The old things I repaired have become fine

Chapter 115: Micro-research on the mystery of death (asking for a guaranteed monthly ticket) (asking for subscription)
The memory that Shen Le was involved in was much brighter than the previous one and the one before that.

Yingying has grown up a lot, from a crying little girl of seven or eight years old to a tall and fit girl of seventeen or eighteen years old.

She had her hair cut short, with her entire ears exposed, and she was sweating profusely on the playground: running, jumping, climbing over the wooden wall, and jumping into the sand pit.

They practiced grappling and fighting, practicing the movements of capturing prisoners, and punching again and again, with great vigor.

After the classes on the playground were over, she would go to the library and study hard. Law, psychology, fingerprints, forensic medicine, statistics...

There were books piled up high and thick, one after another, some in simplified Chinese horizontally, some in traditional Chinese vertically, some in English, some in Russian, and some in some other language.

Shen Le felt dizzy just by looking at those words. She frowned and flipped through a dictionary thicker than her fist, reading it word by word and book by book.

She changed the notebooks one after another, and in each one there were long notes, excerpts, and drawings.

In three years, the girl grew from a freshman to a brave police officer. However, when it came time for graduation assignment, she ran into trouble:
"I'm going to the criminal police team! I want to fight criminals!"

Yingying stood in front of the teacher in charge of the assignment, her body trembling slightly, her tanned face flushed with anger:

"I enrolled in our school just to become a criminal police officer! If I were a police officer, I... I..."

After she said a few words, tears welled up in her eyes. If she was a police officer, if she could have become a police officer a long time ago, would her brother not have died?

If the brother who loved her, made all kinds of dolls for her and created that beautiful dollhouse was still alive, would she have a beautiful sister-in-law and a lovely little nephew?
The teacher was in a dilemma. This little girl was a family member of a martyr, and she was the only descendant of the family after her three older brothers died.

Children like this always need care. How can they be assigned to the most difficult and dangerous criminal police position?

"Student Chen Haiying." She tried to speak calmly and rationally:

"There is no distinction between high and low jobs. Any job is to serve the people. The people's police should obey the orders of the organization and go to where the party and the country need them..."

"Isn't being a criminal police officer meant serving the people?" Yingying was still trying to argue:
"Don't we need female detectives? I heard a few days ago that there are very few female detectives at the grassroots level. Why can't I be allowed to go down?!"

"Student Chen Haiying, you are an outstanding talent cultivated by our school, and your abilities in many aspects are very rare." The teacher continued earnestly:

"Many people can be female police officers or female criminal police officers, but your position cannot be replaced by just anyone."

"But teacher..."

"Student Chen Haiying, obey orders and follow instructions!"

"……Yes!"

Yingying stayed at the school and became a teaching staff member. However, the little girl soon encountered new troubles:
"...Why don't you understand?" Yingying's assistant teacher, Mr. Li, who teaches Criminal Investigation, was so angry that his forehead was blazing with anger:

“The deceased was found by his family sitting on the ground in front of a chair in the living room, with a head injury and bleeding, and there was a lot of blood on the ground.

There were no abnormal phenomena of damage, overturning or falling over of items in the living room. Two small bloodstains were found on the south wall 0.85 meters above the backrest, from bottom to top..."

He talked nonstop, recounting all the details he had discovered in the case:
"...In this case, do you think it was suicide or homicide? Why?"

Yingying sat in the last row of the classroom, listening attentively. She felt that Teacher Li had explained it very clearly, clearly, and thoroughly.

However, these police officers who were assigned to the short-term training for two months all looked confused:
"I can't think of it! Teacher, you said so much, we can't remember it all!"

Yingying felt embarrassed for Teacher Li. But Teacher Li was still very patient:

"Okay, let me say it again." She began to draw the floor plan of the house on the blackboard, explaining as she drew.

Where is the window, where is the table, where is the chair; in which direction did the person fall, where was the bloodstain found;
There was incense ash from the windowsill to the chair next to it, and on the ground between the table and the chair, there were overlapping footprints of people wearing socks, some of them coming in, and some of them going out...

"now what?"

In a classroom, there are more than 20 police officers. Five or six of them seem to be deep in thought, while the remaining dozen or so still look confused when facing the big and small squares, big and small circles on the blackboard.

In particular, the height and direction of the bloodstains, this kind of three-dimensional information, the picture Yingying drew on the blackboard had no way of presenting it...

She stumbled through the class. After class, she chatted with Teacher Li, and the middle-aged police officer laughed at her:
"It's okay. These police officers are all over 40 years old. Most of them have only primary school education, and junior high school education is considered high. If you explain it on paper, it's really hard for people to understand!"

"What should we do then? If we encounter a case, should we bring the students directly to the scene?"

"That's not necessary. We have the written documents and the records. If that doesn't work, we can just draw a picture for them to see. If that doesn't work... if we can't solve the case, we still have our superiors!"

But Yingying refused to give up. If they couldn't understand what was said on paper, then she would give them examples! Yingying spent several days and nights in the library studying and immediately wrote a report:

Apply to build a simulation site!

Apply for an empty room or classroom, put temporarily unused furniture in it, and find someone to play the corpse.

Or you can make a dummy out of bamboo poles or straw and set up a fake scene for students to practice investigation!
The application was submitted and quickly approved. The teacher in charge of logistics was a little embarrassed, but still tried his best to provide her with the following conditions:
"Xiao Chen, you can borrow any tables, chairs, or anything else the school has. Just return them properly. And be frugal with red ink and other things!"

Furniture, simulated corpses, red paint pretending to be blood. Chen Haiying dragged everything here by herself, arranged everything carefully, and carefully reconstructed every aspect of the scene. The direction of blood splashing, falling, and flowing, the footprints at the scene, the marks on the furniture, the door, the window, the door lock...

The simulated survey was a great success!
The police officers who received the short-term training said:
"Teacher Chen, once you put it this way, we will understand! This is how we see it when we watch the scene!"

However, after the teaching was successful, Yingying soon discovered new problems. First, the workload was heavy. For each on-site investigation class, she had to spend at least three hours preparing in advance.
Second, there were too many materials consumed. Although the furniture and other things were all borrowed, the red paint, the newspapers sprayed with red paint, the clothes on the mannequins stained with red paint...

These are all consumables. When changing a case, a new set must be made. In that era of scarcity, these supplies put great pressure on the logistics teachers.

Third, the cases cannot be fixed. If you change the case, you have to rearrange it, and the scene of the original case will disappear.

If there is any way, just fix these scenes!

If you want to talk about a certain example, just take the students to that room and let them see it for themselves!
Although she thought so, Yingying knew that this was completely impossible. There were limited rooms in the school, and it was extremely difficult to make room for her.
Furniture and supplies are also limited, and it is even more impossible to fill every simulation case room with furniture and dummies.

After all this trouble, it seems that the most economical way is to make impromptu arrangements every time during class?

Yingying left work with a sad face. When she got home, her mother felt very distressed to see that she couldn't eat or sleep well and looked absent-minded:
"Yingying, work is work, and life has to go on. Seeing you like this, not only do I feel bad, your dad feels bad too, and your brother in heaven would feel bad too if he saw you like this!"

elder brother?

elder brother!

Yingying was stunned for a moment, then suddenly stood up, pushed aside the dishes and ran upstairs. In the bedroom, a tall and wide cupboard stood quietly by the wall, covered tightly with a blue cloth, so that nothing could be seen inside.

Yingying lifted the cloth, almost touching the glass door, to look at the furnishings inside:

Bed, sofa, table, chandelier, the man on the sofa, the woman on the bed.

A dressing table, a small table, a small chair, a doll in a beautiful little dress...

That's it!
That's it!

All I have to do is make a small house like this, put furniture and people in it, and then I can demonstrate it to the students!

I can put two of these small rooms on my desk! If that doesn't work, I can apply for another cabinet. If you want to talk about any case, just take out the small room!
"Mom, Mom!" She turned and shouted:

"Can you find someone to teach me carpentry?"

There was no carpenter, and the Chen family didn't have enough connections to find a ready-made carpenter to teach a layman like her from scratch.

However, when she reported her idea, Teacher Li, who taught criminal investigation, was very supportive and asked the logistics department for help. He introduced a person to her:

"Comrade Chen Haiying, let me introduce you, this is Master Li from the Logistics Department.

If there are any broken furniture, doors or windows in the school, you can go to him for repairs. If you have any ideas, you can tell him -"

The carpenter sawed, planed, and shaved wood, glued the wood pieces together into pieces of furniture, and nailed them into dolls.

Of course, it can't be as delicate as my brother's, and the mortise and tenon structure is out of the question, but once the glue is applied, it has a shape that can indicate that this is a table or a chair.

Yingying tried every possible way to find cases, draw blueprints, and find all kinds of small bits and pieces, and put them together to make the case diagram she wanted:

Use small wooden strips to hold extremely thin carbon strips to make the pencil that the doll holds;
Cut the shavings into small strips and stick them into a clay hearth to pretend they were firewood;
Find a variety of fabrics to make clothes for the doll. They should be flexible and thin, but certainly not transparent. They should be able to withstand wrinkles, not unravel easily, and not tear when wet;

The most difficult part is to wrap a little cotton on one end of a sewing needle and draw various bloodstains:
Blood splattered on the wall stickers, bloody handprints on the wall near the light switch, bloody footprints on the floor stickers...

Yingying felt that her craftsmanship had improved by leaps and bounds after making these things. Shen Le lay beside her and felt like he was going blind!

And these efforts are not without effect. Time flies, the older generation of teachers retire, and Yingying, as a new generation of teachers, takes up the teaching position.

Then, with these teaching tools, she became the most impressive teacher in the school:

During class, each time the model house was brought out, it was different from the last time. A group of students gathered around the model, observing, sketching, taking notes, and discussing:
“I felt like suicide.”

"No, no, no, I think it was murder. Look, the blood was sprayed behind the deceased, high up - if it was suicide, the blood couldn't have sprayed that place!"

"If it were me, I would pay extra attention to the outside of the house to see if there were any unusual footprints..."
