Cheng Han looked at the short-haired and slightly plump girl inside through the one-way mirror. To be honest, she doesn't like this girl's character of talking nonsense everywhere. Because before the results come out, it is really undesirable to talk nonsense behind the backs of classmates just to satisfy their own gossip psychology. To put it mildly, it is some villainous behavior.

Although she somewhat disagreed in her heart, she couldn't stop Bai Tingting in the end. I could only eat chocolate, stand in front of the one-way mirror, and carefully watch her every move, not missing every word she said.

"Uncle Policeman, we're meeting again."

As soon as Xiao Rongzheng and the others walked in, Bai Tingting, who was originally sitting in a chair, got up and greeted him warmly. That sleek and familiar look, if she wasn't still wearing a school uniform, she really wouldn't be able to see it at all, she was still a child in junior high school.

"Hello", Xiao Rongzheng smiled at her, and then asked, "It's dinner time, do you come here to talk to your family?" Don't let them worry. ”

"Hey, it's okay. My parents are busy with work and often travel on business, and I go back by myself, it doesn't matter. And I came here after eating at M Kee, so don't worry, I'm not hungry. ”

"That's fine, it's good if you're not hungry." Xiao Rongzheng sat down, stretched out his arm and touched Xie Wencong next to him, signaling him to start questioning.

Xie Wencong didn't talk much nonsense, and went straight to the point, "Little sister, let's talk, what is the matter with you looking for us?" ”

The little girl sat down, touched her nose, and said, "My classmate, Hu Sasa is gone at school today." Although the principal and the teachers told us not to talk nonsense, I felt that as her classmates, it was my duty to tell the police uncles everything I knew. It would be great if it could help. ”

"Hey, I didn't expect you to be quite conscious at your young age. Tell me for yourself, what do you know? ”

Bai Tingting looked at the three opposite generously, holding her chin, as if she was thinking about the events of the day.

"I'm Song Qi's tablemate, and she's been a little absent-minded all day today. Even when the teacher asked her to get up in class to answer questions, she didn't know anything. I remember that it was almost the end of the afternoon, and the two of us had made an appointment to go out for a bite to eat together and then come back to prepare for the evening rehearsal. But after she took her phone and sent a message, she said that she had something to do and couldn't come with me. ”

She mysteriously stretched out her hand and gestured with Xiao Rongzheng and the others, "At that time, her hand was like this covering her mobile phone screen to reply, although I couldn't see it really, but I will never be wrong about that word." At that time, Song Qi must have been sending a message to Hu Sasa. ”

Xie Wencong was a little puzzled, "Girl, someone sent a message, what did you come over to peek at?" ”

"What do you mean by me peeking, I care about whether they are good or not! Think about it, if there is any conflict between the two of them, I, an insider, might as well know who to help as soon as possible, and then prescribe the right medicine. Besides, the two of them are the people of the year in our school magazine, and my school magazine still points to the two of them to write manuscripts! ”

"So, you're equivalent to junior high school, well...... 'paparazzi'?" Xie Wencong pondered the words, for fear that his expression would be inaccurate.

Bai Tingting nodded in agreement, "So to speak, so, in our entire junior high school, there is almost no gossip that I don't know." Looking at her like this, it seems that she is not ashamed, but proud. Xie Wencong always felt that she had something to say, and he was afraid that she was not holding back a big move, so he talked little by little.

"Then let's talk about Hu Sasa first, what is there about her that we don't know yet?"

"Hu Sasa is a good person, he dances well, and his heart is also high. However, it was her birth that took her off her legs. Her sister desperately sent her to our international school, and to be honest, it was not easy. However, she is good, and spends all her living expenses on winning people's hearts. Either give this one a gift today, or invite that one to dinner tomorrow. Bought some fake brands and lied to us that her sister brought them back to her from abroad. ”

Bai Tingting snorted lightly to show her sneering attitude, and then said, "However, who can enter an international school does not have a little foundation, and has their own circle." Even if Hu Sasa tried her best to integrate into us, it was all in vain, and no one took her to play at all. On the contrary, gradually some people hate her high-profile behavior, and Song Qi is one of them. ”

"Don't look at her as a swan princess, in fact, what she is best at is to do one thing in front of her and one behind her back." As if she suddenly remembered something, Bai Tingting deliberately lowered her voice and leaned forward, trying to get closer to Xie Wencong and them.

"There are a lot of things that she doesn't do by herself and doesn't say it. But in order to please her, some people speculated about her meaning and helped her get things done. Click"

She compared her hand to a knife and waved it up and down, "Borrowing a knife to kill people, I have done everything I need to do." On the contrary, he picked himself cleanly, and he was still the perfect student in the eyes of teachers and parents. Look, how smart! ”

Cheng Han looked at Bai Tingting through the one-way mirror, although the child was a little nervous at the beginning, but when she said every word, she looked into Xie Wencong's eyes without a trace of dodge.

She looked at Song Qi's transcript earlier, thoughtful. The three people who are here today have three different descriptions of one thing. But the only thing these three stories have in common is that in their own stories, they are the most innocent, the most pitiful, or the most righteous people.

Closing the transcript, Cheng Han looked inside with a smile on the corner of his mouth, "It's a little interesting." ”

Xiao Rongzheng's phone rang, he looked at the caller ID, motioned to Xie Wencong next to him to let him stop first, and then walked out of the door, "What's wrong?" ”

The voice of a white dove came from the earpiece, "Boss, we have found the source of the murder weapon." It is an online store specializing in private customization, and those three letters are the initials of the store designer. I sent some pictures of the store's products to your phone, and the marks are the same. Moreover, after our communication with customer service, the person who bought the murder weapon was called Bai Jinglin. ”

"Bai Jinglin?"

"Yes, he is Bai Tingting's father!"

Xiao Rongzheng's brows furrowed deeper and deeper, and after a few seconds, he hung up the phone. He grabbed the doorknob, adjusted his breathing, and walked back in with a dark face.

With a "snap", Xiao Rongzheng put the phone in front of Bai Tingting hard, startling her. Immediately afterwards, Xiao Rongzheng asked sharply, "Have you ever seen this?" ”

Bai Tingting was taken aback, and almost cried when she looked at the pictures on her phone. The picture was taken from the scene of the crime, the knife in Hu Sasa's abdomen. Although the surrounding pictures were mosaiced by Xiao Rongzheng, the silhouette of the person can still be roughly seen.

"I designed it myself, how did I end up here." She lost the composure she had just now, and there was a clear cry in her voice.

"Do you ask us? Isn't that a question for us to ask you? Come, tell me, how did the dagger you designed yourself stick to Hu Sasa's body? The sense of oppression on Xiao Rongzheng's body made Bai Tingting tremble.

"I really don't know! I secretly took this to school once, and I never found it again. I've been losing it for weeks, and if I hadn't seen it today, I'd have forgotten I ever had this knife. Besides, Uncle Policeman, if I am the murderer, what should I do when I take the initiative to come to you? Throwing yourself into the net? ”

Xiao Rongzheng raised his eyebrows, although he was skeptical, he still took the phone back.

"You bought it in your father's name?"

"Hmm", Bai Tingting couldn't stop nodding.

"Alright, you should get here today. If you have any questions, we will get in touch with you at any time, and we hope that you will cooperate seriously when the time comes. ”

The little girl had red eyes, nodded, and sniffed. The smile and enthusiasm on his face when he came was like two people.

"What are you laughing at?" walked out with Bai Tingting, and saw Cheng Han leaning on the opposite wall, smiling narrowly.

"It's okay, I just want to laugh." Cheng Han finished watching the excitement and was about to go back to continue eating, but was dragged by Xiao Rong.

When I turned around, I saw him looking at her with a smile, "Teacher Cheng and I will send classmate Bai home, there is someone she knows, she can rest assured that she will not be afraid." ”

couldn't resist him, and in the end he could only be half-pulled and half-dragged by Xiao Rongzheng into his car.

Along the way, none of the three people in the car spoke. Bai Tingting even sat in the back, pretending to look at the scenery, not wanting to make eye contact with anyone in front of her. After all, when things implicate themselves, no one can be left unconcerned. What's more, the murder weapon was indeed made by her.

"Goodbye teacher, goodbye uncle policeman!"

As soon as she arrived at her destination, Bai Tingting got out of the car like a gust of wind and ran home without looking back, for fear that Xiao Rongzheng would not be able to go home if something was wrong.

Seeing the little girl gradually running away, Cheng Han leaned on the back of the seat and laughed softly.

"Xiao Rongzheng, you just acted too deliberately."

"Huh? Have it? Xiao Rongzheng touched his face, and smiled with Cheng Han with some embarrassment, "It's not because this child is too sophisticated and sleek, I'm afraid that I will directly confront her, and she will be able to come up with any reason to prevaricate." So she could only surprise her and let her tell the truth in a hurry. ”

As he said this, a sly glint flashed in his eyes.

"Aren't you afraid that she will complain about you?"

"It's nothing, but maybe a few people will have to be sent to closely monitor Bai Tingting first, in case she lies, or she will contact the real murderer."

When Cheng Han and the two of them returned to the office, their takeaway was still on the table as when they left. However, the original crab roe tofu has become a lump, and the rice has evaporated some water due to prolonged contact with the air, and it has become dry and hard.

If it were normal, Cheng Han might not move anymore. But now she is hungry, and she doesn't care whether it's hot or cold, she just picks up the lunch box and puts it in her mouth. Xiao Rongzheng stretched out his hand to stop her, and then handed her a cup of hot water.

"I just came back from outside, and I took a breath of cool air, if you eat like this, your stomach will hurt."

Cheng Han obediently took the water cup, drank it with a bang, and specially turned the bottom of the cup upside down to show him. Xiao Rongzheng felt that she was really cute like this, but she still asked worriedly, "Do you want to order another takeout for you?" Don't spoil your stomach. ”

"It's okay, it's a pity to throw away this good meal. I just take hot water and soak the rice to eat, and I don't pay so much attention to it. And, that's how everyone eats, isn't it? ”

After speaking, he picked up the chopsticks and put the rice into his mouth one by one. In that way, I don't know, I thought she was eating a full banquet.

"Knock Knock"

A slender, sunny-looking forensic doctor knocked on the door and walked in.

"The autopsy results are in." After speaking, he put the autopsy report in Xiao Rongzheng's hand, and wanted to leave, but was grabbed by Xiao Rongzheng.

"It's all here, Mingming, you, a professional, will tell everyone about it."

Ye Mingming didn't shirk it, and walked directly to the front with the report, "The deceased was injured in the abdomen with a sharp weapon, the wound was 3.5 centimeters long and 6 centimeters deep, and he was injured to the vital point, and he died of excessive blood loss. At the same time, the deceased had a slight fracture of the ankle of his left foot. The time of death was October 30, between half past four and half past five in the afternoon. And according to the analysis of the extent of the food residue in her stomach, she should have eaten shortly before she was killed, and she ate zongzi with bean paste filling. ”

"Dousha dumplings?" Xu Ranran couldn't hold back and asked. She hurriedly covered her mouth and subconsciously glanced at Ye Mingming.

Ye Mingming pursed his lips, nodded, and patiently explained, "Everyone knows that things like zongzi and glutinous rice balls are not easy to digest, and they can't be eaten more. Therefore, the residue found in the stomach of the deceased is relatively intact and can be detected relatively easily. In addition, the alcohol content of the deceased was 50mg/100dl, which means that he had had alcohol intake before his death. ”

He looked at Xu Ranran, "Officer Xu, do you have any questions?" ”

"No, no. Forensic Doctor Ye said very clearly, I really have no problem, no problem! Xu Ranran smiled dryly, revealing her white and neat eight teeth, and gave Ye Mingming two thumbs up.

"Well, that's fine. Team Xiao, the report is here, I still have something to do below, let's go first. ”

It wasn't until he disappeared at the door that Xu Ranran's far-fetched smile gradually disappeared. She rubbed her sore cheeks, leaned her head on Cheng Han's shoulder, and beat her chest secretly.

Cheng Han saw this forensic doctor for the first time, and he couldn't help but be a little curious when he saw Xu Ranran, who was not afraid of heaven and earth, so afraid of him. But thinking about finishing the case first, he began to reminisce about Ye Mingming's words just now.

Bean paste dumplings? Alcohol?

Hu Sasa is obviously still a minor, how can she drink alcohol in school, let alone in front of the C position she finally won over. I thought the truth would come out with the autopsy report, but it became more and more confusing.

Xu Ranran, who had always been like an ostrich, suddenly raised her head, as if she remembered something, "I remember, Hu Xiaoxiao went to school today to deliver food to her sister." Since the two of them have agreed in advance, why does Hu Sasa still eat this? ”

Cheng Han then added his questions, "Moreover, Hu Sasa finally ate the food." This shows that she knows this person and should have a good relationship, otherwise, how would she accept food from strangers. So, what exactly is the purpose of this person? ”

Xiao Rongzheng was sorting out his notes on the side, and his brows had hardly stretched since he returned to the police station.

"She was a minor and had violated the school's rules by drinking alcohol during school hours. But who exactly brought alcohol into school? Who can make Hu Sassa let down his guard? ”

He flipped through his notes and continued, "After integrating all the information so far, we can generally conclude that the murderer is first of all the people around Hu Sasa, who can come and go in the school at will. Moreover, there was a conflict between that person and the deceased. Tomorrow, let's go to the deceased's house to investigate and see if we can get more clues from her home. ”

"White pigeon, you can help keep an eye on the Internet to see if anyone is discussing this case on the Internet, and if there is, notify me immediately!"
