Chapter 1333

Jiang Yuan had long ago finished reading the autopsy report and various scene photos. At this time, he summarized the language and said: "Both victims were sitting in the back seat, with their hands tied behind their backs. Due to the fact that the burning surface was concentrated on the upper half, the heads of both people were burned very severely, and the skin on the upper body was basically burned away. But in the first autopsy, it could still be easily seen that the fatal wounds on the upper bodies of both people were the heart, one knife each, very accurately."

Jiang Yuan: "I flipped through the photos of the ribs after the two deceased were deboned. Neither of their ribs had knife marks. This shows that the murderer inserted the knife very accurately from the gap between the two ribs. This is not just accurate, it may also be related to the technique and experience."

Several people at the scene nodded as they listened.

The technique of killing, when talked about, is the art of killing. There is no telling how much experience has been summarized over thousands of years. Just the matter of killing with one knife, those who don't know the trade and act recklessly can't find the accurate position, and those who know the trade but have no experience also have difficulties in on-site operation.

It's like killing a pig for the New Year in the countryside. Even if it's a very skilled pig butcher, they often use their hands to touch the part where the knife is to be inserted, so that it is easy to avoid bones and good meat, and can stab the pig to death with one knife. Because the pig is tied up and controlled, even if the butcher's hand is touching the position of the knife, it cannot resist.

Similarly, the bodies of the two victims were also tied up and controlled...

This shows that the murderer has at least experience, at least has done a profession like a butcher, and knows how to kill.

The so-called clean and neat knife requires many knives to be practiced. There is no need to use killing pigs in the countryside as an example. Just killing a chicken, although it is just grabbing the chicken and slitting its throat, by reason, as long as the knife is sharp and the position is found correctly, anyone can end a chicken with one knife. In reality, very few novices killing a chicken for the first time can do it.

And don't talk about little girls; there are plenty of big boys who can't do it. In school, there are biology experiment classes, and you can see a lot of students who can't kill frogs, can't twist white mice to death, can't kill small fish...

The civilized atmosphere of modern society has significantly reduced the barbaric atmosphere of modern society, and also made the characteristics of murderers scarce.

Jiang Yuan counted on his fingers and said: "Stabbing the heart with one knife, this is the killing method. Tying the victim's hands to control them, this is the modus operandi. The way of tying is also a feature. The murderer has the habit of wrapping and tying the deceased's little finger tightly. I think we can start from these three points first to see if we can find other cases to string together."

Liu Zhuangshi hesitated for a moment at this time, raised his hand and said: "Regarding stringing together cases, we also considered similar directions at the time, but didn't find similar murder cases."

"You didn't know it was a taxi robbery type of case at the time." Liu Jinghui said euphemistically: "You should have first considered determining the identity of the victim and the identity of the vehicle at the time, and then considered the stringing together of similar murder cases."

"It's about like that." Liu Zhuangshi was not embarrassed to admit it either. This was originally the conventional route.

"No similar murder cases doesn't mean there are no similar cases." Liu Jinghui smiled and said: "For taxi robbery type cases, the criminal himself has escalation. If you knew it was this type of case at the beginning, you should have considered that taxi robbery and murder is often the state of the criminal in the final stage. Before this, the criminal often commits robbery multiple times, but not necessarily murder."

These words of Liu Jinghui not only made Liu Zhuangshi's eyes light up, but also didn't annoy anyone at all, fully showing the high-level quality of a senior police officer from the Provincial Department.

Liu Zhuangshi nodded slowly: "When handling this case, I was still working at the City Bureau. I have already asked people to contact the police officers who handled it at the time. The comrades in charge at the time have already retired... If we consider it from the perspective of taxi robbery type cases, we can first pull a list of cases from that year to see if there are any discoveries."

Liu Jinghui nodded slowly, feeling that Liu Zhuangshi was worthy of being a leader of the Criminal Investigation Detachment. In a short paragraph, he both cleared himself of responsibility, explained the situation, and expressed his personal practical spirit, which was very leadership-capable.

Bureau Chief Wu Jingwei saw that the discussion had results, so he made a final decision: "Then let's move according to this plan first, and take out the cases before and after this case to look at..."

"I'll add one point." Liu Jinghui coughed and said: "The criminals of some similar cases in those years were not only doing carjacking cases, but also included fencing. Those big brothers with underworld backgrounds can all be found and asked. Since these people are very skilled in committing crimes, and we also guess they have corresponding experience, they are not people living in a vacuum. In the environment of those years, there are always people who know them."

Wu Jingwei nodded slowly: "On this point, it is indeed where we didn't do well enough. It should be that the case handling was not meticulous enough, and problems appeared... However, it has been 15 years. If the criminals were just robbing and fencing, they have already been released. On this point, that... Little Li, you organize a team from the bureau to contact the comrades of the Justice Bureau, and then communicate with the district bureaus and police stations below to see if we can find as many ex-convicts as possible to inquire."

If we follow the method Liu Jinghui said at the end, it shows that the Anwan City Bureau was not good enough in investigation and judgment in this murder case 15 years ago. At the very least, it shows that they didn't do it carefully enough, or were not smart enough.

However, it has been 15 years after all. If it is said that the public security and investigation capabilities of the two major super cities 15 years ago had some things to say, for places like Pingzhou Anwan, they basically relied on the old methods of old criminal police. It is common to rush in one direction in investigation, and not considering it comprehensively, just like they didn't take the criminal police academy exam back then, it wasn't that they really didn't want to.

Wu Jingwei still felt that he should admit his mistake in front of Jiang Yuan, but soon covered it up with work arrangements.

Jiang Yuan and others all followed Wu Jingwei's train of thought. Several people discussed the specific details for a while. Ten minutes later, orders began to be issued layer by layer.

At this moment, Huang Qiangmin's emotions were released all at once.

Among the people at the scene, he was the most familiar with Wei Zhengguo, and also the only police officer who had experienced the whole event. When the image of today's special task force overlapped with the special task force of 15 years ago, his psychological burden also became greater.

"Should we notify Team Leader Wei?" Jiang Yuan walked to Huang Qiangmin's side and asked in a low voice.

Huang Qiangmin was silent for a few seconds and said: "Don't be in a hurry."

"Then I'll go check the remains." Jiang Yuan prepared to do a good second autopsy. Although because of the age, only bones were left, there was still a chance to get some information.

Liu Zhuangshi quickly organized several conference rooms and asked people to move the massive amount of case files over.

Anwan City Bureau's electronicization was done very late. To find case information from 15 years ago or even earlier, information like fingerprints can naturally be checked on the intranet, but to find the modus operandi, or things like tying methods, especially to find the modus operandi in small cases back then, electronic files were not enough.

After all, with the number of cases back then, the degree of attention to simple taxi robbery cases might be about the same as the degree of attention to mobile phone theft cases in later generations.

Liu Zhuangshi invested in the process of flipping through old case files with great enthusiasm.

At the same time, the criminal police of Ningtai County Bureau were also mobilized. Under the command of Criminal Investigation Brigade Captain Liu Wenkai, they began the arduous and extraordinary work of backtracking old cases. Shannan's electronicization conditions were limited compared to Pingzhou. In the end, everyone had to flip through files.

The members of Jiang Yuan's cold case special task force were also filled in, flipping through files together.

To show their attention, the leaders simply stayed at the Criminal Investigation Detachment, drinking tea while boosting morale.

According to their understanding of Jiang Yuan, as long as the special task force is opened, and as long as Jiang Yuan enters the state of handling the case, the next step is celebration time.

Time passed minute by minute, and the taste of the tea became lighter and lighter.

Huang Qiangmin felt the familiar atmosphere, first asked someone to change a pot of tea, and then said: "It's not certain that we can get results today. I think we shouldn't all guard here, let's go back and do other things first..."

"That's fine." Bureau Chief Wu stood up and said: "If there is any situation, notify me at any time. I am also on standby at any time."

"Certainly." Huang Qiangmin shook hands with Bureau Chief Wu and others in turn.

Until everyone was sent away, Huang Qiangmin turned his head, found Liu Jinghui again, and said: "So many people are investigating, and there is no feedback at all. Where do you think the problem lies?"

Liu Jinghui had been thinking. At this time, he said: "There are many possible situations. What I am more worried about... is the jump-style escalation of the murderer."

"From what degree, jumping to murder?"

"From robbery without injury, directly to robbery and murder." Liu Jinghui gave a very direct answer, then looked at Huang Qiangmin and said: "You have experienced that time. When there were many taxi robbery situations back then, some taxi drivers were robbed but didn't report it to the police, because recording statements and such took time and delayed making money. Anyway, they were robbed..."

"And they couldn't catch anyone, and even if they caught them, they couldn't see the money." Huang Qiangmin added.

Liu Jinghui nodded: "Assume a situation. The murderer committed robbery without injury once or multiple times, and the victim didn't report it to the police. In the process of a certain robbery, the victim Li Huimin appeared accidentally. She was a police family member, and her words might have stimulated the murderer, which led to the escalation of the crime..."

"Ningtai's taxis have always been able to share rides. Li Huimin did have the possibility of accidentally taking a ride. However, you and Jiang Yuan both judged that the murderer's killing method was skilled and the modus operandi was skilled. If he was a jump-style escalation, how was it practiced?"

"If we want to talk about possibility, the murderer could have done other types of cases, such as kidnapping, robbery, or murder, and found that robbing taxis is simpler, so he decided to do this. Another one..." Liu Jinghui paused and said: "The taxi robbery trade, the people who liked to do such cases the most in the past were ex-convicts who had just been released from prison. If the murderer had done similar cases a long time ago, and was released from prison later, and committed the crime again..."

Taxi robbery doesn't need capital, doesn't need technology, and doesn't even need to scout locations. Many ex-convicts enter society suddenly, with blank eyes. If they decide to commit a crime to get money, many people will subconsciously choose this mode.

From a logical perspective, Huang Qiangmin admitted that what Liu Jinghui said made sense. But if he were to correct the investigation scope according to his reasoning, it would be equivalent to expanding the type of case and lengthening the time span...

"I don't want to hear possibility, I want to hear certainty!" Huang Qiangmin pulled Liu Jinghui back to reality in one mouthful.
