Chapter 1191 Difficulty

"I'll take another turn."

Jiang Yuan said that he returned to the crime scene and examined it.

Soon, Jiang Yuan stood in front of the broken glass and looked at it bit by bit.

In order to confirm whether the materials in the warehouse were really lost, the warehouse administrator called in many people, so that the warehouse was full of footprints, so many that they were unusable.

The only thing that was well preserved was this piece of broken glass.

Even if the people in this factory had not thought about protecting the crime scene, this place was the least damaged due to the presence of broken glass - it was still damaged a lot, but not too badly.

Based on the footprint analysis, Jiang Yuan quickly came to a conclusion: there are people who are not afraid of pricking their feet and standing on broken glass! Some people can even break glass under their feet!

In this way, the position of the broken glass was moved.

Then, based on the location and size of the broken glass, it becomes very difficult to judge the action and force when smashing the glass, and even the intention of breaking the tool.

Liu Jinghui saw Jiang Yuan standing there for a long time, and felt that his dragon was preparing to exhale, so he came over and asked, "How? Can you tell the height and weight of the criminal? What tools were used?"

"I can't tell." Jiang Yuan answered seriously. He really wanted to see it, but he only saw the enthusiasm of the crowd and the strength of his feet.

"What a pity." Liu Jinghui smacked his lips: "If the list of personnel could be screened by height and weight, the workload would be much smaller. It would be okay to have a rough range."

"It's useless. The criminal knocked on the glass several times. Look at the stubble on the glass next to the window. The people coming from behind also kicked the broken glass away. However, the criminal must have climbed in through the window. The window There are scratches on the sides too.”

The criminal broke in through the window, so it was ruled out that he had a key and pretended to break in. It was a bit of a gain.

"It seems that we can't directly kill the general and capture the flag." Liu Jinghui regretted.

"Let's go out and take a look." Jiang Yuan had already walked around the warehouse twice before going out and walking around the factory area.

The factory has stopped working today, but the workers did not take a holiday. They were walking around the factory in twos and threes, and some organized people to do some chores.

It can be seen that the factory director is very reluctant to stop work. But highly toxic chemicals are controlled, and if they are lost, they must be reported. Otherwise, he might not report them at all.

The factory is very small, and the factory area is even smaller. It has no appearance of a traditional large state-owned enterprise factory. Including the production equipment, there is no trace of modernity at all, and there are traces of simplicity everywhere.

Although the factory's products include highly toxic compounds, where the factory's investment, profits and management capabilities are placed, what everyone sees at this moment is what they can maintain in the long term.

The factory director is an old businessman in his 50s. He is the type who was forced to go into business. He does not have very strong management capabilities. He barely maintains the factory and makes money by taking advantage of some opportunities in his early years. They were all put into the factory, and after more than 20 years, they owned a factory worth tens of millions of yuan, as well as tens of millions of yuan in loans. They were considered to be living a pretty good life as a small factory owner.

His middle-level cadres include peers who have conquered the world together, as well as several junior college students who were recruited later. At that time, private factories could not recruit serious undergraduates. Unlike now, some of the workers who came to work were college graduates, but there were no management positions left for them.

Jiang Yuan walked around the factory twice, finally looked in front of the gate, and finally left the factory and walked along the road.

"Are you looking for surveillance?" Liu Jinghui knew what Jiang Yuan was thinking at a glance.

Jiang Yuan nodded and said: "The surveillance in the factory is useless. The surveillance in the warehouse is broken. The surveillance in the factory is also outdated. You can't see anything at night, and the layout is not good... Let's expand the scope and take a look. ”

"It's also a way. However, this is the connection line between the national highway and the expressway. There are too many cars passing by. How to determine the vehicle that committed the crime..." Liu Jinghui said and raised his hand: "The vehicle that committed the crime should not be on the expressway. That would be too much." It’s troublesome, and you have to be photographed and recorded when you get on and off the expressway, and when you pass through the toll booth.”

Liu Jinghui moved his hand on the road in front of him and said, "The criminal should have driven over, stopped to load the goods, and then turned around and returned?"

Liu Jinghui's eyes lit up when he said this, and the dragon knight's belief made him seem to be glowing: "This must be right. You can look for a suitable place in front of you to turn around, see if there is surveillance, and then look for the incident. I think there should be clues about the vehicle that turned around that day.”

"That makes sense." Jiang Yuan nodded in agreement.

"This level of reasoning is trivial." Liu Jinghui recalled that he often assigned tasks to technical staff in the past, and he felt inexplicably like regaining his glory.

Jiang Yuan just smiled and continued walking along the road.

There are many surveillance cameras on one road, but there can be very few surveillance videos on the same road.

Jiang Yuan walked forward for more than a kilometer and said, "It's almost there. Let's see how far we can collect it."

Along the way, there are many places where you can turn around, but not every location has a camera.

But I can't care about that much now. I took the video back first so that there would be room for further discussion.

The Changyang Municipal Bureau's own picture detective was used.

Please...you...collect 6...books...!

The image detectives who were investigating the academician case just now under Jiang Yuan's command were now mobilized to investigate dangerous chemicals, and they were a little dazed for a while.

A small number of image detectives were sent to collect surveillance videos, and the rest began to read the surveillance videos that had been collected.

Changyang Municipal Bureau's own case also had time demands, so Jiang Yuan arranged two teams and more than 40 people to watch the videos at the beginning.

Wei Shijian, who was left in the command room looking at mathematics stupidly, quickly joined in, pretending to be doing joint research, and also watched the videos together.

What was a little surprising was that the task arranged by Jiang Yuan did not take too long. It can even be said that when many image detective police officers had not yet entered the state, a suspicious vehicle appeared in the surveillance video at the door of a car repair shop 300 meters away from the scene.

"The surveillance at the entrance of the repair shop is mainly aimed at their own garage door, but we can see that a car is circling and turning around in front of the garage door."

"The car drove through the company wall at 4:10 in the morning, but did not turn around until 4:50. This period of time just matches the time when the suspect committed the crime."

"The problem is that the light is insufficient. Not only did we not take a picture of the vehicle's license plate, but we couldn't even see the characteristics of the vehicle."

"Next, we will adjust our focus to determine the vehicle information..."

The captain of the image detection team quickly reported the information and began to assign tasks to himself. In such a short time, it is easy to gain confidence to be able to obtain so many clues!

Liu Jinghui was also full of expectations.

Then...

Time seemed to stop, and no new clues appeared.

This connecting line connects the national highway and the expressway. Most of the vehicles coming and going are from other places and provinces. It is very slow to check one by one. There is no vehicle checkpoint on the connecting line itself. For a while, even the shadow of the suspicious vehicle was not found.
