Silver Snow Line [Criminal Investigation]

"It's a small account bought from a website that resells accounts. The email address and phone number bound to it are both fake." Dai Lin found the person who chatted with Du Manhe based on her Weibo, but did not find any useful information.

"Du Manhe is quite bold. She can even chat with people like this?" Lu Shaohui glanced at the account homepage and expressed his incomprehension.

Wei Cheng said: "Because her purpose was not to make friends, she just wanted to have a channel to vent, so it didn't matter who the other party was. Not to mention that this netizen has been comforting her and empathizing with her, making her feel understood, and the emotional floodgates naturally opened up."

While Du Manhe was still trying to communicate with Kang Wenxia and deal with the problem, she couldn't say that she hoped she would die, because the education she had received and her own cultivation would not allow her to treat others like this. She despised verbal abuse and cursing. She couldn't complain in her life, and her family didn't agree with her way of dealing with it for the sake of so-called neighborhood harmony. She didn't want to be suffocated, so she could only vent her dissatisfaction with Kang Wenxia on the Internet.

Xi Ming said: "It takes fifteen minutes to ride an electric bike from Jincheng Jiayuan to Tianning Primary School. Du Manhe came home from get off work yesterday before six o'clock. She wrote a letter and posted it on Kang Wenxia's door. The two did not meet during this period. Then she started to prepare dinner for the family. After cooking dinner, she had to feed the children first, and she could eat after the children had eaten. She also had to clean the table, wash the dishes, and wash the dirty clothes that the family members had changed. She had to sweep and mop the floor during the half hour when the washing machine was running. After finishing these things and hanging the clothes, it was already past nine o'clock. She had to wash the children again and coax them to sleep, and then she had time to do her own things. Because there was no noise from upstairs last night, which was rare, she rested earlier than usual, so from the perspective of the time of committing the crime, she could not spare the time to do it. If she did not complete a process, she would be nagged to death by her family. The elevator surveillance did not capture her going upstairs, but it was useless for her family to testify for her. What if she went up the stairs?"

Dai Lin frowned when she heard this: "There are so many people in her family, and she does all the work by herself?"
"Ah. Otherwise she could spend a day with me." Xi Ming looked at Wei Cheng.
Wei Cheng explained, "She feels that staying at the police station is more relaxing than staying at home. She finally has a reason that no one else can interfere with that allows her to temporarily get away from her family affairs. She doesn't want to go back after just a few words."
Dai Lin immediately felt sympathy for Du Manhe: "I understand why she was so upset. She was already tired enough. Sleep is the most basic need of human beings. If this cannot be met, life is indeed worse than death."
Xi Ming shook his head in disapproval: "That doesn't mean you can kill people."

"However, considering that both bodies have serial numbers and they look like they were killed by the same weapon, it is very likely that the murderer is the same person." Lu Shaohui printed out the image of the old man's wounds. "Both bodies were found naked, and the cause of death was related to water. This can't be a coincidence."
Xie Qingfei hesitated for a moment and asked, "How long has the old man been dead? Has the forensic doctor made a judgment?"
Lv Shaohui replied: "According to TADS and the cumulative daily method, the time of death is about five days."
"Then Du Manhe didn't kill the old man," Xie Qingfei said, "She was on a business trip five days ago. Besides, Kang Wenxia and the old man are both taller than her. Let's not talk about the former for now. It's difficult for her to handle the situation where the old man needs to be disposed of."
Du Manhe is barely 1.6 meters tall and rather thin. She has been in poor spirits for days, so it is not realistic for her to carry an elderly person taller than her.
Xi Ming held his chin and yawned: "If I could know the detailed information of the master, I could see if there is any connection between them. Unfortunately, I still can't confirm the identity of the master."
Lu Shaohui sighed: "Then our only direction at the moment is this netizen."

"This netizen said that he saw Du Manhe's Weibo in the same city, and said that he had the same problem as her. He took the opportunity to ask her about the structure of the residential complex, the year of delivery, the floor situation, and other information. On the surface, his purpose was to analyze the objective factors that could not eliminate the noise for her. In fact, since they were in the same city, the few things Du Manhe said were enough to infer which residential complex she lived in. In addition, Du Manhe would usually post some photos of her daily life on Weibo, and the buildings in the photos could also help him determine the location."

It was Xie Qingfei himself. After reading the community information that Du Manhe inadvertently revealed, combined with the building locations in the pictures accompanying her blog post, he was able to deduce in detail in his mind the route she took every day, and even provide a few shortcuts.

Xi Ming got goosebumps when she said that: "So, maybe they have met in real life, but Du Manhe doesn't know?"

After the meeting, Xie Qingfei returned to the office to visit Comrade "Zhao Daiyu".

Zhao Chongyun drank two bottles of hot water before his face regained color. It was not cold in the room, so he wrapped himself in a blanket like a silkworm. He felt embarrassed when he saw her coming, and immediately said, "I'm sorry, Master. I will go back to help when I'm ready."
"Let's talk about tomorrow tomorrow," Xie Qingfei didn't rush him. Seeing his pitiful appearance, he couldn't help but tease him, "How many days do you plan to skip meals this time?"
Zhao Chongyun turned his eyes away awkwardly and whispered, "I'm not that weak anymore."
Xie Qingfei chuckled and helped him pull up the blanket that had slipped off his shoulders.

Zhao Chongyun held his breath immediately, and caught a glimpse of her slender fingertips passing by his ear. An indescribable fragrance seemed to waft from her sleeves and penetrate into his nose.
Because she was going to school with Jiangjiang today, she put on some light makeup, and although her hair was just tied up with a pen, it was not messy at all. Zhao Chongyun didn't know if all women had the ability to make a good-looking hairstyle at will. He felt that Master looked good no matter what. When she was at Zhuque Lake, she looked even better with her long hair loose. Her sharpness seemed to be covered by gentleness, and she was no longer so unattainable.
Master is so kind. Zhao Chongyun's mind was filled with this thought.

By the time he came to his senses, Xie Qingfei had already left.

Xi Ming pushed open the door and saw his silly expression. Then he thought of the person he had just met in the corridor, and his facial features twisted into a frown.
He coughed loudly, and Zhao Chongyun sat up straight with a start. He relaxed when he saw it was him.
"Why are you so startled?" Zhao Chongyun rubbed his face and drank all the remaining water in the cup.
Xi Ming fell on the chair, looked up to the sky and sighed: "This is extremely treasonous."
Zhao Chongyun quietly packed up his things and prepared to go home. When he passed by his desk, he was greeted with another sentence: "Unfortunate Master." He suppressed his urge to glare at him, and strode away with a "humph".

The next day.
Xie Qingfei and Lu Shaohui came to Jincheng Jiayuan again.

Du Manhe and her husband both went to work, leaving only an elderly couple and her one-year-old son at home.
The little boy couldn't walk yet, and when he saw a stranger, he stared at him with the same eyes as his mother. Lu Shaohui teased him, but he didn't cry. When the two elders saw the police ID, they looked at each other and waited by the side in a very polite manner.

Xie Qingfei looked around the living room and went to the balcony to check.

Because the two floors downstairs are shops, Du Manhe's house has a large outdoor terrace, which is very convenient for drying clothes on weekdays, and you can also take a walk to digest food after meals.

Lu Shaohui said a few words to the two elders and came out to look for her. It was so windy outside that he wanted to pull the collar of his jacket down to his nostrils. He said, "This apartment is great. It's like having a yard."
"Yes, it's good, and the height is suitable," Xie Qingfei leaned over the fence to take a look, "A person with better skills can climb up without a ladder."
Lu Shaohui immediately perked up and looked down along her line of sight: "As long as we climb up to the third-floor terrace, we can easily climb through the fourth-floor window and enter Kang Wenxia's home."

"what is this?"

Lu Shaohui noticed some green paint smeared around the wall and went over to take a few photos.
Xie Qingfei squatted down beside him, bent down to sniff, and confirmed: "Waterproof paint, it looks like it was just applied recently, this direction is..."
She glanced at the balcony on the fourth floor again and said, "Ask the property management what's going on."

Lu Shaohui made a phone call and got an answer a few minutes later.

"A few days ago, the shop downstairs reported a water leak upstairs. The property management sent someone to check and said it was a problem with the drainage pipe and ground leakage. They arranged for someone to go to 403 to re-do a layer of waterproofing and brush the balcony floor." "When was it brushed?"

"Yesterday at noon," Lv Shaohui finally realized, "those green paint on the ground were the footprints and kick marks left by the suspect when he stepped on the balcony floor?"
"Then this person should not be a resident of Jincheng Jiayuan, otherwise he should not be able to see the messages in the owner group." Xie Qingfei said, "The vision is blocked at night, and he probably doesn't know that he left footprints."

Based on the shape of the traces, it is basically possible to tell the direction in which the suspect climbed over. He did not leave any footprints when he came, and only when he was trying to escape from the scene along the same route did he accidentally expose his footprints because of the residue of waterproof coating.

"Male, between 1.80 and 1.85 meters tall, in his thirties, in good physical condition, wearing herringbone sneakers. His right leg came out first during the leap, so he might be left-handed." Xie Qingfei took out a tape measure and measured it, then said concisely, "He also limps a bit."
Lu Shaohui was surprised and said, "He can climb over the wall even though he is lame. His physical fitness is really good."

"It means he got injured later in life. Maybe he was a manual laborer before, but had to change his career because of the leg injury."

Kang Wenxia's house did not have anti-theft railings installed. The balcony had a floor-to-ceiling glass swing door made by knocking down the window frames. Xie Qingfei found an angle and jumped up from the wall. Without much effort, he jumped into the fourth-floor balcony. He turned the door handle and found that it was locked.
Lu Shaohui tilted his head and asked, "Did you find anything?"
It was a cloudy day today, and the light was not good. Xie Qingfei turned on the flashlight and shone it towards the keyhole, then said to him, "Come up and take a look too. There should be soap around the keyhole."
"Soap?"
Lu Shaohui climbed up holding the railing. He first saw a green patch on the ground, and then he looked at the keyhole.

"Ten or twenty years ago, people often used pencil leads, chewing gum, soap and other things to open locks. This guy was quite a technician." He carefully removed the white soap particles attached to the locks. "There were many cases of burglary and murder at that time. Now the times are different. At first glance, it feels like a Renaissance."
"But no valuables were stolen from Kang Wenxia's home, and the medical examiner also said she had not been violated before her death. They wanted her life, not money or sex."

Xie Qingfei took out a piece of wire from somewhere, inserted it into the keyhole and turned it twice, and the door opened with a "click".

"Didn't Dai Lin say that Kang Wenxia was just an internet troll? Maybe someone who was trolled by her holds a grudge and has found her home address and is coming to her house for revenge."
Lu Shaohui followed her into the door and couldn't help but say, "Teach me how to open it later."
"Okay, I learned this from my colleagues when I was an intern, but it only works for ordinary pin tumbler locks."

Xie Qingfei looked around the living room. It was far from tidy. Clothes were hung on the backs of the sofas, and there were black spots on the floor caused by food dripping and being stepped on.
She opened the shoe cabinet in front of the house and took a look, and found that the three-layer shoe rack was filled with high heels, some of which were brand new and had never been worn. The invoice in the shoe box also showed that they were purchased recently.

Xie Qingfei tapped his hard heel and asked, "Did Du Manhe say that Kang Wenxia makes a lot of noise when she walks every day?"
"Of course. Listening to the same sound for a long time will cause a mental breakdown." Lu Shaohui also understood something when he saw the pile of shoes. There was a trace of contempt in his eyes. "So it's really bad luck to meet a neighbor with no manners. You said that people have bought a house with great difficulty, and they can't move away just because of the noise. Where can they move to? They still have a lifetime mortgage on their shoulders."

Kang Wenxia was not short of shoes to wear. She bought so many high-heeled shoes after the downstairs residents complained that her house was too noisy. Her purpose was self-evident.

Xie Qingfei had never experienced this kind of trouble before, and asked curiously: "What is the reason for moving the tables, chairs and benches?"
"Captain Xie, do you know that your question can be listed as one of the top ten unsolved mysteries in the world? God knows what these people are doing upstairs all day long." Lu Shaohui felt like he saw a weirdo who was ignorant of the sufferings of the world. He was so envious that he was a little jealous.
Xie Qingfei glanced at him and said, "You also have a deep understanding of this?"
"My upstairs was also a bad guy at first. It was useless to talk to them nicely. I should have called the police, but I'm a policeman myself and it would be embarrassing to tell anyone about it." Lu Shaohui said proudly, "But the mountain people had their own clever tricks, and I finally dealt with them."

Xie Qingfei walked to the island counter, where there was a row of wine glass racks. Her eyes rested on one of the cups and she put on the gloves and took it off.

Lu Shaohui didn't notice and continued, "But the method I used is more vulgar. It's okay for someone who lives alone to say something, but people like Du Manhe who have a family have too many weaknesses. Even if they can ignore other people's opinions, they still have to worry about whether their family will be retaliated against. So honest people are at the bottom of society. When facing a bully like Kang Wenxia, ​​there is no other way but to swallow their anger."

"It seems that this suspect is 'doing justice for the heavens'." Xie Qingfei turned the rim of the cup, looked at the sink again, and said, "Send someone to test whether there is any abnormal substance in the sewer."
Lu Shaohui was surprised: "Okay. What did you find out?"
Xie Qingfei looked up at the row of foreign wines in the cupboard and raised the glass in his hand: "She didn't prefer any one cup, but the water stains show that this one in my hand was the last one she used."
Lu Shaohui squinted his eyes and looked at it carefully for a while, then asked, "Why are there still cracks?"
Xie Qingfei: "Silicon dioxide will be destroyed by some highly corrosive liquids."

Lu Shaohui was busy making a phone call while Xie Qingfei continued to walk towards the bathroom where the body was found.

He had just finished explaining the situation when another call came in. The person on the other end finished speaking hurriedly, and Xie Qingfei saw that his expression gradually became solemn.
"what happened?"
Lu Shaohui: "A new death has been discovered."
Xie Qingfei raised his eyebrows slightly: "Number one?"
"No," Lu Shaohui said with an unpleasant expression, "This time it's No. 4."
"Drowned?"
Lv Shaohui shook his head again: "The deceased was a 19-year-old boy. His body was hung on the beam of the balcony at home. He was also naked. His number was engraved on his back and his eyes were cut with an 'X'."

After that, he asked in confusion: "There is also an '×' on the old man's mouth. I originally thought that the deceased wanted to destroy his face so that we could not find out his identity information, but with this boy, it is obviously a deliberate mark. But why is there nothing on Kang Wenxia except the number?"

Xie Qingfei: "Serial killers want to leave their mark at the scene, and they don't necessarily have to do it on the body of the deceased."
Lu Shaohui was in a dilemma: "But this place has been cleaned by Kang Wenxia's stepmother, and the marks have been erased long ago."
"The visible ones can be wiped off, but what about the invisible ones?"
Xie Qingfei rolled the soap residue on his fingertips, walked to the sink, turned on the faucet to hot water, and soon the hot air dispelled the chill in the bathroom. The steam continued to rise, and soon a thin layer of mist covered the mirror.

Lu Shaohui walked closer and found that a huge "×" was gradually emerging on the originally clean mirror surface.
