"Go exchange some luminol."
Jiang Yuan turned around and gave an order, and asked someone to take photos of the bathroom again and again. Then three people squeezed into the small bathroom, each divided an area, and started checking.
Jiang Yuan only bent down to check the wash basin and floor drain, and then found a few corners to sweep before leaving. Then, another on-site inspection team from the Changyang Bureau came in.
When he was a novice and was working on a case, he did a secondary inspection of the bathroom. He and Wang Zhong wiped it with cotton swabs for several hours.
Now, he entered the scene with a Coaster for investigation. The suspect's residence was not big enough for everyone to work on their own, let alone have one bathroom per person. They all had to compete for the job.
Compared with the cases in Jiang Yuan's novice period, everyone is the murderer and the suspect, but the bathrooms of the suspects in the novice period were much bigger. Unlike the suspect this time, he only rented such a small room. If the room is smaller, the body will not be able to be placed, let alone dismembered.
It can be said that this house is an economical and practical dismemberment room. A smaller house or a house shared with others would not be suitable for dismemberment.
In today's cities with dense 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 a body. Furthermore, he is not qualified to premeditate murder!
"Captain Jiang, we found a woven bag of the same type." The technician who was searching in the bedroom pulled out a woven bag containing a woven bag from under the bed.
"Is this the one with the coating?" Jiang Yuan recognized it at a glance.
"Yes, there should be about 200 left in total. They are probably from the same batch as the woven bags where the bodies were dumped. We can take them back for testing." said the technician.
"Have you found woven bags from other manufacturers?" Jiang Yuan asked.
The technician shook his head: "No, only this one."
Mu Zhiyang said, "The suspect drives a truck. This is his own truck for transporting goods. Logically speaking, there is no need to buy so many at one time from two or three manufacturers."
"That makes sense." Jiang Yuan agreed. This was an inference that only required 0.01 Liu to make. It was estimated that the other two woven bags were obtained by the suspect from the victim.
Throwing the body twice means transporting it twice, and the woven bag used to transport the body the first time cannot be simply thrown away. Regardless of whether the body was dismembered when it was thrown away the first time, many friends who have never killed anyone do not know that in addition to blood, the human body actually has various other liquids and semi-liquids, which can flow out as the muscles lose their activity.
Therefore, the phrase "shit and urine flowing everywhere" can be said to be a powerful description of the human body's loss of control.
"Has the suspect confessed?" Jiang Yuan asked casually.
Some suspects will come to their senses after calming down in the police car for a while.
Wang Chuanxing came over and said, "I just followed up, and the suspect is keeping silent. But Captain Cao has already led the technical detectives to the community suspected to be the first scene. The suspect's phone was in the community for about 8 hours a month ago. In addition, a team of people also went to the warehouse area of the clothing wholesale market."
"Okay." Jiang Yuan nodded, looking relaxed.
Although there is no direct evidence yet, there is enough information gathered from all sides. Now it depends on which side can hit it.
Soon, the technician came back to report: "Captain Jiang, we are ready to spray luminol."
This thing is best viewed under dark lights, so what the technician actually meant was that I'm going to put everyone in a dark room.
Jiang Yuan agreed.
People on both sides began to spray luminol and then quickly pulled the curtains.
Nowadays, police officers generally don't use luminol anymore, because it is a freshly prepared solution. Although there is ready-made luminol "stock", it still needs to be mixed with sodium carbonate and hydrogen peroxide. Moreover, since it is a preparation, it has to be a little more particular, and the preparation of measuring cylinders and bottles is often a whole box.
In comparison, technicians doing on-site investigations now prefer to use multi-band light sources directly, which are the various types of exploration lights that Huang Qiangmin configured not long after he made money. Different bands can be adjusted, and different body fluids or liquids will emit light under light sources of different bands.
For example, semen fluoresces orange when exposed to visible light with a wavelength of 430 to 470 nanometers.
These are all based on the principle of cold luminescence, just like the glow sticks waved at concerts.
However, the use of multiple light sources for surveying has certain requirements for the amount of targets and relatively high requirements for timeliness. Simply put, if too little or too early is ejaculated, something like semen may be missed.
Luminol is different, you can see it in body fluids from a few years ago, and one drop is enough.
The bathroom is dark, without any blue light, which shows that the decoration of the bathroom does play a certain role.
But surprisingly, if not unexpectedly, there was a faint glow coming from the kitchen.
"There must be blood or something flowing on the ground." The two technicians were talking while taking pictures.
"It feels like a piece of pork belly fell to the ground." Maki Zhiyang also came over to see, with a smile on his face as if he were chatting with a social animal at work.
"It does look a bit like it." Jiang Yuan walked over to take a look, gestured, and said, "It's possible that when the murderer was cutting up the body, it was difficult to operate in the bathroom, and when he was taking some parts with a higher fat content to operate, the meat fell to the ground. Because the fat was smeared on the blade, the knife would become duller."
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. Maybe he forgot?"
Maki Zhiyang's smile during his daily work chats had long been restrained, and he only used the daily thinking of an ordinary non-legal medical type of office worker, saying: "Maybe he felt that there was meat and blood in the kitchen, so he didn't need to cover it up."
"Just do a DNA test." The forensic doctor who came with him said as he squatted down to take a sample.
Jiang Yuan watched with his hands behind his back the whole time. It can be said that his on-site survey level is already very high, but to be honest, this scene really does not require such a high-level on-site survey.
A group of people finished the sampling in a hurry, then returned to the bathroom, checked the sampling situation, and waved their hands and said, "Let's chisel away 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 and filming him.
thump.
Kaka.
thump.
Kaka.
Those who were taking videos were taking videos, those who were taking photos were taking photos, and there were also observers peeking outside the door.
"Try harder!"
"Keep working hard!"
"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 is limited, so this is the only way I can help my brother.
"Wipe the sweat." Shen Yaowei stretched his head. He held the hammer with both hands, but he didn't want the sweat to drip onto the ground as 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.
"Get the chisel."
After a tile is broken, someone will come to help and start carefully removing the cement layer underneath.
Shen Yaowei gathered his strength and continued to work hard.
Finally, under a large layer of tiles and cement, part of the old decoration was exposed.
It can be seen that the suspect had wanted to tear down the old decoration and put in new one, 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 would probably have kept Xin Shengsi very busy.
Seeing this, Jiang Yuan didn't wait for everything to be smashed, and said, "Spray some luminol and see."
Shen Yaowei quickly stepped out.
The technician took a small spray bottle and sprayed it with a hissing sound. Then he turned off the lights and drew the curtains. Then, dots of blue light appeared.
"Haha, sure enough, they are all down there."
The police officers present were delighted.
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 able to cover them up perfectly. The suspect's new decoration is actually a smart move, but in this case, it is just helping to 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 the credit again today. I feel so embarrassed.]
[What's going on?] Shen Yaoguo, the head of the Changyang City Public Security Brigade, replied immediately.
Shen Yaowei told what he had just done, and then said: "If you don't know, you would think that I gave him a big gift. He is so considerate of me."
[Don't say it, it's true. Let me think about it...] Shen Yaoguo's WeChat flashed, and after a while, he typed in the following content: [Jiang Yuan seems to be dissatisfied with the security environment in front of their Jiangcun community, and he has made a special report before.]
Shen Yaowei's eyes lit up: [Right, right, right, Captain Jiang paid a lot of attention to this before... Captain Liu even handled a few cases there to shock them. Could it be that he thinks highly of me because of this reason? ]
Shen Yaoguo: [Don't let your imagination run wild. It must be! You entered the city bureau with the name of Yao, why are you pretending now? ]
Shen Yaowei smiled to himself: [That's true. You can't blame me just because I'm a good shooter. ]
Shen Yaoguo: [So, I told you to learn skills, but you went to practice shooting. No more talking, I'll hurry up and prepare. Recently, the incidence of criminal cases in various counties has decreased, but the public security problem has become more prominent.]
Shen Yaowei: [What are you going to do? ]
Shen Yaoguo: [Public security rectification activities, a ready-made template, specifically targeting these urban-rural fringe areas. Jiangcun Community is originally a public security depression in Ningtai County. I will bring a team to help and plow them thoroughly. It would be best if we can plow to the bottom and clear all the silt at the bottom. Those who fight and race in the early morning will all be punished! ]
Today is the first day of hospitalization. I spent most of the time doing examinations. I waited too long...
