Yang Qiuchi ordered that these death penalty cases be suppressed first, and when he was empty, he would have to review them in detail, and then ordered that the case file of the murder of Xulingzi be transferred. Pen, fun, pavilion www. biquge。 info

The clerk of the Yamen Torture Room hurriedly transferred the file and presented it to Yang Qiuchi, and sealed it in a large envelope, and it could be seen that there was not much in it. Yang Qiuchi opened the envelope and poured the contents on the desk.

Inside was a dagger stained with yellowish bloodstains, several testimonies, and a corpse.

Yang Qiuchi first lowered his head and carefully inspected the dagger, this dagger has two blades, there is a blood groove in the middle, the pale yellow blood mark is located in the front half of the dagger, the blade is very small, in order to increase friction and prevent sliding, the handle is wound with a thick red wire.

This one was kept and checked later, Yang Qiuchi picked up the corpse grid first, although the ancient corpse grid listed many matters that needed to be recorded, but the requirements were not detailed, and the record was very rough. It only briefly recorded the time and place of the crime, the identity of the deceased, the physical examination, and the examination of officials, abusive deeds, and witnesses.

The physical examination is what Yang Qiuchi is most concerned about. But he only remembered one sentence: "A dagger is inserted in the left heart." This is too simple, there is no specific wound location, shape, size, etc.

That morning, the maid who was waiting outside the house saw that there had been no movement in the new grandmother's house, and the maid who was waiting in the house was gone, so she called the door, and the door was bolted from the inside, and went around to the back window, and found it open, and looked inside, and found that the new grandmother had been killed. This is consistent with Xue Lu's statement.

Several other testimonies were of little value either.

Although the fingerprints and other traces on the dagger were likely to have been messed up by the catchers who extracted the dagger, Yang Qiuchi still habitually wrapped the dagger with a sweat towel and put it in the envelope, and then put the testimony and corpse in it, and handed it over to Song Yun'er for safekeeping, preparing to carefully analyze and study the dagger after returning home.

Subsequently, Yang Qiuchi ordered the arresters who participated in the on-site investigation that day to be called and took ten fingerprints of each person.

It's all over, and it's time to open the coffin for an autopsy. Xue Lu had been sending people to follow Yang Qiuchi and them, and after they were done, he led them to the cemetery outside the city where the Void Lingzi and the two maids were buried. Since Xulingzi was only a concubine of Xue Lu, he could not be buried in the ancestral tomb of the Xue family, so he found a feng shui treasure outside the city and buried it.

Xue Lu had already taken his own soldiers and servants to dig up the three graves, and the coffins had been lifted out and put aside.

After Yang Qiuchi arrived, he ordered all three coffins to be opened and the smell was dispersed first.

The coffin has only been buried in the soil for about half a year, and it has not yet decayed. The coffin lid was pried open, and a corpse stench gushed out, making people sick.

Smelling this smell, Yang Qiuchi could be sure that the corpse in the coffin had at least not completely decomposed. A corpse without decomposition is obviously much more informative than a white bone.

After a while, the smell was not so strong, Yang Qiuchi put on special autopsy gloves, first arrived in front of the coffin of the Void Lingzi, carefully uncovered the quilt covering the surface of the corpse, and looked at it, and was happy in his heart, the skin on the corpse's face had not yet appeared The terrible scene of the [***] giant view, which means that the corpse is only in the beginning [***] stage, in this way, you can find more useful information.

Xulingzi died on the third day of the ninth month, when the weather had become cooler, and then it was a cold winter, because it was a concubine, there was no problem of a big marriage, so it was quickly buried in the ground, which greatly slowed down the progress of the corpse [***], so, although half a year passed, the corpse was only the beginning [***].

Xu Lingzi was wearing a new dress, and after asking Xue Lu, he learned that the dress of the deceased when he was killed had been changed and burned, which made Yang Qiuchi very sorry, because sometimes the victim's dress can also provide a lot of useful information for finding clues to the murderer.

Yang Qiuchi untied the skirt of the Void Spirit, and sure enough, there was a knife on the left chest and heart, with a double acute angle, and the probe had pierced the heart, which was a fatal injury. Examination of other parts of the body revealed no abnormalities except for the dislocated jaw.

After asking Xue Lu, he learned that the corpse had been thoroughly cleaned before being buried, including [***]. Yang Qiuchi was very frustrated when he heard the news, so that no useful physical evidence such as saliva spots, semen or epithelial cells could be extracted from the corpse.

Yang Qiuchi asked Song Yun'er to help put on the corpse's clothes, and then came to the coffins of the two maids by himself to conduct an autopsy.

Both maids were only fifteen or sixteen years old, and the cause of death was clear, both were fatal stabs in the neck, which almost cut off the entire neck. The murderer was very vicious and cruel.

The corpses of these two maids[***] were lighter than those of the Void Spirit, which was related to the cause of their deaths.

The human body is the process of decomposition of tissue proteins in the body due to the action of bacteria, if the environment or human body conditions are conducive to the reproduction of bacteria, the speed will be very fast, otherwise it will slow down. After death, the bacteria that originally parasitized the human mouth, respiratory tract and gastrointestinal tract will enter the blood vessels and lymphatic vessels and multiply in large numbers, decomposing and destroying human tissue proteins.

However, if the deceased dies of sudden hemorrhage, on the one hand, it will inhibit the growth of [***] bacteria by losing a large amount of water required for the reproduction of [***] bacteria, and on the other hand, after a large amount of blood is lost, it will also block the path and speed of [***] bacteria spreading throughout the body, resulting in [***] slowing down.

These two maids were both neck cuts, causing sudden hemorrhage in the body, so the [***] degree of the two of them was lighter than that of the Void Lingzi. This provides a good condition for observing the wound.

The incision wall of the maid's neck is smooth, and it must be a sharp cut.

Yang Qiuchi buried his head in the coffin, and carefully observed the wound wall little by little, and the observation of the wound wall was conducive to determining the characteristics of the murder weapon.

Sure enough, the hard work paid off, and Yang Qiuchi soon found that something was wrong with this incision, but he didn't know what was wrong.

Yang Qiuchi first asked Song Yuner and the others to retreat into the distance, and then took out a magnifying glass from the forensic physical evidence investigation box, pushed the deceased's head to the side, and better exposed the incision, and then carefully observed the neck incision with a magnifying glass, observing the past inch by inch, and finally, on the smooth wound wall, a relatively rough line with the width of a grain of rice was found, from top to bottom, if you were not careful, you couldn't see it at all.

Is it caused by [***]? Yang Qiuchi was not sure, so he hurriedly ran to another maid and carefully examined the neck wound of the maid ring, and there was also such a rough line-like trace.

Song Yun'er looked at Yang Qiuchi and ran around with something in her hand to check, a little strange, and couldn't help but ask from afar: "Hey~!" Brother, what's wrong? Is there something wrong? ”

Yang Qiuchi put the magnifying glass back in the investigation box, beckoned to Song Yun'er to come over, and said, "Didn't we say that you would be responsible for arresting the murderer in this case?" Yang Qiuchi pointed to the incision on his neck and said to Song Yun'er: "You take a closer look and see if there is anything wrong?" ”

Song Yun'er lowered her head and looked at it for a long time: "Judging from the cut surface of the skin layer of the neck and the cervical vertebrae, it should be a sharp cut, and it was only cut once, almost cutting off the neck, the knife is very fast, and the force is very fierce." ”

Song Yun'er has followed Yang Qiuchi for so long, and she has learned many professional terms, plus she is strong in martial arts, and she has a good understanding of the wounds formed by this kind of cut, so she is right.

Yang Qiuchi nodded: "Take a closer look, is there anything else?" After a pause, seeing Song Yun'er's dazed face, she deliberately pointed to the wound wall, especially the relatively rough place. Song Yun'er bent down and almost put her nose on the incision, but still didn't find anything.

It is no wonder that if this difference is only observed with the naked eye, it will not be visible at all, Yang Qiuchi also relied on years of experience to accumulate and felt the difference from the normal sharp wound, which was determined through a magnifying glass. Although Song Yun'er has a keen eye, after all, she has not undergone professional training in this area, and she lacks knowledge in this area, so she naturally can't see it.

Yang Qiuchi pointed to the rougher mark the size of a grain of rice and said, "This part of this incision is not quite the same as the marks on other parts, can you see it?" ”

Yang Qiuchi pointed out the different lines with a probe, and now Song Yun'er noticed it and nodded: "It's different." ”

"How is it different?"

"Like...... It doesn't seem to be that smooth...... It's a bit rough. ”

"Exactly!" Yang Qiuchi said with a smile, "My Yun'er's eyes are more effective than a magnifying glass. ”

"Magnifier? What magnifying glass? ”

"That's it...... It's just to open your eyes wide, and some people can't see it even if they open it wide. Hey hey"

Song Yun'er was a little proud: "People who practice martial arts, it's not okay if your eyes are not good, you can't see clearly and can't see accurately, then it's all over." ”

Yang Qiuchi said: "Now you check the three corpses and see if you can find clues to solve the case." ”

"Okay!" Song Yun'er excitedly agreed, and looked carefully at the bodies one by one, and in the end, her excited eyes darkened, and she shook her head: "Except for this clue that may be Ji Gang's Jinyi Weigan, I can't find any other clues-even if this clue, if you don't tell me, I don't know." I'm so stupid! ”

Yang Qiuchi patted her on the shoulder: "You can't say that, after all, you don't specialize in this business." ”

Song Yun'er pouted: "Then you are not, you used to be just a junior apprentice, and besides, your master's ability can't be compared with you, how do you know so much?" ”

Yang Qiuchi smiled and pointed to his head: "Think here, think about it, think about it." ”

"Humph! You're going to tease me! ”

Yang Qiuchi put his arm around her waist and said, "I can give you a little hint, you should be able to find clues, and if you test more in the future, you will be able to do it slowly." ”

Song Yun'er nodded happily.

"The wall of the cut with a sharp object is very smooth, you know that." Yang Qiuchi let go of her small waist and pointed to the rough lines of the neck incision of the corpse in the coffin with a probe: "But the whole place where the wound is cut is not very smooth, and it is a little rough, a bit similar to ......"

"Tear Wound!" Song Yun'er exclaimed excitedly, "I know, the murderer's machete has a gap!" ”

Yang Qiuchi looked at her with wide eyes: "Look, you still say that you are stupid, I just said the beginning, and you can guess it." ”

Song Yun'er was a little proud again: "This person has been dead for a long time, if it was a fresh wound, I should have been able to see it a long time ago." ”

"Well, then you can talk about your detection ideas based on this discovery!"

Song Yun'er pondered for a while and said: "Judging from the traces, the gap on the murderer's single knife is the size of a grain of rice, as far as the knife is concerned, it should be regarded as a big gap, since we have locked the suspect within the scope of Ji Gang's Jinyiwei, then let's investigate according to two clues, one is the Jinyiwei who suffered from Hualiu disease around the third day of September last year, and the other is the Jinyiwei who used the embroidered spring knife with a large gap in rice grains." Right? ”

Yang Qiuchi nodded: "That's right, however, the second clue can't be used as the main detection direction at present." ”

"Why?" Song Yun'er said curiously.

"There are tens of thousands of Jinyi guards in the capital, do we want a knife to check the past?" Yang Qiuchi smiled, "Besides, although the murderer is almost certainly Ji Gang's Jinyiwei, but the murderer does not necessarily use the embroidered spring knife to assassinate him, if he uses another knife, even if we check all the more than 10,000 embroidered spring knives of the Jinyi Guard in the capital, we can't find this person." ”

"Hee-hee, that's right. So this clue is basically useless? ”

"That's not the same thing," Yang Qiuchi said, "at least, this feature can be used in the future when we find the suspect and make a determination." At the same time, Jin Yiwei, who suffers from flower willow disease and has a gap in the knife, can basically be determined to be the murderer. ”

"Well, however, there is a gap the size of a grain of rice on the blade, and this knife is generally costly, and there is no value in polishing, so it usually has to be forged again."

Yang Qiuchi's heart moved: "Yes, the issuance, recycling, repair and replacement of Jinyiwei's embroidered spring knife are all managed by the Jinyiwei armory, if the murderer uses the embroidered spring knife, and this knife can no longer be used because of the gap, then the Jinyiwei's armory must have a replacement registration, check the replacement record in September, maybe there will be a discovery!" ”

The two found another clue, and they were both very happy.

Next, Yang Qiuchi took a blood sample from the deceased. After the autopsy was completed, Xue Lu stepped forward to inquire about the inspection situation, Yang Qiuchi was not good at talking to him in detail, only said that he had found some clues and would continue to follow up.

Back at Yang's Mansion, Yang Qiuchi first went to his study to inspect the dagger.

His original study was cheating in because Lu Huanji, who was married by the emperor, and Yang Qiuchi felt bad luck and ordered it to be demolished and rebuilt. And built according to their own ideas, so that the solar battery they put on the roof is well hidden, and their own large aluminum alloy cabinet is also well hidden.

Yang Qiuchi took out the dagger and carefully inspected the handle of the rope with a magnifying glass, and found no blood fingerprints, presumably, after the murderer stabbed that knife, he let go of his hand before the blood splashed on the palm, or simply flew out of the dagger at a certain distance and stabbed the deceased in the heart.

In this way, it is impossible to leave a bloody handprint on the dagger. The only thing left is to look for colorless sweat stains.

Yang Qiuchi carefully brushed the handle of the knife with a magnetic fingerprint brush and extracted a few mutilated fingerprints. Yang Qiuchi was very happy. It was compared with the fingerprints of the people who had participated in the on-site investigation and had been taken from the yamen.

After the comparison, Yang Qiuchi was dumbfounded, and several mutilated fingerprints on the handle of the knife were all left by the arresters who participated in the on-site investigation at that time.

Could it be that the murderer did not leave fingerprints on the hilt of the knife?

The things that people have touched do not of course leave fingerprints, whether they can leave fingerprints, or whether they can leave fingerprints that can be found and extracted by prior art, are affected by many factors, the most important is the special surname of the object itself that is touched, and then the sweat stains on the hands of the perpetrator, of course, there are also extraction methods and technical factors. There are too many factors that affect fingerprint extraction, and it is common for fingerprints not to be extracted.

Of course, there is also the case where the killer used a tool such as gloves to block the fingerprints. What exactly is the reason is unknown, anyway, it is a fact that the fingerprints of the murderer were not taken.

Yang Qiuchi extracted the blood sample on the knife, which matched the blood sample of the deceased, both of which were type B, and the previous analysis of the sperm spots showed that the murderer was type A blood, indicating that there was no blood of the murderer on the knife.

This may seem redundant, but it is not, if other blood types are found on the knife, it will be an important clue, and the criminal investigation is to find clues as much as possible and find suspects according to the clues. Therefore, the forensic examination stipulates that there are routine testing items to prevent the omission of important clues, and some of these tests, which may seem useless according to the circumstances of the case, must not be omitted, because no one knows which cloud has rain. Important clues to solve the case are often hidden inadvertently.

In the evening, Ma Du and Niu Dahai took a thick notebook and came to Yang's mansion.

Ma Du bowed and said: "My lord, the humble and Niu Qianhu took people to all the Jinyi Weilang in the capital to conduct a detailed investigation, questioned all the Jinyi Weilang, and checked the corresponding treatment registration. It was determined that a total of 127 people had been treated at Jinyi Weilang for Hualiu disease in the first two months of last year, and the lowly post had already taken the diagnosis and treatment register and prescriptions issued at that time. ”

Depend on! Yang Qiuchi secretly cursed, so many Jinyi guards suffer from flower willow disease, what a bunch of perverts and hungry wolves! Because the Ming Dynasty's prostitution was openly legalized, and it was also legal to sell silver and scoop prostitution, and if you have this disease, you will not be as taboo as modern times, and you will not hide it and be embarrassed to go to the doctor, so this data should be accurate, which provides a good help for the investigation of the case.

But how to check these more than 100 people?
