Chapter 53: Sound Discrimination

"What the hell is going on?" Looking at Ye Yinuo's excited expression, Dong Bingning asked suspiciously.

Ye Yinuo waved his hand and motioned to Dong Bingning not to speak.

"Knock knock~" Two more sounds, Ye Yinuo reached out and touched the coffin lid, adjusted the position of the lid, and then continued to wait for the vehicle to bump.

Next, Ye Yinuo kept adjusting the position of the coffin lid, but he didn't close the coffin lid, but as long as the coffin lid was not completely closed, no matter what position it was, as long as the car had a slight bump, it would make a collision sound with the main body of the coffin.

And this kind of collision sound was not in the dashcam before.

"How could this coffin be sealed?" Ye Yinuo said to himself.

Dong Bingning said a little speechless after hearing this: "Of course it is sealed, and the corpse does not need to breathe." ”

Ye Yinuo continued to say to himself: "During the driving of the hearse, the coffin has been tightly covered, and if it is not covered, it will make this sound. ”

Dong Bingning looked at Ye Yinuo's serious demeanor and asked suspiciously, "Then what?" ”

"To drop the body, you need to open the coffin, and when you open the coffin, there is a sound of wood rubbing, and the sound recorded by the dash cam from beginning to end has no such sound from beginning to end." Ye Yinuo replied.

"That's the weird part." Dong Bingning nodded and said.

Ye Yinuo continued: "If this is the case, then the bag drop should happen before driving. ”

Dong Bingning said: "There is no possibility, the corpse is loaded into the car, and there is a video record, and then the dash cam, and the time connection is very good." ”

"The prisoner's cart and the hearse, which one left first?" Ye Yinuo asked.

Dong Bingning shook his head and said, "I have to ask Team Wang about this, I haven't been exposed to this information." ”

Ye Yinuo took out the phone, and just dialed Wang Han's phone, suddenly there was a "boom~~~", and the hearse rushed into the first tunnel.

Ye Yinuo's body shook violently, the voice just now was also heard in the video, but this voice seemed to have a slight difference.

"Xiaoye, what's the matter?" Wang Han asked.

"No, the sound is not right!" Ye Yinuo directly pressed the phone, he hurriedly walked to the side of the coffin, completely closed the coffin lid, and then supported the coffin lid with both hands, his expression was very serious.

"What are you doing, ......" Before Tang Nianyou finished speaking, she was stopped by Dong Bingning reaching out her hand, she knew that Ye Yinuo could not be disturbed at this time.

Ye Yinuo quietly waited for the moment when the car rushed out of the tunnel.

100 meters

50 meters

10 meters

At the moment when the car rushed out of the tunnel, there was another 'whoosh' sound, Ye Yinuo pushed the coffin lid violently at the same time, and the sound of the coffin lid rubbing against the main body of the coffin overlapped with the movement out of the tunnel, and it was almost completely covered.

Tang Nianyou looked puzzled, not knowing what Ye Yinuo was doing, but Dong Bingning asked in surprise: "In order to prevent the criminals in the coffin from being suffocated, when they came out of the tunnel, someone opened the coffin lid?" ”

Ye Yinuo shook his head and said, "No, the voice is wrong." ”

After he finished speaking, he asked the driver in front of him, "Master, how long is the next tunnel?" ”

"About ten minutes!" The driver replied.

Ye Yinuo nodded, then took out the phone and dialed Wang Han's phone again.

"Xiao Ye, what are you doing?" Wang Han picked up the phone, his tone was a little unhappy.

Ye Yinuo smiled and said, "Team Wang, I just want to ask, after the execution, is the hearse going first or the prisoner car going first?" ”

"After the corpse was loaded, the hearse went first, and then the prisoner cart left, I asked all of this." Wang Han replied.

Ye Yinuo sighed, hung up the phone, he shook his head and said, "No, there must be something wrong." ”

If it is the prisoner cart that goes first, then there is still the possibility of dropping the bag, if it is the hearse that goes first, then there is no possibility of dropping the bag at all, the driver of the hearse has also been examined, and he has also read the confession carefully, there is indeed no time gap, and there is no trace of the time connection.

In this way, during the whole process, no living person was used to wrap up the corpse.

Seeing that Ye Yinuo was still in a state of contemplation, Dong Bingning and Tang Nianyou didn't speak, and a few minutes later, Dong Bingning reminded: "Ye Yinuo, I'm going to enter the tunnel again." ”

Ye Yinuo hummed, continued to close the coffin lid, propped his hands on the coffin lid, and stared at the tunnel in front of him tightly.

With a sound of "boom~~", the hearse rushed into the tunnel, and at the same time, Ye Yinuo pushed the coffin lid open again, making a brief friction sound.

After a few seconds, Ye Yinuo's face was happy, and he said, "The voice is right!" ”

This time it was not only Tang Nianyou, even Dong Bingning was a little confused, she hurriedly asked, "What's going on?" ”

Ye Yinuo made a silent gesture and said, "Wait for another voice." ”

After Ye Yinuo said this, the hearse quieted down, and more than ten minutes passed, the hearse rushed into the last tunnel, Ye Yinuo walked to the other side of the coffin, and when the hearse came out of the tunnel, Ye Yinuo slammed the coffin lid shut.

"That's the voice!" After a few seconds, Ye Yinuo said with some excitement, and his expression relaxed.

Dong Bingning was puzzled all the way and then asked, "What's going on?" ”

Ye Yinuo said: "When the car enters the tunnel, the tunnel is narrow and hesitant, the sound of the tires rubbing against the road, as well as the sound of the motor and the sound of the body because of driving, the echo formed in the tunnel will be relatively large, so it is a 'boom', and after the car drives out of the tunnel, because the terrain suddenly becomes open, the echo cannot keep up, so the noise will be reduced, so it is a 'whoosh'." ”

"And then?" Dong Bingning still didn't understand.

Ye Yinuo continued to explain: "The coffin on this hearse, when opened, because there is a card position, the sound will be relatively loud, so when entering the tunnel, the opening movement will be much smaller, and the sound of closing the coffin lid is relatively small, so when closing the tunnel, it should only be a few minutes away from here to the funeral home, even if the coffin lid is closed, the people inside will not die due to lack of oxygen." ”

"The sound you just said was waiting for the sound you heard in the video?" Dong Bingning asked.

Ye Yinuo nodded and said: "That's right, it's the sound just now, when you enter the tunnel and open it, and when you close it out of the tunnel, it's almost the same as the sound of the three-in, three-out tunnel in the video, and when the coffin is not opened or closed, the sound of entering the tunnel is different, so when I entered the tunnel for the first time, I said that the sound was wrong." ”

"This also shows that every time I enter the tunnel, the coffin has been pushed by someone, and the purpose of the push is to prevent the people inside the coffin from being suffocated?" Dong Bingning also said happily that this is undoubtedly a breakthrough.

Ye Yinuo nodded and said, "That's right." ”

"But the one who followed the car was the second fat of our detachment, and he was not an outsider." Dong Bingning said.

Ye Yinuo chuckled: "I said that the detachment had been infiltrated a long time ago, have you forgotten about this?" Who leaked the previous case? ”

Dong Bingning's expression changed, and he said, "You mean to say that the second fat is an undercover agent?" ”

"Eight or nine is not far from ten!" Ye Yinuo said that if he had said such a thing before, but now that there is evidence, he will not be so scrupulous, at that time, there were only the driver and Er Fat in the hearse, and Er Fat opened and closed the coffin lid three times, and there was only one purpose, that is, he was afraid that the people in the coffin would be suffocated to death.

If it is just to examine the body, it will definitely not be seen when entering the tunnel, and when entering the tunnel, the person's vision will be blind for a short time, even if it is the driver, he will not be able to detect his movements, as for the insignificant abnormal noise, the driver will not care so much.

"Master, you don't have to go any further, you have to trouble us to send us back to the place where we picked us up before." Ye Yinuo said to the driver.

"Okay!" The driver readily agreed, found a place to turn around, and drove to the execution ground.

Ye Yinuo climbed directly to the co-pilot's seat and sat down, he wanted to see the environment along the way, feel the perspective of the driver when he went to the execution ground, and try to find more clues.

……

In the No. 3 interrogation room of the Xicheng detachment, the hearse driver opposite Ju Tianyu had become a little dazed, and after more than an hour of guidance, he had been successfully hypnotized by Ju Tianyu, with a dull expression and a dull look.

Although this driver is just an ordinary person and has not received special training, he has the courage to drive a hearse, and his psychological defense line is not weak, so it took more than an hour for Ju Tianyu to let him enter a state of deep hypnosis.

Ju Tianyu put a metal ball in his pocket and asked, "Yesterday at noon, after you arrived at the execution ground, how many people did you see?" ”

"Five, two armed policemen, two forensic doctors in white coats, and one man in a suit." The driver replied truthfully.

"Who's carrying the body?" Ju Tianyu continued to ask.

"It's me and an armed policeman, and a fat forensic doctor."

"Did the prisoner cart go first or did the hearse go first?" Ju Tianyu opened his mouth and asked, obviously, what Ye Yinuo thought of, he had already thought of.

The driver replied: "After the body was loaded into the car, I drove away first, and the fat forensic doctor followed the car." ”

"Did you stop on this part of the way to the funeral home?" Ju Tianyu asked with some expectation, this is his most important direction, the driver is in this state, there is no possibility of lying at all, if the driver says that he has not stopped the car, it proves that there is a problem with his Ju Tianyu's reconnaissance direction.

"I didn't stop the car, I drove all the way to the funeral home."

The driver's answer made Ju Tianyu frown, in his opinion, there must be a problem during this time period, and he also communicated with the forensic doctor Peng Zicoffin, so that this kind of flawless corpse fraud case could occur, to be exact, the body was dropped by a living person, but the driver really didn't seem to have any problems.

Ju Tianyu didn't give up, he continued to ask, "Did you recognize the fat forensic doctor before?" ”

"I don't know."

The driver's answer made Ju Tianyu stunned, it took so long to hypnotize the driver, and when he interrogated it here, the clue seemed to be broken, which was undoubtedly a resounding slap in the face for him.
