Detective from The Future

The good news is that if the voice of the suspect is recorded, the voice test of the technical department can also determine the identity of the suspect.

The worry is that this is a dash cam for a taxi, which is different from an ordinary private car. You have to drive at least a few hundred kilometers a day. The memory card of the dash cam may not be that big. Two days have passed, and the audio from the night before may have been overwritten.

It's like a person who has been hungry for a few days and suddenly picked up a box lunch, but found out that the box lunch may have expired.

"Master Shen, can your driving recorder save the video from the night before?"

Shen Binlong thought for a while, "I'm not quite sure about this. Generally, the driving recorder is checked immediately after a car accident. Two days have passed. I can't say whether the memory card is enough."

Han Bin said, "Master Shen, if it's convenient, let our colleagues in the technical department check it out."

"Yes, it's nothing. My car is parked in the yard."

Han Bin ordered, "Xiaopeng, call a colleague from the technical department and follow Master Shen."

Twenty minutes later, news came from the technical department that the video from the night before was indeed covered, and it is temporarily impossible to view the video of Lou Hexiang's ride.

However, the technical department will try to restore the video from the night before. As for whether it will succeed, or whether it will destroy the original video, no one knows.

Han Bin's heart can be described as mixed.

...

For the next two days, Han Bin has been paying attention to the situation on the Minxin River salvage team and the technical section, but progress has not been much.

The interrogation against Lou Hexiang has also been delayed.

Although Lou Hexiang's blood shoe prints were found at the scene, Lou Hexiang still had a trace of luck. He felt that the police were trying to blame him. He did not think that shoe prints were as legally effective as fingerprints.

In fact, Han Bin did not blame him, and shoe prints can also be used as evidence.

But the prerequisite is a footprint appraisal certificate issued by an expert from the Criminal Investigation Team of the Provincial Department. Although people in the Municipal Public Security Bureau and Yuhua Branch know that Han Bin is an expert in footprint appraisal, Han Bin has no certificate. Not easy.

But if you want to obtain a footprint appraisal from the Criminal Investigation Team, this process is relatively long, and you have to wait at least a week.

There is no way, everything has to go through procedures, let alone a matter of life and death.

...

December 15th, noon.

On the bank of Minxin River.

Li Hui stood by the river, eating pancakes while looking at Minxin River not far away.

In the past two days, the weather has become colder and the salvage work is also very difficult. Because the Minxin River has low temperature and dim light in the morning and evening, the salvage work is between 11 am and 3 pm, and the salvage cannot be carried out during the rest of the time. This is also the reason why no evidence has been found.

This is an objective natural cause, and it cannot be changed by manpower.

With a sound of "bang...", the salvage crew came to the surface, Li Hui planted the remaining pancakes into his mouth, and rushed over.

The salvager climbed to the shore, turned off the searchlight on his head with his left hand, took off the mask on his hand, and held a backpack in his right hand.

Li Hui walked over quickly, put on his gloves, took the salvager's backpack, took it in his hand and checked it carefully, which was exactly the same as the bag Lou Hexiang was carrying in the video.

Li Hui took a deep breath and opened the backpack, which contained a blue down jacket and a damaged small video camera.

The color of the down jacket was the same as that worn by the suspect, with blood stains on it.

The color, brand, and style of the camera are the same as those lost by Jin Zhiwen.

"This bastard!" Li Hui cursed. There were a lot of small video camera parts in his backpack, but no memory card was found.

The salvage personnel took a breath and asked, "Leader Li, is this backpack evidence of your salvage."

"Yes, it should be discarded by the suspect. Are there any other things below? For example, knives and shoes."

When Han Bin searched Lou Hexiang's home again, he did not find the shoes Lou Hexiang wore when he committed the crime. They should have been disposed of at the same time, and he specifically told Li Hui that shoes are also very important evidence.

"The silt at the bottom of the river is very thick. This bag is easier to find. If it is a knife, it is likely to fall into the silt, making it more difficult to find."

"In this way, you first take a break on the shore, and then salvage it near where you find the backpack to see if you can find other tools of crime."

"Okay." The salvage personnel responded, and the staff on the side wiped him off, and someone came over with a quilt and an electric heater.

The salvage crew rested for a while, ate something, and then went into the water again after half an hour...

...

The next morning.

After Han Bin got enough evidence, Lou Hexiang was tried again.

Interrogation Room of Yuhua Branch Bureau.

This is the second time Lou Hexiang has been arrested. Like last time, he is still sitting on the interrogation chair and biting the nail of his right index finger.

Han Bin sat behind the interrogation table, tidied up the documents, and said after a while, "Lou Hexiang, you have been here for two days, please tell me what you think."

"Comrade police, don't waste time on me, let me go quickly, I'm really innocent."

"Lou Hexiang, since you were arrested this time, I have interrogated you twice, but you refused to confess these two times. There are only three things. This time I sit here with full confidence."

"Hehe." Lou Hexiang smiled, "Then tell me, what evidence do you have? If you are really solid proof, then I don't think I can admit it.

"At eight o'clock in the evening on December 11, you left the China World Trade Center, walked to Jin Zhiwen's house, and then entered his house to kill him, snatched Jin Zhiwen's small camera, and forged the scene of the robbery and murder.

When killing Jin Zhiwen, a lot of blood was on you. To hide the blood on your body, you wore a black woolen coat and took a leather jacket.

Leaving Jin Zhiwen’s house, you walked to Minxin River, throwing tools, small cameras, clothing, and shoes into Minxin River, and then put on a black leather jacket. At this time, you were cold and had not put on shoes. To walk home again, I stopped a taxi at the intersection of Dongan and sent you back to the Guomao District.

Then, you went over the wall and entered the community, threw your black leather jacket into the trash can, and then returned to your home. So after we arrived at your home, we did not find any clues related to the Jin Zhiwen case. "

Lou Hexiang showed a nervous look, biting the nail of his right index finger. He didn't seem to expect Han Bin to feel his whereabouts so clearly.

Han Bin continued, "Since our police dare to arrest you a second time, it shows that we have sufficient evidence."

Han Bin took out a photo of Lou Hexiang's murder that night, "In this photo, although you are dressed very tightly, I can still use professional criminal investigation methods to recognize your identity at a glance."

Han Bin took out another photo, "This is the item we salvaged from the Minxin River, a blue down jacket with blood, and a small camera. There is Jin Zhiwen's blood on the down jacket, and you are on the camera. Fortunately, we salvaged the fingerprints in time. Otherwise, the fingerprints on it might be dissolved by water."

"By the way, we still have a personal ID, that is, the taxi driver you took that night. He installed a dash cam in his car and did not photograph your person, but recorded your voice. Just get the audio file. The appraisal by the technical department is sufficient to prove your identity.

All of the above evidences can form a complete chain of evidence, which you can't rely on. "

Following Han Bin's description, Lou Hexiang's forehead was already covered with sweat, and his face was pale.

Han Bin said earnestly, "Lou Hexiang, you should be very clear about the crime you committed. If you have a good attitude toward confession, you may still have hope of living. If you insist on going your own way, the police can also convict you, but no one can save you. I have you."

Lou Hexiang's complexion changed again and again, he sighed and said helplessly, "I didn't expect that my plan was so rigorous, I was still caught by you! I admit it, I killed Jin Zhiwen."
