Everyone at the scene was silent......

After Forensic Liu's skills were enhanced, everyone heard the abnormal ending in the last paragraph of the phone.

"Yes...... Is it Yao Gang?" Lu Weiwei turned her head to look at Gu Chen, and asked weakly, "That voice, it's Xiao Zhengtai Yao Gang, right?"

"That's right. Gu Chen looked at Forensic Doctor Liu and continued: "Please forensic Doctor Liu put it again, especially the paragraph at the end, please adjust the speed of speech to 0.5." ”

Forensic Doctor Liu agreed very happily, and directly replayed the original sound enhanced by technology according to Gu Chen's meaning.

In the original sound, Yao Xin's mother called the police in a panic, looking a little overwhelmed, but when she was about to hang up the phone at the end, a little boy's voice suddenly appeared on the police call.

Forensic Doctor Liu, then adjust the speed of speech to 0.2, and the technical enhancement continues. Gu Chen said again.

"Yes. Forensic Doctor Liu also broke out in a cold sweat and seemed to be shocked by this major discovery.

After continuous technical enhancement and the continuous slowing down of the last paragraph, Yao Gang's voice suddenly surfaced.

Everyone heard Yao Gang say: "How did my sister's body ......?"

But before Xiao Zhengtai Yao finished speaking, his mother's phone immediately hung up.

Since Yao Xin's mother had already explained the situation clearly in the police, the operator of the police center only recorded these and began to contact the police force in the jurisdiction.

And the last more vague dialogue is obviously ignored, and it is difficult for normal people to hear what is being said.

"The murderer is Yao Gang, and the accomplice is Yao Gang's mother. Gu Chen suddenly stood up and said his thoughts:

"I remember when we were investigating Yao Xin's disappearance, Yao Xin's mother used to say that Yao Gang had been sleeping in the house when the couple found out that their daughter had disappeared. ”

And when they found the kidnapping letter and called the police, they went to the house to wake up Yao Gang. ”

"That's right, I remember what they said, we have records in the law enforcement camera. Lu Weiwei said.

Gu snapped his fingers: "That's right, the two husbands and wives said this to us in order to avoid their son Yao Gang being involved in the case." ”

"The reason is very simple, the two couples want to create a false impression for us, that is, after the two found out that their daughter was missing, and found a series of operations such as the kidnapping letter and the call to the police, Yao Gang slept in the room until the two couples woke him up. ”

"So their purpose in doing this is nothing more than to exclude their son Yao Gang from the time of the crime, so as to avoid our investigation. ”

Officer Wang also said thoughtfully: "In this way, we heard Yao Gang's voice on the phone just now, which means that Yao Gang didn't sleep at all when Yao Xin's mother called the police. ”

And just when Yao Xin's mother was about to hang up the phone, Yao Gang suddenly traveled and asked his sister Yao Xin's body what to do. ”

Thinking of this, Officer Wang hurriedly asked Forensic Doctor Liu: "The last sentence just now, did it say: How to deal with my sister's body?"

The last two words are not, but that's pretty much what they mean. Forensic doctor Liu said.

Gu Chen also affirmed: "At that time, Yao Xin's mother just called the police, saying that her daughter Yao Xin was kidnapped, but she didn't say the fact that Yao Xin was killed, but at this time, how could Yao Gang mention his sister's body?

Also looking at everyone, Gu Chen said again: "Obviously, Yao Xin was dead at that time, and my brother Yao Gang knew this very well. ”

Because I didn't know what to do with my mother, and I didn't know that my mother was calling the police at the moment, I hurriedly walked into the room and wanted to ask my mother about how to dispose of my sister's body. ”

But I didn't want to, at that time, my mother didn't have time to hang up the police call, but she also saw her son Yao Gang suddenly break in, so she hurriedly hung up the phone. ”

"But at the last moment, we can use technology augmentation to extract accurate clues. ”

"That's right. Lu Weiwei was also overjoyed, and said: "Let's not talk about Yao Xin's mother lying that Yao Gang had been sleeping in the room at that time, Yao Gang's mention of the corpse obviously caught his mother off guard." ”

"Could it be that they could have known the fact of their daughter's death for a long time? This shows that Yao Gang and her mother are seriously suspicious. ”

Gu Chen nodded and said, "And every time Yao Gang answers my question, he has to look at his mother a few times, obviously a little flustered." ”

"Children are not good at lying, but even if they have to lie, and in the presence of adults and in their knowledge, it is very obvious to look at adults, that is a natural reaction, and when I ask other normal questions, Yao Gang will not do this. ”

Lu Weiwei's fists clenched "creaking" at the moment, slammed her fist on the desk, and shouted angrily: "What a ruthless mother and a cold-blooded brother." ”

"Neither of them is a good thing, Yao Xin made so much money for the Yao family, and in the end ended up like this, Yao Xin should not have been born in such a family. ”

Officer Wang also said: "And these people, they also cry and fake mercy, pretending to be quite like that, if we don't find these clues, I'm afraid these people will become fish that have slipped through the net." ”

Seeing that Gu Chen was packing up his equipment and downloading the technology-enhanced audio, Officer Wang hurriedly asked him, "Gu Chen, what are you doing?"

"Before it gets dark, we can't let these wicked people sleep well, and they must be taken to the police station for interrogation. ”

"The Yao family has to be taken away. Lu Weiwei directly took out her mobile phone and said, "I asked He Junchao and them to bring a few police officers over first to control the Yao family, but don't let them continue to play tricks." ”

"Okay, then let's act now, He Junchao is close to them, let them control the scene first, and we will meet in the villa in the western suburbs." Officer Wang said.

Half past five in the afternoon.

Originally, it was the peak hour for major units in Jiangnan City.

But at this time, several police cars were parked in the villa in the western suburbs.

When Gu Chen arrived by car, there were many people around the scene, many of them were pointing and pointing, and scolding came from time to time in the house.

"What's the situation?" Gu Chen was the first to get out of the car, came to an auxiliary police officer on duty on the periphery, and asked him.

"Just this Yao family, they refused to go with us, He Junchao and they wanted to take it away forcibly, but the Yao family began to follow us, called the surrounding relatives and friends, and violently drove our colleagues. The auxiliary police said.

"And now?" asked Lu Weiwei.

"Right now, you're confronting our officers. "The auxiliary police are also a little helpless, mainly because there are too many onlookers at the scene, and the impact is not good.

Officer Wang immediately asked, "Did you act aggressively when you were enforcing the law?"

"Nope. The auxiliary police said very simply, and continued: "We reasoned with them and asked them to assist us in going to the police station to investigate, but as soon as these people heard that they were suspicious, they immediately began to sprinkle, which is a bit difficult to deal with." ”

"You shouldn't say they're suspicious. Officer Wang also said it as an afterthought, and then said helplessly: "But this family is a thief, and it is estimated that they also know that there is such a catastrophe, so the reaction will be so strong." ”

"So what now, everyone is watching?" the auxiliary police officer also looked left and right.

At this moment, many neighbors around are talking to each other, and many people don't understand the situation, but they don't know what is going on inside.

"Let's go in and have a look. Gu Chen said.

"Agreed, I'll go with you. Lu Weiwei didn't say a word, and followed Gu Chen directly inside.

Officer Wang looked around, pointed to a few auxiliary policemen, and said, "You guys are fortunate enough to disperse these people, let them not shoot the video screen, and clear the road at the scene." ”

"Yes. "The auxiliary police received an order, and they contacted several colleagues around them to act together.

In the villa, Yao Xin's parents and Yao Xin's brother are all shrunk in the kitchen at the moment, holding various props in their hands.

He Junchao stood aside with his waist crossed and comforted kindly.

It's not that He Junchao didn't dare to step forward, but Yao Xin's mother put a knife on her neck from time to time and threatened her with death, so He Junchao didn't dare to act rashly.

Seeing Gu Chen, Lu Weiwei and Officer Wang arrive one after another, He Junchao said with relief: "I said why did you come." ”

"What's the situation, Senior Brother?" Gu Chen walked up to him and asked.

"Just these few people, you have also seen, forcing each other to death. He Junchao also sighed and said: "You said, I just summoned them to the Furong Branch for investigation, but I didn't expect the family to react so strongly, and they felt like they had been greatly wronged." ”

"If you don't come again, I guess I won't have a problem, so I'll have to spend it here with them. ”

"But they called a lot of relatives and friends, and they were all outside, in case something happened to them, it was estimated that it might cause a conflict between the police and the people." ”

He Junchao also analyzed the pros and cons of the on-site situation to Gu Chen.

Gu Chen patted He Junchao on the shoulder and said lightly: "Senior Brother He has worked hard, leave the rest to me." ”

"That's what I want. As if relieved, He Junchao turned his head to several auxiliary police officers and said, "Let's retreat and let them solve it in a group." ”

After finishing speaking, the other police officers all evacuated one after another, leaving only Gu Chen, Lu Weiwei and Officer Wang standing there.

"Mr. Yao, Mrs. Yao, do you still know us?" Officer Wang also coughed twice, wanting to walk over to communicate.

As a result, Yao Xin's mother threw a cucumber over, and almost missed Comrade Wang.

"Why are you still smashing people? We are the police in charge of this case?" Officer Wang also said inexplicably.

"Get out!" Yao Xin's mother was the first to shout angrily: "What kind of policeman are you? My daughter's death is unknown, you don't investigate the real murderer, and you say that our family is suspicious, what kind of heart do you have!"

"Yes. Yao Xin's father suddenly said angrily: "Do you think you are so powerful? Now it seems that I am really disappointed in you, what kind of policemen are you." ”

"We ......" Officer Wang was also scolded and bloody, and just wanted to step forward to refute a few more words.

At this time, Gu Chen put his arm on Officer Wang's shoulder and said, "Senior Brother Wang, let's come." ”

"Okay. Seeing that Gu Chen took the initiative to ask for help, Officer Wang no longer insisted.

After all, negotiating with these unreasonable people, tens of thousands of brain cells have to die, and it is naturally best to have Gu Chen come out.

Gu Chen walked forward slowly, his eyes always staring at Xiao Zhengtai Yao Gang.

"You...... Don't come here, you ...... You're coming, I'm ...... I'll die for you. ”

Seeing Gu Chen's indifferent face and not nervous about himself, Yao Xin's mother immediately put the kitchen knife on her neck.

Gu Chen ignored her, walked to a distance of three meters from them, and suddenly stopped.

"Yao Gang. Gu Chen suddenly said.

Xiao Zhengtai Yao Gang frowned, raised his head and asked, "What are you doing?"

"Did you kill my sister?" Gu Chen asked again.

Xiao Zhengtai Yao just gasped, and then looked up at his mother.

Yao Xin's mother immediately retorted: "You...... What are you talking about? How could my son kill his sister at such a young age? Aren't you talking nonsense? You also say that you are a policeman, and I don't think you deserve to be a policeman. ”

Gu Chen still ignored her, but continued to ask Yao Gang, "Yao Gang, answer my question." ”

Xiao Zhengtai Yao Gang was really panicked at this time, he hurriedly hid behind his mother, and looked at Gu Chen with half of his head exposed, his eyes full of fear.

"You didn't sleep at all at noon yesterday, you're eating dragon fruit, aren't you?" Gu Chen suddenly slowed down his tone and spoke to Yao Gang in an communicative tone.

Gu Chen's atmosphere eased, and he suddenly said: "You cut a plate of dragon fruit and were about to enjoy it, when at this time, my sister Yao Xin appeared, and she found that you were eating, so she wanted to eat it too, so she secretly ate a few pieces of dragon fruit in your cut bowl." ”

Speaking of this, Gu Chen was still observing the changes in Yao Gang's eyes, he did not act excessively, as if that was the truth.

So Gu Chen said again: "After that, you warned your sister not to eat, but her sister didn't listen, so you picked up the flashlight and slammed it on your sister's head, right?"

At this moment, Yao Gang, who was still indifferent just now, suddenly became emotional.

Gu Chen found that Yao Gang's hand on the corner of his mother's clothes was obviously deeper.

Mother also noticed Yao Gang's emotional changes, and immediately glared, pointed a knife at Gu Chen, and said, "You...... You policeman, what nonsense are you talking about? Why did my son smash my daughter, you...... You're just talking nonsense......"

"You're also an accomplice. Before Yao Xin's mother finished speaking, Gu Chen's gaze shifted to her at this moment.

Seeing Yao Xin's mother's stunned expression, Gu Chen instantly took a small step forward and continued to ask: "I can tell you that when Yao just smashed Yao Xin's skull, Yao Xin was at most likely brain dead, but according to our forensic identification, Yao Xin died of suffocation. ”

Seeing Yao Xin's mother's stiff face, Gu Chen said again: "This shows that some people want to cover up the truth and think that Yao Xin is dead at this moment." ”

And for the purpose of protecting Yao Gang, he continued to strangle a strangulation mark on the neck of Yao Xin, who was considered dead, but he never expected that Yao Xin was strangled to death like this. ”

"If first aid had been taken at that time, it might have been difficult for Yao Xin to recover to his previous state, but he would not have died immediately. ”

Speaking of this, Gu Chen did not continue, but quietly looked at Yao Xin's parents.

At this moment, Yao Xin's mother was also stunned, as if she had been hit by a huge blow, and looked at Yao Gang with blank eyes.

And Yao Xin's father's face was also ugly, and his body even began to tremble.

"This ...... It's not true, it's certainly not true. ”

"Yao Xin's mother. Gu Chen looked at her again at this moment, and continued: "My son Yao Gang accidentally beat my daughter to a broken skull, and even looked like death, after you found out, I can understand your feelings, but in order to protect your son Yao Gang, you deliberately directed and acted in a good play. ”

"I ......" Yao Xin's mother looked at Gu Chen at the moment, obviously losing the sharpness just now.

"I don't know what to do with this kind of thing. Gu Chen continued to take a small step forward and said lightly: "Because the palms and backs of the hands are full of meat, Yao Xin is your daughter, and Yao Gang is also your son." ”

"You've lost a daughter, but you don't want your son to be stigmatized and affect his future life. ”

"Because Yao Xin is a star of tomorrow, the last person who may become a superstar. ”

"With Yao Xin's current fame, it is enough for your family to eat and drink, and Yao Xin has received the attention and popularity of the business, you are afraid that Yao Xin's accidental death will even lead to a lawsuit by the business. ”

"So you directed and acted on your own, and after making a mark on your daughter's neck, you hid her in a small room in the basement. ”

"Then you set up a fake situation on the spot, and the miscellaneous cracks were mistaken for us to think that there might be an intruder from the window afraid to enter the basement, so you deliberately used a pair of plus-size military boots as cover. ”

Then you go back to the living room and write a kidnapping letter with a text that covers your handwriting. ”

"But because you were afraid of revealing yourself too much, you typed a draft on the manuscript paper until it didn't feel like your handwriting, and then you hurriedly called it. ”

"But you never expected that when you made the call, your son Yao Gang, who had been saying that he was sleeping, appeared, and he asked you what to do with your sister's body. ”

"You panicked and wanted to hang up the phone quickly, but unfortunately, at the last moment, we still caught an important clue. ”

Gu Chen didn't talk nonsense, he directly took out his mobile phone and played the original sound of Yao Xin's mother's alarm phone that he downloaded to her.

The small noise at the last moment suddenly made Yao Xin's mother panic.

However, she quickly calmed down and stammered, "This ...... What does this mean......? I can't hear it well...... Too clear, hard to ...... Is it true that you police want to use this to convict?"

"Don't worry. Gu Chen also knew that Yao Xin's mother would deny it, so he slid to the next audio file and said lightly: "That was the original audio of your police call just now, but this is the audio that has been enhanced by our police technology." ”

"It's the last paragraph you said, that little bit of noise, not only did we increase the technology, but I also slowed down the speed of speech to 0.2, let's listen to it. ”

Gu Chen turned up the volume to the maximum......

At this moment, the most familiar voice sounded again.
