After leaving the hospital, we asked Xiao Hu to lead the way and rushed directly to the crime scene.

By the time we arrived at the scene, the field investigators had already started the investigation and visit.

After finding Team Leader Chen, I told him what I knew, and he immediately arranged for a crazy person to verify.

Captain Zheng made a simple division of labor. I was in charge of Huang Yuying's house site, and he was in charge of Huang Rongzhi's house site.

After the division of labor was completed, I took Xiao Ke and Xiao Cao to conduct a large-scale search and visit to Huangnitan Bay.

Huangnitan Bay has 48 households and 159 people. It is located in a relatively flat area. There is only one east-west road in and out of the bay. The west side of the road leads to Cheng Simao Bay in the same village; the east side extends to East (Dongyang County) Tong (Copper

The roads of Mine Town are divided into the boundary of Chenggong Town and Tongmiao Town with the Tongmiao Town East.

Standing on the Dongtong Highway, looking back, you can see the entire Huangnitan Bay. This is a small bay. At a rough look, it looks like fifty or sixty families. The house structure is mainly old-fashioned low-rise houses.

There may be several newly built two-story buildings in a while, which is particularly conspicuous.

One night, two companies had cases at the same time. Which one should come first and who will come first? This is the problem I need to solve first.

Huang Yuying's family is located in the middle of the east side of Wanzi, while Huang Rongzhi's family is located in the west side of Wanzi. According to the investigation, Huang Yuying was discovered at five o'clock, while Huang Rongzhi was discovered at six o'clock. Excluding other factors, only

According to time, the crime should be committed at Huang Yuying's house first, and then at Huang Rongzhi's house. Combined with the analysis that there is only one mechanized farming road entering and leaving Wanzi, it also meets the above conclusion. It seems that the perpetrator came down from Dongtong Highway to the mechanized farming road.

After committing two consecutive crimes, those who entered Wanzi should return to Dongtong Highway to escape from the original route.

After determining the route of the perpetrator, we searched the Mechanized Farm Road and the associated Dongtong Highway, but found no clues.

After reminding Xiao Ke and Xiao Cao to take the location photos, we returned to Huang Yuying's house and waited for the arrival of the Municipal Bureau Detachment.

From the outside, Huang Yuying's house is a house with five rooms facing north and south, with houses close to each other on the east and west sides. They are all small alleys about 1.5 meters. The alleys are sandwiched by two walls, and there are no doors and windows.

, It is impossible to be an import and export here. The south side is bare, which is just an east-west passage. Unlike other people's houses, trees must be planted in front of them as decoration or decoration. There is also a passage across the north side. It is the home of other villagers.

However, this house has planted a few gardenia trees, which are considered to be a bit of a decoration. The house is outside the two doors on the north and south sides. Because the city bureau has not come yet, we cannot investigate these two doors. We can only go far away.

Continue to watch.

After reading this door, just look at the window.

On the south side, that is, in front, there are four windows, centered on the main hall, symmetrical left and right, and should be a room and a window. The windows are small and medium-sized, with a horizontal log in the middle of each window, and five vertical ones.

The logs and vertical logs pass through the middle of the horizontal logs.

One, two, three, four, four windows with logs and horizontal trees are all there, and it seems that it is impossible to enter through the south window.

On the north side, that is, behind, there are five windows. Each window is the same size, the same material, and the same intact. It seems that it is impossible to enter these five windows.

Look at the sky. The entire house is divided by the middle position between north and south, high in the south, low in the north, and green tiles are covered with green tiles. No gaps or holes are found on the tiles. It seems that it is impossible to peel the tiles from the roof into the room.

This wall, window, and top cannot be entered. From the scene, the only thing left is the door.

Now it’s hard to get in, we have to wait until the city bureau comes before entering!

"Captain Li, smoke a cigarette." Xiao Ke said, handing over the cigarette.

"Why haven't the city bureau come yet? I've been waiting for so long." Xiao Cao complained.

"If you don't do anything, you're told to wait, but you can't wait?" I asked with a smile.

"I'm anxious, I'm afraid that all the physical evidence inside will be destroyed." Xiao Cao smiled, touching his head and touching his head.

"Okay, today you will be the main survey of this site. Xiao Ke and I will cooperate with you." I said.

"Captain Li Li Li, I'm not in a hurry, let's wait, can you?" Xiao Cao said hurriedly.

Xiao Ke covered his mouth and laughed.

"What's wrong? I don't have the confidence to investigate the scene of this case?" I asked.

"Captain Li, this is a major case, this is a series of cases, I dare not. If it is a theft case on the street, I can still try it." Xiao Cao said.

I let out a sip of cigarette lightly and said:

"Major cases should be investigated as general cases, and general cases should be investigated as major cases. For a technician, there is no distinction between general cases and major cases. The scene of each case must be carefully and meticulously investigated, and understand this

You are not afraid of the truth.

Secondly, this is also your need for growth. You must experience, experience and accumulate experience in different case sites.

Besides, with me here, what are you afraid of? Accept the task bravely and don’t be like a young wife!”

Xiao Cao nodded heavily.

I continued:

"You are not only responsible for the scene of this case, but also for reporting. Are you confident?"

"I have confidence with Captain Li here." Xiao Cao said with his chest straight.

"What does it mean to have confidence if Captain Li is there?! Without me, you should investigate according to regulations, procedures, and report according to daily analysis. You should also have confidence!" I corrected.

Xiao Cao nodded again.

"Tell me about your entire exploration plan." I said.

"Captain Li, are you really here?" Xiao Ke asked.

"What do you think?! Do you also want to take charge of the investigation?" I asked back.

Xiao Ke stretched out his tongue and stopped talking.

Xiao Cao nodded and said:

"Captain Li, let me talk first, you can criticize and correct me if you don't have any.

1. Inspection site, demarcate the inspection and inspection scope. We have done this work just now, and it has done very well. We have inspected it on the highway. In this way, the external site and the center site can completely avoid the previous technicians.

The mistake of missing out on the toilet was not found in the masked hat. This is a comprehensive on-site investigation.

2. Determine the inspection and inspection order. The principle followed is to be static first and then move, first down and then up, first easy and then difficult, first appear and then inside, first focus and then general, first fixed and then extract. Doing so can ensure that the investigation is

When not destroying the physical evidence on the scene, protect the scene to the greatest extent. This is what you usually remind us that a technician is going to investigate the scene instead of destroying the scene.

3. Preliminary inspection, inspection, and fix the site. This is the preliminary fixation of the site, ensuring that the photography and video recording are in its original state, and avoiding artificial damage. Take and video, such a simple thing will be done by Xiao Ke and I.

.

4. Detailed inspection, inspection, discovery, fixation and extraction of traces and physical evidence. This is the focus of the investigation site. I am not fully sure about this area. I need to check it out by the leader.

5. Record on-site inspections, check the situation, and improve relevant procedures.

6. Inform the victims of safety precautions to prevent similar cases from happening again.

Captain Li. Do you think there is anything wrong with it?"

I didn't answer, but looked at Xiao Ke.

Xiao Ke said with a smile:

"Brother Cao, you are so right. Learn from you! Salute to you!"

We all laughed.

"Xiao Cao, there is another problem." I reminded.

"Yes, yes, there are also questions about witnesses, I will go to find the witness immediately." After Xiao Cao said that, he ran away. Soon, two witnesses from Tongwan came over.

After smoking another cigarette, we finally saw Director Tang and others coming, and immediately stood up and met.

The Criminal Investigation Detachment of the Municipal Bureau who came with Director Tang were Captain Ai, Ke Brigade of the Technical Brigade, Xiao Yang, police dog trainer instructor, and others. Everyone was busy with greetings.

Captain Zheng also rushed over quickly.

"Captain Li, is there any source of smell?" Xiao Yang asked.

"We haven't entered the scene yet, waiting for you to come." I replied.

"Ai Detachment, then we will start the on-site investigation immediately?" asked Brigade Ke.

"You must be careful and strive to extract useful traces of evidence." Ai Detachment reminded.

Several people who were engaged in technology gathered together and simply met. Captain Zheng introduced our grouping. Team Ke expressed his approval and also grouped several people who were engaged in technology in the detachment, and Tie Fei and Xiao Tang joined us.

In the group, Captain Ke took the others to follow Captain Zheng.

I nodded to Xiao Cao, and he immediately said:

"Brother Fei, Brother Tom, can we make a simple division of labor, okay?"

Tie Fei and Xiao Tang looked at me, a little surprised.

"Oh, I forgot to say that Captain Li asked me to investigate the scene of this case. This is the first time I was investigating at such a large site. I hope all the leaders will give me some advice." Xiao Cao explained.

The two of them smiled and nodded.

Xiao Cao said:

"Captain Li and I went to the scene first, opened the passage, and then everyone went in again. Brother Ke was responsible for taking photos and I was responsible for recording videos. The two leaders of the municipal bureau focused on guidance."

Everyone nodded.

After wearing gloves, headbands and foot covers, Xiao Cao took the flashlight and I followed behind and entered the room through the gate.

As the light turned on, a bright beam of light slowly swept across the ground.
