Panda Criminal Investigation Team

but two days later,

When the identification results of the evidence come out,

Everything has been settled.The bag of white powder was identified as high concentration of thallium sulfate,

Thallium sulfate was found in plastic vials and plastic droppers,

Two more fingerprints were collected on disposable plastic gloves,

Both belong to Yang Ying,

Also consistent with the fingerprint on the fan control box.

When I went to X University to arrest Yang Ying,

She was still taking economics class as if nothing had happened.Before leaving, she calmly asked her roommates to take notes for her, and agreed that she would come back to have dinner with them in the evening,

But when she saw these evidences, she knew that she was going to miss the appointment.

to the police station,

Yang Ying went straight into the interrogation room,

Not long after, she shivered: "Can you turn off the air conditioner? I feel a little cold."

"Sorry, I didn't turn on the air conditioner."

Cheng Bin replied without raising his head.The indoor temperature is not low,

There are actually 24 five degrees.

Yang Ying's lips trembled,

Rubbing his hands together, he said, "I never thought of killing someone,

I just want to drive her out of the bedroom,

I didn't know this thing was so poisonous..."

Cheng Bin finally raised his head and glanced at her,

Yang Ying quickly cast a pleading look at him,

The thin girl had a pale face, and she looked quite pitiful: "Since she lost her hair, I haven't taken poison anymore,

real,

I just wanted to play a joke on her at first..."

But Cheng Bin ignored her excuse: "Where did the poison be placed?"

"In the book."

"How did it happen?"

"Pour a little powder into a bottle, add water to mix well, and then use a cotton swab to apply to the page."

"You don't mind the trouble."

"Occasionally, use a rubber-tip dropper to suck up the water before dripping."

"You're afraid that the book will wrinkle if you get wet with too much water, so it looks suspicious." Cheng Bin asked expressionlessly. He never knew how to be sympathetic to weak species.

Yang Ying didn't answer directly, but continued to defend herself: "I really didn't know it would happen, I thought she would just have diarrhea or something. I don't have a good grade in chemistry, so I really don't understand these... At that time, I thought, if If she always has diarrhea at school, she will go home because she always snores when she sleeps. She is a local, and the family conditions are good, even if she rents a house near the school, there is no problem."

Cheng Bin watched her without speaking, just turning the ballpoint pen in his hand.Yang Ying waited for a while, and then said: "Since she was hospitalized, I put away the poisoned book. I was afraid that she would be poisoned again. At that time, I knew I was wrong."

The ballpoint pen was spinning quickly in Cheng Bin's hand: "Where are these books now?"

"..."

"where is it?"

"I burned it."

"How did it burn?"

"In the open space of the school, a fire was lit with a lighter."

"What about the rest of the burning?"

"The ashes were wrapped in newspaper and thrown into the school bin."

"You are destroying evidence!"

"No, I... I'm just afraid that it will hurt others again."

"Is that so?"

"Yes."

"When was the first poisoning?"

"..."

"I'll ask again, when is it?"

"At the beginning of this semester, there was only one time in total."

Cheng Bin loosened his fingers, and the ballpoint pen fell on the table with a snap. He leaned back, and the chair creaked: "If I remember correctly, Li Qianqian felt unwell at the end of last semester. It was comfortable, and she lost a lot of hair at that time. The comb at home was never cleaned, and there were still many hairs on it that fell out before school started. When people are poisoned, toxins can also be detected in the hair, you know that? "

Yang Ying's eyeballs began to tremble again, and when she couldn't control the trembling, she patted the table and stood up: "I have only poisoned once, so don't talk nonsense without evidence, I will sue you for framing!" Then she stopped, He looked at Cheng Bin in surprise, as if he didn't expect to lose control like this.Then she sat back like a deflated ball, and resumed her cowardly look: "She is doing well now, if she is willing to withdraw the lawsuit, will I still go to jail?"

Cheng Bin glanced at her in surprise, and replied, "You should consult your lawyer for this question."

Later, Yang Ying did not fully plead guilty, as long as there is no solid evidence, she insisted that she did not do it.So far, she has only admitted that she poisoned one of Li Qianqian's books at the beginning of this semester, and denied that she knew she had the habit of licking her fingers while flipping through books.

Yang Ying's parents arrived early the next morning, unkempt and dusty, apparently just arrived from the train station.They are all honest and ordinary people, apart from saying that it is impossible for their daughter to be poisoned, they just beg for mercy everywhere.Cheng Bin privately gave Xiao Mi 200 yuan, asked her to take them to a meal, and found a small hotel nearby for them to stay.

After meeting her parents, Yang Ying finally cried like a child.Her parents thought of many reasons for her, such as being framed by her classmates, being jealous by her roommates, accidentally hitting bad luck, etc... They also comforted her, as long as she didn't do it, nothing would happen, they would Find a lawyer for her, a teacher for her, and a city leader for her. At worst, they will live in the police station. If the matter is not resolved, they will not leave for a day.This makes the police very helpless, it is not easy to rush, and it is impossible to stay.

The two old men wore simple and shabby clothes, and they didn't bring an extra set of clothes when they came to the city. They wore the same outfit every day.Father Yang got tired of squatting in front of the police station, so he took off his broken leather shoes in the corridor and pinched his feet. The sour smell frightened the policewomen, and they fled inside holding their noses.

Whoever arrests them is responsible. A group of female policemen went to the second team to jointly protest. Yu Renjie had no choice but to go to a nearby supermarket to buy a dozen underwear and socks and send them there.When Yu Renjie came back from Father Yang's place, Yu Renjie almost got asthmatic, his face turned pale for a while before recovering.

Not knowing whether she was influenced by her parents, Yang Ying also began to insist that she was innocent. She overturned her previous confession, claiming that she pleaded guilty indiscriminately because she was frightened by the vicious police.She changed her words and said that in fact she did not poison, but hid the poison in the dormitory. Before she had time to commit the crime, Li Qianqian fell ill.In any case, the toxins in Li Qianqian's body have nothing to do with her.

But Cheng Bin didn't blackmail her. The forensic doctor had already collected her hair from Li Qianqian's wooden comb, and detected thallium in it, proving that Li Qianqian had been poisoned three months ago.Afterwards, the police collected Yang Ying's blood, and found a trace amount of thallium in Yang Ying's body that exceeded the standard. Although it did not cause obvious harm to the human body, it was significantly higher than the normal content of this element in the average human body.The police suspect that she inhaled poisonous gas while burning the books.Even if you wear a mask, it can't be completely sealed, let alone protect all your skin.

A few days later, a group of students came to the gate of the police station. The seven and eight students were all Li Qianqian's classmates. Surprisingly, they did not come to defend Li Qianqian, but Yang Ying.

Yu Renjie brought them into a conference room, served tea and snacks, and waited on them well.When their emotions were no longer agitated, he explained to them the process of the police handling the case, and promised to deal with the case fairly, hoping to dispel their concerns.But the students were not interested in proving Yang Ying's innocence, but were eager to explain that Yang Ying had a reason for doing so.

The students were talking all over the place, causing Yu Renjie's brain to hurt. He turned around and went out, and returned with a loudspeaker.There are several buttons on the speaker, he doesn’t know how to use them, just press them casually, and the song “Fifteenth Moon” mixed with the sound of metal friction like a bellows comes from it, and the music from garbage trucks passing by on the road when I was a child Same, very harsh.Yu Renjie groped for a while, stopped the music, and found the correct speaker button.He pulled the horn closer to his mouth: "Hey, hey, hey, can you hear me? It's too messy for you to talk together, why don't you find a representative first, let's sit down and talk."

Students, you look at me, I look at you, and finally Yang Ying's roommate, He Jing, stood up.This day she was still wearing a pair of ripped jeans with a pair of white sneakers underneath, and pulled her oblique bangs to the side. She said: "I know the situation best, let me tell you. You have seen mine, I It's called He Jing."

He Jing said that no one would like to share a room with Li Qianqian.In fact, her sleep disorder is not just as simple as snoring or talking in sleep, but like an active volcano that erupts every day, a minefield that is bound to be detonated, and a series of firecrackers that ignite at any point-except for the deaf, no one can help her. put up with her.

In He Jing's mouth, Li Qianqian who fell asleep was simply a demon, never resting for a moment.She not only snores and kicks the bed boards, but also quarrels with others in her dreams from time to time. She often yells hysterically while kicking the bed boards.That state is completely abnormal, just like going crazy, it's creepy.

"Every time she barked, we all had to wake up, all scared! But even if she wasn't making a lot of noise, the snoring alone was unbearable, I've never seen The snoring is so loud, my dad is much fatter than her, and it’s not like this. But we have all developed the habit. When she screams at night, we wake up and chat with each other for a while. Anyway, we can’t fall asleep when we hear her snore. "He Jing said lightly: "Later we made an agreement with her that we would wake her up when she made a fuss, otherwise we would not be able to sleep at all - only when she was awake, we could fall asleep. At first We lived in the same dormitory with her. We had to wake up at least seven or eight times a night. After getting used to it, we only woke up three or four times. Of course, no matter how many times we woke up, we couldn’t open our eyes during class the next day. , I will really faint in class, from opening my eyes to falling asleep, it only takes a second, and there is no transition in the middle."

Yu Renjie nodded to her: "Sounds like a toss, I heard that you went to the Academic Affairs Office to make a fuss, and finally decided to keep her in the dormitory, is that so?"

He Jing chuckled, then rolled her eyes: "Who said it? Was it our counselor?"

"It seems that the actual situation is not like this, let's talk about what happened at that time."

"Then I have to tell you about the background at that time."

He Jing said that they expressed dissatisfaction with Li Qianqian's sleeping habits since they were young, but they expressed it in a more tactful manner because of face, but Li Qianqian couldn't understand what they meant, thinking that her sleep talk was very interesting.For example, when her roommates told her what she had talked in her sleep last night, not only did she not realize that she was causing trouble to everyone, but she also giggled there, taking it as a funny thing, and talking on the phone with her relatives and friends. To show off.What's more, for a period of time, she asked them every day with a smile, what kind of dreams did she talk about yesterday, and said that she wanted to go out to read a book in the future, and the name was "Li Qianqian's Dream Talks Complete Collection".

Later, the girls in the dormitory realized that they should be stricter with Li Qianqian. They held a dormitory meeting and told Li Qianqian directly about their difficulties. I turned it over.She promised her roommate during the meeting that every night she would go to bed every night, she would play with her mobile phone more, and then she would go to sleep after everyone fell asleep. This was her sacrifice and compromise, and it was also her self-righteous perfect solution.

But the night is long, no matter whether Li Qianqian sleeps half an hour later or an hour later, the essential problem is still not resolved in those more hours after she fell asleep.

"Later we recorded the sound for her, and recorded the snoring sound for a whole night. At that time, she finally turned her face and felt that we were targeting her together. On the weekend, she protested with us and went home to sleep by herself. But I don't know what happened. Be it her strengths or weaknesses, she changed back to her old self after a few days, with a playful smile on her face, refusing to go home on weekends, insisting on sleeping in the dormitory.” He Jing gritted her teeth when she said this, obviously feeling sorry for Li Qianqian. Very dissatisfied with the practice.

"She is a local, and she still sleeps at school on weekends?" Yu Renjie asked.

"In our dormitory, she is the only local. The locals rush home on weekends, but she likes to stay in the dormitory. She doesn't even give us two days of quiet time!"

"I can't sleep well every day, it's quite torturous, you continue."

"In Li Qianqian's point of view, we made a fuss over a molehill and didn't give her face, but we tried both soft and hard. The problem is that she didn't pay attention to this issue at all, and always thought we were joking. So we discussed it later and worked together. Going to the department to apply for a dormitory change, I hope Li Qianqian can move out."

"Speaking of which, I will interrupt again," Yu Renjie touched his nose and said, "Li Qianqian told me that at that time you proposed that as long as she can move out to sleep at night, it will not affect your contacts at other times, is that right?"

"Yes, that's right. To be honest, we didn't have much hatred or resentment towards her. We just wanted to sleep well. Although we often annoy her, as long as the sleep problem can be solved, those are trivial things .”

"How did it work out?"

"He Li, the counselor of our department, talked to us once."

The first time they proposed to change dormitories was during the first semester of their freshman year. They had a life counseling class that was taught by a psychological teacher from outside. Prepare.

Wang Xiaoqi consulted the teacher about Li Qianqian during the break, and the teacher suggested that Li Qianqian go to a psychological clinic, saying that her condition was caused by a serious mental illness and she should be treated as soon as possible.At that time, Wang Xiaoqi told Li Qianqian about this matter, but Li Qianqian didn't make any response, she just slapped her and got away.And when the three people in the dormitory united to ask her to move out of the dormitory, she promised in front of the counselor that she would see a psychiatrist as soon as possible and try her best to cure her illness, but she still hoped to continue living with everyone during the treatment period. Together.At this time, the hearts of the three girls softened, and they agreed to the request.

Li Qianqian's going to receive psychological treatment was the solution to their dormitory-moving incident. After that, the three girls enthusiastically helped to inquire about excellent psychological counselors, hoping to provide her with some help.

"Isn't that good, did the treatment work later?" Yu Renjie asked.

But He Jing only replied with two words: "Hehe."
