Criminal Investigation Notes

When Song Wen and Lu Siyu arrived at the first people's Hospital of Nancheng City, it was already 10:30 in the morning. Today is Sunday, the outpatient department is not open, only the inpatient department and emergency department are overcrowded. After waiting for the elevator for several minutes, they crowded up the building with a group of uncles and aunts. The elevator climbed like a snail, but it still stopped on every floor.

It took a few minutes to get to the 12th floor. This is the critical ward of Nancheng No.1 Hospital. It does not belong to any specialty. Instead, it gathers experts from various departments and receives some comprehensive critical patients.

When two people came up, Song Wen saw Lin xiuran standing outside the ICU and hurried over: "what's the situation now?"

"Guo Zhen entered the oxygen chamber in the morning, and is still observing in the ICU, but has not woken up. Lin wanwan was not poisoned deeply. After vomiting and gastric lavage, he was undergoing infusion. He was transferred to the ward here for observation. " Speaking of this, Lin xiuran also pointed to a middle-aged woman sitting on one side, "this is Guo's mother."

Song Wen turned to see that it was a middle-aged woman in her forties. She looked simple and plump. Beside her was an old but clean schoolbag. Her eyelids were swollen and she had obviously cried several times. She just sat in the chair at the door, not knowing what she was thinking.

Song Wen looked at the quiet and full of all kinds of instruments in the ICU. There was a nurse who was busy. He was afraid to see this kind of separation. He didn't prepare to say hello. He turned to Lin xiuran and said, "have you asked?"

Lin xiuran said in a low voice: "after a few words, Guo Zhen's father is not in good health, so she is the only one to come here this time. She is an only daughter. She is a middle-aged person. She thought her daughter would be able to support the family after graduation, but now It's a big blow. She didn't know much about Guo Zhen's school life. She only said that her daughter never let her worry. The people from the school have been accompanying me all the time. Now I'm going downstairs to do some shopping. "

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

Lin xiuran said, "the school has made arrangements."

"Is anyone watching here?"

"There are people from the school who are here for 24 hours."

One side of the Lu Si language asked: "Lin wanwan's family did not come?"

"Well, the people from the school were still complaining. After the notice was sent, they asked what to do with the medical expenses. When the school said that they would pay in full for the time being, they asked about the situation. They heard that there was no life danger, so no one came here." Lin xiuran obviously hasn't seen such a parent. Which child is not the heart of his parents? When something happened to the child, the parents were crying for help, but this family It's cold enough.

Song Wen said: "it's not surprising. I read the information about Lin wanwan. She and her father have different surnames. It should be a reorganization of the family. The family relationship is not very good. The mother later gave birth to a son, so the daughter may be ignored." Speaking of this, he looked at Guo's mother again. The woman sat there, and Shengsheng regarded herself as a sculpture. Song Wen was a little frightened. He didn't take the initiative to say hello. Instead, he said, "let's go and see Lin wanwan."

Lin xiuran looked at his watch: "I'm about to withdraw. I've already said hello to the doctor in charge. We'll be informed if there's a situation. 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 arrived at the door of 1205 according to the room number. Compared with the rescue area, it was much quieter here. The door was half closed. He pushed the door in without any resistance.

There was a girl lying on the bed who was infusing fluid. She was awake. As soon as she saw someone coming in, she turned her head and looked at it. It was a girl in her twenties. She looked smart and beautiful. Her eyes were not big. Her black eyes occupied a large place in her eyes. Her hair was soft and gentle. She looked like a small animal. At this time, she was wearing a white patient's uniform, trapped in a white sheet, weak, frightened and helpless.

Song Wen thinks of her conversation with Bai Xiaoxiao, and her metaphor can't be more appropriate.

Because she is still in the observation period, Lin wanwan's body is connected with some things to test ECG and pulse blood pressure. Her pale lips are tightly pursed, and her eyes are somewhat alert.

Song Wen pulled the chair beside the bed and sat down. He showed his police card and reported to his family: "Hello, I'm a criminal policeman in charge of this case in 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 it?"

Lin Wan Wan was half up, his eyes twinkled, and he did not open his mouth.

Lu Siyu stood aside and took out his notebook and pen for recording. 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 accentuated the word "killer" a little.

Lin wanwan's eyes moved, and then he recalled: "last night I was just about to go to bed when Dong Fang suddenly said that she had a stomachache, and then she vomited. Guo said that she would go to have a look. She had just helped her out of bed when Dong Fang fell to the ground. At that time, waiting horse Aijing fell off the bed. There was a loud noise. Guo fan was there to comfort them. I wanted to help. I also climbed down. As soon as I got out of bed, I felt unable to breathe. There were flowers in front of me. "

"Later, I heard someone struggling in the dark, as if something had happened. Then Guo Zhen ran out by himself. My mobile phone was out of power and wanted to call 120. At that time, I remembered that I had learned Guo's mobile phone password by chance, so I used her mobile phone to call 120."Her description is a bit messy, but it also explains why Guo's mobile phone has her fingerprints. Speaking of this, Lin wanwan raised his head timidly and asked, "are Dong Fang and Ma Aijing dead? What about Guo Zhen? What's the matter with her? "

Song Wen did not answer her: "you are poisoned, what impression do you have of poisoning?"

Lin wanwan looked pale and shook his head: "I I don't know. I don't even know why I'm here. Yesterday's experience is like a nightmare. I have a headache when I think about it now. "

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

"Chocolate, we ate the chocolate Guo bought..." Lin wanwan's voice was a little shaky, "I I know that they have been bullying Guo Fen. When they are there, I dare not talk to her. When they are not, I can comfort and help her. A few days ago, Guo Zhen suddenly said that she did not want to live. 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 very happy. She asked me to give her advice on how to ease the dormitory relationship. I also helped her find a way. Then she bought a box of chocolates that Dong Fang liked to eat, apologized to them in a low voice, and then everyone was very happy to share the chocolate... "

Lin wanwan said here and looked up in horror: "the poison is not under the chocolate, right? Did she want us all to die with her? " With the emotional excitement up, her eyes overflow tears, a pair of cover mouth want to vomit appearance, one side of the instrument also suddenly lights up the red light.

Song Wen ignored those, stood up and stepped forward to force him to ask, "where do you think Guo's poison in chocolate comes from?"

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

The door was suddenly opened. Before Song Wen and Lu Si Yu could react, a woman doctor and two nurses rushed in from outside. When Lin wanwan's condition became a little stable, the woman doctor with a ponytail turned her head and frowned at Song Wen and Lu Siyu: "who are you? Is the patient's family member? "

Her tone was a little bad. Song Wen felt that it was not good to argue about these things here, so she took a few steps to get out of the ward, and showed the police officer's testimony: "this patient is related to a poisoning case. I'm a criminal police officer of Nancheng Municipal Bureau, and I'm conducting a routine inquiry..."

The woman doctor was a head shorter than Song Wen. She looked like a little girl. She took the police officer's card and looked at it again and again. She seemed to suspect that the thing was fake. She looked at it carefully for several times before returning it to Song Wen.

Just when Song Wen thought he was going to give them a green light, the female doctor looked up and said, "do you think this hospital is a police station? She is now a patient. The hospital is responsible for the patient's safety. She has just come out of danger and now needs observation and rest. Are you responsible for any problems? " When she said that, her face sank and waved her hand, "please don't disturb our work and rest of other patients. Tomorrow, when she can be discharged from hospital, you can have a trial at will."

Song Wen didn't argue with her. He didn't know which Doctor Lin xiuran was talking to. It was meaningless to make conflicts again at this time. So he calmly retreated: "OK, this is the hospital. The doctors are the biggest. We will consider asking after the patient's condition becomes more stable. I hope you will cooperate with us at that time."

The woman doctor was said by him, but she felt that she was a bit in the wrong, and her tone softened down: "well When she's better, we'll communicate. "

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

Song Wenxin has a good sense: "do you also feel that Lin wanwan is lying?"

Lu Si Yu 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 knows nothing about this matter, she should be very angry. She should be anxious to question you first, and should be right in her mind. But her attitude is obviously wrong. "

Song Wen nodded his head and said, "yes, Lin wanwan was extremely calm when we entered. Her answers were in accordance with the order we asked. She answered some questions very quickly and was a little urgent. It seemed that she had already prepared to speak and was eager to tell those to the police. When she said she didn't know about the poison in the chocolate, her head turned to the window and her eyes fluttered. It was a very obvious evasion. She knew about the poison at least

After being forced by Song Wen for several times, Lu Siyu finally saw something and was no longer depressed. Their reasoning angles were different, but their conclusions were the same. After only a few minutes' communication, they were sure that Lin wanwan might have lied.

Song Wen thought about it and said, "but I still can't figure it out. Where did the poison come from?"

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

He felt that the poison was not from the chemical laboratory. Several people did not know the students of chemistry department. Moreover, the purity of the poison they used was obviously not as high as that of the laboratory. Otherwise, four people would have been killed and would not have given them so much reaction time.

"I have an idea about the source of poison." Lu Siyu took out Lin wanwan's mobile phone from his pocket. This time, he took the mobile phone with him. "The shops where Lin wanwan works are very miscellaneous, and also spread all over all walks of life, coffee shops and fast food restaurants. It's not a long time for each of them to work. She should be here recently."With these words, Lu Si language opened the nearest search place on the google map of Lin wanwan mobile phone. Her mobile phone is too clean, clean as if deliberately cleaned, but these not commonly used software, but exposed some small information.

"New home Square?" Song Wen took a look at the mobile phone, the final search point is here.

"No, she was supposed to be near the square, just searching for a landmark nearby." Xinjiadi is a comprehensive square in Nancheng. It is not too near or far away from Nancheng University. There are some small shops nearby.

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

"If I'm right, it's probably a pet store, and it's not a very formal pet store." Then Lu Si's thin lips opened and said a guess, "sodium cyanate and succinylmenine, which is a commonly used formula for poisonous dog needles, may be the source of the poison."

Song Wen suddenly remembered Fu Linjiang's apron when he searched the dormitory and pointed to a small shop next to xinjiadi Square: "Xinxin pet store!" When the case arrived here, I just felt that I was walking into a dead end, but when I turned around, the front suddenly opened up.
