Criminal Investigation Notes

When Song Wen and Lu Siyu arrived at the Nancheng First People's Hospital, it was already 10:30 in the morning. Today is Sunday, the outpatient clinic is closed, only the inpatient department and emergency department are overcrowded.Lu Siyu waited for the elevator for several minutes before squeezing upstairs with a group of grandparents. 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 critical ward of Nancheng No. 1 Hospital. It does not belong to any special department, but a collection of experts from various departments. It receives some comprehensive critically ill patients.

Song Wen walked up the stairs faster. When he reached the twelfth floor, he saw Lin Xiuran standing outside the ICU and hurriedly walked over: "How is the situation now?"

"Guo Wei entered the oxygen chamber in the morning and is still observing in the ICU. He has not woken up yet. Lin Wanwan was not deeply poisoned. After vomiting and gastric lavage, she was receiving fluids and transferred to the ward for observation." Having said that, Lin Xiuran again Pointing to a middle-aged woman sitting aside, "This is Guo Wei's mother."

Song Wen turned his head and looked at it. It was a middle-aged woman in her forties. She looked plainly dressed and slightly fat. Next to her there was a somewhat old but cleanly washed schoolbag.Her eyelids were swollen, she had obviously cried several times, and she just sat blankly on the chair at the door, not knowing what she was thinking.

Song Wen looked at the quiet ICU, which was full of various instruments. There was a nurse in it. He was most afraid of seeing this kind of life and death. He was not ready to go to say hello. He turned around and asked Lin Xiuran, "Have you asked? ?"

Lin Xiuran whispered: "Probably after a few conversations, Guo Wei's father is not in good health, so she was the only one who came here this time. Guo Wei is the only daughter. She is 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 at school, except that her daughter never made her worry. The people from the school have been accompanied just now, and now she is going downstairs to buy things. went."

Song Wen nodded: "Are the accommodation arrangements for the family members?"

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

"Is anyone staring here?"

"There is someone from the school, and I will be here for 24 hours."

Lu Siyu on the side asked: "Lin Wanwan's family didn't come?"

"Well, the people at the school were complaining just now. After the notice was passed, they asked what to do with the medical expenses. When the school said that it was temporarily paid in full, it asked about the situation. I heard that there was no life-threatening situation, so no one came here. "Lin Xiuran obviously hasn't seen this kind of parents. Which children are not the parents' hearts?When something happened to the child, the parents were crying to come over, but this house... is really indifferent.

Song Wendao: "It's not surprising. I read Lin Wanwan's information. She has a different surname from her father. She should have reorganized the family. The family relationship was not very good. Later, the mother gave birth to a son, so this daughter may have been left out. "Speaking of this, he looked at Guo Wei's mother again. The woman was sitting there, thinking of herself as a sculpture, motionless, Song Wen was a little bit shocked, did not take the initiative to say hello, and turned instead, "We Go and see Lin Wanwan's situation."

Lin Xiuran looked at the watch: "I am about to withdraw. I have already greeted the doctor in charge. We will be notified if there is a situation. Lin Wanwan is in room 1205, and she is the only one in the double room for the time being."

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

There was a girl lying on the bed who was receiving an infusion. She was awake. She turned her head to look when she saw someone coming in. She was a girl in her twenties. She looked well-behaved and beautiful. Her eyes were small and black eyes The eye socket occupies a large space, and the hair is soft and gentle, looking like a small animal.At this time she was wearing a white hospital gown, sunken in a white bed sheet, weak and helpless.

Song Wen remembered the conversation with Bai Xiaoxiao, her analogy couldn't be more appropriate.

Because it was still under observation, Lin Wanwan's body was attached to something to test the ECG, pulse and blood pressure, her pale lips were tightly pressed, her eyes a little wary.

Song Wen pulled the chair next to the bed used for visits, and showed a police officer ID to report to his home: "Hello, I am the criminal police officer in charge of this case in Nancheng Public Security Bureau. There was a poisonous murder in your dormitory last night. , As a party to this case, can you tell me something about the situation at that time?"

Lin Wanwan half propped up, her eyes flickering, and she did not speak.

Lu Siyu stood aside and took out his notebook and pen to record. 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" At that time, a tone was emphasized.

Lin Wanwan's eyes moved, and then she recalled: "Last night...I was about to go to bed. Dong Fang suddenly said that her stomach hurts, and then she vomited. Guo Wei said she went to see and just helped her. When Dong Fang got out of bed, she fell to the ground. At this time, Ma Aijing fell off the bed. There was a loud noise. Guo Wei was there to comfort them. I wanted to help and climbed down. When I got out of bed, I couldn’t breathe. It's flowers."

"Later I heard someone struggling in the dark, as if something happened, and then Guo Wei ran out by himself. My phone ran out of power and wanted to call 120. At that time, I remembered that I had learned about Guo Wei by chance. I used her mobile phone to call 120."

Her description is a bit messy, but it also explains why Guo Wei has her fingerprints on his phone.Speaking of this, Lin Wanwan raised her head timidly and asked, "Are Dong Fang and Ma Aijing dead? What about Guo Wei, how is she?"

Song Wen did not answer her: "You are poisoned. What impression do you have about the poisoning?"

Lin Wanwan's face was pale and shook her head: "I...I don't know, I don't know why I am here. The experience yesterday was like a nightmare, and I have a headache when I think about it."

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

"Chocolate, we ate the chocolate that Guo Wei bought..." Lin Wanwan's voice was a little trembling, "I...I know they bully Guo Wei all the time. I don't dare to talk to her when they are there and wait until they are away. I was able to comfort and help her. 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. I was quite happy. She asked me to help her with an idea to see how to ease the dormitory relationship. I also helped her find a way. Later, she bought a box of Dong Fang's favorite chocolates, apologized to them in a low voice, and everyone happily divided Chocolate eat..."

When Lin Wanwan said this, she looked up with a little horror: "The poison is not in the chocolate, right? Guo Wei, does she want us to accompany her to death?" Tears overflowed from the corners of her eyes as she became emotionally excited. , He looked like he was covering his mouth and wanted to vomit, and the instrument on the side suddenly turned on a red light.

Song Wen ignored those and stood up and stepped forward and asked, "Where do you think the poison Guo Wei put in the chocolate comes from?"

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

The door was suddenly opened. 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. When Lin Wanwan's condition stabilized, she combed. The female doctor with a ponytail turned her head and frowned to look at Song Wen and Lu Siyu: "Who are you? Are you family members of the patient?"

Her tone was a bit bad. Song Wen felt it was not good to argue about these things here, so she took a few steps and withdrew to the outside of the ward. The officer Liangliang testified: "This patient is related to a drug case. I am from Nancheng City Bureau. Interpol, conducting routine questioning..."

The female doctor shortened Song Wen's head and looked like a little girl. She suspiciously took the police officer's card and looked at it repeatedly, as if she suspected that the thing was fake. She checked it carefully and returned it several times. 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 bullet: "You use this hospital as a police station? She is now a patient, and the patient's safety needs the hospital to take care of it. She just got out of danger. Now I need to observe and rest. Are you responsible for the problem?" He said, his face sank, and he waved his hand, "Please don't disturb our work and rest of other patients. Tomorrow when she can be discharged from the hospital, please feel free to try. "

Song Wen didn't argue with her, and he didn't know which doctor Lin Xiuran was greeting with. At this time, there is no point in having a conflict, so he calmly backed down: "Okay, this is the hospital. The doctor is the biggest. We will consider it. After the patient's condition becomes more stable, we will conduct inquiries. I hope you will cooperate with our work at that time."

The female doctor felt that she was a bit unreasonable when he said that, and her tone eased: "Then... wait for her to get better, let's communicate again."

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

Song Wenxin was very eloquent: "You also feel that Lin Wanwan is lying?"

Lu Siyu nodded: "She has been awake since last night. She should have considered the matter of last night several times in her heart. If she is a victim who has no knowledge of this matter, she should be brooding. Angry, I rush to question you first, and I should be thinking in my heart. But her attitude is obviously wrong."

Song Wen nodded and accepted his words: "Yes, Lin Wanwan was very calm just now when we entered. Her answers were in the order we asked. She answered some questions quickly, a little urgent, like She was ready to talk a long time ago and was eager to tell the police. When she said she didn’t know about the poison in the chocolate, she turned her head to the window and her eyes were erratic. That was an obvious dodge action, yes. She is at least aware of those poisons."

After being forced by Song Wen several times, Lu Siyu finally saw what he was no longer bored. The two people’s reasoning angles were different, but the conclusions were the same. After only a few minutes of communication, they were very sure that Lin Wanwan might Lied.

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

How can an ordinary college girl get poisonous without being known?

He felt that the poison did not flow out of the chemistry laboratory. Several people did not know the students in the chemistry department, and the purity of the poison they used was obviously not as high as that of the laboratory. Otherwise, four people were killed now and they would not be given to them. So much reaction time.

"About the source of the poison, I have an idea." Lu Siyu took out Lin Wanwan's mobile phone from his pocket while speaking. This time he took it with him when he came out. "The shop where Lin Wanwan works is very Miscellaneous, but also in all walks of life, coffee shops, fast food restaurants, each of them is not a long time, she should be here recently."

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

"Xinjiadi Plaza?" Song Wen took a look at the phone, and the last search point was here.

"No, she should go to a place near that square, but she just found a nearby landmark place to search." Xinjiadi is a comprehensive square in Nancheng, not too close or too far from Nancheng University. Some small storefronts.

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

"If I guessed correctly, it's probably a pet shop, and it's a pet shop that's not too formal." Then Lu Siyu's lips lightly opened, and he said a guess, "Cyan gasification sodium plus amber laudanine, that is A commonly used formula for poisonous dog shots may be the source of the poison."

Song Wen suddenly remembered the apron that Fu Linjiang had turned out when he searched the dormitory, and pointed his finger at a small shop next to Xinjiadi Plaza: "Xinxin Pet Shop!" The case came here, and I just thought it was a dead end. The front of the turn suddenly became clear.
