Moreover, Xu Chu's autopsy, unlike the pretend, she would not care about the identity and gender of the deceased. It can be said that as long as the truth can be tested, she has no taboos. It is precisely because of this that her inspection is so careful that even Li Chengzuo is ashamed.

Xu Chu didn't look at him, and directly pointed to the traces on the deceased's body and said, "It's not corpse spots, it's blood." ”

She folded the handkerchief aside, pointed to the wound she had cut and said, "Subcutaneous hemorrhage, caused by a ring-shaped soft object, three fingers wide." The strangulation marks are from the bottom up, starting from the left and right ribs of the abdomen, and there is no intertwining. It should be similar in texture to white silk. ”

After saying this, she looked up and found that Li Yanzuo was still puzzled, so she simply explained patiently.

"Although corpse spots are caused by blood sinking before it coagulates, it is impossible for blood to seep like this if the blood vessels are not broken. Even if the blood vessel is broken, it will only ooze blood or blood droplets, which is easy to wipe and clean. The subcutaneous hemorrhage is different, because there has been a subcutaneous injury before death, so there will be blood accumulation under the skin. ”

And to judge the difference between the two, you can look at the part where it appears. The corpse spot is located in the sunken part of the corpse, and the boundary is unclear and irregular. Injuries are the opposite. Second, you can see its color, within five hours, press with your fingers, the corpse spots will fade, but the traces caused by the damage will not change. Third, it can be cut open to observe whether there is a blood clot inside and whether there is blood accumulation. ”

And it was the third method she used.

"But if that's the case, why isn't there whitening on both sides of the scar?" Li Qizuo put away his stunned expression and hurriedly asked shamelessly.

Xu Chu only listened to his question, and knew that this gentleman must have real talent and learning. If it weren't for the fact that she was a human being in two lives, and she took the opportunity to study forensic medicine in her previous life, I am afraid that she would not dare to exaggerate in front of him at this time.

Thinking of this, Xu Chu continued to analyze: "So, I said that the deceased was hung on the beam of the house before he was poisoned but did not die, and pretended to hang himself. ”

"The murderer did not enter the house, but tied the person down directly from the roof." She reached out and made two gestures between the deceased's abdomen and continued to say, "At that time, the deceased was in a coma and could not resist moving. And the murderer took advantage of this time to move her to the roof, and then took the first white silk and threw it from it, and then tied it up with something. After the set was ready, she took another white silk and put it on the deceased's abdomen and slowly lowered it, putting the deceased on top of the white silk. ”

Li Qizuo suddenly realized, and suddenly said: "Therefore, the knot will be offset." ”

Xu Chu nodded, and seeing that everyone was looking at the roof thoughtfully, she continued: "At that time, there were two murderers, one pulled up the tied white silk on the beam of the house and put it around the neck of the deceased. The other tugged at the white silk wrapped around the deceased's abdomen. It was this that caused a scar to appear on her abdomen that was pulled up from the bottom up. ”

"That's why, there are no marks in the deceased's room, but there are wet marks on the floor." She couldn't help but smile when she saw Xiao Qinglang's eyebrows bloom. When he looked at the subordinates of several guards and Song Derong's cronies, he immediately smiled and said calmly, "As for the evidence, the most obvious thing is that the clothes taken off by the deceased are a little damp. If you don't believe it, you can also untie the white silk on the beams of the house to inspect it, and there must be traces of rain soaking on it. ”

Now she didn't need to say anything, but she saw Song Derong's henchmen standing on the stool and untying the white silk, and sure enough, as Xu Chu said, it was very wet.

By this time, almost no one questioned her reasoning anymore. On the contrary, everyone was amazed at her perceptiveness and meticulousness, and she deduced so many things just by looking at the corpse.

So, whether it was a subordinate, a guard, or even an official, they forgot the nausea she felt when she wiped the corpse's feces just now, and looked at her with great surprise.

How did this girl grow up, it was rumored that she had a three-foot nether ghost fire on her body, which could incinerate all evil ghosts. But when they saw it, she was just an ordinary woman, at most a little more extravagant.

But now it seems that they underestimated her.

Just when everyone was making up their brains, Xu Chu opened his mouth and asked people to get a ladder to come.

But she didn't think about it, Xiang'er, who had been worried about crying and crying, suddenly said in a hoarse voice: "There is a rockery behind the house, and there is a ladder on the side." ”

Xu Chu glanced at her and asked her to get up first and wait for her to come back and ask questions. Then she walked out of the room without saying a word, this courtyard is not big, so she doesn't need someone to lead the way, she found the ladder in Xiang'er's mouth.

The ladder was drenched in rain and snow for most of the night, and it was already wet. And the ground around it is also muddy.

Before everyone could get closer, Xu Chu hurriedly shouted for everyone to stop and not to step forward. Just when everyone was puzzled, she walked straight to the bottom of the ladder, crouched down and stretched out her hand to measure something.

After a long cup of tea, so that many people were whispering, she got up and pointed to the ground and said, "The ladder has been moved, and the corner of the ladder is half an inch into the dirt." It can be seen that after the rain and snow began, some people carried heavy objects up the ladder. ”

"There are several footprints on the lower right side of the ladder, of various sizes."

Everyone followed her gaze, and sure enough, they saw a few clear footprints scattered on the dirt floor. Looking in the direction of those footprints, there are a few traces of mud stains on the rockery stones.

Further up, there was no trace.

Xu Chu didn't care about the mud stains, but repeatedly checked the footprints left at the scene.

Xiao Qinglang was not surprised by her reaction, for her ability to break the murder with her footprints, he had already seen the scene where the bones were scraped alive during the White Bone Case.

Now, as long as he thinks that she will be amazing again, Xiao Qinglang can't help but feel a sense of honor in his heart. So much so that the coldness that Song Derong looked at her wantonly before was replaced by the eagerness in his heart.

"I need the plaster powder used by the craftsmen, and then I have people prepare water and oiled paper, and get some fine wooden sticks." Xu Chu looked at the footprints on the ground and spoke in a solemn voice. At the same time, people brought pen and paper to copy out all the footprints on the mud floor.

It was only after collecting the paper of the footprints that she had drawn that her expression became more and more cold. It seems that the murderer is more cunning than she thought, but unfortunately, the footprint identification will never be deviated because she wears shoes of different sizes.

After all, a person's footprint will always be limited by her height and weight, as well as her walking posture and various habits.

In the past life, footprint identification was already an extremely mature science, and even existed as evidence in litigation. Nowadays, due to limited conditions, many footprint extraction and identification methods cannot be used.

Only copying can be used as a substitute for taking pictures, and plaster modeling can also solve the problem of extracting footprints from clay floors. Just as she was thinking, the next person who went to get the gypsum powder also hurried back.

Xu Chu put five points of water, mixed three points of gypsum powder and stirred, and when it became a slurry, he turned around and asked Xiao Qinglang to step forward with Xiao Mingzhu and help surround the footprints with a thick layer of grease.

When everything was ready, she carefully found the lower side of the footprint and slowly poured the plaster slurry in. Seeing that the slurry was attaching an inch too fast, she carefully put the thin wooden stick sent by her servant into the skeleton, and then continued to grout.

By the time she had done it over and over again, the first footprints that had been grouted had solidified into a mold. She wiped the model she had taken out, and it was a copy of the marks on the ground.

"Although the footprints are large and small, in fact, all the footprints are left by two people. The first of these, the closest to the ladder, is the normal footprint of one of the murderers.

"The footprints are narrow and short, the starting and landing feet are even and light, the bow pressure is wide, and the stride length is short, which is typical of women's walking. In addition, the footprints are seven inches and one foot and four minutes long, so it can be speculated that this person was about five feet long. This is the first time that Xu Chu is glad that the Great Zhou Dynasty does not have the rules for women to bind their feet, otherwise, her inference will be greatly reduced.

"The stride angle is small, narrow and shallow, and there are pedal marks, so it can be inferred that this person is thin."

"He is about forty-five years old, in good health, calm in temperament, and does not panic at all."

After speaking, she didn't care how much others understood, and continued to change her footprints and said: "The other person, female, is a little older, about sixty years old. There should be an injury to the right foot, resulting in a much heavier footprint on the right foot than on the left. Based on the length of his feet, he is about 4 feet 8 inches tall and has a thin body. But...... Strangely, the footprints resemble ...... It seems very deliberate. ”

"Hey, how does Sister Chu know?" Regarding Xu Chu's ability to look at footprints and recognize the murderer, Xiao Mingzhu has long been puzzled. If you want to say that the last time was a fluke, then this time there were so many footprints, she didn't see the reason for it for a long time, how could Sister Chu see so many doorways when she looked at it?

Xu Chu looked up and saw that she and Li Cheng were both dumbfounded and waiting for an answer. Putting aside the doubts in her mind for the time being, she explained while putting away the footprints she had collected: "Generally speaking, adults are seven times as long as their feet. But to be exact, it's 6.876 times. There will be some differences between children and the elderly, but the differences will not be too big. As for the body type, it can be guessed by looking at the depth of the footprints and the foothold. In terms of age, it can be summarized that middle-aged people will walk steadily and slowly, and even if they walk casually and destroy the scene, the distance between their steps will become shorter. Older people will only have a shorter stride and a heavier heel than the ball of their foot. ”

"Gender judgment is simpler, and there is a clear difference between women's steps and foot shapes and men's characteristics. What's more, there is also a difference between the women's embroidered shoes and the men's boots. As long as you observe these carefully, it is not difficult to draw conclusions. ”

Xiao Mingzhu listened to it with relish, and Li Chengzuo made this a treasure. He was now very convinced of Xu Chu, and just wanted to see if the results were as she had speculated, so that he could determine whether he would use this assertion in the future autopsy process.
