Lao Lu did not drive back to the team, but went directly to an auto repair shop in Guanyinyan (place name), because during the inquiry of Feng Xiaoke, he learned that Feng Xiaoke's private car was being maintained here.

I know Lao Lu's plan, he wants to confirm whether Feng Xiaoke's private car wheel prints match the suspicious wheel prints I found? In fact, I want to tell him that the possibility of matching is very small, how could a woman as shrewd as Feng Xiaoke drive her own car to engage in criminal activities? But everyone has their own detection ideas and tracks, and I can't break Lao Lu's detection track, let alone pour cold water on his head.

We quickly found Feng Xiaoke's car, which was a brand new red Porsche McCashy. Of course, as I expected, the tyre pattern of this McAy did not match the wheel print found at 'Feng Zhuang'.

Lao Lu said: "It seems that the only way to carry out a large-scale investigation is through the monitoring on the Da Ya Pass line. ”

I said: "There are not many cars in Da Yakou in this weather, it should not be difficult to investigate, but the difficulty is that even if the car is found, where is the final location of the car?" This may have to trouble the brothers to work overtime. ”

Lao Lu smiled bitterly and said: "Where are we policemen who still have the saying that we don't work overtime, and we have to work hard before the case is solved." It's okay today, you can take a taxi home, I'm back in the team. ”

I nodded, knowing that Lao Lu had to spend the night in the team again today.

After Lao Lu left, I saw that it was still early, so I said to Tang Zhenguo: "How about we take a walk and chat for a while?" ”

Tang Zhenguo said okay.

Walking on the sidewalk, the cold wind made my brain very clear, and the doors of roadside stores and some units were full of red lanterns, these red lanterns stimulated my vision, and made my head appear a lot of strange ideas. But what I want to talk to Tang Zhenguo about at this time is not these strange thoughts in my head, but about his apprentice, Tang Zhijie.

Took out two cigarettes, handed one to Tang Zhenguo, the two of us lit it almost at the same time, in the smoke, I said as I walked: "Can you talk about your apprentice Tang Zhijie?" ”

Tang Zhenguo also asked bluntly: "Are you suspecting that he is the murderer of Feng Chicheng?" ”

I said: "In terms of height and flying knife skills, he does have something to be suspicious, but his motive is difficult to figure out, because it is difficult for him to connect with the Feng family." The only thing I could get in touch with was my guess. ”

"What conjecture?"

"Didn't he say before that he saw Yang Shiruo's ghost? I boldly imagined that what he saw was not a ghost, but Feng Xiaoke. ”

"I don't get it."

"Do you remember the bloody plot I said when I was masturbating?"

Tang Zhenguo took a puff of cigarette and said with a smile: "You said that Yang Shiruo is an abandoned baby of the Feng family, but she is actually Feng Xiaoke's twin sister." That's. ”

"It's. However, Yang Shiruo and Feng Xiaoke look too similar, even if there are too many coincidences in nature, why did this kind of coincidence meet in the bizarre case of Liangzhuang? Could it be a coincidence within a coincidence? What do you think? ”

"What a coincidence!" Tang Zhenguo's tone was also a little uncertain.

"Since this is the case, I will assume that Yang Shiruo is related to Feng Xiaoke, and this hypothesis actually has a way to prove it. It is to compare Feng Chicheng's DNA with Yang Shiruo's DNA, if the comparison is in line with the close relatives, then many problems can be easily solved. ”

"Hmmm! Tell me how to solve those problems. ”

"Nope! Let's talk about your evaluation of your apprentice first. ”

Tang Zhenguo squinted his eyes and took another puff of cigarette, then frowned and said, "Since I am now your assistant and stand in the position of solving the case, I will not protect anyone." If I were to evaluate Tang Zhijie, I would say that he is very talented in knife throwing skills, calm, decisive and composed. But there is one thing I don't really like, he is ruthless and vindictive. ”

I hurriedly asked, "Ruthless?" Vindictive? Are there any specific manifestations? ”

"Yes, a few years ago, he was drinking at the night market, and he had a confrontation with some drunkards, because he beat them very badly, and one of them broke his leg, because he was detained for this matter. Afterwards, I learned that it was just because of the narrow space and the plastic beach chair backrests resting on each other when drinking. Just because of this incident, he broke someone's leg, which is ridiculous, and it can be seen that he is very ruthless. ”

"How do you see a strong sense of revenge?"

It wasn't for the sake of it, but it was told to me by his father. Tang Zhijie is a single-parent family living in the countryside, and his mother went to Shenzhen when he was very young and ran away with a boss in Shenzhen. Everyone knows about this in the village where he lives, so he feels inferior and shameless since he was a child. But maybe he has that kind of ruthless character, and he can't tolerate others mentioning this in front of him. A child of the same age once mocked him in front of him, and he smashed the other's head with a stone on the spot, and then destroyed the land where the child's family planted. It was because of these things that his father sent him to me to study art. ”

I hummed, thinking about Tang Zhijie. Single-parent families, who have psychological baggage since childhood, have a ruthless spirit, a strong sense of revenge, and have practiced a stunt, such a person is likely to embark on the road of crime under some specific conditions. And now this condition seems to have appeared, and that is the death of his girlfriend. If he knew that his girlfriend was poisoned, then with his character, it is very likely that a knot will appear in his heart, and it is very likely that this knot will force him to embark on the road of revenge.

Tang Zhenguo snuffed out the cigarette butt and threw it into the trash, turned around and said, "I'm done, you can tell me your assumptions." ”

I said solemnly, "My hypothesis is not perfect, and I will tell you when it is perfect." ”

Tang Zhenguo's face showed some disappointment, and I smiled: "Don't worry, you will definitely not miss a good show." When I think about this sentence later, it is very unpleasant, because what awaits Tang Zhenguo is not a good show, but a bitter play.

I thought about it all night, and the more I thought about it, the more I felt that the relationship between Yang Shiruo and Feng Xiaoke was not simple, and a bold hypothesis kept echoing in my brain. Because of this assumption, the death of Yang Shiruo, Uncle Mao the clown and Feng Chicheng is perfectly combined. In order to prove the possibility of this hypothesis, I dragged Tang Zhenguo to the criminal investigation team early the next morning, because if I wanted to solve the mystery in the hypothesis one by one, I had to rely on the power of the police.

Seeing the sleepy-eyed and tired old Lu, I asked with concern: "What?" Didn't sleep well? ”

Lao Lu took a sip of water from the steaming teacup and said, "It's almost the New Year, and there have been three murders in a row, can I sleep well?" By the way, the suspicious cars of 'Feng Zhuang' have been investigated, you see. ”

Lao Lu handed me a photo of a black sedan with a license plate from the main city of Chongqing, because it was night, and the driver couldn't see it clearly.

Lao Lu said: "This is a screenshot of the video, the license plate has been checked, guess whose it is?" ”

I said, "Feng Ergongzi's." ”

Lao Lu looked at me in surprise and said, "How do you know?" ”

I said, "The housekeeper of the Feng family said that the second son of Feng is in Chongqing, and he couldn't be contacted all day yesterday, which is very suspicious. When my father dies at home, there must be a lot of things to deal with, and it is difficult to make sense of not answering the phone and disappearing at such a time. So the only person left who can think of something related to Feng Chicheng's death is Feng Ergongzi. What's his name? ”

Lao Lu said: "It's called Feng Wanli." ”

I said, "Galloping thousands of miles, it is indeed two brothers." ”

Lao Lu said: "I contacted the housekeeper, and the housekeeper said that there has been no news of Feng Wanli, and Xiao Xia has already inquired about the hotel where Feng Wanli stayed in the public security system." ”

Just as he was saying this, he heard hurried footsteps, and then Xiao Xia ran to Lao Lu and said, "Team Lu, I found it, I came to the hotel at Hyatt." ”

Lao Lu gave an order: "Let's go." ”

Sirens sounded, and three police cars headed straight for the Hyatt Hotel.

However, when we found Feng Wanli in the hotel room, he had already died.

I checked the scene of the murder and there was a 'Do Not Disturb' sign on the handle of the room door all the time, so the hotel staff did not find the deceased in time.

There was no heating in the room, but the windows were open, and since this was the 16th floor, there was no need to worry about anyone outside seeing the inside of the room. The windows are opened to allow for a cooler temperature in the room, so that the corpse will be smelling for a longer period of time, and the time it will take for the corpse to be found.

The deceased was lying on a bed with a messy bed. He was wearing a gray cardigan, black trousers, and the hotel's white disposable slippers were placed irregularly on the side of the bed, one of which was still buttoned. There was a visible needle hole in the neck above the right clavicle and some blood stains, while the deceased had slight bruises on the wing of his nose. It is assumed that the time of death has been more than 24 hours. The exact circumstances of the death will require further confirmation from the medical examiner, but I made a simple inference at the scene to explain how the deceased was killed.

I pointed to the eye of the needle in the neck of the deceased and said, "Look at this wound, it is obviously a needle hole, but it is much larger than the eye of the syringe, and it is not very awkward to attack this place if you want to stab this position and attack it at close range." If you have a syringe in your hand and you want to hit a person's neck head-on, it must be on the outside of the neck, how can it leave a scar above the inner collarbone? I deduce that the eye of the needle must have been left behind by a murder weapon like a dart. ”

Lao Lu followed closely and said, "Darts? That's very similar to Feng Chicheng being killed by a flying knife. ”

I said, "Yes, but I can't confirm if it's the same person." ”

Lao Lu said again: "Indeed, if it was the same person, then the murderer should have used a flying knife." ”

I said, "Not necessarily." The murderer killed Feng Chicheng with his back to the deceased, and then delivered a fatal blow. And the terrain here is narrow, and it is difficult to carry out a sneak attack, so you have to fight head-to-head. When the opponent is on guard, the chances of delivering a fatal blow are much smaller. If the victim screams for help and the hotel guests and staff can easily find out. But if you use a dart with a strong anesthetic, such as *, to make it unconscious in an instant, will the success rate be higher? ”

Lao Lu nodded and let me continue.

Then I pointed to the wing of the deceased's nose and said, "You see, there are bruises on the wing of the nose, which means that the deceased was pinched by his nose and covered his mouth before he died. You think, how can a person easily let people pinch their nose and cover their mouth? It means that he was already unconscious at that time, and what caused him to be unconscious was the dart with a powerful anesthetic. The cause of death of the deceased must have been that after he was anesthetized and unconscious, he was pinched and covered his mouth, resulting in suffocation. ”
