Chapter 07 The family talks about wine to work, and the red sleeves add fragrance to learn technology

When I got home, when I went downstairs, Wanfang saw me from the living room window, and kept waving to me, I hurried upstairs, and Wanfang was already waiting at the door, taking my hand and entering the house, and saying as she went:

"On this first day of work, I'm tired, the food is almost cooked, and my mother is cooking."

Walking into the living room, my father-in-law spoke:

"Son, how did you feel on the first day of work in the Criminal Investigation Brigade?"

"The case was solved again today." I said happily, handed my father-in-law a few cigarettes that I had brought back, and said:

"Dad, this is a cigarette politely given by Secretary Wang and others, you take it and smoke it."

"Okay, I'll take this cigarette. You've solved the case on your first day on the job, okay, that's a good start, let's celebrate! The father-in-law said happily.

"Okay." I replied.

Wanfang ran to the kitchen in a hurry, and then, came out with the dishes in both hands, and her mother-in-law also came out, smiling, and holding the dishes in her hands.

"Mom, you've worked hard, let me serve the food." I said hello and took the plate from my mother-in-law.

"Son, I heard that you have solved the case again, okay, let's listen to you while eating." Mother-in-law said with a smile.

Soon, everyone was sitting at the table, and my mother-in-law made a big table full of dishes, which was very hearty, and I filled everyone's wine glasses.

The father-in-law raised his glass and said:

"Come, everyone drank this glass of wine to celebrate Ah Liu's work in the Criminal Investigation Brigade and solving a big case!"

The family happily finished their glasses of wine.

"Mom and Dad, thank you, and I will also toast you with a glass of wine." I stood up and said.

"Son, sit down, family, what are you polite about." The mother-in-law said lovingly.

After drinking, I sat down, Wanfang picked up the glass again, and said:

"Celebrate the victory of my big hero! Let's have a drink too! ”

We finished our drinks laughing.

"Everyone drinks casually, and listens to Ah Liu's story about solving the case." The father-in-law reminded that it seemed that the father-in-law was becoming more and more interested in solving the case.

I nodded and said:

"There's a lot going on in a day today.

After going to work, in Director Zhang's office, there were Zhang Brigade and Teacher Liu to participate, and according to my personal intention, it was decided that my specific work would be in the technical team of the Criminal Investigation Brigade; Subsequently, a welcome meeting was held at the Criminal Investigation Brigade, which was personally presided over by Director Zhang, at which in addition to welcoming me, there was also an important announcement that I had been appointed as the deputy leader of the technical team. ”

"Haha, my son has been promoted, come on, let's have a double drink to celebrate! Cheers to my son's ascension! "My mother-in-law spoke first this time.

"Okay, this wine has to be drunk!" The father-in-law said loudly.

When everyone had finished drinking, I continued:

"The welcome meeting didn't last long, and then there was the case meeting, which was a series of temple robbery cases, and the team leader of the field team led people to start investigating in July, but there was no progress, Director Zhang had seen it for so long, and the case had not been solved, so he was a little unhappy, so he asked me to join this special class.

After the work was arranged, Director Zhang left, and several of our special class members continued to hold meetings.

I listened to it, and the surname of the case was very bad, not only robbery, but also binding and beating the victim, and the methods were very cruel; This case was against the temple again, and the masses were very dissatisfied and reported to the bureau, so it is normal for Director Zhang to be a little unhappy.

Subsequently, Captain Zheng of our technical team introduced the scene situation, and after their hard work, the footprints of the perpetrator were extracted at the scene, and there were fingerprints.

It should be said that the conditions for solving this case are very good. ”

"Yes, there are footprints and fingerprints, why can't you solve the case?" The father-in-law asked.

"Dad, although there are footprints and fingerprints, but you have to find out whose footprints and fingerprints are, right? This job of finding people is like looking for a needle in a haystack, which is very difficult. I explained.

"Yes, yes." The father-in-law nodded and said.

"But, now that my big hero is here, you're the best at overcoming what others think is difficult, and you must have figured out a way to find a needle out of the haystack." Wanfang said with a smile.

Everyone burst out laughing.

"Fang, you're really right this time." I nodded in reply.

"Haha, I'm right again, I'm going to have another drink with you!" Wanfang said happily and picked up her wine glass.

After a glass of wine, I continued:

"The reason why I was able to overcome what others thought was difficult was purely based on analysis.

First of all, the perpetrators all entered the room by pulling the window, and one of the windows in the three cases was made of very thick steel bar, which was so strong that ordinary people could not pull it, let alone pull it open. From this, I analyzed that the perpetrator was very energetic and did heavy physical work, and the peasant's surname was probably large, which was the characteristic of his identity.

Secondly, in the course of committing the crime, after entering the room, the perpetrator immediately tied up the victim, and the method of binding is quite special, a bit similar to the binding method of the armed police soldiers in our detention center, that is, the five flowers are tied, therefore, I analyze that this person may have been in prison, this is his previous information, historical situation.

Third, the places targeted by the perpetrators are relatively special, and they are all temples. This temple was originally a place for everyone to pray to God and worship Buddha, and ordinary people would not go there to rob it; Especially when he was committing the crime, he began to tie up people when he entered, and he felt familiar with the way, and his methods were very sophisticated, and the analysis believed that this person was likely to have robbed the temple before.

Fourth, when interviewing the victims, they all said that this person had a local accent and was in his forties, and the analysis believed that he was from his own county.

In this way, the situation came out, this is a person from this county who was once sentenced to a prison sentence of more than 40 years old for robbing a temple, and the scope has been reduced to a very small one, which is very easy to do, because the intelligence team of our criminal investigation brigade has the information of the sentenced person, not only photos, but also fingerprints. ”

"I know, I know, you're following the map again, identifying it, right?" Wanfang asked happily.

"You're right, but there's a quicker and easier way. Have you noticed, I just said that Captain Zheng of our technical team extracted the fingerprints of the perpetrators at the scene, and we only need to call out the fingerprints of these people, a pair.

After listening to my analysis, several people in the special class were very excited, and felt that the case was about to be solved, so they rushed to the office of the intelligence team together, and everyone worked together to retrieve information. His name is Dong Ruihai, male, born in 1954, from Dongjiawan, Taiping Village, Huapai Town, our county, and was sentenced from 1991 to 1996 for robbing a temple.

In the afternoon, we rushed to Huapai Town to arrest Dong Ruihai, who is currently under review. I originally wanted to stay and continue the review, but Director Zhang said that I should pay attention to rest, protect talents, and not let me participate in the review, so I came back. ”

"Listen to you, this case is really simple, this can be analyzed, there are ideas, and the work is simple!" The father-in-law sighed.

"Son, your leader cares about you so much, you must work hard and live up to the leader's care and love." Mother-in-law said.

"Mom, I will, I will work hard and repay the care and love of the leader with excellent results." I said seriously.

"That's right, son, let's have a drink." The mother-in-law said appreciatively.

After drinking, I said:

"Mom and Dad, I'm done eating, and I have to go to the bureau for a trip."

"What's wrong with you?" Wanfang asked.

"The unit assigned me a single dormitory, and a few people from the technical team helped me move things in, and I didn't have time to tidy it up, I wanted to finish eating and go and see. In addition, I have just joined the technical team, and I am not very familiar with forensic technology, so I have to hurry up and study hard. I replied.

"What's the matter, aren't you going to live at home? It's good at home, why don't you live at home?! Wan Fang asked with a blushing face, her tone full of eagerness.

"The single dormitory is just for me to rest temporarily, such a good home, why should I live there?!" I said with a smile.

"Tell me clearly, scare me." Wan Fang said angrily.

The father-in-law and mother-in-law laughed, and Wanfang's face turned even redder.

"What are you laughing at? Don't laugh! I'll go with Ah Liu, read with him, and then come back together. Ah Liu, let's eat quickly, and when we're done, I'll have to see your dormitory. Wanfang raised her head and said.

"Son, do you still need to bring groceries or other things from home?" The mother-in-law stopped laughing and asked.

"It's all here, if you need it, let's talk about it later." I replied.

The mother-in-law nodded, and the father-in-law took the cup again and said:

"Then let's have a reunion drink."

After the wine was drunk, everyone ate again.

Wanfang and I opened the door of room 209 on the second floor of the bachelor dormitory, and when we turned on the light, it was very small, with only a bed and a table.

Wanfang immediately started, made the bed, and arranged things neatly, very orderly.

After doing all this, the two of them came to my office again.

After pouring water for Wanfang, I said:

"Fang, you sit down first, just look at the book or something, I'll go to the first floor to see the review situation, and I'll come up immediately."

Wanfang nodded obediently.

Pushing open the door of the interrogation room, I walked in and found that the four heroes of criminal investigation, Ke Zunping, and Lu Jianjian, were examining inside.

Everyone nodded and did not speak.

I was about to sit down, but the leader of the conversation said:

"Crazy, a few of you are in charge of guarding, I have something to do with Captain Li and Team Leader Ke."

The madman nodded.

In the office of the talk team leader, everyone simply greeted each other and smoked cigarettes, and the talk team leader spoke first:

"Captain Li, didn't Director Zhang tell you to go back and rest? Why did you get here? ”

"I don't have anything to do in the evening, so I just go to the office to read the book and check the review by the way." I replied.

"The review is not very ideal, no matter how you ask, Dong Ruihai doesn't speak, it's like a dumb person, let's do it later!" The team leader said the plan.

"What are you waiting for, you can do it directly, let this old man see how powerful you are in criminal investigation! Know what a finger flick is! Team Leader Ke said with a smile.

"Director Zhang has reminded us many times that we should handle cases in a civilized manner, and in the afternoon he said that we would handle cases according to law. Said the team leader.

Everyone burst out laughing.

"Captain Li, do you have any good methods?" Team Leader Ke asked.

"You're very experienced in dealing with people with such ex-convicts." I shirked.

"Just tell me about it." The team leader said with a smile.

The two of them looked at me and nodded, looking like you must have a good solution.

"Blow him up!" I said with a smile.

"How do you fry it?" The talk team leader came to be interested.

"This kind of person who comes back from prison, ** laws and policies are useless, your mouth is dry and it doesn't work, it's you who work hard, what he values is evidence, and he will bow his head in front of evidence.

At present, we have three pieces of evidence in our hands: fingerprints, footprints, and identification photos. Then blow him up with one of these three pieces of evidence, the fingerprint identification certificate! Let him understand that under this kind of ironclad evidence, it is useless for him not to speak.

As soon as this iron-clad evidence comes out, your criminal investigator Sijie, Team Leader Ke, and Lu Jianshe will be angry again, not to mention that he is a farmer, no matter how cunning the fox is, he has to recruit him. I said with a smile.

"Team Leader, there is so much evidence, why don't you use it? What else are you going to do? Team Leader Ke said with a smile.

"Who's to say no, it's not like there's no time." Tan team leader smiled.

"Where are you torturing him, you are obviously torturing ourselves, finish the review early, and rest early." Team Leader's voice.

"Okay, let's take the fingerprint identification certificate and blow him up!" Talk about the voice of the team leader.

"I'm reading in the office, I wish you to blow up Dong Ruihai!" My voice.

After the plan, everyone left the office of the team leader with a smile.

Back in my office, Wanfang was reading a book, and I asked with a smile:

"Comrade Ke Wanfang, the book specialty of this technical team is very strong, can you understand it?"

"I read magazines, I don't read your professional books. This is the tea brewed for you, you watch and drink the tea, and when you finish drinking, I will refill the water for you. Wanfang said with a smile and brought me a steaming cup of tea.

"Okay, you read your magazine, I'll read my professional book." I took the tea and smiled.

I took out the book "Footprints" that I had learned in school and read it carefully. This is a very thick book, written by the China Criminal Police College, and the footprints are described in detail in the book.

According to the book, the first generation of the "Footprints" textbook came out in April 1984, which is the second generation of textbooks. Over the past 10 years, with the development of forensic science and technology at home and abroad and the changes in criminal methods, the theoretical system of footprint science has been continuously deepened and improved, and the technical methods have been continuously updated and improved.

Footprint refers to the general term of the traces formed by the contact between the surface of the scar-bearing object and the surface of the scar-bearing object such as the ground when the human body is barefoot or wearing shoes and socks during exercise, which is generally formed when wearing shoes, so it is commonly known as "shoe print".

Footprint science is an applied science, which studies the analysis of footprints on people's natural conditions and the identification of shoes, socks, and human bodies.

The object of the study of footprints is footprints, and the research of footprints has five aspects around the objects of footprint research and the specific application of footprints:

1. Research on the formation and change of footprints: mainly including the theoretical mechanism of footprint formation, the relationship between the interaction between footprint bearing objects and marking objects, and the influencing factors of footprints.

2. Research on footprint characteristics: Footprint characteristics are the basis of footprint research and the basis of footprint application, which is directly related to the scientific surname, legal surname, and success or failure of footprint application, mainly including the formation mechanism, surname quality, classification and quantitative research of footprint characteristics;

3. Research on footprint extraction and search: extracting high-quality footprints is the material basis for footprint application;

Fourth, the research on the application of footprints: including footprint analysis and footprint identification. The analysis mainly includes: the internal relationship between footprints and personal natural conditions, shoe types, occupations, walking postures and some cases, the mechanism of footprints changing with personal natural conditions, the quantification of analysis methods, and the sources of analysis conclusion errors; Footprint identification mainly includes: the identification of the structural characteristics of the footprint, the identification of the motion characteristics of the footprint, the comprehensive inspection of the footprint system, the comprehensive judgment of the difference point and the conformity point of the footprint characteristics and the quality analysis of the characteristics, as well as the quantification, standardization and automation of the footprint identification.

5. Research on the exchange and management of footprint information: it mainly includes the establishment of sample footprint archives and on-site footprint archives, which can also be divided into the archiving of barefoot footprints and the archiving of footwear footprints. They are the basis for the standardization and automation of footprint applications, and at the same time have direct significance for concatenation cases.
