teach me how not to be the police

Chapter 53 Teaching and Learning Hands-On

There was nothing to say all the way, and when we got home, Director Zhang said that everyone had been working too hard on this trip, so we had two days off and had a good rest at home.

I heard that I had two days off, Wanfang 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 she understood the situation, saying that the daughter-in-law here is better than her son. like home.

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

I am also happy and relaxed, resting well at home and getting enough sleep.

After returning to the county seat, 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. Even for ordinary cases, Captain Zheng and I also took turns to lead teams to investigate.During the on-site survey, we pay great attention to improving the personal level and ability of each technician.

On this day, a house was burglarized 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, and you will work according to this demonstration in the future. You must survey the site comprehensively, objectively, meticulously, and earnestly, and keep records of the site survey. One of the key points in our survey is The extraction of physical evidence, especially fingerprints, is the most important thing."

The two nodded hurriedly.

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

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

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

When the victim heard that I was Captain Li, he immediately stood up to share the cigarettes.

I took the victim, Xiao Lu and others to a family opposite, and sat down.

The first is the site visit.

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

"Your basic situation."

The victim replied:

"My name is **kai, male, 28 years old, and I live in Room 3, Unit 501, Building [-], Nanwan Community, Jintiao Lane, Shengli Street."

I then asked:

"Tell me about your discovery."

**Kay continued:

"At 07:30 this morning, when I woke up, I found that the door of my house was open. I felt strange. I was the only one at home last night, and my parents were out. Why is the door open? Surprised, it must have been stolen? I hurriedly went to various rooms to have a look. It was indeed stolen. Except for the room where I slept. The other two rooms were flipped. I called the police. Afterwards, your police station Comrades are here."

"When did you go to bed?" I asked.

"I went to bed at two o'clock in the morning today, and I didn't go to bed until two o'clock after playing games." **Kai replied.

It seems that the incident occurred between 2:7 am and [-]:[-] am.I typed a key number in the notebook.

"What items were stolen?" I asked.

"There is cash and there is jewelry." **Kay replied.

I asked further:

"Tell me specifically about the stolen items."

**Kay nodded and continued:

"There was 2000 yuan in cash in the wardrobe in the master bedroom where my parents lived, all of which were in 1800 denominations; in their bedside cabinet, my mother's pair of gold earrings and a gold ring were stolen. My mother Having said that, their value is 2600 yuan and [-] yuan respectively."

"Are there any characteristics of earrings and rings?" I asked, and I paid more attention to these.

"The earrings and the ring are both gold. The earrings are leaf-shaped. The ring is square with a phoenix engraved inside." **Kai replied.

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

"In addition to these items being stolen, were there other items?" I continued.

**Kay shook her head.

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

"I watched it for a long time, but I don't know where it came from." **Kai's voice.

"Is there anything stolen in your community recently?" I asked.

"Yes, a few days ago, Cao Xiaobo's house was burglarized in Room 3, Unit 302, but nothing was stolen from his house, so there was no report, but everyone in our community knows that his house was burglarized."** Kay answered.

I nodded and continued to record on the survey record paper.

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

I glanced at it, and it was a suite with three bedrooms, one living room, kitchen and bathroom.The east side, where we are standing, is the living room, the southeast side is adjacent to the stairwell is the master bedroom, the southwest corner is the second bedroom, which is **Kai’s bedroom, the northeast corner is the study, and the north of the living room is the kitchen and bathroom.The whole structure is relatively simple.

After putting on the gloves, foot covers, and headgear, I took out the strong flashlight, turned off the light in the living room, squatted down, and turned on the flashlight. The strong light immediately projected onto the ground. Less messy footprints.

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

"The three defensemen and I came in to check the theft." Xiao Lu replied.

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

Xiao Lu and the three defenders immediately took off their shoes for me. I flipped the shoes over and looked at the pattern on the soles.

Soon, I found these four kinds of shoe prints from the messy shoe prints, "one, two, three, four", I compared them, counted the footprints on the ground, and then returned the shoes to Xiao Lu Waiting for someone, Xiao Lu put on his shoes and stood there with a flushed face.

"**Kay, what shoes have you been wearing since last night?" I changed my conversation partner.

"As for the slippers on my feet, I always wear them when I go home." **Kai replied.

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

Soon, I also found **Kay's slippers on the ground.

"Did anyone else come in after you found out it was stolen?" I asked.

"No more. No one else came in." **Kay replied.

After I marked a few footprints with chalk on the living room floor, I went to the master bedroom.

After sweeping the light, I found a clear block pattern shoe print on the floor of the master bedroom, which is the same type as the one I marked in the living room, and this block pattern shoe print is on the bedside table, dressing closet There are responses from the front, and more importantly, from the direction of the toes of the footprints, they all point to the living room.

Might the perpetrator hide 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 window sash opened in response, and on the window sill, I found the blocky patterns of remnants.I poked my head out.Found the window very close to the stairwell.You can touch it as soon as you stretch out your hand.

I nodded slightly.After coming out of the master bedroom to the door of ** Kai's room, he squatted down again and swept it with the light.Only the footprints of **Kay's slippers were left in the room.

When I arrived at the door of the study, under the strong light, I found another kind of circular shoe print on the ground, which also appeared on the living room floor.

These two kinds of footprints were not found on the ground of the aisle leading to the kitchen and bathroom.

After reading and marking, I asked Xiao Ke and Xiao Cao to start taking pictures of the footprints, mainly Xiao Ke, Xiao Cao cooperated with lighting, and I observed from the side.

After all the footprints were taken, I said:

"Xiao Ke, Xiao Cao, if the flashlight suddenly runs out, how can you take pictures of footprints?

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

"See if the victim has a torch or an auxiliary light source at home." Xiao Ke thought for a while before answering.

"Use a flash, okay?" Xiao Cao replied.

I shook my head and said:

"The flash has a very large light spot, which is definitely not acceptable. In this case, as Xiao Ke said, you can ask the victim to borrow the light source. In addition, a good way is to increase the sensitivity."

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

"What if you forget to bring the scale?" I asked a new question.

"Then we have no choice but to use the scale, which is what we do sometimes." Xiao Cao replied.

"It's better to borrow, borrow his ruler." Xiao Ke said with a smile.

"You know what to borrow, what if the victim doesn't have these things at home?" I scolded.

Xiao Ke touched his head, smiled and said:

"Then it's just like what Xiao Cao said, I have no choice but to use the scale."

I shook my head and continued:

"Looking at the scene, you will face many unexpected things. You must think more and think of ways. In this case, we still have many ways. We can replace them with fixed items, such as the cash on our body, our We can measure the exact length of the shoes, cash and shoes on our feet when we go back, and then calculate the length of the footprint through this length. This is a temporary contingency method that has no method.

The reason why I asked these two questions today is because I see that when you came out of the team, you came out with survey tools, and you basically didn’t check the equipment and tools before you set off. An unprepared battle.I hope you will pay attention in the future. "

The two nodded seriously.

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

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

Afterwards, we fingerprinted every item that the perpetrator turned over and changed. After the fingerprints were 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, do you want to draw this very simple on-site drawing?"

"That's right, Captain Li, we usually draw sketches on the spot, and then draw the official scene on the computer when we go back." Xiao Ke replied.

"You must cultivate your own memory. An excellent technician must have a solid understanding of the overall situation and key situations of the scene after he has inspected the scene. Draw a picture of the scene, and if you can't remember the place, you can look at the photo and combine it with the painting." I said.

Xiao Ke nodded and packed up his things.
