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

Room of Hearts 3, Day 2.

When Xiao Lou woke up, Yu Hanjiang was standing by the corridor window, his deep eyes staring into the distance, his brows slightly frowned, as if he was thinking about something.

Xiao Lou walked over and asked, "Team Yu, do you have any new discoveries?"

Yu Hanjiang pointed to the maple forest and said, "It was a storm last night, and a few 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 fell under the scouring of the rain, and the ground seemed to be covered with a thick red carpet of maple leaves. At the end of the maple forest, a few young saplings that were planted not long ago were blown to the ground by the wind. The flower beds downstairs were crooked, many flower pots were broken, and the whole campus was messy, like a typhoon passing through.

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

At this time, the two should have gone to the school gate to stand guard. There will definitely be new clues in the new day. However, last night they sneaked into the scholarly building to investigate and alerted the security guard. The door of the scholarly building was locked by the security guard.

Xiao Lou slept very uncomfortable last night. He rubbed his temples with a headache and said, "It's almost time for class, how do we get out?"

Yu Hanjiang looked calm, and pointed to the air-conditioning pipe outside the window: "Climb out."

Xiao Lou: "..."

In the secret room of hearts, Yu Hanjiang showed the attitude of clearing the secret room of spades survival. He simply opened the window, jumped up, grabbed the air-conditioning duct with both hands, and stepped on the edge of the window, which was only 10cm wide, and climbed down layer by layer.

Xiao Lou's heart was raised in his throat.

So high, if he steps in the air with one foot, he will fall!

But it turns out that Xiao Lou's worries are unnecessary. Yu Hanjiang seems to do this kind of thing often - climbing, jumping, the man is familiar with all kinds of buildings, he quickly chooses the most convenient path and falls firmly on the ground up, looked up at Xiao Lou.

Xiao Lou stuck his head out and looked down, of course he didn't dare to climb down from the fifth floor by stepping on the window sill... He didn't want to fall and be paralyzed.

Yu Hanjiang gave him a "go downstairs and wait for me" gesture, and walked quickly to the door of Shuxianglou.

Team Yu did not know where to find an iron wire, and after tossing for a while, the door was unlocked. Xiao Lou was waiting at the door. Seeing Team Yu opened the door, he couldn't help but think - thanks to Yu Hanjiang being a police officer, 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 the skills of unlocking. He likes to study these gadgets."

Xiao Lou nodded and didn't ask any further questions. He and Yu Hanjiang turned around and came to the school gate.

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

Xie Xinghe came very early today, and it was strange that a black gauze was tied outside his school uniform - the black gauze meant to commemorate the deceased, and the person he was commemorating was obviously Ying Xiaoya, who fell to his death yesterday.

Xiao Lou couldn't help but be confused when he saw this. Judging from Xie Xinghe's confession, his relationship with Ying Xiaoya is very general. But he put on the black gauze today, at least it shows that he is very concerned about Xiaoya's death.

Not long after, Yi Ru and Yu Hui also came, also wearing black gauze on their arms.

The three of them met at the school gate and couldn't help but be stunned.

Yu Hui frowned, took a step forward, glanced at Xie Xinghe's arm, and said, "Xie Xinghe, what are you wearing this for? Our Xiaoya doesn't need you to pay homage!"

Xie Xinghe said with a blank face: "I know that your hostility towards me is difficult to resolve. However, I have been with Xiaoya for three years, and her death... I am also very sad."

What more Yu Hui wanted to say, Yi Ru said, "Don't be arguing, do you want people to watch at the school gate?"

Yesterday, Yi Ru was emotionally broken and cried for a long time in front of the police. After a whole night of adjustment, she has returned to normal. However, she has thick dark circles under her eyelids and looks tired, obviously not resting well.

Yu Hui walked forward with a cold face.

The three entered the Chongwen Building in the third year of senior high school one after the other, silent on the way.

The other students should have nothing to do with the case, and the content of the discussion has no 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 appeared in the chemistry teacher of the third (3) class of high school.

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

She has neat short hair, black pencil pants, a white shirt, a long khaki trench coat, and high-heeled shoes. She walks gracefully, as if she had studied professional dance, with a slender and straight body. The pose looks very temperamental.

The security guard greeted her: "Mr. Qin, are you coming to work?"

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

Xiao Lou and Yu Hanjiang immediately became alert.

Teacher Qin, the security guard greeted her specially, as if 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 chemical office on the third floor of Xingzhi Building, and as soon as she walked into the office, a colleague said to her, "Wei Wei, you are really lucky, thank you for your leave yesterday, don't you know? Class 3 has a Students commit suicide by jumping off the building!"

Qin Wei was stunned for a while, then turned around suddenly: "What? Who jumped off the building?"

The colleague said: "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 be? I remember that girl was very serious in her studies. It was just an accident that she didn't pass the test this time. I would like to encourage her. If she failed the test once, there was 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.

Chemistry teacher Qin Weiwei, either has a deep scheming and first-class acting skills, or is really innocent. He doesn't know what happened to Ying Xiaoya who jumped off the building - what kind of situation is it? she.

Today's morning reading class in Class 3 is a Chinese class, and the class teacher asked everyone to memorize the text for half an hour.

The first class at 8:10 happened to be a chemistry class. Qin Weiwei prepared the textbook and walked out of the office to the direction of the third grade (3). Yu Hanjiang and Xiao Lou came out from the bathroom opposite the office, looking at her back, Yu Hanjiang whispered, "Follow Qin Weiwei, I'll wait for the police at the school gate, and come back to you later."

Xiao Lou nodded and followed Qin Weiwei calmly.

During class time, there were many teachers coming and going in the air corridor, and she did not notice Xiao Lou behind her.

Qin Weiwei walked into the classroom with her textbooks—I don't know if it was because she didn't experience the accident that Ying Xiaoya fell from a building yesterday, or because her psychological quality was really strong. She taught this class very seriously, even if many students in the audience Absentmindedly, she also did her job as a teacher and finished the class.

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

Xiao Lou couldn't help touching his chin in doubt... Is such a teacher really a cruel murderer?

***

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

The police are indeed here!

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

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

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

The police turned on the tape recorder and asked the PE teacher while recording: "When Ying Xiaoya had an accident yesterday, who was the person who called you during the PE class?"

The physical education teacher was stunned, and quickly replied: "Mr. Qin. Didn't she change classes with me? I called and asked about the students' situation. I asked her where she was, and she said that she wanted to take her father to the hospital. Do an inspection."

"Are you familiar with Teacher Qin? Did you see her yesterday?"

"I know very well. We were assigned to this school together five years ago, and we have been taking the same class. When she has something to do, she will change classes with me." The physical education teacher paused and said, "Yesterday she asked for leave, I Haven't seen her."

"What kind of person do you think she is?"

"Very cautious, attentive, and beautiful. Teacher Qin is very popular at school."

The police called the security guard again and asked some questions: "Did you see Teacher Qin yesterday?"

The security guard looked puzzled: "I haven't seen it. Didn't she ask for leave? I saw her coming to work this morning."

"You are keeping the key on the rooftop of Xingzhi Building? Have you ever lent it to anyone?"

"No..." The security guard suddenly thought of something, stood up and said, "However, I accidentally lost a whole bunch of keys while patrolling the school last month. Teacher Qin returned it to me after picking it up."

The two police officers looked at each other: "Are you sure it's Teacher Qin?"

Security guard: "Of course, after she returned it to me, I invited her to a meal to express my gratitude!"

After the case related personnel walked out the door, the two policemen began to discuss in a low voice.

The captain said: "This teacher Qin has a big problem. She brought the surveillance data back yesterday. She happened to come to the school when the deceased had an accident, proving that she was lying. She also picked up the key and returned it to the security guard. Besides, the deceased The poison was organophosphate, and she bought a bottle of organophosphate when she was shopping for medicine last week."

The policewoman said, "The poison in the deceased was found in Yu Hui's chocolate. Yu Hui is also very suspicious."

The captain said: "Yu Hui should be fine, the chocolates are likely to be packaged, and they will be called for the first trial later."

At this time, a policeman happened to push the door and came in, holding a half bottle of organophosphorus and an autograph book in his hand.

The young detective said, "Boss, sure enough, we found poison in the chemical laboratory."

The captain glanced at it and said, "You two, go to Class 3 (3) of senior high school immediately, and call Qin Weiwei, Yu Hui, and Xie Xinghe all three suspects after class!"

Yu Hanjiang's cloak time was almost up, he had to leave the office and quickly return to the third grade (3) class.

Xiao Lou was eavesdropping at the back of the classroom, and Yu Hanjiang walked over and whispered in his ear: "The police have already arrived, and the suspect will be interrogated after class. You go ahead and prepare, follow them to listen to the interrogation, and I will cover you outside. ."

Xiao Lou nodded and returned to Xingzhilou with Team Yu.

The two hid in the bathroom, and Yu Hanjiang put himself

What he heard was simply repeated to Xiao Lou. After the suspect brought him, 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: "Officer, didn't you ask me yesterday? What else do you want to ask?"

Policeman: "This box of your sandwiched 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 own sister! This chocolate must have been stolen!"

Policeman: "Since you are brother and sister, why don't you make your relationship public so that people will misunderstand that you are in a relationship?"

Yu Hui scratched his hair irritably and said, "I'm the same age as her, only three days older than her, this girl has never called me brother since she was a child. Two people in the same class, it's embarrassing to let the classmates know that we are brother and sister. Okay? So at school, we both called each other by name, and I didn't expect to be misunderstood!"

The police asked: "Did she stay in your house since she was a child? How are your feelings?"

Yu Hui said: "When she was seven years old, her parents divorced. Her parents were both out of town, so they didn't care about her much. They took care of her in our house. We grew up together, and our relationship is closer than that of brothers and sisters."

He paused, then followed: "So Xiaoya's suicide note must not be written by her! I'm sorry parents, parents like that are sorry! She really wants to commit suicide, the most sorry person should be my parents!"

The police then asked, "Has your chocolate been touched by anyone?"

Yu Hui: "I don't know. I bought that box of chocolates at the supermarket last week. I've kept it in my school bag for a week."

Policeman: "Have you eaten Ying Xiaoya?"

Yu Hui thought about it carefully: "I did give her a chocolate when I was running yesterday."

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, but didn't come back to my house. We used to go to school together. , Xiaoya gets up very early every day, and it's strange to me that she's late!"

The police told Yu Hui to go back. He had no motive for murder and had never been exposed to poison, so although the chocolate came from his hands, his suspicion was the least.

More suspicious are Xie Xinghe, who checked the signature of the potion in the experimental class, and the chemistry teacher who bought the potion directly.

******

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

Xie Xinghe was quickly brought into the interrogation room.

The police asked directly: "In the chemistry experiment class last Wednesday afternoon, your class was in the No. 3 laboratory, right?"

Xie Xinghe: "Yes."

Policeman: "Did the experimental class teach about organophosphorus? The chemistry teacher gave you a bottle of medicine as a demonstration?"

Xie Xinghe looked calm: "Yes."

Policeman: "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 squad leader. It is my duty to check the instruments and reagents after completing the experiment."

Policeman: "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 had a calm expression, not like a lie, and his testimony was indeed flawless, so he went back first and called the chemistry teacher in.

Qin Weiwei, who is currently the most suspect, walked into the interrogation room with a look of confusion on his face.

She sat down and said doubtfully, "Officer, what do you want to know?"

The policeman said: "Didn't you ask for leave yesterday? However, we went back and checked the surveillance for the whole day. The surveillance records at the school gate show that you went back to the school at around 11:20 and left at around 11:40."

When Xiao Lou heard this, he was slightly startled, 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 and came back to get it."

Police: "In other words, when Ying Xiaoya committed suicide by jumping off the building, you were actually at school."

Qin Weiwei's expression changed, and she said, "You shouldn't doubt me, right?!"

The policeman looked serious: "Please answer the question and cooperate with the investigation."

Qin Weiwei took a deep breath and said, "I was in school during this time, and I called the physical education teacher to ask about the students. He said that he was organizing students to play basketball. I didn't know that Ying Xiaoya jumped off the building. Get your health insurance card and leave."

Policeman: "Last month, the security guard's key was lost. Did you pick it up and give it back to him?"

Qin nodded slightly: "That's right."

Policeman: "So, it's entirely possible for you to match a key on the rooftop?"

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

Policeman: "Did you buy this bottle of organophosphorus?"

Qin Weiwei: "Yes, I taught the students about organic phosphorus and inorganic phosphorus, bought a bottle and let them recognize this poison so as not to accidentally come into contact with it, and I also taught them the first aid knowledge in case of organic phosphorus poisoning. Wait, why are you asking this all of a sudden?"

police:"

Organophosphorus was found in the blood of the deceased, who had been poisoned before she fell. And half of the medicine in the chemical laboratory was taken away. Xie Xinghe said that the medicine was still full when he checked, and you are the only person who can go to the laboratory and take the medicine at will. "

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's face is full of disbelief: "Officer, you have made a mistake! I really didn't take any medicine, and I didn't get 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 placed on her hand.

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

Xiao Lou hurriedly followed the police out.

Yu Hanjiang pretended to pass 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 picked up the security guard's key. When the incident happened, she happened to go back to school and called the physical education teacher... She also happened to buy organophosphorus poison."

At this time, the effect of Xiao Lou's invisibility cloak was not over yet, so Yu Hanjiang could only hear what he said, but couldn't see where he was.

However, Team Yu was very calm, and when he talked to the air, he still looked calm: "So, the police took her back to investigate?"

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 feel right."

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

[The reasoning result of the secret room of Hearts 3: The murderer is 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 for punishment. 】

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

They said in unison, "Qin Weiwei is not the murderer."

Yu Hanjiang looked at Xiao Lou with admiration and said, "How did you analyze it?"

Xiao Lou sorted out his thoughts and said, "First, Mr. 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 had Second, she is a chemistry teacher, if she really wants to poison Ying Xiaoya, there are many ways, there is no need to take poison from the chemistry laboratory and leave such a big handle."

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

Looking back at Yi Ru's confession yesterday, in the physical education class, the boy was playing ball, and the two returned to the teaching building. Ying Xiaoya said that she was very hungry and asked Yi Ru to buy food. During the period when Yi Ru went to the canteen to buy potato chips, Maybe Ying Xiaoya was too hungry to bear, so she ate a piece of chocolate.

During the run in the language class, Yu Hui once stuffed a chocolate into Ying Xiaoya, and Ying Xiaoya put it in her pocket.

Xiao Lou happened to notice this scene at that time - what Yu Hui gave her was a spherical chocolate with a diameter of about 3cm, and it was covered with golden candy wrappers. Ying Xiaoya should have eaten this one.

The poison content of a sandwich chocolate is very low, and it will not lead to direct death of the user, but acute organophosphorus poisoning will still cause miosis, muscle tremors and other reactions, as long as it is rescued 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 fractured skull 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 poison dose, Yu Hanjiang was more convinced of his inference.

He whispered, "Yu Hui's chocolate has been manipulated. On the surface, Qin Weiwei has plenty of time to commit the crime, and all the suspects are directed at her... However, the police overlooked a key point."

Yu Hanjiang looked at Xiao Lou and asked him a question: "If you wanted to kill someone, would you push him downstairs after you poisoned him?"

Xiao Lou's eyes suddenly lit up.

——Yes, poisoning and falling from a building are all methods that can kill people, so 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 "sandwiched chocolate", a food with a very small amount of hidden poison, and put it in Yu Hui's chocolate... What if Yu Hui eats it? Wasn't the poison wrong Yu Hui? A better method would be to poison Ying Xiaoya's diet in large quantities directly and without knowing it, to ensure that she can be poisoned to death.

And if the murderer wanted to push Ying Xiaoya down from the roof and fall to his death, copy the suicide note, and create the illusion of Ying Xiaoya committing suicide, then there is no need to add poison, but let the police detect poison from Ying Xiaoya's body.

Xiao Lou touched his chin and thought for a moment, then 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: "That's right."

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

——The Ying Xiaoya case can actually be broken down.

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 to eat. Therefore, if the sandwich chocolate is dropped, there is a 50% probability of poisoning. When it comes to Yu Hui, there is a 50% chance of poisoning Ying Xiaoya. Who the poisoner is and what the purpose is, it is still unclear.

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

No one will eat dozens of chocolates in one go. Half a bottle of organophosphorus is scattered among dozens of chocolates. The toxin content of each can't poison people, but it is enough to attract people's attention-perhaps, the poisoner is passing through. This means reminds something.

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

The second part of the case is the fall from the building.

Yu Hanjiang inspected the scene on the roof yesterday, and the footprints on the roof were disordered. It is very possible that there was a second person at the scene. This person pushed Ying Xiaoya downstairs, which directly led to Ying Xiaoya's death. Moreover, this person copied the handwriting very cleverly and forged a "suicide note" for Ying Xiaoya, causing Ying Xiaoya to "suicide".

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 from 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's suicide - Ying Xiaoya's suicide note forged by the murderer became the biggest failure.

Forensic investigators detected the source of the poison. The police identified chocolate, organophosphorus, and laboratories. All suspects pointed to Qin Weiwei, a chemistry teacher.

Although Teacher Qin was taken away for investigation, the police would soon come to the conclusion that she was not the murderer.

Because it doesn't make sense.

No one would be stupid enough to throw a small amount of poison first, then push someone off the roof and forge a suicide note.

The case will be split soon.

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

Yu Hanjiang glanced at Xiao Lou and said, "There was a heavy rain last night, and the school was so chaotic. Today, the school will definitely be cleaned on a large scale. The murderer may destroy the evidence. We have to get ahead of 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 buildings and office buildings of Fenglin High School are equipped with small garbage cans. The garbage that students clean up every day will be concentrated in these small garbage cans, and then the garbage will be collected by the cleaners into the garbage cans behind the playground.

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

Last night, due to the storm, the campus was messy. In the morning, after cleaning the playground, the cleaners collected a lot of leaves, broken branches, broken flower pots and other garbage into the garbage can. This garbage can is full and must be called garbage. The car comes to clean up.

When Yu Hanjiang and Xiao Lou came to the trash can, the cleaners happened to be picking up the trash.

Xiao Lou stepped forward quickly and said to the cleaner, "Auntie, I'm sorry, I'm a first-year teacher. I accidentally threw my important documents into the trash yesterday. Can I look for it here?"

Auntie Qing said: "Oh, what documents? It's too dirty here, don't touch it, teacher, we'll help you find it."

Xiao Lou said nervously: "It's my teacher's qualification certificate. When I threw away the waste paper yesterday, I threw it away without seeing it clearly. Please help me find it. I'll wait here, thank you."

Yu Hanjiang: "..."

Professor Xiao's acting is very good.

With this reason, the two of them can stand by the trash can and observe.

The cleaner's aunt was looking for the certificate for the two of them while digging through the garbage. She said, "I need to check the garbage in the future. You said, what if I can't find such an important certificate."

Xiao Lou nodded: "I was too negligent."

At this moment, Yu Hanjiang's eyes narrowed suddenly: "Wait."

The cleaner was stunned: "What's wrong with the teacher?"

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

It is a pair of women's canvas shoes, the shoe size is 37, which is the same as Ying Xiaoya's shoes.

Seeing this, the cleaner couldn't help but say, "Who lost the shoes? These shoes look pretty new!"

Yu Hanjiang and Xiao Lou looked at each other.

Important evidence has been found.

Ying Xiaoya's footprints on the rooftop were so messy because there were footprints of two people - the other was wearing the same shoes as hers. And the fragments of her scarf were left on the rooftop, and it must have been before she was pushed down that the two clashed.

The killer threw the ill-fitting shoes into the trash because he knew the school's litter box would be cleaned out today.

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

Unfortunately, Yu Hanjiang and Xiao Lou found these shoes.

Prove their just inference is correct.

In Ying Xiaoya's case, there are two murderers in action at the same time!

The author has something to say: Thank you for your overlord tickets, comments and nutrient solution!

90 degree bow thank you!

In the comment area, many little angels are analyzing and discussing, and everyone is very serious. It is the first time to write a reasoning theme, and I am super happy to be recognized.

The truth is about to emerge :)
