This is not that he is not proficient in learning and is not clear. It is really a home for ordinary people, and there are very few people who can use coal for heating in winter. And if there are people who die like this in the powerful family, most of them will hide and cover them, and rarely let people leak them out.

In this way, there are many fewer examples for the people to study.

Xu Chu saw that Song Derong was still displeased, and wanted to speak several times, so he simply took off his plain cloth gloves directly, and said coldly: "Of course, this is just one of the suspicions. ”

After speaking, she asked for the so-called confession from Xiao Qinglang again, and said, "Do you think that this confession was written by the deceased?" ”

Song Derong swept the suicide note, frowned and said, "Naturally." Although she was born in a peasant family, the official also asked his wife to ask Mr. Xixi to teach her. And the handwriting is not wrong, it is indeed written by her. ”

After hearing this, Xu Chu's heart suddenly became clearer, but it was precisely because of this clarity that she was even more confused.

If it was really as she thought, what was the purpose of the murderer doing such a series of things? Could it be that Aunt Liu is simply regarded as a scapegoat?

But this was clearly not the time for her to delve into those questions. So, she put down the doubts in her heart for the time being, and instead stepped forward and pointed to the confession and said: "There are many marks on this letter paper that have obviously been rubbed on the side of the palm, if it is really written by Aunt Liu last night, then there should be ink on her hand." However, please look at Aunt Liu's hands, which are clean and without the slightest ink. ”

"Didn't you say that Aunt Liu had changed her clothes before she died? Perhaps, she found that there was filth on her hands, so she washed it. ”

Xu Chu heard what he said, and immediately shook his head and said, "My lord, you can see that there is no bathroom in the room where Aunt Liu lives. Also, there was no water basin or bath in the house, and there were no wet wipes to wipe the body. ”

When the words fell, she walked straight to Xiang'er, who was kneeling in the threshold, and asked, "Did Aunt Liu call hot water last night?" Afterwards, did you call someone to carry the water away? ”

Xiang'er choked up, sobbed and replied, "No, the slave and maid slept outside, and woke up once in the middle to look at the aunt." At that time, the aunt was asleep, and the slave and maid rested again. Speaking of hitting here, she paused for a moment before hesitating and said, "At that time, the slave maid deliberately looked at the leaky pot, and it happened to be almost time. ”

"Have you come into the house and made sure that Aunt Liu is sleeping on the bed?"

Xiang'er shook her head and said a little sluggishly: "No, I just opened the curtain and took a look, and my aunt didn't move at that time, so the slave didn't enter the house." However, the slave maid was sure that the aunt was not hung from the beam of the house at that time. ”

Xu Chu nodded, and subconsciously glanced up at the roof. This roof is a flat-roofed house made of blue tiles that is common in the north, and not far from the bottom of the tiles is the beams.

In a flash of light, she suddenly connected all the clues of the case. It turns out that this is the case, and the murderer must have really taken great pains.

But at this time, it's not the time to talk about that. If Song Derong insisted on ending the case in the place where Aunt Liu committed suicide in fear of crime, then it would be difficult for them to solve the case.

Thinking of this, Xu Chu exhaled lightly, retracted his gaze from looking at the roof and said, "In addition, I have seen the stove used in Aunt Liu's room. There wasn't a lot of ash inside, and there was a slit in the window, so the room wouldn't produce enough carbon monoxide to be poisoned. ”

In other words, she was poisoned on the side.

"Now that she's been poisoned outside, either mildly or poisoned. According to her situation at the time, it was impossible for her to change her clothes by herself, let alone tie Bai Aya to the beam of the house and hang herself. ”

So, although she hanged herself, she was actually killed. And the so-called confession was also forged by the murderer a long time ago.

Xiao Qinglang's eyebrows moved slightly on the side, while Song Derong's brows furrowed more and more tightly, as if he was enduring something.

According to Xu Chu's words, Aunt Liu should have been trapped in a vigorous and relatively closed environment where coal was burning. Then, he lost consciousness due to poisoning, and when he was in a coma but still alive, he was arranged to commit suicide by hanging a beam.

"As for the fact that the ground is clean and has not left traces, it is very likely that the murderer wiped it before leaving. Or, the killer never entered the room in the first place. ”

"To sum up, all kinds of signs can show that Aunt Liu was killed by the murderer as a scapegoat."

Song Derong looked around and saw that the person who was originally disgusted also looked at him in shock, knowing that he was afraid that there would be no way to close the case as he wished. For a while, he also complained and disliked Xu Chu's ignorance of current affairs.

His eyes narrowed slightly, and he looked at Xu Chu coldly. saw that she seemed to have no feeling at all, so she just stood still and let herself look coldly. As a result, his brows, which were originally displeased, became more and more wrinkled, and his heart began to doubt.

On the side, Xiao Qinglang saw him looking at Xu Chu wantonly, and immediately looked cold, and said with a smile: "Don't be surprised, my lord, Xiao Chu often walks in the capital to visit the fierce luck, and even the flowers are quite appreciative of her. If the adults have a heart, they have probably heard about the time when Hua Guifei changed the time of the provincial relatives, it is precisely because Xiao Chu saw that there was evil qi in the northwest, and then concluded that the auspicious time given by Qin Tianjian was wrong. It is precisely in this way that she can make the playboy treat her with courtesy. ”

As soon as Song Derong heard this, he immediately reined in his dark thoughts. If he can be valued by the public and put in the position of a state general judge, it is naturally impossible for him to be a person with a full stomach of straw.

He knows that all the masters are different. Thinking of the situation when Xu Chu saw the corpse, and Hua Wuxi's admiration for her, the little speculation in his heart also dissipated.

Even if he doesn't believe Zhou Yunlang, he also trusts the hidden stake inserted by Rong Gong'an in the household department. What's more, a person who deals with ghosts, ghosts, and corpses can't be someone with any background at all. What's more, if she is still a woman, it is even more impossible to ascend to the hall of elegance.

He weighed too much in his heart, and he couldn't brush off the face of a dude. Second, he also wanted to use this to win over the playboy for his use. Three, under the current circumstances, it is impossible to cover Aunt Liu's death tightly.

Thinking about it, people cannot be offended. Since this carriage does not work, then he is afraid that he will have to start from the side.

Thinking of this, he coughed lightly, the dark clouds rolled under his eyes, and after a while, he said: "It's that the official is too eager, since you have eyebrows, then please leave this matter to the two." In this way, the official left first, and the official affairs in the yamen were busy, and the official could not tolerate the delay for several days. ”

After Song Derong left, the tense atmosphere in the room dissipated suddenly. Only Xiao Qinglang, who was thoughtful, was left, and Li Yanzuo, who eagerly discussed the autopsy with Xu Chu, was still bright-eyed and couldn't wait to apprentice immediately.

"The color of the corpse spots is abnormal, how did the girl deduce the time of death from the corpse spots?"

"It is too limited to determine the time of death based on corpse spots alone, and at the same time it depends on the zombie, changes in acupressure, and changes in the temperature of the corpse's eyes, lips and lips. If these factors are disturbed by external factors, then the autopsy is carried out to see how well the food is digested in the stomach of the deceased. For example, if the shape of rice and vegetables is intact and there is very little erosion, the time of death will generally be between half an hour and an hour after the meal. However, if all the food in the stomach is chyle-like, and there are only a few residues, and most of them go into the large intestine, then the time of death can be inferred to be death two hours after eating. If the deceased had not eaten for a long time before his death and had no food to use as a reference, then the bladder can also be dissected and inferred from his urine and urination habits. ”

She paused and said with a smile: "Of course, the last method is more accidental. Generally, it is only forced to use it out of desperation and there is no other way. ”

Li Yanzuo is also a humble person, and he hurriedly wrote it down when he heard the words. However, although he admired Xu Chu's ability, he also had some doubts. How could such a woman with clear eyebrows and a quiet moon be so precious at the time of the autopsy?

If she had just followed the records in the autopsy book, Li Yanzuo might have felt relieved, but not so surprised. Partial birth, what she said, many techniques, not to mention that they have never been recorded in the classics, and even if there were, they would not be so detailed.

In his experience, it would have been impossible to draw such detailed conclusions if he had been in contact with and had dissected and studied various corpses.

However, just when he was stunned, Xu Chu had already stepped forward to look at the strips of corpse spots again. She always felt that the corpse spots on the deceased's abdomen were a little different and too regular.

After thinking about it, she simply reached out and pressed it again, and found that although the skin did not have a bulge or scar, the color of the corpse spot did not change at all. And the corpse spots on the side are somewhat faded.

However, because of the different colors of the corpse spots and the fact that the time of death has exceeded five hours, the acupressure of the corpse spots has not changed much. In this way, she naturally needs to be more cautious.

After thinking about it, she simply took the autopsy knife again and lightly scratched it on the corpse spot on Aunt Liu's body. But I saw that the original bright red place suddenly flowed out of a layer of blood.

Just when Li Cheng was dumbfounded, Xu Chu's eyes sank.

She took a clean handkerchief and wiped the bleeding blood, only to find that it was barely clean. Suddenly, another layer of blood flowed out.

"Sure enough." She meticulously treated the wound, and then gently pressed on the bright red spot next to it, but there was no such phenomenon.

Seeing this, Li Cheng hurriedly said: "How can there be blood oozing from the corpse spots?" ”

At present, it is very rare to study the corpse to the extreme, and even the cases of disemboweling and disemboweling with a post-mortem knife, or even cutting the surface of the body are very rare. Therefore, in terms of what a forensic doctor like Xu Chu who has experienced meticulous study has learned, even if Li Cheng is such a studious person, he can't match it in the autopsy.
