Solve the case: Justice makes you stronger

Four cases to be investigated together?

Everyone present was stunned for a moment and didn't come back to their senses for a while.

Xu Luo, is this going to investigate four cases in one go?

Even if he is very powerful, the cases he has handled so far have all been resolved within three days, but this is inevitably a bit of a nobody, right?

"Xu Luo, what do you mean by this?" Liang Bin frowned, his eyes hinting madly.

He thought that after reading the case file, Xu Luo thought that the four murders were too simple, so he wanted to solve them in one go.

Although there is nothing wrong with this, it is not good to say it in front of so many mirror inspectors.

Xu Luo looked at everyone's expressions in his eyes and understood that they had misunderstood, so he explained: "I don't want to investigate four cases at the same time in one go, but these four cases are actually just one case!" "

Even if he can really investigate four cases at the same time and have the confidence to solve the case, Xu Luo will not do it, it is a fool's behavior.

"That's good!" Liang Bin breathed a sigh of relief.

It's not that I plan to investigate four cases in one go, no matter whether Xu Luo can do it or not, it seems too much to say it, which is not conducive to unity.

If it's a case, it's fine... What a.

"You're saying that these four cases are actually one case?"

Liang Bin, who reacted, widened his eyes and asked in surprise: "Another serial murder case?" "

"Yes." Xu Luo nodded affirmatively.

"How is that possible?!" Liang Bin took the three case files and looked at them again, trying to find some clues from them.

He had seen these four case files, or the mirror inspectors who were present knew the information, and they did not find that these four cases were connected in the slightest.

The first murder occurred on June 15th, that is, half a month ago, the deceased was a club head lady named Shi Qianqian, and it is said that if you want to have a wonderful night with her, it starts with 10,000 yuan.

The deceased was found dead in his bed the next day by a part-time cleaning worker, reportedly with a strange smile on his face.

Later, after the autopsy of the forensic doctor Qin Zhi, it was learned that Shi Qianqian's time of death was ten o'clock in the evening on June 15, and the cause of death was that someone had been injected with excessive potassium cyanide.

The lethal dose of potassium cyanide is between 50-250 mg, which is about the same as the lethal dose of arsenic, and the decision of lethality depends on the blood concentration, which is about 0.5 μg/ml for cyanide poisoning and ≥ 1 μg/ml for lethality.

Shi Qianqian was found to have a potassium cyanide concentration higher than 2μg/ml, which was obviously murdered.

And after Shi Qianqian was killed, she was brutally removed from her uterus by the murderer!

The second case occurred on June 19, and the deceased was a big stomach anchor named Lang Hongyu, who was well-known in Fucheng, and the cause of death was arsenic poisoning.

It's interesting to talk about this case.

That day, Lang Hongyu opened a live broadcast to eat buffet, and there happened to be mulberry wine and lobster in front of him, and at that time, someone who understood sent a barrage saying that these two foods together will produce As2O3, that is, arsenic, which will cause food poisoning.

As a result, Lang Hongyu directly called the brothers to reward a wave, and he immediately dried lobster and mulberry wine.

So Lang Hongyu started eating.

After that, he got food poisoning in front of everyone, was taken to the hospital, and finally died.

At first, everyone thought it was an accident, and the family claimed the store.

The shopkeeper refused to request an autopsy, and the autopsy revealed that the real cause of death was arsenic poisoning, but the amount of arsenic was completely more than the amount produced by mulberry wine and lobster.

It can be concluded that this case was deliberately poisoned.

So it became a homicide.

The third case, which occurred on the night of June 23, was found dead in the casino office by Xu Xin, the owner of a private casino and a loan shark, and the cause of death was cardiac arrest and myocardial infarction.

But the man did not have a heart condition, and there was no family history of heart disease in the family.

Finally, after investigation, it was found that someone had been injected with sodium cyanide.

The police believe it is revenge from the enemy.

The fourth case, which occurred on the night of June 27, was a young homeless man named Qian Jinhao, whose cause of death was that his limbs were cut off and he died of excessive bleeding.

After a forensic autopsy, it was found that there were a large number of sleeping pills in the deceased's body, and the consciousness was that he was first stunned and then hacked to death.

After reading the four case files again, Liang Bin asked distressedly: "Xu Luo, how can these four cases be done by the same person?" "

Serial homicide, then of course the murderer is the same!

Generally speaking, the offender in this kind of case is easy to investigate and difficult to detect.

It is difficult to investigate because the murderers of this type of murder are generally high-IQ criminals, otherwise it is impossible to commit crimes continuously without being caught.

It's easy to check because criminals kill a lot of people, and it's easy to show flaws, and this kind of murderer has only two purposes for killing, which is nothing more than perverted murder and hatred killing!

Perverted killings are all because of some of their own problems, so they have to create continuous killings.

And hatred kills because some people have done something to the criminal together, and he wants to take revenge.

But either way, they can find common ground in the deceased to determine that it was a serial homicide.

And now, Liang Bin has read it carefully, and he has not been able to find anything in the case file that can prove that this is a serial murder case.

"We have investigated the social background of the four deceased very clearly!"

"Shi Qianqian, the clubhouse lady, Lang Hongyu, the anchor of the big stomach, Xu Xin, the owner of the underground casino, and Qian Jinhao, the homeless man, these four people are of different ages and social circles, and it is almost impossible to intersect with each other."

"Especially this homeless man, he came to Fucheng from other places and has no relatives."

"In other words, if they provoke the same person because of something, there is almost no chance of attracting revenge from the enemy."

"If it's a perverted murder, it's unreasonable!"

"The same modus operandi? The first and third cases were both injected with cyanide, which can be counted, and the second case of food poisoning can barely be involved, but the cause of death of the homeless man was excessive blood loss, which does not seem to be logical! "

"Time to kill? Well, these four murders were all three days apart, which is a point, but I'm more inclined to believe that it's a coincidence! "

After talking about his analysis, Liang Bin scratched his head with some distress.

If you just look at the case file, he can't find any common ground.

But he didn't think that Xu Luo would be targeted for no reason, which made people very distressed.

In fact, it was not only him, but everyone else at the scene frowned, trying to find a point that could be connected from these four case files.

Especially Jiang Ye, the leader of the second group, and Jiang Chen, the leader of the third group, they are considered Xu Luo's predecessors, and they have even participated in the investigation of four cases, and now they are in the state of concurrent investigation, so they are very concerned.

Combined investigation means that when there is not enough manpower due to mirror investigation, or when there are many cases, the case handling team mainly deals with one case and investigates one more case at the same time.

"Team Leader Xu, you can be betrayed, say it quickly, say it quickly!" Liang Tian was obviously not a patient person, and after thinking for a while, he began to pester Xu Luo without eyebrows.

Xu Luo didn't intend to sell Guan Zi, and explained directly: "It proves that these four cases are the same person in common, and it is not based on the age, occupation, or identity indicated." "

"It's the attributes of what they do!"

"Attributes?" The crowd was even more puzzled.

This is the first time they have heard this term brought to a case after so many years of being mirror investigators.

"That's right, attributes!" Xu Luo nodded.

He walked to a desk in a few steps, took a blank piece of paper and wrote, while asking, "Do you know the seven deadly sins?" "

The Seven Deadly Sins?

Many people are at a loss, the term sounds like it comes from a certain religion.

The mirror examiners are all scientific, and they don't know much about the seven deadly sins.

However, Liang Tian usually likes to gossip and read novels on the Internet, so he knew a little bit and immediately responded: "I know, it is called the classification of human evil deeds in a certain religious doctrine." "

"I think it was arrogant, jealous, angry or something..."

"That's right, that's it!" Xu Luo looked at Liang Tian with appreciative eyes, and then lifted the white paper and turned around, so that everyone could see it!

"The Seven Deadly Sins, or the Seven Deadly Sins or the Seven Original Sins, is a classification of human evil deeds in the doctrine of a certain Catholic Church."

"Those who fall into this category can directly form other unethical behaviors or Xi."

"The sins, in descending order of severity, are arrogance, envy, anger, laziness, greed, gluttony, and lust."

Lazy?

Greedy?

Gluttony?

Lust?

"Hiss~~"

At first listen, everyone found that there was nothing in it, but after thinking about it seriously, everyone realized what Xu Luo meant.

Liang Bin even picked up the case file and muttered: "From heavy to light, it is arrogance, jealousy, anger, laziness, greed, gluttony and lust, and vice versa..."

"Lust, Shi Qianqian is secretly photographed in the club, picking up customers at a high price, that aspect can definitely be regarded as indulgence!"

"Gluttony, Lang Hongyu is the anchor of the big stomach king, which corresponds to this overeating, that is, gluttony!"

"Greedy, Xu Xin has a black casino under him, and he lends money to usury, all of them are profiteering without production, and he has even forced a few people to death, absolute greed!"

"Lazy, I finally understand why there are a lot of homeless people in Fucheng, some of them have been here for a long time, why Qian Jinhao, a newcomer, will be killed, just because he is young, so he corresponds to laziness!"

Liang Bin is finally not stupid to get home, and it should be said that the mirror inspectors present are not stupid.

They didn't expect it at first, because they didn't have any knowledge reserves in this area, and they didn't have doubts about this aspect.

But after Xu Luo, a person whose strength is convincing, said that it might be a serial murder case, and gave a hint of the so-called attributes, they also figured it out at once, and they were not stupid enough to need a lot of explanations little by little.

"Xu Luo, are you human?" Liang Bin looked at Xu Luo like a monster, and his heart was very shocked.

In fact, it is not only him, but everyone else is the same.

Xu Luo's performance is too eye-catching, even if he knows the seven deadly sins, and even has an in-depth understanding, there is no reason to think about this aspect when he sees the four cases, right?

Moreover, Xu Luo read the four case files in front of them, and before reading them, he was told by Liang Bin to choose one of the four to solve, at this time he should fall into a blind spot in his thinking, and he inherently thought that the four cases were okay, and it was right to choose one to solve.

But he was stunned to find that this might be a serial murder case, which can no longer be described with quick thinking, right?

"Luck, it's all!" Xu Luo shrugged.

He's not being modest, he's telling a fact.

The Great Xia Dynasty's management of the Jingcha envoy was much more lenient than that of being a public servant of the people in his previous life, and he could even develop a side hustle to improve his life, as long as there was no direct affiliation between this sideline and the Jingcha envoy's profession.

For example, speculating in individual stocks, writing a novel, and so on.

As early as when Xu Luo was in college, he became a glorious online novelist (Wen Copyist), focusing on suspense novels, and now the best-selling suspense novels in Xia Guo "Chasing the Murderer in the White Night" and "Ten Deadly Sins" are his masterpieces.

This time, he was able to see the case file and found the problem, mainly because he was planning to write a new suspense novel during this time.

Well, it's going to copy a novel "Seven Deadly Sins" that was very popular in his previous life.

He's just been sorting out the outline lately, and he's running into it now.

Is it luck, you say!?

"Xu Luo, how likely do you think your reasoning is?" After Liang Bin sighed, he realized that he was a little out of shape, so he changed the topic.

Although the idea proposed by Xu Luo may exist, he has already figured it out, but this is not substantially proven, it is just a guess.

What if it's just a coincidence?

You must know that the serial murder case and the four murder cases that killed four people in a row are not a heavyweight at all, and it is impossible to settle it because of speculation.

Xu Luo's discovery was not enough for him to change the direction of solving the case!

Hearing this, Xu Luo frowned.

He naturally has the evidence, but now the time is right, and he doesn't want to say it directly.

"Team Liang, I think there's another thing you should focus on right now!"

"What!?"

"Next kill!"

Xu Luo swept around everyone's faces and said, "If my reasoning is correct, this is a serial murder case, and the murderer is indeed killing according to the concept of the seven deadly sins, and there is a specific order for killing!" "

"So..."

Hiss~~

Before Xu Luo finished speaking, everyone had already reacted, and a chill rose behind them.

Liang Bin instinctively shouted:

"It's rage! Eat one's heart out! Arrogant! "

"He'll kill at least three more people!"
