"Why does Mr. Wen have time to come to the police station today?" In a nearby café, Wen Yifan and Liu Wenyu chose a two-seater, ordered two drinks at random and asked

"It's just that I've become a little interested in the recent case," Wen Yifan said with a smile, "Can you tell me about the details of the case?" ”

"This ...... It may be more difficult," Liu Wenyu frowned, "After all, Brother Wen, you also know that this case has a great impact, and the people above the adjudication court have issued a death order to solve the case quickly, and it must be kept secret from the outside world, which may be ......"

"I see, then I won't be reluctant," Wen Yifan smiled, "Then can you tell me some details of the problem?" ”

"Details?" Liu Wenyu was puzzled, "What kind of details does Brother Wen want to know?" ”

"For example, the precise time of the crime," Wen Yifan took a sip of chilled milk, the slightly viscous taste with the cold feeling made him smile a little, "The time of the crime and whether the case was a premeditated murder or a murder of passion?" ”

"The time of the crime is 3:37 p.m., and there are no eyewitnesses," Liu Wenyu took a sip of coffee, "You still like this thing so much." ”

"It's just a habit," Wen Yifan chuckled, "was it premeditated, or was it murder in passion?" ”

"Now most people think it was a premeditated murder," Mr. Liu said, "including me." ”

"Oh? Why? Wen Yifan looked at him suspiciously.

"The suspect in the case, Liu, arrived at the school at three o'clock in the afternoon of the same day, and then stayed near the school for a period of time, during which he bought three bottles of beer at the nearby commissary with the money from selling garbage, and sat in an inaccessible open space near the school to drink them all, and was suspected of having a verbal altercation with a Luo sex woman, and the investigation later revealed that the woman was the parent of a student at the school, and the child who came here to listen to the psychology lecture, the quarrel occurred because Liu flattered him and made him feel disgusted, then kicked over Liu's beer, and the two clashed. Liu Wenyu said, "Then at half past three in the afternoon, the victim and his classmates passed by the open space where Liu was, and were abducted by Liu into a green belt and brutally raped and killed. ”

"Interesting," Wen Yifan took another sip of rice milk and asked, "Tell me why you judged it to be premeditated murder." ”

"It's very simple, according to the memories of the security guard who knew Liu, Liu often recycled garbage at school, but it was the summer vacation of students, and it stands to reason that the school had no garbage to collect, why would Liu return to school at this time?" After a slight pause, he continued, "Also, after being arrested, some Wan Ai Ke ingredients were found in Liu's body, which proves that the suspect took drugs before the incident, and proves that this is a premeditated murder. ”

"It's getting more and more interesting," a glimmer of light flashed in Wen Yifan's eyes, "So how did Liu explain the first point you said?" ”

"He quibbled, saying that the school doorman called him before and asked him to come and collect garbage," Liu Wenyu smiled, "but the doorman didn't call him at all, and we checked the doorman's call records afterwards, and found that the doorman only called him once in mid-May, and didn't even mark any contact information, and the doorman didn't call him at all after that, which is a pure lie." ”

"So have you checked Liu's call records?" Wen Yifan asked suddenly.

"Liu's call logs?" Liu Wenyu was puzzled, "It's really not, why are you checking this?" ”

"It's nothing, keep this detail for now," Wen Yifan smiled back, "As you said, students have already been on vacation after July, so why do students still come to school?" ”

"Isn't there a lecture by a psychology expert?" Liu Wenyu smiled, "But I feel that if you want to talk about psychology, Brother Wen, you are amazing!" ”

"Psychology lectures, it stands to reason that only students know, so why can he, a waste picker, know these things?" Wen Yifan threw out questions.

"So it's a premeditated murder," Liu Wenyu waved his hand, "Now we all agree that Liu has been targeting the victim for a long time, which the students have heard about for a long time, and the homeless man who collects garbage is a pervert, and he did talk about this psychology lecture in a conversation with the students, which the students concerned can confirm." ”

"It's more interesting," Wen Yifan smiled, took out a piece of paper from his bag, and handed it to Officer Liu, "Look at it, is this a leaflet for psychology lectures given to students by the school?" ”

"Yes, this is it," Liu Wenyu wondered, "where did you get it?" ”

"The leaflet is too easy to get, many students throw it directly into the trash, if Liu is a waste picker, then he must be able to get it, maybe this is also evidence that can prove that he is premeditated murder," Wen Yifan said leisurely, "But have you taken a closer look at this leaflet?" ”

"Careful?" Liu Wenyu smiled, "Of course, we carefully compared the time and came to the conclusion that this is indeed in line with the time of the crime, what's wrong?" ”

"Don't limit your gaze to a certain place," Wen Yifan stretched out his finger and tapped the flyer, "Look at this sentence." ”

"Interested students are invited to arrive at the school podium at one p.m. on July 19 to listen to the presentation." Liu Wenyu read slowly, "What's wrong with this? ”

"Please interested students," Wen Yifan added the word "interest", "what does this sentence represent?" ”

"Interested?" Liu Wenyu asked, "What does it represent?" ”

"It means that this lecture is not mandatory for students to attend." Wen Yifan smiled, "This is a lecture that is just recommended for students to listen to. ”

"Ah, what do you mean......" Liu Wenyu showed a look of sudden realization.

"Yes, for a non-mandatory lecture, how many students are willing to sacrifice their summer vacation time to come here to listen to a lecture? If they are interested in psychology, they should study it entirely at home, after all, the Internet is so developed. Wen Yifan's voice calmed down. In the same way, if I were Liu, even if I knew about the existence of this lecture, I didn't know if the student I was eyeing would come to school, how could I be sure? ”

"Maybe he's just here to try his luck?" Liu Wenyu tentatively probed.

"That doesn't make sense, Liu's emergency is not good, you and I know the price of Wan Aike, it is by no means what people like him use every day, as a scavenger who has eaten the last meal but not the next meal, how can I spend a lot of money to buy medicine, just to try my luck?" Wen Yifan asked, "Therefore, just looking at this, it can be seen that Liu bought Wan Aike when he was sure that she would definitely come." ”

"Then the question is, how is he sure that Luo will come to the school to listen to the lecture?"

"Perhaps...... It was he who ...... after seeing Luo enter the school," Officer Liu pondered, "No, he only came at three o'clock, and the time is not right." ”

"Continue to keep this doubt," Wen Yifan interrupted Liu Wenyu's dead end, "You also said that the vacant land, including the green belt, is inaccessible and nearly a kilometer away from the school, why did Luo and that classmate go to such a place, as far as I know, the bus stop that Luo often goes to is not there." ”

"Listening to the testimony of the classmate who called the police in the lecture, Luo had a class reunion to participate in in the afternoon, so he went to the classmate's home with the classmate to pick up things with her, and then went to the party together," Liu Wenyu frowned slightly, "This is very common among college students." ”

"Common is common, but don't you think that these suspicious points, which seem extremely small, are no longer small when they are connected?" After drinking the last sip of rice milk, Wen Yifan licked his lips and said: "There is a psychology lecture in school, Liu happened to learn about this lecture when he was recycling garbage or chatting with his classmates, and then the victim Luo, who had already been targeted by Liu, happened to listen to this non-mandatory speech, and Liu happened to determine this, so he waited for the rabbit in a place that was inaccessible and suitable for crime, and then ......"

"Luo happened to pass by there for some common reason." Another smile, Wen Yifan licked his teeth, "Don't you feel that this is all like being firmly controlled by someone?" ”

"......" Liu Wenyu no longer spoke, but frowned, and then immediately made a phone call.

"Please check the call records of the suspect Liu immediately!"

After almost shouting and saying this, Liu Wenyu hung up the phone and looked at Wen Yifan.

"Thank you so much, Mr. Wen, I didn't expect such a simple case to hide so many flaws in it," Liu Wenyu said heartily, "If it is really according to what Mr. Wen said, all this does involve a darker existence, and the person who controls all this is so delicate that it is terrifying!" ”

"No matter how fine the layout is, as long as it is artificial, it will eventually leave flaws." Wen Yifan just smiled politely, "More details, including the packaging of Wan Aike that you have not found, are the key to breaking the game, and sometimes, the details really determine success or failure." ”

"I've been taught, I'm really curious why you don't come to be a criminal investigation expert," Liu Wenyu nodded in agreement, "One day when this case is really solved, I will invite you to dinner!" ”

"I don't need to eat, I'm more concerned about the truth." Wen Yifan smiled and nodded.

"Then I'll check first, and I'll give you the truth when the time comes!" Liu Wenyu bowed slightly, and returned to the adjudication court in a hurry.

"......" looked at Liu Wenyu's distant figure, and Wen Yifan was silent.

"It's really energetic," Wen Yifan smiled and shook his head, "It aroused my curiosity, what is the truth?" ”

I got up and straightened my clothes, put the flyer away, and got up to leave.

"Hello, sir, you spent a total of 43.5 yuan on this drink, what do you pay for?" A polite voice came from behind him.

"I vaguely remember that Liu Wenyu seems to have said that he invited me," muttered in a low voice, Wen Yifan showed an embarrassed but polite smile, "Pay in cash, thank you." ”
