Silver Snow Line [Criminal Investigation]

"Tell me, why would a sister who always agrees to her brother's requests tell him to fend for himself?"
Back in the office, Xie Qingfei stared at the whiteboard for a moment, then wrote a question mark next to Zhang Yan's name.

"If I had a brother like this, I would be considered civilized if I didn't slap him a few times. How could I tolerate his mischief until now?" Xi Ming pouted and said, "The parents favor the youngest son, and the younger brother only treats her as an ATM. Pregnant women are emotionally unstable, and he asked for 20 yuan. Zhang Yan must have been unable to tolerate it, and she let out all her dissatisfaction for so many years in one go."
Xie Qingfei didn't comment on his words: "This isn't the first time Zhang Yuheng has asked Zhang Yan for money, and he's obviously never been rejected. Why is this time special?"

"Maybe I can give you some clues."

A female voice came from outside the door. Xie Qingfei turned around and said happily, "Dai Lin!"
"Thank you, Captain." Dai Lin showed her usual shy smile, pushed up her glasses, and turned the laptop she was holding to the crowd. "The deceased Zhang Yan in the case you are investigating was an up-loader, with the online name 'Swallow Who Wants Freedom', who often liked to post some daily vlogs. Because she used her husband Wang Shuang's identity information when authenticating her account, she was not able to find it at first."
Xi Ming took a look and said, "Wow, there are quite a lot of fans."
Dai Lin said: "Her videos are of high quality. Although she doesn't have a team, the filming and editing are good, and the content is sweet, so she has a lot of fans."

Xie Qingfei took a quick look at the titles of several videos and found that, as Dai Lin said, the content was all about love. The earlier ones were more life-oriented, including "About the process of my love with Mr. W", "One room, two people, three meals, four seasons", "Mr. W's reaction when I gave him a pregnancy test stick as a gift", and so on.

"So, this account was actually a love record blog when it was first established. Is Zhang Yan a self-media person? No wonder she needs professional equipment like a camera."

Dai Lin said: "I have seen the video of her acquaintance experience before. She said that she met Mr. W at a volunteer activity. The two had a good first impression of each other, and gradually fell in love, until they reached the stage of discussing marriage. Mr. W grew up in an orphanage and worked part-time in the institution at that time. His financial conditions were very average. In Shengzhou, there were betrothal gifts of 6 or 8 yuan, but Zhang Yan had a younger brother, and her parents asked for more. W couldn't even afford a fraction, so the marriage naturally didn't happen. Fortunately, Mr. W was promising and had achieved success from scratch. The living conditions of the young couple have improved. On the contrary, two years ago, when Zhang's father's business ran into problems and relatives and friends were afraid to avoid him, it was Mr. W who helped to recover the losses. When the Zhang family saw that this prospective son-in-law was not only successful in his career, but also willing to help clean up the mess without forgiving each other, they finally handed over Zhang Yan's household registration booklet and agreed to the marriage of the two. In other words, they fell in love for six or seven years, and they became legal husband and wife when Zhang Yan was 35 years old."

Zhao Chongyun said: "Mr. W is Zhang Yan's husband Wang Shuang, and the other information also matches."

Xi Ming said: "It seems that Wang Shuang has a strong motive for murder. Is he the one who pulled out the memory card? First of all, he has no family to rely on. His wife's parents and brothers are his parents and brothers. However, this family is obviously not normal people who love their daughter. The exploitation his wife suffered at home before is now happening to him. It's okay to be filial to his father-in-law and mother-in-law, but his brother-in-law always asks for money, and it's not just small amounts. This kind of marriage life is not what he wants, and the origin of all this is because he married this wife, and his dissatisfaction is transferred to his wife. Only when Zhang Yan dies can he get out of this family."

Zhao Chongyun was surprised and asked, "It's not the first day that Wang Shuang has known Zhang Yan. They have been together for so many years. Didn't Zhang Yan tell Wang Shuang about her family situation at all?"

Dai Lin said: "Wang Shuang must know. 'Swallow Who Wants Freedom' said in the video that her parents favored her younger brother, so she never received any care from her family since her younger brother was born, and she was very depressed for a while. The appearance of Mr. W made her feel loved again, and she described him as a ray of light in her life. People only show their inner selves to those they absolutely trust. Zhang Yan confided her decades of pain to Wang Shuang, and it was Wang Shuang who accompanied her, comforted her, and brought her out. When she proposed to him, she also asked him if he minded her family situation, and Wang Shuang said personally that he didn't care."

"After all this time... is this really true love?"

Xi Ming casually clicked on one of the videos titled "Secretly Preparing a Birthday Surprise for Mr. W", which was posted shortly after the couple got married. Watching the interaction in the video, as a viewer, he can completely feel the love and tacit understanding between them. People will deliberately pay attention to their behavior and expressions in front of the camera, and try to show their best side. The real state is generally shown when they are alone. Since this video is intended to capture Wang Shuang’s first reaction to receiving a birthday surprise, the camera position is definitely set in the dark, and the filming also took place without his knowledge, so his series of reactions can best restore his true emotions——

His eyes always followed her, all his attention was on her, and the look in his eyes when he looked at her was filled with admiration and love.

Xie Qingfei looked through Zhang Yan's account homepage and said, "Human emotions are complex and changeable. Love and hate can even exist at the same time. How can we guarantee that Wang Shuang will always be deeply in love with Zhang Yan? Although bystanders and listeners can understand each other's experiences at the time of the conversation and have some worthless sympathy, they have not experienced the other person's life after all. Empathy is the most important prerequisite for mutual understanding. So just like Xi Ming said, when Wang Shuang really experienced everything Zhang Yan had experienced, he found that he could not accept it at all, so he was dissatisfied and complained. The image of his ideal partner also collapsed with reality. What would he think at this time? He would not think that he made the choice himself and accept this responsibility, but instead blamed his wife for not telling the truth at the beginning, and not persuading him a few more words, allowing him to be blinded by love and fall into this abyss."

Xi Ming said sadly: "If even he changed his heart and even killed his wife because of this, then Zhang Yan would be too miserable..."
Zhao Chongyun asked, "Captain Xie, should we ask Wang Shuang to come to the bureau next?"
Xie Qingfei closed the computer: "No, let's go to his house."
The word "we" instantly brightened up Zhao Chongyun's face: "Can I go too?"
"Yes." Xie Qingfei stood up and smiled at him, "Listen more, talk less."

It was nine o'clock in the morning.

Xie Qingfei slowed down along the roadside and stopped beside a breakfast shop that hadn't closed yet. He turned around and said, "What do you two want to eat? I'll go down and buy it."
Xi Ming was naturally not polite and said immediately: "I want a glutinous rice ball, two fried dough sticks, soy milk and a bowl of tofu pudding."
Xie Qingfei nodded and looked at Zhao Chongyun: "What about you?"
Zhao Chongyun looked bitter, and finally shook his head: "I'm not hungry."
"You have to eat even if you're not hungry. It would be embarrassing if you faint from exhaustion in someone else's house later." Xie Qingfei didn't allow him to refuse. "Since you don't want to tell me, you can eat whatever I buy."
Zhao Chongyun: "Really not..."
The sound of a door closing with a bang was his response.

Xi Ming leaned over the window and reminded: "I want salty tofu pudding with a spoonful of chili, and I want sweet soy milk. Thank you, Master!"
Tofu pudding and soy milk were both too much for Zhao Chongyun to handle. He covered his mouth and turned his head away silently.
"Why not eat? The breakfast here is delicious." Xi Ming expressed his incomprehension of his reaction.
Zhao Chongyun had no choice but to say, "I'm not used to eating at street stalls."
"Why are you as spoiled as my brother?" Xi Ming complained, "Someone is treating you, but you're still complaining about the rotten food."
"Of course I didn't mean that!" Zhao Chongyun explained quickly, a little embarrassed, "I just, I just lost my appetite after yesterday."
Xi Ming suddenly realized: "I should have known not to take you with me yesterday."

Not long after, Xie Qingfei came back with something in his hand, and sat back in the car, feeling cold. Xi Ming, who was sitting in the passenger seat, hurried over to help him take the car.
"I'm so hungry, Xiao Zhao, you really don't want to eat?"
Zhao Chongyun smelled the aroma. He would be lying if he said he wasn't hungry, but he couldn't get over it psychologically. Is that soy milk? It must be brain matter, a white mass, and very sticky...
Xie Qingfei glanced at him through the rearview mirror and threw something over. Zhao Chongyun reached out and caught it, and found it was two chocolate pies.

Xie Qingfei said: "Everyone has gone through this, it's normal to feel uncomfortable. Don't think that Xi Ming enjoys everything he eats now, in fact, he was also choked up when he first went to the scene. You didn't graduate from a police academy, so you're mentally strong for not having nightmares."
Zhao Chongyun whispered, "I did it."
Xie Qingfei: "..."

Xi Ming slurped his tofu pudding and said incoherently, "It's normal to have nightmares, but I tell you, as long as you think that you will seek justice for the deceased and not let her die in such an unclear way, the discomfort will be nothing. No matter how scary a corpse is, can it be scarier than a living person?"
Xie Qingfei smiled: "Oh, your ideological awareness is very high now..."
Xi Ming chuckled and said, "It's all because of Master's good influence."

Zhao Chongyun tore open the packaging of the chocolate pie and tried his best not to recall the scene at the crime scene yesterday. Instead, he thought of the several interrogations of Zhang Yuheng. The more he thought about it, the angrier he became. His teeth were itching, so he chewed the chocolate pie as if it were Zhang Yuheng. It surprisingly tasted not bad.
The hunger he had left behind came back, and after finishing the two pies he was still not satisfied, but he was too embarrassed to ask for more. Unexpectedly, Xie Qingfei seemed to have expected this, and handed him two fried dough sticks: "Here, eat them while they're hot."
Zhao Chongyun pursed his lips and said, "Thank you."
He swallowed slowly, peeking at Xie Qingfei through the rearview mirror, and asked, "Captain Xie, you didn't rest all night, aren't you tired?" Xie Qingfei's eyes were indeed a little bloodshot, but her spirit was not affected by staying up late at all. She was used to being busy, and she felt uncomfortable when she was idle. She was the kind of person who was particularly excited when she encountered a case. Moreover, the search and evidence collection within 24 hours after the incident was the most critical. The longer the time was delayed, the more clues would be lost, which was obviously not what the police officers wanted to see.

Hearing him mention this, Xie Qingfei's first reaction was to remember that he didn't care about the people around him. He also looked at him in the mirror and said, "You slept in the police station last night. Didn't you get enough rest? How about I take you home later, Xi and I..."
"No need." Zhao Chongyun refused coldly, turned his head away so that she wouldn't see his expression, and said sullenly, "I don't feel tired at all."
It sounded like he was throwing a tantrum, and Xie Qingfei was a little confused.

"Why doesn't anyone care about me?" Xi Ming, holding a fried dough stick in his mouth, looked at his phone and tried unsatisfactorily to attract attention for himself.
Xie Qingfei asked: "Who are you?"
He immediately made a hurt expression, reached out to wipe away his non-existent tears, then lowered his head and continued typing.

After a moment, he raised his eyebrows and said, "Big Mouth said he found the cigarette butt."
Xie Qingfei tilted his head: "How is it?"
"It was found in the trash can at the west entrance of the first floor. It has been sent for testing and the results are expected to be available in about 4 hours. However, there was no blood on the toilet paper that wrapped the cigarette butt when it was found. It was just an unused piece of paper. Maybe the tissue used to wipe the blood was disposed of separately. Why? I guess the two things belong to different DNA. The owner of the blood is not the owner of the cigarette butt. Zhang Yuheng admitted that he lost the cigarette butt, so the blood can only be left by Wang Shuang." Xi Ming fluently stated his judgment, lowered his head to glance at the information, and said, "The technical colleagues also made a new discovery on the air conditioner outdoor unit bracket. There are obvious traces of fingernails scratching on the side of the square tube against the wall. It looks like a word."
Zhao Chongyun immediately came to the front row and asked, "Is this the message left by the deceased before his death?"

Xi Ming enlarged the picture, and the three of them took a closer look. Zhao Chongyun frowned: "Is it... a 'jade'?"
Xie Qingfei: "It could also be a 'king'."

The conjecture was gradually verified. Xie Qingfei said, "The reason why Zhang Yuheng is considered the first suspect is that he was the last person to enter the deceased's ward, and the time coincided with the moment when the deceased fell from the building. But what if the deceased was not pushed out of the window and fell at the same time? When her body was thrown out of the window, she grabbed the bracket because of her desire to survive, and she was hanging in the air only by the strength of her arms. The murderer thought she fell, so he hastily cleaned up the scene and left. It was at this time that the deceased left a clue to the murderer's identity. Then Zhang Yuheng came, and just as he entered the room, the deceased was exhausted and let go, and eventually fell to her death."

Xi Ming said: "And the person who saw the deceased before Zhang Yuheng was..."
The three of them said in unison: "Wang Shuang."

"No wonder there was a two-minute time difference. It turned out that the deceased did not fall down the building immediately."

Zhao Chongyun was puzzled again: "Didn't she take the opportunity to call for help?"
Xi Ming rolled his eyes immediately: "Brother, the murderer is standing by the window. Do you think she will be rescued or kicked if she shouts for help? Zhang Yan is not a fool. Instead of shouting for nothing, she should leave some clues for the police while she is still breathing."
"When someone you trust murders you, all your feelings will turn into hatred. It's hopeless to expect the other person to have a change of heart in this situation." Xie Qingfei said, "Besides, being hung up with your hands tied up would be considered torture in ancient times. Zhang Yan had to hold on to the railing with her arms while carrying a big belly. If it weren't for her strong willpower, she would have been forced to leave some clues to avenge herself. This would have been almost impossible."

If I put myself in her shoes at that time, I would feel extremely desperate.

Xi Ming said angrily: "Let's go over there now and see whether this bastard is a human or a ghost!"

Seeing that he looked very excited even though his face was covered with dark circles, Xie Qingfei tried to ease the atmosphere: "You look so excited. You didn't get much rest last night. Did you want to solve the case quickly so you can go back and spend the weekend with your girlfriend?"
When this was mentioned, Xi Ming curled his lips and said resentfully: "Master, you really don't care about me at all. We have broken up for a long time. Not to mention that today is Saturday, even Valentine's Day has nothing to do with me."
Xie Qingfei asked in surprise: "Why did you break up?"
"She said I was too naive and that she couldn't see a future with me." Xi Ming said listlessly, "How am I naive?"
After saying that, he turned around and asked Zhao Chongyun, "Do you think I am childish?"
Zhao Chongyun was secretly yawning, but when he heard this, he quickly stopped yawning and said, "It's actually okay."
"Don't say anything. It's unnecessary to ask you." Xi Ming said, "But I do need to go home early today. My brother is sick."

Xie Qingfei paused: "What happened to him?"
Xi Ming said: "Just like Xiao Zhao, he feels sick and wants to vomit when he sees food. He has a poor appetite and feels dizzy. It doesn't make sense."
Xie Qingfei thought of last night's situation and asked, "Could it be gastroenteritis?"
"I asked him, and he said no, it might be due to stranger fear or some other symptom. I don't understand, and I never thought he had social anxiety before." Xi Ming said, "Well, he's a doctor anyway, so he must know what's going on. I thought I'd buy him some of his favorite food on the way home from get off work and bring it back to see if it can make him feel better."

Xie Qingfei's mind went blank for a second, and she suddenly realized that she had no idea what Wei Cheng liked to eat.

"Master, don't worry. Maybe he just vomited at work. Young people, how many of them don't go crazy at work? This is normal." Xi Ming glanced at Xie Qingfei and said.
"I'm not worried." Xie Qingfei stuffed all the garbage into the bag and started the car. "What can happen to a big guy like him?"
"I'll drive, I'll drive," Xi Ming offered. "How can the master drive while the apprentice sits back and relax? Don't you think so, Xiao Zhao?"
Zhao Chongyun: “…”
What a childish revenge this is. No wonder the girl dumped him.

Xie Qingfei did not insist and changed seats with Xi Ming.

Because they were all close to Wei Cheng, they naturally did not believe Zhang Yuheng's words that he was jealous of his good life and wanted to murder him to ruin his reputation. But apart from personal relationships, Zhang Yuheng's words were also one of the clues they had to pursue. Even though Wei Cheng had an alibi, he and Zhang Yuheng both admitted that he unilaterally broke the appointment and canceled the lunch schedule they had originally planned. He did not explain clearly what made him suddenly change his mind.

Could it be that he suddenly became curious about the birthing experience and wanted to try it right away without even eating? Who in his family was pregnant that could make him so worried?
Xie Qingfei racked her brains but couldn't figure it out. All she could think about was Wei Cheng's pale face last night and his hesitant look when he faced her. For some reason, she leaned slightly towards the window and quietly opened the search engine and typed in: [What causes nausea and vomiting? ]
The first message that pops up is: [Don’t panic if you experience these symptoms in early pregnancy, pregnant women should pay attention to…]
Xie Qingfei was startled and his phone fell onto the seat with a bang.
Xi Ming asked, "What's wrong?"
"It's okay." She picked up the phone, closed the search window, and sat down in shock.

Gastroenteritis is more scientific.
