Early the next morning, when Song Wen stepped on to the city bureau, Lu Siyu was already sitting in his seat.

Song Wenzhi asked on the glass of the grid: "Have the inspection results of your car come out?"

Lu Siyu said: "The insurance company said that the paint is imported, it is a bit troublesome to repair, and the other is nothing major." He reached out and rubbed his eyes.

Song Wen saw that he was a little ill, and asked: "What? Didn't sleep well?"

Lu Siyu pointed to the stack of documents on the table: "I perfected the record last night, and I have been thinking about this case."

"Through so much, you didn't sleep much last night..." Song Wen picked it up and turned over. The copywriting on the table was handwritten and printed. Every page is neat and tidy, with clear handwriting. alter.That file was merged with Lin Xiuran's forensic report, the report on the physical evidence side, and the testimony of various witnesses, all put together into a thick pile. The case has been reported for more than one day, and the workload is not small.Thinking of the cases encountered in the past, they all need to be sorted out by themselves. Often the cases are solved and the information is not collected. Song Wen really feels that the past is unbearable to look back, and the reality is so happy.

"It's okay..." Lu Siyu was talking, his brows still frowned, a little hesitant to speak.

Song Wen felt that there was something in Lu Si's words: "Why, there are still doubts?"

Lu Siyu hesitated for a moment and said: "If the murderer is Guo Wei, there are some problems in the middle, I don't think I understand. If Guo Wei poisoned, she hates Dong Fang and Ma Aijing, then just retaliate against them directly. Why should I bring her best friend Lin Wanwan? Since she has already brought her, why did Lin Wanwan take the smallest dose? It’s not a big problem at all. Even if it wasn’t made by Lin Wanwan, she did yesterday. Speaking of panic, why did she lie? And why, as a murderer, why did Guo Hua run out to call for help?"

Song Wen lowered his head and turned over the dossier, and then turned his head to look at him. The questions Lu Siyu raised were also things he didn't understand.

In the last case, Lu Siyu was more passive. He was warned once. In this case, he was quite active in participating. As a leader, he couldn't fault it.

The two said this, but they saw Fu Linjiang coming in from the outside, his clothes were almost soaked in sweat, and the weather got hotter as it approached the middle of summer.

Song Wen asked, "Linjiang, did anyone bring it?"

Fu Linjiang took a bottle of mineral water and drank a few sips before he was able to answer him: "I just came back and almost had an accident in the morning. We went up to ask for someone, but the person was not in the ward."

Song Wen frowned: "Didn't the school say someone will be with you?"

"I just ran while the school people were asleep! The female teacher didn't know how to watch. At first, all of us looked down, but we couldn't find it. Then we found that she had climbed onto the rooftop and stood by the side. Go up, look down blankly. Really, maybe I jumped down later. I was so scared and sweaty, but it was fine."

Several people hurried to the interrogation room, and Lin Wanwan had already bowed her head and sat in it.

Under normal circumstances, her condition requires another two days of hospitalization for observation. However, due to the special circumstances, she was specially approved to be discharged early after the doctor’s examination. This time, the hospital was very cooperative, probably when she was out in the morning. The doctor was terrified and was anxious to throw this hot potato out.

At this time Lin Wanwan was sitting in the interrogation room, her hair that had grown to her collarbone loosened, her bangs were slightly long, covering her eyebrows, and she was very quiet.

Song Wendao: "Look at this emotion, it's not like jumping off the building." He looked at the time on the subpoena that Fu Linjiang filled out, clicked and said, "Go to the bureau to apply for forty-eight hours." Normal summons do not exceed ten. In two hours, special suspects can have a grace period of up to twenty-four hours, and if it is extended, forty-eight hours will be reported for special approval.

Song Wen had a hunch that today's interrogation must be a tough battle.

Zhu Xiao on the side said: "Wait...wait for me to change to a larger memory card." According to regulations, this kind of interrogation process must be videotaped, and there should be no interruption in the middle.

As soon as Song Wen walked into the interrogation room, Lin Wanwan looked up, her eyes flashed with tears: "Police officer, I'm sorry, I...lied yesterday..."

Song Wen still followed the process, asking about gender, age, ethnicity, and family situation first.Then he raised his eyes, his eyes sharp, "Lin Wanwan, are you committing a crime?"

"I...I'm guilty." Lin Wanwan said this, and several detectives in the observation room were a little surprised.Lu Siyu lowered his head, habitually bit the nail of his right thumb between his teeth, and continued to listen to Lin Wanwan.

Song Wen leaned forward with a serious expression: "Lin Wanwan, you know what the consequences will be if you lie."

"I understand." Lin Wanwan nodded.

"State your criminal process." Song Wen said solemnly.

"I...I know that there are poisons hidden in Guo Wei. I have seen her poison a few cats before." Lin Wanwan said, her fingers shrunk slightly together, "But I can't help it, those cats are just Gathered outside the back door of our dormitory not far away, I couldn’t rush away. When spring arrived, I was there all night and all night, saying that Guo Wei’s sleep was not good. Then she came up with an idea and wanted to come. An injection, drugged the cat."

When Song Wen came up without warning, Lin Wanwan confessed and asked her: "Where did the medicine come from."

"That medicine was bought by Guo Wei from the pet shop where we worked before... I used some before, and there is half of it left..."

"Later, you poisoned your classmate with that cat medicine?" Song Wen asked further.

"No...no...I lied, but I didn't lie about that matter." Lin Wanwan lowered her head, "I didn't expect that Guo Wei put the remaining poison in the chocolate."

Song Wen still asked without expression, "You repeat the detailed process of the whole thing."

Lin Wanwan thought about it for a while, and slowly said: "Half a month ago, Guo Wei had a conflict with Dong Fang and Ma Aijing..."

"Is it because of the interview call that I didn't receive?"

"No, not only because of that, there are also some secrets. Guo Wei has a quota for exchange students who can go abroad for a few months. According to the results, it should be Guo Wei. But when it comes to the end, the quota is changed to Ma Aijing. ."

This paragraph is something that everyone didn't know before. If you think about it carefully, it can be regarded as in line with their reasoning.

Lin Wanwan continued: "They had a conflict that day and Guo Wei was injured. I was in the dormitory at the time, but I was afraid of them and didn't dare to help her too much. Later, I accompanied her to the school hospital and prescribed some medicine. That night, she didn't dare to go back to the dormitory, and stayed in the next room with Bai Xiaoxiao.

Her small and gentle voice was in the entire interrogation room, and Song Wen did not interrupt her.

"The next day, I found Guo Wei again. At that time... Guo Wei said to me that she said she didn't want to live anymore and wanted to commit suicide. At that time, I had been comforting her all the time, and I didn't expect her to kill Nian. "

Speaking of this, Lin Wanwan paused, the little beast-like eyes lifted slightly, and looked at Song Wen, looking pitiful: "I only thought about it after being poisoned. It may be that Guo Yu used her from the pet shop. You should find out the medicine you got from here. Guo Wei bought a box of chocolates. Now she thinks that she should have secretly injected the medicine into the chocolate."

Song Wen squinted his eyes. This time, Guo Wei had the evidence of poisoning: "This is different from your previous testimony. Why did you lie yesterday."

Lin Wanwan's tears began to flow down her cheeks: "I was lying on the hospital bed yesterday and was thinking about this. When you came to ask, I wanted to tell you, but I was worried about the medicine. Pull me in. I was also very uncomfortable at the time. I didn't expect that as Guo Wei's best friend, she also wanted me to die together..."

"Then why are you telling us today?"

"After I lied, I have been particularly upset. When I stood on the rooftop this morning, I felt I was sorry to my classmates. If I had told Dong Fang and Ma Aijing about the murder of Guo Hua, they would be more alert. , If you don’t eat that chocolate, things won’t happen that night... and, I think you’ll find out about the cat medicine sooner or later..."

"You can retell the process the night before."

"The night before yesterday, Guo Wei apologized to Dong Fang and Ma Aijing in a low voice, took out the chocolate, let them choose first, and ate with them. I was not suspicious at the time, but thought the taste of chocolate was a bit strange, so I ate less A few mouthfuls."

"After that."

"Then...Dong Fang got poisoned first, and then Ma Aijing also got poisoned. I got out of bed to check and found that Guo Wei was lying on Ma Aijing's body. She was afraid of her yelling, so she covered her with a quilt... I went Pulling her, but she couldn't hold her at all until Ma Aijing didn't move anymore." Lin Wanwan said here, her lips trembled, as if she was reminiscing about the terrible night, "At this time, I and Guo Hua also had an attack. I asked her if she had given us the medicine, and she suddenly ran out on an impulse. My cell phone was dead. I found Guo Hua’s cell phone and called an emergency call."

"I'm sorry Dong Fang, I'm sorry Ma Aijing, I'm sorry Guo Wei, I'm guilty..." As he said, Lin Wanwan's shoulders kept shaking, seeming to be sincerely repenting.Lin Wanwan wiped away the tears with her hand, and finished speaking, she sat on the chair, relaxed slightly, and looked at Song Wen with red eyes.

Song Wen also looked at the girl in front of him, judging whether her words were true or false.

"Police officer, can I have some water?" Lin Wanwan asked.

Song Wen stood up and said, "Someone will come in with water later."

The facts of the case have reached this point. Lin Wanwan plugged all the loopholes in yesterday’s testimony, material evidence, confession, personal testimony...every clue pointed to Guo Wu, looking down at Lin Wanwan's calmness, but Song Wen suddenly Thinking of Lu Siyu’s evaluation of Lin Wanwan, she was either an extremely innocent passerby, or she was an extremely disguised criminal...

One bedroom, four girls, two victims, only one person can interrogate, the other is unconscious.

The case looks simple, and the answer is ready to come out, but is the truth really as Lin Wanwan said?Can they still know what happened that night?
