After lunch, Shen Jiamu formally questioned Jiang Jiayu.

Jiang Jiayu is Xu Wenhui's left neighbor, the yard is twice as large, but the courtyard wall is also only about one meter high, and Xu Wenhui's yard only plays a "functional" role compared with it, it can be seen that Jiang Jiayu is a very interesting housewife, she planted a lot of flowers and plants in the yard, there is no drying rack installed under the canopy in the front yard, a small dining table is placed, and a rocking chair is placed.

There is a fake fireplace installed in the living room, purely decorative, the sofas in front of the fireplace are arranged as a reception area, and now Xu Qingsheng is sitting on one of the single sofas, Jiang Jiayu is sitting opposite her, although he is the master, but it can be seen that Jiang Jiayu is very cramped.

People are middle-aged, but Jiang Jiayu's figure is still slim, Xu is this world because of the servant, women save a lot of housework, this ordinary woman living in the township has a hand is not rough, the skin is delicate and white, at this time the rules cover the knees, and the back is straight.

Xu Qingsheng looked at a wall, and the photo hanging on that wall should be a family photo of the family.

Jiang Jiayu sat by the flower bed in the courtyard, a middle-aged man behind him put his hand on her shoulder, next to the middle-aged man was a young man, his eyebrows and eyes were a little like Jiang Jiayu, but the tall nose bridge followed the middle-aged man, and a young woman half-squatted beside Jiang Jiayu, but looked at the young man and smiled.

"Uncle Xie is not at home?" Shen Jiamu asked first.

"He went on a trip in April last year, saying that he was going to travel around the West, and he is expected to return in May this year." Jiang Jiayu added: "You can call his mobile phone, I also contacted him yesterday." ”

"Where's Xiao Xie? Didn't come back to visit you during the Spring Festival? ”

"Both of them are back, and they left on the third day of the new year...... He is busy with work, and the plan is to return to Kang in the third year of junior high school, and this Hengzhi family matter does not need to take much manpower to operate, so Mingxiu originally said that he would stay for a few more days, I didn't let her stay, Mingxiu's mother's house is in Shengkang, I heard that her eldest brother came back from abroad this year, and the two brothers and sisters are rare to see, so I am embarrassed to keep her in Jiuqu. ”

"Xiao Xie has a stable job now, and he has no plans to have children, why doesn't Aunt Jiang go out with Uncle Xie to play while he is free?" Shen Jiamu still seems to be gossiping.

But Jiang Jiayu was even more nervous, and Xu Qingsheng saw that her nose was as if she was twitching.

"Officer Shen, I hid something that day, I thought that the murderer who broke into Wenhui's house and committed the murder would definitely be filmed by the camera, I wouldn't be suspicious at all, there is something to do with the murder, there is no need to say it...... But now that the case has been handed over to Officer Shen for investigation, it must not be so simple, I ...... I've said it all, it's me who is greedy.

I heard my relatives say that there is a place in Changyan Town to be expropriated for commercial land, and the owner can get a large amount of economic compensation, I know that Wenhui has an old house in Changyan, so I asked for the detailed address, and told my relatives, he was sure that it was within the scope of the expropriation, I bullied Wenhui and didn't know about the expropriation, so I wanted to buy a house from her first to make a difference, Wen Ji didn't agree, on the 28th, I wanted to take the opportunity to chase / debt to force her to agree, just said a beginning, Xiaomei and Qiuzi came, I don't want to say more, I have been paying attention to the movements of Wenhui's house, but my son and daughter-in-law were there that day, and I didn't pay attention to when Xiaomei and them left for a while.

It wasn't until I saw Wenhui coming out of the courtyard that I called out to her, and said a few words about the house at the door of her courtyard, Wenhui boss was impatient, and said that he was going to Changyan immediately, and I didn't want to chase her to continue to talk, just like this, although I was greedy, I didn't dare to have the heart to kill, and I wanted money, Wenhui died, her inheritance was inherited by Sasha, and Sasha had to wait until she became an adult to dispose of real estate, if I killed Wenhui, I didn't have to buy her old house in Changyan at all. ”

Since Jiang Jiayu took the initiative to raise the case, Shen Jiamu simply asked: "After Wenhui left the house on January 28, did you see the lights in her home?" ”

"No, no, the lights haven't been turned on, so a few days later, Xiaomei came to Wenhui to ask me, and I insisted that Wenhui went to Changyan and was not at home at all."

"Where's the maid? Is there any activity for the helper in Wenhui's house? ”

"No, the curtains are drawn upstairs and downstairs in her house, and I can't see the situation in the room, so I don't see the maid moving in the yard...... But...... One night, it should be the second night of the Lunar New Year, the day before Wen Jie left, he drank with a few of his classmates from the previous college, and he didn't come back at half past ten, Mingxiu didn't go to bed early, saying that she heard some movement, like someone was throwing garbage outside, she heard the sound of the garbage bin lid when it was opened, Mingxiu was in the bedroom, looking out of the window, the backyards of several houses opposite were lit up, and I didn't see anyone or a helper, Mingxiu also said that the sound came from the right, and it was a little closer, and she wondered how no one in Wenhui's house had the garbage can lid opened. ”

Shen Jiamu took Xu Qingsheng to the second floor, the bedroom where Jiang Jiayu's son and daughter-in-law lived when they came home for the New Year.

This bedroom is the northernmost one, under the window is the backyard of the house, and then the block sidewalk, from this window you can see the neighbor's backyard on the north side of the sidewalk, but you can't see the backyard of the Wenhui family completely - even if you lean out, you can only see a small part of the backyard - the view is blocked by the Wenhui family's utility room, and the Wenhui family's garbage bin is installed on the right side of the utility room.

Shen Jiamu did not miss the garbage bin at the scene of the murder, but the local police station had already inspected the garbage bin, and the garbage bin was cleaned up.

When he returned to the mansion, the time was close to three o'clock, and Shen Jiamu only had time to explain to Xu Qingsheng a little about the problem of the garbage can.

The garbage bin in Jiuqu Town is generally installed in the backyard of each house, which is embedded in the courtyard wall, and the owner does not need to go around to throw garbage outside, but the public servant of the block can pass through the outside, open the lid of the box and directly collect the garbage and send it to the garbage station for processing, the public servant will start cleaning up at 3 o'clock in the morning, and when he arrives at the garbage bin of Wenhui's house, it is 3:40 in the morning, the time is fixed, and there will be no deviation.

Wenhui's body was only found on February 4, and there was no residual garbage in her house or in the garbage bins in her backyard, which seems to indicate that at least before February 1, Wenhui was not at home in Jiuqu Town, which is consistent with her activities in Changyan, but this world is a world where there are servants.

If Jiang Jiayu and his daughter-in-law were not lying, Wenhui's maids should have discarded the garbage on the evening of January 30, but why would an uninhabited house produce garbage? The maid does not need to eat three meals a day, and only the maid is at home, so it is reasonable that no garbage will be generated.

When Xu Qingsheng crossed into this world again, she knew that Jiang Jiayu's testimony was true, and Jiang Jiayu was not lying.

Shen Jiamu asked Xu Qingsheng to look at the camera of the street road: "Not only on the evening of January 30, but also from January 28th to February 1st at about 11 o'clock in the evening, the camera recorded the prompt sound of the opening of the lid of the garbage can, you see, the utility maid did take the garbage from Wenhui's garbage bin at 3:40 in the morning, this kind of utility maid is a special purpose for cleaning and transporting garbage, and the chip is connected with the user's delivery and collection bin, if the garbage bin cover is not opened within 24 hours, the utility maid will not take the initiative to open the lid to clean up the garbage." ”

"This shows that from the afternoon of January 28, when Wenhui left Jiuqu Town, to the night of February 1, the night of her death, her maid was operating, at least throwing garbage into the garbage bin." Xu Qingsheng speculated.

"That's right, Wenhui was at home on January 28, if she regularly asked the maid to sort out and transport the garbage to the backyard at night, it would not be surprising that the maid began to carry out the order on the evening of January 28, but after January 28, at least until February 1, Wenhui should be in Changyan, the house is empty, why does her maid still deliver garbage to the garbage bins? Unless Wenhui orders the maid to separate the garbage for a few days...... This is not logical. ”

"The murderer's intention is to make us believe that Wenhui was in Changyan after 6 pm on January 28, was killed in Changyan, and was transported to Jiuqu's home afterwards, and the murderer was in order to create proof of his alibi, but the crime was not perfect, and the murderer still left flaws." Xu Qingsheng said.

Shen Jiamu frowned, but he recognized Xu Qingsheng's reasoning: "Flaw one, experience corpse, Wenhui has traces of being tied up for a long time, and the time of being tied up is at least more than 48 hours, but a few hours before Wenhui died, many cameras in Changyan recorded her traces, and she was not restricted from moving; Flaw 2, Wenhui was tied to the living room sofa of Jiuqu House for a long time, and she left excrement before she died, which can be used as circumstantial evidence; Flaw three, Wenhui's maid received the instruction to remove the garbage, but this instruction could not be issued by Wenhui, because if Wenhui could still control the maid, she could completely instruct the maid to call for help. ”

"Did the maid do anything? This shouldn't be hard to see, right? Xu Qingsheng asked.

Shen Jiamu shook his head: "The constitution has a strong degree of protection for citizens' privacy, whether it is a maid assigned by the community or a maid purchased by a citizen, the maid program prohibits the implantation of the recording function, that is to say, the police have no way to understand the behavior of the owner and others through the analysis of the helper chip, although it is impossible for ordinary people to tamper with the instructions to trade other people's helpers, but theoretically speaking, people with professional knowledge can completely tamper with the instruction account, but if they illegally implant the murder order, it will immediately trigger the national ban system, It is impossible for anyone to command a servant to kill someone, but in addition to implanting programs such as murder and violence, tampering with the main account is also difficult to detect. ”

So now we can only infer that the maid accepted someone else's instructions, but it is impossible to decipher who tampered with the main account.

"Although the maid can't directly poison it, the murderer can completely order the maid to give the food he has poisoned to Wenhui for consumption." Shen Jiamu had apparently deduced the murder modus operandi.

Xu Qingsheng said: "Wenhui was restricted from moving, but of course she still has a fluke heart, as long as a person is alive, he can't eat or drink, I carefully inspected the first floor of Wenhui that day, the living room extends to the north and there is a passage of more than four meters, both sides of the passage are guest rooms, the guest room doors are locked, even if Wenhui can be opened with a key, but she also needs to push the doors and windows to be heard by the neighbors, only the door from the living room to the back house will be opened for a short time. "Because the maid has to go to the backyard to take out the trash.

"All doors and windows have the function of automatic closing, the maid is set to throw garbage at night, and the passage from the Wenhui living room to the backyard is four or five meters long, the maid pulls the door open and the door automatically closes only three seconds, the door is directly opposite a utility room, and the door of the utility room is also closed, even if someone happens to pass through the sidewalk outside the backyard of Wenhui at that time, it is impossible to hear the cry for help."

Shen Jiamu lowered his eyelids, and Qing Sheng couldn't see through the emotions in his eyes.
