Chapter 1334

Liu Jinghui had been selling... reasoning outside for many years. What kind of guests hadn't he seen? Even if he felt Huang Qiangmin's request was a bit rude, he still faced it with a smile, just proposing higher conditions and prices.

Liu Jinghui: "To get certainty, first of all, expanding the scope is indispensable. Think about it, the crime scene is Ningtai County, one of the male victims is from Qinghe City, and the car was abandoned in Anwan City. There is reason to believe that the murderer is suspected of committing crimes across provinces. The possibility of committing crimes while on the run is very high. We have been searching for old cases for most of the day now. To be honest, the murderer's modus operandi can be considered significant. If the number of crimes is high, we should have found it if we could."

"Ningtai County is already checking the case files from 15 years ago. Qinghe City Bureau has also organized a team to check. To what extent do you think we need to expand?" Huang Qiangmin asked.

Liu Jinghui tested Huang Qiangmin with his gaze, feeling his tolerance level. His language was like a thin muscle needle, piercing into Huang Qiangmin's gluteal muscle bit by bit: "For a case 15 years ago, assuming the murderer has sufficient experience, regardless of whether he jumped and escalated or not, pushing forward for a year... preferably two years, I think it is still necessary."

Liu Jinghui: "Those who engage in taxi robbery cases, especially robbery and murder, generally only last for a year or two. In the early stage, they are not taken seriously, and they can earn some money. Later, they upgrade slightly, and their expenses and desires also come up. Then they do a bigger one, and the superiors start to take it seriously, start to establish a special task force to pursue the whereabouts of vehicles, mobile phones, and various properties, and start to inquire everywhere. Whether it is an individual or a gang, they should disappear."

Modern police rely on various technical means, rely on surveillance, mobile phones, and various laboratories. While 15 years ago or even 20 years ago, there were no surveillance cameras, no mobile phones everywhere, and no various micro-evidence. The only thing they could rely on was people.

Either the police are strong enough, or there must be eyewitnesses, or they can only rely on special information, which is actually inquiring in the underworld.

Similarly, the robbers back then didn't have point-to-point channels like Zhuanzhuan and Xianyu, and they obviously didn't have the ability to sell goods—if they did, why choose robbery, the work with the least technical content. Therefore, the robbers back then were also extremely dependent on various fencing channels.

So, when a case starts to hurt people or kill people, and when criminal police start to deeply understand various channels, the robber's fencing channels are basically blocked. What's left is basically being caught or running away.

Huang Qiangmin was an old criminal policeman who came from that era. He also had the experience of grabbing people in dance halls and asking questions back then. Listening to Liu Jinghui's words, although he felt the stinging pain, he still nodded and said: "It is also appropriate to put it forward for two years. However, 15 years ago or 17 years ago, in my impression, Ningtai didn't have such cases."

Liu Jinghui: "What about Qinghe City?"

Huang Qiangmin: "There shouldn't be either. However, I have to ask. Back then, there were no expressways to the city. I'm not sure if there were any in other counties."

Liu Jinghui saw that Huang Qiangmin used his "living fossil" experience to offset part of the offensive, so he added a little pressure and said: "What if it's personnel released from prison?"

Huang Qiangmin frowned slightly: "I have been in Ningtai County for 30 years. I don't have an impression in this regard, especially his rope-tying technique. If there were similar ones, I would definitely have an impression. Besides, if he was imprisoned 15 years ago, not to mention anything else, where were there taxis back then in Ningtai County."

"His rope-tying technique is a bit like the technique of a long-spear soldier." Liu Jinghui said.

Huang Qiangmin made an "um" sound and said: "It doesn't explain anything. So many people retire every year, and people around them can also learn."

Liu Jinghui tested that Huang Qiangmin was unwilling to stretch the timeline too long, but still tried to push it in one step and said: "Actually, even if we consider the problem of personnel released from prison, just looking at the case files and finding similar modus operandi, rope-tying techniques, etc., doesn't take much time. Just treat it as an ordinary stringing together of cases."

"Then if we consider criminals on the run, how to calculate it." Huang Qiangmin knew Liu Jinghui's goal, and at this time, he blocked him.

Liu Jinghui pushed, found he couldn't move, and simply scratched Huang Qiangmin's itch: "Then do we need to calculate it? Believe that the murderer only commits crimes in Ningtai, or only commits crimes in Ningtai County and Anwan City, and then disappears?"

"Hey... there's no way to do it like this." Huang Qiangmin sighed. In criminal cases, committing crimes while on the run is very difficult to handle.

Even if it's pursuit, it's pursued from one place to another. Or it's like economic cases, where different places have different victims and suspects. Although there are many places to run for investigation and evidence collection, it is ultimately targeted.

If criminal cases are only at the investigation level, you have to fly around the world. The difficulty of this investigation is too high. Mainly, many places run might not have results, purely running in vain. If you run to too many places, not to mention the funds, the leaders can't accept it first.

"It is indeed quite difficult. Or, let's wait and see what Jiang Yuan says when he comes back." Liu Jinghui still had expectations for the giant dragon.

Some city walls are tall, big, and thick, and I don't know how many earth and wood people built them day and night. If you use ordinary methods to attack, it must be a hard battle. But if there is a dragon, it's different.

The two looked at each other and reached a consensus. They both calmed down, did their own things, and waited with peace of mind for Jiang Yuan to bring back more resources.

Six hours later, Jiang Yuan, who had checked all the remains of the two deceased, returned to the conference room.

Huang Qiangmin and Liu Jinghui pushed away the teacups in front of them together and asked in unison: "How is it?"

"It depends on what you want. The identities of the two victims have been confirmed. The DNA report should also be out. If there is no phone call, there is no accident?" Jiang Yuan sat down a bit tired, took a teacup himself, and drank two sips of tea first.

"DNA has already confirmed the identity." Huang Qiangmin answered, then asked: "What is the result of your autopsy?"

"I wrote an autopsy report, but it didn't differ much from the results of the first autopsy, and the bones I saw didn't have much information." Jiang Yuan's answer made Huang Qiangmin panic.

"Then you just said..." Huang Qiangmin asked hurriedly.

Jiang Yuan looked at Liu Jinghui and said: "No more information is also part of the information, right?"

"Of course." Liu Jinghui answered very naturally.

At this time, Jiang Yuan winked at him.

In an instant, Liu Jinghui suddenly understood Jiang Yuan's meaning. This was clearly the dragon's breath pouring down from the sky.

"Ningtai County is not the starting point for this group of people?" Before this sentence of Liu Jinghui, there were at least three or four prerequisite inferences.

Jiang Yuan gave him firm support and affirmed: "Ningtai cannot cultivate such great thieves, and Qinghe City can't either."

Saying this, Jiang Yuan looked at Huang Qiangmin and said: "We have previously back-checked the cold cases in Ningtai County and Qinghe City. The murder cases have been back-checked to 30 years ago, and there is absolutely no murderer with the same modus operandi. Their modus operandi is clean and neat, and it is absolutely not the first time they have done this case."

"Is it possible that it is jump-style crime escalation?" Liu Jinghui quickly told Jiang Yuan the theory he had in front.

Jiang Yuan said categorically: "Impossible, the murderer must have killed people. They drove to the river beach just to kill people, and tying people was also to kill people easily, and burning the car was also to destroy the corpses. Moreover, the murderer's killing movements were clean and neat. If there was no experience of killing, and even no encounter with resistance, and no experience of the difficulty of digging a hole, how could they choose this method? They chose almost the most labor-saving means."

As everyone knows, digging a hole to bury people is very tiring and time-consuming, but ordinary people may not realize how intense the resistance will be when facing the threat of death. At the same time, they may not have seen how easily ordinary people will compromise when facing a powerful threat but not necessarily death.

A murderer who can easily and smoothly use the difference between threat and death threat is like a businessman who is good at using information gaps to make money. Not only does it require vision and means, but it must also require experience and practical operation to be applied skillfully.

Liu Jinghui knew the truth in this, but he lacked sufficient information. If there were no Jiang Yuan, he might have to flip through old papers for many days, just like he did before, and might not necessarily get the answer. If it weren't for this, he wouldn't rely on Jiang Yuan to handle cases every day.

Of course, Jiang Yuan couldn't easily draw a conclusion, but he was too familiar with Ningtai County and Qinghe City. Not to mention Ningtai County, he had cleared a round of cold cases early on. For slightly larger cases, especially those of the eight major serious cases, Jiang Yuan had long ago memorized them by heart. It was the same within the scope of Qinghe City. Not to mention the cases sent by various county bureaus, just in the "Cold Case Attack Year" initiated by the Qinghe City Bureau, Jiang Yuan had spent a lot of energy and time searching for various types of cases.

Not to mention anything else, for robbery and murder cases, no matter whether Jiang Yuan solved them or not, he had absolutely scanned the basic information once. It's not for nothing that criminal police must be localized. The more criminal police who are deeply cultivated locally, the more confident they are when facing such cold cases, old cases, and stringing together cases.

"If this is the case, we have to cast a big net." Liu Jinghui said, looking at Huang Qiangmin.

Jiang Yuan also looked down at Huang Qiangmin with a calm face.

"Do it!" Huang Qiangmin was too familiar with this script. He had just been vaccinated by Liu Jinghui for so long, and there was no more luck. He said himself: "Xu Taining, right?"

Since the big net is cast, what else can he say? Waiting, he could only wait for Jiang Yuan to say this word.

Jiang Yuan and Liu Jinghui nodded together, revealing an expression of "the child can be taught."

"What about the scope? Where should the big net be cast?" Huang Qiangmin asked sullenly. In recent years, he had saved up some family wealth, and he couldn't spend it all, right?

Jiang Yuan was understanding, took the map, drew a circle around the scope of Shannan Province, and then asked Liu Jinghui: "Would you like to add something?"

"I think we can lean a bit to the north. After all, they ran to Pingzhou. Then they must be familiar with this side. Otherwise, if they ran to the port in the southwest, the illegal sale of vehicles there would be just as serious." Saying this, Liu Jinghui drew half an ellipse on the circle Jiang Yuan drew.

Huang Qiangmin looked at this circle-in-circle that covered a small half of the map and couldn't help but say: "You guys sell me."

"We can start from the cities we are familiar with." Jiang Yuan had thought about this problem on the road and said: "We only have so many people. It's impossible to really scan such a large area. I think we can make a few phone calls first, ask the criminal police teams of the cities and counties we are familiar with to help collect some intelligence information. We just want to find clues. The net eyes don't have to be too small, as long as we can catch fish, it's a success."

Huang Qiangmin's expression became vivid all at once, thinking to himself, Jiang Yuan still knows how to love people.

His train of thought also opened up all at once, nodding repeatedly and saying: "This is fine. If it's just contacting the cities and counties we are familiar with, I think we don't have to be in a hurry to empty our family wealth. In this, many cities and counties' criminal police teams want to establish friendly relations with us. Some cities and counties promised... the promises haven't been fulfilled. This is good. If we ask them to cooperate, they will certainly be willing!"

Liu Jinghui said very considerately for Huang Qiangmin: "You can let Jiang Yuan make the call, it should be easier to talk."

"Good, good, good, it still has to be Director Liu. This reasoning is done particularly well." Huang Qiangmin immediately gave a thumbs up.

Jiang Yuan naturally wouldn't refuse. This case was already a case of Ningtai County. He immediately summoned Wang Chuanxing and said: "Make a list of the cities and counties where we have done cases. You sort them, write down the phone numbers of the comrades in charge locally, and I will make the calls."
