Criminal Investigation Files

It was already 1:10 am when Song Wen and Lu Siyu arrived at Nancheng No.30 People's Hospital. Today is Sunday, and the outpatient department is closed. Only the inpatient department and the emergency department are overcrowded.Lu Siyu waited for several minutes for the elevator before squeezing upstairs with a group of elders and aunts. The elevator climbed like a snail, and it still had to stop on every floor.

It took another few minutes to reach the twelfth floor. This is the critically ill ward of Nancheng No. [-] Hospital. It does not belong to any specialty, but gathers experts from various departments, and all of them receive comprehensive critically ill patients.

Song Wen went up the stairs faster, and when he reached the twelfth floor, he saw Lin Xiuran standing outside the ICU, and hurried over: "How is the situation now?"

"Guo Hua went into the oxygen chamber in the morning, and is still under observation in the ICU. She hasn't woken up yet. Lin Wanwan's poisoning is not serious. After inducing vomiting and gastric lavage, she is undergoing infusion, so she was transferred to the ward here for observation." Having said that, Lin Xiuran again Pointing to a middle-aged woman sitting beside, "This is Guo Hua's mother."

Song Wen turned his head to look, it was a middle-aged woman in her 40s, she looked plainly dressed, she was a little fat, and there was an old but clean schoolbag beside her.Her eyelids were swollen, she had obviously cried a few times, she just sat blankly on the chair by the door, not knowing what she was thinking.

Song Wen looked at the quiet ICU full of various instruments. There was a busy nurse inside. He was most afraid of seeing this kind of life and death. He was not ready to go over to say hello, so he turned to Lin Xiuran and said, "Have you asked?" ?”

Lin Xiuran whispered: "We chatted for a while, Guo Wei's father is not in good health, so she is the only one here this time, Guo Wei is the only daughter, she is considered middle-aged, and originally thought that her daughter would be able to subsidize the family after graduation , but now... it's a big blow. She doesn't know much about Guo Wei's time at school, she just said that her daughter never made her worry. Just now, people from the school have been accompanying her, and now she's going downstairs to buy things went."

Song Wen nodded: "Is the family's accommodation arranged?"

Lin Xiuran said: "The school has made arrangements."

"Is anyone here watching?"

"Someone from the school is here to accompany you 24 hours a day."

Lu Siyu on the side asked, "Did Lin Wanwan's family come?"

"Well, the people from the school were still complaining just now. After the notification came, they asked what to do with the medical expenses. When the school said that they would pay the full amount in advance for the time being, they asked about the situation. They heard that there was no danger to their lives, so no one came. " Lin Xiuran obviously has never seen this kind of parents, which of the children nowadays is not the darling of their parents?When something happened to the child, the parents were crying and wanting to come over, but this family...is so indifferent.

Song Wendao: "It's not surprising. I read Lin Wanwan's information. She has a different surname from her father. It should be a reorganized family. The family relationship is not very good. The mother later gave birth to a son, so this daughter may have been left out in the cold. "Here, he looked at Guo Wei's mother again. The woman was sitting there, treating herself like a sculpture, motionless. Song Wen was a little scared, and didn't take the initiative to say hello. Instead, he said, "We Go and see how Lin Wanwan is doing."

Lin Xiuran looked at his watch: "I'm about to leave too. I've already called the doctor in charge. We'll be notified if something happens. Lin Wanwan is in room 1205, and she's the only one in the double room for the time being."

Song Wen and Lu Siyu came to the door of 1205 according to the room number. Compared with the rescue area, it was much quieter here, and the door was ajar. He pushed the door and entered without any resistance.

There was a girl lying on the bed who was getting an infusion. She was awake, and when she saw someone coming in, she turned her head to look at it. It was a girl in her 20s. She looked well-behaved and beautiful. Her eyes were small, with black eyeballs in their sockets. It occupies a large position, the hair is soft and docile, it looks like a small animal.At this time, she was wearing a white hospital gown, sunken deep in a white sheet, weak, frightened and helpless.

Song Wen remembered talking with Bai Xiaoxiao, her metaphor couldn't be more appropriate.

Because she was still in the observation period, Lin Wanwan was attached to something to test the electrocardiogram and pulse and blood pressure. Her pale lips were tightly pursed, and her eyes were a little wary.

Song Wen pulled up the visiting chair beside the bed and sat down. He showed his police officer ID and reported his family name: "Hello, I am the criminal policeman in charge of this case from the Nancheng Public Security Bureau. There was a poisoning case in your dormitory last night. , as a party to this case, can you tell me something about the situation at that time?"

Lin Wanwan stood up halfway, her eyes flickered, but she didn't speak.

Lu Siyu stood aside and took out his notebook and pen to take notes. Song Wen continued to ask in a low voice, "I know you don't want to recall, but this information is very important for us to find the murderer." He said the word "murderer" Time to add a touch of tone.

Lin Wanwan's eyes moved, and then she recalled: "Last night... I was about to go to bed, Dong Fang suddenly said that she had a stomachache, and then she vomited, Guo Wei said she would go and see, just helped her Dong Fang fell to the ground as soon as she got out of bed. At this time, Ma Aijing fell off the bed with a loud noise. Guo Wei was there to comfort them. I wanted to help, so I climbed down too. It's flowers."

"Later I heard someone struggling in the dark, as if something had happened, and then Guo Hua ran out by herself. My phone ran out of battery, and I wanted to call 120. At that time, I remembered that I had heard about Guo Hua by chance before. phone password, so I used her phone to call 120."

Her description was a bit messy and detailed, but it also explained why Guo Hua's phone had her fingerprints on it.Having said that, Lin Wanwan timidly raised her head and asked, "Are Dong Fang and Ma Aijing dead? Where is Guo Wei, how is she?"

Song Wen didn't answer her: "You were poisoned, what impression do you have of the poisoning?"

Lin Wanwan paled and shook her head: "I... I don't know, I don't even know why I'm here. Yesterday's experience was like a nightmare, and now I think about it and I get a headache."

"What did you eat before going to bed last night?" Song Wen asked again.

"Chocolate, we ate the chocolate Guo Hua bought..." Lin Wanwan's voice trembled a little, "I...I know they have been bullying Guo Hua, and I dare not talk to her when they are around. I can only comfort and help her when the time comes. A few days ago, Guo Wei suddenly said that she didn't want to live anymore. I comforted her for a long time, and then one day she said that she didn't want to continue the stalemate with Dong Fang and the others. I was quite happy , she asked me to help her with ideas on how to ease the relationship in the dormitory, and I also helped her find a way. Later, she bought a box of chocolates that Dong Fang liked to eat, apologized to them humbly, and then everyone happily shared Chocolate to eat..."

When Lin Wanwan said this, she raised her head in horror: "Could it be that the poison was put in the chocolate? Does Guo Wei want us all to die with her?" As her emotions became agitated, tears overflowed from the corners of her eyes , covering his mouth as if he wanted to vomit, and the red light of the instrument on the side suddenly lit up.

Song Wen ignored those, stood up and took a step forward and asked, "Where do you think the poison Guo Hua put in the chocolate came from?"

"I...I don't know..." Lin Wanwan's voice trembled.

The door was suddenly opened, and before Song Wen and Lu Siyu could react, a female doctor and two nurses rushed in from outside, and hurriedly began to check the equipment. The female doctor with ponytail turned her head and frowned at Song Wen and Lu Siyu: "Who are you? Are you the patient's family?"

Her tone was a bit unkind, Song Wen felt that it was not good to argue about this here, so he withdrew a few steps outside the ward, lit up the police officer and testified: "This patient is related to a poisoning case, I am from the Nancheng Bureau Interpol, conducting routine interrogation..."

The female doctor was a head shorter than Song Wen, and she looked like a little girl. She took the police officer's certificate suspiciously, looked at it repeatedly, as if suspecting that it was fake, and checked it carefully several times before returning it. To Song Wen.

Just when Song Wen thought he was going to give them the green light, the female doctor raised her head and said like a cannonball: "You treat this hospital as a police station? She is a patient now, and the hospital is responsible for the safety of the patient. She just escaped danger." , I need to observe and rest now. Are you responsible for something wrong?" As he spoke, his face sank, and he waved his hand, "Please don't disturb our work and other patients' rest, and you can interrogate her tomorrow when she is discharged from the hospital. "

Song Wen didn't argue with her, and he didn't know which doctor Lin Xiuran was talking to. It would be meaningless to argue at this time, so he calmly backed down a step: "Okay, this is a hospital, the doctor is the biggest, we will consider it." Wait until the patient's condition is further stabilized before making an inquiry, and I hope you will cooperate with our work then."

The female doctor felt that she was a bit wronged by what he said, and her tone eased: "Then... Let's communicate again when she is in better condition later."

When the doctor walked away, Lu Siyu bowed his head and said, "I think the information just now is enough... Now that there are new clues, it's time to investigate."

Song Wen had a tacit understanding: "You also feel that Lin Wanwan is lying?"

Lu Siyu nodded: "She has been awake since last night, and she should have thought about what happened last night several times in her heart. If she was a victim who didn't know about it, she should be brooding about it. Angry, I am anxious to question you first, and should be right in my heart. But her attitude is obviously wrong."

Song Wen nodded and answered his words: "That's right, just now Lin Wanwan was exceptionally calm when we entered, and her answers were all in the order we asked, and she answered some questions quickly, with a bit of urgency, like She had already prepared her words and was eager to tell the police. When she said she had no knowledge of the poison in the chocolate, she turned her head to the window and her eyes drifted. It was an obvious dodge. She at least knew about the poison."

After being forced by Song Wen several times, Lu Siyu finally saw something and stopped being bored. The two people's reasoning angles are different, but the conclusions are the same. After only a few minutes of communication just now, they are very sure that Lin Wanwan may Lied.

Song Wen thought for a while and said: "It's just that I still can't figure it out, where did the source of the poison come from?"

How does an ordinary college girl get highly poisonous without being known to others?

He felt that the poison did not flow out of the chemistry laboratory. Several of them did not know the students of the chemistry department, and the purity of the poison they used was obviously not as high as that of the laboratory. So much reaction time.

"I have an idea about the source of the poison." Lu Siyu took out Lin Wanwan's cell phone from his pocket as he spoke, and he took it with him when he came out this time. "The shop where Lin Wanwan works is very Miscellaneous, but also all walks of life, coffee shops, fast food restaurants, each of which does not take long, and the one she is most recently should be here."

While talking, Lu Siyu opened the nearest search location on the Baidu map of Lin Wanwan's mobile phone.Her phone was too clean, as if it had been cleaned on purpose, but these infrequently used software exposed some tiny information.

"Xinjiadi Square?" Song Wen took the phone and looked at it. The last search point was here.

"No, she should go to the place near the square. She just searched for a nearby iconic place." Xinjiadi is a comprehensive square in Nancheng, not too close or far from Nancheng University. Some small storefronts.

"Then what do you think her latest job should be?" Song Wen asked.

"If I'm not mistaken, it's probably a pet shop, and it's not a regular pet shop." Then Lu Siyu opened his thin lips lightly, and said a guess, "Sodium cyanide plus succinate, that's A commonly used formula for poisonous dog needles, perhaps the source of the poison comes from this."

Song Wen suddenly remembered the apron that Fu Linjiang found out when he was searching the dormitory, and pointed to a small shop next to Xinjiadi Square: "Xinxin Pet Shop!" The front of the turn is suddenly clear.
