After the technical investigators and forensic doctors initially collected evidence, Song Xichen and Han Yijing also entered the scene.

The hidden compartment was so small that it didn't even have a light to illuminate it.

The person in charge of the exhibition also said that this place was rented temporarily by them, and it was only rented for a month. This hidden compartment is only used for some paintings, and it is generally not opened.

The floor of the hidden compartment was covered with several gray marble floors, surrounded by concrete walls, and the roof was covered with pipes for unknown purposes. The room was empty, with only a few paintings standing on the floor around the walls, and nothing at all, and the painter Lily was hanging from the pipes.

There was nothing under her feet or even in the whole house that could be leveraged, and she hung so high for the only reason, she was hung by someone else.

Han Yijing saw the corpse lying on the ground at the moment, and the more she looked at it, the more she felt that this person was more familiar.

Confused, she asked, "Who is she?" ”

Song Xichen knew that Han Yijing probably recognized her, and he said: "The deceased is Kang Ziyan from the key middle school of City A, class 289 of class 3915. ”

Han Yijing was sick for a moment, and sure enough, it was their classmate, this person was the Kang Ziyan who had been with others on the basketball court and wanted to bully her.

At this time, Dr. Jia had already completed the preliminary examination of the body, and he got up and made a preliminary inference: "The victim should have died of suffocation, but there were two strangulation marks on his neck." One is supposed to be formed by hanging on the beams of the house, with deep strangulation marks. The other strangulation mark is a little shallower. Although the stomach was cut, there was no clotted blood clot, so it can be inferred that the deceased was dead at the time of the cut. The rest will be further checked back to the bureau, and after the inspection, I will give you a specific report. ”

Song Xichen nodded: "Well, you can do it as soon as possible, Lao Jia is going to work hard again this time." ”

Lao Jia shook his head and said, "My own work is not hard or hard. I'll check it out as soon as I can, and I'll report back to you. ”

After saying that, the hometown left.

Song Xichen and Liu Yiqiang both squatted down at this time to carefully and carefully inspect the corpse, and looked around, this place was very small, and it could be seen at a glance that there was no trace of a fight here. If this is really the first scene of the crime, then the murderer must know the victim. So what is their relationship?

As soon as Han Yijing walked into this hidden room, the aura from this shop still made her feel that the bloody atmosphere here was too thick and too dark.

It made her feel very uncomfortable.

But she tried her best to adjust her mentality, so that she immediately got into the state of work.

Instead of approaching the body first, she looked around, carefully looking at the paintings that lay out on the four walls. The style of these paintings is basically the same as that in the exhibition, and each painting has a signature on it, so these paintings should be Lily's, that is, Kang Ziyan's.

After she looked at the paintings, she said with some certainty: "This should be the first crime scene, and this place is probably used to store the paintings temporarily." The paintings are neatly arranged, and each painting is numbered at the back, and it is also arranged according to the number. But only the paintings on this wall are not placed in numbered order, and one of the paintings is reversed. ”

Song Xichen raised his head and said, "You mean, after the murderer killed, he leisurely sorted out the overturned paintings again." ”

Han Yijing did not answer, and acquiesced to this statement.

Song Xichen told Liu Yiqiang beside him: "Go and ask who is responsible for cleaning up this hidden compartment and call that staff member." ”

Soon Liu Yiqiang called a male staff member aged twenty-four or five.

Song Xichen asked, "Are you responsible for sorting it out here?" ”

The male staff member said: "Yes, it's Sister Li - the person in charge of our exhibition arranged for me to sort it out yesterday." ”

Song Xichen then asked, "Then is there a key to the hidden compartment here?" ”

The staff replied: "There is no key here, this hidden compartment is relatively hidden, and the general staff don't know about it, and the painter Lily, Sister Li, and I know it here." Most people think it's a wall. And there are cameras everywhere in this exhibition, so I don't have to worry about the paintings inside being stolen. ”

Song Xichen finally asked: "Is there an order for the arrangement of the paintings here?" ”

The male staff member added: "Of course, there is an order, and each painting has a number on the back border, which must be arranged by number. Song Xichen asked again: "Then did you accidentally put the painting upside down?" ”

The male staff immediately denied: "All the paintings must be put in accordance with the number, and they must not be reversed, which is found by the person in charge, and I will be fired directly." After I put it away, I also checked it again, and it is impossible to have a random number or put it in reverse. ”

Song Xichen nodded and signaled that the staff of the exhibition could go out and take notes.

Liu Yiqiang immediately put all the paintings into the evidence bag, and handed them over to the technical investigators along with the others to see if there were any clues.

It seems that Han Yijing's conjecture has been confirmed again.

So why did the murderer not leave the scene immediately after the murder, but still tidy up the scene? Isn't he afraid of being discovered?

Song Xichen looked at the two strangulation marks on the corpse's neck overlapping and extending in different directions. According to his years of criminal investigation experience and technology, Kang Ziyan must have been strangled from behind first, and then hung on the pipe.

The killer watched her struggle from the point to the end of her life, and after she was completely dead, he also cut her belly, and the knife marks on her clothes and stomach were not clearly neat, and he obviously did not use knives very often.

Han Yijing also came to the side of the corpse and looked at this once familiar classmate. She really wanted to ask Kang Ziyan, who are you here? What is your relationship? What are you doing here?

It's a pity that the deceased won't tell her, but the deceased might tell the medical examiner. They should wait for the results of further medical examiners.

Han Yijing said: "The people who came here with Kang Ziyan, that is, the murderer, may be very familiar with her, they may come here to see paintings, or it may be other things, something that must be carried out in this hidden environment." And I don't know what it is.

And Kang Ziyan should be a person who has a good impression or respect for the murderer, she dressed up herself, from her clothes, shoes, to her beautiful red dress.

But the murderer should have hated Kang Ziyan very much, otherwise he would not have been indifferent to watching her hanging, and the deceased was disemboweled. This hatred is very clear.

And why did the murderer tidy up the paintings in the corners? Afraid that people will find out? Apparently not, and it was this large bloodstain that flowed out that reminded people that something unusual was happening here. It can be seen that the murderer has no remorse for the murderous thing he did, he is even a little proud and excited, and he is very eager for this matter to be discovered. And the more commotion this incident caused, the more excited and happy he became.

So there may be an explanation for his arrangement of paintings, he must have a certain degree of obsessive-compulsive disorder in his daily life, and he doesn't like the random placement of things in his field of vision. And there is a certain pattern in his placement, which is in order from largest to smallest.

It's just that he ignores that Kang Ziyan's paintings are arranged by number, not size. ”

Song Xichen also nodded, and asked the personnel of the forensic team to carry the body away first.
