The other deceased was a middle-aged woman leaning against the wall inside the kang. Her hair was gray and her eyes were slightly closed. Her face and neck were covered with wrinkles, her skin was gray and black and rough. Her pair of shriveled breasts were hung on her chest. There was also a wound similar to the wound on Tu Laosi's body at her heart. The blood flowed out formed a pool of blood in the place where she sat.

Yang Qiuchi carefully measured the wounds in the two places. The shape and depth of the wounds were similar, and it was probably formed after stabbing the same knife.

Judging from the location of the corpse spots on the bodies of these two corpses, they are located at the low position of the corpse, which is consistent with the posture of the body. In addition, there are 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 death of hemorrhagic shock caused by both deaths of the deceased by the heart, the murderer took the accurate action and did not stab the second time. It can be seen that he is very confident in his assassination skills and the results. From this, it is judged that this person is likely to be a professional killer or an experienced person who uses cold weapons to assassinate, or a criminal case, and is unlikely to be a novice. Judging from the fact that neither of the deceased has the opportunity to resist, and is killed by a knife, which further shows that the murderer's sophistication and calmness is not likely to be a novice.

Of course, there is another possibility, that is, the deceased is familiar with the murderer, but he did not expect the murderer to kill people, so he did not resist. However, this possibility almost does not exist, because the Tu Laosi came to visit prostitutes. As the saying goes, "single prostitution and double gamble". Most prostitution practices alone and generally does not go in groups, so the murderer is unlikely to come to Xu's family to have sex with Tu Laosi. More importantly, from the point of view that the door bolt was pushed away by a knife, it is unlikely that the murderer knew the deceased, otherwise it could be called to open the door and kill people while the person was not prepared.

The murderer's attack was the heart of the deceased, and the deceased was not wearing clothes. Without blocking it, blood would gush out after the heart was cut, so the murderer's hands, sleeves and even the front of the clothes were likely to splash blood spots. This can be proved by the wipe marks on the quilt.

Although there was a system of fingerprints and fingerprints in ancient times, there was no professional technology such as fingerprint identification. Fingerprint comparison did not become a means of criminal investigation, nor could it be used as evidence of criminal crimes. Therefore, the killer did not hide his concept of fingerprints, so he left more bloody handprints and blood fingerprints on the scene. This gave Yang Qiuchi a reassurance. With these fingerprints, there would be no problem to make the same identification of the suspect.

Next, we need to judge the time of death and determine the time of death, so that the murderer can be determined and lay a solid foundation for future investigations.

First, we need to check the corpse spots. Yang Qiuchi lifted the quilt and found that there were dirt green spots on the skin of Tu Laosi’s right lower abdomen. This is the result of the hydrogen sulfide and hemoglobin in the intestine forming hemoglobin sulfide, commonly known as corpse green. This corpse green will spread to the whole body as the corpse decay develops further. The appearance of corpse green indicates that the death time should be 24 to 36 hours.

In addition to this piece of corpse green, Yang Qiuchi also found long strips of scars on the thighs and vagina of Lao Si. Some of the scars were old and some were very fresh. They should have just formed two or three days ago. After careful observation of these long strips, Yang Qiuchi was a little strange. The scars were obviously not against the wound. It seemed that they were left with a whip, but the force of the whip was not large, but the number of times was very large, almost connected into blocks, as if the person who was whipping deliberately controlled the strength to only cause pain to the other party. It was really strange.

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

Although covered by corpse spots, Yang Qiuchi still identified the same whipping scars as Tu Laosi's thighs, buttocks and backs of his thighs. Most of them were old. These long scars were densely packed and almost connected into one piece. They should have been accumulated over a long period of time.

Yang Qiuchi carefully observed the corpse spots on the corpse. After waiting for a while, the corpse spots did not move downwards. He 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, since the plasma stained with hemoglobin in the blood not only intervenes in the tissue gaps but also infiltrates the tissue cells, the tissue cells will not be transferred at this time, and the acupressure will not fade. At this stage, the death time will be at least twenty-four hours.

Yang Qiuchi held Tu Laosi's jaw and moved it for a while, then moved Tu Laosi's limbs and found that the zombie zombie zombie had begun to ease, which coincided with the situation of the corpse spots in front. The death time should be 24 to 48 hours.

When he opened Tu Laosi's eyelids, he found that his cornea was turbid and connected to the crystals, and his pupils were difficult to see through. This was due to the edema and autolysis of the deceased's cornea, which gradually turned into opaque milky white, so that the pupil could not be seen through. The degree of corneal opacity is regular and can be used to judge the time of death. According to Tu Laosi's conjunctiva degree of conjunctiva, Yang Qiuchi judged that the time of death was also between 24 and 48 hours.

Yang Qiuchi found a small stick, opened the mouth of the deceased, and used the stick to scratch the deceased's mouth, and found that the oral mucosa had already self-soluble and shedding. The speed of the corpse's autolysis is related to the climate and temperature. It is winter, and the corpse has such obvious autolysis. Yang Qiuchi judged that the death time was also more than 24 hours. This is consistent with the appearance of the corpse spots.

Yang Qiuchi did not find any corrupt venous networks on Tu Laosi's body. The so-called corrupt venous network is that the blood vessel wall of the subcutaneous venous network is dark red due to being stained with hemoglobin and is branched through the skin. If this happens to the corpse, it can be judged that the death time should have been more than three days. Since Tu Laosi's body has not yet occurred, the death time will not exceed three days.

Yang Qiuchi checked Xu's body again, except for the absence of whipping scars, the other results were roughly the same.

Based on the above inspection, 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, so the death time was shortened. The murder should have occurred between the afternoon before yesterday and the afternoon yesterday.

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

Next, we need to investigate the traces left on the ground on the site.

Yang Qiuchi squatted beside the kang, first picked up Tu Laosi and prostitute Xu's shoes to carefully check the sole pattern and the length and width of the shoes. Then he lay on the ground to observe the few shallow and messy footprints, and distinguished them according to the patterns and sizes.

After a long time of hard work, after eliminating the shoe prints of Tu Laosi and Xu, I finally found a shoe print with different patterns and relatively large size. Referring to the shoe prints of Tu Laosi, it can be judged that the two shoe prints were formed at about the same time. It means that it may be left by the murderer. In addition, no other suspicious shoe prints were found. It seems that the prostitute Xu had not many customers and few people came to the family.

Judging from the shoe prints and the wounds on the two dead, there should be only one murderer on the scene.

I found a ruler to measure the shoe prints. Based on the calculation formula, the height of this person should be about 1.8 meters tall.

Yang Qiuchi carefully observed the shoe print. On the heel, Yang Qiuchi found a small black particle about the size of a needle butt.

The room is covered with a rammed yellow earth ground, which is relatively flat, and is located in other parts of the room ground. No similar black particles were found, which means that the soles of the murderer's shoes were 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 ink and white paper. He took the fingerprints and palm lines of Tu Laosi and Xu, folded them and put them in his arms.

The two deceased lay clothes on the chair next to them. After Yang Qiuchi searched carefully, he found a purse in the pocket of Tu Laosi's clothing. He opened it carefully and saw that there were four ingots of silver inside, which was probably more than thirty taels.

Yang Qiuchi was very strange. They had been to Tu Laosi's family yesterday, and his family was very poor. Seeing Tu Laosi's clothes were old and torn, they came to find such retired prostitutes with gray hair. Tu Laosi's life should be relatively difficult. Why do they have so much money on them? There must be a problem with the origin of this money. 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 lack of traces of flipping on the scene, the murderer did not look for property after killing people, which shows that the murderer did not come for money, but should have been a revenge or murder to silence people - this old man is old, ugly and poor, and this prostitute Xu is also a yellow man, and his family is deserted, so love killing can basically be ruled out.

After everything was done, it was almost dusk. After the inspection, Yang Qiuchi left the door. The magistrate Zhou and others hurriedly came up and filled in the corpse sheet.

Yang Qiuchi introduced: "After examination, the deceased Tu Laosi and Xu were both stabbed into the heart by someone with a sharp weapon, causing a lot of bleeding and died of death. The weapon was a single-edged dagger with a blade length of no less than six inches and a width of zero or nine inches. The murderer was about five feet and four inches tall. From the analysis on the scene, there was only one murderer who entered the scene. He was calm and calm in his crime and cruel in his methods. Both of the dead were killed by one knife, which shows that the murderer was skilled in this way and was a veteran. He may have committed crimes before."

The prefect Zhou, the prefect Song County, Song Yuner and others were all straightened. Yang Qiuchi found so many clues based on such messy things. The case was about to come out, which was really admirable.

Master Zhou asked: "Does Mr. Yang have a specific investigation direction for this case?"

"The deceased's death should be between the afternoon of the previous day and the afternoon of yesterday." Yang Qiuchi took out the purse from his arms, "I found this purse in Tu Laosi's pocket, which contained about thirty taels of silver. I suspect that the silver is related to the case. I want to take it back and observe and analyze it, and return the silver back to the prefect's office in two days. I wonder if it is possible?"

Master Zhou nodded in agreement. He wanted to ask what problems could be found from this money, but if you don’t understand how to solve such a thing, it’s best not to ask too much, so as not to make people laugh.

Yang Qiuchi said: "According to Liu Biao's testimony, the IOU found at the scene where Jin Keying buried the body is probably left behind by Tu Laosi. These neighbors have proved that Tu Laosi is a left-handed person, which coincides with the scars of Jin Keying's body. Now that he was suddenly killed, he may have been silenced. Therefore, Tu Laosi is likely to be the murderer who killed Jin Keying. From this point of view, there should be a culprit behind it."

County Magistrate Song asked, "Then, who is the culprit?"

Yang Qiuchi smiled bitterly, and he really regarded me as a god? He shook his head: "I don't know yet. Now let's go to Tu Laosi's family to search to see if we can find any clues."

The prefect Zhou and the prefect Song nodded in agreement. The body here was handed over to the offenders and led the constables to the fourth house of Tu Laosi. The fourth house of Tu Laosi was very simple and had no big furniture. They searched them all in a short while.

Yang Qiuchi found something in the vertical cabinet in Tu Lao Fourth's bedroom. After looking at it carefully for a long time, he found a piece of cloth to wrap the thing. After obtaining the consent of Master Zhou, he put it in his arms and prepared to take it back for analysis.

After the search was completed, the prefect Zhou originally wanted to host a banquet to entertain Yang Qiuchi and the others, but Yang Qiuchi refused. He was thinking about the analysis of the physical evidence and the matter of Hao Qian. He needed to explain it to Song Qing immediately and find a way to get Song Qing to break the engagement. Whether it is Song Qing or Hao Qian, he had to discuss it with Yang's mother and Feng Xiaoxue before he could decide.

After a hurry to eat something, Yang Qiuchi and 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 the carriage of her father, Magistrate Song.

On the way, Yang Qiuchi briefly told Song Qing about his journey to the Hao family, told Song Qing that the Hao family would grant Hao Qian to him as his concubine, and asked Song Qing what to do.

Song Qing said: "Brother Qiuchi, I want to know if you want to marry me?" Song Qing also understood that if she broke off the marriage, the Hao family would never let Hao Qian marry Yang Qiuchi. Therefore, there is only one person with Hao Qian who can become Yang Qiuchi's concubine.

"Of course I'm willing~!" Yang Qiuchi gave Song Qing a deep kiss, "If I didn't want to, I would have agreed to the Hao family long ago."

Song Qing giggled and said, "Do you have a pity for the eldest lady of the Hao family? She is a famous beauty in Ningguo Mansion!"

When talking about Hao Qian, Yang Qiuchi immediately thought of the beautiful and seductive Danfeng eyes and the unique temperament on his body. He couldn't help but feel a little regretful, but the principle is principle. Although Hao Qian is beautiful, she is more beautiful than Song Qing than all the girls she knows, and feelings cannot be exchanged. Just like when Bai Qian wanted to exchange Bai Sumei for Feng Xiaoxue, it was absolutely unacceptable.
