The other deceased was a middle-aged woman, leaning against the wall inside the kang, her hair was gray, her eyes were slightly closed, her face and neck were full of wrinkles, her skin was gray and rough, a pair of shriveled and flabby ** drooped on her chest, and there was also a wound similar to the wound on Tu Laosi's body at the mouth of her heart, and the blood that flowed out formed a pool of blood where she was sitting.

Yang Qiuchi carefully measured the two knife wounds, and the wounds were about the same shape and depth, most likely formed after being stabbed with the same knife.

Judging from the location of the corpse spots on the two corpses, which are located in the low position of the corpses, which is consistent with the posture of the body, plus a large pool of blood on the bed and on the ground, Yang Qiuchi judged that this was the first scene of the crime.

Judging from the fact that the two deceased were stabbed in the heart and died of hemorrhagic shock, the murderer shot accurately and did not stab the second time, which shows that he was very confident in his assassination skills and the results caused. Judging from the fact that there were no resistance injuries on the two deceased, it shows that the deceased had no chance to resist at all, and was killed with a knife, which further shows that the murderer is sophisticated and calm.

Of course, there is also a possibility, that is, the deceased is familiar with the murderer, and he didn't expect the murderer to kill, so he didn't resist, but this possibility is almost non-existent, because this Tu Laosi came to the scoop prostitute, as the saying goes, "single scoop double gamble", most of the scoop prostitutes practice alone, and generally do not go in groups, so it is unlikely that the murderer came to find Xu's scoop with Tu Laosi. More importantly, judging from the fact that the latch of the door was opened by a knife, it is unlikely that the murderer knew the deceased, otherwise he could have called for the door to open and kill people while they were unprepared.

The murderer's hand is the heart of the deceased, and the deceased is not clothed, and in the absence of obstruction, after being stabbed in the heart, blood will gush out, so the murderer's hands, sleeves and even the front of the clothes are likely to be splashed with blood spots, which can be proved from the wiping marks on the quilt.

Although there was a system of drawing fingerprints in ancient times, there was no professional technology such as fingerprint identification, and fingerprint comparison did not become a means of criminal investigation, nor could it be used as evidence for criminal offenses, so the killer did not hide the concept of his fingerprints, which left more bloody handprints and blood fingerprints at the scene. This gave Yang Qiuchi a reassurance. With these fingerprints, there is no problem in making the same identification of the suspect.

Next, it is necessary to judge the time of death, and if the time of death is determined, the time of the murderer can be determined, and the foundation for future investigation can be laid.

First to check the corpse spots, Yang Qiuchi lifted the quilt and found that Tu Laosi had stained green stains on the skin of his lower right abdomen, which was the result of hydrogen sulfide and hemoglobin in the intestinal tract forming sulfide hemoglobin after the death of the person, commonly known as corpse green, this corpse green will spread to the whole body with the further development of the corpse [***]. The appearance of corpse green indicates that the time of death should be between 24 and 36 hours.

In addition to this piece of corpse green, Yang Qiuchi also found long strip-like scars on Tu Laosi's thighs and pubic areas, some of which were already old, and some were very fresh, which should have just formed two or three days ago. Looking closely at these long strip scars, Yang Qiuchi was a little strange, this scar was obviously not a resistance injury, it seemed to be left by whipping with a leather whip, but the force of the whipping was not large, but the number of times was many, almost connected into a block, as if the person who carried out the whipping deliberately controlled the strength, so as to only cause the other party's pain. It's weird.

Yang Qiuchi turned Tu Laosi's body over, and a large area of corpse spots had appeared on the back of the corpse, but the corpse spots were not obvious, which was due to the deceased's massive blood loss.

Although covered by corpse spots, Yang Qiuchi still distinguished the same whipping scars on the back of Tu Laosi's thighs, buttocks, and back of his thighs, most of which were old, and these long scars were dense and almost connected. It should be accumulated over a long period of time.

Yang Qiuchi carefully observed the corpse spots on the corpse, waited for a while, the corpse spots did not move down, and pressed the corpse spots with his fingers, the corpse spots did not fade, indicating that the corpse spots had entered the infiltration period. During this period, because the plasma stained with hemoglobin in the blood not only penetrates into the interstitial space, but also infiltrates the tissue cells, coloring the tissue cells, the corpse spots will not be transferred, and the acupressure will not fade. At this stage, the time of death is at least twenty-four hours.

Yang Qiuchi held Tu Laosi's jaw and moved, and then moved Tu Laosi's limbs, and found that the jaw mortis had begun to ease, which was consistent with the situation of the previous corpse spots, and the time of death should be twenty-four hours to forty-eight hours.

Turning Tu Laosi's eyelids, he found that his cornea was cloudy and connected to the lens, and the pupil was already difficult to see, which was due to the edema and autolysis of the deceased's cornea itself, which gradually turned into an opaque milky white, so that the pupils could not be seen through. The degree of corneal opacity is regular and can be used to determine the time of death. According to the degree of conjunctival opacity in Tu Lao's four eyes, Yang Qiuchi judged that the time of death was also between 24 and 48 hours.

Yang Qiuchi found a small stick, broke open the deceased's mouth, and scratched the deceased's mouth with the small stick, and found that the oral mucosa had autolyzed and peeled off. The speed of autolysis of corpses is related to climate and temperature, and it is winter, and this obvious autolysis of corpses appears, and Yang Qiuchi judged that the time of death was also more than twenty-four hours. This is consistent with the appearance of corpse spots.

Yang Qiuchi did not find the appearance of [***] venous network on Tu Laosi's body, the so-called [***] venous network, which is the blood vessel wall of the subcutaneous venous network because it is impregnated with hemolytic hemoglobin and is dark red, and it is dendritic through the skin. If this is the case with the corpse, it can be judged that the time of death should have been more than three days. Since Tu Laosi's body has not yet appeared in this case, the time of death will not exceed three days.

Yang Qiuchi examined Xu's body again, and the results were roughly the same except that there were no whipping wounds.

Based on the above examination, it is estimated that the deceased Tu Laosi should have been dead for 24 to 48 hours. Tu Laosi's parents said that Tu Laosi left home the morning before yesterday, and according to the neighbor's confirmation, the woman had borrowed rice from the neighbor the afternoon before yesterday, and the time of death was shortened, and the homicide should have occurred between the afternoon before yesterday and yesterday afternoon.

The bloody handprints left by the murderer on the quilt are to be extracted. Yang Qiuchi found a pair of scissors, cut off the few wiping marks and bloody handprints on the quilt and put them in his arms.

Next, it's time to survey the traces left on the ground at the site.

Yang Qiuchi squatted on the edge of the kang, first picked up the shoes of Tu Laosi and the female Xu Shi to carefully check the sole pattern and the length and width of the shoes, and then lay on the ground to observe the shallow and scattered footprints, and screened them according to the pattern and size.

After a long time, after excluding the shoe prints of Tu Laosi and Xu, I finally found a shoe print that was different from the shoe prints of the two deceased and relatively large. Referring to Tu Laosi's shoe prints, it can be judged that the two shoe prints were formed at about the same time, indicating that they may have been left by the murderer. In addition, no other suspicious shoe prints were found, and it seems that there are indeed not many customers of this female Xu, and there are few people at home.

Judging by the shoe prints and the same wounds on the two deceased, there should have been only one murderer who entered the scene.

I found a ruler to measure the shoe prints, and according to the calculation formula, height = foot length× 6.876, it was estimated that the height of this person should be about 1.8 meters.

Yang Qiuchi looked closely at the shoe print, and at the heel, Yang Qiuchi found a small black particle about the size of the needle's buttocks.

The room was a rammed loess surface, relatively flat, and no similar black particles were found elsewhere on the floor of the room, indicating that the soles of the murderer's shoes were probably falling off. Yang Qiuchi found a piece of white paper, carefully extracted the black particles, wrapped them in white paper and put them in his arms.

Yang Qiuchi found the ink and white paper, took the fingerprints and palm prints of Tu Laosi and Xu, folded them and put them in his arms.

The clothes of the two deceased were placed on the chairs on the side, and after Yang Qiuchi searched carefully, he found a money bag in the pocket of Tu Laosi's clothes, and opened it carefully to see that there were four ingots of silver in it, estimated to be more than thirty taels.

Yang Qiuchi is very strange, yesterday they went to Tu Laosi's house, his family was poor, and then looked at Tu Laosi's clothes were old and torn, and they came to find this kind of retired girl with gray hair, this Tu Laosi's life should be more difficult, why do you have so much silver on your body? There must be something wrong with the origin of this silver, so Yang Qiuchi decided to take it back and study it carefully to see if he could find something on it.

Judging from the discovery of these silvers and the fact that there were no traces of turning at the scene, after the murderer killed, he did not look for property, indicating that the murderer did not come for money, but should be a vendetta or murder - this old man is old, ugly and has no money, and this female Xu is also an old man, and the door is full of birds, so love killing can basically be ruled out.

Everything was done, it was almost dusk, and after the inspection, Yang Qiuchi went out of the room. Governor Zhou and the others hurriedly greeted them. Fill in the corpse compartment.

Yang Qiuchi said: "After examination, the deceased Tu Laosi and Xu Shi were both stabbed into the heart with sharp objects, causing massive bleeding and died. The murder weapon was a single-edged dagger with a blade length of not less than six inches and a width of 0.9 inches. The murderer is about five feet four inches tall, from the analysis of the scene, there is only one murderer who entered the scene, the crime is calm and calm, the methods are cruel, the two deceased were killed with a knife, indicating that the murderer is good at this, is a veteran, and may have committed crimes before. ”

Zhou Zhifu, Song Zhixian, Song Yun'er and others listened with straight eyes, Yang Qiuchi found so many clues based on such messy things, this case is about to come out, it is really admirable.

Governor Zhou asked: "Does Yang Gongzi have a specific direction for solving this case?" ”

"The time of death of the deceased should have been between the afternoon before yesterday and yesterday afternoon." Yang Qiuchi took out the money bag from his arms, "I found this money bag in the pocket of Tu Laosi's clothes, there are about thirty taels of silver in it, I suspect that this silver is related to the case, I want to take it back for observation and analysis, and return the silver back to the prefect's yamen in two days." I don't know if it's possible? ”

Governor Zhou nodded in agreement, he really wanted to ask what problems could be found from this silver, but he didn't understand this kind of thing, so it was best not to ask more, so as not to make people laugh.

Yang Qiuchi said: "According to Liu Biao's testimony, the IOU found at the scene of Jin Keying's burial is likely to be left by Tu Laosi, and these neighbors have all proved that Tu Laosi is left-handed, which is consistent with the scars of Jin Keying's body, and now he was suddenly killed, it is likely that he was killed, so Tu Laosi is likely to be the murderer who killed Jin Keying." In this way, there should be a culprit behind the scenes. ”

Song Zhixian asked, "Then, who is the culprit?" ”

Yang Qiuchi smiled bitterly, do you really think of me as an immortal? Shaking his head: "It's not clear. Now let's go to Tu Laosi's house to search and see if we can find any clues. ”

Zhou Zhifu and Song Zhixian nodded in agreement, and the aftermath of the corpse here was handed over to the evil for disposal, and they rushed to Tu Laosi's house with the catchers. Tu Laosi's house was very simple, there were no big furniture, and they searched all over after a while.

Yang Qiuchi found something in the cabinet in Tu Laosi's bedroom, looked at it carefully for a long time, and felt very strange, so he found a piece of cloth to wrap this thing, and after obtaining the consent of Zhou Zhifu, he put it in his arms and prepared to take it back for analysis.

After the search was completed, Governor Zhou's Mansion was supposed to hold a banquet to entertain Yang Qiuchi and them, but Yang Qiuchi refused, he was worried about the analysis of this physical evidence, as well as Hao Qian's matter, and he needed to make Song Qing clear immediately, and find a way to get Song Qing to withdraw from the marriage, whether it was Song Qing or Hao Qian, he had to discuss it with Yang Mu and Feng Xiaoxue before he could decide.

After hurriedly eating something, Yang Qiuchi and the others rushed to Guangde County.

On the way, Yang Qiuchi took his beloved little black dog and Song Qing in a carriage. Song Yun'er pretended not to see it and hid in her father Song Zhixian's carriage.

On the way, Yang Qiuchi briefly told Song Qing about the experience of going to Hao's house, told Song Qing that Hao's family wanted to make Hao Qian a concubine to himself, and asked Song Qing what to do.

Song Qing said: "Brother Qiuchi, I want to know, are you willing to marry me?" Song Qing also understood that if she quit the marriage, the Hao family would never let Hao Qian marry Yang Qiuchi, so only one person between herself and Hao Qian could become Yang Qiuchi's concubine, "Of course I am willing~!" Yang Qiuchi gave Song Qing a deep kiss, "If I didn't want to, I would have promised the Hao family a long time ago." ”

Song Qing smiled and said, "Don't you pity the eldest lady of the Hao family?" She is a famous beauty in Ningguo Mansion! ”

Speaking of Hao Qian, Yang Qiuchi immediately thought of the beautiful and seductive Danfeng eyes, as well as the unique temperament on his body, and he couldn't help but feel a little regretful in his heart, but principle is principle, although Hao Qian is very beautiful, more beautiful than Song Qing and all the girls he knows and has a temperament, but feelings cannot be exchanged, just like Bai Qian always wanted to exchange Bai Sumei for Feng Xiaoxue, it is absolutely unacceptable.
