Card Room - 24. Chapter 028-029

[Chapter 28, Scarlet Maple Leaf 7-New Discovery]

3 Secret Chamber of Hearts, the next day.

When Xiao Lou woke up, Yu Hanjiang was standing by the corridor window, with deep eyes staring into the distance, frowning, as if thinking about something.

Xiao Lou walked over and asked, “Team Yu, are there any new discoveries?”

Yu Hanjiang pointed to the maple forest and said, “There was a violent storm last night, and several maple trees over there were blown down.”

Xiao Lou followed his gaze and saw that in the maple forest in the distance, a large number of maple leaves were falling under the washing of rain, and the ground seemed to be covered with a thick red carpet of maple leaves. At the end of the maple grove, a few young saplings that had not been planted were blown to the ground by the wind. The flowerbeds downstairs in the teaching floor were swaying, and many flowerpots were broken. The whole campus was in a mess, like a typhoon.

At half past six in the morning, the rain had stopped.

At this time, the two of them should have gone to guard at the gate of the school. There will be new clues in the new day. However, they sneaked into the Shuxianglou to investigate and alarmed the security guards. The door of the Shuxianglou was locked by the security guards.

Xiao Lou slept very uncomfortably last night. He rubbed his temples with a headache and said, “Class is coming soon, how are we going out?”

Yu Hanjiang looked calm and pointed at the air-conditioning duct outside the window: “Climb out.”

Xiao Lou: “…”

In the secret room of hearts, Yu Hanjiang took the attitude of clearing the secret room of spades. He simply opened the window and jumped, grasping the air-conditioning duct accurately with both hands, while stepping on the edge of the window that was only 10cm wide with his feet, crawling down layer by layer.

Xiao Lou’s heart touched his throat.

So high, if he stomped on the air with one foot, it would be over if he fell down!

But the facts proved that Xiao Lou’s worries were superfluous. Yu Hanjiang seemed to do things like climbing and jumping frequently. Men were familiar with all kinds of buildings and quickly chose the most convenient path and landed steadily on the ground. Go up, look up at Xiao Lou.

Xiao Lou poked his head out and looked down. Of course he didn’t dare to climb down from the fifth floor by stepping on the window edge… He didn’t want to fall into a half body.

Yu Hanjiang gave him a gesture of “Go downstairs and wait for me”, and quickly walked to the door of the Shuxiang Building.

Team Yu didn’t know where to find a wire, and after a moment of tossing, the door was unlocked. Xiao Lou was waiting at the door. Seeing the Yu team opened the door, he couldn’t help thinking—thanks to Yu Hanjiang being a policeman, if he were to become a flying robber, no one would be able to stop him, right?

Yu Hanjiang seemed to see Xiao Lou’s doubts, and while restoring the door lock, he explained: “When I was in the police academy, a senior taught me how to unlock the lock. He liked to study these gadgets.”

Xiao Lou nodded, did not ask much, and turned around to the school gate with Yu Hanjiang.

From seven o’clock, some students came to the school one after another.

Xie Xinghe came very early today, and it is strange that a black veil was tied to the outside of his school uniform—black veil meant to commemorate the dead. The person he was commemorating was obviously Ying Xiaoya, who fell to his death yesterday.

Xiao Lou couldn’t help being confused when he saw this. Judging from Xie Xinghe’s confession, his relationship with Ying Xiaoya is very ordinary. But he wore a black gauze today, at least it shows that he is very concerned about Xiaoya’s death.

Before long, Yi Ru and Yu Hui also came, also wearing black gauze on their arms.

The three met at the school gate, and they were stunned.

Yu Hui frowned and took a step forward, glanced at Xie Xinghe’s arm, and said, “Xie Xinghe, what are you doing with this? Our Xiaoya doesn’t need you to pay memorial service!”

Xie Xinghe said blankly: “I know your hostility towards me is difficult to dissolve. However, I have been with classmate Xiaoya for three years, and her death…I am also very sad.”

What else did Yu Hui want to say, Yi Ru said: “Don’t be arguing, do you want to be onlookers at the school gate?”

Yesterday, Yi Ru had a emotional breakdown and cried for a long time in front of the police. After a whole night of adjustments, she has returned to normal. However, there are thick dark circles under her eyelids, her expression is exhausted, and she obviously did not rest well.

Yu Hui walked forward with a cold face.

The three people entered the Chongwen Building in the third grade one after another, and were silent on the road.

The other students should have nothing to do with the case, and the content of the discussion did not contain any valuable information. Xiao Lou and Yu Hanjiang still couldn’t recognize the faces of thousands of students, but they did not leave the school gate.

They are waiting for the chemistry teacher in the third grade (3) class to show up.

At 7:25, with 5 minutes left before the morning reading class, a tall female teacher walked into the school gate quickly.

She has a capable and short hair, wearing black pencil pants and a white shirt, matching a long khaki windbreaker, stepping on high heels, walking gracefully, as if she has learned professional dance, slender and straight body. Zi looks very temperamental.

The security guard greeted her: “Ms. Qin, have you come to work?”

The female teacher smiled and nodded to the security guard, and walked quickly to know the building.

Xiao Lou and Yu Hanjiang immediately became alert.

Teacher Qin, the security guard greeted her specifically, seeming to remind the challenger that this is the chemistry teacher from Class 3 who asked for leave yesterday.

Xiao Lou and Yu Hanjiang looked at each other and quickly followed her.

She went directly to the chemistry office on the third floor of Xingzhi Building. As soon as she walked into the office, a colleague said to her, “Weiwei, you are really lucky. You took a leave of work yesterday, don’t you know? There’s one in class 3. The student committed suicide by jumping off the building!”

Qin Wei was stunned for a moment, then suddenly turned around, “What? Who jumped off the building?”

A colleague said: “In this monthly exam, Ying Xiaoya is the last one in the whole grade.”

The expression on Qin Weiwei’s face was full of shock: “How could it happen? I remember that the girl studied very seriously. I didn’t do well in the exam this time. It was just an accident. I still want to encourage her. If I didn’t take the exam once, there is no need to commit suicide by jumping off the building. ?”

Xiao Lou and Yu Hanjiang pretended to be passing teachers and saw the situation in the office clearly.

Qin Weiwei, a chemistry teacher, either has a deep mind and first-rate acting skills, or is really innocent. He doesn’t know what happened to Ying Xiaoya who jumped off the building. There is no conclusion yet. The police will definitely come to investigate today. she.

Today’s morning reading class for class 3 is a Chinese class, and the head teacher asked everyone to recite the text for half an hour.

The first class at 8:10 happened to be the chemistry class. Qin Weiwei prepared the textbooks and walked out of the office to the third grade (3) direction. Yu Hanjiang and Xiao Lou came out of the bathroom opposite the office and looked at her back. Yu Hanjiang said in a low voice, “You follow Qin Weiwei. I’ll go to the school gate and wait for the police. I’ll come back to you later.”

Xiao Lou nodded and followed Qin Weiwei quietly.

During class time, there were many teachers coming and going in the air corridor, and she didn’t notice Xiaolou behind her.

Qin Weiwei walked into the classroom with the textbook-I don’t know if it was because she did not experience the accident that Ying Xiaoya fell from yesterday, or because her mental quality was really too strong. Absent-minded, she also did her job as a teacher and finished the class.

Xiao Lou is also a teacher. From the perspective of peers, this teacher Qin is of first-rate class, her chalk writing is correct and timeless, she never talks nonsense in class, and prepares the lessons well-45 minutes of class, clearly organized , The priority is clear, the key knowledge is explained clearly, and it can be almost directly used as a demonstration class.

Xiao Lou couldn’t help but stroked his chin…Is such a teacher really a cruel murderer?

***

At this time, Yu Hanjiang was standing behind a tree and staring in the direction of the school gate.

The police really came!

The four police officers who came today are the same as yesterday. Obviously, after the forensic doctor took the body back yesterday, after an autopsy, he confirmed the cause of death, and told the criminal police all the information he knew—these policemen came with a lot of clues.

They first found the principal, and vacated an office in Xingzhi Building. They immediately called the physical education teacher from Class 3 and the security guard on duty yesterday to ask.

The office door was about to close, and Yu Hanjiang immediately put on an invisibility cloak and went in to listen.

The police drove the recorder and asked the physical education teacher while recording: “Who was the person who called you when Ying Xiaoya had an accident yesterday in physical education class?”

The physical education teacher was taken aback, and quickly replied: “It’s Teacher Qin. Didn’t she change classes with me? I called and cared about the students’ situation. I asked her where she was, and she said she was going to take her father to the hospital. Check it out.”

“Are you familiar with Teacher Qin? Did you meet her yesterday?”

“We are very familiar. We were assigned to this school together five years ago, and we have been taking the same class. She would change classes with me when something happened.” The physical education teacher paused and said, “She asked for leave yesterday. I haven’t seen her.”

“What kind of person do you think she is?”

“Very cautious, attentive, and beautiful. Teacher Qin is very popular in school.”

The police called the security guard over and asked some questions: “Have you seen Teacher Qin yesterday?”

The security guard looked puzzled: “I haven’t seen it. Didn’t she ask for leave? I saw her come to work this morning.”

“You are keeping the key on the roof of Xingzhi Building, right? Have you ever loaned it to others?”

“No…” The security suddenly thought of something and straightened up and said: “However, I accidentally lost a whole bunch of keys while patrolling the school last month. Teacher Qin returned them to me after they picked them up.”

The two policemen looked at each other: “Are you sure it is Teacher Qin?”

Security: “Of course, after she returned it to me, I also invited her to have a meal in order to express my gratitude!”

After the persons involved in the case walked out the door, the two policemen began to discuss in low voices.

The captain said: “This teacher Qin has a big problem. I brought the surveillance data back yesterday. She happened to come to the school when the deceased’s accident happened to prove that she was lying. She picked up the key and returned it to the security guard. Moreover, the deceased The poison is organophosphate. She bought a bottle of organophosphate when she was shopping for medicine last week.”

The female police officer said: “The poison in the dead was found in Yu Hui’s chocolate, and Yu Hui is also very suspicious.”

The captain said: “Yu Hui should be fine. The chocolate is likely to be dropped. Call them to come over for a trial later.”

At this moment, a policeman came in with the door opening, holding half a bottle of organic phosphorus in his hand, and a signature book.

The young detective said, “Boss, I found the poison in the chemical laboratory.”

The captain took a look and said, “You two, go to the third grade (3) class immediately to guard, and after class, you will call all the three suspects Qin Weiwei, Yu Hui, and Xie Xinghe over!”

The time for Yu Hanjiang’s cloak was almost up, so he had to leave the office and quickly return to Class 3 of Senior High.

Xiao Lou was eavesdropping at the back of the classroom. Yu Hanjiang walked over and whispered in his ear: “The police have arrived. The suspect will be interrogated after class. Go ahead and make preparations. Follow them to listen to the interrogation. I will cover you outside. .”

Xiao Lou nodded, and returned to Xingzhi Lou with Team Yu.

The two hid in the bathroom, and Yu Hanjiang simply repeated what he had just heard to Xiao Lou. After the suspect arrived, Xiao Lou immediately put on an invisibility cloak in the bathroom and followed the suspect into the interrogation room.

The first person to be interrogated was Yu Hui.

Yu Hui frowned and looked at the police officer: “Police officer, didn’t you ask me yesterday? What else do you want to ask?”

Policeman: “Your box of sandwich chocolates is full of organophosphorus poisons. How do you explain it?”

Yu Hui was horrified: “What?!”

He was stunned for a long time, and finally realized what the police meant: “Don’t you think that I want to poison Xiaoya?! Fuck! What a joke, I treat her as my sister! This chocolate must have been dropped!”

Police: “Since you are brothers and sisters, why don’t you make your relationship public so that people will misunderstand that you are in love?”

Yu Hui irritably scratched his hair and said: “I am the same age as her, only three days older than her. This girl has never called me brother since she was young. It is embarrassing to let the classmates know that we are brothers and sisters when two people are in the same class. Okay? So at school, we both call each other names. I didn’t expect to be misunderstood!”

The policeman asked: “Did she live in your house since she was a child? How is your relationship?”

Yu Hui said: “When she was seven years old, her parents divorced. Her parents were away from home. They didn’t care much about her. They took care of her in our house. We grew up together, and our relationship is closer than our brothers and sisters.”

He paused, and then said: “So Xiaoya’s suicide note must not have been written by her! I’m sorry mom and dad, such parents are sorry for the ass! She really wants to commit suicide, the most sorry is that it should be my parents!”

The police then asked: “Have anyone touched your chocolate?”

Yu Hui: “I don’t know. The box of chocolates was bought at the supermarket last week. I have kept it in my school bag for a week.”

Police: “Have you eaten for Ying Xiaoya?”

Yu Hui thought about it carefully: “When I ran yesterday, I did give her a chocolate.”

Police: “Why was she late yesterday?”

Yu Hui: “Her mother suddenly came back to see her and bought her a mobile phone as a birthday present for her 18th birthday. She was very happy. She went back to stay at the hotel with her mother at night. We did not return to my house. We used to go to school together. Xiaoya wakes up very early every day, and it’s strange that she is late!”

The police told Yu Hui to go back. He had no motive for murder and had not been exposed to poison, so even though the chocolate came from his hands, his suspicion was the least.

Even more suspicious were Xie Xinghe, who checked the signature of the medicine in the laboratory class, and the chemistry teacher who bought the medicine directly.

******

[Chapter 29, Scarlet Maple Leaf 8-Suspect’s Testimony]

Xie Xinghe was soon taken into the interrogation room.

The police asked directly: “In the chemical experiment class last Wednesday afternoon, your class was in laboratory 3, right?”

Xie Xinghe: “Yes.”

Policeman: “Did the experiment class talk about organophosphorus? The chemistry teacher gave you a bottle of medicine as a demonstration?”

Xie Xinghe looked calm: “Yes.”

Police: “In the end, you checked the medicine and put it back in the cabinet?”

Xie Xinghe was silent for a moment, and said: “I am the monitor. It is my duty to check the equipment and reagents after the experiment.”

Police: “Half a bottle of medicine is missing. Did you take it?”

Xie Xinghe frowned: “No, the bottle was full when I checked.”

The police looked at each other and found that Xie Xinghe’s expression was calm, not like a lie, and his testimony was indeed flawless, so he went back first and called in the chemistry teacher.

Qin Weiwei, who is currently the most suspicious, walked into the interrogation room with a dazed face.

She sat down and said in a puzzled way: “Police officer, what do you want to know?”

The police said: “Did you not ask for leave yesterday? However, we went back and checked the surveillance all day. The surveillance records at the school gate showed that you went back to the school around 11:20 and left at around 11:40.”

Xiao Lou was slightly startled when he heard this, and immediately cheered up.

Qin Weiwei explained: “I asked for leave to take my dad to the hospital, and found that my dad’s medical insurance card was forgotten at school, so I took a taxi back to get it.”

Police: “In other words, during the time Ying Xiaoya committed suicide by jumping from a building, you were actually at school.”

Qin Weiwei’s face changed, and said, “Don’t you doubt me?!”

The police looked serious: “Please answer the questions and cooperate with the investigation.”

Qin Wei took a deep breath and said, “During this time, I was indeed in school. I even called the physical education teacher to ask about the students’ situation. He said that he was organizing students to play basketball. I didn’t know that Ying Xiaoya jumped off the building. I took the medical insurance card and left.”

Police: “Last month, the security key was lost. Did you pick it up and return it to him?”

Qin nodded slightly: “That’s right.”

Policeman: “So, it is entirely possible for you to have a key on the roof?”

Qin Weiwei’s face was extremely ugly: “What do you mean? What do I do with the key on the roof? After I picked up the key, I was in a hurry to go to class, so I put it in the office and returned it to the security guard after the class. Maybe someone took the key during this period!”

Policeman: “Did you buy this bottle of organic phosphorus?”

Qin Weiwei: “Yes, I told the students about organophosphorus and inorganic phosphorus, and I bought a bottle so that they could recognize this poison so as not to accidentally come into contact with it. I also taught them the first aid knowledge of organophosphorus poisoning. …Wait, why do you suddenly ask this?”

Police: “Organic phosphorus was found in the blood of the deceased. She was poisoned before falling down the building. Half of the medicine in the chemical laboratory was taken away. Xie Xinghe said that when he checked, the medicine was still full, so he can go to the laboratory casually. You are the only one who took the potion.”

Qin Weiwei’s face turned pale: “I didn’t take it!”

Police: “Ms. Qin Weiwei, you are suspected of killing Ying Xiaoya. This is an arrest warrant.”

Qin Weiwei couldn’t believe it, “Police officer, you are mistaken! I really didn’t take any medicine, nor did I have a key. I went back to school just to get my dad’s medical insurance card. My dad can give it to me. testify……”

Police: “Please go back to the police station for investigation.”

Before she could finish speaking, a cold handcuff was put on her hand.

The police took the arrest warrant and took Qin Weiwei away as a suspect.

Xiao Lou hurried out after the police.

Yu Hanjiang pretended to be passing by and walked into the bathroom. Xiao Lou also entered the bathroom wearing an invisibility cloak.

Xiao Lou said in Yu Hanjiang’s ear: “Qin Weiwei is too suspicious. She found the key to the security. At the time of the incident, she went back to school and called the physical education teacher… and happened to have bought an organophosphorus poison.”

At this time, the effect of Xiao Lou’s invisibility cloak had not ended, so Yu Hanjiang could only hear him speaking, but couldn’t see where he was.

However, Team Yu was very calm and still had a calm expression when talking to the air: “So, the police will bring her back for investigation?”

At this time, Xiao Lou’s cloak lost its effect, and he appeared beside Yu Hanjiang out of thin air.

Yu Hanjiang glanced at him and said, “What do you think of Professor Xiao?”

Xiao Lou frowned: “I don’t think it’s right.”

At this moment, a prompt popped up in the floating box of the two at the same time——

[Result of the secret room of Hearts 3: The murderer was Qin Weiwei, a chemistry teacher? whether. 】

[Note: If the reasoning is wrong, the challenge will fail, and you will be sent to the nightmare room to be punished. 】

The two looked at each other and pressed “No” at the same time.

They said in unison: “Qin Weiwei is not a murderer.”

Yu Hanjiang looked at Xiao Lou appreciatively and said, “How did you analyze it?”

Xiao Lou sorted out his thoughts and said: “First, Teacher Qin has the key to the chemistry laboratory. If she wants to take away the organophosphorus poison, she doesn’t need to pick the lock. But when we checked the laboratory last night, we found that the door lock was locked. The traces of the prying; Second, she is a chemistry teacher. If she really wants to poison Ying Xiaoya, there are so many methods. There is no need to take the poison from the chemistry laboratory and leave such a big handle.”

He paused, and then said: “According to the forensic test, Ying Xiaoya was poisoned, and the source of the poison was the chocolate that Yu Hui gave her. However, the poison that can be contained in the sandwich chocolate is very limited, and this amount of organic Phosphorus is not deadly. Unless Ying Xiaoya is so hungry that she eats up a whole box of chocolates-but Yu Hui has a lot of chocolates left in her schoolbag, which means Ying Xiaoya should only eat one or two.”

A careful review of Yi Ru’s confession yesterday, during the physical education class, the boys were playing ball, and the two returned to the teaching building. Ying Xiaoya said she was hungry and asked Yi Ru to buy food. During Yi Ru went to the canteen to buy potato chips, Ying Xiaoya might be too hungry, so she ate a piece of chocolate.

When running exercises in the Chinese class, Yu Hui once stuffed Ying Xiaoya a chocolate, and Ying Xiaoya put it in her pocket.

Xiao Lou just noticed this scene at the time-Yu Huisai gave her a ball-shaped chocolate with a diameter of about 3cm, wrapped with golden sugar paper, and Ying Xiaoya should have eaten this one.

The poison content of a sandwich chocolate is very low and will not cause direct death of the user. However, acute organophosphorus poisoning will still cause miotic and muscle tremor reactions. As long as the rescue is in time, it will be fine.

After eating chocolate, she went to the rooftop and fell to her death.

Xiao Lou finally said with certainty: “The real cause of her death is still the skull fracture and cerebral hemorrhage caused by falling from the building. The dose of chocolate poisoning is not fatal.”

After Xiao Lou’s professional analysis of the toxicant dose, Yu Hanjiang was more convinced of his inference.

He whispered: “Yu Hui’s chocolate has been manipulated. On the surface, it seems that Qin Weiwei has enough time to commit the crime, and all the suspicions are directed at her… However, the police overlooked one key point.”

Yu Hanjiang looked at Xiao Lou and asked the other person a question: “If you want to kill a person, after poisoning the other person, will you push the other person downstairs again?”

Xiao Lou’s eyes lit up suddenly.

——Yes, poisoning and falling from a building are all methods that can kill people. There is no need to use them twice!

——This is simply “superfluous”.

If the murderer wants to poison Ying Xiaoya, first of all, he shouldn’t use “sandwich chocolate” food with a very small amount of poison, and put it in Yu Hui’s chocolate…what if it is eaten by Yu Hui? Isn’t the poison wrong with Yu Hui? A better method is to directly poison Ying Xiaoya’s diet without knowing it.

And if the murderer wants to push Ying Xiaoya down from the top of the building and fall to her death, copying her suicide note, creating the illusion that Ying Xiaoya commits suicide, there is no need to do so, and instead let the police detect the poison from Ying Xiaoya’s body.

Xiao Lou felt his chin and thought for a moment, and said, “Could it be that two people committed the crime? But the two contradicted each other, so they left a loophole?”

Yu Hanjiang’s eyes were deep: “Yes.”

This is what Yu Hanjiang finally thought about after carefully sorting out all the clues for the past two days and the testimony of all the suspects.

——Ying Xiaoya’s case can actually be decomposed.

The first part is a case of poisoning.

The other party does not necessarily want to poison Ying Xiaoya, because the method of poisoning is through Yu Hui’s chocolate. The poisoner knows that Yu Hui often gives Ying Xiaoya chocolate, so if the sandwich chocolate is dropped, there is a 50% probability of poisoning. To Yu Hui, there is a 50% probability that Ying Xiaoya is poisoned. It is still impossible to confirm who this poisoned person is and what his purpose is.

But what can be confirmed is that his method of poisoning does not want to kill Ying Xiaoya directly.

No one will eat dozens of chocolates in one go. Half a bottle of organic phosphorus is dispersed in dozens of chocolates. The toxin content of each can’t be poisoned to death, but it is enough to attract people’s attention—perhaps the poisoner is passing through. What does this approach remind me.

Excluding Yu Hui, he loves chocolate and has no motive to poison his sister. Both Yi Ru and Xie Xinghe were suspected. The door lock of the laboratory had been smashed. All the teachers who knew that Yu Hui often gave Ying Xiaoya chocolate were also suspected.

The second part of the case is the case of falling from a building.

Yu Hanjiang inspected the scene on the roof of the building yesterday, and the footprints on the roof were disordered. It is very likely that there was a second person on the scene. This person pushed Ying Xiaoya downstairs, which directly led to Ying Xiaoya’s death. In addition, this person cleverly copied the handwriting and forged a “suicide note” for Ying Xiaoya, creating the illusion of “suicide” for Ying Xiaoya.

This person is the one who really wants Ying Xiaoya to die!

Unfortunately, he/she did not know that Ying Xiaoya had been poisoned before falling down the building.

The police took the body back and found that Ying Xiaoya was poisoned. In this way, the police would quickly rule out the possibility of Ying Xiaoya committing suicide-the murderer’s forged Ying Xiaoya’s suicide note turned out to be the biggest failure.

Forensic medicine detected the source of the poison, and the police locked chocolate, organic phosphorus, and laboratories. All suspicions were directed at chemistry teacher Qin Weiwei.

Although Teacher Qin was taken away for investigation, the police will soon conclude that she is not the murderer.

Because it doesn’t make sense.

No one is stupid enough to throw a small amount of toxins first, then push people off the roof and forge suicide notes.

The case will be split soon.

One person dropped the toxin-containing sandwich chocolate, and the other pushed Ying Xiaoya off the roof. Because the two people did not know each other’s actions, they caused a huge oolong.

Yu Hanjiang glanced at Xiao Lou and said: “Last night there was a heavy rain and the school was so messy. Today, the school will definitely be cleaned on a large scale. The murderer may destroy the evidence. We must precede the murderer.”

Xiao Lou was also nervous: “Where does Team Yu want to search?”

Yu Hanjiang: “The biggest trash can in the corner of the school.”

***

The teaching building and office building of Fenglin High School are equipped with small trash cans. The garbage that students clean up every day will be collected in these small trash cans, and then the garbage will be collected by the cleaners in the trash cans behind the playground.

This trash can should be cleaned every two to three days, and a professional garbage disposal truck will come over to pull all the contents away.

Last night, due to violent storms and rain, the campus was in a mess. In the morning, after cleaning the playground, the cleaners collected a lot of leaves, broken branches, broken flower pots and other trash into the trash can. This trash can is full. It must be called trash. The car comes to clean up.

When Yu Hanjiang and Xiaolou came near the trash can, the cleaning workers happened to pick up the trash outside.

Xiao Lou walked forward quickly and said to the cleaner: “Auntie, I’m sorry, I’m a teacher in the first grade. I accidentally thrown important documents into the trash can yesterday. Can I find it here?”

Aunt Cleaning said: “Oh, what credentials? It’s too dirty here, please don’t touch it, teacher, let’s find it for you.”

Xiao Lou said nervously: “It’s my teacher qualification certificate. When I lost the waste paper yesterday, I threw it away without seeing it clearly. Could you please help me find it, I’ll wait here, thank you.”

Yu Hanjiang: “…”

Professor Xiao’s acting skills are very good.

With this reason, the two can stand upright beside the trash can and observe.

The aunt cleaner turned the trash out while helping them find the certificate, still muttering: “After you throw out the trash, you need to check it. You said, such an important certificate, what if you can’t find it.”

Xiao Lou nodded: “I was too negligent.”

At this moment, Yu Hanjiang’s eyes suddenly narrowed: “Wait.”

The cleaner was stunned: “What’s the matter with the teacher?”

Yu Hanjiang walked over, not too dirty, and picked up a pair of shoes from a pile of waste paper and messy leaves.

It is a pair of ladies canvas shoes, size 37, which is the same as Ying Xiaoya’s shoes.

Seeing this, the cleaner couldn’t help saying: “Who lost the shoes? These shoes look quite new!”

Yu Hanjiang and Xiao Lou looked at each other.

Important evidence was found.

Ying Xiaoya’s footprints left on the rooftop are so messy because there are two people’s footprints—the other is wearing the same shoes as hers. And the fragments of her scarf were left on the roof, it must have been the conflict between the two before she was pushed down.

The murderer threw the unfit shoes into the trash can, because the murderer knew that the school’s trash cans would be cleared today.

As long as the garbage truck takes the garbage away, it is dead and unjustified.

Unfortunately, Yu Hanjiang and Xiao Lou found these shoes.

Prove that their inference just now is correct.

In Ying Xiaoya’s case, two murderers were acting at the same time!

Many little angels in the comment area are analyzing and discussing. Everyone is very serious. It is the first time to write a reasoning subject and be recognized. I am super happy.

The truth is about to emerge:)
