Chapter 1123 Hard Work
After Jiang Yuan walked a long circle in the park, he walked along several roads outside the park.
Qiu Li insisted on following. When her legs became weak from walking straight and she instinctively wanted to give up, she saw the female doctoral student with long black hair next to her still walking briskly, and she regained her strength.
Walking to the back, Qiu Li began to feel happy. Since she passed the civil service exam, she basically couldn't feel the joy of working hard and breaking through herself.
Sometimes, when you have been free for a long time, with no shortage of money and no burden, you can eat whatever you want, play whatever you want, and go wherever you want... After that, even if you just find a direction to work towards, it seems precious.
"Almost done." Jiang Yuan looked around and asked the criminal police from Luojin City Bureau to help collect the surveillance video.
There are quite a few surveillance cameras in the surrounding area. Those built by public institutions with approval only need to be coordinated, but there are actually more private cameras. Among them, the cameras in shops, shopping malls, parking lots, and various public and private units are relatively well-known. Other cameras such as trams or private residences are much more difficult to find, but they are all cameras and should be equal.
The most important thing, of course, is that the task force has sufficient manpower to fight this kind of lucrative battle.
Watching other police officers searching every store along the street, Jiang Yuan turned to Pang Jidong and said, "Let's go to the Image Detective Squadron first and send the collected videos over to synchronize them to see if we can find the vehicle that the murderer used to transport the body."
At the film and television city, moving the corpse for hundreds of meters was already an exaggeration. Moving the corpse out of the park here would be too tiring. It is an impossible task in terms of manpower alone, so transportation is necessary.
A criminal police officer who came with Pang Jidong also followed along the way and couldn't help but say, "It doesn't necessarily mean they're transporting corpses. If the victim is threatened, they might follow the murderer out. In that case, they would have more routes to choose from..."
"Impossible." Jiang Yuan denied it immediately, and then he felt his tone was a little stiff, and said: "The pollen on the victim's body is also layered. For example, a large amount of clover pollen and the corresponding pollen map indicate that he happened in this park. If he can have normal contact with the outside world, he should have more pollen of other species on his body..."
Jiang Yuan reorganized his words to explain, and said: "Based on the pollen on the victim, it is basically certain that he was killed in the park and was carried out."
"Then you can find people who often come to the park and see if they have seen anyone being carried or backed." Pang Jiedong took over the conversation and gave a suggestion that was not really a suggestion.
Jiang Yuan nodded: "You can ask. Let's go to the Image Reconnaissance Team first."
There is a lot of uncertainty in interviews, and many cases are solved through interviews. This skill belongs to criminal police skills, and there is definitely no problem in continuing to do it.
However, even if the suspected target is visited, the follow-up cooperation of criminal science technicians is still needed. For example, if the murderer is identified through the surveillance cameras in the park, if the murderer avoids the surveillance cameras in the park throughout the process, then a criminal sketch may be needed to draw the murderer's appearance.
Alternatively, reducing the workload of criminal police through interviews, for example, determining the murderer's whereabouts and knowing which direction he went, may be more conducive to the investigation.
However, given the current abundance of resources, the task force does not actually have a strong demand in this regard.
In other words, even if some information can be obtained by visiting the elderly people walking in the park or dog owners, the task force still prefers a more complete investigation.
As for Jiang Yuan alone, although the cameras in the park are not good, the vehicle checkpoints outside the park are complete.
This means that any vehicle leaving the park will basically be captured by the camera.
This is basically the configuration of most provincial capital cities today.
People don't have to take the usual roads. There are only so many lanes. If there are image detection teams, they can just tidy up the cameras in the city without adding too much cost. Then they can just take pictures. With the current level of technology, the storage cost has long been ignored by the police.
Jiang Yuan gave the order, Mu Zhiyang hummed twice into the intercom, and soon a Coaster stopped over.
Jiang Yuan and others got on the car one after another, and Qiu Li hurriedly followed.
Mu Zhiyang was stunned for a moment, stretched out his hand to block the car door, and said: "You are from the park management office, so you don't have to follow us."
Qiao Shengli in the car smiled slightly and gently shook her long straight black hair with her hand.
Qiu Li felt like her chest was about to explode. She was so excited that she said, "Don't you want to see the surveillance video around the park? I am very familiar with the area around the park. I often walk on the roads here, and I also participated in the renovation of the city management department..."
The latter qualification made Jiang Yuan raise his eyebrows: "Let her come up."
Jiang Yuan expressed his agreement, and naturally the others didn't say much.
Luojin City Image Detective Brigade.
On the large screen in front and the small screen below, dozens of surveillance videos were playing simultaneously. Jiang Yuan...
Jiang Yuan naturally couldn't keep up.
But the biggest difference between police and criminals is that there are more of them.
Even a police officer like Jiang Yuan, whose skills can crush others if he acts alone, would not really act alone. In fact, Jiang Yuan's basic configuration for solving a case now is already a team of more than 30 people who graduated from a special police school with more than five years of experience, a dozen Ningtai County native veteran criminal police, a criminal police team of about 20 people in the local area where the case occurred, and the criminal science and technology centers of the two places.
And this is just the standing force. When necessary, Jiang Yuan will often mobilize hundreds of regular police forces and armed spearmen. At the same time, the vehicles and even business jets assigned to these personnel are difficult to calculate the cost.
Even for Liu Jinghui, who is most particular about fighting wits and courage, it is basic training for him to go out with a criminal police team.
Jiang Yuan will not be polite to the criminal suspect now.
All the police officers of the Image Detective Brigade who are at home have been assigned one or several screens and are working hard to read.
In fact, there are many skills to watch surveillance videos, especially wide-angle surveillance. The distortion of people in different positions will increase, and it takes some time to get used to it before you can better identify it.
Jiang Yuan kept participating in the video synchronization.
This is the more troublesome part of image detection. The range of one camera is limited, but the other camera may not be able to connect seamlessly. In other words, even if it can be connected seamlessly, it still takes a little thought to accurately transfer from one camera to another.
There is no help from a film editor here, and many of the image changes seem to have been montaged.
The detectives from the Image Detective Squad hoped to see a scene where the murderer or murderers came out carrying or hiding Zhang Lei's body. However, after watching the surveillance footage for several hours after Zhang Lei appeared, no one found such an image.
Everyone's eyes turned to Jiang Yuan.
"From the time point of view, the murderer killed Zhang Lei and drove to Lanyue City without stopping. It should have taken about a day on the road. However, according to the investigation in Lanyue City, there are not many cars from Baijiang Province that have arrived there." Jiang Yuan looked at Liu Jinghui and said, "In this case, the murderer may have changed cars?"
"It's also possible that the license plate was changed." Liu Jinghui said: "It's more convenient to use a fake license plate. You don't have to move the body. In addition, you always need a car to change the car, so you need to prepare it in advance, which is a little troublesome."
"If the license plate is well-forged, even if it is your own car's license plate, it will be basically impossible to investigate." The captain of the Image Detective Team said. The Image Detective Team also often handles cases in this area and has rich experience.
Liu Jinghui nodded: "Then do the hard work, just look at the model and color, not the license plate, and see how many cars overlap between the Lanyue Film and Television City and the Luojin City Park. Well, you can even ignore the color and just look at the model..."
"Then there are a lot of overlaps." The captain of the image detection team counted on his fingers and said, "The three big cars on the road are the Japanese Accord, Camry, Teana, Sagitar, Bora, Passat... Oh, and Wuling Hongguang... There are only so many models on the surface. If you want to identify the specific generations of these cars with nesting doll faces, the workload is too heavy... Otherwise, scan the software first and see if it can jump out directly."
"You can also scan it with the software." Liu Jinghui did not completely deny it.
There are many types of image detection software, but they are all based on reading images, so the accuracy rate is never very high. They are more than enough for general public security management, but it is disturbing to use them to solve murders like this.
Jiang Yuan looked at the constantly changing surveillance video in front of him and said slowly: "Since we are talking about hard work, how about this? After Zhang Lei appears, all the vehicles that appeared in the surrounding area within 12 hours are pulled out to see if any of them have left the city. The murderer killed someone, so he would not change the car if he already has a means of transportation."
"That's not necessarily true." Liu Jinghui objected, and said seriously: "Maybe he was driving an electric car when he killed someone. It's also possible that he changed to a gasoline car to drive on the highway."
Qiu Li was listening with eyes wide open. Seeing Liu Jinghui refutate Jiang Yuan, she couldn't help but said, "This won't work, and that won't work. You have so many people, why don't you try all the methods?"
"Do you know how much money it would cost and how many people would be needed to try them all?" Liu Jinghui laughed.
Qiu Li curled her lips: "I don't care about that, I just want the result."
Liu Jinghui was stunned for a moment, then said, "You little girl, your thoughts are exactly the same as your leader's."
