The good news is that if the suspect's voice is recorded, the suspect's identity can also be determined after the sound detection of the technical department.

The concern is that this is a taxi dashcam, which is different from ordinary private cars. At least a few hundred kilometers a day, the dashcam's memory card may not be that big, and now that two days have passed, it is likely that the audio from the night before has been overwritten.

It's like a person who has been hungry for a few days and suddenly picks up a boxed lunch, but finds that the boxed lunch may have expired, and it is not certain whether it can be eaten or not.

"Master Shen, can your dash cam save the video of the night before yesterday?"

Shen Binlong thought for a while, "I'm not sure about this, generally this dash cam is checked immediately after a car accident, it's been two days, and I can't say if the memory card is enough." ”

Han Bin said, "Master Shen, if it's convenient, let our colleagues from the technical department test it." ”

"Yes, it's not a problem. My car was parked in the courtyard. ”

Han Bin instructed, "Xiaopeng, you call a colleague from the technical department and follow Master Shen for a trip." ”

Twenty minutes later, news came from the technical department that the video of the night before yesterday was indeed overwritten, and the video of Lou Hexiang's ride could not be viewed for the time being.

However, the technical department will try to restore the video from the previous night, and no one can say whether it will succeed or whether it will destroy the original video.

Han Bin's heart can be described as a mixed blessing.

......

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

The interrogation of Lou Hexiang has also been delayed.

Although Lou Hexiang's bloody shoe prints were found at the scene, Lou Hexiang still held a trace of luck, he felt that the police were tricking him, and he did not think that shoe prints and fingerprints had the same legal effect.

Actually, Han Bin didn't deceive him, and shoe prints can also be used as evidence.

Although the people from the Municipal Public Security Bureau and the Yuhua Branch know that Han Bin is an expert in footprint identification, Han Bin does not have a certificate, so it is not easy to do it at the legal level.

However, if you want to obtain a footprint identification certificate from the Criminal Investigation Corps, the process is relatively long, and it will take at least a week to wait.

There is no way, everything has to go through procedures, not to mention human life.

......

December 15th, noon.

On the banks of the Minxin River.

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

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

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

With a "bang......", the salvage personnel surfaced, and Li Hui planted the remaining pancakes in his mouth and rushed over at a trot.

The salvage crew climbed onto the shore, turned off the searchlight on their heads with their left hand, removed the mask from their hand, and held a backpack in their right hand.

Li Hui walked over quickly, put on gloves, took the backpack of the salvage personnel, and took it in his hand to examine it carefully, which was exactly the same as the bag that Lou Hexiang was carrying in the video.

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

The down jacket was the same color as the one the suspect was wearing, and it was stained with blood.

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

"This bastard!" Li Hui scolded, there were a lot of parts for a small camera in his backpack, and no memory card was found.

The salvage personnel took a breath and asked, "Team Leader Li, is this backpack evidence that you want to salvage?" ”

"Yes, it must have been discarded by the suspect, are there any other things down there, such as knives, shoes, etc. ”

When Han Bin searched Lou Hexiang's house again, he did not find the shoes that Lou Hexiang was wearing when he committed the crime, and he should have disposed of them together, and specially told Li Hui that shoes are also very important evidence.

"The silt at the bottom of the river is very thick, and this bag is relatively easy to find, but if it is a knife, it is likely to fall into the silt, which will be more difficult to find. ”

"In this case, you will rest on the shore for a while, and then salvage it near where you find the backpack to see if you can find any other tools of the crime. ”

"Good. The salvage staff responded, the staff on the side wiped the water on his body, and someone came over with quilts and electric heaters.

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

......

The next morning.

After Han Bin had enough evidence, he interrogated Lou Hexiang again.

Interrogation room of Yuhua Branch.

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

Han Bin sat behind the interrogation table, unhurriedly packed up the documents, and said after a while, "Lou Hexiang, you've been here for two days, tell me what you think." ”

"Comrade policeman, don't waste your 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, and it was only three times, and I am sitting here this time with full certainty. ”

"Huh. Lou Hexiang smiled, "Then tell me, what evidence do you have, if you are really ironclad, then I can't admit it." ”

"At 8 p.m. on December 11, you left the International Trade Community, rushed to Jin Zhiwen's house on foot, then entered his house and killed him, snatched Jin Zhiwen's small video camera, and faked the scene of the robbery and murder.

When you killed Jin Zhiwen, you had a lot of blood on your body. To hide the blood on your body, you wear a black tweed coat and take a leather jacket.

Leaving Jin Zhiwen's house, you walked to the Minxin River, threw the crime tools, small cameras, clothes, and shoes into the Minxin River, and then put on a black leather jacket.

Then, you climbed over the wall and entered the community, threw the black leather jacket into the trash, and then returned to your home, so when we arrived at your house, we did not find any clues related to Jin Zhiwen's 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 for the second time, it means that we have sufficient evidence. ”

Han Bin took out a photo of Lou Hexiang on the night of the murder, "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 video camera, the down jacket has Jin Zhiwen's blood stains, and the camera has your fingerprints on it, fortunately, we salvaged it in time, otherwise, the fingerprints on it are likely to be dissolved by water." ”

"By the way, we also have a witness, that is, the taxi driver you took that night, he installed a dashcam in his car, and he didn't photograph your person, but he recorded your voice, as long as the audio file is taken to the technical department for identification, it is enough to prove your identity.

All of the above evidence can form a complete chain of evidence, and you can't rely on it. ”

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

Han Bin said earnestly, "Lou Hexiang, you should know very well about the crime you committed, if you admit your guilt with a good attitude, maybe there is still hope to live, if you insist on going your own way, the police can also convict you, but no one can save you at that time." ”

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