"Captain Lin, what kind of method is this? What's the use of sticking cakes on the corpse?" Zhang Wenkai approached Lin Mo and asked in a low voice.
Yu Chengjie, who was on the side, also moved closer. He had been working in the police station for more than ten years. He had seen autopsies and the like before, but this was the first time he had seen this.
"This is supposed to be a method of injury detection, which allows the subtle injuries that cannot be observed with the naked eye to appear on the corpse. I don't know the specific principle."
"Is there really any injury? I've seen it before, but you can't see it at all?" Yu Chengjie thought for a while before asking in a low voice.
Lin Mo heard this, thought for a moment, and then replied: "The human body is far more fragile than imagined in some aspects. If you scratch or pinch it with just a little force, damage will occur under the skin.
It's just like a bruise, but it's too slight and won't show surface features like a bruise. However, some methods can be used to strengthen this feature and make it appear.
Of course, this refers to the corpse state, because minor injuries will recover and disappear quickly. However, if the person is injured a short time before death, the blood stops flowing and the vitality dissipates, these injuries will be left and preserved.
Although Dacheng has no physical scars, if he did not die in an accident, no matter what means the other party used to control him or murder him beforehand, it is very likely that he would have left such injuries, and this is what we have discovered now."
Yu Chengjie nodded slightly and said no more. Lin Mo also cast his eyes on the three people who were waiting and discussing in low voices. He was just about to go over, but the three people moved again.
Get paper, bake cakes, and then cover Kuang Dacheng's face. After doing this, let Cheng Huatao and two people take care of it, and Song Ming took the initiative to come over.
Song Ming took the initiative to explain to them the autopsy method used. The method used was the plum cake injury examination method in the collection of records of the redress of grievances.
The so-called plum cake is made by mixing white plums, green onions, peppers, salt, distiller's grains and other ingredients and grinding them into pieces to make pancakes. This is plum cake.
Then put the plum cake on the fire to heat it, then use paper to line the parts of the body that need to be examined, stick the cake to the paper and iron it, and the scars will be revealed.
Lin Mo nodded slightly and asked: "Can we use scientific methods to study these ancient books, study their principles, and then use this to find a more time-saving and labor-saving inspection method."
When Song Ming heard this, he was slightly stunned. He really hadn't thought much about this aspect, but he also received a Western education and didn't think it could be done.
After careful consideration, Song Ming nodded slightly and replied: "It should be feasible, but there is no guarantee of results, and the cost may be quite high."
Lin Mo heard this and said with a smile: "There is no need to worry about funding. I will write a plan report when I get back. The boss should be able to approve it. The same goes for the two of you. Please convey what you need. You don't need to hide it. You can just
Submit it to the office."
Boss Dai also gave the forensic doctor a department title and called it a research laboratory. He obviously foresees the role that they and others can play, and there is no shortage of money at the moment, so there is a high probability that he will not refuse.
Song Ming nodded, but did not talk much here. Instead, he introduced the preliminary results of the autopsy to Lin Mo.
According to Song Ming, based on the multiple characteristics on the corpse's surface, it can be determined that Kuang Dacheng did indeed drown. As for what happened before he drowned, further investigation is needed.
After chatting for a while, Song Ming went back to take care of the body, looking around from time to time, and then asked Yang Rui to bake plum cakes. He told Lin Mo that the body was kept in ice and the body temperature was low.
Needs to be ironed again.
When it comes to professional matters, it is natural to listen to the professionals. Lin Mo did not raise any objection and honestly waited and watched them busy.
"...I found something..." After the second round of ironing was over and the plum cakes were peeled off, Cheng Huatao spoke. Lin Mo stepped forward immediately. Zhang Wenkai couldn't help but stepped forward. Even the family members looked at each other, curious.
Looking around.
As the plum cake and paper were peeled off, some marks were clearly revealed on Kuang Dacheng's skin. Although they were slightly faint, they could be distinguished from the surrounding normal skin.
The more it was uncovered, the more traces were revealed. There were two large bruises on the outer and front sides of both hands and arms. There were also bruises on the chest, but they were obviously smaller and shallower.
There are also several spots on the neck, but they are all very small. The big ones are only as big as a fingernail, and they are gestured. They are not related. They should not be pinched out with fingers. They should be caused by accidents. There is a high probability that they are also related to the case, but basically
Exclude the other party from doing it intentionally.
There were also marks on his face, around the mouth, large and small, in patches, almost surrounding the entire circle. Lin Mo observed carefully and made signs.
Judging from the scars, it is likely that someone used his left hand to wrap his arms around Kuang Dacheng's torso and control him from behind, and covered his mouth with his right hand.
But looking at these marks, Kuang Dacheng did not resist for too long and was quickly and completely controlled. There were no ropes or other signs of binding on his body. Song Ming had also checked before and no foreign objects had been inserted into his mouth.
Lin Mo suspected that the other party may have used some kind of drug to make Kuang Dacheng completely lose consciousness and resistance, and in a very short period of time, he was completely unable to resist. Otherwise, it would be unexplainable why there were so few traces left.
As for what kind of medicine was used? How was it ingested? Lin Mo suspected that it might be a powerful narcotic drug and was ingested through mouth and nose breathing.
If intramuscular injection is used, the effect may not be as fast, and Kuang Dacheng will also resist violently. This method should leave more traces of control.
Both of them, if the injection is done in a very hidden position, there will be more traces of control on the body. If not, the needle holes may not be hidden.
In this era, the needles used for intramuscular injections were not the thin ones used in modern times. After the injection, the needle hole was basically invisible. The needles used in this era were still relatively thick. If they were not in a hidden position, they could be found by the police when examining the body.
As for force-feeding it into the stomach, it is unrealistic. Not only does it take a long time to take effect when it enters the digestive system, Kuang Dacheng will not swallow it easily, and force-feeding it will inevitably leave traces.
This chapter is not finished yet. Please click on the next page to continue reading the exciting content! Therefore, the method used by the suspect is most likely to put a highly volatile anesthetic, such as ether, upside down on a hair string or the like, and cover it with
Cover his mouth and let him breathe in the anesthetic.
Using this to quickly control the person can also explain the problem of many scars around his mouth. He should have realized something was wrong and resisted vigorously.
In addition, there are indeed scars on his waist, but there is a long strip on the lower waist. It looks like it was pulled out by a belt. After Yang Ruibi gestured for a scratch, he wanted to say something, but Lin Mo raised his hand to stop him.
.
"...Sir...I...my brother was really killed by someone?" Seeing Lin Mo coming over, the second son of the Kuang family said with some anxiety.
"...Well..." Lin Mo nodded slightly, without concealing anything, and said: "It's confirmed, I won't say more about this for now, I need you to leave first, we have some situations that need to be discussed.
Don't worry, nothing will be done to your brother's body. Officer Yu will stay and watch. You go outside and wait for a while. It won't be too long. Remember not to spread the word about the situation."
"...Okay..." Kuang Laoer hesitated for a moment and nodded in agreement. Next to him, Kuang Dacheng's eldest son knelt down in front of Lin Mo with a plop.
"...The man has gold under his knees... Hurry up and get up first..." Lin Mo quickly helped the man up, but when he couldn't help it, he dragged him up.
"Don't worry, the person who murdered your father will be caught. Now go out with your second uncle."
"...Hmm..." Lin Mo comforted him with a few words. The young man sobbed and nodded. He turned around and was led out of the door by Kuang Laoer and Yu Chengjie.
Lin Mo explained his reasoning to Song Ming and others, and asked them to conduct a comprehensive and detailed inspection of Kuang Dacheng's body to rule out other possibilities.
The three of them nodded in agreement, took off everything Kuang Dacheng was wearing, and inspected it carefully. In the end, no needle holes were found.
After confirming the situation, Lin Mo looked at Yang Rui, who quickly explained the situation, which was about the scars on Kuang Dacheng's lower back and the marks on his belt.
According to him, when he checked the belt before, he thought that someone had pulled the belt from behind because of the marks on the belt.
But the traces left by the belt are obviously not like this. The pulling should be on the front. If so, the traces on the belt are a bit special.
Because the belt is made of pure cowhide, it is very tough and strong and will not easily leave marks. However, the fact is that there are very consistent fresh marks on both sides of the belt buttonhole.
This mark is unlikely to be left regardless of whether the belt buckle is lifted individually or on either side, unless both sides of the belt buckle are lifted at the same time.
But in this case, it would be extremely awkward for one person to lift it, and it would not be consistent with the scars left on the lower back, let alone one person lifting a person weighing more than 100 kilograms. Therefore, the murderer should have more than two people, one person lifting one side.
"...Also, I can't figure out why they lift it from the front. Logically speaking, it should be more reasonable to lift the belt from the back."
After listening to this, Lin Mo thought carefully for a while and said: "There is a high probability that there are only two suspects. At that time, Kuang Dacheng should have completely lost consciousness, or at least lost control of his body.
If you lift it from behind, the person may bend like a prawn, making it more difficult to control. However, if you lift the belt from the front, it is different. At least the torso and thighs will not bend, and you can just hold on a little.
Moreover, this can also explain the drag marks on the heel of the shoe. I estimate that the heel was pulled on the ground, or was scratched elsewhere due to his position."
After Lin Mo finished speaking, Zhang Wenkai, who had already come up to him, couldn't help but ask: "Why don't you use it on your back? That should be easier, right? One person can control him, so he should be able to carry it on his back, right?"
Unfortunately, after Zhang Wenkai finished speaking, he was not greeted with applause or appreciation. Even if everyone was wearing masks, he could feel the speechlessness on everyone's faces.
Zhang Wenkai shrank back, and he didn't think about what was wrong. He knew that Kuang Dacheng weighed only more than 150 kilograms. Although he was a little heavier than ordinary people, he couldn't weigh much? A person of this weight
