National Forensic Doctor

"Go get some luminol."

Jiang Yuan turned around and gave an order, and asked someone to take pictures of the bathroom. Then three people squeezed into the small bathroom, divided an area into each, and started checking.

Jiang Yuan only bent down to check the wash basin and floor drain, then found a few corners and scanned them before exiting. Immediately afterwards, another on-the-spot survey from the Changyang Bureau came in.

When he was a novice, he was working on a case and did a second inspection of the bathroom. He and Wang Zhong spent several hours wiping it with cotton swabs.

Now, he entered the scene with a Coast survey. The suspect's living area was not enough for everyone to take charge of alone. There was no reason for one person to have a bathroom, and everyone had to compete for the job.

Compared with the case in Jiang Yuan's novice stage, everyone is a murderer and a suspect, but the suspects in the novice stage have more bathrooms.

Even the suspect this time could only rent such a small room. In any smaller room, the body would not be able to be moved, so how could the body be dismembered.

It can be said that this room is an economical and practical mortuary. A smaller house, or a house shared with others,

There is no way to dismember the body.

In today's cities with intensive surveillance, if a person, especially a man, cannot afford to live in a house with a separate bathroom, he is not qualified to dismember the body. Furthermore, he is not qualified to premeditate murder!

"Captain Jiang, we found a woven bag of the same style." The technician who was searching in the bedroom took out the woven bag contained in the woven bag from under the bed.

"Is this the coated one?" Jiang Yuan recognized it at a glance.

"Yes. Judging from the total number, there should be about 200 left. They are probably from the same batch as the woven bags used to dump the bodies. You can take them back and test them." The technician said.

"Have you found woven bags from other manufacturers?" Jiang Yuan asked.

The technician shook his head: "No, only this one."

Mu Zhiyang said from the sidelines: "The truck that the suspect drove was his own to move freight. Logically speaking, if you buy so much at one time, there is no need to buy from two or three manufacturers."

"That makes sense." Jiang Yuan agreed. This was a reasoning that only 001 Liu could make. It is estimated that the other two woven bags were obtained by the suspect from the victim.

Dumping the corpse twice means transporting the corpse twice, and the woven bag used for transporting the corpse for the first time cannot simply be thrown away. Regardless of whether the body was dismembered when the body was dumped for the first time - a fact that many friends who have never killed anyone don't know is that in addition to blood, the human body actually contains various other liquids and semi-liquids. As the muscles lose their activity, Finally, it can all flow out.

Therefore, the word "feces and urine" can be said to be a powerful description of the human body's loss of physical control.

"Has the suspect given an explanation?" Jiang Yuan asked smoothly.

Some suspects will think about it after they calm down in a police car for a while.

Wang Chuanxing came over and said: "I just followed up and the suspect kept silent. However, Brigade Cao has already led technical investigators to the community where the suspected first scene was. The suspect's mobile phone stopped in the community a few months ago. Almost 8 hours. In addition, a group of people passed by the warehouse area of ​​the clothing wholesale market. "

"Okay." Jiang Yuan nodded, with a relaxed expression on his face.

Although there is no conclusive direct evidence yet, there is enough information compiled from various aspects. Now let's see which side can hit it.

Soon, the technician came to report again: "Team Jiang, we are ready to spray luminol."

This thing is best viewed under a dark light, so what the technician actually means is that I want to lock everyone in a dark room.

Jiang Yuan agreed.

People on both sides began to spray luminol and then drew the curtains.

Today's police generally do not use luminol. After all, it requires a ready-made solution. Although there is a ready-made "pure" of luminol, it still needs to be mixed with sodium carbonate and hydrogen peroxide. Moreover, since it is a configuration, you have to be a little more particular about it. When you prepare measuring cylinders, measuring bottles, etc., you can easily get a box of them.

In comparison, technicians doing on-site inspections now prefer to directly use multi-segment light sources, which is what Huang Qiangmin configured for various inspection lights not long after he made money. Different wavebands can be adjusted, and different body fluids or liquids will glow under light sources in different wavebands.

For example, semen emits orange fluorescence when exposed to visible light with a wavelength of 430 to 470 nanometers.

These all belong to the principle of cold luminescence, just like the fluorescent sticks shaken during concerts.

However, the use of multi-segment light sources for surveying has certain requirements on the number of targets and relatively high timeliness requirements.

To put it simply, like semen, if too little is ejaculated or too early, it may be missed.

Luminol is different. You can see the bodily fluids from a few years ago. One drop is enough.

The bathroom is dark, with no blue light coming out at all, which shows that the bathroom decoration has played a certain role.

But surprisingly, not surprisingly, a glimmer of light emitted from the kitchen.

"There should be blood or something on the ground." The two technicians were talking while taking pictures.

"It feels like a piece of pork belly fell to the ground." Mu Zhiyang also came over to take a look, with a chatting smile like a social worker's daily work.

"It does look a bit like it." Jiang Yuan walked over, took a look, made some gestures, and said, "Maybe it was when the murderer was cutting up the body.

It was difficult to operate in the bathroom. When I took some parts with higher fat content for operation, the meat fell to the floor. Because fat is applied to the blade, the knife will become dull. "

The forensic doctor who came with him also said: "It's possible. Maybe the fat fell to the ground like this. There is no blood. The murderer may not have cleaned it up properly. Maybe he forgot?"

Mu Zhiyang's social animal-like daily work chat and smile have long since stopped and he only uses the ordinary non-forensic social animal's daily thinking.

He said: "Maybe I feel that there is flesh and blood in the kitchen, so there is no need to cover it up."

"Just take a DNA test." The forensic doctor who came with him said and squatted down to take samples.

Jiang Yuan watched the whole process with his hands tied. It seems that his level of field survey is already very high, but one thing is that this site really does not need such a high-level field survey.

A group of people hurriedly completed the sampling, then returned to the bathroom, checked the sampling situation, and waved, "Let's dig out the decoration."

The technicians in the bathroom exited one after another, and saw Shen Yaowei entering with a sledgehammer, followed by three people holding cameras to film him.

Boom.

stay.

Boom.

stay:

There are people who shoot videos, people who take pictures, and there are observers who poke their heads outside the door.

"Work hard!"

"Come on!"

"Brother, Captain Jiang is waiting for lunch."

Wearing white coats, plastic hoods, and rubber gloves, everyone enthusiastically cheered for Shen Yaowei, who was holding a sledgehammer.

The space in the bathroom is limited, so I can only help my brother in this way.

"Wipe the sweat." Shen Yaowei stretched out his head. He held the hammer with both hands, but he didn't want the sweat to drip to the ground. He would spray luminol again later.

The detectives selected the ugliest one and went over to Shen Yaowei to wipe his forehead with tissue.

"Get the chisel on."

When a tile is broken, someone comes over to help and carefully starts to lift up the cement layer below.

Shen Yaowei mustered up all his strength and continued to fuck hard.

Finally, under a large layer of tiles and cement, part of the old decoration was exposed.

It can be seen that the suspect once wanted to destroy all the decorations and install new ones, but he obviously underestimated the workload of the project, so only part of the old decorations were damaged, and the final decorations were made after Renovation was done on the damaged decoration.

Even so, one month would probably keep Xin Shengsi busy.

Seeing this, Jiang Yuan said without waiting for everything to be smashed: "Spray some Luminol and see."

Shen Yaowei quickly exited.

The technician took a small spray bottle and sprayed it once. Then he turned off the lights and drew the curtains, and saw that dots of blue light had appeared.

"Haha, sure enough, they are all down there."

The police officers present became happy.

The recognition rate of luminol is one in a million. For things like blood stains, no matter how clean they are, it is useless. Even with many chemical reagents, it may not be able to cover them perfectly. The suspect's new decoration was actually a smart move, but in this case, it was to help preserve evidence.

Jiang Yuan immediately ordered people to take samples.

Shen Yaowei took advantage of his rest time to quietly send a message to his cousin: [Captain Jiang gave me credit again today, I’m sorry. 】

【What's going on? ] Shen Yaoguo, the leader of the Changyang City Public Security Detachment, responded to the message instantly.

Shen Yaowei explained what he had just done, and then said: "I don't know, I thought I gave him such a big gift. He took great care of me." 】

[Don’t say it, it’s true. Let me think about it ---"-" Shen Yaoguo's WeChat message flashed, and after a while, he entered the content again: [Jiang Yuan seems to be not satisfied with the security environment in front of their Jiangcun community, and he has made a special report before. 】

Shen Yaowei's eyes lit up: [Yes, yes, Captain Jiang was quite concerned about this before - Captain Liu also specially handled a few cases over there, to shock him. Could it be that he looked down upon me just for this reason? 】

Shen Yaoguo: [Don’t think so wildly. definitely is! You entered the city bureau with the name of Mr. Yao, what are you pretending to do now? 】

Shen Yaowei smiled self-consciously: [That's right, it can't be because of my shooting skills. 】

Shen Yaoguo: [So, I asked you to learn skills, and you went to practice shooting. No more talking, I will seize the time to make preparations. Recently, the incidence of criminal cases in various counties has decreased, which has highlighted public security problems. 】

Shen Yaowei: [What are you going to do? 】

Shen Yaoguo: [Public security improvement activities, ready-made templates, are specifically targeted at these urban-rural fringes. Jiangcun community was originally a low-security area in Ningtai County. I took a brigade to help and gave them a good plow. It would be best if he could plow to the bottom and clear out all the mud at the bottom. Those who fight or race in the early hours of the morning give shit! 】
