Criminal Investigation Notes

Song Wen instructs the others to continue their investigation in the school. Then he drives Audi back to the city council with Lu Siyu and Fu Linjiang.

They have been busy in the middle of the night, but for others, it's just an ordinary morning, shops open one after another, pedestrians and vehicles are in a hurry on the street, and the busy life of the day has just begun.

No one on the earth will run as usual, everyone is concerned about themselves, it seems that no one has noticed that two young girls died in the dormitory last night.

As soon as it was time to go to work in the Municipal Bureau, there was still a bit of noise in the police station. Several girls in the household registration department saw that Song Wen was dressed in formal clothes, and her eyes were a little straight. After they responded, they said hello one after another. Song Wen nodded a few times and went directly into the office of the Gu Bureau.

Gu Ju sat on the table with a dignified face. He didn't care to make chrysanthemum tea. When he saw Song Wen come in, he first made an official speech: "this case Leaders at all levels attach great importance to it. I've had four or five calls since the crime last night. "

Song Wen nodded his head and said, "I know that we are also paying close attention to the investigation. Now we have some clues."

"You're so quick to give me such a surprise?" Gu Ju said and took a few photos of Song Wen wearing flowered trousers. He glanced at Song Wen and said, "now it's dressed like a dog. What did you do before? Two of them are complaints about you! "

Song Wen is a bit helpless, deeply realized what is called good things, no one knows, bad things spread thousands of miles, he was not the leader to midnight to order the past? After looking at the photo, he said, "I changed my clothes, so no one took any pictures. At least make a comparison picture."

Gu Ju heard this in the early morning, and his lungs would be blown up. Seeing Song Wen's attitude, he pointed his finger at the photo and said, "do you know how sensitive this case is? All kinds of media are waiting for news. Do you dare to dress up like this?! Did you read what the Internet said? Do you want to recite the police requirements? You've been an old criminal police officer for many years, and you're still digging this basket? You've disgraced the face of our police force

Song Wen knew the mistake in his heart and said, "Gu Ju, what they said is the MVP of our police station for two consecutive years."

Gu Ju raised eyebrows: "Stinky boy, what's your attitude? You want to write a check, don't you? "

"I promise not to do it again, but what now?" Song Wen sighed, joking and pretending to break the blame. "Or I'll resign and give the case to another team?"

"Don't think about how to make up for your mistakes, just think about stepping back?" After hearing this, Gu Ju was even more angry and snorted, "how's the case?"

Song Wen stopped joking, and zhengse reported: "the autopsy of Laolin has been completed and the cause of death has been determined. One of them died of poisoning, the other was suffocated by quilt. Up to now, the source of poison has not been found, but the suspect has been basically locked in and committed a crime in the bedroom. We have talked to the relevant personnel of the case to understand the case. "

Gu Ju was quite satisfied with the efficiency of this work, and then told him: "at present, the impact is limited to the campus network of Nancheng University. You must solve the case within a week, and you have to explain to the public." He always loved talent and protected his weaknesses most. He had already made arrangements to help song wendang go to 7788, which brought him back for accountability.

Song Wen held his breath and looked up at Gu Ju: "three days, I will give you a military order, three days I will put the results on your table."

Gu Ju loved Song Wen's character and nodded: "well, if you can solve the case in three days, I'll ask you to take this year's police propaganda video. If you can't break it, I'll enlarge the photo and paste it at the door of the police station."

Song Wen came out of Gu Ju's office and went to the work area. He saw Fu Linjiang looking at him with a smile. He didn't need to ask. The deputy team also knew what happened last night. Song Wen was a little angry. Fu Linjiang pulled him over and said, "Song team, if Gu Ju says anything, you don't care. In my opinion, it's a good thing. In the past, you always had a meticulous attitude, and the whole person was tense. You drew well and solved a case quickly. You are a police captain who speaks his word. We dare not reveal anything on the surface, but we are afraid of you behind our backs. But this time, you seem to be contaminated with some human fireworks, more approachable

After hearing this, Song Wen thanks Fu Linjiang for his understanding and comforts him in time. He turns his head and says, "that's not a big deal. I didn't go to my heart. Let's have a meeting. The most important thing at present is to sort out the details of this case."

Fu Linjiang quickly made arrangements and gathered all the people to the meeting room. Xu Yao just came to work. She reached for her long hair with a hairband. Xiaocheng didn't sleep for half a night. Yawning, she busily summarized all kinds of situations of yesterday. After meeting Xu Yao, Song Wen asked, "what about brother Lin? Not back yet? "

Xu Yao said: "he came out of the funeral home and went directly to the hospital. He is still there."

Song Wen nodded and asked the hospital to know more about the situation: "it's hard. How is your situation here?"

"Most of the identification results of yesterday have come out. We have also entered the fingerprint of four people into the system. There is no sign of damage to the door lock of the dormitory. There is no sign of entering each entrance. There are no other suspicious personnel in the monitoring outside the dormitory building. In many chocolate residues, we have detected the poison. We can basically be sure that the poison is in the chocolate Then we found Guo's fingerprints on the box Cheng Xiaobing, as the material evidence that went to the scene last night, began to introduce the situation. She stopped here, looked up at Song Wen and said, "it can be said that her fingerprints are all over the place. And Only her fingerprints are clear enough. ""I also found that before May 1, Guo Yi placed an order for a box of high-grade handmade candied heart chocolate in an online shop. It should be this box." Zhu Xiao spoke and opened the computer, several people's accounts and various information had been opened last night. Look at this time, just before the white novel, they broke out after the last conflict.

"This chocolate is a net red chocolate with a crispy outer layer and chocolate sauce inside. It is thick like magma, so it is also called magma chocolate. Because of this characteristic, this kind of chocolate is widely loved by sweets lovers. Because it is handmade, it is not resistant to high temperature and is inconvenient to transport. Therefore, it is only available in limited quantity from September of one year to May of next year. This kind of chocolate has always been in short supply. According to the time, Guo's is almost the last batch. "

"Well, the thick chocolate paste is all over the bedroom, on the bed, on the floor, in the garbage can, under the shoes, even in the bathroom, we found some residue and thick paste." Cheng Xiaobing complained that it was because of this that they were busy for half a night yesterday.

"Has the thick chocolate been sent to the laboratory?" Song Wen asked.

Xu Yao nodded: "have been collected, written number sent to the past, but estimated that the results will be later."

"Have their phones been deciphered?" Song Wen asked again.

"Only Lin wanwan's Android was cracked. Guo Zhen, Dong Fang and Ma Aijing used Apple phones." Even if the police's investigation is cumbersome, it's better than Apple's mobile phone to crack the case. Swiping the phone violently will destroy the original data in the mobile phone.

Song Wen nodded: "apply according to the process first."

"But we found one thing." Xu Yao said that she sold three mobile phones in the material evidence bag and showed them to the public. These three are new apples, but the colors are different. "On Guo's mobile phone, we found Lin wanwan's fresh fingerprints, which were also stained with some thick chocolate syrup. She made an emergency call with Guo's mobile phone. At that time, the scene was very chaotic. The three mobile phones were stained with some chocolate. Some of them may have been accidentally rubbed on, and some are vomit. We have extracted them. "

Song Wen frowned slightly when he heard this: "isn't the Guo family always in a bad economy? How could she use such a valuable mobile phone? "

Apple's mobile phone is a high-end machine, let alone a new model. The price is high for ordinary college girls.

"That's a good question." Zhu Xiao flipped through the record and said, "I also have this question. Later, I found out that Guo Zhen bought the mobile phone after winning a scholarship from the school."

This makes sense, girls, after getting a large sum of discretionary bonus, impulse consumption is also justifiable. In this dormitory, three people all used a mobile phone, but it seemed that Lin wanwan was special. Song Wen said, "give us a study of Lin wanwan's mobile phone."

Listening to their discussion on the mobile phone, old Jia was worried, "well, we're not talking about poisoning cases. Don't always go around the mobile phone. In my opinion, the case is quite clear. We can now confirm that the source of the poison is chocolate. Guo's fingerprints are all on the box of chocolate. She bought all the chocolate. She probably wanted to revenge her classmates for the violence on campus

This is a complete idea.

Song Wen asked old Jia, "then I ask you, since it was Guo Zhen who poisoned her, why did she finally go out and call for help?"

Lao Jia scratched his head: "this Maybe it was too painful after the poisoning? "

Song Wen asked again, "what about the poison source?"

"Maybe it's from the chemistry department." Where did Lao Jia pat his head again? Seeing that no one responded to him, he said, "I'll check on the key points of the next step. Song team, in addition to Guo Zhen, there is Lin wanwan left. You don't doubt her, do you? Although she is not deeply poisoned, but so far, there is no evidence. We have done a round of follow-up, and the girl's evaluation is the best. " Now that the case has been investigated, Lin wanwan is innocent like a bystander, with neither motive nor direction.

"It's because there's none, so it's suspicious." Song Wen did not come to a conclusion. This case seems to be a simple alternative. In fact, there are many possibilities, such as collaborative crime.

Xu Yao ignored old Jia and passed him by. He took Lin wanwan's mobile phone and handed it to Song Wen. Then he handed over a form. "Fingerprint information has been filed. We have checked it. Nothing is particularly valuable. You sign it and take it away."

"Well, let us know later if there is any clue." Song Wen signed his own name and took the mobile phone in his hand. "Let's get started. I've made a military order with Gu Bureau."

Zhu Xiao asked, "how many days this time?"

Song Wen's character, and Gu Ju set up military writ is a common thing. Although he is a bit arrogant and doesn't play cards according to the rules, he is really capable and lucky. Other people are bragging, but he is really bullish. As a captain, this military order has not been overtime.

Listen to Zhu Xiao ask him, Song Wen used his hand to draw a three, up to now, the first day has been more than half. This case is a little tricky, and it needs time.Out of the conference room, Song Wen turned around and gave the mobile phone to Lu Si Yu standing behind him. "You can look through it first. What's the clue?"

Lu Siyu was stunned at first. He stopped and hesitated for a moment. Then he lowered his head and took the mobile phone to his hand. He went to his seat to turn on the mobile phone. The mobile phone was an ordinary Android machine. It was a common model a few years ago. It was cheap, functional and cost-effective.

The mobile phone is a bit old. It seems that I haven't changed it since I bought it in my freshman year, but it's well preserved. When I press the power button, the screen is the simplest inherent setting, and I haven't even changed a wallpaper. Now the password has been broken, you can directly open the commonly used software to view.

Due to the long history of this mobile phone and the lack of memory, there are not a lot of software above, only a few commonly used.

Lu Siyu tried wechat and QQ, and found that he needed to input a password. Instead, he opened a short message with a few pieces of junk information lying in it. Then he opened the phone again. There was not much call. Maybe it was deleted. There was a phone call a few days ago. It was often a takeout, express delivery or intermediary. After looking down a few pages, he saw a call to her mother. Lusi frowned and nodded again Open the browser, is traceless browsing mode, the past search words deleted clean.

Playing with the mobile phone, Lu Si Yu pointed out all the places that could be opened, and felt that the cell phone battery was going to run out. After a while, the power went down a lot. He reached out to find the charger, looked up and saw that Song Wen was staring across a glass. His expression was rarely serious and his jaw line was slightly tight.

Lu Si Yu has to admit that this man is really handsome. After wearing his clothes, he has a sense of reliability between a mature man and a young man. He has a pleasant temperament. He seems arrogant, but in fact, he has the courage to break the rules, as well as the sharpness of a hunter. When he is fully engaged, he is more charming. In this regard, he is a natural criminal policeman.

Song Wen is confident and passionate. Unlike him, Lu Si Yu knows clearly in his heart how cold he looks and how uneasy he is. He is like a strange man walking in the world, hiding himself with that cold and protecting himself from those human beings.

At this time, he found Lu Siyu looking at him. Song Wen raised his eyes, turned his head and asked, "what do you think of Lin wanwan?"

Then Lu Si Yu stopped thinking, arranged his thoughts and slowly opened his mouth: "he is a clever, clean, but very careful person. Either she's an extremely innocent passer-by, or she's a criminal who's extremely disguised. "

From Lin wanwan's body, he felt a kind of good girl that adults expected. She stood in the crowd and looked like many people. She was warm, obedient and obedient. She had an ordinary origin, a white face, a pitiful appearance and excellent achievements. But she is a little different, other people's emotions are still floating on the surface. And this girl, no matter how they search for it, gets very little. They never touch her inner world.

At this time, when Song Wen's mobile phone rang, he looked down and said, "we have a chance to ask her in person. Lin wanwan finally wakes up after a short message from the medical examiner Lin Da."
