The Secret Chamber of the Card Game

Xie Xinghe was quickly brought into the interrogation room.

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

Xie Xinghe: "Yes."

Policeman: "Did the experiment class talk about organic phosphorus? The chemistry teacher showed 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, then said: "I am the monitor, it is my duty to check the instruments and reagents after the experiment."

Police: "Half a bottle of medicine is missing, did you take it away?"

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

The policemen looked at each other, and found that Xie Xinghe had a calm expression, he didn't seem to be lying, and there were indeed no loopholes in his testimony, so they let him go back first, and called the chemistry teacher in.

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

She sat down and asked in confusion, "Officer, what do you want to know?"

The police 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 went back to school around 11:20 and left 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."

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

Qin Weiwei's expression changed, and he said, "You don't doubt me, do you?!"

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

Qin Weiwei took a deep breath and said: "During this time, I was indeed at school, and I called the physical education teacher to inquire about the situation of the students. He said that he was organizing the students to play basketball. I didn't know that Ying Xiaoya jumped off the building. I I took my medical insurance card and left."

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

Qin Weiwei nodded: "That's right."

Police: "So, it is entirely possible for you to assign a key to the rooftop?"

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

Police: "Did you buy this bottle of organophosphate?"

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

Police: "Organic phosphorus was found in the blood of the deceased. She was poisoned before she fell from the building. Half of the medicines in the chemical laboratory were taken away. Xie Xinghe said that the medicines were still full when he checked, and he could go to the laboratory to do whatever he wanted. The only one who took the potion is you."

Qin Weiwei's face turned pale: "I didn't take it!"

Police: "Ms. Qin Weiwei, you are suspected of killing Ying Xiaoya, here is an arrest warrant."

Qin Weiwei couldn't believe it: "Officer, you made a mistake! I really didn't take any medicine, and I didn't 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.

With an arrest warrant, the police took Qin Weiwei away as a suspect.

Xiao Lou hurriedly followed the police and went out.

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 picked up the security key. She happened to be back at school when the incident happened, and she happened to call the physical education teacher...and she happened to buy organophosphorus poison."

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

However, Captain Yu was very calm, talking to the air with a calm expression: "So, the police took her back to investigate?"

Just 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 does Professor Xiao think?"

Xiao Lou frowned: "I feel something is wrong."

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

[The result of reasoning in 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 chamber 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 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 broken. Traces of prying; second, she is a chemistry teacher, if she really wants to poison Ying Xiaoya, there are many ways, there is no need to get the 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 Yu Hui gave her. However, the poison that can be contained in the sandwich chocolate is very limited, and this dose is organic." Phosphorus is not fatal. Unless Ying Xiaoya is so hungry that she eats up a 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."

Carefully review Yiru’s confession yesterday. At that time, in PE class, the boys were playing ball. When the two returned to the teaching building, Ying Xiaoya said that she was very hungry and asked Yiru to buy food. Perhaps Ying Xiaoya was too hungry, so she ate a piece of chocolate.

When doing exercises in Chinese class, Yu Hui once stuffed Ying Xiaoya with a piece of chocolate, and Ying Xiaoya put it in his pocket.

Xiao Lou happened to notice this scene at the time - what Yu Hui stuffed her was a spherical chocolate with a diameter of about 3cm, wrapped in golden candy wrappers, and it was probably this one that Ying Xiaoya ate.

The poisonous content of a sandwich chocolate is very low, and it will not cause the direct death of the user, but acute organophosphate poisoning will still cause reactions such as miosis and muscle tremors, as long as the timely rescue is all right.

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 became more confident in his deduction.

He whispered: "Yu Hui's chocolate has been tampered with. On the surface, Qin Weiwei has enough time to commit the crime, and all the suspicions are directed at her... But, the police ignored 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 poisoning him?"

Xiao Lou's eyes suddenly lit up.

——That's right, 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 wants to poison Ying Xiaoya to death, first of all, he shouldn't use "sandwich chocolate", which contains very little poison, and put it in Yu Hui's chocolate... What if Yu Hui eats it?Could it be that he poisoned Yu Hui by mistake?A better method is to directly poison Ying Xiaoya's diet in large quantities without anyone noticing, guaranteeing that the poison will kill her.

And if the murderer wanted to push Ying Xiaoya down from the roof and fall to her death, copying the suicide note to create the illusion of Ying Xiaoya committing suicide, then there was no need to go to the trouble of poisoning, 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 the two contradicted each other, so there was a loophole?"

Yu Hanjiang's eyes were deep: "That's right."

This was something Yu Hanjiang finally figured out after carefully sorting out all the clues and the testimony of all the suspects in the past two days.

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

The first part is a poisoning case.

The other party doesn't necessarily want to poison Ying Xiaoya, because the method of poisoning is through Yu Hui's chocolates. The poisoner knows that Yu Hui often gives Ying Xiaoya chocolates to eat, so there is a 50% chance of poisoning if the sandwich chocolate is dropped To Yu Hui, there is a 50% chance of poisoning Ying Xiaoya.Who this poisoner is and what his purpose is is yet to be confirmed.

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 is not enough to kill people, but it is enough to attract people's attention—perhaps, the poisoner is passing 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 suspects, the door lock of the laboratory was broken, and all the teachers who knew that Yu Hui often gave Ying Xiaoya chocolates were also suspects.

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

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

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

Unfortunately, he/she didn't know that Ying Xiaoya had been poisoned before she fell from the building.

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

The forensic doctor tested the source of the poison, and the police targeted chocolate, organic phosphorus, and the laboratory. All the suspects pointed to Qin Weiwei, a chemistry teacher.

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 inject a small amount of poison first, then push people off the roof and forge suicide notes.

The case will be split soon.

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

Yu Hanjiang took a look at Xiao Lou and said, "Last night, there was a heavy rain, and the school was in such a mess. Today, the school will definitely be cleaned up on a large scale. The murderer may destroy the evidence. We must get ahead of the murderer."

Xiao Lou also became nervous: "Where does Team 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 Fenglin High School. The garbage that students clear up every day will be collected in these small trash cans first, and then the garbage will be collected by the cleaners to the trash cans behind the playground.

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

Due to the violent storm last night, the campus was in disarray. In the morning, after cleaning the playground, the cleaners collected a large number of leaves, broken branches, broken flowerpots and other garbage into the trash can. This trash can is full and must be called trash The car came to clean it up.

When Yu Hanjiang and Xiao Lou came near the garbage bin, the cleaners were just picking up the garbage outside.

Xiao Lou stepped forward quickly, and said to the cleaner, "Auntie, I'm sorry, I'm a teacher in the first grade, and I accidentally threw a very important document into the trash can yesterday, can I look for it here?"

The cleaning aunt said: "Oh, what certificate? It's too dirty here, teacher, please don't touch it, we will help you find it."

Xiao Lou said nervously: "It's my teacher qualification certificate. When I threw away the waste paper yesterday, I didn't see it clearly and threw it away. 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 beside the trash can and observe openly.

Auntie the cleaner was digging out the garbage while helping them find the certificate, and she was still muttering: "In the future, the garbage will be inspected. Tell me, what if such an important certificate cannot be found."

Xiao Lou nodded: "I was too negligent."

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

The cleaner was stunned: "What's wrong, 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 was a pair of ladies' canvas shoes, size 37, which was the same as Ying Xiaoya's shoes.

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

Yu Hanjiang and Xiao Lou looked at each other.

Important evidence has been found.

The reason why Ying Xiaoya's footprints on the roof are so messy is because there are two footprints - the other party wore the same shoes as hers.Fragments of her scarf were left on the roof, and there must have been a conflict between the two before she was pushed down.

The murderer threw the ill-fitting shoes into the trash because the murderer knew full well that the school's trash cans would be cleared today.

As long as the garbage truck takes away the garbage, it is dead without proof.

Unfortunately, Yu Hanjiang and Xiao Lou found these shoes.

Prove that their inference just now is correct.

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