Li Heng was busy with the first big exam he was about to face, and his wife also visited Guo's house again with several colleagues from the fourth group of the Criminal Investigation Department.
"After I went back, I also thought about it seriously. In such a big house, it is really suspicious to think that two people died of gas poisoning at the same time. Are these two women really sleeping like that?"
After coming in, Team Leader Chen looked around and then said.
"Team leader, there is a situation that can make them sleep like this."
"Xiaojuan'er, you want to say that someone drugged Liu Qiao and the child, right?"
"yes"
"Unfortunately, Guo Shuangqing did not agree to the autopsy. There is currently no evidence to prove that Liu Qiao and the child did not die in an accident. What we are talking about is just speculation, and there is not even a trace of clues." Chen Gui shook his head and continued to wander around the room.
stand up.
This house is like a main room upon entering. There are two rooms separated on both sides. One room is occupied by Liu Qiao and his wife, and the other room is occupied by their children.
Fang Xiaoya stood there as soon as she entered the door, her eyes looking back and forth at the stove in the middle of the room. After looking at it for a while, she raised her head and looked at the chimney.
A member of the fourth group saw her looking at the chimney and said, "How about we start the stove now, close the doors and windows, and see how long it takes for that kind of smoke to be produced in the house.
Suffocating carbon monoxide."
This is the stupidest method, but it is currently the only way to solve this doubt.
The coals in the stove were quickly ignited. Fang Xiaoya looked at the chimney that stretched out the window and was smoking, and suddenly thought of the issue about time that Li Heng told her last night.
"Look, Team Leader Chen, the chimney has been smoking, which means it is not blocked. So six or seven hours should not completely suffocate people inside."
"Could it be that the medical examiner's estimated time of death that day was wrong? He said it was from two to four o'clock, but in fact it should have been from four to six o'clock, or even an hour later."
Chen Gui also noticed the chimney, he thought about it and said hesitantly.
"It's very possible, but how could Forensic Doctor Wang make such a low-level mistake?"
"I don't know about that. Anyway, you saw it. Although there are some doubts, we really can't find any clues."
"Team leader, Xiaoya, come here."
Just as Fang Xiaoya was about to say something, Song Xiaojuan called out from outside the house.
"What's wrong, Xiaojuan?"
"Team leader, no one had touched this stool when we came here yesterday, right? Look at the footprints on it, are they very clear, as if they were new ones?"
Song Xiaojuan pointed to a wooden bench under the window and said.
"Stool? None of our people touched the stool yesterday. Aunt Cheng, does this stool belong to the Guo family?"
Chen Gui glanced at the big footprints on the stool, then raised his head and asked Aunt Cheng who was standing at his door and looking this way.
"It belongs to their family. After Guo Shuangqing helped me and their family install the chimney last week, it seems that it hasn't been moved in yet and has been left there forever."
After listening to Aunt Cheng's words, Chen Gui turned around and walked into the house. When he came out again, he had a stool in his hand. He looked up at the chimney mouth, then put the stool down, stepped on the stool and stood up.
After taking a look, he came down again, without saying anything, he just asked Fang Xiaoya and Song Xiaojuan to come into the house.
"What's wrong, Team Leader Chen? Did you find anything?" Fang Xiaoya asked eagerly as soon as she entered the room.
"It's hard to say whether it was discovered or not, but we have to dismantle the chimney and take it back for inspection. I just went up and found some marks in the chimney, it looks like something was stuffed there."
"Someone deliberately blocked the chimney?"
"It's very possible, but we have to ask Guo Shuangqing to see how he cleaned up the chimney before using it, and then let the trace inspection department see when the traces were formed. If it was really just formed, then Liu Qiao
With the death of the child, it is very likely to be an intentional homicide."
Look, isn't this a clue? Although it is still very vague, since we have found something suspicious, we must investigate it. If it is really a newly formed trace, even if Guo Shuangqing disagrees, they can ask for a forced autopsy.
And if he still doesn't agree by then, the suspicion will be greatly increased.
So, after Chen Gui and another team member sealed the stove, they began to dismantle the chimney, which made Aunt Cheng who had been sitting at the door of her house watching them stunned.
"Aunt Cheng, I want to ask you something."
"Hey, comrade, just ask."
Taking advantage of nothing else to do at the moment, Fang Xiaoya strolled over again to chat with Aunt Cheng.
"I just want to ask, where was the chimney placed before the Guo family installed the chimney?"
"Here, right there." Aunt Cheng raised her finger and pointed at the corner under the eaves of the house where the Guo family lived.
"Have you ever noticed how his chimney is cleaned when it is not in use?"
"How to clean it up? Aren't they all the same? Take some waste paper and wrap it up at both ends."
"Aren't you going to put something in there?"
"Who is going to put something in this thing? It just needs to be wrapped. Some people don't even wrap it. Anyway, you have to bang it when you use it. Comrade, what's going on? Why are you tearing down his chimney?"
"Oh, it's okay. We took it back for an experiment and gave it back to him. Auntie, aren't you afraid of living here alone at night?" Fang Xiaoya quickly changed the subject.
"There's nothing to be afraid of. I'm an old woman. I've never seen anything before. It's just a pity. It's hard to find a wife like Qiao'er. She's hard-working and capable. She can take care of the house inside and out.
Lisuosuo, you see that I am still helping me with work even when I am older. Jianguo's child is also smart and well-behaved. Oh, tell me, why can't good people live long? Why did this accident happen to her family?
It's also my wife's fault. If I had gone out late yesterday morning, I would have definitely noticed something was wrong. Maybe the mother and son could have been saved."
Aunt Cheng shed tears as she spoke. After living in the same courtyard for three years, she developed some feelings for her.
Aunt Cheng is in her fifties this year. If we look at the era names, she has gone through Guangxu, Xuantong, and the Republic of China to the present.
She had never seen any scene before, and it was nothing if two people died in the courtyard. She didn't care at all. Even though she was suddenly living here alone again, she felt a little lonely. She missed Liu Qiao and Guo Jianguo very much, and she blamed herself.
.
"Auntie, please don't think blindly, take care of yourself."
"Hey, don't worry, old lady, I'm in good health. Girl, how old are you this year?" Aunt Cheng looked at Fang Xiaoya, then suddenly her eyes lit up and she asked.
