The investigation of Gong Xiaoxu has reached the final result, so has there been a breakthrough in the investigation of the interior of the wall of Room 107 of Building 1 in the Huayuan Community? The answer is yes.

The police determined that the wall behind the cupboard in Room 107 did indeed hide the body, which made the owner very shocked and angry, and after investigating the incident, Room 107 of Building 1 in the Huayuan Community was temporarily blocked by the police. The owner of the house was proved to be indeed innocent and did not participate in any details of the killing, and after actively cooperating with the police investigation, the owner immediately left S City, leaving Room 107 of Building 1 completely to the police to deal with.

For the old-fashioned cupboard that emitted a smell, fortunately, the police officer who came to investigate for the first time did not listen to Luo Yifan's stand-in Xiao Xuan's suggestion and rinsed the entire cupboard with water, so the fingerprints on it were completely retained, and the police carefully inspected every inch of the cupboard, and directly detected the fingerprints of Hong Huijian and Cheng Chu from above, and in the middle of the detailed inspection, the police actually got half a hair from a crack in the door of the cupboard, which is obviously a man's hair, very short, plus the cupboard is dark, If you are not careful, it is extremely easy to neglect the past.

This hair was immediately sent back to the police department, and it was quickly confirmed that it came from Wei Guigui's body, which is a very important piece of information, which can prove several things: first, Wei Guigui had touched the cupboard, and it is likely that the body and the cupboard were not put in the wall by Hong Huijian and Cheng Chu, but Wei Guigui.

Second, it can be proved that Wei Guigui did follow Hong Huijian, the owner of the house is abroad all the year round, and most of the time the rent is contacted by telephone, or entrusted to the intermediary company, and rarely he is personally present, which has been confirmed from both the owner and the intermediary company. If Wei Guigui had been secretly following Hong Huijian, he would definitely know where Hong Huijian rented a house, and it was not impossible to use the blank time between viewing and moving in to pretend to be a courier to secretly send a few pieces of old-fashioned furniture to the house in the name of Hong Huijian, and then hide the body in the wall.

Even if Hong Huijian later found out that the furniture was not his own and threw it away, it would not cause the body to be found by him, because the smell of the garbage transfer station can be used as a perfect reason for the smell in the house.

Third, the wall behind the cupboard has been repaired almost exactly like the original, which shows that it took a lot of effort, if it hadn't been for Yun Yeyao to break the wall and find that it was all made of broken bricks, he would not have found that the wall in this place had been dug up and repaired. In addition, mutilated fingerprints were found on the cement and broken bricks, which matched Wei Guigui, further proving the fact that Wei Guigui had been here before, and that he was the one who hid the body inside the wall.

Fourth, the cupboard is dirty, and after dismantling, it is covered with traces of cockroach feces, bed bugs, and even rat droppings, but not a single live bug or mouse has been found, which is the most strange. Judging by the filth of the cupboard, it is impossible not to have a live insect, and the partition of the cupboard has recently been disassembled, because the dirt in the joints has been scraped off a lot.

Through these two points, it can be fully proved that this cupboard was once placed with a large object, and this thing smelled of insects and rats that did not like it, causing them to 'withdraw' it from the cupboard after smelling it. The biggest possibility is that Wei Guigui used this cupboard to load the female corpse soaked in disinfectant water.

Fifth, it is the cloth on the sack found between the walls by Yun Yeyao, after testing, the cloth has traces of long-term contact with formalin, although formalin is particularly volatile, but it can still be detected by technical means, especially things that have been in contact for a long time. And on the side of the sack cloth, the police technicians also extracted a little bit of silk to seal the plastic bag.

These can prove that the body was wrapped in a sealed plastic bag containing formalin solution, and then put it into a sack, and it is possible that during the transportation or hiding process, the sealed plastic bag was punctured a little bit, causing the formalin solution to overflow and contaminate the sack and the gap between the wall, which is why Yun Yeyao will smell a strong pungent smell after breaking through the wall.

All of the above is enough to prove the fact that Wei Guigui killed and hid the mysterious female corpse in Hong Huijian's rented place.

According to the police investigation, Tong Lili was only admitted to Room 107, Building 1, Huayuan Community, on May 5, before April 30, Hong Huijian had checked out, from April 30 to May 2, Hong Huijian and Cheng Chu did not return to Huayuan Community, Wei Guigui had enough opportunity to go to Huayuan Community to secretly take away the body before going up the mountain on May 2, and hide it in the trunk of a Volkswagen.

It is an indisputable fact that Wei Guigui wants to replace Jiang Xiaomei with a female corpse, in this regard, Mo Haiyou and Yun Yeyao's reasoning is very consistent: First of all, Wei Guigui is to blame Hong Huijian for the fact that the female corpse was killed, anyway, Hong Huijian will kill many people in the future, and there is no shortage of charges brought by such a corpse, and it is safest to blame Hong Huijian. Secondly, another reason why he took great pains to bring the corpse was that Wei Guigui could not know the secret room inside the Luoque House like Hong Huijian, so he had no way to hide the corpse in the Luoque House in advance.

And why Wei Guigui killed the mysterious woman half a month ago, the only explanation for this is that it is possible that he does not have full control over the time to kill this woman. In the course of the investigation of Wei Guigui's surrounding relatives and friends, among the people he knew, there was no woman who suddenly disappeared, that is, the identity of this woman was the first, and she was a person who had nothing to do with Wei Guigui; second, certainly a celibate out-of-town woman, and very easily deceived; Third, it must be impossible for the place where she lives to be in the vicinity of Wei Guigui, and it is possible that Wei Guigui followed him for a long time before identifying the target and committing the killing.

So the remaining question is: where did Wei Guigui do it? That is, where was the first scene of the killing?

Is it in this woman's house? No, it's impossible, if you kill someone in the woman's house, it's easy to leave traces of yourself, in case it is investigated by the police afterwards, it will be difficult to escape the involvement, and you can't shirk it to Hong Huijian, Wei Guigui can't do such a stupid thing.

On this issue, Yun Yeyao put forward a bold idea, that is, Wei Guigui used some method to trick the mysterious woman to the top of the mountain where the Luo Que House was located, and after killing her, he took the body to the bottom of the mountain in the trunk of the car and hid it.

Maybe he prepared a sack at the beginning, a sealed plastic bag with formalin solution, and put the body directly in the mountain, hid it in the cave under the rope bridge, and covered it up with a prosthesis, but the prosthesis could not be completely sealed, and it continued to rain on the mountain these days, in case the sealed bag leaked, the female corpse would soon decay due to the humid climate, and it would not last for half a month.

Therefore, Wei Guigui had to take her down the mountain as soon as possible and put her in the walls of Hong Huijian's rental house. He must have repeatedly surveyed the condition behind that wall in advance, it was covered from top to bottom, left and right, it was dry and sealed inside, it was not rainy and the wind could not blow in, it was very suitable for storing corpses, and even if the sealed bag leaked, the formalin solution could not volatilize quickly. In this way, not only can it ensure that the appearance of the corpse does not decay before use, but also the traces of the corpse will only appear in the cave and Room 107 of Building 1 of the Huayuan Community, which will not make the police suspect Wei Guigui at all.

Although Yun Yeyao's reasoning is outrageous, it is still very possible if you think about it carefully, so the job of determining whether this reasoning is correct falls to the police officers who stay in the investigation inside the Rowque House.

They had to search the cave under the rope bridge more carefully, hoping to get a little information about Wei Guigui's activities in it, the terrain inside the cave was slightly higher than that of Jianxi, so there was no water in it, but after repeated searches, they did not get any evidence of Wei Guigui's activities.

Then the next thing to do is to identify the soil from the trunk of the Volkswagen and Mo Haiyou from the fingernails of the mysterious female corpse, if the soil samples remaining in these two places are consistent with the soil samples in the cave, it can also prove Yun Yeyao's reasoning.

The soil samples taken from the trunk of the Volkswagen and the cave were quickly sent to the police station, and the soil samples sent by Mo Haiyou were tested together, and the results came out the next day, and the three soil samples did come from the same place.

The method adopted by the police is to conduct a comprehensive investigation of migrant women who live alone, have no friends or relatives here, and whose appearance is close to the female corpse, to see if there are any mysterious missing people, because even if this type of woman is missing, no one will find it in time and report it to the police.

In order to obtain more detailed data on the appearance characteristics of the corpse, Mo Haiyou took the high-definition photos of the corpse to find the teacher Nian Bo, who taught him special effects makeup and mutilated facial restoration methods, and also learned from Nian Bo about Luo Yifan's specific actions on the night of May 7.
