Qi Yuan raised his hand and pointed, saying: "I'm looking at the gas pipe outside the wall, the distribution of sewer pipes, and the air conditioner outside."

After a pause, he continued: "This building has seven floors. The victim lives on the sixth floor. There is no anti-theft net installed on the site. It is not difficult to get down from the roof, but the path needs to be carefully planned. I have just studied this issue.

"

"It's rare that you did something serious." Su Ping said, and then asked: "What's the result?"

"What do you mean it's hard for me to do my job?" Qi Yuan was dissatisfied and retorted, but he immediately continued: "The sewer pipes are made of plastic pipes. Although the strength should be up to standard, they always make people feel uneasy, so I want to be suspicious.

People should come down through the gas pipe and use the outdoor unit of the air conditioner as a foothold.

Of course, if the suspect is brave enough and walks into the sewer pipe, it will be much more convenient and he can just slip down."

After a pause, he continued: "If conditions permit, I think we can check these two paths. 'Working at heights' is no better than others, especially for people who don't often work at heights. No matter how courageous they are, their heartbeats will inevitably accelerate and their muscles will tense up."

It may leave many valuable clues."

Su Ping nodded in agreement, and then added: "But after you have finished speaking, the trace inspection has already carefully inspected the exterior walls and exterior pipes. After all, they have solved more than just cases of breaking into homes through windows at high altitudes.

One thing or two, this kind of mistake will never be made."

Qi Yuan had no choice but to take back his hand and said, "Have you discovered anything?"

"Nothing." Xun Mu continued: "The survey results show that he did not use these external pipes to leave the scene. He probably used a professional climbing rope to rappel down and leave."

Qi Yuan scratched his head: "This is troublesome, it's not leaking."

Then he looked at Su Ping and said, "Since I've checked everything, why did Team Su ask me to talk?"

"Give you a chance to use your brain." Su Ping said, then turned around: "Go back first, there is no need to waste time, first determine the identity of the victim."

Xun Mu and Qi Yuan nodded one after another and returned to the detachment with him.

…

As soon as they entered the detachment building, the three of them saw Brother Song and Fang Chang escorting Ning Huayin out.

"Captain Xun, Captain Su, are planning to find you two." Brother Song said hello, then looked at Ning Huayin and said: "Ms. Ning..."

"It's okay, there's no need to send him off, I'll go back by myself." Ning Huayin shook his head, with a tired look on his face, and said, "I'm looking for a hotel nearby to stay temporarily. If you have anything to do, please contact me directly. I should be there recently."

All convenient.”

"Thank you for your understanding and cooperation." Brother Song smiled, and then said: "Please pay attention to safety recently. If you have any questions or think of any clues, you can contact us at any time."

Ning Hua hummed, turned around and walked out of the detachment building.

Su Ping withdrew his gaze, pinched his chin, nodded, and then looked at Brother Song and asked, "What's the matter?"

"Go to my office and talk." Xun Mu suggested with a wave of his hand, and several people nodded.

Soon after walking to Xun Mu's office, Brother Song couldn't wait to take out the cigarette and spread it around. Then he lit one and took two beautiful puffs. It was obvious that he was having a hard time holding it in.

Then he said: "It's mainly about Ning Huayin. Fang Chang and I conducted a relatively systematic inquiry about her."

"Well, what next? Are there any clues?" Su Ping asked.

"Uh, no." Brother Song shook his head and said, "But we can basically further confirm that she is not suspected of committing a crime."

"Hasn't her suspicion of committing the crime been eliminated early on?" Su Ping rolled his eyes: "After all, she has a perfect alibi. And if she paid someone to kill someone, it is impossible to let the murderer commit the crime in her own home."

Xun Mu then continued: "But since the murderer chose her home as the place to commit the murder, he might have some connection with her. Xiaosong, please continue talking."

After a pause, he said before Brother Song spoke again: "By the way, does she know the victim?"

"I can't recognize it. After all, it's like that. I'm afraid the victim's parents may not be able to recognize it." Brother Song shook his head and finally added:

"She didn't take a close look at the body. As for the head, I showed her a photo, but the head was completely unrecognizable. The murderer chopped several times on the face, threw it into a pot and boiled it for a long time. It was not visible at all.

We can only hope that the face can be restored and that the restored face will be close to her original appearance."

Su Ping clicked his tongue: "You want to come to us deliberately for this matter?"

Xun Mu elbowed him, glanced at him sideways, then looked at Brother Song and said, "Don't be in a hurry and speak slowly."

"Yes." Brother Song nodded and said, "Ning Huayin herself has simple interpersonal relationships and is not a native of Yuqiao. She is from a mountain city. After graduation, she came to our province to take exams all over the place and finally got here."

"That is to say..." Su Ping nodded: "She doesn't know many people here?"

"There is a roommate who is from Yuqiao." Brother Song said: "There are also a few friends who play gangster together, but other than that, I have no relatives."

After a pause, he added: "She just rented this house three and a half months ago.

She had better luck during the exam. She knew most of the questions she got, and the accuracy of a few questions was also very high. Her condition was as good as ever before...

In short, after the written test results came out, she found that her score was extremely high, and there were three recruitment positions. Our Yuqiao test scores were few, and the possibility of landing was very high, so she rented a house directly and found someone to change it on the same day.

Lock cylinder."

"Oh?" Su Ping frowned and said, "After renting a house for a few days, he traveled around the country and just came back today? Isn't this three months' rent for nothing? Do you have money to burn?"

"She has been here for nearly three months." Brother Song said: "After the results come out, there will be a professional skills test for teachers, which is a trial lecture or lecture. After that, there will be a review of the information, a structured interview, a political review, etc.

Yes, it’s all very troublesome and complicated.”

Xun Mu nodded: "If you are taking the exam in a different place, it is more convenient to rent a house first when you are sure."

"That's what she thought." Brother Song continued: "After the political review materials were submitted, nothing happened to her, so she started to go out and travel. It wasn't until the list of candidates to be recruited was announced and it was basically confirmed that she would go ashore, then she returned to Yuqiao."

Su Ping pinched his chin: "So, am I too sensitive?"

"You've never taken the public examination in another place, so it's normal." Xun Mu shrugged.

"I still feel something is wrong." Su Ping shook his head, and then added: "Even if it is reasonable to rent a house in advance, I still feel that there is still a problem."

"What's the point of the Internet cafe being black?" Qi Yuan asked immediately, and then said: "To be honest, I still can't understand why I have been out playing for more than twenty days. Logically speaking, I should be exhausted by now, so how can I still have the energy and energy to go out?

Is the Internet cafe open all night?”

"Indeed." Su Ping answered: "At first I thought she was full of energy, but now the more I think about it, the more something is wrong... Traveling seems to be a way to relax, but in fact it is very tiring. Even if you travel independently, it is just as hard. She doesn't think about it when she comes back.

Instead of going home first, you drag your suitcase and go to an Internet cafe to spend the whole night?"

Several people looked at each other and shook their heads.

Su Ping looked at Brother Song and asked, "Have you asked her about this?"

"No." Brother Song shook his head and said, "I didn't think much about it, because the victim had been dead for several days, and she hadn't been in Yuqiao for more than 20 days. Besides, as Captain Su said, you can't pay someone to kill someone.

Choosing the house he rented as the scene, the murderer didn't have to go through such trouble...

In addition, her interpersonal relationships are very simple, and she has never offended anyone, let alone made enemies. All logic shows that she does not have the conditions and motives to commit crimes, so we did not think too much about this aspect. She said that she stayed in the Internet cafe all night

, and the Internet cafe has monitoring systems that we can check, and this problem has been solved.”

Su Ping thought for a moment, took out his notebook and immediately wrote down this clue.

Then she looked at Brother Song and asked unwillingly: "Didn't Ning Huayin provide any clues?"

Brother Song shook his head: "She really couldn't provide any clues about this case, but she suspected that she seemed to be being followed recently."

"Huh?" Xun Mu said, "What's going on? Being followed?"

"She was not sure, and she didn't find any clues, but she just had this feeling." Song Ge said: "In addition, there was a murder in her home, which made her even more frightened and worried that someone was going to harm her, so she wanted to ask for help.

We ask for help."

After a pause, Brother Song shook his head again and said: "Our police force is quite tight. Although protecting the people is one of our responsibilities, it is impossible to send someone to protect her because of some unfounded suspicions, right?"

Xun Mu immediately asked: "So you asked her to pay attention to her safety recently?"

"Yeah." Brother Song nodded and said, "After all, a murder just happened at her home, and she said she was being followed - I forgot to mention that she also called the police when she was traveling, but was not taken seriously by her local colleagues.

The case will not be filed. I will seek confirmation from my colleagues at the local police station later.

If she really reported the crime and really felt this way, it would be too much of a coincidence. Maybe someone was really following her. In other words, I felt a little uneasy and wanted to ask what should I do.

manage."

Su Ping crossed his arms, leaned back, and said softly: "The most appropriate and lowest-cost way is to let her stay in our detachment for a few days. There is no need to send someone to protect her. I don't believe anyone else dares to touch her."

Enter the detachment and kill people."

Xun Mu glanced at him sideways: "Don't talk so eloquently. Have you forgotten Wu Qingguo? He dared to sneak into the detachment and go to the forensic department in the basement to see the corpse."

Su Ping choked and snorted angrily.

Brother Song thought for a while and asked, "Then where will she sleep?"

"Let's see which female colleague is on vacation. Let's free up the bed." Su Ping said, "Or if she doesn't mind, she can sleep in my lounge. If I have to be on duty, I'll just stay in the office for two nights."

It’s really not possible to buy her a bed and let her use the floor in the conference room? Anyway, she should have toiletries, chargers and other things, so it doesn’t matter if she stays for a few days.”

Brother Song hesitated for a while, then looked at Xun Mu and asked: "Captain Xun, is this in compliance with the rules?"

"Your Captain Su has already spoken, what else is wrong with the rules?" Xun Mu chuckled and said, "You can inform her, if she doesn't mind, I don't have any objection.

But you can’t wander around on weekdays, just stay in the conference room and don’t affect our work, otherwise don’t blame me for chasing people away.”

After a pause, he looked at Su Ping again: "I have no objection to vacating the duty room, but it must be sorted out before it is vacated. Case files and other things must not be left in it."

"I know." Su Ping said, and then he spread his hands and said: "Anyway, you have to pay attention to her and don't let her wander around. Allowing her to 'live' in is already the greatest concession."

Brother Song nodded lightly and said, "Then I'll call her now."
