Chapter 085 One Bay Two Cases Investigated at the Same Time, and the Chief Investigator was temporarily appointed

When we came out of the hospital, we asked Xiaohu to lead the way and rushed directly to the scene of the crime.

By the time we arrived at the scene, field investigators had already started their investigative work.

When I found Team Leader Chen, I told him what I knew, and he immediately arranged for a madman to investigate.

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

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

There are 48 households and 159 people in Huang Mudan Bay, which is located in a relatively flat area, and there is only one east-west machine farming road in and out of the bay, and the west side of the road leads to Cheng Simao Bay in the same village; The east side extends to the East (Dongyang County) Copper (Copper Mining Town) Highway, and Chenggong Town and Tongkuang Town are divided by the East Copper Highway.

Standing on the East Copper Highway, looking back, the entire Huangmitan Bay is in full view. This is a small bay, and at a cursory glance, it looks like fifty or sixty households. The structure of the houses is dominated by old-fashioned low-rise houses, with occasional new two-storey buildings, which stand out as if they were standing out from the crowd.

If two cases occur at the same time in one night, who of the two will come first and who will come later? That's what I'm going to solve first.

Huang Yuying's house is located in the middle of the east side of Wanzi, while Huang Yungzhi's house is located on the west side of Wanzi. Judging from the investigation, Huang Yuying was discovered at five o'clock, and Huang Rongzhi was discovered at six o'clock. Combined with the analysis that there is only one machine farming road in and out of the bay. It is also in line with the above conclusions. It seems that the perpetrator went down from the East Copper Highway to the machine farming road and then entered Wanzi. After committing two crimes in a row, he should have returned to the Dongtong Highway from the original route to escape.

After determining the route of the perpetrators, we searched the machine farming road and the associated Dongtong Highway, and found no clues.

After reminding Xiao Ke and Xiao Cao to take photos of their directions, we returned to Huang Yuying's house and waited for the arrival of the city bureau detachment.

From the outside, Huang Yuying's house is a five-room house, sitting north and facing south, with houses on the east and west sides next to each other. And they are all small lanes of about 1.5 meters. The alleyway is sandwiched by two walls, and there are no doors and windows, so it is impossible to be an entrance and exit here. On the south side, there is a bare east-west passage. It's not like other people's homes, you always have to plant trees or something in front of the door as decorations or decorations. The north side is also separated by a passage. It is the home of other villagers. However, this house has planted a few gardenias, which is kind of a little bit of a decoration. To the outside of the house are the front and back doors on the north and south sides. Because the city bureau has not yet come, we are unable to survey these two gates. It can only continue to watch from afar.

I'm done with this door. Just look at the window.

On the south side, i.e. in the front, there are a total of four windows, centered on the hall and symmetrical on the left and right, which should be one window per room. The windows are small and medium-sized, with a horizontal log in the middle of each window, and then five vertical logs, which pass through the middle of the horizontal logs.

The logs and beams of the first, second, third, and fourth windows are all there, and it seems that it is impossible to enter through the south window.

On the north side, i.e. at the back, there are five windows, each of which is the same size, the same material, and the same intact as the front one, and it seems impossible to enter through these five windows.

Looking at the sky again, the whole house is divided by the middle of the north and south, the south is high and the north is low, and it is covered with green tiles, and there are no gaps or holes found in the tiles, and it seems that it is impossible to remove the tiles from the roof to enter the room.

The walls, windows, and roofs are not allowed to enter the room, and from the scene, all that remains is the door.

Now it's hard to get in, we have to wait for the city bureau to come before entering!

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

"Why haven't you come from this city bureau yet? It's been so long. Xiao Cao grumbled.

"This doesn't do anything, tell you to wait, you can't wait?" I asked with a smile.

"I'm in a hurry, I'm afraid that all the physical evidence inside will be destroyed." Xiao Cao touched his head and smiled.

"Okay, you will come to the scene today to investigate, and Xiao Ke and I will cooperate with you." I said.

"Captain Li Li Li, I'm not in a hurry, I'll wait, okay?" Xiao Cao said hurriedly.

Xiao Ke covered his mouth and smiled.

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

"Captain Li, this is a big case, this is a series of cases, I don't dare; If it's like a street theft, I can try it. Xiao Cao said.

I gently exhaled a puff of cigarette and said:

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

Secondly, it is also what you need to grow. You have to experience, feel, and gain experience in different crime scenes.

Besides, with me here, what are you afraid of? Be brave enough to accept the task, don't be like a little daughter-in-law! ”

Xiao Cao nodded heavily.

I went on to say:

"The scene of this case is not only investigated by you, but also reported by you, are you confident?"

"With Captain Li here, I have confidence." Xiao Cao puffed up his chest and said.

"What do you mean to have confidence when Captain Li is here?! Without me, you will investigate according to the regulations and procedures, and report according to the usual analysis, and you must also have confidence! I corrected.

Xiao Cao nodded busily again.

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

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

"What do you say?! Do you want to be the main survey? I asked rhetorically.

Xiao Ke stuck out his tongue and was silent.

Xiao Cao nodded and said:

"Captain Li, let me talk about it first, you can criticize and correct it where you can't get it.

1. Inspect the site and delineate the scope of inspection and inspection. We've just done it, and we've done it very well. They all went out on the highway. In this way, the combination of the peripheral site and the central site can completely avoid the mistake made by the previous technician who missed the masked hat in the toilet. This is a comprehensive site survey.

2. Determine the order of inquest and inspection. The principle to follow is to be static before moving, down first and then up, easy first and then difficult, first surface and then inside, first key and then general, first fixed and then extracted. In this way, it can ensure that the traces and physical evidence of the scene are not destroyed during the investigation, and the scene is protected to the greatest extent. This is what you usually remind us, a technician is going to investigate the site. Instead of going to sabotage the scene.

3. Preliminary inspection and inspection. Fixed site. This is a preliminary fixation of the scene, to ensure that the photography and video are in the original state, to avoid man-made damage. Taking pictures and videos, this kind of simple thing is done by Xiao Ke and me.

4. Detailed inquest and inspection. Finding, fixing and extracting traces, physical evidence. This is the focus of the site survey. I don't have a complete grasp of this piece yet. Leaders need to check the gates.

5. Record the on-site inspection and inspection, and improve the relevant procedures.

6. Inform the victim of the safety precautions to prevent the recurrence of similar cases.

Captain Lee. Do you see anything wrong? ”

I didn't answer, but looked at Ke.

Xiao Ke said with a smile:

"Brother Cao, you are too right. Learn from you! Hats off to you! ”

We all laughed.

"Xiaocao, there is one more question." I reminded.

"Yes, yes, yes, and the question of the witnesses, I'll go to the witnesses right away." After Xiao Cao finished speaking, he ran away, and soon, two witnesses from Tongwan came.

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

The criminal investigation detachment of the Municipal Bureau who came with Director Tang included the head of the Ai detachment, the Ke brigade of the technical brigade, and the police dog handler Xiao Yang, and everyone was busy greetings.

Captain Zheng also quickly rushed over.

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

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

"Ai detachment, then let's start the on-site investigation immediately?" Brigade Ke asked.

"You must be cautious and strive to extract useful trace evidence." Ai detachment admonished.

Several of us who are engaged in technology gathered together and briefly bumped into each other, Captain Zheng introduced our grouping, and the Ke team expressed his approval, and several people engaged in technology in the detachment were also grouped, tips and Xiaotang joined our group, and Captain Ke took the others to follow Captain Zheng.

I nodded to Xiao Cao, and he immediately said:

"Brother Fei, Brother Tang, let's make a simple division of labor, okay?"

Tip and soup looked at me a little surprised.

"Oh, I forgot to say, Captain Li asked me to investigate the scene of this case, this is the first time I have conducted an investigation at such a large scene, I hope you leaders will give me more advice." Xiao Cao explained.

The two of them smiled and nodded.

小曹 says:

"Captain Li and I went to the scene first, opened the passage, and then everyone went in. Brother Ke was in charge of taking pictures, I was in charge of video, and the two leaders of the city bureau were mainly guided. ”

Everyone nodded.

After putting on gloves, head coverings, and foot covers, Xiao Cao took a flashlight, and I followed behind and entered the room through the door.

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

The indoor floor is earthy, dry, uneven, and there are no footprints to be seen. However, Xiao Cao still scanned the ground with the light very seriously, inch by inch, and did not let go of any suspicious location.

After reading the hall, he went into the room on the west side, and after reading the room on the west side, he went to the room on the east side; Then to the back of the hall, then to the back room on the west side, then to the outermost room on the west side, then back to the small room at the back of the hall, then to the back room on the east side, and finally to the outermost room on the east side, a total of eight rooms of various sizes.

Although Xiao Cao was very serious and meticulous, no footprints or suspicious items were found on the ground.

After inspecting the ground, no useful traces and physical evidence were found, and I saw Xiao Cao's face sweating straight down, he must be nervous!

"Captain Li Li Li, what can I do about this, I can't see a single footprint on the ground?" Xiao Cao was really in a hurry.

"Do you think footprints can be extracted from such ground?" I asked.

Xiao Cao shook his head and said:

"The ground conditions are too poor to spot footprints."

"On-site investigation is not a subjective thing, it is an objective process, and it is normal and objective that footprints cannot be found on such a ground. You've done it very carefully. In the on-site investigation, traces and physical evidence are not only footprints, but also fingerprints and so on. Don't worry now, let's take it one step at a time. First of all, you have to calm down, if you can't calm down, it will affect the work behind, and then it will be a really failed on-site investigation. I said seriously.

Xiao Tang gave me a thumbs up.
