Chapter 675: Stirring up the Situation

Chapter 675: Stirring up the whole situation

Tao Lu and others were even more excited when they heard that paint had been found.

Tao Lu was a criminal police officer and did not know much about criminal science, but he knew one thing: whenever there was paint evidence in the inspection materials, the laboratory would basically not fail, and would give some explanation, and the court would also accept it very widely.

This is because paint evidence is extremely widely used, the most common of which is car paint. In road traffic accident cases, vehicle paint evidence is often used to lock the suspect vehicle and determine whether the collision played a key role. In addition, marine paint, construction paint, spray paint, etc., also frequently appear in cases.

The complex composition of paint may be a problem in industry, but it is very useful in criminal identification. There are even more outrageous inspection methods, such as microscopic inspection, infrared spectroscopy, Raman spectroscopy, scanning electron microscopy, X-ray energy spectrum, X-ray fluorescence spectroscopy, Py-GC/MS inspection-if the loyalty of officials could be detected by so many technologies, integrity would have become a basic exercise long ago.

The police station's own trace evidence laboratory did not dare to neglect it and worked overtime to help jump the queue.

In just one day, the inspection report was delivered to Tao Lu's desk.

Tao Lu quickly flipped through the inspection report, with a triumphant smile on his face.

The members of the special task force who heard the news immediately filled Tao Lu's office.

The director of the inspection center smiled and passed the report to everyone, and explained on their behalf: "The white particles are indeed paint, and they come from Futian's micro-car. We used a variety of methods to verify it. The report uses the most mature infrared spectrometer to do the test. It can be seen that there is an absorption peak of 1724 in the sample, and there are also absorption peaks of 1601 and 1583..."

Several senior criminal police nodded "hmm", as if they were responding to their wives, and did not listen to what the director said with great effort. At the same time, they stretched their necks to read the report one by one, as if they understood it.

The director of the inspection center suddenly looked resentful: "I've told you the final conclusion..."

"For a light truck, should we check the vehicle's driving trajectory first? To be on the safe side, should we visit nearby residents? This type of vehicle is still very conspicuous in residential areas." Cui Qishan read the report and became emotional: "It's just that the time span is relatively large, but it shouldn't be a problem."

In the current police system, as long as the vehicle's license plate is entered, its driving trajectory for a long period of time can be seen. Of course, this driving trajectory is mainly completed by monitoring, which is an application of big data, eliminating the trouble of criminal police blindly following the car.

Even if the vehicle blocks the license plate, etc., the police can also find its trajectory through fuzzy search.

Liu Sheng next to him said: "We should be able to find similar cars passing by nearby. I don't know how many there are, but it won't be much work to search one by one."

"There is a problem. The paint of a van on the body does not mean that the van must be driven to the open space. It is possible that the van is the first scene, the open space is the place where the body is dumped, and other means of transportation are used in between."

This sentence is the key, which has aroused the enthusiasm of several criminal police officers.

Tao Lu turned his head and took a look, but saw that the person who poured cold water on him was Xiao Si from Cui Qishan's new task force.

Liu Jinghui coughed twice and said, "It is indeed possible that the van was parked in other places, but I think it is very likely that it was driven to an open space. Otherwise, the transportation of six bodies would be a huge trouble. Even if the murderer did not understand it at first, he would give up this method after transporting the bodies once or twice."

"Mini trucks are generally three meters or three meters and two meters long. They cannot be driven to many places in the city. They cannot be driven to the open space here, at least during the day. Driving here at night, it is not very convenient and conspicuous in the dark." Xiao Si has invested a lot of time in this case and has his own ideas. He will not be easily convinced.

Liu Jinghui considered his words, smiled, and said, "It is true that this factor cannot be completely ruled out, but it is not easy to move the body. When the victim just died, the body was very heavy, so the murderer had to dismember it. Everyone has seen how dirty a rotten body is. Even if the bones are white, there are often things attached to them. In this case, the murderer is making it more difficult to move the car."

"And there will be a lot of evidence left in the car, and it will be difficult to clean it." Tao Lu nodded to Liu Jinghui and said, "Let's not consider the issue of transportation first. Liu, please continue. Oh, Jiang Yuan is here, Captain Jiang is sitting here."

He was denying Xiao Si's idea.

Tao Lu smiled from the bottom of his heart when he saw Jiang Yuan. The case was about to be solved, but it was all Jiang Yuan's credit.

As a criminal policeman, he could find out the situation at the scene after asking a series of questions. And the young forensic doctors present had already excitedly described Jiang Yuan's discovery experience again and again.

If this case is solved, this scene will be talked about for a long time.

Jiang Yuan smiled and greeted, but did not sit over. He just said: "I have read the electronic version of the report, you continue."

Before anyone else could speak, Xiao Si did not give up and said: "I admit that the probability of replacing the vehicle is not high, but we must take this situation into consideration. In addition, the paint we found should not be the exterior paint of the vehicle, but Interior paint. If so, could the murderer just use Foton's paint to touch up the paint? I don't mean to be disrespectful, but the price of Foton cars is relatively low, and the repair shop uses their paint to spray other cars. It’s possible.”

Tao Lu and others frowned.

If Xiao Si was to argue, what he said made sense and had to be taken into consideration.

Liu Jinghui waited for a while and said: "The core breakthrough point now is this car. Is it a Foton brand van? I think you can search for Foton brand first, and check everything that passes through the open space in the driving trajectory. If it is still No, then consider the situation Xiao Si said."

When he explained this, everyone's thinking instantly became clear.

Cui Qishan grabbed Xiao Si and said with a smile, "You almost led me into a ditch."

Xiao Si spread his hands and did not press for approval.

Liu Jinghui coughed twice more and said, "I have another trick here, you can try it."

Tao Lu looked over immediately. It was true that there was no upper limit on the budget for this case. It was also true that he felt guilty because he had no money in his pocket. The trick was particularly suitable for him.

Liu Jinghui continued: "I thought of it when I was reading the transcript. Several residents near the open space here reported and called the police very frequently. In addition, because they wanted to demolish, they had no control over these construction vehicles, trucks, etc. , are also very sensitive, and are often mentioned in the police records. Maybe you can check and compare the records from two years ago, maybe there is a license plate number. "

Tao Lu patted his thigh, turned around and said, "Old Liu, I leave this to you."

Liu Sheng responded quickly. This method is affordable and cost-effective. Just send two people to check the records, and it might become a breakthrough in the case. It's like a gift from heaven. Even if it can't be found, it actually doesn't matter. The workload of two people is nothing.

Cui Qishan wanted to raise his hand but didn't have time until he left the door. He still felt a little regretful and said to Xiao Si: "You just shouted yourself. They are all captains and the like. They are embarrassed to argue with you. I can't argue." It doesn’t matter, Tao Zhi doesn’t like you anyway.”

Xiao Si shook his head and said: "I'm the shit stirrer in the shit group. How can I be allowed to touch this kind of cake?"

Cui Qishan was stunned for a moment, stared at Xiao Si for a long time, and said: "If it really is a shit stick, you can't stir it up."
