Chapter 969 Peaceful Years

"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 area, 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 urban 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, Team 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 taking some parts with high fat content to operate, the meat fell to the ground. Because the fat was smeared on the blade, the knife would become blunt. "

The forensic doctor who came with him also said: "It's possible. Maybe the fat meat fell to the ground like this, and there was not much blood. The murderer might not have cleaned it up properly, or maybe he forgot?"

Mu Zhiyang's daily work and chatting smile, which was like a social animal, had long been restrained. He only used the daily thinking of ordinary non-forensic social animals.

Said: "Maybe he thought there was meat and blood in the kitchen, so there was no need to cover it up. "

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

Jiang Yuan watched with his hands tied throughout the whole process. Speaking of it, his on-site investigation level was already very high, but to be honest, this scene really didn't need such a high-level on-site investigation.

A group of people completed the sampling in a busy manner, and then returned to the bathroom, checked the sampling situation, and waved his hand and said: "Cut off the decoration. "

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

Dong.

Dai.

Dong.

Dai:

The filming was for filming, the taking was for taking, and there was also an observer peeking out of the door.

"Work hard!"

"Come on!"

"Brother, Captain Jiang is waiting for lunch."

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

The space in the bathroom was limited, so this was the only way to help the brothers.

"Wipe the sweat." Shen Yaowei stretched his head, holding the hammer with both hands, and it was not good to let the sweat drip onto the ground, because he would have to spray luminol again later.

The criminal police picked the ugliest one and went over to wipe Shen Yaowei's forehead with toilet paper.

"Go for the chisel. "

After a tile was broken, someone came to help and began to carefully remove the cement layer underneath.

Shen Yaowei gathered his strength and continued to work hard.

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

It can be seen that the suspect should have wanted to destroy all the old decoration and put on new ones, but he obviously underestimated the workload of the project, so only part of the old decoration was destroyed, and the final decoration was re-done on the damaged decoration.

Even so, a month's time is estimated to have kept Xin Shengsi busy.

Seeing this, Jiang Yuan said without waiting for all the demolition to be completed: "Spray some luminol and see."

Shen Yaowei hurriedly stepped out.

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

"Haha, as expected, they are all down there. "

The police officers present were happy.

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

Jiang Yuan immediately ordered people to take samples.

Shen Yaowei took advantage of the break to quietly send a message to his cousin: [Captain Jiang gave me credit again today. I feel embarrassed.]

[What's the situation?] Shen Yaoguo, the captain of the Changyang Public Security Detachment, replied to the information in seconds.

Shen Yaowei told what he had just done, and then said: [If you don't know, you would think we gave him a big gift. He takes care of me too much.]

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

Shen Yaowei's eyes lit up: [Yes, yes, yes, Captain Jiang was quite concerned about this before - Captain Liu even handled a few cases there to shock him. Will he look up to me for this reason? ]

Shen Yaoguo: [Don't let your imagination run wild. It must be! You entered the Municipal Bureau with the name of Yao, why are you pretending now? ]

Shen Yaowei smiled to himself: [That's right, it can't be because I'm a good shooter. ]

Shen Yaoguo: [So, I asked you to learn skills, but you went to practice shooting. I won't say more, I'll hurry up and prepare. Recently, the incidence of criminal cases in counties and districts has decreased, but the public security problem has been highlighted. ]

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

Shen Yaoguo: [Public security rectification activities, ready-made templates, specifically for these urban-rural junctions. Jiangcun Community is originally a public security depression in Ningtai County. I will take a team to help and plow them thoroughly. It would be best if the plow could reach the bottom and clear all the mud at the bottom. Those who fight and race in the early morning should all give out shit! 】
