"What's wrong? Is there something wrong? He Ning took a closer look, and felt that there was nothing special about this small video taken by Fang Yuan, it was just a picture of herself and Tang Li standing on the side of the road face to face, sometimes closer, sometimes farther away, but she hadn't seen the video of Dai Xu and Yang Zhiyuan provided by the witness, and she didn't know what the picture of that video was like, so there was no way to compare, she could only judge from the expression of Tang Li's frowning now, there might still be something wrong.

"It's not the right angle." As he spoke, Tonic took the not-so-long video back and replayed it.

"Is it because I chose the corridor window on the third and a half floors, so the angle of Sun Dagang's shooting is half a story higher?" Fang Yuan's heart jumped a few times when she heard Tang Li say that the shooting angle was wrong, but for the sake of insurance, she still asked Tang Li what he meant again to ensure accuracy and objectivity.

Tang Li shook his head, his brows furrowed, but his tone became more and more determined: "It's not high, it's not high enough." ”

"Not tall enough?!" He Ning was stunned for a moment, turned his head to look at Fang Yuan, who was sitting in the back seat, his expression was a little surprised, "Normally, that Sun Dagang was shot from the window on the third floor, you are on the third floor and a half, you are already half a story higher than him, but if the shooting height is lower than that video, wouldn't it be equal to ......?"

Before she finished her words, Tonic added again: "In addition to not being high enough, the angle is still not the same, I can't tell how big the specific gap is now, but I can determine it from memory." ”

"So I doubt it. That video was not filmed by Sun Dagang at all. Fang Yuan heard him say this, and only then did he say his assumption that sounded a little bold, "I didn't have such a guess originally. But after meeting Sun Dagang himself, I think there are a lot of doubts in his reasons and attitudes, just like he seemed to be sure that this video would definitely become a valuable clue before he provided the video to us, his behavior feels particularly deliberate, will it be from the beginning, this is not from his original intention, but someone else instructed him to do it. And it is very likely that he has received some benefits from the other party, which I speculated based on his reaction to the fact that the public security bureau should give me a reward after confirming that the video was valuable. The man who instructed him to do so. It may be that a certain amount of material temptation was promised, and the promise was very simple, as long as the video was provided to the police for the reason that was said, and there would be no follow-up to anything else. So Sun Dagang saw me and went to him. There is a kind of impatience that may be manifested for two reasons, one is that the police came to the door again, which is different from the promise of the person who instructed him to provide clues, which may make him feel a little dissatisfied, and the other is that he thinks he has completed the task, so he is relaxed mentally and mentally, and he did not expect that I would suddenly run to find him. I thought I had been killed, so I was a little flustered. After all, there are times. The more panicked some people are, they go on a date and use emotions such as annoyance as a cover. ”

"You're right, it seems that you have learned a lot from Dai Xu this year." Tang Li nodded, agreeing with the views Fang Yuan had expounded before, and by the way, he also affirmed Fang Yuan's careful thinking and observation.

"In fact, in addition to these, there are a few things that I have been a little unable to figure out, but I don't know if I am thinking about it right, it is not a big thing, it is all some trivial things." Fang Yuan hesitated slightly, she actually had some other questions, but she didn't know if it made sense, she was afraid that she would make people laugh if she said it, but if she didn't say it to Tang Li and He Ning, there was no one else to say.

"It's okay, just say whatever you think, it's all your own people, don't worry." He Ning encouraged her.

Fang Yuan nodded and said, "I have been recalling some details of this case over and over again in the past two days, and I always feel that there are some small links that I didn't consider at that time and something is not quite right. For example, we found a very clear trail at the scene, and we deduced that these footprints should have been left by the informant, right? ”

Tang Li and He Ning nodded, although He Ning did not follow him to the scene to see the situation there, but after participating in the investigation, he had also seen the photos taken at the scene, so he knew very well about the clear footprints from the door to the living room, as well as the analysis of the footprints, and there was no doubt.

"But there's a question, I don't know if you've thought about it," Fang Yuan paused, and then continued to say to the two of them, "Why are there such clear footprints left from the moment you enter the door to the living room, but according to the conclusion reached by the colleagues of the criminal technique when they investigated the scene, no fingerprints were found on the door?" Could it be that when the informant arrived at the scene, the door of the house was wide open, so he did not need to touch the door with his hands to enter the scene of the crime, and then, after seeing the body, he was frightened, turned around and ran, and did not bother to close the wide open door at all? ”

This hypothesis was a possibility that Fang Yuan could think of as the only one that could be explained.

"Impossible," Tonley shook his head without thinking about it, "I was one of the first to arrive at the scene that day, and the door was open, with only a very narrow crack in the door. ”

"Isn't that unreasonable?" He Ning clapped his hands, "Look! Even when the informant appeared, the door was wide open, he rushed in, found that something was wrong, was frightened or some other reason, turned around and ran, and when he ran out, he closed the door with his hand, and there should be fingerprints on the door! ”

"Yes, about those shoe prints, didn't the criminal colleague also say it, you can see that the person strode in when he came in, and his steps were messy when he went out, so he should have run out, so if this is really the case, he doesn't even have the time and energy to dispose of the footprints left on the ground, why can he do not leave any handprints on the door? In the end, it's because of wearing gloves. Or has it been wiped? Fang Yuan continued to explain the reason why he had a reason for this matter, "I have also thought about it carefully, the door is the easiest place to leave fingerprints. After all, when you go out or come in, you will inevitably touch the door with your hands, even if it is not left by the murderer, not by the informant, at least there will be fingerprints left by other people, there is no reason why not a single valid fingerprint can be extracted on the door, so it can only be explained. The door had been carefully wiped down by the minifigures. So although there is a possibility that the informant was wearing gloves, so only footprints were left and no handprints were left. I couldn't help but have another association. Is it because footprints do not represent any specific personal information other than being used as a basis for estimating the person's height, weight, and age, but fingerprints are different? Suppose fingerprints are left. Just compare the information in the fingerprint database. If this person has a criminal record, he can be identified at once. ”

"Also, does this reporter really exist?" He Ning followed Fang Yuan's train of thought, and also had another question, "While listening to Fang Yuan just now, I thought that the identity of the deceased is now Yang Zhiyuan, so the assumption that the 'Li Jiawei' who rented the house with ******** may be the deceased is unlikely to be true. Let's not mention whether Dai Xu's suspicion can be established for the time being, just talk about this 'Li Jiawei'. Who would go to great lengths to get a ******** to rent a house? The work information he revealed to the landlord before is also fake, I think this is very revealing, at least it shows that this 'Li Jiawei' is more suspicious, and what secrets are hidden in it. Since he is definitely not the victim, we guessed through the video screen that he may be the informant who made the anonymous call, but who said that the two roles of the informant and the perpetrator cannot overlap? Isn't there such a word as a thief shouting to catch a thief? Maybe the reporter and the murderer are the same person at all, deliberately tricking the mystery, leaving some footprints for us to check, and the investigation can't find anything substantial, the most critical fingerprints are wiped clean, disrupting the line of sight, so that we have no way to determine the true identity of the other party, but we still think that there is a virtual reporter who does not exist at all! Isn't that also a very likely hypothesis? ”

Tang Li looked at He Ning, then at Fang Yuan, and was silent for a while before finally nodding and saying, "The hypotheses put forward by the two of you have a certain amount of truth, although they can't be verified immediately for the time being, at least it makes sense, but the most important and critical question now is that if Dai Xu was wronged, then how could half of his fingerprints appear at the scene of the crime, and no one can explain this problem now." ”

As soon as he said this, Fang Yuan and He Ning fell silent for a moment, how did Dai Xu's fingerprints appear at the scene of the crime, this is indeed a problem that no one can give a reasonable explanation, the most important thing is that it is not enough to just give a so-called reasonable explanation, it must also be able to be confirmed, otherwise it is to find another suspect who is more obviously suspicious than Dai Xu, and has direct evidence to prove it.

However, Fang Yuan and He Ning couldn't tell which of these two methods was more difficult to implement.

"I think there must be a way to forge fingerprints, as I said before, Dai Xu from his standpoint, there is no need to do such a thing to Yang Zhiyuan, including the modus operandi and style are not consistent with Dai Xu's consistent personality, even if we don't talk about these things, let's just say that we temporarily assume that Dai Xu is the suspect in this case, so with his carefulness, there is no blind spot left on the door, so that the colleagues of criminal skills can not extract any effective fingerprints, How could it be that half of the fingerprint was missed? If I'm not mistaken, that half of the fingerprint is on the tile of the bathroom wall, about this height," Fang Yuan said as he gestured towards his knee, "With my height, the position of that half of the fingerprint is higher than mine, with Dai Xu's height, it is even lower, even if he squats, his hand subconsciously supports the height of the wall, which is higher than the position where the fingerprint was found, which is even more strange, Even if you don't consider whether a person who wipes the door inside and out without leaving any fingerprints will be careless when cleaning up the bathroom, just talking about the height of that position, what kind of posture and what kind of purpose will Dai Xu have to touch that position? I think the location of that fingerprint is very strange. ”

After she said this, she looked at Dai Xu and He Ning's reactions, and both of them nodded, so she continued: "Also, I have the same point of view as He Ning just said, I think this 'Li Jiawei' is the key to the whole case, the house was rented by him, but Yang Zhiyuan died inside, which shows that there are contacts between him and Yang Zhiyuan, so' Li Jiawei, as the lessee at the scene of the crime, has a false identity, and it can be determined that he is not the victim, and he is still missing, so his suspicion is very big, which is the key point of the case. ”

"You can send me the video you just recorded," Tang Li thought for a moment, and Fang Yuan gestured, "I'll take it back and give it to the person in charge of the investigation, so that they can compare it and make a judgment." ”

"Don't say it's Fang Yuan!" He Ning told Tang Li uneasily.

Tonic didn't speak, just handed her a "I'm not stupid" look, and then Fang Yuan said: "I will tell them that I asked someone else to take pictures with my mobile phone, so as not to reduce the credibility of the evidence if you are involved." ”

Fang Yuan nodded, took out his mobile phone and sent the video he had just shot to Tang Li, in the process of video transmission, she suddenly realized something, looked up at Tang Li, and said to him: "You said, the video I took was transmitted to your mobile phone, and when you show it to others, you can lie that you took it yourself, so can't Sun Dagang, who provided clues, also use the video sent to him by others to pretend that he was filmed by himself?" Otherwise, why is there such a strange thing as the wrong angle? The best explanation is that the person who shot the video did not live in Sun Dagang's house at all. ”

Tonic had a similar point of view, bowed his head slightly, and said, "I will report this matter as soon as possible, so that the person who is now in charge of investigating this case will not forget to pay attention to this witness." (To be continued.) )
