The first suspect didn't look like she was awake when she was arraigned, and judging from her face, she should have slept badly.

"Do you know the victim?"

"It doesn't have much to do with each other, but I know she's a person who lives here."

"Do you know who the person in this building usually has the closest relationship with the victim?"

"It's not very clear, she's not very popular, and everyone has been talking about her stealing things recently."

"Did you hear an unusual noise in the victim's house this morning?"

"I didn't hear you."

"What were you doing in the morning?"

"Sleeping, sleeping since the night shift."

Xu Tian on the side observed that there were some residual cosmetics on the suspect's face that had not been washed, and the suspect's clothes were relatively sloppy, not wanting to wear pajamas like the other two suspects, the suspect was wearing a shirt that had been wrinkled.

"Do you sleep without taking off your clothes?"

"I was so tired that I went straight to sleep when I came back."

"Didn't do anything else?"

"Wash your face, go to the toilet, and then go straight to sleep."

"Do you usually wear earplugs when you sleep?"

"I only started recently, because I have been working the night shift for three weeks, I have a nervous breakdown, and I can't sleep during the day, so I brought earplugs."

"Then you haven't heard anything outside all day?"

"I don't know either, because sleeping with earplugs doesn't mean I can't hear anything, but the sound insulation is still very good, and I've been sleeping."

"Do you think about it, did you hear anything on the way to sleep?"

"Not really, and if you don't believe me, I can't help it."

Lao Chen felt that he would not gain anything if he continued to ask, so he summoned the food delivery woman who was waiting outside the car.

The woman who delivered the food was dressed in a greasy outfit, especially the apron she wore in front of her, which looked like it hadn't been washed in months.

"When you came to deliver food today, was there anyone else in the victim's house?"

"I didn't pay attention, and after handing her the food, I turned around and went downstairs."

"Did you make any noise when you went upstairs or downstairs? For example, the steps are fast, very heavy, and so on. ”

"As soon as you say that, I remembered that I did walk faster when I went upstairs, but after handing the meal to the customer, I remembered that there was a nervous breakdown girl downstairs who was not sleeping well, so I went downstairs with a light step."

"Okay, it's okay, you can go back." Xu Tian said.

In Lao Chen's surprised eyes, the woman delivering the meal was released.

"You kid see the clue in this?" Lao Chen asked.

"I already expected the footsteps of one upstairs and one downstairs, one of them must have been sent by the food delivery woman, I just want to hear her say why there is only one upstairs or downstairs sound, so according to the description of the food delivery woman just now, it is already obvious that among the two suspects who heard the sound of going upstairs and going downstairs, one of them is the murderer." Xu Tian said.

"The woman who delivered the food said that she only made the sound of going upstairs, so the second suspect who heard the sound of going downstairs was the murderer, right?" Lao Chen said.

"It couldn't be more obvious, because the murderer wanted to shirk responsibility, so it confused our judgment, and the second suspect who was the same age as the victim was the murderer." Xu Tian said.

"I suggest that the murderer not be arrested now, we need to find out why the murderer did this, and whether this case is related to the ruling Tai Sui has not yet been clarified." Lao Chen said.

"There's only one way to find out if this case has anything to do with Zhinian Tai Sui, but I don't think you will agree." Xu Tian said.

"You're not going to want to do something dangerous again, are you?" Lao Chen asked.

"Is there any other way than to let the murderer go and put him under surveillance?" Xu Tian asked.

"I will never agree to do this, the reason why I just said that it is best not to arrest the murderer for the time being, but I don't want to do this, I want you to help me consult, how to solve the case in the best way." Lao Chen said.

"Or you can ask the murderer what your relationship is with Zhi Nian Tai Sui." Xu Tian said.

"Aren't you raising a bar with me?" Lao Chen said with a gloomy face.

"Then it is the safest way to bring the murderer back to the police station and find a way while interrogating, but in this way, the chances of us returning empty-handed are too great." Xu Tian said.

"No matter what, I can't go against the principle of handling the case, and there is no other way to go except this method." Lao Chen said.

"I'll give you the best advice again, the saying that you can catch big fish with a long line will never go out of style." Xu Tian said.

"You don't need to say it, I won't do that kind of dangerous thing, if the murderer causes harm to the people during the release period, then our sins will be great." Lao Chen said.

Xu Tian couldn't say that Lao Chen couldn't do it, so he had to watch Lao Chen bring the murderer back to the police station, this time there would be no breakthrough, it was originally the best opportunity to get close to the ruling Tai Sui, and it came to naught.

After Lao Chen left, Xu Tian followed Dr. Lin back to the nearby police station, and the two deliberately found a room where no one was there to discuss the case.

"Lao Chen's approach is really infuriating, if he fails this time, I don't know what year and month I will have to wait for the opportunity." Dr. Lim complained.

"You can't blame Lao Chen completely, who made Lao Chen that kind of upright character! If Lao Chen was as smooth as we were, I'm afraid I wouldn't respect him so much. Xu Tian said.

"It's ridiculous, what's there to respect? Worse than useless. Dr. Lim said.

"You don't say that, Lao Chen, right? But then again, why didn't you say anything at the scene of the crime? Xu Tian asked.

"Is it useful for me to make a statement? You two solved the case so quickly, how can it be my turn? Dr. Lim said.

"But in the end, we didn't find out that the traffic accident had anything to do with the murder, could it be that we thought too much?" Xu Tian said.

"It's absolutely impossible, if you think about it with your arms, that serial car accident is not normal at all, how can there be so many trucks loaded with mobile phones at the same time? And they are all sent to the city? It's all the same brand of mobile phones, how can there be such a big sales? That's 12 trucks, how many mobile phones do you need? Dr. Lim said.

"If it is a conspiracy of Zhi Nian Tai Sui, then he has made a bloody investment, and the source of those mobile phones should be investigated soon, and this clue can also be used at that time." Xu Tian said.

"Don't be naïve, do you think Zhinian Tai Sui will be stupid enough for us to find clues from the source of the goods?" Dr. Lim said.
