Chapter 1161

After sending Liu Wenkai off and finishing Wu Junhao's bread, Jiang Yuan continued to watch the surveillance, as dull as a fourth-year high school repeater.

Everything in front of him was familiar, like a problem with a clear answer, but when it was necessary to continue pushing forward, one often worried that what was done before wasn't enough and that the answer given wasn't accurate.

Watching and watching, Jiang Yuan picked up his cup and drank tea. The surveillance video in front of him continued to play, but Jiang Yuan's gaze had already drifted.

As soon as Liu Jinghui saw this, he knew the dragon had an idea. He took a pack of Soft Zhonghua cigarettes, opened it, handed one to Jiang Yuan, lit one for himself, and then lit one for the two of them, just puffing away like that.

When the cigarette burned to the middle, Jiang Yuan pressed the whole cigarette into the ashtray and said, "There are no traces of Ren Kuangshan at the gas stations within a 400-kilometer radius from the Shipozi Gas Station toward the Northeast."

"He's become more cautious?" Liu Jinghui asked.

"Perhaps, it cannot be ruled out, but the possibility is not high."

Seeing Jiang Yuan say so many vague words in one breath, Liu Jinghui immediately boosted his confidence: "Speak according to your judgment. After solving so many cases, Ren Kuangshan is nothing special."

It's just that the cases he committed were special and his preparations were particularly thorough.

However, under modern technology, those who can escape for a period of time are considered to have been screened out. In a sense, such criminals also have a bit of talent.

Jiang Yuan pondered for a moment and said, "There is surveillance in front of the fuel nozzles at gas stations. This time, I paid special attention to whether there was any situation of hiding outside the surveillance to refuel. In reality, the fuel nozzle at Shipozi Gas Station was already at a relatively high level of violation."

"A particularly small private gas station?"

"I will check the surveillance of the roads entering and exiting the vicinity." Jiang Yuan's authority was very high, and the support he received was strong. Even if it was cross-departmental retrieval of surveillance video, he could do it.

Liu Jinghui proposed another possibility to help Jiang Yuan judge: "There are also many cases of selling private oil in various places. Ren Kuangshan is a heavy-truck driver; he should have similar channels. If he secretly contacted a private oil seller and bought private oil, or perhaps, could he also steal oil?"

Heavy-truck drivers basically have to face the problem of oil thieves, so many vehicles are specially equipped with anti-theft fuel tanks. Even so, they can't withstand oil thieves using various innovative and death-defying cracking methods.

Ren Kuangshan has been driving heavy trucks for so long. Regardless of whether he has experience in this area, he must have the corresponding knowledge. Most importantly, he definitely has channels to understand information in this area, whether it's stealing or buying.

"What do you think?" Jiang Yuan asked Liu Jinghui back.

"If I were him..." Liu Jinghui pondered for a long time and said, "I should choose a gas station. Because private oil sellers are unstable and unreliable. Going to a gas station to refuel, Ren Kuangshan can wear a motorcycle helmet or a facekini for sun protection, but when trading with a private oil seller, does the other party allow him to do that?"

Liu Jinghui's words were more grounded. Although the concept of privacy is not emphasized much in China, it doesn't interfere much with your dress and appearance. Wearing masks, sunglasses, or facekinis, no one cares. But it doesn't work in black market transactions. If someone asks you to take it off, you have to take it off. Similarly, black market merchants, since they are doing illegal business, don't mind taking an extra bounty for a wanted person.

"As of now, this lead on refueling is broken." Jiang Yuan shook his head helplessly.

Liu Jinghui, on the contrary, was not in a hurry. He sat opposite Jiang Yuan and said, "Let's not talk about the broken lead first. Tell me, what have you discovered here?"

"No discovery." Jiang Yuan spread his hands.

"No discovery might also be a kind of discovery." Liu Jinghui paused and said, "Although it is said that one should prove existence rather than non-existence, I see you've been looking for a day. If you haven't found anything, can it be said that Ren Kuangshan hasn't refueled again?"

"Hasn't refueled at a gas station." Jiang Yuan corrected.

"Private oil sellers... although I think choosing private oil sellers is inappropriate, however... it's simple to prove. Just catch a batch and ask." Liu Jinghui said, calling Wang Chuanxing over and calling the command center and Wang Sheng, the detachment commander of the Meiyang Criminal Investigation Detachment.

For a criminal investigation detachment commander of a city, those selling private oil belong to a gray industry that couldn't be smaller. They might not get enough attention on weekdays, but as long as the level of importance is raised, it will be a heavy slap to the private oil sellers.

After Liu Jinghui finished the call, he turned back and said, "I assume there is no news from the private oil sellers. If so, we have to consider that Ren Kuangshan hasn't continued to refuel."

Jiang Yuan thought about it hesitantly and then nodded.

"If he hasn't continued to refuel, he likely abandoned the car." Liu Jinghui gave his judgment decisively, his expression even a bit certain.

A major difference between police investigating cases and reasoning games is that the police can constantly increase known items through investigation.

Reasoning games are actually very similar to doing problems; they are all about obtaining a series of known conditions and then starting to deduce the results and seek answers.

But when the police handle cases, the part of deducing the results is often actually very rigid. For most criminal police officers, it is actually just a few mature routines that are constantly and repeatedly applied. The difference is that in the process of police handling cases, they can always constantly increase the known conditions.

From this point of view, police investigating cases and reasoning games are completely opposite.

On the contrary, cold cases resemble reasoning games.

At the same time, this is also one of the reasons why ordinary criminal cases seem less high-end.

Jiang Yuan couldn't help but look at Liu Jinghui and said, "If it is determined that the car was abandoned, did he switch to public transportation?"

"Should be. Driving yourself also requires refueling. If it's an electric car, switching batteries... renting an electric car is not as good as riding a motorcycle and refueling." Liu Jinghui shook his head: "It's just that you can follow this lead of gas stations to investigate. Ren Kuangshan can't think of this level; we can't think of him too complexly."

"I've also checked the battery swapping stations, but now many parking lots can charge..." Jiang Yuan paused and then said: "He can't enter the city. There are too many vehicle checkpoints entering and exiting the city. It's possible to dodge them on a motorcycle, but it's too difficult to drive."

"Then I think there are two directions. One is that he settled down around the Shipozi Gas Station, and the other is that he switched to other means of transportation. But I lean toward switching means of transportation, because to settle down nearby and live in the city, he still has to face the problem of entering and exiting the city. It's not difficult, but he still has to take quite a risk. Furthermore, he is most familiar with Meiyang City, and this place is still too close to the crime scene."

This judgment of Liu Jinghui's carries a bit of a gamble.

But in terms of time efficiency, comprehensive reasoning is not only difficult to exist but also lacks practical significance.

Jiang Yuan recognized Liu Jinghui's judgment for the first time and said, "Then two steps. The first step is to increase the investigation in Meiyang City. Since we're here, please ask the Meiyang Criminal Investigation Detachment to put in some more effort."

Liu Jinghui's mouth curled up: "Only you can say this."

Jiang Yuan: "The second step, we look for public transportation to the Northeast."

Liu Jinghui nodded: "That's a few types: airports, high-speed rail stations, train stations, bus stations, car rental agencies, and ride-sharing. He is a heavy-truck driver, so he might also look for trucks or take a ride-sharing truck directly. The probability is smaller, but we can't guard against it."

"The difficulty for him to take a plane is very high, and the high-speed rail station is not easy either. Others..." Jiang Yuan thought for a moment and said, "Renting a car still requires refueling, and taking a ride-sharing truck is actually the same. When passing through vehicle checkpoints, they will be photographed all the same. However, sending more wanted posters to these places and going through them all is also good."

"Then we still have to trouble the Meiyang Municipal Bureau." Liu Jinghui smiled.

Jiang Yuan coughed twice and took out his phone: "It can be considered as not bothering two masters for one thing."
