"It's not difficult to find out who has been in contact with the victim today in this kind of densely populated illegal rental house, right?" Xu Tian asked.

"That's right, today is a working day, and since most of the people living upstairs are women, there is indeed something wrong with the landlord's illegal rental house, but in terms of guarding idle people, etc., the landlord is still quite responsible, according to the landlord's confession, from this morning to now, only the woman who delivered the food has entered the rental house, but the woman who delivered the food did not stay, and left in a hurry within a minute." Lao Chen said.

"If the victim's death is related to the heavy blow, the suspicion of the woman delivering the meal cannot be ruled out, but it is necessary to see what the results of the medical test are, and it would be good if the time of the victim's head was hit accurately." Xu Tian said.

"It was a new injury, and according to the degree of swelling of the scalp, it was preliminarily determined that the time when the victim was hit hard was this morning, so the possibility of a crime in the morning was ruled out." Lao Chen said.

"This is much easier, most of the victims had a conflict with the people inside this illegal building, and this case does not seem to have much to do with Zhi Nian Tai Sui." Xu Tian said.

"Let's do some further research! We can't let go of any case, the situation is very critical now, you should understand the reason, right? Lao Chen said.

"Then let's do a side investigation, all the people who are staying at home in this illegal building are suspects, including the woman who delivered the meal." Xu Tian said.

The police quickly searched the illegal building and found a total of three people who stayed in the rental house, and all of them were women.

The first suspect, a recent college graduate who works in a nearby electronics factory, slept at home because of her shift shifts, and looked sleepy-eyed when the police knocked on her door. The police asked her why she could sleep so soundly when it was so noisy outside, because the suspect had sponge earplugs in her ears.

The second suspect, a woman of the same age as the victim, worked in a nearby textile factory and stayed at home to sleep because of her shift shifts. When the police knocked on her door, the suspect was in good spirits, and she was still doing some foam on her hands and was washing clothes at home.

The third victim is a middle-aged woman about 40 years old, who has just come to the city to work as a housekeeper, but the suspect has been fired by the housekeeping company for stealing something from the employer's house, which is quite similar to the reason why the victim is unemployed, so the third victim was first summoned to the police car downstairs for questioning.

"Do you know the victim?" Lao Chen asked.

"Yes, I don't know it well, because I've only lived here for less than a month."

"Do you know what happened to the victim who lost his job?"

"Theft! Everyone in the building knows that everyone is talking about her behind her back. ”

"Did you see the victim this morning?"

"No, I haven't been out since morning."

"Why do you stay at home?"

"Because I don't have much to do these days, and I can't find a job as a housekeeper, when the rent is due, I will prepare to go back to my hometown for the New Year, and the tickets have been bought."

"So this morning, did you hear any quarrels in the victim's home? There are even sounds of hands-on fights? ”

"I really didn't pay attention to this, because there are usually a lot of people here who quarrel, so it's not uncommon to quarrel."

"If you heard a fight upstairs this morning, you should have an impression, right?"

"I wasn't really impressed, because I wasn't in a very good mood, and I was in bed all morning, and I fell asleep several times."

"You've spent all day at home like this?"

"So what else can I do? I have been blocked by the housekeeping company, and I will not do any other work, I plan to go home for the New Year after the rent expires in a few days, and go to other cities to find a job after the New Year. ”

"Why do you have to wait until the rent is due?"

"Because I paid a month's rent! It's a contract, and the landlord won't pay the check-out rent, so it's a waste if you don't live in! ”

"You and the victim's room are not far away, if there is any noise coming from the victim's room, you should be able to hear it, you can't deny that, right?"

"I really didn't hear anything, oh yes, I remember that it was almost noon and someone was hurrying upstairs."

"Do you remember?"

"Because I was sleeping soundly! I was in a worse mood after being woken up by the sound of going upstairs. ”

"Did you open the door to see who went upstairs?"

"No, I got up and drank a sip of water, then I fried a dish, and ate a bite of lunch on the leftover steamed buns from last night."

"Did you hear the guy coming upstairs coming down after that?"

"No, I just heard a sound of going upstairs, and then nothing happened, until it was very noisy outside, and I didn't know that the police were coming."

The following is an interview with the second suspect.

"Do you know the victim?"

"Yes, we also worked in the same factory, and then she was fired because her hands and feet were not clean."

"What was the reason for the expulsion? I mean the specific reasons. ”

"She always stole some tape, screws and other small objects, and over time she was found out, and then she was fired."

"Do you usually have contact with the victim?"

"I haven't had much in the last few months because I know she's not a good character, so I don't want to talk to her."

"Did you go to the victim's room this morning?"

"No, I've been at home all day."

"The police knocked on the door and saw that you were working, and you were in good spirits, why? Didn't you work the night shift last night? Why didn't you sleep? ”

"Because I slept during the night shift, I didn't feel very sleepy when I came back, and after lunch, I started cleaning up the house, and while I was doing my laundry, I heard the police knock on the door."

"Then did you hear the sound of a quarrel or a fight in the victim's house today?"

"I didn't hear that."

"Your place of residence is not far from the victim, and you haven't heard any sounds?"

"If I say sound, I seem to remember someone hurrying down the stairs near noon."

"Going down the stairs?"

"Yes, in a hurry."

"What about the sound of going upstairs? Do you hear the sound of going upstairs? ”

"No, I only heard the sound of going downstairs, and the footsteps were not very heavy, so I can be sure that it was the sound of going downstairs."

Hearing this, Xu Tian and Lao Chen looked at each other, this case seemed to find something interesting, then the next thing was the questioning of the first suspect.
