the Municipal Bureau to work here, and the technical reconnaissance was also moved away.

The office of the Technical Reconnaissance Brigade that year became the office of the detachment leader, political commissar, deputy detachment leader and several departments.

Considering that Cheng Wenming was unable to move, the detachment leader arranged his office on the first floor, diagonally opposite the office of Zhou Suying, the deputy captain in charge of the Criminal Technology Center.

"Cheng Da, I'm here so early again. Please slow down and leave this to me."

"It's not too early, I'm going to send my child to school. I'm walking from school at exactly 7:30."

The police officer on duty snatched the rag and helped clean the office while sighing: "Think about the pressure on the child now is so great. His schoolbag weighs more than ten pounds, and he has so much homework every day. He has to go to school at 7 a.m., and some Sundays have to make up for the lessons, which makes the child breathless."

"Yes, I was not so tired when I was in school. I remember to play all day."

Cheng Wenming turned around and smiled, put the crutch in the corner of the wall, opened the cabinet and started to change into police uniforms.

The body recovered well, from being unconscious on the lower body, who could only live in a wheelchair, but could not take care of himself. He recovered to being able to stand up with crutches, to being single crutches, and then to being on a cane. In the eyes of the doctor, he still felt slow, and felt that limping to get off work with a cane every day, walking on the road would affect the image of the people's police, so he wore casual clothes outside, and only changed into police uniforms when he arrived at the unit, and he refused to apply for any disability certificate.

To put it bluntly, the chief clerk is the chief clerk.

There are so many functional departments in this building, and there are not too many regular departments, and there are several deputy department-level leaders, but his regular department is different from other regular departments. As a first-level hero and model in the national public security system, not only the department leaders have an impression of him, but the leaders of the Ministry of Public Security may know him.

The detachment did not arrange heavy work for him, clean and turn on water, and everyone rushed to do things like doing it, and would not let him do it. The police on duty quickly finished the hygiene, called boiling water to pour him a cup, and confirmed again that there was nothing to help, so they returned to the duty room in the foyer to prepare for handing over the shift.

It feels really bad to be regarded as a disabled person, but they are also kind-hearted.

He insisted on doing some things within his ability before, but he always fought red in his face. Cheng Wenming didn't want to be too pretentious, so he simply let it go.

It doesn’t matter if trivial matters, you must do a good job.

The leader did not arrange specific work, but just asked the serious case brigade to help. Cheng Wenming did not want to become a "giant panda" of the detachment and even the municipal bureau. He took the initiative to take the study and analysis, guided or organized the work of solving major accumulated cases and difficult cases in the city, and drowned himself in the mountains of case files and materials, and lived a fulfilling life.

"Master, I'm sorry, I'm late again!"

Just after pulling out a stack of materials from the file bag, a young policeman with a tall figure, fair skin and a little delicate appearance ran into the office panting.

Zhong Xiaoming, a top student in the Criminal Court, started working last year. He turned out to be in the Hong Kong Branch. The leader of the detachment felt that Cheng Wenming was too busy to be responsible for so many things and was in poor health, so he transferred the young man from the branch criminal police brigade to serve as an assistant.

Old comrades should be taught and helped, while new comrades should study humbly.

Like other departments, Zhong Xiaoming became Cheng Wenming as his teacher as soon as he was transferred to the detachment. There were only a few heroes and models in the city's public security system. Not everyone has the chance to become heroes and models. Many new comrades were envious and said behind their backs that this brat is lucky.

"It's not too late, it's not yet working hours."

Cheng Wenming looked up at the wall clock on the wall, put down the case file and told him to have breakfast first. The young man was sleepy and would not get up until around 7:30. The same was true for the person in front of him. He was in a hurry to go to work every day and had no time to eat. He always bought it on the road and took it to his unit to eat.

Zhong Xiaoming smiled awkwardly, pulled open the plastic bag and swallowed it voraciously.

Cheng Wenming and Zhong Xiaoming have a "Ming" in their names.

The nicknames "Da Ming" and "Xiao Ming" were nicknamed "Er Ming" of the Criminal Police Detachment. The two parties involved did not know that the colleagues in the building, including the leaders, had spread.

"Chengda, morning."

Zhou Suying was at work and knocked on the glass door to greet her "neighbor".

Cheng Wenming suddenly remembered something, got up and asked with a smile, "Captain Zhou, Dawn, Zhou, I'll ask for some information, have you ordered the restaurant where we had dinner last week?"

"I don't have Dafu Restaurant, Lao Chen should have it. His house is close to you, so everything is arranged there."

"I'll ask Chen Da later."

"Why, there is a happy event?"

"The child is still young, what good things can my family have? An old comrade called in the morning and said he wanted to send his lover to the first hospital for examination. The hotel is not far from the first hospital in the city. I plan to invite them to a meal at noon."

Time is really a "killing-pig-killing knife", which can make people forget many things.

How long has the old leader been transferred? Apart from some "old people" in the technical brigade back then, there are not many people who can remember the name Han Bo now.

Zhou Suying simply walked into the office, followed "Xiao Ming" who was greeting him, nodded, leaned against the filing cabinet and asked curiously: "Old comrade-in-arms in Liangzhuang?"

"He has never worked in Liangzhuang Police Station, but he has something to do with Liangzhuang. In the past, the Fourth Criminal Police Squadron of Sigang County Bureau was managed by criminal cases in several townships in Dinghu, Liangzhuang. He worked with me for several years in the Fourth Squadron, and later transferred to the police station to work until now."

"Old comrade!"

People's encounters are really different. Cheng Wenming sighed: "I, Wang Yan, Xiao Ren and others who were later transferred to Liangzhuang have been in the management position one after another. There are seven or eight deputy directors, two of them are already deputy directors, one is the captain of the detachment and the other is the director of the county bureau. The person who came today failed to catch up. He has been an ordinary policeman. He has worked hard for nineteen years and cannot even be beaten. Ten years ago, he is still 'two cents' and has never been 'shoulder' since he started working."

It is difficult for public security to be promoted. This situation is very common. How many people can't even make it a deputy chief clerk until they retire.

Zhou Suying also has such old colleagues and comrades-in-arms. It feels bad to think about it, so she immediately changed the topic: "Cheng Da, old comrades-in-arms bring their lover to see a doctor. You should call Jiaqi. Her lover Dr. Tian is in the first hospital of the city. It is definitely different from having an acquaintance or not. She can do less unnecessary examinations and spend a lot of money less in vain."

It is difficult for public security to be promoted, and it is even more difficult for doctors to make a name for themselves.

Li Jiaqi's lover Tian Xuewen, who is in confinement at home, has a master's degree like Director Han. Director Han is already a deputy director at the department level. He is also an ordinary doctor at the First People's Hospital of the City. It is said that he was qualified to prescribe someone at the end of last year.

China is a society of human relationships, and no matter what you do, you want to find an acquaintance.

Cheng Wenming was no exception, laughing and said, "I didn't look for Jiaqi, I was looking for Director Zhao."

Zhou Suying, the person he was looking for, had heard of, the daughter-in-law of Secretary Liangzhuang, the chief physician of the Municipal People's Hospital, had an extraordinary relationship with the old leader's family.

"I almost forgot that with Director Zhao's relationship, Dr. Tian really has to stand aside."

Zhou Suying laughed and talked about the old leader with interest: "By the way, I called Xiaolei yesterday and she said she went to Hong Kong with Director Han. She cared about Jiaqi more than me, and said don't rush to let Jiaqi go to work, which makes me look like a black-hearted capitalist."

"She is Jiaqi's sister-in-law, and she is almost the same as her biological sister-in-law, so of course she cares about it."

"Yes, can't you let Jiaqi be in Binjiang Community?"

While chatting, Fang Hailong, director of DNA Laboratory, hurried over with two test reports. As usual, he was still wearing a white coat and still had a strong smell of disinfectant.

"Cheng Da, Zhou Detachment is here too!"

"What's the matter? Look at what you're anxious, just talk about it slowly." Zhou Suying smiled and stood up straight.

Fang Hailong handed over two DNA maps and said excitedly: "The two leaders, Xiao Liu, who just came to the internship, did not do anything seriously. He uploaded an irrelevant DNA information into the missing children of the Ministry of Public Security and their parents' DNA database. Unexpectedly, he missed the match and compared this."

"What does it mean?" Cheng Wenming saw this and asked the key point directly.

"Cheng Da, this is the DNA classification of the nameless corpse you brought back from Dongshan last year. This is the DNA classification of a missing child father in Zhejiang Province."

Cheng Wenming was stunned and suddenly felt ecstatic!

4.19 Case, the murder case that was inserted into a bamboo pole, was founded in order to find out the identity of the corpse floating in the water. After a thousand miles of hardships, the victim was named Jiang Xiaohong, but it did not help in solving the case. This incident once became a laughing stock for comrades for a long time.

Cheng Wenming calmed down and asked anxiously: "Is it the same person?"

"no."

Fang Hailong pointed to the map and explained: "These two DNA analyses have many similarities. From a genetic perspective, they should be related by blood. The two leaders were not transferred to the detachment at that time. Maybe they didn't know that the first murder case that our laboratory helped solve. When the equipment arrived home, the Han Bureau successfully locked a murderer in this way."

A child in Zhejiang Province is missing and is very likely to be abducted by human traffickers. Therefore, the public security organs collect DNA from his parents to facilitate searching and confirming the identity of the abducted child.

There are many missing children, and China is so big, and it is very high to establish a "anti-trafficking DNA database". Can children be found in this way and reunite with their children really depend on luck.

However, since the national public security organs launched a special "anti-trafficking" struggle and established the "DNA database for missing children and their parents" in 2000, a total of tens of thousands of samples have been inspected, and their biological parents have been found for 233 abducted children.

These are not important, at least not important to Cheng Wenming at this moment.

The mystery that has bothered him for several years and may have been bothering Han Bo for several years has finally been revealed. He held the DNA map tightly and said in an almost trembling voice: "Team Zhou, I seem to have mentioned to you the strange case of water drifting that Liangzhuang Police Station had encountered. From the accent, Zou, who took Jiang Xiaohong to elope, but disappeared for no reason after Jiang Xiaohong was killed, should be from Zhejiang Province.

From these two maps by Director Fang, we can determine that the corpse discovered by Dongshan’s colleagues last year should also be from Zhejiang Province. When I visited and asked in Dongshan, I learned a situation that Zou was originally traveling with another fellow villager to play cotton. Later, he said that the fellow villager had something to go home and asked Jiang Xiaohong, who had nothing to do at home, to help him and elope with his relationship."

"Zou told the villagers a lie, and another cotton-punk person didn't go home. The truth was that he killed him and buried his body near the victim's house!"

"So he kept sneaking after taking Jiang Xiaohong to elope, so he didn't dare to call the police after discovering that Jiang Xiaohong was missing or killed, but chose to escape."

A mystery that almost made him crazy finally emerged. Zhou Suying was very happy for him from the bottom of her heart and couldn't help but smile: "There is a case in the case, and this case is quite strange."
