After seeing off Liu Wenkai and finishing Wu Junhao's cake, Jiang Yuan continued to watch the surveillance camera, as boringly as a repeater of his senior year in high school.
Everything in front of me seems familiar, and it seems that there are questions with clear answers, but when I need to continue to move forward, I often worry that I have not done enough before and the answers given are not accurate.
After watching, Jiang Yuan picked up the cup and drank the tea. The surveillance video in front of him continued to play, but Jiang Yuan's eyesight began to drift.
Liu Jinghui knew at a glance that the dragon had something on his mind. He took a pack of soft Chinese medicine, opened it, handed one to Jiang Yuan, took one in his mouth, lit it for the two of them, and just puffed away the clouds.
With.
A cigarette burned to the middle, Jiang Yuan pressed the whole cigarette into the ashtray, and said: "From Shipozi gas station to the gas stations in the northeast, there are no gas stations within a radius of 400 kilometers. Kuangshan
There are traces of it.”
"Is he more cautious?" Liu Jinghui asked.
"Maybe, it can't be ruled out, but it's unlikely."
When Liu Jinghui saw Jiang Yuan say such a few vague words in one breath, he immediately gave him more confidence and said: "According to your judgment, with so many cases solved, there is nothing special about Ren Kuangshan."
It’s just that the case we are doing is special and the preparations are extremely thorough.
However, with modern technology, those who can escape for a period of time are considered to have been screened out. Such criminals, to a certain extent, are also somewhat talented.
Jiang Yuan pondered for a moment and said: "There are monitors in front of the refueling guns at gas stations. This time I paid special attention to whether there were any people hiding outside the monitors to refuel. In fact, the refueling guns at Shipozi Gas Station have already been monitored.
This is a relatively high level of violation.”
"A particularly small private gas station?"
"I will check the surveillance of nearby access roads." Jiang Yuan has high authority and strong support. He can even call surveillance videos across departments.
Liu Jinghui raised another possibility to help Jiang Yuan judge, saying: "There are many private oil sales in various places. Ren Kuangshan drives a big car, so he should have similar channels. If he secretly contacted the private oil dealer, then
Buy private oil, or maybe he will also steal oil?"
Those who drive large cars are basically faced with the problem of fuel thieves, so many vehicles are specially equipped with anti-theft fuel tanks. Even so, they cannot stop fuel thieves from using various innovative and life-threatening cracking methods.
Ren Kuangshan has been driving a large car for so long. Regardless of whether he has experience in this area or not, he must have the corresponding knowledge. The most important thing is that he definitely has channels to understand this information, whether it is stolen or bought.
"What do you think?" Jiang Yuan asked Liu Jinghui.
"If I were him..." Liu Jinghui thought for a long time and said, "I should choose the gas station. Because private oil dealers are unstable and unreliable. When you go to the gas station to refuel, Ren Kuangshan can wear a motorcycle helmet.
You can wear a facial kini to protect yourself from the sun, but when dealing with a private oil dealer, will the other party allow him to do this?"
What Liu Jinghui said is more down-to-earth. Although the concept of privacy is not emphasized in China, it does not interfere with your dress. No one cares about wearing a mask, sunglasses or a facial kini. But this is not the case when trading on the black market.
, if someone asks you to get rid of it, you have to get rid of it. Similarly, since the black market businessmen are doing illegal business, they don't mind getting an extra wanted reward.
"From the current point of view, the clue to refueling is broken." Jiang Yuan shook his head helplessly.
Liu Jinghui was not anxious anymore. He sat across from Jiang Yuan and said, "Let's not talk about the clues being broken. What did you find here?"
"Nothing was found." Jiang Yuan spread his hands.
"There is no discovery, maybe it is a discovery." Liu Jinghui paused and said: "Although it is true or false, I think you have been looking for it for a day. If you haven't found it yet, can you say,
Ren Kuangshan is not working hard anymore?"
"No more gas at the gas station." Jiang Yuan corrected.
"Private oil dealers... Although I don't think it is appropriate to choose private oil dealers, but... it is easy to prove, just grab a group and ask." Liu Jinghui said and called Wang Chuanxing over, and called the headquarters and
Wang Sheng, leader of the Meiyang City Criminal Police Detachment.
For a city's criminal police detachment leader, selling illicit oil is a gray industry that is as small as possible. It may not pay enough attention to it on weekdays, but as long as it pays more attention to it, for illicit oil dealers,
Just a heavy slap.
After making the call, Liu Jinghui turned around and said, "I assume there is no news from the private oil dealers. If this is the case, we must consider that Ren Kuangshan did not continue to refuel."
Jiang Yuan thought hesitantly, then nodded.
"If he had not continued to refuel, he would have probably abandoned the car." Liu Jinghui made a decisive judgment, with a somewhat determined expression.
One big difference between police investigation of cases and reasoning games is that the police can continue to increase the number of known items through investigation.
Reasoning games are actually very similar to problem solving. They both obtain a series of known conditions, and then begin to deduce the results and seek answers.
But when police handle cases, in fact, this part of deriving results is often very rigid. For most criminal police officers, it is actually just a few mature routines that are applied over and over again. The difference is that in the process of police handling cases, they always
It is possible to continuously add known conditions.
From this point of view, police investigation and reasoning games are completely opposite.
On the contrary, it is an old case and looks like a reasoning game.
At the same time, this is one of the reasons that makes ordinary criminal cases seem low-level.
Jiang Yuan couldn't help but look at Liu Jinghui and said, "If it is determined that he abandoned the car, did he switch to public transportation?"
"Yes. You need to refuel when you drive yourself. If you want to replace the battery on a tram... renting a tram is better than riding a motorcycle to refuel." Liu Jinghui shook his head: "That is, you can follow the line of the gas station to check. Ren Kuangshan could not have imagined this.
Layer, don’t think of him too complicated.”
"I have also checked the battery swap station, but now many parking lots can charge..." Jiang Yuan paused, and then said: "It is impossible for him to enter the city. There are too many vehicle bayonet points in and out of the city. Riding a motorcycle
It's possible to escape, it's too difficult to drive."
"Then I think there are two directions. One is that he lived near the Shipozi gas station, and the other is that he changed to other means of transportation. But I tend to change the means of transportation because I have to live nearby.
Coming down and living in the city, he still has to face the problem of getting in and out of the city. It is not difficult, but he still has to take a lot of risks. Furthermore, the city he is most familiar with is Meiyang City, which is still too close to the crime scene.
"
Liu Jinghui's judgment is somewhat of a gamble.
However, in terms of time efficiency, comprehensive reasoning is not only difficult to exist, but also lacks practical significance.
Jiang Yuan immediately recognized Liu Jinghui's judgment and said: "Then there are two steps. The first step is to increase the investigation in Meiyang City. We are all here. Please ask the Meiyang City Criminal Police Detachment to do more."
The corners of Liu Jinghui's lips curled up: "You are the only one who can say this."
Jiang Yuan: "The second step is to find public transportation to the Northeast."
Liu Jinghui nodded: "That's a few, airport, high-speed rail station, train station, bus station, car rental agency, hitchhiking. He is a big truck driver, he may also find a truck, or directly take a ride with a big truck, the probability is smaller.
But we can’t help but be on guard.”
"It's very difficult for him to fly, and it's not easy to get to the high-speed rail station. Others..." Jiang Yuan thought for a while and said: "You still need to refuel when renting a car. The same is true for taking a ride with a big car. After passing the vehicle bayonet
They still need to be photographed every time, but it would be better to send more wanted flyers to these places and go through them all."
"Then we still have to trouble the Meiyang City Bureau." Liu Jinghui smiled.
Jiang Yuan coughed twice and took out his mobile phone: "I don't have to worry about anything anymore."
