Criminal Investigation Files

Song Wen told the others to continue investigating at the school, and then drove the Audi back to the Municipal Bureau together with Lu Siyu and Fu Linjiang.

They have been busy in the middle of the night, but for others, it is just an ordinary morning. Various shops are opening one after another, pedestrians and vehicles are hurrying on the street, and the busy life of the day has just begun.

Everyone on the earth will continue to function as usual, everyone is concerned about themselves, and no one seems to have noticed that two young girls died tragically in the dormitory last night.

The city bureau had just arrived at work, and the police station was still a bit noisy. The girls from the household registration department saw that Song Wen was dressed in a formal attire, and their eyes were a little straightened. After realizing it, they all greeted each other. He walked directly into Gu Ju's office.

Gu Ju sat on the table with a serious expression on his face. He didn't bother to make chrysanthemum tea. When he saw Song Wen coming in, he said in an official tone: "This case... the leaders at all levels attach great importance to it. From the incident last night to the Now I have answered four or five calls here."

Song Wen nodded and said: "I know, we are also hurrying to investigate the case, and now we have some clues."

"You really hurry up, and you gave me such a surprise?" Gu Ju took a few photos of Song Wen wearing floral trousers while talking, and glanced around Song Wen, "Now you are dressed so nicely." Like a dog, what did you do before? Two of the calls were complaining about you!"

Song Wen was a little helpless, and he deeply realized what it means that no one knows about good things, and bad things spread thousands of miles. Wasn't he instigated by the leader in the middle of the night?He looked at the photo and said, "Why didn't anyone take a picture after I changed my clothes, let's make a comparison picture."

Gu Ju heard this early in the morning, and his lungs were about to explode. Looking at Song Wen's attitude, he pointed at the photo with his finger and said, "Do you know how sensitive this case is? All kinds of media are waiting for news. Do you still dare to dress up like this?! Have you read what is said on the Internet? Do you want to recite the police request? You are also a veteran criminal policeman for many years, and you still stab this basket? You have completely embarrassed our police force! "

Song Wen knew his mistake in his heart, but he said firmly: "Gu Ju, what they are talking about is the MVP of our police department for two consecutive years."

Gu Ju raised his eyebrows: "Brat, what's your attitude? You want to write an inspection?"

"I promise I won't do it again next time, but what should I do now?" Song Wen sighed, jokingly pretending to be a monster, "Why don't I take the blame and resign and pass the case to another team?"

"Don't think about how to make up for the mistakes, just think about retreating?" Hearing this, Gu Ju became even more angry, and after getting off his horse, he snorted, "How is the investigation going?"

Song Wen stopped joking and returned to the report: "Old Lin's autopsy has been completed and the cause of death has been determined. One of them died of poisoning, and the other was smothered to death by a quilt. The source of the poison has not been found yet. However, the suspect has been basically identified, and the crime was committed in the dormitory. We have already talked to the relevant personnel of the case to understand the case."

Gu Ju was quite satisfied with the efficiency of this work, so he told him: "Currently the impact is only limited to the campus network of Nancheng University. You must solve the case within a week and have an explanation to the public." He has always loved talent, The most important thing is to protect his shortcomings, and he has made arrangements long ago to help Song Wen get out of the way, so he was called back to be held accountable.

Song Wen took a deep breath and looked up at Gu Ju: "In three days, I will issue a military order for you, and in three days I will put the results on your table."

Gu Ju loves Song Wen's character, nodded and said: "Okay, if you solve the case in three days, I will let you take a promotional video for this year's police force. If you can't solve it, I will enlarge the photo and paste it at the police station entrance .”

Song Wen came out of Gu Ju's office and walked towards the work area. He saw Fu Linjiang looking at him with a smile on his face. He didn't need to ask. He pulled him over and said, "Captain Song, don't worry about what Gu Ju said. In my opinion, this is a good thing. In the past, you always had that meticulous attitude, and your whole body was tense." , you are good at drawing and solving cases quickly. You are a captain of the criminal police who promises everything. Everyone dare not reveal anything publicly, but they are all afraid of you when they recite it. But this time, you seem to be contaminated with some human fireworks. Much more approachable."

Hearing this, Song Wen thanked Fu Linjiang for his understanding and timely relief, then turned his head and said, "That's not a big deal, I didn't take it to heart, let's go to a meeting later, the most important thing right now is We still have to figure this case out.”

Fu Linjiang quickly made arrangements and gathered everyone in the conference room. Xu Yao just came to work, and stretched out her hand to wrap her long hair in the shawl with a hair tie. various situations.After meeting Xu Yao, Song Wen asked, "Where's Brother Lin? You haven't come back yet?"

Xu Yao said: "He went straight to the hospital when he came out of the funeral parlor, and he's still there now."

Song Wen nodded. At this time, we need to know more about the situation with the hospital: "Thank you, how is the situation here?"

"Most of the identification results from yesterday came out. We have also entered the fingerprints of the four people into the system. There is no sign of damage to the dormitory door lock, no sign of entry at each entrance, and no other suspicious persons have entered or exited from the surveillance outside the dormitory building. , in the chocolate residues in many places, we tested the poison, and we are basically sure that the poison was put in the chocolate, and then we found Guo Hua's fingerprints on that box." Cheng Xiaobing started as the physical evidence of being at the scene last night. After introducing the situation, she stopped here and looked up at Song Wen, "It can be said that her fingerprints are all over the place. And... only her fingerprints are clear enough."

"I also found out here that before May [-]st, Guo Hua ordered a box of high-end handmade candied chocolates in an online store. It should be this box from the packaging." Zhu Xiao turned on the computer while talking, and several people's accounts and All kinds of information were opened and available for inspection last night.Looking at this time, it happened to be in Bai Xiaoxiao's novel before, after their last conflict broke out.

"This chocolate is an online celebrity chocolate, with a layer of crispy skin on the outside and chocolate sauce inside, thick like magma, so it is also called magma chocolate. Because of this characteristic, this chocolate is widely popular among sweet tooth lovers I love it, and because it is handmade, it is not resistant to high temperature, and it is not convenient to transport, so it is only available in limited quantities from September to May of the next year. This chocolate has always been in short supply. Depending on the time, Guo Wei's order is almost the last one. batch."

"Well, speaking of those thick chocolate pastes, they are everywhere in the dormitory, on the bed, on the floor, in the trash can, under the shoes, and even in the bathroom. We found some residues and thick pastes." Cheng Xiaobing complained. Because of this, they were busy for half the night yesterday.

"Has the chocolate thickener been sent for testing?" Song Wen asked.

Xu Yao nodded: "I have already collected them, written down the numbers and sent them over, but the results are estimated to be later."

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

"Only Lin Wanwan's Android phone has been deciphered. Guo Wei, Dong Fang, and Ma Aijing are using Apple phones." The security of Apple phones is much better than other phones. Even if the police need to investigate the case, A cumbersome application is also required to be able to crack it.Violent flashing will destroy the original data in the phone.

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

"But we found out one thing." Xu Yao said that she had another trick, and took out three mobile phones in the evidence bag, and showed them to everyone. These three are all new Apples, but the colors are different. "On Guo Hua's cell phone, we found Lin Wanwan's fresh fingerprints, which were stained with thick chocolate paste. She made an emergency call from Guo Hua's cell phone. The scene was chaotic at that time. The three There are some chocolates on each phone, some may be accidentally rubbed on, some are vomit, we have all extracted."

Song Wen frowned lightly when he heard this: "Hasn't Guo Wei's family been doing poorly all the time? How can she use such an expensive mobile phone?"

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

"That's a good question." Zhu Xiao flipped through the records and said, "I also had this question. Later, I checked and found out that Guo Wei bought the mobile phone after receiving a scholarship from the school."

This makes sense, girl, after getting a large amount of discretionary bonus, it is understandable to spend impulsively.In this dormitory, all three people used a mobile phone, which made Lin Wanwan seem special. Song Wen said, "Give us Lin Wanwan's mobile phone to study."

Hearing that they were discussing on the mobile phone, Lao Jia became anxious, "Oh, we are not discussing the poisoning case, don't always hang around on the mobile phone. In my opinion, this case is quite clear. Now we can confirm that the source of the poison is chocolate. The box of chocolates is covered with Guo Hua's fingerprints, and she bought the chocolates, she probably wants to take revenge on those two classmates who bullied her on campus."

So pieced together, it is a complete idea.

Song Wen asked Lao Jia: "Then let me ask you, since Guo Hua was poisoned, why did she go out and call for help in the end?"

Lao Jia scratched his head: "This... probably because the poison caused too much pain, right?"

Song Wen asked again: "What about the source of the poison?"

"Maybe I asked for it from the handsome guy in the chemistry department." Lao Jia patted his head again, seeing no one responded, and said, "Let me check the focus of the next step. Team Song, apart from Guo Hua, Lin Wanwan is the only one left, don't you doubt her? Although she is not deeply poisoned, so far, there is no evidence. We have done a round of follow-up visits, and this girl has the best evaluation." This Now that the case has been investigated, Lin Wanwan is innocent like a bystander, with neither motive nor direction.

"It's suspicious because there is none." Song Wen didn't come to a conclusion.This case seems to be a simple choice between the two, but there are actually many possibilities, such as collaborative crimes.

Xu Yao ignored Lao Jia, passed him by, took Lin Wanwan's cell phone and handed it to Song Wen, and then handed over a form, "The fingerprint information has been archived, we checked it briefly, and there is nothing wrong with it." Especially valuable, you sign it, and the phone is taken away."

"Okay, let us know if you have any clues later." Song Wen signed his name and held the phone in his hand. "Everyone, let's get to work. I have signed a military order with Gu Ju."

Zhu Xiao asked: "How many days this time?"

Song Wen's personality is a common occurrence with Gu Ju's military orders.Although he is a bit arrogant and doesn't usually play cards according to the rules, he is really capable and his luck is not bad. Others are bragging, but he is really awesome. Since he became the captain, the military order has not been timed out once. .

Listening to Zhu Xiao asking him, Song Wen made a gesture of three with his hand. Up to now, half of the first day has passed.This case is a bit tricky, and we need to hurry up.

After walking out of the conference room, Song Wen turned around and handed the phone to Lu Siyu who was standing behind him, "You look through it first, if you have any clues."

Lu Siyu was taken aback for a moment, stopped in his tracks, hesitated for a moment, then lowered his head and took the mobile phone in his hand, walked to his seat and turned on the mobile phone. The mobile phone was an ordinary Android phone. A common model, cheap price, complete functions, relatively high cost performance.

The phone is a bit old, it seems that it was purchased in freshman year and has not been replaced, but it is in good condition, Lu Siyu pressed the power button, the screen is the simplest inherent settings, not even a wallpaper has been changed.Now that the password has been broken, you can directly open the commonly used software to view it.

Due to the age of this mobile phone and insufficient memory, there are not many software downloaded on it, only a few commonly used ones.

Lu Siyu tried WeChat and QQ, and found that he needed to enter a password, so he opened the text message, and there were a few spam messages in it, and then he opened the phone again, there were not many calls, maybe they were deleted, and there was only one call in a few days The phone calls are often from takeaways, express delivery or intermediaries. After scrolling down a few pages, I saw a call to her mother. Lu Siyu frowned, and opened the browser again. It was in the private browsing mode. The search term for was deleted cleanly.

Fiddling with the phone, Lu Siyu tapped all the places that could be opened, only to feel that the battery of the phone was about to die, and after just a while, the battery drained a lot.He reached out to find the charger, and when he looked up, he saw Song Wenzheng staring blankly through a glass. His expression was rarely serious, and his jaw line was slightly tense.

Lu Siyu had to admit that this man looked really handsome, especially after wearing his clothes, he had a sense of reliability between a mature man and a young man.He has a pleasing aura about him, he seems a little arrogant, but in fact he is passionate and indomitable, he has the courage to break the rules, and he is as sharp as a hunter. When he is fully committed, he looks even more charming, just like this In a few points, he is a born criminal policeman.

Song Wen is confident and fiery. Unlike him, Lu Siyu knows in his heart that no matter how indifferent he looks, he is so uneasy inside. He is like a strange person walking in the world, using that cold Cover up yourself, and protect yourself by staying away from those humans.

Finding Lu Siyu looking at him at this moment, Song Wen raised his gaze, tilted his head and asked, "What do you think of this Lin Wanwan?"

Only then did Lu Siyu stop thinking wildly, sorted out his thoughts, and said slowly: "She is a well-behaved, clean, but very careful person. Either she is an extremely innocent passerby, or she is an extremely disguised criminal."

From Lin Wanwan's body, he felt the appearance of a good girl that adults expected. She stood in the crowd and looked like many others. She was warm, submissive, and obedient. She had an ordinary background and a white face. The face, the pitiful appearance, the excellent grades.But she is a little different, other people's emotions are still floating on the surface.As for this girl, no matter how they searched, they found very little, and they still couldn't touch her inner world.

At this moment, Song Wen's cell phone rang. He looked down and said, "We have a chance to ask her in person. Forensic doctor Lin sent a text message. Lin Wanwan finally woke up."
