In fact, fortunately, it was also Fang Xiaoya's luck, the corpse she saw at the scene for the first time was not particularly strange, she died of gas poisoning, or carbon monoxide poisoning, and the death was not terrifying, so this girl did not have any special reaction.

"Team Leader Chen, can I meet the informant."

"Of course, it's the child's teacher and neighbor, just outside the gate, and I just asked Xiao Juan'er to accompany me."

Coming out of the house, Fang Xiaoya was not in a hurry to go out to see the informant, she turned her head and looked back and forth at the courtyard, when she came in just now, this place gave her an inexplicable sense of familiarity.

After looking at it for a while, she reacted, the layout of this yard is almost exactly the same as the yard where she went to arrest Tang Zhifei last night, except that the open space in the yard is slightly larger than the one last night, and there are two families living in this yard, and one of the informants is a neighbor.

Turning around again, Fang Xiaoya turned around and walked out.

The gate was already tightly surrounded by nearby neighbors, and if it weren't for the people from the police station who were blocking it, they might have been eager to rush in.

"Xiao Juan"

"Xiaoya, why did you come out?"

"I'm here to see the informant, who is the neighbor of the deceased?"

"It's Aunt Cheng, this is the child's homeroom teacher, Xue Ling." Xiao Juan, a member of the fourth group, turned around and introduced.

"Hello Teacher Xue, hello Aunt Cheng, is it convenient to come to your house? I'd like to talk to you both, there are so many people here that it's inconvenient to talk."

"Absolutely." Aunt Cheng's legs are not very good, and she wants to go home and sit after standing for a long time.

The house is not big, but it can be seen that Aunt Cheng is very diligent, and the house is cleaned up.

Fang Xiaoya noticed that there seemed to be only one trace of one person's life in this room, which made her a little curious.

"Aunt Cheng, this house ...... You're the only one living there?"

"Yes, the old man is long gone, and now, I'm alone."

Xu is used to it, and when it comes to this, Aunt Cheng's face does not have the slightest strange expression.

"Aunt Cheng, what's the situation at the house next door, can you introduce it to me?"

"Of course you can, the two men next door are called Guo Shuangqing, and the woman is called Liu Qiao, who was introduced by the street office and rented to me in five or three years."

"Aunt Cheng, wait, do you mean that this yard belongs to your family?"

"Yes, this yard is our family's, and when the street office saw that I was only one person and had two houses, they discussed with me if I could rent out one, and I could also collect a rent to supplement my family, and I didn't have much money, just two yuan a month."

"Where do they work?"

"Shuangqing is doing procurement in the bearing factory, old business trips, always going out for a week and ten days a month, and the place is not far away, just in Jin City, Liu Qiao has no job, and he helps out in the matchbox factory in the street, or I introduced it.

The child of the two of them is named Guo Jianguo, and he is in the first grade of Hongxing No. 1 Elementary School, no, is Teacher Xue also there, this morning Teacher Xue found out when he saw that Jianguo's child didn't go to school."

"Aunt Cheng, didn't you notice anything abnormal in their house this morning?"

"I'm old, I get up early in the morning, I go to the vegetable market every morning after getting up, and then I come back to chat with people at the entrance of the alley, and it's the same this morning, I still saw Teacher Xue, so I came back with me, and when I came back, I found that it was all like that."

mentioned Liu Qiao and Guo Jianguo, a sad look appeared on Aunt Cheng's face, and even her eyes turned red, which didn't look like a fake.

"Guo Shuangqing is not at home, is he on a business trip again?"

"Yes, he only left yesterday afternoon, and he specially greeted me when he left, hey, who would have thought that this kind of thing could happen at home when he just left."

"Did you open that window of the Guo family this morning, or did it open itself?"

"Comrade, I pushed it open in the morning, and when I went in, the smell of burning coal in the house was very strong, so I pushed the window open first." At this time, Xue on the side

Teacher Ling Xue said timidly.

"Teacher Xue, when you back the window in the morning, it was inserted from the inside, or was it just closed?"

"Ugh...... It's just closed, not plugged in."

"Oh, comrade, how can the window be plugged in?" Aunt Cheng took the words again.

"It's cold, the stove is all in the house, and although there is a chimney, there are many accidents every year because of this.

So normally, when I sleep at night, I leave a crack in the window, you see my house." Aunt Cheng said and raised her hand to the side of her window for Fang Xiaoya to see.

Indeed, the window of her house is left with a narrow slit.

Not to mention here, Fang Xiaoya remembered that the windows at home were also like this, and Li Heng also specially nailed a small piece of wood to the window frame, just so that the window would not be blown by the wind and shut it himself.

"Who knows what's going on with this Liu Qiao, I have the impression that the windows of their houses are usually opened."

Aunt Cheng's whispered words made Fang Xiaoya pay attention, she marked her notebook, and prepared to look at the window from the outside later.

After chatting with the two of them for a while, seeing that she couldn't ask any more useful information, Fang Xiaoya got up and walked out of Aunt Cheng's house, and looked around the courtyard again.

"Comrade Fang Xiaoya......"

"Team Leader Chen, have you had any results from the forensic examination?"

"The preliminary judgment is that it was a death from carbon monoxide poisoning, and the specific time of death is between 2 and 4 o'clock in the morning. Did you ask what you asked?"

"No" Fang Xiaoya shook her head and said, "I didn't ask what the result was, the male owner went to Jin City on a business trip yesterday afternoon, and there was an accident at home in the evening, tsk...... What does Team Leader Chen think?" ap.

"I'm more inclined to be an accident, we have already inspected the house just now, and we didn't find any traces of a third person, it's cold, and this kind of accident has happened a lot."

"Team Leader Chen, do you also have a stove at home at night?"

"That's for sure, there are still cracks in the windows, so I'm afraid of accidents."

"Yes, our family too, Li Heng also nailed a piece of wood to the window frame, I asked him what he was nailing it for, and he jokingly said that he was afraid that if the wind blew the window closed at night, we were both poisoned."

"Hey, Director Li is really good at finding a way, this is a really good way, I'll nail the wood to the window frame when I go back at night."

"I don't think it was windy last night." After staying outside for so long last night, at least there was no wind in the first half of the night, Fang Xiaoya was very sure of this.

Judging from the time of death, it means that the windows of the Guo family are likely to be closed when the two of them are resting.

"That Aunt Cheng said that the windows of the Guo family usually leave cracks, why didn't you leave them last night? Didn't Liu Qiao check the windows before going to bed at night?"
