National Forensic Doctor

, update the latest chapters as soon as possible!

In the forensic autopsy room in Changyang City, there is a corpse on each of the three autopsy tables.

Not counting the first body that had been put away, the bodies of three other hammer-killed victims lay here.

Among the three people, one was dug out of Jianghua Kechuang Building and was the project manager from Xinxin Construction and Decoration Company, and the other two were foreman of another company, day and night decoration design company.

The positions are slightly different, but their job content includes communicating with wall builders.

Coupled with the almost similar methods of killing and burying corpses...

These three corpses, plus the corpse of a project manager in Shang Geyong's home, were all identified as the work of wall builders and disposed of.

Although they had expected it, Jiang Yuan and others still felt the pressure of silence when looking at these three corpses.

Even for a provincial capital city like Changyang City, one corpse and four corpses is still a case that needs to be taken seriously.

"Qian Da's phone number." The landline phone rang in the autopsy room. The forensic doctor next to him took a look and handed it to Jiang Yuan.

Jiang Yuan took off his gloves and hood, took a break, picked up the phone, and said, "Money is big."

Qian Tongyi took a deep breath first, as if he was very tired, and said, "How is it? What's the conclusion?"

"To draw a direct conclusion, first of all, it is confirmed that the four corpses were all caused by the same murder weapon, which is the hammer we identified before. It should be regarded as the usual equipment of the murderer, and it is likely to be carried with him." Jiang Yuan removed the skulls of the four corpses. After comparison, we are very sure about the murder weapon.

Qian Tongyi said "hmm" and said: "This conclusion is very important, but I don't know if the murderer would have carried this hammer with him on his escape. If he did, he would not be able to take the high-speed rail or fly."

Jiang Yuan pouted, now is not the time to worry about this at all. Furthermore, the murderer now still has Shang Geyong with him...

Thinking of this, Jiang Yuan frowned and asked, "Have you concluded that Shang Geyong is dead?"

"It makes no sense to die." Qian Tongyi said: "The murderer brought him with him. He was just a burden and very dangerous. He has killed so many people, and Shang Geyong is no less. Of course, it is also possible that Shangge used This is better if Yong is the driver, and we are now actively contacting Pingzhou."

Shang Geyong's car has never been found. To the police, this means that the car is either parked somewhere and not moved, or it has been dismantled, or it has been moved to a place like Pingzhou where birds don't poop. possible.

Otherwise, if you drive south and east, there will be more and more cameras on the road network in various places, and it is impossible to have no news at all.

Jiang Yuan nodded slightly on the other end of the phone and said, "Indeed."

In Jiang Yuan's view, Qian Tongyi's logic was sound. The only reason the murderer took Shang Geyong away was because Shang Geyong saw something he shouldn't have seen, and the murderer had no time to deal with Shang Geyong.

It has been several days now, and Shang Geyong is most likely buried somewhere. The best thing about life is to be a driver. If it is neither of the above, the problem becomes complicated.

"Our current work focus is divided into two parts, one is to chase the murderer, and the other is to find other corpses." Qian Tongyi updated his work here, and continued: "There will be more corpses. ,Right?"

"I guess so." Jiang Yuan sighed and said: "The four corpses discovered now are basically of a similar pattern. Except for No. 3, which was built in the bay window, the others were built inside the wall, and they were all done. Anti-corrosion treatment is a relatively mature model and is not something done by novices.”

Qian Tongyi said "Eh" and said, "It's a good idea to build it into the bay window. If I open a few holes on the outer wall, won't the smell in the house stop?"

"Opening holes will intensify the decay of the corpse, and the initial smell will probably be stronger. Especially on rainy or hazy days, the corpse is prone to moisture return." Jiang Yuan paused and recalled: "Insects can also easily get in. , then a large amount of insects or excrement may leave traces on the exterior wall. I can’t say for sure, no experiments have been done. But I think the murderer may not have thought so much.”

"Well, this is really possible." Qian Tongyi sighed and said: "We are currently getting to know some people from decoration companies and workers in the market. The murderer calls himself Lao Chen, who is from Jianxian County. Changyang City is not too far away. Most people call him Lao Chen or Master Chen. He has mentioned his name, but no one remembers it. It is said that he is a taciturn person who doesn't like to talk and can't say a fart in three sentences. The workers think this kind of person is a bit stupid and don’t like to have contact with him. He doesn’t smoke, drink, gamble, or play with women. Do you feel that you have some mental problems?”

"Just work, no entertainment or leisure, how about sending the money back home?"

"It is said that he has no wife or children, and his parents are no longer here." Qian Tongyi couldn't help but said after holding back his words, "The Lone Star is really difficult to deal with."

Jiang Yuan was silent for a few seconds and said, "In this case, he should have a lot of money in his hands. Why is he still doing odd jobs in the market? This job is not easy."

"Are all serial killers like this? They just like stable jobs."

"Although that's not how it's expressed, it's what it means."

"So, what we are facing now is a typical serial killer who has no organization but likes a stable job?" Qian Tongyi thought of this and simply said: "I will spread out more people and look for several building materials markets near Pingzhou. .”

After working with Xu Taining, Jiang Yuan now listens to Qian Tongyi's troubleshooting. It feels like playing. Just guess a place. How can the success rate be guaranteed?

But the reality is that Xu Taining's success rate is high, but the cost is even higher.

If Xu Taining were to follow this line of thinking, he would have to visit and investigate a person in the building materials market in multiple cities, even cities in two provinces. Think about it, even Xu Taining would not do such a thing. He must have Just narrow down your goals.

Jiang Yuan looked at the corpses on the autopsy table and said casually: "Think about it, this wall builder doesn't seem to understand high technology, but he knows how to change his phone number and cell phone. To say that he understands this, he doesn't even know how to do it. No WeChat or QQ? Does he pay in cash?"

"That's right, this guy doesn't have Alipay or WeChat, so he has to use cash to spend money!" Qian Tongyi said helplessly: "I set up a portrait alarm. I'll see if I can run into him later. I just need to identify a city. It’s easy to find.”

"If it's just to determine the city, I have an idea." Jiang Yuan had been thinking about it just now.

Several of the corpses were in a mummified state, but because the identity of the missing person was available for comparison, it was easy to trace the source of the corpses. In addition, the manner of death was also determined, so there was actually very little room for forensic medicine to play its role.

However, the lime smeared on the mummy made Jiang Yuan think about it after being exposed to it too much.

At this time, since Qian Tongyi's request only reached the city level, Jiang Yuan thought: "I noticed that the lime on the corpse, especially the lime smeared into the abdominal cavity of the body, is all pink lime. This is probably The murderer purchased it himself or requested it.”

"What is pink lime?"

"I also found out after checking the information that lime can be divided into lump lime, fine-grained lime and pink lime according to its fineness. In some decoration places, pink lime may not be used, but after the murder, the murderer smeared all the It’s pink lime…”

Qian Tongyi suddenly became energetic: "So the pink lime was brought by the murderer?"

"It's possible. Because there were two types of lime at both scenes, and the lime used to smear the abdominal cavity was basically the same kind, which shows that the murderer had requirements for lime. In addition, lime is divided into high-heat lime and low-heat lime. , divided into under-fired lime, normalized lime and over-fired lime... In short, the murderer has clear requirements for lime. I will send you the specific content soon. Visit the market and see if you can buy the same kind of lime with cash. people."

"This is good, this is good." After Qian Tongyi finished speaking, he hesitated and said: "His purpose of buying lime was probably to wipe the body. On his way to escape... he might not have done it immediately."

Jiang Yuan sighed: "I haven't found Shang Geyong yet."
