Gu Junwei turned his head and glanced at Su Yun, meaning that he wanted to take a look?

Su Yun looked at Lu Chenglin, who had a fanatical face, and smiled.

Such a person who is obsessed with solving the case wholeheartedly is also cute, and she can't see that Gu Junwei cares about this case very much, but subconsciously puts her and the two children in the first place.

She nodded to Gu Junwei, and Lu Chenglin's face was immediately full of joy, and he offered to ask Gu Junwei to say anything, so that he could let the soldiers he brought to escort the little Langjun and the little lady in the mansion back.

Gu Junwei directly ignored Lu Chenglin, recruited secret guards, and asked them to go to the General's Mansion and let Qinglai personally come over and bring the two children home.

Lu Chenglin didn't care, it was a big surprise for him to be able to pull Su Yun and Gu Junwei to participate in this case.

So he accompanied Su Yun and them without complaint and waited for the people from the General's Mansion to arrive, during which he told them in detail about the case.

"The first case happened five days ago."

Su Yun was slightly stunned.

The first case happened five days ago, the day after she returned to the General's Mansion.

This means that if all four of those cases were committed by the same murderer, he would have killed four people in just five days.

What is the purpose of such a dense frequency?

"The deceased in the first case is called You Er, 16 years old, a native of Xu County, Fengzhou, who went to Beijing to participate in the martial arts examination with the first result in the township examination, and was righteous and generous.

His father is a county magistrate in Xu County, Fengzhou, and his family is not a big family, but his family is also passable, so he often invites his friends to go to the tavern to drink at night, and he drinks all night.

He was found dead in the back alley of the tavern where he had been drinking that night at about 7:15 a.m., and the cause of death was a knife in the throat.

There was no trace of the murderer at the scene, there was nothing unusual about the deceased except for the fatal wound, no other wounds, and the clothes he was wearing were identified by his friends, as they had been when he left the tavern at about 6 a.m. ”

"The second deceased is named Ming Wenwen, 37 years old, a native of Hongnong County, Xinzhou, who also passed the township examination and came to Beijing to participate in the martial arts examination, and his results were average.

He already has a wife and children in Xinzhou, and his family has been farmers for generations, and he has been immensely powerful since he was a child, and because he is interested in martial arts, he has specially studied martial arts.

But his reputation in Hongnong County is not good, he often bullies, likes beauty, often goes to the Qinlou Chu Pavilion to look for flowers and willows, but he owes money.

He was found dead in a small alley in Dongshi that few people pass by around 4 p.m. four days ago, and the cause of death was the same as You Er's, he was cut in the throat with a knife, and he died very cleanly, with no unnecessary scars on his body, and his clothes and accessories were very neat. ”

Su Yun couldn't help but smile.

died cleanly, and the word Lu Chenglin is also interesting.

"The third deceased is named Tang Dahe, 30 years old, from Licheng County, Bianzhou, who was recommended by the local garrison generals to come to Beijing to participate in the examination.

The character is honest and simple, he is a well-known good man, and he has been preparing for the exam very calmly since he arrived in Beijing, and he is not like other candidates to get around and make contacts.

He was found dead in the alley behind his hotel at around 2:30 a.m. (7:30 a.m.) two days ago, with a bag of xiaolongbao on the ground, presumably killed on his way back from buying breakfast.

The cause of death was the same as the first two deceased, and the scene and the deceased were very clean. ”

"The fourth deceased is Shi Mingyi, who died today, 21 years old, from Fanyang County, Weizhou, who was also admitted to the township examination to participate in the entrance examination, and his grades were above average.

The family is a big family in Fanyang County, the family is wealthy, shrewd, utilitarian, as soon as they arrive in Beijing, they will visit the magnates in Shangjing, but their family can speak a few words in Weizhou, but almost no one knows them in Shangjing, so they hit a wall one after another.

He was found dead in the back alley of the Jade Building at the second quarter of Shen Zheng (4:30 p.m.), and he left the Jade Building at about 3:45 p.m. (3:45 p.m.), so it can be assumed that he died between the 3rd quarter of Shen Shi and the 2nd quarter of Shen Zheng this afternoon.

The cause of death was the same as the first three deceased, and the scene and the deceased were still very clean. ”

After listening to this, Su Yun understood what Lu Chenglin had just told her.

The same characteristics of the deceased are almost the same except that they are also martial arts candidates and have the same method of death.

There is a big age gap between these four people, and they are all from different places, so it is not an exaggeration to say that they are from all over the world.

The personalities are almost completely different, except for the Ming scriptures and Tang Dahe, the net worth backgrounds of several people are also different.

And there is nothing special about the way of death, a knife cutting the throat, it is like death, the purpose is just to harvest life.

As Lu Chenglin said, the murderer seems to kill for the sake of killing.

The locations are almost always dead in alleys far from the crowds, which is nothing special, and it is impossible to kill people in the street.

Dying in the alley is the place where there is nothing to analyze, simply to avoid the crowds.

After listening to this series of words, there is really nothing special about this murderer, if Su Yun wants to describe it in one word

Killing machines.

He is like a killing machine, and there is only one instruction to enter, which is to kill the candidates for the martial arts exam.

Su Yun pondered for a moment and suddenly smiled.

In fact, it is not completely without analysis.

She has always believed that the most perfect crime in the world is the simplest crime.

The fewer steps, the less evidence is left.

The ideal crime is to approach the victim, kill, and leave.

But the problem is that whether it is a murderer or a killed, they are all people with seven emotions and six desires.

If you are a human, you can't really be like a machine, mechanically fulfilling instructions.

The killer will have his own demands, and the killed will have his own emotions.

This case seems very simple, but such simplicity only sets off its complexities more.

Seeing the smile on the corner of Su Yun's mouth, Lu Chenglin chuckled in his heart, God, could it be that she has already found something unusual?

Because he had followed Su Yun to investigate the case, Lu Chenglin was also influenced by her, paying special attention to the behavior trajectory left by the murderer and the deceased at the scene, and analyzing their psychology in this way.

Sure enough, he is worthy of the master he believes in his heart!

Seeing that Su Yun was about to speak, Lu Chenglin hurriedly said: "Wait a minute, madam, I actually have some opinions of my own, I don't know if Mrs. can help judge and judge." ”

The man in his forties looked at her with a modest and nervous expression, like a child in the school waiting for his husband to judge his work.

She couldn't help but laugh and said, "Please Lu Qing say it." ”

Gu Junwei looked at her radiant appearance, and unconsciously hooked the corners of her mouth slightly.

Finally seeing her like this again, it doesn't seem bad to be able to make her so happy, and it doesn't seem bad to take her to this case.

Lu Chenglin's eyes lit up and said, "First of all, there is a very strange thing about this case, the scene and the deceased are too clean. ”

Su Yun raised his eyebrows.

This shows that the deceased knew the murderer, at least, they had no defense against the murderer at all, and the deceased were all martial arts candidates with high martial arts, if it weren't for the fact that they did not defend the murderer, the scene and the deceased could not be so clean.

So I reasoned that the murderer was either someone whom the four deceased knew in common, or, in their opinion, someone who posed no threat to them at all, a woman, an old man, or even a child.

But judging from the murderer's throat-cutting technique, no matter what his identity is, he should have a certain amount of martial arts, and it is impossible to be completely harmless. ”

"Secondly, the time of their deaths is in the morning or afternoon, which means that this is the time of murder that the murderer prefers, but what is the reason, I haven't thought of it for the time being."

"Finally, and the biggest doubt in this case, why did the murderer only choose martial arts candidates as victims?

Is it because he has had some bad or even unbearable memories because of martial arts, is he a candidate who has failed in martial arts, or has he been hurt by people who participated in martial arts? ”

The more Lu Chenglin said that his confidence became weaker, and even he knew that this was not so much an inference, but rather a process of inference.

He found the suspicions, but he didn't find the direction to break them down at all!

Su Yun smiled and said, "You did a good job." ”

Criminal psychoanalysis should have been a completely new thing in ancient times, but listening to his inference, he has at least already started, and with his enthusiasm for solving crimes, given time, he will definitely not be worse than her.

Hey? Could it be the credit of her cultivation?

Su Yun coughed lowly, retracted his thoughts, and said, "But you just made a big mistake, and you are still stuck in the traditional ...... Well, in the previous criminal investigation methods, the first focus was on the clues found at the scene of the murder, and the truth was deduced from the clues.

However, the criminal mind, the first thing to pay attention to should be the psychological characteristics of criminals, starting from their psychological characteristics, to find the truth.

And of all the information you just mentioned, you completely ignored the suspicious point that best revealed the psychological characteristics of criminals. ”

Lu Chenglin was stunned for a moment, but he didn't have the slightest annoyance, and asked with his eyebrows: "Please give me advice!" ”

Su Yun raised the corners of his mouth, his eyes revealed calmness, and said: "In the past five days, the murderer has killed four people, and they all killed one a day, but why, only on the third day, he didn't do it?" ”
