"The policy is missing?" Guan Zheng asked. Pen "Fun" Pavilion www.biquge.info

Li Chongyang nodded and said, "We really didn't find the insurance policy, we will search again, but don't get too much hope." ”

Xu Jiuyan screamed, "This case won't just die here, right?" ”

Guan Zheng has also seen a lot of cases, so naturally he is not as anxious as Xu Jiuyan, and said: "Who told you that this is a case?" Is suicide a criminal case? ”

"Then why are we bothering so much?" Xu Jiuyan said.

Guan Zheng was really impressed by Xu Jiuyan's innocence, and said, "Can you use your brain?" If it really doesn't work, I'll let you look it up? In this case, the source of Wang Dawei's drug is unknown, and although potassium dichromate is not a controlled drug, it is difficult to get it.

The second is Wang Dawei's insurance, 2 million insurance, where did he get so much money? A person who is old and young chooses to commit suicide, and is afraid that he will not be able to jump off the building and die and prepare poison, what does this mean? This shows that he is determined to die. So the biggest possibility is that after Wang Dawei's death, this insurance will have compensation. There are so many suspicious points, of course, we have to investigate. ”

"Then you mean, Wang Dawei cheated on insurance?" Xu Jiuyan asked in confusion.

Guan Zheng shook his head and said, "It's not good to say this, the point is where the 2 million came from." There is also the insurance policy and account book of the rich fat man, which must be checked clearly. ”

"Understood."

This fat man's heart is really big enough, he sits in the conversation room as if he has nothing to do, and he doesn't eat a bite of food sent by the police. Until the police sent him out of the gate, it was the fat face.

But what everyone didn't expect was that two hours after Qian Fatzi walked out of the gate of the police station, someone sent a video of the kidnapping.

Guan Zheng looked at the video calmly, but there were no clues. Xu Jiuyan said angrily: "This lack of virtue will let him die." ”

Guan Zheng smiled slightly and said, "I agree with your opinion. ”

"Are you really not in a hurry?"

Guan Zheng leisurely made a cup of tea: "What can you do in a hurry?" All we have to do now is wait for the kidnappers to contact us. ”

Sure enough, it didn't take long for the kidnappers to send the latest news. The fat man in the video is tied to a dark room, his hands are trapped behind his back, the rope around his neck hangs from the roof of the shed, and the most peculiar thing is the sand under his feet. On the surface, the sand kept seeping, making the fat man slowly lose his borrowing point, and the rope around his neck became tighter and tighter. The surrounding situation could not be distinguished, which made the rescue very difficult.

Xiaoquan'er looked at the background of the video and said, "If it goes on like this, the fat man won't last more than three hours." ”

Guan Zheng asked Li Chongyang and said, "Has the source of the video been found?" ”

"Not yet, I can't find it at all, the address is encrypted by multiple layers, and the location is difficult to determine." Li Chongyang said.

Guan Zheng said: "Take it to Guan Nuo and let her continue to investigate." A result must be found. ”

As soon as Li Chongyang got up, Guan Nuo had already arrived. Guan Nuo's smile was still so dazzling, Guan Zheng beckoned and said, "Come and sit down." ”

Guan Nuo was not polite, sat down and said, "I'm here to help." ”

"Has there been progress? Did you find the address? Guan Zheng asked.

Guan Nuo said unhurriedly: "I found it." ”

"Where?" Everyone's eyes were focused on Guan Nuo's body.

Guan Nuo slowly opened his mouth and said, "In Uganda." ”

As soon as Guan Zheng heard about this strange place, he knew that it was not a good result and said: "You were taken into the ditch by others, right?" ”

Guan Nuo said embarrassedly: "What's the matter, I've worked hard, okay?" ”

Guan Zheng patted Guan Nuo's shoulder and said, "I know, I know, what about you, check this new one again, if it's still in Africa, I'll kick you over!" ”

Everyone covered their mouths and laughed. Guan Zheng said loudly: "What are you laughing at? Hurry up and find a way to go. ”

Guan Nuo sat in front of the computer, facing more than a dozen screens, his fingers moving rapidly. Guan Zheng's brain spun like a spinning top, and Xu Jiuyan was still chirping in her ear and asking, "How to deal with the kidnapping case?" ”

Guan Zheng said: "Kidnapping is a criminal act, the process of illegally using violent means against the victim to achieve hostage-taking, usually through this act to achieve extortion, extortion or other conditions or purposes.

The police's approach is to determine the kidnapper's information or location based on the kidnapper's ransom demand or loopholes in the negotiation process, and then successfully rescue the hostage. But the fat man was not so lucky, the kidnapper he encountered was not an ordinary kidnapper, this kidnapper has almost no loopholes, at least we don't see it now. ”

"Then we can't catch it?"

Guan Zheng said: "Of course not. We usually extract the background sound of the video or audio file, isolate and strip it, determine the area where the sound is located, and determine the location of the hostage.

Xu Jiuyan nodded and said, "I know this." But it's strange why didn't the kidnappers give us information, or what they wanted? ”

Guan Zheng continued: "According to common sense, kidnapping must have a purpose, but there are nearly 10 percent of kidnappers who kidnap at random or for the purpose of demonstration. His lack of contact does not mean that they do not have a need, but because they do not have the time. ”

"If you want money, it depends on the time?"

Guan Zheng said: "Of course, in the early days of the kidnapping, the police's thinking was not clear, and the analysis of the environment was indeed very detailed. In the later stages of the kidnapping, both the police and the kidnappers are tired, but experienced kidnappers will choose this time to carry out raids. ”

"The ambient noise is separated." Li Chongyang put out the sound through the loudspeaker, and the office instantly fell silent, and everyone was listening to this sound, including the sound of cars, shouting, and buses. It was chaotic inside, but Guan Zheng also heard something different, and Xu Jiuyan was in a hurry: "Say it quickly, I'm in a hurry." ”

Guan Zheng listed them one by one, there were many buses passing through, and there was a school nearby, because I heard the sound of a whistle. There are also voices of people swarming out.

"The sound of people swarming?"

Guan Zheng nodded and said, "That's right, it could be a subway station, a movie theater, or a train station." This type of place is one with a lot of foot traffic. ”

"Then we are looking for a place where there is at least one school, multiple buses passing by, and it is close to a subway station, a big theater, or a movie theater." ”

"Why don't you hurry up?"

Xu Jiuyan checked the map and asked, "How can you determine the surrounding environment by listening to the background sound?" Especially the sound of the flow of people, which is the strangest thing in it. ”

"Don't understand, do you? This is the simplest Doppler effect. ”
