Criminal Investigation Notes

Song Wen urged the others to continue their investigation at the school, and then drove the Audi back to the city bureau with Lu Siyu and Fu Linjiang.

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

When the earth is gone, no one will operate as usual. Everyone is caring about themselves. No one seems to notice. Two young girls in the season died in the dormitory last night.

When the city bureau arrived at work, there was still a bit noisy in the police station. The little girls in the household registration department straightened their eyes when they saw Song Wen in a formal suit. After reacting, they all said hello. Song Wen nodded and responded a few times. Walked directly into Gu Ju's office.

Gu Ju was sitting on the table with a solemn expression. He didn't even bother to make chrysanthemum tea. Seeing Song Wen coming in, he made an official statement: "This case... Leaders at all levels have taken it seriously. From last night to the incident. Now I have answered four or five calls here."

Song Wen nodded and said, "I know, we are also investigating the case, and now we have some clues."

"Are you really good enough to give me such a surprise?" Gu Ju took a few photos of Song Wen wearing fancy pants, his eyes swept over Song Wen, "Now it's well dressed. Dog-like, what did you do before? Two of the calls are complaining about you!"

Song Wen was a little helpless. He deeply realized what good things mean by no one knows, and bad things spread thousands of miles. Wasn't he instructed by the leader to pass by in the middle of the night?I looked at the photos and said, "Why didn't I take pictures after I changed clothes? Anyway, make a comparison chart."

Gu Ju heard this early in the morning, and his lungs were about to explode. Looking at Song Wen’s attitude, he nodded the photo with his finger and said, “Do you know how sensitive this case is? Various media are waiting for news. Do you dare to dress up like this?! Did you read what you said on the Internet? Do you want to memorize the police request? You are also an old detective for many years, and you still stabbed this basket? Our police force has all the faces lost by you! "

Song Wen knew his mistake in his heart, and still insisted: "Gu Ju, they are talking about our police department's MVP for two consecutive years."

Gu Ju raised his eyebrows: "Smelly boy, what is your attitude? You want to write an inspection, right?"

"I promise I won't commit another crime next time, but what should I do now?" Song Wen sighed, jokingly pretending to break the monster, "Or I will resign and give the case to another team?"

"I don't want to make up for it, just thinking about retreating?" Gu Ju became even more angry after hearing this. After dismissing the horse, he snorted, "How is the case investigated?"

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

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

Song Wen sighed and looked up at Gu Ju: "Three days, I will give you a military order, and 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 will ask you to take this year’s police promotional video. If you can’t, I will enlarge the picture and post it at the entrance of the police station. ."

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. You don’t need to ask to know that the deputy team also knew what happened last night. Song Wen was a little angry, and Fu Linjiang took He pulled over and enlightened: "Team Song, don't care if Gu Ju says anything. In my opinion, it's a good thing. In the past, you always had that meticulous attitude, and the whole person was tense. , You paint well and solve the case quickly. He is a police captain who speaks out. Everyone dare not show anything on the face, but they are afraid of you. But this time, your body seems to be contaminated with human fireworks. Much more approachable."

After hearing this, Song Wen thanked Fu Linjiang for his understanding and relief in time. He turned his head and said, "That's not a big deal. I didn't take it to heart. I will wait for everyone to have a meeting. The most important thing is right now. We still have to sort out this case."

Fu Linjiang quickly made arrangements and gathered everyone in the meeting room. Xu Yao just came to work, stretched out her hair to wrap her shawl's long hair, Xiao Cheng stayed up for half the night, yawning and busy gathering yesterday’s Various situations.After Song Wen met Xu Yao, he asked, "Where is Brother Lin? Haven't come back yet?"

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

Song Wen nodded. At this time, he should also learn more about the situation with the hospital: "Thanks for your hard work, how is your situation here?"

"Most of the appraisal results came out yesterday. We have also entered the fingerprints of the four people into the system. The dormitory door locks showed no signs of being broken, the entrances showed no signs of entering, and the surveillance outside the dormitory building showed no other suspicious persons entering or leaving In the chocolate residues in many places, we tested the poison. It was basically certain that the poison was in the chocolate, and then we found Guo Wei’s fingerprint on that box.” Cheng Xiaobing started as the physical evidence of the scene last night. Introducing the situation, she stopped here for a while and looked up at Song Wen, "It can be said that her fingerprints are all over her. And...only her fingerprints are clear enough."

"I also found here. Before May Day, Guo Wei ordered a box of high-end handmade candy heart chocolates in an online store. The packaging should be this box." Zhu Xiao spoke and turned on the computer. Various information has been opened and available for checking last night.Looking at this time, it happened to be from the previous Bai Xiaoshu, after their last conflict broke out.

"This chocolate is a net red chocolate with a crispy skin on the outside and chocolate sauce on the inside. It is thick like magma, so it is also called magma chocolate. Because of its characteristics, this chocolate is popular with sweets lovers. Because it’s handmade, it’s not resistant to high temperatures, and it’s not convenient to ship, it’s only available in limited quantities from September to May of the year. This chocolate has always been in short supply, depending on the time, Guo Wei’s decision is almost the last one. Batch."

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

"Has the thick chocolate paste sent for testing?" Song Wen asked.

Xu Yao nodded: "I have collected everything and wrote the number and sent it, but it is estimated that the result will be later."

"Did their phones decipher it?" Song Wen asked again.

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

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

"But we found one thing." Xu Yao said that he sold another key here, and took out three mobile phones in the evidence bag, and showed everyone that these three are new apples, but they are different in color. "On Guo Wei’s mobile phone, we found Lin Wanwan’s fresh fingerprints, and the fingerprints were stained with some thick chocolate paste. She used Guo Wei’s mobile phone to make an emergency call. The scene was very messy. There is some chocolate on every cell phone, some may be accidentally rubbed on, and some are vomit, which we all extract."

Song Wen frowned slightly when he heard this: "Didn't Guo Wei's family have always been economically unwell? How could she use such an expensive mobile phone?"

Apple's mobile phones are considered high-end phones, let alone new ones, and the price is high for ordinary college girls.

"This question is a good question." Zhu Xiao flipped through the records and said, "I also have this question. Later, I checked and found that Guo Wei bought the mobile phone after receiving a scholarship from the school."

This makes sense. Girls, after receiving a large extra bonus that can be freely administrated, it is excusable to spend on impulse.In this dormitory, all three of them used a mobile phone, but it seemed that Lin Wanwan was special. Song Wen said, "Let us study Lin Wanwan's mobile phone."

Listening to them discussing on the mobile phone, Lao Jia was anxious, "Well, we are not discussing the poisoning case, don't always go around the mobile phone. From my perspective, the case is quite clear. We can now determine that the source of the poison is chocolate. , The chocolate box is also full of Guo Wei's fingerprints, and she bought all the chocolates. She probably wanted to avenge her two classmates who had violence on campus."

Putting it together in this way is a complete idea.

Song Wen asked Lao Jia: "Then I will ask you, since it was Guo Wei who poisoned her, why did she go out to call for help in the end?"

Old Jia scratched his head: "This...probably it was too painful after the poisoning?"

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

"Maybe it was from the handsome guy in the chemistry department." Where did Lao Jia pat his head, no one responded to his own reason. "I will check the focus of the next step. Team Song, except for Guo. Hu, Lin Wanwan is left. You don't suspect her, are you? Although she is not deeply poisoned, but so far, there is no evidence. We did a round of follow-up and this girl gave her the best evaluation." The investigation of the case till now, Lin Wanwan looks innocently like a bystander, with neither motivation nor direction.

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

Xu Yao ignored Lao Jia, brushed past him, took Lin Wanwan’s mobile phone and handed it to Song Wen, and then handed over a form, “The fingerprint information has been archived. We have simply checked it, nothing The ones that are especially valuable, you sign and take your phone."

"Well, let me know if you have any clues later." Song Wen signed his name and held the phone in his hand. "Everyone, let's start work. I can make a military order with Gu Ju."

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

Song Wen's character is commonplace with Gu Ju's military order.Although he is a bit arrogant and doesn't play cards according to the rules, he is really capable and lucky. Others are bragging, but he is really awesome. As the captain, this military order has not expired once. .

Hearing Zhu Xiao asked him, Song Wen made a gesture of three with his hands. By now, the first day has passed halfway.This case is a bit tricky, and we need to hurry up.

Walking out of the meeting room, Song Wen turned around and gave the phone to Lu Siyu, who was standing behind him, "Look through it first. Any clues."

Lu Siyu was taken aback for a moment, stopped, 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 device. This is a common model with low price and complete functions and high cost performance.

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

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

Lu Siyu tried WeChat and QQ, and found that he needed to enter a password, and instead opened the text message with a few spam messages lying in it. Then he turned on the phone again. There were not many calls. Maybe it was deleted. There was only a few days. The phone is often a takeaway, courier, or intermediary. After turning down a few pages, I saw a call to her mother. Lu Siyu frowned and opened the browser again. It was in the seamless browsing mode. The search term was deleted cleanly.

Fiddling with the mobile phone, Lu Siyu clicked on all the places that could be opened, and only felt that the battery of this mobile phone was about to die. After just a while, the battery was down a lot.He stretched out his hand to find the charger, and when he looked up, he saw Song Wenzheng in a daze across the glass. His expression was rarely serious and his jaw line was slightly taut.

Lu Siyu had to admit that, in this way, this man is really handsome, especially after wearing his clothes, he has a sense of reliability between a mature man and a young man.He has a likable temperament, which seems a little arrogant, but in fact he has the passion to go forward. He has the courage to break the rules and the hunter-like keenness. When he is fully engaged, he appears more charming. In several terms, he is a natural criminal policeman.

Song Wen is confident and fierce. Unlike him, Lu Siyu knows in his heart how indifferent he looks and how uneasy he is. He is like a stranger walking in the world, using that coldness. To hide yourself, to protect yourself by staying away from those humans.

At this moment, finding that Lu Siyu was looking at him, Song Wen raised his gaze, turned his head and asked: "What do you think of Lin Wanwan?"

Lu Siyu stopped thinking about it, sorted out his thoughts, and said slowly: "I am 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 people, warm, submissive, and obedient. She had an ordinary background, and she was pure and fair. Face, pitiful look, excellent grades.But she is a little different, the emotions of others are still floating on the surface.And this girl, no matter how they searched and found, very little was known, and they never touched her inner world.

At this time, when Song Wen's cell phone rang, he looked down and said, "We have the opportunity to ask her in person. Forensic Doctor Lin sent a text message and Lin Wanwan finally woke up."
