Qin Yueying has a total of three dormitory roommates, Feng Lili has a bad relationship with her, Fan Wei has an average relationship with her, and Qiao Xiaohong has a good relationship with her. The three girls only remembered that Qin Yueying brought the water cup when she went to the drawing classroom, but no one knew where the water cup went later.

The drawing classroom is located on the sixth floor of the school teaching building, and there are eleven drawing classrooms on the same floor, equipped with drawing tools such as drawing tables, drawing boards, and T-rulers. The front and back doors of the classroom are open, and anyone can enter and exit, making it even more difficult to find the poisoner.

Who the hell is it? Poisoning classmates so viciously?

The girls in the same dormitory are the most suspicious, because they can easily throw thallium salt into Qin Yueying's water cup, and Qin Yuejingying gets up early and washes, goes to the cafeteria for breakfast, and goes to the toilet...... There will always be times when you look away from the water glass, and it is very easy to poison when there is no one in the dormitory.

The classmates in the drawing classroom on the same floor were also suspicious, because Qin Yueying arrived at the classroom at 7:40 that day, felt unwell at 9 o'clock and went to the doctor, between 7:40 and 9:00, there were very few students in the classroom, everyone buried their heads in drawing, and did not pay attention to whether anyone else came in the classroom, nor did they pay attention to whether anyone approached Qin Yueying, let alone whether they had touched Qin Yueying's water cup.

Qin Yueying was poisoned too deeply, her cranial nerves were damaged, her intelligence regressed to the state of being six years old, and all that memory disappeared, and she couldn't provide any useful information at all.

As a result, the investigation of the case entered a state of stalemate.

After investigating all the classmates who had the opportunity to come into contact with Qin Yueying's water cup, Gao Guangqiang locked his eyes on Feng Lili. First, according to the reaction of the other two classmates in the same dormitory, Qin Yueying hadn't gotten up when they got up in the morning to wash, but they heard the sound of Feng Lili getting up and turning over the drawers; Second, when Qin Yueying left the dormitory with a water cup, she found that there was no water in the boiling water bottle, and Feng Lili rarely took the initiative to pour boiling water for her; Third, Feng Lili's boyfriend is a senior in the School of Chemical Engineering and has the opportunity to get thallium salt.

However, during the interrogation of Feng Lili, Gao Guangqiang felt very difficult.

I thought she was just a girl who didn't know the world, and she could break through her psychological defense line with a fright and deceit, so that she could tell the truth. Unexpectedly, Feng Lili's personality is unusually calm and calm, and she answers honestly, but she is excusing herself every word.

"Yes, I was the second to wake up that day, but I always wake up early. The alabaster I wiped my face was in the drawer, and it's normal to open the drawer, right? ”

"Uncle policeman, is it wrong to help others? In the same dormitory, although I can't get used to seeing Qin Yueying, but seeing that there is no water in her boiling water bottle, I can help her pour some water, which is not good? ”

"Alas, my boyfriend Song Zhiqing and I are from the same village, he studied very hard, we applied for a scholarship to the University of M together, one will be an architect and the other will be an engineer in the future, the future is bright, why do you want to do something illegal to ruin your future? Besides, if you can get thallium salt and you are a suspect, is it possible that all the students of the chemical engineering college next door are likely to be poisoned? Will someone pursue Qin Yueying and be rejected and killed in anger? ”

Because of the relative backwardness of medical testing technology in the 80s, it took five days from Qin Yueying being in a coma and being sent to the hospital to being found to be poisoned by thallium and calling the police, which was enough for the criminals to destroy all the evidence.

Even if all the evidence chain pointed to Feng Lili, because of insufficient evidence, the police could only let her go.

He Mingyu nodded: "Unless you find the water cup and find the fingerprints on the water cup, this is a hammer." ”

Zhu Feipeng added: "Even if there are fingerprints, it can only mean that Feng Lili has touched this water cup." As long as she doesn't admit it, she still can't be hammered to death. ”

"Thallium salt is colorless and odorless, and has good solubility, but there must always be a container before poisoning, right? Have you searched in Feng Lili's drawer? Are there any paper bags or other boxes with thallium salt residue? ”

Gao Guangqiang shook his head: "What you can think of now, we have thought of it." ”

Zhu Feipeng said hatefully: "It would be good if Zhao Xiangwan was involved at that time, let her interrogate Feng Lili, and she will definitely be able to pull out her fox tail." ”

Xu Songling reminded: "In the absence of conclusive evidence, the police cannot arbitrarily identify Feng Lili as the murderer." As criminal policemen, we must not have preconceived ideas. ”

Zhu Feipeng snorted unconvinced, and muttered in his heart: Obviously Feng Lili did it, who else but her? Jealous people have beautiful parents and good family backgrounds, and they have found a rich boyfriend. Like her, who came to university by working hard, most of them can't get used to people like Qin Yueying who rely on their parents and men and can struggle for decades.

Zhao Xiangwan asked: "Is it possible that Feng Lili said the last sentence?" Is there a boy in the School of Chemical Engineering who pursues or has a crush on Qin Yueying? ”

Gao Guangqiang: "Yes, yes. Qin Yueying is beautiful, and she is also one of the top ten singers on campus, and she is not small. Among the boys in the School of Chemical Engineering next door, there are many people who admire her. However, we investigated and did not leave the school on the day of the accident. ”

The trail is broken again.

Zhao Xiangwan asked again: "Is it possible to buy. Bad. Kill. Person? ”

Gao Guangqiang was obviously stunned for a moment.

Campus poisoning, most of them are disputes between classmates, out of jealousy, indignation and other psychological factors, how did it rise to buy. Bad. Kill. To the point of people?

Zhu Feipeng is from a professional class in the end, and his eyes lit up: "If you buy. Bad. Kill. People, then all the alibi evidence does not exist, and you need to start with the motive first. ”

"Yes!" Zhao Xiangwan encouraged Zhu Feipeng to continue to play with his eyes.

Zhao Xiangwan remembered that when he met Xu Qingxi at the Four Seasons Hotel, he once said in his heart: Zhou Jingrong is a smiling tiger, he likes to hurt people with secret arrows, be careful! The woman with a thin figure and a gloomy face left a very bad impression on Zhao Xiangwan.

Zhao Xiangwan highly suspected that the poisoning case was related to Zhou Jingrong, and although Zhou Jingrong could not poison himself, he could instruct Feng Lili to do it.

Zhu Feipeng rarely got Zhao Xiangwan's affirmation, and the whole person became excited, picked up a piece of chalk, wrote the word "motive" on the blackboard on the side, and said loudly: "If you want to say that the motive for killing is the strongest, it should be Zhou Jingrong." Her husband cheated on her and found a young and beautiful college student, her position was in jeopardy, and she bought it at this time. Bad. Kill. people, the possibilities are great. ”

Zhu Feipeng hung a bandage in his left hand, and drew a circle on the word motive with chalk in his right hand, leading out a line, and the words "Zhou Jingrong" were written on the other end of the line; Immediately starting from "Zhou Jingrong", draw another line, and write the words "Feng Lili" at the other end of the line.

"Is it possible that Zhou Jingrong contacted Feng Lili privately and paid for her to go abroad, on the condition that she was poisoned in Qin Yueying's water cup?"

Gao Guangqiang's face changed.

If this is the case, then there is a problem with the direction of the police from the beginning!

Zhou Jingrong's suspicion still exists, and he will not be innocent because of alibi.

Whether Feng Lili knows Zhou Jingrong, and whether she and her boyfriend won a scholarship from a foreign school at the same time or whether Zhou Jingrong helped them, these should be investigated.

Gao Guangqiang's inner heaviness is getting stronger and stronger. At the age of more than fifty, wrinkles have climbed up to the forehead, with the vicissitudes of the wind and clouds. He is about to retire age, and today he suddenly found that there was a problem with the old case that had been sealed, and he was on pins and needles.

Zhao Xiangwan raised his head, and his voice was very soft: "Officer Gao, your investigation back then was very detailed, and I benefited a lot from reviewing the case file. Now we want to reopen the investigation and don't know how to go through the process? ”

The appreciation and sincerity from the younger generations made Gao Guangqiang feel a lot more comfortable, and he glanced at Xu Songling. Xu Songling patted his chest: "I'm here to apply for a re-investigation of this case, and the serious case team will take over, how about it?" ”

Everyone responded in unison: "Yes!" ”

The group of serious cases was full of young people, and their high morale made Gao Guangqiang infected, and he stood up and said: "Let me also join the investigation of this case, I have the contact information of Qin Yueying's parents, and I am more familiar with the situation back then." ”

Xu Songling stretched out his hand at him and smiled heartily: "Lao Gao, welcome to join!" ”

After shaking hands, Gao Guangqiang stopped talking, hesitated for a long time before saying: "Actually, we also encountered a lot of resistance when we investigated. The reporter of the "Star City Legal Weekly" had been following the investigation process of the case, but received a warning halfway through the case not to pay attention to the case. The Yuan team, who was in charge of the case, was transferred to the provincial department, which was part of the reason why the case was later closed in a hurry. ”

A dark cloud flashed on Xu Songling's dark face: "I will be responsible for the restart of the old case this time, and I will definitely not give up halfway." ”

The older the rivers and lakes, the less courageous they are. Gao Guangqiang glanced at the high-spirited young man in the office, and reminded again: "Eight years have passed, things are wrong, and it is difficult to find evidence, and it is very difficult to solve this case." ”

Zhu Feipeng smiled: "It's not difficult, where can we use a group of serious cases!" ”

The Serious Crime Team officially reopened the campus poisoning case.

The first person Zhao Xiangwan visited was Qin Yueying.

In the past two years, Chengnan No. 3 Middle School has built several new dormitory buildings, and everyone is happy to move to a new house, but Qin Yueying's family still lives in the first batch of old dormitory buildings built in the sixties.

The foot of the wall was already mottled, and the creeper climbed up the gable, covering the wall of a six-story brick and concrete house, revealing only the wooden windows where paint had fallen.

There is a yard on the first floor, and some vegetables are planted in the yard, and the red bricks are paved with red bricks, and flourishing weeds emerge from the cracks.

Standing in front of the iron fence gate of the courtyard, Gao Guangqiang said in a strong voice: "Teacher Qin, Teacher Qin, are you at home?" ”

The balcony door was pushed open, and a man with white hair walked out, he bent his waist, saw Gao Guangqiang, and responded happily: "Eh, it's Officer Gao, it's coming." ”

There was a ding-ding-clang, the iron door opened, and Zhao Xiangwan saw the man's face clearly, and he didn't know why there was a sour feeling in his heart.

Qin Yueying's father, Qin Yizhong, has white hair from his temples to the top of his head, like snow, without a single black thread. A pair of wise and gentle eyes, with vertical and horizontal lines at the corners of the eyes, slightly squinted eyes when smiling, and more profound lines.

He was only fifty-five years old, but he looked to be in his sixties.

Gao Guangqiang took Zhao Xiangwan, He Mingyu, and Liu Liangju with him, Qin Yizhong saw the unfamiliar face beside him, and asked with a smile: "Officer Gao, why did you bring so many young people here today?" Is there a mission to bring new people? ”

"Come into the house and say, come into the house and say."

Gao Guangqiang handed the fruit he was carrying to Qin Yizhong, walked through the small courtyard with him, and walked into the bedroom through the balcony door.

The first floor is not well lit, and there is a strange smell of acid decay in the air. Zhao Xiangwan squinted after entering the room, and after adjusting to the change in light for a while, he looked at the furnishings in the room.

In the old house of the school, because the door of the first floor was directly opened to the courtyard, the door of the stairwell from the living room was sealed. The balcony room was converted into a living room. The old wooden sofa, wooden coffee table, and a small domestic Panda brand TV are on the TV cabinet, which is playing cartoons.

After eight years, things are not people, but Qin Yueying's family seems to have been stuck in yesterday's years.

On the couch sat an obese woman in pajamas, with short shaved hair and a blanket on her knees, watching TV with relish, even when a guest came over.

This woman is Qin Yueying?

In the photo on the case file, Qin Yueying has a slender figure, a slender swan neck, a beautiful melon seed face, and a pair of smart big eyes, which is as beautiful as the star on the movie poster.

But...... Now, she's completely ruined.

The sofa was occupied by Qin Yueying, Qin Yizhong took a few old chairs from the next room for everyone to sit down, and got up to serve tea and pour water, for fear of slacking off the guests.

His legs and knees seemed to be bent, and his movements were a little inflexible, Gao Guangqiang asked with concern: "Teacher Qin, your arthritis is not well?" Is there a dressing? The first floor is too damp and cold, so you should consider moving to a new dormitory this time. ”

Qin Yizhong shook his head: "I can't move, Yafen and I are too old to climb the building." Moon Shadow is like this, and there is no way to change places. ”

Zhao Xiangwan's eyes followed Gao Guangqiang's line of sight and looked at Qin Yueying's legs covered under the velvet blanket. Judging by the raised shape, the legs are as thin as hemp stalks. Thallium poisoning caused muscle atrophy, which had left her paralyzed in her lower limbs.

He Mingyu also noticed it, and turned his face and couldn't bear to look at it again.

This case is Gao Guangqiang's knot, he became friends with Qin Yizhong during the investigation, and he would come to visit every once in a while. This time, I brought Zhao Xiangwan and the three over, and I am familiar with it.

Gao Guangqiang briefly introduced Zhao Xiangwan and them, explaining his intentions: "Mr. Qin, the city bureau plans to restart the old case, so come over to understand the situation, see if there are any omissions, and strive to bring the real culprit to justice." ”

After so many years, I thought that I had sunk unjustly to the bottom of the sea, but I didn't expect that the poisoning case could be re-investigated, Qin Yizhong stood up excitedly, with tears in his eyes, his lips trembled, and he grabbed Gao Guangqiang's hand: "Thank you, thank you!" Thank you for keeping this case in mind and thinking about avenging our Moon Shadow. ”

Chapter 37: The Water Cup

◎Where's the pink drinking glass? ◎

Qin Yizhong turned his head to the bedroom door and shouted, "Yafen, Yafen come quickly, the case of Moon Shadow has begun to investigate again." ”

A kind, white-haired woman came out of the next room, wearing glasses, holding a pen in her hand and a little ink on her fingertips, and asked incredulously, "What did you say?" ”

The woman is Qin Yueying's mother, Teacher Li Yafen. She had retired, had taken on some translation work to support her family, and was busy working in the next room and did not come out to greet customers. Hearing Qin Yizhong's shout, he couldn't hide the excitement in his heart, he couldn't put down the pen, and hurriedly came over to ask.

Qin Yizhong praised Gao Guangqiang repeatedly: "Fortunately, there is a good policeman like Officer Gao, after so many years, I still remember my family Moon Shadow, and our case has finally seen the light of day again." ”

Gao Guangqiang was ashamed of this, and hurriedly explained: "It's not my credit, this matter is really thanks to the young people in the serious case." It was they who felt that there was something strange about the case, so they re-investigated. ”

As for why the old case aroused the interest of the serious case group, Gao Guangqiang did not ask, no matter what the reason is, as long as someone can pay attention and work hard to find out the real culprit, even if he retires in the future, he can feel at ease, right?

Li Yafen and Qin Yizhong looked at Zhao Xiangwan, Liu Liangju, and He Mingyu at the same time, with tears in their eyes, they didn't know what to say, but kept repeating: "Thank you, thank you." You're good people, you're good people......"

Such a pair of simple and responsible intellectuals, because their daughter is in a bleak night, and they have to worry about her when they are over half a hundred years old, and anyone who sees it will be sad.

Zhao Xiangwan originally just wanted to pull Xu Juncai's pigtails, but he didn't expect to turn over an old unsolved case.

When I read the file, I felt angry, but now I saw with my own eyes that this family had fallen because of this case, and I saw Qin Yueying fall into this stupid and paralyzed situation, and this anger turned into a strong sense of responsibility.

We must find out the real culprit and give Qin Yueying justice!

Liu Liangju is one of the older members of the serious crime team, married for three years, and his daughter is now one and a half years old, which is the time to be lively and cute. Every time he came home after work, his daughter threw her arms around his neck and called her father sweetly, which was the happiest moment of his life. Now I see this pair of parents who have become gray-haired because of the murder of their daughter, and the fire of justice is burning in their chests.

Regardless of the fact that it was Gao Guangqiang leading the team this time, Liu Liangju stood up and said loudly: "Don't worry, we will definitely do our duty and find out the murderer!" ”

He Mingyu also promised: "Yes, we will work hard." She turned her head a little uncertainly, wanting to get strength from Zhao Xiangwan, "Right?" ”

Zhao Xiangwan nodded heavily: "Yes!" ”

Qin Yizhong and Li Yafen saw the three young men in civilian clothes, and the tears that had been choking in their eyes slid down their cheeks.

Li Yafen turned around and walked out of the living room, and when she came back, the pen had been put down and her hands were cleaned. She held He Mingyu and Zhao Xiangwan's hands left and right, and said softly: "You just do your best, as for the result...... Auntie doesn't force it. I'm tired of running around with your police comrades, and I'm uneasy. ”

Her palms are warm and soft, with a thick callus on the side of her middle finger, which is a pair of intellectual hands. stood on the podium for a lifetime, but was forced to retire early because her daughter needed to be taken care of, Li Yafen's heart was both reluctant and helpless.
