criminal profiling

Xu Xie rubbed his ears. The ears damaged by the high decibels have not fully recovered yet, and he always feels the sound of "Weng Weng" ringing in his ears.

Even though he is so small, but can make such a sharp voice, Xu Xie once again had a clear understanding of the saying "a person should not be judged by his appearance".

The frightened girl was sent home by Zhuang Sheng himself, and told her not to walk home alone at night.

The people from the Heng County Police Station took the man away and attempted to kill him. This crime alone is enough for him to drink a pot.Besides, it's easier to pry a man's mouth open with this as a guide.

Zhuang Sheng didn't intend to stay any longer, and after explaining some follow-up matters clearly, he planned to rush to Lingbei County overnight-after all, the last remaining person is the most troublesome.

It was the middle-aged policeman who sent Zhuang Sheng away, his face was more gloomy than when Zhuang Sheng came, Xu Jie had already seen that this man was not easy to deal with, so he avoided it.

When Zhuang Sheng was about to get in the car, the middle-aged policeman finally spoke.

"Officer Zhuang, it's because I don't know Taishan with my eyes. When you first came here, you had a bad attitude. I apologize to you." He bowed to Zhuang Sheng after he finished speaking.

Zhuang Sheng was caught off guard by his bow, and his reaction was delayed by half a beat. When he came back to his senses, the middle-aged policeman had already bowed.Zhuang Sheng pursed his lips, supported his arm and lifted it up, looked at the face with a stiff expression because he was not good at doing these things, and said seriously:

"Officer Li, I can probably understand your thoughts, and you don't have to apologize for it." After a pause, Zhuang Sheng said calmly, "If I'm really what you think, and I have nothing to do to make trouble, you don't have An apology is necessary; and if I solve the problem and prove myself, I don’t need your apology.”

The implication is that since the fact has already slapped you in the face for me, there is no need to apologize again.

Are these words of consolation, or sarcasm?

The middle-aged policeman looked at the car going away, lost in thought.

Park trails.

It was the weekend, and many people came out for a walk early in the morning to relax.Some are old men supporting the old lady, some are couples holding hands, and of course more are parents with children.

An old lady with a basket of freshly picked apricot blossoms.There is a disabled son in the family, and the old lady comes out with a basket every day to sell flowers to subsidize the family.Flowers are not very easy to sell today, because most of the people who come out to play on weekends are families.

The old lady walked to the path behind the rockery with a basket on her shoulders. She was a little tired and wanted to go to the pavilion over there to rest.

When approaching the stone arch of the rockery, the old lady stopped and beat her legs. As soon as she looked up, she saw a tall man in a sweater and hat approaching her.The old lady didn't wait to see what the other person looked like, she habitually put on a smile and went forward.

"Handsome, do you want to buy flowers?"

The other party didn't seem to hear her words, lowered his head slightly, and passed her by without stopping.

The old lady felt a little disappointed, but it was only a little bit, after all, she was too used to such rejection.While arranging the flowers in the basket, she thought about the scene just now and felt that there was something strange about it. After thinking about it for a while, she couldn't figure it out, but her eyes froze when she looked at Lanzi.

—In the basket, on the white cloth used to cover the flowering branches, was a red note.It seems that a branch of the apricot blossom has also been pulled out, because a branch of the white cloth was lifted up.

Heck, she sells a flower for three yuan at most, and this 100 yuan is enough to buy all the flowers in the basket.

The old lady became anxious immediately, and turned around to go after the person just now, but when she turned back to look for it, there was no sign of him.

Just then, there was a scream up front that was heard by almost the entire park.

On the stone slab beside the rockery, a young woman lay sideways on it, her body slowly soaked in blood.The bright red blood kept flowing, dyeing the grass next to it red, forming a small pool of blood.

The police soon arrived, the park was cordoned off, the two people who found the body were left behind, and everyone else in the park was questioned one by one.

Knowing that someone died in the park where they had been playing, or was stabbed in the heart with a knife, the tourists in the park were a little panicked.When asked if he saw any suspicious person, everyone became suspicious at once.

When the park management staff cooperated with the police to clear the park, another body was found in the park toilet.The deceased, a male, was also stabbed in the heart and died.

——The difference is that there is a fresh apricot blossom on the chest of the deceased.

"Oh, that young man is a good man. Seeing that I am old and pitiful for selling flowers, he put 100 yuan in my basket without a word. Although I am old, I can still move my hands and feet, and I can make money by myself, but it is not for nothing. I want money from other people. But I am an old man, how can I catch up with him. If you see him, can you help me return the 100 yuan to that young man?"

The old flower seller was questioned by the police. She sells flowers in the park every day. There are so many people coming and going in the park every day, but she doesn't know what is suspicious or not.But receiving 100 yuan today is a big deal for her. After all, it is almost a week's income for her, so she can't help but say it.

"Buy flowers? He bought your flowers?" Zhuang Sheng, who just came back from the park toilet, couldn't help asking when he heard the old lady's words.

The old lady was talking to the police. When she heard the voice, she looked up and saw a pretty young man. She said in a kind tone, "It's not for buying. Those costs are worth 100 yuan. The young man gave me 100 yuan because of his kind heart."

Zhuang Sheng didn't argue with her, and asked again: "Then do you remember, did he walk by your left or your right?"

The old lady was in trouble, "Left and right? I can't tell the difference either."

Zhuang Sheng thought for a while, and asked the old lady to stand up with the basket on her shoulders. He stood opposite to demonstrate the situation.

"Did he pass this way, or this way?"

"Hey, this way, I'll understand after you do this once."

Standing on the left hand side of the old lady, Zhuang Sheng reached out to pick up a flower from her basket, "He put 100 yuan in the basket and took away an apricot flower at the same time. Did you notice any difference at that time?"

"It's not the same? What's the difference? Oh, there seems to be something red flashing, I'm not sure, maybe it's because I'm getting older."

When Zhuang Sheng finished his questioning with the old lady, Shi Ke walked over with a gloomy face and stood with him.

"That's him, right?"

Zhuang Sheng nodded silently.

"There are still two people this time, but they were killed separately. Does he kill two people every time he commits a crime?"

Zhuang Sheng shook his head silently, and said in a low voice, "I'm afraid not. If he kills two people at once, with that person's skills, he can attack two people at the same time. There is no need to commit crimes separately."

Shi Ke was a little annoyed, "Then what is his intention in doing this?"

Zhuang Sheng lowered his eyes, and his voice became lighter, "I'm afraid this is one of the rules."

"Rules? What rules?"

"The number of people is not counted, but the number of crimes committed. On the first day, one crime was committed; on the second day, two crimes were committed."

Shi Ke's eyes widened when he heard this, "So on the third day, did you commit three crimes in a row?"

Zhuang Sheng looked at him. Although there was no expression on his face, Shi Ke always felt that there was a meaning of "you think too naive" in it.

"Maybe it's not an arithmetic progression, but a geometric progression."

Shi Ke blinked his eyes, whether he understood or not, he would be good at mathematics if he could do the four arithmetic operations, and such things as arithmetic and arithmetic were beyond his ability.

Zhuang Sheng didn't continue to explain, but said solemnly: "It's not important, what's important is that maybe this is just the beginning."

News came from Heng County that the man who was caught had been recruited.

He and his wife opened a family workshop to extract oil. They have a nine-year-old son and lived happily ever after.Unfortunately, my son got leukemia two years ago, the family savings were exhausted, and the oil mill was sold, but the son's illness did not improve and continued to deteriorate.

If there is no more money for medical treatment, he can only watch his son die.The man borrowed money everywhere, knelt down to others, and only borrowed less than three thousand in half a month.In desperation, someone came to him and said that he could give him money, and not borrow it, but let him "earn" it himself.

"Kill a person and give [-]. No matter who, as long as I kill someone, I can get [-]. Why don't I do it? I don't regret dying, but my son is less than ten years old. His grades are so good. In the future, he will definitely give me [-] yuan. He is more promising than me. Exchange my life for his future, such a good deal, why don't I do it? Anyway, no one else can help me. "

The man showed no remorse in his confession. Even though the murder made him feel uncomfortable, he was burdened with heavy pressure and psychological burden, he couldn't sleep at night and had nightmares again and again, but he still didn't feel any regret.

The man finally said:

"I only hate myself for being useless. I only killed one person before being arrested. If I can kill a few more, I will have money for my son's medical treatment. If that is the case, I am willing to go to hell."

Among the three senders, one is a bastard with a boring mind, one is a father who treats his seriously ill son, and the other is a real killer.Whether the motive for the killing was instigated by others or for money is still unclear.

But judging from what we know so far, it can be confirmed that there are people behind the scenes manipulating this.

"It won't be—that person again?"

Shi Ke's expression was a bit indescribable, after all, he followed him and didn't even touch a piece of his clothes.Although I heard that the man was being hunted all the time and fled everywhere, he was very embarrassed, but he always managed to escape in the end, and even the Chinese and foreign police became a laughing stock.

Zhuang Sheng didn't know what he was thinking of, so he didn't speak.

Thanks to the lessons learned from the past, the three counties have set up a net around their respective post offices.The image of the killer has been exposed. If he dares to show up at the post office to deliver letters again, the policemen who are all around will rush out and take him down on the spot.

According to the previous law of changing places for one crime, the killer is likely to choose Songquan County this time.So Shi Ke and Zhuang Sheng both rushed to Songquan County.

There is only one post office in Songquan County, which is more convenient for deployment and control.only--

"Will the murderer really show up again? Idiots also know that the police will monitor the post office, and if they send letters again, wouldn't they fall into a trap?"

Xu Jie was sitting in a van more than ten meters away from the post office, muttering to himself while staring at the door of the post office.

The staff at the post office have long since been replaced by police officers, and there are also plainclothes customers pretending to be in several nearby shops—in fact, Shi Ke wanted to replace everyone, including the boss, but Zhuang Sheng did not agree.

"The killer may be able to guess that the police will monitor the post office, but he can't be sure, let alone the scope of the control and the tightness of the net. If he is not sure of these, he will not be able to take effective precautions."

Judging from the fact that the killer chooses the local post office to deliver letters every time he sends letters, he may have a certain degree of obsessive-compulsive disorder.And with the cautiousness of this killer, even if he delivered a letter, he would scout the environment in advance.If he sees that all the shops around him have changed people, it is not certain whether he will choose to throw himself into the trap again.

Shi Ke agreed with Zhuang Sheng's suggestion, and in order to appear natural, the police stationed in Mingmian would also be replaced after a period of time - otherwise a bowl of noodles would be eaten there for several hours, and a fool would not be able to see that there is a problem .

From morning to noon, and until the sun was about to set in the afternoon, the killer never appeared.Some people think that the killer knew that the place was being monitored by the police, so he would not appear again.

Just when Zhuang Sheng was also wavering, not sure if the killer would come, a tall man in a black sweater and hood appeared.He looked very ordinary except that his clothes were relatively clean, and a grown man wearing a sweater hat looked a little strange, like an ordinary passer-by.

The man put his hands in his pockets and walked with his head slightly lowered, as if he didn't care about the surrounding environment at all.He walked straight to the post office, and when he was two or three steps away from the mailbox, he stopped suddenly, turned around slowly, and pulled his hand out of his pocket as if holding something.

Shi Ke stared intently, holding the walkie-talkie in his hand, watching the man's movements without blinking.

The man pulled out a white envelope from his pocket, and instead of putting it in the mailbox, he raised his hand in the direction of Shi Ke and the others.

"He knows we're here." Shi Ke said with a frown, paused, and now he didn't have time to worry so much, and gave orders on the intercom.

"action!"

I'm sure it's this man. At this time, no matter what tricks he has, the hundred and ten people here can let him fly away with wings.

Zhuang Sheng remained silent after seeing the man appearing. No matter how he looked at it, this man fit the profile of the killer.Zhuang Sheng also believed in his own judgment, but there was always some lingering weird feeling.

People poured out of the nearby cars and surrounding shops, surrounding the man standing next to the mailbox.

"Don't move, raise your hand!"

Even though he was surrounded by the police with guns, the man did not show the slightest panic.He raised his head, showing an indifferent face, and swept across the crowd indifferently, then fixed his eyes on Zhuang Sheng behind him.

"Are you Zhuang Sheng?" Perhaps because he hadn't spoken for a long time, his tone seemed a bit weird, and his voice was hoarse and deep.

"I'm Zhuang Sheng." Zhuang Sheng nodded, and took two steps away from Anthony's hand. For some reason, the strange feeling in his heart became stronger and stronger.

The man pulled the corner of his mouth as if he wanted to smile, but his facial muscles were stiff, which made his smile a bit ugly.

"Very well, I don't need to send you the letter."

After the man finished speaking, he shook the envelope vigorously, and the snow-white envelope flew towards Zhuang Sheng like a paper airplane.

"What are you doing, put your hands up!"

"Don't move!"

"Arrest him!"

The man's actions caused a commotion, and the police surrounding him moved towards him.He didn't move, but he didn't raise his hand, and his other hand, which was in his pocket, never came out.

A flash of inspiration flashed in Zhuang Sheng's mind, and he suddenly thought of something. He pushed Anthony away forcefully, and shouted at Shi Ke:

"Don't get close to him, back away!"

Before the words were finished, there was a violent explosion. In the light of the fire, the strong shock wave blew up the mailbox next to it, and the human body was blown into pieces.

Zhuang Sheng couldn't see anything, because at the first moment, the people around him threw him to the ground.

Painful wailing was everywhere in my ears, the glass of the car was shattered, and the alarm sounded non-stop.At the center of the explosion, the shattered corpses were still burning.

Zhuang Sheng pushed away the person who was pressing him, and Anthony let him go and stood up.He suffered some injuries to his back, but this level was nothing to a person like him. On the contrary, he was glad that these injuries did not appear on Zhuang Sheng.

Looking at the messy scene full of wailing, Zhuang Sheng tightened his mouth and said nothing.His eyes swept over those injured people, and he saw Shi Ke also fell to the ground with a lot of blood on his forehead, but luckily he was awake.

Just as he was about to take a step, he saw the envelope at his feet. The white envelope was stained with someone's blood.

Zhuang Sheng bent down to pick up the unsealed envelope, and pulled out the playing cards inside.

Specially made poker cards, the front is a heart K suit pattern, the back is a blood red background, printed with two lines of white lettering.

The above line reads:

"Since life is so boring, why don't we play games."

The following line, in relatively small characters, reads:

"It's dark, please close your eyes."
