"How many explosive eucalyptus accumulations are there in Qinghe City?"
Jiang Yuan looked at the file photos on the desktop and suddenly asked something.
Perhaps because the provincial department sent personnel to supervise the investigation, there are many photos left behind by the explosion at Qu'an Station, and the files are neat and detailed. However, they can provide few clues to solve the problem.
Jiang Yuan read it from beginning to end, but couldn't filter out any useful information. The first thing that came to his mind was to use the exchange opportunity obtained by the second-class skill to get an explosive skill.
Since it is an exchange, it is natural to hope that the skills exchanged can be used in a wider range of applications, so Jiang Yuan asked this question.
The conference room was filled with police officers from Jiang Yuan's special team. Everyone was performing their duties and looking for clues.
Wang Chuanxing and Tang Jia were working part-time as Jiang Yuan's assistants, so they started investigating after hearing this.
"No more. Just this eucalyptus." Huang Qiangmin was sitting at the other end of the conference table, just under the sun. He was drowsy when he heard Jiang Yuan's question and answered it without thinking.
Jiang Yuan was a little surprised: "Just one?"
"Do you think it was a serial explosion?" Huang Qiangmin suddenly became alert. Jiang Yuan had discovered serial murders like this before.
Jiang Yuan shook his head: "That's not true, I'm thinking about something else."
A skill is exchanged for a tool. If it is like the last kidnapping, and the situation is forced, it will be changed. There is no need to hesitate too much. After all, there are more skills than the burden. But for now, the murderer should die earlier.
Dying later is not within the scope of Jiang Yuan's consideration at all, and using skills such as explosion trace detection may not be able to solve this problem.
If it is found, there may be a greater chance. It is an old accumulation from 8 years ago. Whether it is redeemed for a LV4 major skill or a LV5 minor skill, the help it can provide is limited.
In comparison…
"Call Liu Chu." Jiang Yuan's voice was not loud, but Huang Qiangmin was shocked when he heard it.
"Are you going to call me Liu Jinghui?" Huang Qiangmin was more surprised: "Don't you usually just look at the photos and figure it out?"
"Huang Bureau, how can it be so easy to break the case?" Jiang Yuan looked at Huang Qiangmin strangely, and the policeman on the special shift also looked over with some confusion.
Huang Qiangmin avoided Jiang Yuan's eyes in embarrassment, and couldn't help but reflect on himself: Could it be that I have been bragging about Jiang Yuan too much recently, and I believed it first?
Speaking of which, if you want to sell people from the public sector to the public for a fair price, you must have some words. Huang Qiangmin has experienced it many times over the past few days. The best selling point is the 100% break-in rate, which is more than 100%.
The fast breaking speed, and the ultra-low breaking cost - Jiang Yuan boasted about it so much that Huang Qiangmin himself believed it.
Thinking of this, Huang Qiangmin's expression became more solemn. As a criminal police officer, it is not good to lose objectivity. He said: "I just think that you are more powerful than the experts from the provincial department combined. With Liu Jinghui... I really have to give him a
Opportunities are not impossible.”
"It's better to invite Liu Chu to come. There are few clues in Guzi and there is a lot of evidence. Liu Chu will take a look and maybe he can pull out a few clues."
Too much useless information and too little useful information are the characteristics of this incident and the characteristics of most explosions.
Liu Jinghui is obviously very suitable for this kind of application scenario. In contrast, it is quite time-consuming for Jiang Yuan to scan through the evidence one by one.
Seeing this, Huang Qiangmin nodded: "Okay, it's a case that the provincial department has been involved in, so it's appropriate for them to come forward personally."
After he finished speaking, he went out to communicate.
Jiang Yuan continued to look down at the photos, pondering each one.
Similar to previous accumulations, the key problem with this type of accumulation is that most of the clues have been tracked and investigated during the discovery period. If they were not discovered back then, how can they be investigated now?
On the other hand, there was actually a lot of information involved in the case, and most of it was useless. Eight years ago, hundreds of criminal police officers were used here to conduct various investigations, and the investigation was carried out three times.
This failed to break the eucalyptus. From this, we can also speculate that the big eucalyptus was wasted but not broken, which had an impact on the people who handled the eucalyptus. At least, Jiang Yuan had never heard of the name Qiu Yue.
Liu Jinghui arrived early the next morning.
He came by car wearing a police uniform and had a famous driver by his side. Similar to Jiang Yuan, since he encountered danger, he rarely walked alone.
When he arrived at the place, he didn't waste any time. During the bus ride, he read a lot of files. When he arrived at Qu'an Branch, he looked at the photos for a while and said, "It's just like what I thought. This eucalyptus is an explosive."
The remnants are the biggest piece of evidence and the most difficult to find information about."
"Are we going to search the source of the remnants? The special team conducted a very detailed investigation back then, and I didn't see any obvious flaws." Jiang Yuan looked at the pictures and read the files. To this day, he still thinks
It is almost impossible to directly trace the source of the residue of explosives. The most important thing is whether we checked it back then. If we don’t have new ideas now, we will go through the same old path again, but we hope to reach a different ending.
, that is unrealistic.
Liu Jinghui shook his head: "I have no idea now. However, the remnants of this explosive are actually quite interesting."
"Oh, how do you say it?"
"For most explosions, the detonators are usually detonators or fuses. There are many industrial and mining enterprises in our province. These two things...Normally speaking, if these things cannot be easily obtained, there will be no explosions.
Yes." Liu Jinghui has his own logic.
Jiang Yuan nodded slightly.
Liu Jinghui said: "But from another perspective, this eucalyptus is quite powerful. The explosive uses black powder and the battery detonates. It can be said that they are all relatively easy to buy, but the power is not bad. After a long time,
It has been eight years, and it is rare to see an explosion of this level."
"Similarly, after eight years, the murderer has not made any similar explosions again. This fact deserves further investigation."
"The murderer's original purpose was not achieved. The victim detonated the explosive in advance. If so, why was the bomb not resettled? Or was the explosion carried out elsewhere, or the murderer's purpose changed? Or? The murderer?
What unexpected situation happened?"
Jiang Yuan was stunned for a moment. He was not familiar with explosives. As for the types of explosives, he was not very clear about it. But what Liu Jinghui said made sense. The murderer had not been caught. The explosion was regarded as a terrorist attack.
Why didn't the murderer continue to commit crimes?
This was originally what the special team was most worried about, and the provincial department immediately intervened in order to avoid this situation.
In fact, since the murderer is not directly involved in the explosions, the probability of them happening continuously is very high. For example, there was a man named Hu who had three explosions in a row just because his girlfriend broke up with him and took away 20,000 yuan. He had nowhere to ask for it.
Exploding eucalyptus to gain attention...
What was the purpose of the murderer who exploded at Qu'an Station in creating such a big bomb? Did he achieve his purpose?
"Time is our biggest disadvantage compared to the professional team, and it is also our biggest advantage." Liu Jinghui has a slicked back hair, clean collars on his shirts, a standard image and good temperament, and a very confident expression.
"If no one has an idea, I suggest that we start from the outside and do some investigation work first." Liu Jinghui said that he had no idea, but in fact he did have an idea. However, his idea was a bit scratchy.
After all, if you want to blindly guess the murderer's intention, it is sometimes really difficult to guess something like this. Let's still use the example of Mr. Hu, the main messenger of the three explosions. His real purpose may be that he has no guts and no courage.
Shun, he wanted to vent, or he just wanted to ask for an explanation from his ex-girlfriend, but this was all his own inner drama. The truth that the police could trace was: he took away 20,000 yuan because of his ex-girlfriend, and
Three explosions were made.
Who can guess this answer?
Several people looked at each other and felt that it was quite difficult.
Huang Qiangmin couldn't help but sigh and said: "The mouse hangs a bell on the cat."
This is his evaluation of Liu Jinghui’s reasoning. The reasoning is good, but what about the execution?
Liu Jinghui chuckled and didn't care about Huang Qiangmin's evaluation. What kind of reasoning do these Muggles know? Reasoning also requires information. It is reasoning step by step, advancing step by step, obtaining information step by step, and then reasoning again, forming a positive feedback loop.
, and finally get the correct result.
Even if it is really to let the mouse hang a bell on the cat, it is not an impossible task. There is always a way. To break down this task, it can be a preset trap, a multi-mouse attack, or night operations, etc...
Of course, if some mice are particularly good, they just put bells on cats...
Liu Jinghui looked at Jiang Yuan expectantly and said, "I'm going to do some reasoning and you can see where is a suitable breakthrough point?"
"It's best to have something tangible," Jiang Yuandao said.
Liu Jinghui smiled, thought for a while, and said: "Let me talk about a few possibilities first. The first one is about the murderer. The murderer suddenly stops committing crimes. The most common situations are that one is that freedom is restricted, the other is that the environment is restricted, and the other is that life and
The mood changed."
"If it's the first point, we can check the list of people who were arrested and detained eight years ago. Secondly, we can check the list of people who died and were seriously injured, including people who were seriously ill and people who had traffic accidents during this period, especially
Those who died accidentally, especially those from industrial and mining enterprises and those with corresponding backgrounds and abilities..."
"Second, environmental issues. The murderer may have gone abroad and left the local area. It is also possible that he was discovered by people around him - this cannot be confirmed, but I think that if this is the case, more measures should be taken.
Look for more passive factors. For example, enrolling in a higher education, studying abroad, being sent on a business trip to other places, or taking the public examination and teaching, and applying for a position in a company in another place."
"Third, in terms of life, have you fallen in love during this period? Have you gotten married? Have you given birth to a child? Or divorced, broken up, your child or family member is sick, you have a sudden illness... Also, you have received a promotion or a salary increase.
, won the lottery, made a sudden fortune..."
Huang Qiangmin and others looked good at first, as if they were criminals who were sentenced for other crimes but escaped screening or investigation. It happened from time to time. I don’t know how many police reports I have seen. This is also the case.
It's relatively easy to check, the time and name are very certain, it's just a matter of taking the time to sift through it.
But from the ears of Huang Qiangmin and others, Liu Jinghui had a tendency to go too far. If everything like studying abroad had to be checked, even if Qu'an was a small place, it would be a huge workload.
In the end, promotions and salary increases count. How much does the salary increase count? Does fifty yuan count?
The scope was so expanded that Huang Qiangmin felt as if Liu Jinghui wanted to touch everyone in Qu'an County.
If this is the case, it would be better to go to Xu Taining than to Liu Jinghui.
Liu Jinghui also felt that there were too many bells tied around the cat's neck. He touched his own neck and pondered: "Then let's check from two directions first. One is the list of criminals. The time can be extended a little longer to find out what the murderer is.
All crimes committed within 2 years are counted. On the other hand, let’s compare the explosions in other places, including similar ones, attempted ones, and unfinished ones.”
Huang Qiangmin nodded slowly after hearing this.
The criminal police captain of Qu'an County also agreed: "Liu Chu is still very capable."
These two points were both parts that the special team at that time was unable to investigate.
Although the provincial department dispatched personnel in a hurry, after three or four months of investigation, the large-scale investigation almost came to a standstill. On the one hand, all the clues had been investigated but to no avail; on the other hand, the risk of serial explosions was decreasing.
Already.
However, reduction does not mean that there is no such thing. Some murderers who commit explosives have a different concept of time than those who commit ordinary crimes. They may spend several months, or even one or two years, improving the explosives and modifying them.
and improve your plans.
Therefore, anyone who accidentally lost the ability to operate during this period of time is considered suspicious and has not been investigated by the special team.
The explosions or attempted explosions in other provinces may also have been carried out by the same murderer, which can also explain why he did not continue to commit crimes.
Compared with other random speculations, the two directions proposed by Liu Jinghui are within a limited and controllable scope, and the cost of investigation will not be too high. They are exactly the type that the criminal police captains like.
