"Detachment leader, can you tell Lin Ziyang's mother what she said to Lu Bin in detail?" Zeng Jinling kept thinking calmly.

Lin Ziyang's mother said that the man knelt in front of Lin Ziyang's portrait and cried bitterly, saying that when the three bastards killed Lin Ziyang, he had called the police, but the police ignored him, and if the police could have arrived in time at that time, Lin Ziyang would not have died......

Wei Chihong paused suddenly, and his dark thoughts were brightened by the firelight. If the police could have arrived in time, Lin Ziyang would not have died, "Police? He also has a strong hatred for the police, and the fourth person is the police! ”

"Yes, police." Zeng Jinling nodded in agreement, "The purpose of the prisoner is to avenge Lin Ziyang, and he also has hatred for the policemen who did nothing back then and didn't save him when he saw death." He must have thought that Qiao Yan was a policeman, so he arrested her. ”

Yu Chihong suddenly remembered the bouquet of yellow chrysanthemums in front of Lin Ziyang's tombstone, that person had been following them, from the cemetery to the new life square, and finally found an opportunity and robbed Qiao Yan! He pressed his forehead with his hand and closed his eyes, feeling heavy and bitter.

The bouquet of yellow chrysanthemums, Cao Chongshan failed to get any useful information after the inspection, and the person who offered the flowers was very cautious, and even left no fingerprints, but this further confirmed Wei Chihong's guess that the person who placed the yellow chrysanthemum in front of Lin Ziyang's tombstone was the murderer of the serial murder case!

The task force also quickly intervened in the investigation, and Lu Bin took someone to look up the surveillance video of the New Life Plaza, but the screen only showed that Qiao Yan walked into the passage to the underground garage while answering the mobile phone. Surveillance footage at the exit of the garage captured a Spirra-N Spirra-N compact sedan at the same time and is currently being traced.

"A strange video has appeared on the Internet." Wan Xing suddenly shouted.

Everyone else gathered in front of her computer screen. Looking closely, everyone was stunned. Qiao Yan appears in the picture, in a dimly lit room, chained to a chair. This is a live broadcast, and the video is accompanied by caption: A female policeman from the Haidu City Public Security Bureau was kidnapped, but the Public Security Bureau was unable to rescue her, so everyone came to despise the incompetent police!

Qiao Yan lowered her head and did not move, unable to see her face clearly.

Yu Chihong stared at the screen, his eyebrows were horribly knotted, and his eyes were red.

The lower right side of the screen flashed, Wanxing's computer was installed with VoIP software, and someone dialed the VoIP phone.

"I'll pick it up, and you track down the call." Wei Chihong confessed to Wanxing.

He clicked "connect" with the mouse. "Hey—"

"It's Mr. Wei Chihong." The man's deep voice was particularly frightening in the silent night, "Is the video good?" ”

"Who are you?" Wei Chihong tried his best to control his anger.

The man's words were contemptuous. "I am a messenger of justice, and my duty is to denounce the incompetence of the police. I've been following you all day, and your every move is in my eyes, it's funny. ”

"Is it justice to kidnap an innocent person?" Wei Chihong asked.

"What I want is a social sensation, and the kidnapping of the police is the most sensational." The man snorted, "Besides, I hate people like you who put up a police stand and hang around all day. The case was not investigated, and I still had the leisure to go to the mall and buy gifts. ”

"How is Qiao Yan?" Wei Chihong's tone became uncontrollably hurried.

"I'm not going to kill her yet, I'll give you 12 hours." The man defiantly, "If you can't find us before 12 noon tomorrow, then wait to send her to the crematorium." Come on! ”

Before Wei Chihong could respond, the man had already hung up the phone.

Wanxing cursed, "Damn." "This VoIP phone, like the published video, is through a foreign server, and the IP address cannot be found. It's too cunning. ”

"As soon as this video was posted on the Internet, even people abroad could see it." Zeng Jinling sighed heavily, "He's trying to make everyone come to see the joke of the Public Security Bureau." ”

Wei Chihong's face turned pale, he clenched his fists, and said with an oath: "Qiao Yan will definitely be rescued safely, and the prisoner will also be arrested!" ”

Lu Xipeng hugged his wife Xin Qiyun and was sleeping soundly. The phone vibrated for a long time before he finally woke up from his sleep.

"Who, call in the middle of the night." Xin Qiyun was also woken up, muttering that she couldn't open her eyes.

Lu Xipeng answered the phone with sleepy eyes.

"Professor Lu, I'm sorry to disturb you in the middle of the night." Wei Chihong said apologetically, "There has been a very serious kidnapping case, so I can only trouble you to come to the Public Security Bureau immediately." ”

Lu Xipeng's sleepiness was immediately driven away, and he quickly got up and dressed.

"What's wrong?" Xin Qiyun also sat up.

"The people from the Public Security Bureau were kidnapped, and Wei Chihong asked me to listen to the prisoner's voice." Lu Xipeng dressed as quickly as he could.

"People from the Public Security Bureau were kidnapped?" Xin Qiyun was surprised, and her consciousness was much clearer.

Lu Xipeng leaned down and kissed her face. "Baby, don't worry about it, you go back to sleep, and I'll report back to you in detail when I get back."

"Oh, then be careful." After Xin Qijun kissed him goodbye, she sat on the bed and thought for a while in a daze before lying down again.

The sound of the prisoner talking to Wei Chihong was recorded. Lu Xipeng first eliminated the suspect's voice, and then separated the sound sources of the surrounding sounds one by one, comparing the frequency number with the database, and the sound of the waves hitting the rock wall could be heard.

"It's close to the sea." Wei Chihong said, but Haidu is originally a coastal city, and there are too many places near the sea.

"The characteristic voice is this." Lu Xipeng continued to analyze, "It's a very low frequency number, it's about the same as a phone call, it's very small. What could it be? He couldn't think of it, and said that he could only take a weekly wave odometry to look for it on the coast and check all the places where there was this cycle, but there was not enough time.

"Is there any other way?" Yu Chihong asked.

Lu Xipeng told Wei Chihong that he happened to participate in the development of a sound camera, that is, a camera that visualizes the sound source and frequency with color. If you take pictures with this camera, a variety of colors will be displayed depending on the source of the sound and the number of cycles.

The camera was at the manufacturer's place, and he immediately got in touch with the person in charge.

Wei Chihong also asked if he could judge the height characteristics of the prisoner based on his voice. Lu Xipeng said yes, but he had to set off immediately to get the sound camera, which was far away from the Public Security Bureau, and it would take a lot of time to go back and forth.

"Let me try, I've learned a little bit too." Wanxing took the initiative to ask.

Wei Chihong saw the confidence in her eyes, so he gave her this task with confidence.

Wan Xing listened to the recording repeatedly, analyzed the prisoner's voice, and finally came to the conclusion that the prisoner was between 1.82 and 1.85 meters tall and 20 to 30 years old. Wei Chihong sent this information to all investigators.

"Boss, I've found the prisoner's car." "The car was abandoned near the ferry terminal, and a young man with a large wooden box was seen on a fisherman's fishing boat. The man was very tall, at least 1.8 meters tall, and looked to be in his twenties, very athletic, and his age and appearance matched the characteristics of the prisoner. I suspect that he stunned Qiao Yan and put it in a box and took him to Chase Wave Island. The pier where the fisherman's boat docked was not monitored, and his whereabouts could not be traced. ”

Wave Island! Places close to the sea! Wei Chihong's chaotic thoughts instantly became clear, and he asked Lu Bin to bring the witnesses to the public security bureau to make a mock portrait of the prisoner.

"That man has a square face, slender eyes, and looks quite fierce...... Wei Chihong repeatedly asked the witnesses about the details, according to the eyewitness's description and his own understanding of the human body's appearance, body shape and the environment at that time, he gave full play to his own painting expertise, combined with the use of portrait combination portrait software, through the method of artificial simulation portrait as the mainstay, supplemented by computer portrait, it took nearly two hours to finally complete the dynamic portrait of the prisoner, even the body and clothes were simulated.

"That's him, it's exactly the same!" Eyewitnesses marveled.

Lu Bin was also very impressed. "Boss, I really didn't expect that you still have this hand, tell me, how did you do it?"

Wei Chihong was already very tired, but seeing that Lu Bin humbly asked for advice, he still made a general introduction: "Everyone can be divided into eight types according to their face shapes. The national character face with big ears, the round face with a round head and a round brain, the diamond-shaped face with two pointed ends, and if subdivided, there are also 'A' shaped faces, 'by' shaped faces, 'Shen' character faces, etc. With such a classification, even in the face of an eyewitness whose description is illogical, he can gradually be directed to the correct method of description. ”

With the portrait, there are clues to follow, and Lu Bin immediately led people to devote themselves to the investigation of the identity of the prisoner.

It was close to half past seven in the morning, and all those involved in the investigation had a sleepless night.

The task force convened an emergency meeting. Fu Yiming threw out several copies of today's newspaper and complained. "Look at it, all the media have published the news of the kidnapping of public security officers, and all kinds of news on the Internet are overwhelming, it's really embarrassing to go home!"

"Shame is not the point." Yu Chihong was a little angry.

Fu Yiming's words were tingling. "The person was kidnapped when he was with you, the captain of the dignified detachment, he is not even capable of protecting a subordinate, what is the key to talking about the problem!"

"Well, now is not the time to hold accountable." Li Haoxun walked in, "There are only more than four hours left until 12 noon, hurry up and rescue people." First of all, ensure Qiao Yan's safety, and everything else must be based on this premise! ”
