Fortunately, if the voice of the suspect is recorded, the identity of the suspect can also be determined by the voice detection of the technical department.
The worry is that this is a taxi's dash cam, which is different from ordinary private cars. At least a few hundred kilometers a day, the memory card of the dash cam may not be that big. Now two days have passed, and the audio of the night before yesterday may have been covered.
It's like a person who has been hungry for a few days and suddenly picks up a boxed meal, but finds that the boxed meal may have expired, so it's not sure whether he can eat it or not.
"Master Shen, can your dash cam save the video of the night before yesterday?"
Shen Binlong thought, "I'm not sure. Generally, the dash cam is checked immediately after a car accident. It's been two days. I can't say if the memory card is enough."
Han Bin said, "master Shen, if it's convenient, let our colleagues in the technology department go and have a test."
"Yes, it's nothing. My car is in the yard. "
Han Bin said, "Xiaopeng, call your colleagues in the technology department and follow master Shen."
Twenty minutes later, there was news from the technology department that the video of the night before yesterday was indeed covered, and it was temporarily impossible to view the video of Lou Hexiang's ride.
However, the technology division will try to restore the video of the night before yesterday. As for whether it can succeed or not, no one is sure whether it will destroy the original video.
Han Bin's heart is mixed.
……
Over the next two days, Han Bin has been paying close attention to the situation of the Minxin River salvage team and the technical section, but the progress has been small.
The trial of Lou Hexiang is also slow.
Although Lou Hexiang's blood shoe prints were found at the scene, he still took a chance. He felt that the police were cheating him. He didn't think that shoe prints had the same legal effect as fingerprints.
In fact, Han Bin did not deceive him, shoe prints can also be used as evidence.
But the premise is to have the provincial criminal investigation team experts issued by the footprints appraisal, although the City Public Security Bureau and Yuhua Branch people all know that Han Bin is an expert in footprints appraisal, but Han Bin has no certificate, in the legal level is not easy to use.
However, if you want to obtain the footprint identification certificate from the criminal investigation team, the process is relatively long, and it will take at least a week.
No way, everything has to go through the procedure, let alone the matter of human life.
……
December 15th, noon.
On the riverbank of the people's heart.
Li Hui stood by the river, chewing pancakes, and looking at the popular river not far away.
In the past two days, the weather is getting colder and the salvage work is also very difficult. Because the temperature of Minxin River is low in the morning and evening and the light is dark, the salvage work is between 11 a.m. and 3 p.m., and the salvage work can not be carried out in the rest of the time. This is also the reason why the evidence has not been found.
This is an objective natural reason, and it can not be changed by manpower.
"Bang..." A sound, salvage personnel surfaced, Li Hui will be the rest of the pancake into his mouth, trot past.
The salvage crew climbed up 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 as like as two peas, took gloves, took the backpack of his salvage personnel, and looked them in his hand, exactly as the bag that he had carried on the video.
Li Hui took a deep breath and opened his backpack, which contained a blue down jacket and a damaged small camera. It had been thrown out of shape.
The color of the down jacket was the same as the suspect's, and it was stained with blood.
The color, brand and style of the camera are the same as those lost by Jin Zhiwen.
"The bastard!" Li Hui scolded that there were many small camera parts in his backpack, but no memory card was found.
The salvage personnel gasped and asked, "team leader Li, is this backpack the evidence you want to salvage?"
"Yes, it should be discarded by the suspect. Is there anything else below? Such as knives and shoes. "
When Han Bin searched Lou Hexiang's house again, he didn't find the shoes Lou Hexiang wore when he committed the crime. They should have been disposed of together. He also specially told Li Hui that shoes are also very important evidence.
"The mud at the bottom of the river is very thick. It's easier to find this bag. If it's a knife, it's likely to fall into the mud. It's more difficult to find it."
"In this way, you can have a rest on the shore first, and then salvage it near the backpack to see if you can find other tools."
"Good." Salvage personnel should be a, one side of the staff to wipe the water on his body, and someone came with a quilt and electric heater.
The salvage crew had a rest, had something to eat, and then went into the water again half an hour later
……
The next morning.
After Han Bin had enough evidence, he tried Lou Hexiang again.
Yuhua sub Bureau interrogation room.
This is the second time Lou Hexiang has been arrested. Just like last time, he is still sitting on the interrogation chair biting the fingernail of his right index finger.Han Bin sat at the back of the interrogation table and took no time to collect the documents. After a while, he said, "Lou Hexiang, you've been here for two days. Let's talk about your ideas."
"Comrades of the police, don't waste your time on me. Let me go as soon as possible. I'm really innocent."
"Lou Hexiang, since you were arrested this time, I have interrogated you twice, but you are not willing to confess these two times. It's no more than three things. This time I'm sitting here with full assurance."
"Ha ha." Lou Hexiang said with a smile, "well, you can tell me what evidence you have. If you really have solid evidence, I can't deny it."
"At 8:00 p.m. on December 11, you left the international trade community, walked to Jin Zhiwen's house, and then entered his house to kill him, robbed Jin Zhiwen's small camera, and forged the scene of robbery and murder.
When you killed Jin Zhiwen, you were stained with a lot of blood. In order to cover the blood on your body, you wore a black woollen coat and took a leather jacket.
After leaving Jin Zhiwen's home, you walk to Minxin River and throw the tools, small cameras, clothes and shoes into Minxin River. Then you put on a black leather jacket. At this time, you are very cold and still have no shoes. You can't walk home again. You stop a taxi at the intersection of Dong'an and take you back to the international trade community.
Then, you went over the wall into the community, threw the black leather jacket into the garbage can, and then returned to your home. So when we got to your home, we didn't find any clues related to the case of Jin Zhiwen. "
Lou Hexiang showed a nervous look, biting the fingernail of his right index finger. He didn't seem to expect that Han Bin would touch his whereabouts so clearly.
Han Bin continued, "since our police dare to arrest you for the second time, it shows that we have sufficient evidence."
Han Bin took out a picture of Lou Hexiang on the night of his murder. "In this picture, although you are very well dressed, I can still recognize your identity at a glance with professional criminal investigation means."
Han Bin also took out a photo, "this is the object 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 your fingerprints on the camera. Fortunately, we salvaged it in time, otherwise, the fingerprints on it may be dissolved by water."
"By the way, we also have a witness, that is, the taxi driver you took that night. He installed a tachograph in his car. He didn't record your person, but recorded your voice. As long as you take the audio file to the technical department for identification, it is enough to prove your identity.
All the above evidence can form a complete chain of evidence, which you can't rely on. "
With Han Bin's description, Lou Hexiang's forehead has been covered with sweat, and his face is pale.
Han Bin said earnestly, "Lou Hexiang, you should be very clear about the crime you committed. If you have a good attitude towards confession, you may still have the hope to live. If you insist on 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, "I didn't expect that I was caught by you because of my strict plan! I admit it. I killed Jin Zhiwen. "
