Foreword: Do you know what psychological sin is? Before we know psychological sin, we need to know what psychology is, and according to the written explanation, it refers to the study of the laws of the occurrence, development and activity of psychological phenomena in animals or people....... Those explanations are too official to understand, to put it simply, people with mental illness do not think very differently from ordinary people, and we can roughly summarize this phenomenon as he has psychological problems. Pen? Interesting? Pavilion wWw. ｂiquge。 infoI don't know much about psychology, so I'll just give a small example here and won't explain much. Psychological sins are a series of sins committed when the mind is not sound. Imagine a nurse with a familial genetic recessive psychosis working in a hospital with her condition hidden; Or what happens when a mentally ill police officer commits a crime and he doesn't know it?

"An important piece of news inserted below: the chemical plant explosion that occurred in March 2010 has finally made leaps and bounds after nearly five years under the unremitting tracking of the police, the criminal Liu Huo was arrested in Hong Kong on April 3, 2016, according to the police, the man had infiltrated the factory to disrupt the monitoring equipment and then sneaked into the factory meter to plant a miniature bomb...... "The TV has been repeatedly playing yesterday's news about the explosion.

On the floor sat a man with messy hair and a stubble on his face and the smell of alcohol, in an eleven-square-meter attic room, surrounded by different brands of cigarette butts and empty beer bottles, this man was Wei Hui, the police officer who solved the "chemical factory bombing case". Wei Hui, who graduated from the police academy in 2002, easily became a people's policeman with excellent grades, but his ideal was to become a criminal policeman. So after several years of diligent work and a lot of contributions, after countless applications to the above for transfer, it was not easy to be transferred to the criminal police team, but unfortunately his luck was not good, his boss was a dead fat man who could eat and prostitute, his father was the director, and his mother was the daughter of a wealthy businessman of a company, in short, the family background was strong. Wei Hui has always been summoned by him, not to mention, the fat man finally shamelessly robbed Wei Hui of the case that he had worked hard to solve for many years! ......

Jingle bell bell ~ The phone rang "Hey! Who is it?! Another man's voice came from the other end of the phone: "Where are you, we've been looking for you for a long time, and the bureau is holding a celebration banquet, and you're the only one left!" "This case is obviously solved by me Wei Hui, don't you know, what did the fat man do?" Don't you know that?! The voice on the other end of the phone suddenly became smaller, "Yes, yes, we all understand, but now the media thinks it's the credit of the fat man, isn't it okay for you to be a little minion, so it's better for you to come first... Let's think about what else we can do, let's see ......" "Dudu Dudu......" Wei Hui hung up the phone angrily and said angrily, "Cut! What a friend. ”

.......................

At half past six in the evening, the supermarket vegetables in the fifth district of Fourth Street were half discounted, and Wei Hui walked on Fourth Street. For this cheapness, he always stayed up until seven o'clock in the evening to have dinner, and had to cross two streets to get to the supermarket. Just as I was waiting for a red light at an intersection, my phone rang again.

"Jingle Bell~"

"Hey! What for!? ”

"Wei Hui, I'm still unhappy about what happened before, be happy", the person on the other end of the phone was still the same person in the morning.

"Tell me something quickly, I'm not in the mood to listen to your nonsense."

"Okay, okay, no one has taken a case here, do you want to take it?" The other party's voice became serious, "It's a bank robbery, it happened last night." Because it's a small bank, it's not listed in the newspaper, and there are no casualties...... It should be much simpler than the last time you were at the big bank, and if you're going to take over for a while, I'll send you more detailed details. ”

"This ......." Wei Hui stopped, looking a little hesitant.

"Anyway, you're idle now, little case, just take it"

“...... Alright then, you can send it to my computer......"

As soon as he hung up the phone, a white van rushed past Wei Hui at a red light, and suddenly the circle mark of the yellow bee printed on it made him feel very familiar, as if he had seen it somewhere, but he had no impression at all. The license plate is also very special, XA2022. It wasn't until there were only six seconds left in the green light that he came back to his senses and hurriedly crossed the street.........

At half past seven, I received a call as soon as I sat down when I got home after buying vegetables, "Wei Hui, I forgot to tell you just now, after this case is completed, Lao Wu has found you a partner, and the foreign one is a big beauty!" ... Ahem, the boss is coming, so that's it. Silently hanging up the phone, Wei Hui turned on the computer, "............ Three robbers from. Find. Head. Come. See. Two. Man. One. Female." Wei Hui looked at the information and read it slowly word by word, but it didn't take long to hear the landlady's hurried knock on the door, "Knock knock!" ”

"Wei Hui, I saw you go in just now! Open the door!! ”。 In desperation, Wei Hui had no choice but to open the door, "You kid really makes me look for it, I have to pay the rent today!" You already owe me two months of rent!! The landlady yelled at Wei Hui at the top of her voice, and savage shouts echoed throughout the corridor.

"Mother Wang, I only have this money here...... You see....I can only pay last month's rent, next time! Next time, I will even give you this month's money, the last time" Wei Hui took the landlady's hand and tried to squeeze out a tear, "That's what you said last month, you think I'll believe you, hum!" You weren't so poor that you shouldn't have rented your house back then! The ghost believes that you will be able to pay it off next month for no reason", "You have to believe me this time, I took on a big case this time, and I will be promoted in a short time, another month!" Just one month!! ”“…… Okay, but the ugly words are in front, this is the last time, it's really a poor three, it's bad luck for the old lady! "The voices of Wei Hui and the landlord attracted many residents, and they didn't dare to step forward, so they could only sneak their heads out of the house to watch the excitement." What to see! So do you want to live if you don't do anything!? Do you still have to pay the rent?! The landlord turned around, waved his hand, and roared, and everyone rushed back in shock.

"Alas......" Wei Hui closed the door when he saw that the landlord was far away, wandering in a foreign land with a dream, in addition to paying rent every month, he had to pay water, electricity and gas, and send some money back to his hometown to his parents. However, he can only continue to work his way up the ladder to keep him alive in the big city. Wei Hui returned to the computer, and after reading all the information, he soon found that the bank robbed by the robbers was covered with surveillance within twelve kilometers, and there was only one way down, and he could check the surveillance according to the direction of the suspect's escape to find their final destination. After Wei Hui got this discovery, he immediately called his colleagues at the police station, "Datong, I don't care what you try to find all the surveillance near the bank and transfer it to me!" "Okay, yes, but it's ten o'clock now, so I'll give you all the surveillance footage by noon tomorrow at the latest", "Thank you". hung up the phone, the corners of Wei Hui's mouth rose 45 degrees, "Heh, it's really a simple case"

Ten twenty o'clock. Wei Hui, who was finishing the shower, was about to go to bed when he heard the little girl on the second floor preparing for the violin competition, and it didn't take long to hear the landlady scolding from the first floor: "It's noisy!" Do you want to sleep! As soon as the words ended, the piano stopped. This building is full of migrant workers from other places, everyone will delay the rent for half a month or a month or two from time to time, almost everyone lives in dire straits, Wei Hui is lying on the bed, even if he wants to hold the little girl, he can't do anything.

.........

Early the next morning, the sound of a police car came from downstairs, and Wei Hui casually put on a white shirt and opened the door, "Team Wu, why are you here?" Team Wu stared at Wei Hui for a short time and said in surprise, "Wei Hui? Do you live here? Wei Hui straightened his shirt, "That's right, I live here, what's wrong?" What happened? Team Wu sighed, "Yesterday at half past three in the morning, the landlord Wang Huixia was killed, and she was killed with a knife......"

Wei Hui was shocked and at a loss when he heard this......

"Team Wu! What's going on, how was it fine yesterday, how can it be ...... today" Wei Hui's eyes stared straight in the direction of the coroner at the scene.

"Xiaohui, it's not easy for you to get involved in this matter, after all, it's your landlord who died." , Captain Wu took off his dark brown leather jacket, "Your place is really stuffy~ hehe." That one...... He Jie! Come and introduce you," Team Wu hung a leather jacket in his left hand and pushed Wei Hui in front of a small girl with his right hand, "Xiaohui will introduce you, this is our new on-site explorer He Jie, He Jie, this is the "old man" Wei Hui in our team, He Jie She was transferred back from the American school, and you will be partners in the future."

"Team Wu......" Wei Hui pulled Captain Wu to the corner and whispered, "I don't need a partner."

"That's what it means from above. I think she reads a lot of books but doesn't have much experience, although you are also a good school graduate but relatively worse than her, but you have more experience and can complement each other, you are so self-conscious, isn't it more convenient to have a partner than yourself? ”

"I see, I'll go now".

Captain Wu hurriedly grabbed Wei Hui's hand, "Hey, wait, Wei Hui, you can't get involved in this case", Wei Hui asked confusedly, "Why, I don't have anything to do with her if I am not an immediate family member." Team Wu patted Wei Hui on the shoulder, "I know, when I heard that you just had a dispute with Wang Huixia over the rent some time ago...... I can't help it,...... However, "Captain Wu put on his leather jacket again, "You can ask He Jie about the situation at the time of the crime, and help her by the way when solving the case, you understand?" ”。“ Well, thank you Team Wu" ......

Wei Hui walked up to He Jie and asked, "What did you find?" ”

"Most of the corpses appeared corpse spots, the lips began to wrinkle, and the pupils were still reacting, and it was speculated that the time of death should be between one and two o'clock in the morning today."

"That's it? Learned from books? Wei Hui raised his eyebrows and glanced at He Jie.

"Do you have any comments?" He Jie heard Wei Hui say this and looked up at him.

"The time of death you speculated based on the corpse spots is logically correct, but unfortunately, the weather was very hot a few days ago, so the time should be pushed back by one to two hours, and the specific time of Wang Huixia's death should be between three o'clock in the morning and half past one o'clock in the morning." Wei Hui knocked on He Jie's record board and said with a smile, "You can't accurately find out the murderer just by relying on the knowledge in books." ”

He Jie looked at Wei Hui for a long time, she thought to herself, this seemingly rough man who lived in the tube building could actually educate herself on professional issues, and suddenly, she was full of curiosity and admiration for this man.

"The cause of death? What about the murder weapon? What clues have you found? Wei Hui looked around the room and returned to He Jie's side, "Team Wu told me that Wang Huixia was killed by slashing her throat, but I saw traces and blood stains on the window just now......

"That's right." He Jie said, "The direction in which the body fell to the ground was towards the door, and I didn't think something was right, so I had already asked a colleague to bring the sample back to the bureau for testing." ”

"Good. Wait a minute.... This is ......." Wei Hui squatted down beside the corpse, "He Jie, come and take a look, this.... Is it strangulation? He lowered his head and pointed at Wang Huixia's neck, there was a purple bruise mark under the deep knife marks, and if you didn't look carefully, you really couldn't see the strangulation marks under the knife edge.

"Why are there two traces? Could it be that the murderer tried to strangle Wang Huixia's neck with something before using it? But.... Why? Because it failed? What did he use? ......" Wei Hui muttered to himself as he looked at the strangulation mark.

"What's it for? Aren't they all ropes? What else can be used? He Jie looked at Wei Hui with puzzled eyes.

"If you look at this trace, it is generally said that the scars that have been strangled by ropes are basically more than ten centimeters, look at this ...... Don't you think this trace is too short, the murderer must not have used a rope. Wei Hui touched his chin and stood up, "Write it down, see if there are any deformed hard strips in this room, in the corner, under the bed, behind the TV, and in the trash can, it may be made of volatile material, you can check it." ”

"I see." He Jie turned around and remembered something just a few steps, and suddenly turned back to Wei Hui and said, "By the way, let me tell you, they checked the surveillance on the side of the street, and no one has entered or exited from the main entrance, so they may interrogate everyone in this building, including you." ”

"No problem. I'm going to the bureau in a while, let's interrogate them~" Wei Hui shook his clothes and strode out of the door.
