Chapter 53 teaches and learns hand-in-hand, and improvises questions to test adaptation

There was nothing to say all the way, and after we went home, Director Zhang said that it was too hard for everyone to go out this time, and they had a two-day holiday and had a good rest at home.

I heard that I had two days off, Wanfang specially asked for leave and accompanied me back to my hometown in the countryside, my parents and sister were very happy, especially my mother praised Wanfang after understanding the situation, saying that this daughter-in-law likes home more than her son.

As soon as I got home, Wanfang threw me away, and I was glued to my mother every day, both in and out, and the relationship between the two was very good.

I'm also happy to relax, rest well at home, and get enough sleep.

After returning to the county, Captain Zheng and I cleaned up and summarized the on-site investigation work some time ago, and decided to further strengthen the on-site investigation work. During the site survey, we focus on improving the individual level and competence of each technician.

On this day, a house was burgled on Shengli Street in the county seat, and a report was received early in the morning. I took Xiao Ke and Xiao Cao to the scene.

"Xiao Ke, Xiao Cao, I will do a complete demonstration today, you will work according to this demonstration in the future, you must comprehensively, objectively, meticulously, and seriously investigate the scene, do a good job of on-site investigation records, one of the key points in our investigation is to extract trace evidence, especially fingerprints as the top priority."

The two nodded hurriedly.

When I went up to the victim's house on the second floor, Xiao Lu from the police station was making materials inside, and when he saw us coming, he immediately stood up and said hello:

"Captain Li, have you come to the scene in person?"

"What does it mean to come to the scene in person? The scene of this big and small case, I have time to see. I replied with a smile.

When the victim heard that I was Captain Li, she immediately stood up and shared her cigarettes.

I took the victim and Xiao Lu and the others to the opposite door and sat down.

The first is the on-site visit.

I took out the on-site investigation record paper and wrote:

"Your basic situation."

The victim replied:

"My name is Hu Pingkai, male, 28 years old, living in Room 501, Unit 2, Building 3, Nanwan Community, Jintiao Lane, Shengli Street."

I then asked:

"Tell me what you found."

Hu Pingkai went on to say:

"When I woke up at half past seven this morning, I found that the door was open. I just felt weird. I was the only one at home last night, my parents were out, why was this door open? I was shocked, it must have been stolen, right? I was busy going to the rooms. It was really stolen. Except for this room where I slept. The other two rooms have flips. I called the police. Then, the comrades from your police station came over. ”

"When did you go to sleep?" I then asked.

"I slept at two o'clock in the morning today, and I didn't sleep until after two o'clock when I played games." Hu Pingkai replied.

It seems that the time of the incident was between 2 and 7:30 in the morning. I put an emphasis on the notebook.

"What items were stolen?" I asked.

"There's cash, there's jewelry." Hu Pingkai replied.

I asked:

"Tell me more about the stolen items."

Hu Pingkai nodded and continued:

"In the master bedroom where my parents lived, there were two thousand dollars in cash in the closet, all of which were one hundred dollars; In their bedside table, my mother's pair of gold earrings and a gold ring were stolen, and my mother said that they were worth 1,800 yuan and 2,600 yuan respectively. ”

"Are there any characteristics of earrings and rings?" I asked, and I'm more focused on those.

"The earrings and rings are all gold, the earrings are the kind of leaves, and the ring is square on the top and there is a phoenix engraved on it." Hu Pingkai replied.

I put emphasis on the words leafy, square, and phoenix.

"Are there any other items besides these items being stolen?" I continued.

Hu Pingkai shook his head.

"Did you find out where the perpetrator came from?" My voice.

"I watched it for a long time, and I don't know where it came from." Hu Pingkai's voice.

"Have there been any thefts in your neighborhood recently?" I asked.

"Yes, a few days ago, Cao Xiaobo's house in room 302 of unit 3 was burglarized, but his house did not steal anything, so he did not report the crime, but people in our community knew that his house was burglarized." Hu Pingkai replied.

I nodded, and continued to write on the survey paper.

After the on-site visit, I began to take Xiao Ke and Xiao Cao to investigate the scene.

I glanced at it, and it was a three-bedroom suite with kitchen and bathroom. On the east side, that is, where we stand, is the living room, on the southeast side and adjacent to the stairwell is the master bedroom, in the southwest corner is the second bedroom, which is Hu Pingkai's bedroom, in the northeast corner is the study, and to the north of the living room is the kitchen and bathroom. The whole structure is relatively simple.

After putting on gloves, foot covers, and head coverings, I took out a strong light flashlight, turned off the lights in the living room, squatted down, turned on the flashlight, and the strong light immediately projected onto the ground.

"Xiao Lu, who of you just entered the scene?" I asked.

"I and three members of the joint defense team came in to check on the theft." Xiao Lu replied.

"Show me the shoes of the three of you." I said.

Xiao Lu and the three members of the joint defense team immediately took off their shoes for me, and I flipped them over and looked at the pattern on the soles.

Soon, I found these four shoe prints from the messy shoe prints, "one, two, three, four", I compared, counted the footprints on the ground, and then I returned the shoes to Xiao Lu and the others, Xiao Lu put on the shoes and stood there with a red face.

"Hu Pingkai, what shoes have you been wearing from last night until now?" I switched the person I was talking to.

"As far as the slippers on my feet are concerned, I wear them when I get home." Hu Pingkai replied.

"Take it off and show me." I said.

Soon, I also found Hu Pingkai's slipper prints on the ground.

"Did anyone else come in after you found out about the theft?" I asked.

"No more. No one else came in again. Hu Pingkai replied.

I was on the living room floor, marking a few footprints with chalk, and then I went to the master bedroom.

After the light was swept away, I found that there was a clear blocky pattern on the floor of the master bedroom, which was the same type of shoe print I marked in the living room, and this blocky pattern of shoe prints reacted in front of the bedside table and the wardrobe, and more importantly, from the direction of the toes of the footprints, they all pointed to the living room.

Could the perpetrator have been hiding in the room first? With doubts, I walked to the window. The windows are closed. There is no anti-theft net installed outside. I touched the window lightly, and the sash opened, and on the windowsill I found the blocky pattern of the fragments. I put my head out. Found the windows very close to the stairwell. You can reach it out as soon as you stretch it out.

I nodded slightly. came out of the master bedroom to the door of Hu Pingkai's room, squatted down again, and swept it with the light. There are only footprints of Hu Pingkai's slippers in the room.

When I arrived at the door of the study, in the strong light, I noticed another kind of circle-shaped shoe print on the floor, which also appeared on the floor of the living room.

On the floor of the corridor leading to the kitchen and bathroom, no footprints of these two types were found.

After reading and marking, I asked Xiao Ke and Xiao Cao to start taking pictures of the footprints, with Xiao Ke as the main one, Xiao Cao cooperating with the lighting, and I observed from the side.

When I had done all the footprints, I said:

"Xiao Ke, Xiao Cao, if the flashlight suddenly runs out of power, how do you shoot footprints?

The two didn't expect me to ask this question suddenly, and they looked at each other.

"See if the victim has a flashlight or a secondary light source in the victim's home." Xiao Ke thought for a moment before replying.

"With a flash, okay?" Cao replied.

I shook my head and said:

"Flash has a very large flare, which is definitely not a good idea. In this case, you can follow what Xiao Ke said, and find the victim to borrow a light source. Also, a good way to do this is to turn up the sensitivity. ”

"This method is good, why didn't I think of this, just turn up the sensitivity. Captain Li, you're better than me, a professional photographer! Xiao Ke exclaimed excitedly.

"What if you forgot to bring the scale?" I raised a new question.

"Then we have to shoot without scale, which we sometimes do." Cao replied.

"Or borrow, borrow his ruler." Xiao Ke said with a smile.

"You know what if the victim doesn't have these things at home?" I said with disgust.

Xiao Ke touched his head and said with a smile:

"Then it's like what Xiao Cao said, so I have to use the scale."

I shook my head and continued:

"There will be a lot of unexpected things to face when you watch the scene, and you must think more about how to think about it. In this case, we still have many ways to take fixed items instead, such as cash on our bodies, shoes on our feet, cash and shoes, we can measure the exact length after we go back, and then through this length, we can calculate the length of the footprint. This is an ad hoc contingency method with no method.

The reason why I came up with these two questions today is because, I see that when you came out of the team, you came out with survey tools, and you did not check the equipment and tools at all before you set off, which means that you fought a battle for which you were not prepared. I hope you will pay attention in the future. ”

The two nodded earnestly.

"Okay, the ground is finished, Xiao Ke, you will quickly take pictures of the scene." I said.

Xiao Ke's photography level is not bad, there are opposite photos, key photos, overview photos, and detailed photos.

Subsequently, we carried out fingerprint processing on each item that the perpetrator turned over and changed, and after the fingerprint was processed, Xiao Ke and Xiao Cao cooperated to take pictures first, and then extracted them with special scotch tape.

Xiao Ke picked up the survey record paper and prepared to draw a sketch of the scene.

I said:

"Xiao Ke, this kind of very simple scene map, do you want to draw it on the spot?"

"Yes, Captain Li, we usually draw sketches on the spot, and then draw the official scene map on the computer when we go back." Ke replied.

"You must cultivate your own memory, an excellent technician, after he has surveyed the scene, he must have a bottom of the overall situation and the key situation of the scene, and must keep it firmly in mind. I suggest that you go back and draw a picture of the scene directly on the computer, and if you can't remember the place, you can look at the photos and combine the paintings. I said.

Xiao Ke nodded and packed his things.
