Approaching the painting again, this time focusing on the frame, I was even more convinced that the painting on the wall had been replaced.

First of all, a famous painting with a lot of value should not use a manual disassembly frame, and this frame is obviously different from the frame on the mobile phone photo. Secondly, because of the particularity of oil painting, its frame generally does not use a glass frame, if it is hung for a long time, the surface of the oil painting should be more or less dusty, but from the frame and the surface of the oil painting, I have not found any dust, indicating that the painting has only been hung for a short time.

Looking at the photo on my phone, I thought to myself, "What about the previous frame?" Such a cumbersome thing, the murderer obviously will not take it away, then it must be hidden at the crime scene. ”

So I called in a couple of surveyors and asked them to help find the frame in the photo. Soon, in the corner of the inner balcony, the frame in the photo was found, judging by the traces of demolition, it was very new, and it should have been dismantled not long ago. Moreover, there are a lot of picture frames stored in this place, so it can be concluded that the frame used for the painting hanging on the site was obtained here.

I took a turn around the crime scene again, and looked at the red wine opened on the wine shelf, this wine had already drunk half of it, and there was nothing unusual in taste, and it was inferred from the taste of wine in the mouth of the deceased that it was estimated that he had drunk this wine before his death. There were no used wine glasses at the scene, but there were two glass glasses on the wine rack that were obviously stained with water, and it is estimated that the murderer had cleaned the glasses after committing the crime.

Seeing this, I asked Lao Lu, "Did the forensic doctor make a judgment on the time of death of the deceased?" "I actually have a judgment in mind, but I hope to compare it with a more professional forensic doctor to confirm the correctness of my judgment.

"It's about between one and two o'clock in the morning today."

I nodded, and it seemed that my judgment was not much different from that of the medical examiner. But there's a problem, two men met late at night and drank red wine, which made me wonder a little. I even began to doubt my initial judgment, could it be that the murderer was a woman?

Thinking of this, I looked at the deceased's bathrobe again, so I went to the deceased's bedroom, carefully examined his bed, and finally found a little unexpected clue, a hair about twenty centimeters long, undyed, and falling out on its own.

This length of hair is obviously incompatible with the deceased's short hair, and although it cannot be proved that this hair was left by the murderer, it cannot be denied that it was not left by the murderer.

I gave my hair to Lao Lu and asked for a DNA test.

Lao Lu handed over his hair to a colleague in the evidence team and asked me, "Didn't you infer that the murderer was a man?" Don't tell me that such long hair is a man with long hair, and this man also dropped this long hair on the bed of the deceased. How likely is this? ”

I bowed my head and said nothing because my idea was ridiculous, but it was the only reasonable explanation I could think of.

At this time, Tang Zhenguo on the side said: "There is this possibility, I once lived on the border for a period of time, and often met men with long hair, some of whom are gay. ”

I raised my head and patted Tang Zhenguo on the shoulder with a smile, because what he said was exactly my ridiculous idea.

Lao Lu listened to Tang Zhenguo's words, and was a little dumbfounded, because he couldn't refute it, and he couldn't accept it. Perhaps people of our age are not very receptive to the word homosexuality.

My investigation of the crime scene has ended, and the police are still continuing to look for possible evidence, and I certainly hope that they can find some clues to move forward with the process of solving the crime.

Of course, as a consulting detective of the police, after the scene investigation of each case, I will report to Lao Lu about my detection ideas and reasoning and assumptions about the case, and this time is no exception.

Standing at the entrance of the building, I looked around, and the onlookers had already left at this time, and they should have been forced to leave by the police, because the people's curiosity is always so strong, and if there is no injunction, they can probably wait and see from beginning to end.

Lao Lu took out a cigarette, one for me and Tang Zhenguo, and as soon as he lit the cigarette, Xiao Xia hurriedly ran to us with a small notebook, smirking.

Lao Lu held a cigarette in his mouth, and said to me with some unclear words: "This kid seems to have woken up after the New Year, saying that he wants to learn criminal investigation techniques from you." ”

I smiled, my eyes fell on the small notebook in Xiao Xia's hand, and then said to him, "What, are you still going to take notes like a meeting?" ”

Xiao Xia showed a neat row of slightly yellowish teeth and smiled: "A good memory is better than a bad pen!" ”

Not without reason, I have no refutation.

Taking a puff of cigarette, I went straight to the point and said: "From the results of the scene investigation, I will first deduce the motive of the murderer. A painting by a famous artist has been replaced, so the purpose of this murder must have a lot to do with this painting. So according to this painting, such a grotesque murder case was derived, and it is certain that the perpetrator's thinking is different from ordinary people. I'm going to sort out the murderer's modus operandi now. First of all, when the murderer came to the deceased's house, he must have brought the fake with him, and a person like the deceased, who loves calligraphy and painting, will definitely ask to take a look at it curiously when he sees someone else holding a painting in his hand. If he saw the unfinished copy, how would the murderer explain it? I have a conjecture that the person who holds the painting himself is fond of copying famous paintings, and that the deceased knew that he had this hobby. After this strange painting does not arouse the suspicion of the deceased, the second step is how to make the deceased faint severely and commit theft and torture? So drinking red wine is key. Two people will not drink red wine for no reason in the middle of the night, unless the relationship between the two is very unusual. From the hair found on the bed, it can be guessed that the relationship between the two is indeed not ordinary. However, whether the murderer is a woman or a homosexual here needs to be determined during the subsequent investigation of the deceased's social scope. ”

I took another puff of my cigarette and saw that Xiao Xia was taking notes very seriously.

I continued: "From the fact that the deceased was wearing only a dressing gown and the smell of alcohol in his mouth, it is likely that the murderer used flirtation to trick the deceased into drinking strong* alcohol and making him severely unconscious. *Whether it exists or not will be known after the autopsy is released. After the deceased fell unconscious, the murderer's first step was to clean up the traces left by himself, and the fact that he cleaned the wine glass is a good proof that he did this, and of course what other things he cleaned, I don't know. The second step is to commit theft and replace the famous painting. Obviously, the murderer was very familiar with the deceased's home, otherwise he would not easily find a suitable picture frame to inlay his fake, and it is estimated that he had been prepared for the crime before, and checked the size and location of the picture frame. The step of replacing a famous painting is redundant in the eyes of ordinary people, but in the eyes of an artist, it is the key. I have already explained the reasons before, so I will not repeat them here. ”

Xiao Xia looked up at me at this time, and stopped talking, Tang Zhenguo looked at Xiao Xia and said, "There is a fox in the painting, and the murderer intends to disguise himself as a fox in the painting and jump out to kill people." After speaking, he rolled his eyes, indicating that he couldn't understand.

"Wow! Really! If it weren't for Brother Ouyang's pointing, maybe we would really be led into it by the murderer. Xiao Xia said with a smirk.

Lao Lu's face was white and red at this time.

I smiled and continued, "The next thing is that the murderer shows his cruel and delicate side. He first cut the deceased with a strange murder weapon, and then used a pre-prepared claw mold to create bloody footprints of the animal. It was this bloody footprint and the strange scars on the deceased's body that reminded me of the murder weapon used by the murderer. I just looked it up on the Internet, and this kind of thing does exist, and it is sold. ”

Tang Zhenguo's eyes widened and asked, "What is it?" Xiao Xia also looked at me directly, only Lao Lu was still squinting and smoking.

I said, "Wolverine knows it, the murder weapon is similar to the steel claw in Wolverine's hand." ”

When Xiao Xia heard this, he hurriedly took out his mobile phone to inquire, and then shouted loudly: "I'll go, there is really this thing sold on the Internet, and it is made of steel." ”

Lao Lu took Xiao Xia's mobile phone, looked at it thoughtfully, and said, "This murderer's thinking is really weird. ”

I said, "But the murderer is not rigorous, the bloody footprints are indeed the footprints of a fox, but they have four front paws, and Wolverine's steel claws are three." "Actually, this article doesn't help with handling the case, I'm just ridiculing the murderer.

Then we checked the surveillance video of the community, and a man with a ponytail, a mask, and a painting tube on his back caught our attention. Obviously, the characteristics of this person and the murderer are very similar, so the male murderer of homosexuality is more likely than the female murderer.

The scene of the crime was handed over to Xiao Xia and the investigating police, and I, Lao Lu and Tang Zhenguo went straight to the calligraphy and painting shop of the deceased Cao Weihu.

The calligraphy and painting shop is called Qihuaju, which is located in the pigeon ditch antique trading and distribution center, and is still open as usual.

"Strange paintings, strange paintings, it's a bit of a strange thing to live in." I looked up at the quaint green plaque with black background and teased. At the same time, it was found that the signature of the plaque was also Yu Jinmo.

"Ouyang, look at the inscription of the plaque on the door, it is also Yu Jinmo." It seems that Lao Lu also found out.

I said: "Yes, the relationship between Yu Jinmo and Cao Weihu is very unusual, let's go, go in and ask." ”

Walking into the calligraphy and painting shop, I found that this shop is very classy, about 60 square meters in the center of the store, is a circle of glass counters, under the bright lights in the counter, there are both exquisite four treasures of the study, there are also famous inscriptions and paintings of incense fans, the surrounding walls are very regularly hung with all kinds of calligraphy and paintings, all of which are finely framed and beautiful.

A man with gold-rimmed glasses and a white Chinese robe was standing in front of a table covered with white cloth to paint, and when he saw us walking into the store, he quickly put down the brush in his hand, stepped forward and saluted with a fist: "I don't know what your distinguished guests need?"

This dress, this posture, I thought I had traveled to the Republic of China period.
