"Uh......" Fang Xiaoya's question made Team Leader Chen stunned for a moment, he turned his head to look at the window of Guo's house that was currently open, and looked at it for a while before turning around and saying: "I don't know the situation of their family, but our family, whether it's me, or my lover, even if it's my son, we will intentionally or unintentionally check if the window is open before going to bed." ”

Saying that, the two of them had already walked to the window of Guo's house at this time.

Team Leader Chen stretched out his hand and pushed the window, probably because of the long time, the window frame may be a little out of shape, if you don't lift the window up a little, it can't be closed at all, it can only be touched gently.

"Team Leader Chen, wait a minute, I'll ask that Teacher Xue again." Seeing this, Fang Xiaoya turned around and walked towards Aunt Cheng's house.

"Teacher Xue, when you pushed the window after entering the house, was the window closed, or did it just touch it gently?"

"Hmm...... Confined. Xue Ling frowned and thought for a while and said with great certainty: "It must be confined, because I didn't push it away the first time, and I thought it was plugged in, so I took a special look at it, and when I saw that it wasn't plugged in, I pushed it hard again before I pushed it away." ”

That is, this window must have been closed artificially.

But what happened to make them close their windows? Countless question marks appeared in Fang Xiaoya's head at this moment.

It seems that only when Guo Shuangqing comes back can there be an answer to this question.

"Fang Xiaoya, what's wrong?" Seeing that she looked thoughtful after she came out of Aunt Cheng's house, Team Leader Chen asked curiously.

"Teacher Xue said that when she pushed the window, the window was closed, Team Leader Chen, under what circumstances do you think this will happen?"

"Closed? They whispered at home and didn't want outsiders to hear it, and then forgot to turn it on? ”

Speaking of this, Team Leader Chen turned his head to look at Aunt Cheng's house, this courtyard is the only outsider to the Guo family is Aunt Cheng.

"Yes, let's not guess, just wait for Guo Shuangqing to come back and ask, Team Leader Chen, you will send someone to inform them of the unit, right?"

"Well, the comrades from the police station have already gone to ask them to take a telegram to Jinshi in the factory, and let Guo Shuangqing come back as soon as possible."

said so, but in fact, Fang Xiaoya, Chen Gui, the leader of the fourth team of the Criminal Investigation Department, including his team members, and the forensic doctor sent by the Municipal Bureau, all felt that this was an accident, after all, this kind of accident did not happen too much after the weather was cold.

Some were lucky and were rescued in time, and some were like Liu Qiao and her children, and they were already cold when they found out.

Every winter, the staff of the neighborhood committee will go door-to-door to notify that they must pay attention to ventilation when they sleep at night, and they must clean the chimney in time.

Not to mention now, even decades later, this kind of thing will happen a lot, especially in rural areas, where the stove is mainly used for heating in winter.

……

That night, Fang Xiaoya, who had eaten and drunk enough, was satisfied with her man's arms and talked about this case that was not a case.

After listening to her, Li Heng sighed and said: "Alas~ This kind of accident is indeed difficult to avoid, I have to check the stove and window before going to bed every night, and then check, I am afraid of any accidents."

However, it is not very likely that our family will have an accident, our stove is outside, and the house is so big, I really want carbon monoxide poisoning, and I have to burn it for a while, and the chimney is also blocked, and the windows are also closed. ”

As soon as his words fell, Fang Xiaoya, who was nesting in his arms like a kitten, seemed to be startled, and sat up suddenly.

"What did you say?"

As soon as she sat up, the quilt was lifted, and as soon as her delicate skin touched the cold air outside the quilt, a layer of goosebumps instantly appeared on her arms.

"Oh, my daughter-in-law, what are you doing, don't toss about catching a cold."

Seeing this, Li Heng hurriedly reached out and pulled the quilt to wrap her.

"Brother, what did you just say?" The little girl didn't seem to feel the cold, stared at her man with wide eyes and continued to ask.

"What do I say, don't catch a cold, lie down quickly."

Stretched out his hand and pulled it, but he didn't pull it, he could only stand up and wrap her with the quilt: "I said what's the matter with you, why are you so excited, you're not afraid of catching a cold." ”

His body has been modified to be not afraid of the cold, but the little girl can't.

"Oh, brother, you repeat what you just said."

Fang Xiaoya didn't care about being cold or cold at this moment, what her husband said just now was like a lightning bolt in her mind, making her feel as if she had caught something, but she couldn't figure it out, so she could only ask him to repeat what he just said.

"Huh? What did I just say? Li Heng was still a little puzzled at this time, he couldn't figure out what he was talking about, which made his daughter-in-law so excited.

Looking at the little girl who was successfully wrapped into a dumpling by him, he was relieved at this time, leaned back and asked a little puzzled.

"What kind of house is big and what is blocked?" Fang Xiaoya said with some eagerness.

"Oh, I mean because our house is relatively large, even if the windows are closed tightly, as long as the chimney is not completely blocked, we will stay in it, and we will die of carbon monoxide poisoning, and it will take a while."

"Big house...... Block ......" Fang Xiaoya sat there in a daze, repeating these words in her mouth.

"I said girl, what the hell is wrong with you."

"Don't interrupt, brother, you said that in a house as big as ours, how long will it take for the people who live in it to die of gas poisoning?"

"It's hard to say." Li Heng shook his head and said, "This needs to be experimented, but according to my estimates, it will take more than ten hours to completely die." ”

"So long?"

"No, I said girl, what do you mean, curse the two of us?"

"Oh, no, the ...... I just told you"

"Well, I know, didn't you say accidental gas poisoning?"

"But her house is a little smaller than ours, and it's also made like this inside and out."

"Girl, what the hell are you trying to say?" Li Heng had a feeling that the second monk was confused, what was this.

"I want to say, if our house takes ten hours to cause death, then the Guo family's house will also need about this time in the most extreme case?"

"Aang, it's possible."

"But the forensic doctor said that the time of death of the two girls was between two o'clock and four o'clock in the morning, according to Aunt Cheng, Liu Qiao had to paste the matchbox for a while at night before resting, and under normal circumstances, sleeping is after nine o'clock, this time is not right."
