I asked to release the original film sent from the train station to see, although I knew in my heart that it was a needle in a haystack, but after watching it, I could be more down-to-earth, otherwise I always felt that something was not done.

The original film was released, and there were more than twenty minutes before and after. Bai Yafeng and I both sat in the chairs and watched, Bai Yafeng found that Xiaohai was standing behind and staring at the screen, so he got up and gave her the chair. Xiaohai was not polite, and sat down.

Seeing that at the end of the day, we didn't see the problem, but Xiaohai seemed to have found something and asked me if I could go back to it.

I thought she saw the key, and immediately refreshed herself, sat up straight like a chicken, and asked the technician to go back a little.

Xiaohai commanded softly: "Pour a little more, pour again, yes, here, stop." ”

Then, she held out her hand and touched one of the men in the frame.

I asked the technician to enlarge the man Xiaohai pointed out, and then magnify it a little more. He did so obediently. After these films were sent, they were processed with high-end software for the first time, and the quality was very good, and the clarity was relatively high after magnifying many times.

Xiao Hai's eyes were fixed on the screen, and after looking at it for a while, he suddenly burst out with a sentence: "Well, it's really him, he's not dead." ”

I thought there was a breakthrough, and I became more and more excited, and immediately asked her what the situation was.

I was very anxious, but Xiaohai was not in a hurry at all, his expression and tone were like chatting, and said: "This person is a teacher in our town's primary school, he moved to the city many years ago, I heard that he was imprisoned for committing a crime, and after he came out, he made a fortune, and after he became rich, he disappeared, and many people in the village said that he had been robbed and killed a long time ago, but he didn't expect to live well." ”

I sounded a little confused and asked her, "Does this person have anything to do with the case?" ”

She looked at me a little dumbfounded: "How do I know if it matters, I just haven't seen it for a long time and suddenly see it here, and I can't help but be surprised." ”

Bai Yafeng originally had a very serious attitude, and he made the gesture that he was about to set off to catch the murderer, but after hearing this, he hit his head against the wall and said, "Alas, I'll go, it's a waste of feelings." ”

I didn't give up so quickly, after all, the world is very big, Xiaohai has seen very little of the world, and the chance of being able to recognize an acquaintance in a video involved in the case is very small, so I took a closer look, a lean and thin man, almost skinny, with slightly long hair, a long face, a pointed chin, and an ordinary briefcase in his hand.

I asked the technician to point out all the pictures with this man, and I looked at it three times, but I really couldn't see the problem, it was just a very ordinary person, very ordinary to get off the train and get out of the station, and I didn't answer the phone, didn't make a phone call, and didn't look around on the way.

For the sake of reassurance, I still asked Xiaohai what the man's name was.

She said: "I can't remember my full name, but I remember that my surname is Xia, and everyone in the town calls him Teacher Xia." ”

After I remembered it, I asked her solemnly: "Will you admit your mistake?" ”

She tilted her face to look at the computer screen, her expression was not very sure, and said: "It looks like it, but I can't be sure, after all, I haven't seen him for many years, I was a child when he left Huaqiao Town, and now this video looks a little confused." ”

I asked Bai Yafeng to arrange someone to go to the train station to check the list of passengers, and two hours later, the feedback came over there, saying that there were four passengers surnamed Xia on that day's shift, and none of them were in Liangbao City, and they didn't want to have anything to do with Yu Min, so the episode about this man turned over like this.

I asked Bai Yafeng for Yu Min's mobile phone call records before his death, and asked him if he had checked who the last few calls were made to.

He said: "I checked it, I checked it one by one, it was called to a few of her friends, the content was very ordinary, there was nothing wrong with it, she didn't tell anyone that she was coming to Qianzhou, and they didn't even know that something happened to her." ”

The call record in his hand has all the numbers in and out of Yu Min in the two months before his death, and the mobile company sent it, so there will be no mistake.

I carefully looked at the last seven or eight lines of numbers, checked the dial-in and dial-out time and call time, then took a deep breath, looked up at Bai Yafeng, and asked him in a low voice: "Is it handed over to you for verification?" Have you checked them all? ”

He didn't know why I was so serious, shook his head blankly, and told me that he had only been dealing with the video for the past few days, and the phone list had been verified by another policeman.

I breathed a sigh of relief, thinking that it was better that he wasn't the one who had gone wrong. Then he hurriedly went back to the computer department, pulled a chair and sat down, and asked the technician to pull the video progress to the place where Yu Min was talking on the phone in the crowd after getting off the train.

At 14:22 and 14:25 respectively, Yu Min made two phone calls, but there was no record of those two calls on the list in my hand.

After checking again, there really isn't.

Two phone calls were missing from the list.

The last call on the list in my hand was at 14:26, it was someone else, and it was not shown in the video because she had walked out of the picture. There are notes written by the police after verification, and the phone call was made by Yu Min's landlord in Liangbao City to demand rent, and Yu Min only said that the money would be transferred to his account in two days. In the two and a half hours before this, Yu Min's mobile phone had neither outgoing calls nor incoming calls, and the two calls she had been captured by surveillance video had disappeared for no reason. The order was from a mobile company, which was technically impossible.

I bit my lip and thought for a while, and asked the technician to enlarge the mobile phone in Yu Min's hand. He immediately chose the best angle to take a screenshot and zoom in, zoom in, and zoom in again. It's a copycat mobile phone, the kind that supports dual SIM dual standby.

That is, she has two numbers!

Yu Min used another mobile phone number at the train station to contact the person who tricked her into coming to Qianzhou City, so the call list I have in my hand now is useless.

I called Bai Yafeng and told him to hurry, hurry, hurry up and contact Liang Baoshi to see if anyone knows her other number.

He jumped up, and I knew that as long as I didn't let him keep staring at the video, it would be telling him to clean the toilet and probably he would jump too.

That's the end of the video at the train station, and then Tan Zhongxia and I went back to the conference room on the third floor, and we had to continue to discuss the doubts in the case.

I am worried about the murderer's non-compliance with the pattern, and I can't figure it out about the narcotics, I can't figure it out.

If you have to say that the murderer did not have obsessive-compulsive disorder and did not pay attention to any pattern at all, it is okay, but why was anesthetic used on the victim in the "disembowelment case"? The murderer in this case is obviously cowardly and cowardly, and he is not a butcher at all, he can choose a simpler way, such as burning a fire and throwing it into the water and drowning. However, he would rather risk having the drug found out by a forensic doctor and then potentially follow the source of the drug, or he would have anesthetized the victim before disemboweling him.

Why, exactly?

I seemed to understand something in a trance, there was a spiritual light spinning around in my mind, I desperately wanted to grab it and it seemed that I was about to catch it, but Tan Zhongxia suddenly spoke, startling me, the spiritual light was gone, and if I wanted to find it again, I had to think about it again. So I looked at him with gloomy eyes in frustration, and didn't give him a good face.

He also wanted to talk to me about anesthetics.

He stood sideways against the wall, his eyes looking at the ground, one hand half-clenched into a fist to his ear, and he assumed the posture of a very literary young man.

He dismantled the good sentences and spit them out: "First, stabbed, seven knives, all, avoided, aorta, let Yu Min bleed alive and die." And then、Again、Muscle、Anesthetics? So, in that gang, there is one, understand, doctor. ”

I really couldn't accept Tan Zhongxia's way of speaking suddenly I didn't know where I learned a few words, so I frowned and glared at him a few times, then sat down and ignored it.

He didn't mind if I thought of him as air, and kept his posture and way of speaking and muttered over what he had just said, before finally returning to his normal state and came over to me and asked me if what he had just analyzed made sense.

I only nodded slightly, but didn't say anything, and didn't even look up to look him in the eye when I nodded.

Nodding his head because I think that from the usual situation, his analysis is correct, and there should be at least one person in the murderer's team who understands surgery, and it should be related to the staff, such as doctors, nurses, anesthesiologists or pharmacists.

However, there are situations in this world that are unconventional.

I have carefully looked at the photos and autopsy reports of the corpse of the "Seven Swords Case", and the seven knives were dropped slowly and carefully, not indiscriminately stabbed in the chaos and urgency of the fight, so anyone who understands a little bit about the structure and distribution of organs of the human body can avoid stabbing the victim with seven knives in the fatal parts, and does not necessarily need to know surgical knowledge.

As for anesthetics, as far as I know, in addition to the Western medicine anesthesia commonly used in hospitals, there are also some drugs in traditional Chinese medicine that can cause anesthesia, such as tiger fly grass, horse fright grass, Qiantangji, etc. Some need to be swallowed to take effect, some are injected, and some even work immediately as soon as they are breathed into the body. Of course, these drugs are outside of the routine and are very rare in ordinary life, so I don't think much about them when the signs and evidence are not too clear.

It's just that the smell of the silver shell terrier that I faintly smelled at the scene of the "disembowelment case" that day was like a thorn in my throat, and I couldn't pull it out. The Silver Shell Terrier, the Horseweed, and the Tiger Fly Grass are all things that exist outside of the norm, so since I can smell the same thing, I won't be too shocked if there are one or two other things on the scene.

So I only agree with half of Tan Zhongxia's analysis.

There may really be a medical worker in the murderer's gang who understands surgical knowledge, as Tan Zhongxia thinks.

But it is also possible to be a person who is well versed in traditional Chinese medicine, especially the pharmacology of rare Chinese medicine, such as someone like Su Mosen or Uncle Chen.

In my opinion, the most important thing to worry about at the moment is not this, but the model.

What kind of pattern are the murderers using to commit crimes?

I had to figure this out so I could know which direction to go for the murderer, or I would have to be trapped in a web of spider silk.
