Miss Qiao, are you all right?

After returning to the police station, Qiao Shiyi went directly into the office, retrieved the information of the deceased, and checked carefully, not missing any details.

The deceased Ye Lin, female, 21 years old, a third-year student at the Foreign Languages ​​College of this city, from a wealthy family...

After Qin Qianshu followed Qiao Shiyi back to the office, she stood behind her and watched her check Ye Lin's information over and over again. Coupled with the reaction in the bar just now, she had a bad feeling. premonition.

"What's the matter? Why did you insist on taking over Ye Lin's case from Police Officer Feng?" Qin Qianshu heard from Long Boyan that the relationship between Qiao Shiyi and Police Officer Feng should not be very good, and couldn't help worrying about her. Because Qiao Shiyi's doing so was undoubtedly slapping the third team in the face.

Qiao Shiyi rubbed the space between her brows wearily, and said with a heavy voice, "Jin Yuan's case and Ye Lin's case are related."

"Hasn't Jin Yuan's case been solved? And the murderer has already been sentenced, how could..."

Qin Qianshu was still a little puzzled, Qiao Shiyi thought about it, and took out the phone from his pocket, and handed Qin Qianshu the photo he took on the door of the toilet cubicle.

"This number...isn't it..." Qin Qianshu was a little surprised, because this string of numbers was obviously written by the same person as the string of numbers in the forest farm last time.

"That's right, this string of numbers was found at the scene of the two murders. The previous number was 'I am the murderer', and the number found today is, 'I'm here'. So, according to the results of the previous case, I deduce that these people must have been instigated by the same person to commit crimes."

"Is that why you took this case?" Qin Qianshu felt that the matter was getting more and more complicated. He abetted the murder, and he didn't have to do it himself. Even if he was found out, he could still be killed.

"Judging from the figures left by that person, his education level should not be high, and the figures written crookedly look like elementary school students, but he must have excellent eloquence, otherwise, it is impossible to speak words that can motivate others to commit murder.

He must be a cynical person, full of hatred for this society, because he lives among the lower classes, envies the lifestyle of the upper class, and complains from time to time.

I don't know when it started, this kind of verbal complaints could no longer calm down the hatred in his heart, so he began to look for people around him who were in despair like himself, and used extremely desperate descriptions to drive people into the abyss, and then took another step. Lead them to kill one step at a time..."

Qiao Shiyi talked more and more deeply, but Qin Qianshu couldn't listen anymore.

"Stop, officer Joe, these are just your personal guesses, don't get too involved, okay?"

Qiao Shiyi was interrupted, a little unhappy, she looked up at Qin Qianshu who was also frowning.

"You don't believe my reasoning?" Qiao Shiyi was full of doubts, which made Qiao Shiyi very unhappy.

"No... It's not that I don't believe it, but now that the two cases are superimposed, you can't just rely on deduction to solve the case, can you?" Seeing that Qiao Shiyi was unhappy, Qin Qianshu regretted talking too much.

Qiao Shiyi was silent for a while, then stood up and packed her things: "I will start the investigation tomorrow, and I will prove to you that my inference is correct!"

After finishing speaking, Qiao Shiyi glanced at Qin Qianshu, turned and left the office.

Qin Qianshu watched Qiao Shiyi leave just like that, feeling a little helpless, this guy really hasn't changed at all!

----

At the beginning, when Qin Qianshu was in the police academy, he heard of Qiao Shiyi's name just a few months after the start of school.

In the inference class, I used my own thinking to infer a well-known puppet hiding corpse case at that time, and analyzed the psychology of the perpetrator with the fastest speed and no error, which was appreciated by the professor and classmates.

Since then, Qiao Shiyi has become famous in the police academy, which made Qin Qianshu very curious about this person, but after actually seeing him, he found that this person was really just like that, ordinary and boring, but Not long after, Qin Qianshu realized that she was wrong.

After returning to the police academy during the National Day holiday, the school announced a shocking thing: the body of a boy in a certain dormitory was found in the closet by his roommate who came back from the holiday.

However, the most surprising thing is that the perpetrator is very rigorous in reverse thinking, and the school can't even lock the suspect for a while. Unexpectedly, three days later, the school announced that the case was solved. The person who solved the case was not the police, but a freshman. A freshman named Qiao Shiyi.

According to Qiao Shiyi's deduction at the time, it turned out that Liu Yong, the deceased, was lazy and lazy. It was because of his parents' nepotism that he entered the police academy without taking the college entrance examination. Feng calling and drinking?

After a long time, I found that apart from Zhang Feng in a dormitory, everyone else was not easy to mess with.Of course, the persimmons should be picked and squeezed softly.And because of character issues, everyone in the dormitory is unwilling to make friends with Liu Yong. That is to say.

Zhang Feng was a child who grew up in bitter water since he was a child. It is nothing to suffer a little. He has always studied well and was admitted to the police academy. Monk Zhanger couldn't figure it out at all. After a long time, he fell to the last few.

And Liu Yong's bullying is undoubtedly adding fuel to the fire.After that incident happened, what Liu Yong did made Zhang Feng feel murderous.

It turned out that Zhang Feng liked a girl in the same class, and he secretly followed that girl home on weekends. Liu Yong found out about this for some reason. Looking at the girl's face, he said how wretched Zhang Feng was and how he had a crush on her.

The girl felt ashamed, so she slapped Zhang Feng and ran away. Zhang Feng wanted to apologize, but Liu Yong stopped him and poured the strong curry sauce from head to toe. At the end, he did not forget to say: "The toad wants to eat swan meat, but you don't look at your own virtue? But... you also know what I want, I'm just a woman, we are buddies, if you want, I'll give it away after playing You! Hahahahaha, no thanks brother!"

Originally, Zhang Feng had never thought of killing Liu Yong before. It was his last sentence that completely angered Zhang Feng. For a while, all the humiliation in the past kept pouring into his heart like a wave. Killing heart.

Because he studied criminal psychology, Zhang Feng endured it for a while, and made a perfect murder plan.

First, on the day he made an appointment for dinner in the dormitory, he deliberately said that he would go to a part-time job, because he knew that Liu Yong would not go, so he made an excuse to stay, and the eleventh holiday began the next day. After returning home, Liu Yong called home in the morning and said he would stay another night.

Zhang Feng was on night shift at an Internet cafe not far from the school, guessing that Liu Yong was going back soon, he excused his stomach ache and left.

He took a taxi back to the dormitory at the fastest speed, climbed into the dormitory on the third floor through the unmonitored back door, hid behind the door, wrapped the steel wire around his hand, deliberately left the sharp end, and when it was clenched into a fist, it was like a fist With a sharp dagger, Liu Yong, who was defenseless, was punched on the temple by Zhang Feng as soon as he came back, and the blow was fatal.

It stands to reason that a homicide of this level should be easily solved, but Zhang Feng's main focus is on criminal psychology, so naturally he won't just let it go.

After corroding Liu Yong's wound with sulfuric acid, he put on gloves and locked the corpse in a closet. He placed the corpse in a kneeling posture, fixed it with Liu Yong's bed curtain rope, and cleaned it with the tools he had prepared in advance. The blood on the ground, and then climbed down from the back door again with the tools, and threw the tools and steel wires into the incinerator and burned them all.

On the way back, Zhang Feng didn’t forget to buy a bunch of late-night snacks at the roadside food stalls. When he returned to the Internet cafe, he told the person on duty that he went out to buy some food after going to the toilet. He was very generous. Treat him to supper.

The next day, Zhang Feng swiped his student card to enter the school from the main entrance, so when the police came to investigate, Zhang Feng said that he was not at school the day Liu Yong died. After the police read the timetable of everyone in the dormitory , and ruled out Zhang Feng without much thought.

Maybe Zhang Feng's acting skills were so good, the police didn't lock down the suspect for several days, but Qiao Shiyi just followed the police to watch the video of everyone in the dormitory making statements, and immediately pointed out that the suspect was Zhang Feng.

The police officer who took the lead was an old police officer, and said a little bit dumbfoundingly: "We were the first to rule out Zhang Feng, why did you insist that Zhang Feng is the murderer?"

Qiao Shiyi sneered, and displayed the videos of Zhang Feng's dormitory recorded statements on the computer screen one by one, then pointed to Zhang Feng's video and said, "Do you see any difference?"

The old policeman watched for a long time, then shook his head to signal Qiao Shiyi to continue.

"Continue to talk about it, what do you find?"

"When everyone was interrogated, they all looked nervous, either rubbing their hands, or their eyes were slack, but Zhang Feng, his eyes were firm, and his expression was calm, as if everything was under his control. Although he looked thin and weak As far as I know, Liu Yong has severely humiliated Zhang Feng more than once before his death, so Zhang Feng is more serious than others. There is a motive to kill!"

Qiao Shiyi spoke clearly, but the young policeman next to the old policeman said, "But he has an alibi for that day, and someone can testify!"

"Then you go ask the witness, did Zhang Feng never leave the Internet cafe halfway?" Facing doubts, Qiao Shiyi did not waver at all, and still insisted on her own ideas.

The old policeman signaled the people behind him to stop talking, and then he really called a witness and asked Zhang Feng if he had left the Internet cafe. The witness thought about it and said that he had gone out to use the toilet and bought a midnight snack.

For a moment, the suspect was immediately locked in. The old policeman gave Qiao Shiyi an appreciative glance, and then immediately applied for Zhang Feng's arrest warrant. Within three days, Zhang Feng explained everything, and Qiao Shiyi was also in the police academy, and even the police circled out. name.

Afterwards, when the veteran policeman asked Qiao Shiyi why he was so sure, Qiao Shiyi just smiled and said three words: "I guessed it!"
