The first deceased, Fan Xiaohong, sang in the Swallow Building, and the second male deceased, Sun Gang, met the prostitute Tang Jia in the same Swallow Building, and then Fan Xiaohong and Sun Gang were killed in the same form one after another, and Tang Jia disappeared inexplicably, and it is not possible to say whether it was killed or other reasons for the time being. However, the identities of the three people seem to tell us that the targets of the murderers are selective and targeted.

If the carriage that appeared in both cases was the same one, the owner of the carriage should be suspected of committing the crime. Tang Jia, as the young lady of Yanzilou, must have had some contact with Fan Xiaohong, and Sun Gang was killed when he went to an appointment with her that night, so she should or may be a co-defendant.

Based on the results of the on-site inquests in the two cases, it was initially inferred that the crime was committed by a gang and the motive was to rob property. If nothing else, as long as you find Tang Jia along the way, the problem can be solved.

During the visit, according to the relevant contacts, Tang Jia's residence was found. As soon as we entered the house, we smelled a faint stench. Walking quickly to the master bedroom, I saw a young woman lying naked on her back on the bed, with a Tibetan knife stuck deep in her lower abdomen, and the oozing blood stained the sheets red, flowing to the ground, forming a large pool of coagulated blood.

Identified by acquaintances, the female deceased was the Tang Jia we were looking for.

After Xiao Yu'er's preliminary autopsy diagnosis, Tang Jia's cause of death was hemorrhagic shock caused by a ruptured spleen; Numerous human dental imprints on the body surface such as lips, cheeks, breasts, and inner thighs, accompanied by congestive purple finger marks; There are coagulated sperm spots on the vulva, indicating that Tang Jia had had more intense sexual acts before his death.

The Tibetan knife is a collection on the bookshelf of Tang Jia's house, and it should have been randomly picked up by the murderer to commit the crime. Xiao Yu'er extracted a clear fingerprint from the handle of the hidden knife.

There were large traces of turning at the scene, the interior drawers and cabinet doors were opened, and the belongings were looted. Tang Jia's fingers and neck were left with old ornament indentations and drag marks, indicating that the gold and silver pendants he carried with him were also robbed.

Combined with the indoor temperature and humidity, looking at the formation of corpse spots and the decomposition process, Xiao Yu'er deduced that Tang Jia's death time should be in the early morning of July 15-16. It is very close to the time of Sun Gang's death.

The body was pulled back to the yamen and passed through Mr. Guò Gongsun for a detailed autopsy. Several things were found at the scene of the crime, and after Sun Gang's verification, some of them did not belong to Sun Gang. It belongs to another man.

In the subsequent analysis of the case, I determined that Tang Jia and the coachman must be the murderers in the two cases. Tang Jia was familiar with Fan Xiaohong and Sun Gang, and after learning the whereabouts of the two, he sued the coachman and killed the two deceased when they took a taxi. As for Tang Jia's murder. It seems to be understood that the driver has decided to stop doing it, worried that Tang Jia will leak the news.

Bao Heizi immediately denied it. If Tang Jia and the coachman jointly planned such a vicious serial murder case, the relationship between them must be very strong, but it is unreasonable to kill their companions just to prevent the risk of potential leakage of information after robbing such a small amount of property. What's more, the coachman should have thought that the government could find him based on Tang Jia's interpersonal relationships, so it was impossible for him to rape Tang Jia and leave physical evidence. And the room full of fingerprints.

There is some truth in Bao Heizi's analysis, but I immediately refuted him: if the murderer was really thoughtful, even to the point of extreme, there is a high probability that he would have anticipated the potential risks after committing the crime. In other words, the murderer has a subjective consciousness of infinitely magnifying the risk after committing the crime. So, even if the amount of robbery is small, but for your own safety. He also had a reason to poison his close companions. In addition, since Tang Jia is a foreigner, it is possible that her companion is also a foreigner. After the murder. It's completely possible to escape from Duanzhou, so we have nowhere to look. Also, since the two have a very close relationship, Tang Jia should have some items of the murderer left in his room. Therefore, his so-called robbery is actually to create the illusion of robbery, rape and murder, and more importantly, he wants to take away all the items that belong to him in Tang Jia's house.

Bao Heizi thought for a while and said, "It still doesn't seem right." If I were a coachman, the first thing I did after I sent Sun Gang to Tang Jia's house was to immediately arrest him, why did I have to wait until Sun Gang had sex with Tang Jia before killing anyone? ”

Questions about the murderer's motive and how he carried it out have been debated for a long time. In the end, Xiao Yu'er said: "It's all about guessing and reasoning, and now we have to start with what we can see." Everyone noticed that Fan Xiaohong and Sun Gang were both trapped with ropes after their deaths, what was the purpose of the murderer's act of kidnapping corpses? If the murderer is indeed male, does he have a special preference, so he took this relatively rare binding behavior against Fan Xiaohong. But tying up Sun Gang seems a little unreasonable. Could it be that he is bisexual? In addition, assuming that Tang Jia was an accomplice to the murderer, that is, the so-called inside line and bait, the murderer also expected that her storage would be discovered by the government, so he created a false scene. So, why didn't the murderer take the criminal methods of the first two cases and tie up Tang Jia and kill him? In this way, the government's sight can be confused to the greatest extent, so that we cannot guess that he had conspired with Tang Jia. ”

After a pause, Xiao Yu'er said again: "It's still hypothetical." Assuming that the coachman is indeed the first murderer in this case, and that Tang Jia is indeed the inside line and bait in this case. Tang Jia naturally knew Sun Gang's movements, so he informed the coachman to wait outside the inn, and then dragged Sun Gang to his home. But the question is, since the two are conspiring with the purpose of murder and robbery, the coachman will definitely have the room key, how good it is for him to hide in the room, or lurk outside the door and wait for the opportunity to commit the crime, why do you have to blatantly go to Wangjiang Tower to wait for Sun Gang, and personally drag him to his destination. Also, how could the murderer be so sure that Sun Gang would ride in his own vehicle. You must know that there are a lot of vehicles in front of the hotel, and if Sun Gang did not take his car, but drove himself or took another car, the murderer's waiting behavior would have completely lost its meaning. ”

Hearing this, I immediately said: "Even if Sun Gang took the murderer's carriage a little unreasonable, Fan Xiaohong did disappear and was killed after sitting in the same type of carriage, is this just a coincidence?" I think the chances of the driver being the murderer are still the highest. ”

Xiao Yuer said: "Tang Jia and Fan Xiaohong are both escort girls, and the two may know each other, but they may not know that Fan Xiaohong will 4P with others after work on the night of the crime, let alone know exactly the end time." Then why did the coachman appear downstairs outside Fan Yuan on time, could it be that after Tang Jia instructed and memorized Fan Xiaohong's appearance, he kept following and was always ready. Preparing to commit murder after Fan Xiaohong gets in the car? Isn't that ridiculous? Since Tang Jia knows Fan Xiaohong, he should be familiar with his normal whereabouts and trajectory, and he can find a relatively relaxed time period to commit murder, is it necessary to choose the day of 4P? Even the coachman and Tang Jia couldn't wait, and they scratched their palms without committing the crime, and Tang Jia also estimated the time of premature ejaculation outside the fan, and asked the coachman to wait downstairs. But have you thought of it, Fan Xiaohong is a female student, she goes to other people's 4P at night to adjust the relationship between husband and wife, how much money can she bring with her, and she is not the Sun Gang who opened a repair factory. The murderer just took great pains to follow and wait for this money, which is completely unreasonable. (To be continued......)
