Sure enough, there are loopholes in community monitoring, since there is a person, then the more critical the person, the more this person will appear, it is better to catch a turtle in an urn, Jiang Xu thought to himself, if there is no evidence, then force people to show their feet.

"Su Yang, remember the mysterious person in Li Haonan's office I told you yesterday! Let's go to the monitoring room of Li Haonan's company to check it now. Su Yang nodded, trotted over and hurried to drive.

Jiang Xu felt that the case was getting clearer and clearer, and he could basically lock the target, and the testimony that Mr. Zhang said was absolutely inseparable from Li Haonan.

"Let's go to the company now, don't go to Li Haonan first, and contact the security department directly to get information!" Jiang Xu instructed, Su Yang also knew that she didn't want to startle the snake, so after thinking about it, she felt that she should be cautious.

The two of them went to Zhang Qing's company one after the other, and it is likely that they will become Li Haonan's assets after that, according to the logic of the reasoning of the case, Zhang Qing's tragic death at home alone shows that the murderer is very urgent, and even hates the victim.

Moreover, the method of killing is so cruel that it can only show that it is a non-professional killer, and it belongs to ordinary people who committed the crime, and with the clues and traces left behind, all kinds of phenomena indicate that it was an acquaintance who committed the crime, but there is no strong evidence to determine that Li Haonan hired a murderer.

"We are from the Municipal Public Security Bureau, and now because of the murder of your former chairman Zhang Qing, we need to retrieve the surveillance video of your company building. ”

The security manager was very cooperative, "Comrade policeman, this is the video you wanted." ”

"Adjust it a little faster, yes, this time, zoom in a little bit. "There's only a back, wearing a hat, and you can't see the face at all.

"We may need to study these materials again when we go back, we can make a copy!" The manager was a little hesitant, as if he couldn't make the decision.

"I'm sorry, we can't be the master of this, let's ask our President Li and talk about it!" Su Yang wanted to come forward but was stopped by Jiang Xu.

"It turned out to be two police officers, both of whom were ignorant, and the police officers naturally had to cooperate with each other, and I would fully cooperate with whatever cooperation was needed. At this time, Li Haonan suddenly came, and a dignified boss actually came back to the security room, which made the suspicion even more aggravated.

"It's still Mr. Li's reasoning, Su Yang hurry up and copy it, don't delay other people's work. Jiang Xu was also polite, and Li Haonan looked upright, as if she had nothing to do with Zhang Qing's death at all.

"The police and the people cooperate, besides, Zhang Qing and I are still good colleagues, I fully support her affairs, and the police officers must tell me in time if they have any progress, and I deeply regret her tragedy. ”

He almost sobbed when he said it, and Su Yang almost believed his pretentious posture. It's just that the more he cares about the progress of the case, the more suspicious it becomes.

"Alright, you're done. Su Yang took everything properly, Jiang Xu came out with her, but she saw a person staring at them sneakily, Jiang Xu noticed it from the moment he came out.

"Do you see the man in the hat in the middle of the two o'clock? He was a little suspicious, he kept staring at us, the newspaper was taken upside down, you go first, I followed him. Sure enough, the two acted separately, Jiang Xu and Su Yang turned on their mobile phones to locate them, and Jiang Xu drove the car to follow behind.

With tacit understanding, Jiang Xu followed behind in no hurry, there is indeed some rhythm of an investigator, as a forensic doctor, there is no chain in this regard.

Su Yang admired him even more, that mysterious person really couldn't sit still, they were stared at by this person from the time they came to Li Haonan's company, it was indeed suspicious.

Following the mysterious man all the way to the corner, Jiang Xu didn't dare to follow too closely with his years of experience in handling cases, and stopped and stopped, but the more this was the case, the easier it was to lose it.

Sure enough, he turned around another fork in the road and was thrown off, Jiang Xu looked at the empty alley, slightly embarrassed, and let people escape from under their noses in broad daylight.

"Damn, it's really cunning!" Jiang Xu cursed, but he could only meet Su Yang first, since he could lock on to this murderer, he wouldn't be able to catch people.

"Su Yang, where are you? The person is lost, I will join you now, well, okay. After Jiang Xu came out of the alley, Su Yang's car was parked outside, and when he got into the car, Jiang Xu carefully analyzed this series of information points, closed his eyes and concentrated.

Su Yang whistled, ruffian, no matter how you look at it, he doesn't look like a policeman, but it's true, for this reason, Su Yang himself is a little inflated, but he still looks good at handling these cases.

Back at the police station, as soon as they entered, there were a bunch of people waiting there, which made Jiang Xu a little flattered, originally they received a call from the team on the way, but Su Yang didn't tell Jiang Xu.

"It's just waiting for the two of you, and you're ready to go. "Each person in charge of the case involved has in his hands the evidence he has gathered, including some reasoning.

Jiang Xu casually found a stool to sit down, and Su Yang followed closely behind, leaning against the corner of the table. "Let's talk about it! Now analyze all the information you have in your hands!"

"Then I'll first analyze the results of our trace detection in Zhang Qing's house, and it does verify that the footprints on the window sill are artificially faked, so why didn't any traces of picking the lock be found, and since there are no such conclusions, how did the murderer enter the apartment?" This is the result of one of the case handlers.

According to Mr. Zhang's testimony, we can know that it was he who provided the opportunity for the murderer to make a mistake, and the murderer actually let Mr. Zhang open the door to successfully enter, which can be confirmed. ”

Everyone was a little dumbfounded, and when they saw Mr. Zhang's confession, it became clear that they were indeed being used. It can also be seen that the footprints at the window entrance are indeed the murderer's tricks, and he happened to miss the surveillance camera, successfully creating this illusion.

"Let me say it again, according to the profile, it is preliminarily judged that the murderer is about 30 years old, weighs 145 pounds, is about 1.7 meters tall, and according to Mr. Zhang's description, he has preliminarily synthesized a 3D portrait of the front face. ”

Everyone looked at the man on the projector, although they were not impressed, but Jiang Xu had seen his side face, it was the person who monitored them under Li Haonan's company, just to understand the connection between Li Haonan and this person, the truth was not far away.

"Yang Wen, I have already seen this person in Li Haonan's company, he is staring at us sneakily, this must have nothing to do with Li Haonan. ”

"Indeed, Jiang Xu and I have long suspected that Li Haonan is behind the tragedy of manipulating Zhang Qing, and this person is indeed exactly the same as what we saw. Su Yang added that Yang Wen also knew that Li Haonan was the biggest beneficiary, so he had already sent someone to keep an eye on it.
