Chapter 930: Confirming the Killer

"Team Leader Jiang, it's cut open."

Shen Yaowei broke three saw blades before sawing open the inner and outer plates of the deceased's cranium.

Jiang Yuan put down his teacup, sighed, started to put on his coat, gloves, and headgear, then took a T-shaped chisel, jammed it into the position where the cranium was sawed, and with a "ga" sound, pried the cranium open.

Shen Yaowei then stood up, found someone to help him wipe his sweat, and said: "It's like opening two coconuts with a saw, my arms are sore."

This work is indeed similar to opening a coconut. Both are to cut the skin and flesh wrapped outside, then saw open the hard shell, and then you can see the soft contents inside.

Jiang Yuan first carefully observed the dura mater under the cranium. The dura mater is a thin membrane, which is also similar to the white coconut meat after the coconut is pried open.

And the most common and basic surgery performed by neurosurgery is the subdural hematoma clearance surgery, cutting open the patient's dura mater, the purpose is to clear silt or release pressure, which belongs to the surgery that sounds high-end but actually has average technical content. Many hospitals with lower levels have voluntarily or forcedly carried out such surgeries.

Because subdural hematoma clearance surgery is an emergency surgery in most cases. To put it in plain and easy-to-understand words, it is falling on the head, the head being smashed, the head being kicked by a donkey, etc., which may require emergency surgery of this kind. Many local Health Commissions will require that within a city radius of XX kilometers, there must be a hospital that can do it, so as not to let patients die during transport.

And for forensic doctors, bleeding under the dura mater is also a very good indicator.

In most cases, finding bleeding under the dura mater can be used as the cause of death. Even if the deceased has other conditions that lead to death, a large mass of blood stasis in the brain still needs to be considered.

This is also the situation Jiang Yuan sees now.

"Blunt object hitting the head to death." Jiang Yuan cut along the midline of the dura mater, then used forceps to pull the dura mater, pulled it away from the arachnoid, exposed the cerebral hemisphere, gave the conclusion on the spot, and let Wang Chuanxing record it, and let the photographer next to him take pictures.

Click, click-click, click...

The photographer's SLR pressed out a series of shutters.

The light before sunset is the softest and most beautiful time, reflecting on the yellow, white, red, and black flesh, with a distorted and perverted stimulation. It's like a "sour toe cocktail"—when a human toe is soaked in whiskey, the human toe obtained through legal channels, the taste of this cocktail has long gone beyond the needs of the taste itself!

"Bag the corpse, add ice, transport it back, and let Wang Lan do the inspection material." Jiang Yuan checked several key parts again, basically confirmed that there were no other causes of death, and asked people to transport the corpse back.

The conditions on the scene were extremely simple, but compared to transporting the corpse back for autopsy, doing an autopsy on the spot can obtain conclusions several hours in advance, which is very beneficial for the advancement of the case.

Because the case itself is actually very simple. The deceased died in the eyes of a group of people, participating in a group fight and fighting with others.

Therefore, as long as the witness testimony of the bystanders is collected, and the people who participated in the group fight are found, the lower limit of the case is basically guaranteed. The slightly difficult place is who the killer is.

In fact, in the ordinary thinking mode of ordinary people, everyone who participated in the group fight is equivalent to a murderer, but the law is to find the implementer of the fatal blow, that is, the specific implementer of the lethal act.

For forensic doctors, it is to find the main cause of the deceased's death.

Assuming that in the last battle of the deceased, the neck was tightly strangled by Huang Zhong with a bowstring; the abdomen was stabbed by Zhang Fei's Zhangba Snake Spear; the left thigh was torn by Guan Yu's Green Dragon Crescent Blade; the chest was stabbed by Ma Chao's Tiger-Headed Golden Spear; the top of the head suffered a purple gold hammer from Li Yuanba; the left and right wrists were each cut with a large opening by Liu Bei's double swords; Cao Cao poured wine on him; Diao Chan twisted desperately under him...

Even if the bystanders know that people are killed by teamwork, they still want to find one person who is most representative as the murderer. At this time, it depends on the forensic doctor.

If bleeding under the dura mater can also be found, then Li Yuanba is the biggest suspect.

Su Shanming of the Changle City Bureau is the person responsible for finding Li Yuanba.

Qishan Village is still in the jurisdiction of the Changle City Bureau. Su Shanming followed Jiang Yuan over and had long been trapped in a vast number of cases, but this is a homicide case, so naturally, he had to give sufficient resources in the first time.

Su Shanming carefully selected a few police officers, and while rushing over, he exhorted: "Next, you guys will be responsible for this homicide case. I'll explain first, a homicide case is a homicide case, a homicide case is the first priority. Regardless of how chaotic it is here, what kind of people died, whether the person who killed is already going to be sentenced to death, these are not the problems you consider. You just focus on breaking this case!"

"Yes." A few police officers responded steadily.

The criminal police detachment is actually a relatively high-level investigation unit. The criminal police detachment at the prefecture level can even be considered the highest-level investigation unit on the front line, which can be said to be the elite heavy case group in fact. The cases handled daily are cases that district and county-level units cannot do. Homicide cases are not only not strange, but can be called professional.

A few people arrived at the scene, which can be called solemn.

Jiang Yuan had changed his clothes at this time, washed his hands clean, and wrote the first version of the informal report.

Seeing Su Mingshan coming, Jiang Yuan greeted him with a smile, then let Wang Chuanxing take things over, and said: "The cause of death of the deceased is blunt object hitting the head to death. The murder weapon should be a beer bottle or a round stick. The killer is taller than the deceased, not considering the standing position at the time, at least 10 centimeters taller, and the weight is relatively high..."

A few police officers were originally prepared to read Jiang Yuan's informal autopsy report in turn, but listening to what he said, they gradually stopped their actions and looked at Su Mingshan together.

Su Mingshan also frowned, not knowing whether he was angry.

In fact, Su Mingshan's forehead was indeed buzzing.

Mu Zhiyang had seen too many such criminal police captains, and said on the side: "Captain Su, our Team Leader Jiang is just so easy to use, you will get used to it later."

"Is it so easy to use?" Su Mingshan recalled the previous cases. After all, those cases were not led by him, and the feeling was not so deep...

Mu Zhiyang smiled and said: "How do you plan to do it next?"

"Next... there is nothing to do next." Su Mingshan sighed and said smoothly: "We have records of the people who participated in the group fight. Now it's to see who is the person holding the stick or beer bottle. Later, we will ask carefully about the process of the attack. If someone sees him hitting the head of the deceased, then it's basically stable."

"There is also the murder weapon." A subordinate reminded.

"Oh, yes, there is also the murder weapon. If it's a beer bottle, it's a bit difficult to find. Wooden sticks are okay. Will it be a wooden stick? Or something like a steel pipe?" Su Mingshan reacted and began to further confirm. In this case, if the murder weapon is found, the evidence chain of the case will be relatively complete, which can be said to be basically solved.

And compared to beer bottles, wooden sticks and steel pipes are obviously easier to preserve.

Jiang Yuan shook his head slowly and said: "The probability is still a beer bottle. This can be inferred from the form of the contusion..."

Jiang Yuan only said this much, looked up at Su Mingshan, and the desire to explain was greatly reduced. Thinking about it, he said: "This is not any high-level technology. The reason why wooden sticks and steel pipes are mentioned can only be said to have a very low probability. You guys consider beer bottles for the time being."

Beer bottle injury and even death is not a rare thing in the country. People who are drunk are prone to fighting and hurting people, and it is a common ecological mode of nightlife to smash people with a large green bottle that has just been drunk, or a large green bottle full of beer.

Therefore, in the forensic group, those with a little experience will also focus on observing and recording the characteristics of some common injury objects. Things like beer bottles are recognized by many forensic doctors at a glance.

Jiang Yuan had done a homicide case of beer bottle death before. Meeting it again this time, there was a feeling of solving the problem with familiarity.

However, after Su Mingshan relaxed, he began to feel a thick anxiety and couldn't help but say: "This beer bottle used as a murder weapon is probably not easy to find. Maybe it was smashed..."

"According to eyewitness data, the beer the killer drank that day was local beer. He didn't smash the beer bottle, but threw it into the garbage heap." Jiang Yuan paused here and said: "Fortunately, the garbage here is basically not processed. If you look carefully, it should still be possible to find that beer bottle."

Su Mingshan looked at the few police officers he brought with a bitter face, and then turned to look at the boundless garbage mountain.

A few police officers were surprised: "Captain Su, that's not what you said when you came..."

"If you don't have enough manpower, I can lend you a few people." Jiang Yuan coughed twice and said: "However, since you want to engage in garbage, it's better to do a garbage classification." ===== CHAPTER 931 =====
