When Xiao Lou woke up, Yu Hanjiang was standing by the corridor window, his deep eyes staring into the distance, his brows slightly furrowed, as if he was thinking about something.
Xiao Lou walked over and asked, "Captain Yu, have you made 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 wash of rain. The ground seemed to be covered with a thick red carpet of maple leaves. At the end of the maple forest,
Several recently planted saplings were blown to the ground by the wind. The flower beds under the teaching building were tilted here and there, and many flower pots were broken. The entire campus was in a mess, as if a typhoon had passed through.
At half past six in the morning, the rain had stopped.
At this time, the two of them were supposed to stay at the school gate. There would definitely be new clues on the new day. However, last night they sneaked into Shuxiang Building to investigate and alerted the security guards. The door of Shuxiang Building was locked by the security guards.
Xiao Lou slept very uncomfortable last night. He rubbed his temples with a headache and said, "Class is about to start. How are we going to get out?"
Yu Hanjiang looked calm and pointed at the air conditioning duct outside the window: "Climb out."
Xiao Lou: "..."
In the Hearts Secret Room, Yu Hanjiang showed the same attitude as to pass the Spades Survival Secret Room. He simply opened the window, jumped up, accurately grasped the air conditioning duct with both hands, and stepped on the window sill only 10cm wide with his feet, layer by layer.
Climb down.
Xiao Lou's heart was in his throat.
It's so high, if he misses the mark, he will fall down!
But it turned out that Xiao Lou's worries were unnecessary. Yu Hanjiang seemed to do this kind of thing often - climbing and jumping. The man was familiar with all kinds of buildings and quickly chose the most convenient path and landed steadily on the ground.
Go up and look 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 become paralyzed.
Yu Hanjiang gave him a "come downstairs and wait for me" gesture and quickly came to the door of Shuxiang Building.
Captain Yu found a piece of wire from nowhere, and after a while of struggling, he unlocked the door. Xiao Lou was waiting at the door, and when he saw Captain Yu opening the door, he couldn't help but think - thanks to Yu Hanjiang being a policeman, if he wanted to become a flying sky
Big thief, I guess no one can stop him, right?
Yu Hanjiang seemed to see Xiao Lou's doubts. While restoring the door lock, he explained: "When I was in the police academy, a senior taught me the skills of unlocking locks. He liked to study these gadgets very much."
Xiao Lou nodded and without asking any questions, he and Yu Hanjiang turned around and came to the school gate.
Starting at seven o'clock, students came to school one after another.
Xie Xinghe came very early today, and what's strange is that there is a black gauze tied outside his school uniform - the black gauze means commemorating the dead, and the person he is commemorating is obviously Ying Xiaoya, who fell to her 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 was very ordinary. But the fact that he wore a black veil today at least showed that he was very concerned about Ying 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 and took a step forward, glanced at Xie Xinghe's arm, and said, "Xie Xinghe, why are you wearing this? Our Xiaoya doesn't need you to pay homage to her!"
Xie Xinghe said expressionlessly: "I know it is difficult to resolve your hostility towards me. However, Xiaoya and I have been classmates for three years, and her death... I am also very sad."
Yu Hui wanted to say something else, but Yi Ru said: "Stop arguing, do you want people to watch at the school gate?"
Yesterday, Yi Ru had an 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 were thick dark circles under her eyelids and she looked tired, obviously not resting well.
Yu Hui walked forward with a cold face.
The three of them entered Chongwen Building, where the third grade students were in high school, one after another. They were silent on the way.
The other students should have nothing to do with the case, and there was no valuable information in the discussion. 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 from Class 3 of Senior High School to show up.
At 7:25, with 5 minutes left before the morning reading class, a tall female teacher walked quickly into the school gate.
She has smart, ear-length short hair, wearing black pencil pants and a white shirt, paired with a khaki long windbreaker, and high heels. She walks with an elegant posture, as if she has learned professional dance, with a slender and straight body.
The posture looks very elegant.
The security guard greeted her: "Teacher Qin, are you coming to work?"
The female teacher smiled and nodded to the security guard, then walked quickly to Zhilou.
Xiao Lou and Yu Hanjiang immediately became alert.
Teacher Qin, the security guard greeted her specifically, as if to remind the challenger that this was the chemistry teacher from Class 3 who took 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 entered the office, a colleague said to her: "Weiwei, you are really lucky. Thank you for asking for leave yesterday. You didn't know, right? There was a guy in class 3.
The student committed suicide by jumping off the building!"
Qin Weiwei was stunned, then suddenly turned around: "What? Who jumped off the building?"
A colleague said: "In this monthly exam, Ying Xiaoya ranks last in the whole grade."
The expression on Qin Weiwei's face was full of shock: "How could it be? I remember that girl studied very seriously. She didn't do well in the exam this time. It was just an accident. I also want to encourage her. If she failed in the exam once, there is no need to commit suicide by jumping off the building.
?”
Xiao Lou and Yu Hanjiang pretended to be teachers passing by and saw the situation in the office clearly.
Chemistry teacher Qin Weiwei is either very scheming and has top-notch acting skills, or he is really innocent and doesn't know about Ying Xiaoya jumping off the building - which case it is, we can't draw a conclusion yet. The police will definitely come to investigate today.
she.
Today's morning reading class for Class 3 is a Chinese class. 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 teaching materials and walked out of the office in the direction of Class 3 of Senior High School. Yu Hanjiang and Xiao Lou came out of the bathroom opposite the office and looked at her back. Yu Hanjiang
He whispered, "Follow Qin Weiwei. I'll wait for the police at the school gate and come back to find you later."
Xiao Lou nodded and followed Qin Weiwei calmly.
During class time, there were many teachers coming and going in the corridor, but she did not notice Xiao Lou behind her.
Qin Weiwei walked into the classroom with her textbooks - I don't know whether it was because she had not experienced Ying Xiaoya's accident yesterday, or because her psychological quality was really strong. She taught this class very seriously, even though many students in the audience were confused.
Absentmindedly, she did her job as a teacher and finished the class.
Xiao Lou is also a teacher. From the perspective of peers, Teacher Qin's class is first-rate. Her chalk writing is correct and timeless. She never talks nonsense in class and prepares lessons well - the 45-minute class is clearly organized.
, the priorities are clear, and the key knowledge is explained clearly, and it can almost be used as a demonstration class directly.
Xiao Lou couldn't help but touch his chin in confusion... Could such a teacher really be a cruel murderer?
***
At this time, 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 were the same as yesterday. Obviously, after the forensic doctor took the body back yesterday, he conducted an autopsy, confirmed the cause of death, and told the criminal police all the information he knew - these police officers came to the door with a lot of clues.
They first found the principal and vacated an office in Xingzhi Building. Then they called the physical education teacher from Class 3 and the security guard on duty yesterday to inquire.
The office door was about to close, and Yu Hanjiang immediately put on his invisibility cloak and went in to listen.
The police turned on the recorder and asked the physical education teacher while recording: "During the physical education class yesterday, when Ying Xiaoya had an accident, who called you?"
The physical education teacher was stunned and quickly replied: "It's Teacher Qin. Didn't she switch classes with me? She called and asked about the students' situation. I asked her where she was, and she said she was taking her father to the hospital.
Get checked."
"Are you familiar with Teacher Qin? Did you see her yesterday?"
"We are very familiar. We were assigned to this school together five years ago, and we have always taught the same class. When she has something to do, she changes classes with me." The physical education teacher paused and said, "She asked for leave yesterday, and I
Never seen her."
"What kind of person do you think she is?"
"She is very cautious, very attentive, and good-looking. Teacher Qin is very popular in school."
The police called the security guard over and asked some questions: "Did you see Teacher Qin yesterday?"
The security guard looked confused: "I haven't seen her before. Didn't she take leave? I saw her coming to work this morning."
"You are keeping the key on the rooftop of Xingzhi Building, right? Have you ever lent it to others?"
"No..." The security guard suddenly thought of something, straightened up and said, "However, I accidentally lost a bunch of my keys while patrolling the school last month. Teacher Qin picked them up and gave them back to me."
The two policemen looked at each other: "Are you sure it's Teacher Qin?"
Security guard: "Of course, after she returned it to me, I treated her to a meal as a token of my gratitude!"
After the people involved in the case walked out of 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 accident happened to the deceased, which proves that she was lying. She also picked up the key and returned it to the security guard. Moreover, the deceased
The poison in her body was organophosphorus, 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, and Yu Hui is also highly suspected."
The captain said: "There should be nothing wrong with Yu Hui. The chocolate may have been swapped. We will ask them to come over for a trial later."
At this time, a policeman pushed open the door and came in, holding half a bottle of organophosphorus and a signature book.
The young detective said: "Boss, poison was indeed found in the chemical laboratory."
The captain took a look and said: "You two, go to class 3 (3) of high school immediately and call the three suspects Qin Weiwei, Yu Hui, and Xie Xinghe over after class!"
Yu Hanjiang's cloak time was almost up, so he had to leave the office and quickly return to class 3 (3).
Xiao Lou was eavesdropping at the back of the classroom. Yu Hanjiang walked over and whispered in his ear: "The police are already here. The suspects will be interrogated after class. You go there in advance to prepare and follow them to listen to the interrogation. I will cover you outside."
.”
Xiao Lou nodded and returned to Xingzhi Tower with Captain Yu.
The two hid in the bathroom. Yu Hanjiang briefly repeated what he had just heard to Xiao Lou. After the suspect arrived, Xiao Lou immediately put on his 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? Is there anything else you want to ask?"
Police: "Your box of sandwich chocolates is full of organophosphorus poisons. How do you explain it?"
Yu Hui's face was full of horror: "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 to death? Damn it! Are you kidding me? I regard her as my sister! This chocolate must have been stolen!"
Policeman: "Since you are brother and sister, why don't you make your relationship public so that others may 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 hasn't called me brother since she was a child. We are in the same class. It's embarrassing for our classmates to know that we are siblings.
Okay? So in school, we both called each other by our first names, and we didn’t expect that we would be misunderstood!”
The police asked: "Has she stayed at your house since she was a child? How is your relationship?"
Yu Hui said: "Her parents divorced when she was seven years old. Her parents were out of town and didn't care much about her. They left her in our home to take care of her. We grew up together and our relationship is closer than that of real brothers and sisters."
He paused and then said: "So Xiaoya's suicide note was definitely not written by her! I'm sorry to my parents, such parents are so sorry! She really wanted to commit suicide, and the people I'm most sorry for 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 in the supermarket last week, and I've kept them in my schoolbag for a week."
Police: "Have you given Ying Xiaoya food?"
Yu Hui thought carefully: "I did give her a chocolate when we were 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 an eighteenth birthday gift. She was very happy. She went back to stay with her mother in a hotel at night instead of my house. We used to go to school together.
, Xiaoya gets up very early every day, and I’m surprised that she’s late!”
The police let Yu Hui go back. He had no motive for murder and had never been exposed to poisons, so although the chocolate came from his hands, his suspicion was the smallest.
Even more suspicious are Xie Xinghe, who checked the signature of the medicine in the experimental class, and the chemistry teacher who directly purchased the medicine.
******
[Chapter 29, Bloody Maple Leaf 8-Suspect’s Testimony]
Xie Xinghe was quickly taken into the interrogation room.
The policeman asked directly: "Last Wednesday afternoon's chemistry experiment class, your class was held in Laboratory No. 3, right?"
Xie Xinghe: "Yes."
Police: "Did the experimental class teach about organophosphorus? The chemistry teacher showed you a bottle of medicine?"
Xie Xinghe looked calm: "Yes."
Policeman: "You were the one who checked the medicine and put it back in the cabinet in the end?"
Xie Xinghe was silent for a moment and said: "I am the squad leader. It is my responsibility to check the instruments and reagents after completing the experiment."
Police: "Half the bottle of medicine is missing. Did you take it away?"
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 very calm and did not look like he was lying. Moreover, there were indeed no flaws in his testimony, so they asked him to go back first and called in the chemistry teacher.
Qin Weiwei, who is currently the most suspected, had a look of confusion on his face when he walked into the interrogation room.
She sat down and asked 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 all day long. The surveillance records at the school gate showed that you returned to school around 11:20 and left 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 back to get it."
Police: "In other words, you were actually at school during the time when Ying Xiaoya committed suicide by jumping off the building."
Qin Weiwei's expression changed and he said, "Don't you doubt me?"
The policeman looked serious: "Please answer the questions and cooperate with the investigation."
Qin Weiwei took a deep breath and said: "During this period, I was indeed at school. I also 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 from the building. I
I took my medical insurance card and left."
Policeman: "Last month, the security guard's key was lost. Did you pick it up and return it to him?"
Qin nodded slightly: "That's right."
Policeman: "So, it's entirely possible that you could get a key to the rooftop?"
Qin Weiwei's face was extremely ugly: "What do you mean? What do I do with the key to the rooftop? After I picked up the key, I had to rush to class, so I put it in the office first, and then 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. I bought a bottle to help them understand this poison so as not to accidentally come into contact with it. I also taught them the first aid knowledge for organophosphorus poisoning.
…Wait a minute, why are you asking this suddenly?”
Police: "Organophosphorus was found in the deceased's blood. She was poisoned before she fell. Half of the medicine in the chemical laboratory was taken away. Xie Xinghe said that when he checked, the medicine was still full, and he could go to the laboratory as he pleased.
The only person who took away the potion was you."
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 was full of disbelief: "Officer, you made a mistake! I really didn't take any medicine or 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 return to the police station for investigation."
Before she could finish her words, a cold handcuff was placed on her hand.
The police took Qin Weiwei away as a criminal suspect with an arrest warrant.
Xiao Lou hurriedly followed the police out of the house.
Yu Hanjiang pretended to be passing by and walked into the bathroom, and 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. She happened to go back to school at the time of the incident and called the physical education teacher... and happened to buy organophosphorus poisons."
At this time, the effect of Xiao Lou's invisibility cloak had not ended, so Yu Hanjiang could only hear him speak, but could not see where he was.
However, Captain Yu was very calm and remained calm when talking to the air: "So, the police took her back for investigation?"
At this moment, 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 feel something is wrong."
At this moment, prompts popped up in the floating boxes of the two people at the same time——
[Result of 3 Hearts secret room reasoning: The murderer is chemistry teacher Qin Weiwei? Yes/No.]
[Note: If the reasoning is wrong, the challenge will fail and you will be sent to the nightmare chamber to receive punishment. 】
The two looked at each other and pressed "No" at the same time.
They all 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, Teacher Qin has the key to the chemistry laboratory. If she wants to take away the organophosphorus poisons, she does not need to pick the lock. But when we checked the laboratory last night, we found that the door lock was
There are traces of prying; secondly, she is a chemistry teacher. If she really wanted to poison Ying Xiaoya, there are many ways. There is no need to get poison from the chemistry laboratory and leave such a big clue."
He paused and continued: "According to the forensic test results, Ying Xiaoya was poisoned, and the source of the poison was the chocolate given to her by Yu Hui. However, the poison that sandwich chocolate can hold is very limited. This dose of organic
Phosphorus is not fatal. Unless Ying Xiaoya is so hungry that she eats the whole box of chocolates - but there are a lot of chocolates left in Yu Hui's schoolbag, which means Ying Xiaoya should only eat one or two."
Carefully review Yi Ru's confession yesterday. During the physical education class, the boys were playing ball. The two returned to the teaching building. Ying Xiaoya said she was very hungry and asked Yi Ru to buy food. When Yi Ru went to the canteen to buy potato chips,
Ying Xiaoya might have been too hungry, so she ate a chocolate.
During the Chinese language class, Yu Hui once stuffed a chocolate for Ying Xiaoya, and Ying Xiaoya put it in her pocket.
Xiao Lou happened to notice this scene at that time - what Yu Hui thrust into her was a spherical chocolate about 3cm in diameter, wrapped in golden candy wrapper, and it was probably this one that Ying Xiaoya ate.
The poisonous content of a sandwich chocolate is very low and will not cause direct death to the user. However, acute organophosphorus poisoning will still cause reactions such as miosis and muscle tremors. As long as you get rescued in time, you 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 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 poison dosage, Yu Hanjiang became more convinced of his inference.
He whispered: "Yu Hui's chocolates have been tampered with. On the surface, it seems that Qin Weiwei has enough time to commit the crime, and all the suspicions point directly to her... However, the police ignored one key point."
Yu Hanjiang looked at Xiao Lou and asked him a question: "If you wanted to kill someone, would you poison the person and then push the person downstairs?"
Xiao Lou's eyes suddenly lit up.
——Yes, poisoning and falling from a building are all ways to kill people. There is no need to use them twice!
——This is simply "superfluous".
If the murderer wanted to poison Ying Xiaoya, first of all, he shouldn't have used "sandwich chocolate", a food with a very small amount of poison, and put it in Yu Hui's chocolate... What if Yu Hui eats it? Wouldn't it?
Poisoned the wrong Yu Hui? A better way is to directly poison Ying Xiaoya's diet 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 of the building and fall to death, copy the suicide note, and create the illusion that Ying Xiaoya committed suicide, there would be no need to go to the trouble of poisoning, and instead let the police detect the 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 they contradicted each other, so there were loopholes left?"
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 testimonies of all the suspects in the past two days.
——Ying Xiaoya’s case can actually be broken down.
The first part is a poisoning case.
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, so if he switches the sandwich chocolate, there is a 50% chance of poisoning her.
If you go to Yu Hui, there is a 50% chance that you will poison Ying Xiaoya. Who is this poisoner and what is his purpose cannot be confirmed yet.
But what can be confirmed is that his method of poisoning did not intend to directly kill Ying Xiaoya.
No one would eat dozens of chocolates in one go. Half a bottle of organophosphorus is dispersed in dozens of chocolates. The toxin content in each chocolate cannot poison people, but it is enough to attract people's attention-perhaps, the poisoner is passing
This method reminds you of something.
Excluding Yu Hui, he loves chocolate and has no motive to poison his sister. Yi Ru and Xie Xinghe are all suspected. The door lock of the laboratory has been broken, and so are all the teachers who know that Yu Hui often sends chocolates to Ying Xiaoya.
suspicion.
The second part of the case is the falling case.
Yu Hanjiang inspected the scene on the roof yesterday. The footprints on the rooftop were disordered. It was very likely that there was a second person on the scene. This person pushed Ying Xiaoya downstairs, directly leading to Ying Xiaoya's death. Moreover, this person was very
Cleverly copying the handwriting, he forged a "suicide note" for Ying Xiaoya, creating the illusion that Ying Xiaoya had committed 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. The murderer forged Ying Xiaoya's suicide note, which turned out to be the biggest failure.
Forensic medicine detected the source of the poison, and the police focused on chocolate, organophosphorus, and laboratories. All suspicions pointed to chemistry teacher Qin Weiwei.
Although Teacher Qin was taken away for investigation, the police would soon conclude that she was not the murderer.
Because it doesn't make sense.
No one would be stupid enough to first inject a small amount of poison, then push the person off the rooftop and forge a suicide note.
The case will be split soon.
One person swapped the package of filled chocolates containing toxins, and the other 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 in such a mess. The campus will definitely be cleaned on a large scale today. The murderer may destroy the evidence. We must get ahead of the murderer."
Xiao Lou also became nervous: "Where does Captain Yu want to search?"
Yu Hanjiang: "The biggest trash can in the corner of the school."
***
There are small trash cans inside the teaching building and office building of Maplewood High School. The garbage that students clean up every day will first be concentrated in these small trash cans, and then the garbage will be collected by the cleaners to the trash can behind the playground.
This trash can should be cleaned every two to three days, and a professional garbage disposal truck will come and remove all the contents.
Due to the violent storm last night, the campus was in a mess. In the morning, after cleaning the playground, the cleaners gathered a large number of leaves, broken branches, broken flower pots and other garbage into the trash can. This trash can was full, so we must call it garbage.
The car came to be cleaned.
When Yu Hanjiang and Xiao Lou came to the trash can, the cleaners were picking up the trash.
Xiao Lou walked forward quickly and said to the cleaner: "Auntie, I'm sorry, I'm a first-grade teacher. I accidentally threw a very important document into the trash can yesterday. Can I look for it here?"
The cleaning lady said: "Oh, what certificate? This place is too dirty. Teacher, please don't touch it. We will help you find it."
Xiao Lou said nervously: "It's my teacher's qualification certificate. When I was throwing away the waste paper yesterday, I threw it away without looking clearly. 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 of them could stand beside the trash can and observe openly.
The cleaner aunt was digging through the garbage and helping them find certificates. She was still muttering: "Trash must be inspected in the future. What should I do if I can't find such an important certificate?"
Xiao Lou nodded: "I was too negligent."
At this moment, Yu Hanjiang's eyes suddenly narrowed: "Wait a minute."
The cleaner was stunned: "What's wrong, teacher?"
Yu Hanjiang walked over and picked up a pair of shoes from a pile of waste paper and messy leaves.
It's a pair of women's canvas shoes, shoe size 37, which is the same as Ying Xiaoya's shoes.
When the cleaner saw this, he couldn't help but said: "Who lost the shoe? These shoes look quite new!"
Yu Hanjiang and Xiao Lou looked at each other.
Important evidence was found.
The footprints left by Ying Xiaoya on the rooftop were so messy because there were two people's footprints - the other person wore the same shoes as hers. And the fragments of her scarf were left on the rooftop, which must have been where she was
Before being pushed down, the two had a conflict.
The murderer threw the ill-fitting shoes into the trash can because the murderer knew full well that the school trash cans would be cleared today.
As long as the garbage truck takes away the garbage, it will be dead without evidence.
Unfortunately, Yu Hanjiang and Xiao Lou found this pair of shoes.
Prove that their inference just now is correct.
In Ying Xiaoya's case, there are two murderers acting at the same time!
