Ancheng real estate

In the heat of July, the streets smell of being baked by the sun. The town, which was supposed to have a quiet lunch break, was awakened by the siren, and the warning line surrounded the garden community for three floors. Aisin and her colleague Dewey drilled through the cordon and entered the residential building. Huayuan Community is a newly developed community. At this time, some buildings were under construction, and the deceased lived in a newly-built building.

"Sister Xin, what's the smell of this staircase?" Dewey covered his nose and complained.

"Formaldehyde smell, all new houses have this smell, but I also smell a little perfume." Ai Xin said he didn't pay attention to Dewey. He quickly went upstairs and entered the dead man's house. Forensic Liu An and another criminal police officer Qin Song have arrived at the scene.

"The dead lie flat on the bed, his face is very peaceful, and there is no sign of fighting indoors. This doesn't look like murder. "

"Don't jump to conclusions yet," said Ai Xin, observing the whole house.

"Liu An, when was the time of death of the deceased?"

"Judging from the situation of the body, the time of death should be between two and three in the morning today. I want to take the body back to the station for further examination. " Liu An and his assistant took the body back to the police station. Ai Xin is still observing the house carefully.

"Dewey, do you think this house is strange?"

"Nothing strange, just empty."

"Yes, it's strange, deserted here. The smell of formaldehyde in this room is still there, and there are no basic furniture and appliances. The weather is so hot that the air conditioner has not been installed. Why did the deceased come to live here? " Aisin and Dewey observed the house several times, but found two floor fans in the dead man's room and two wardrobes in another room. They found nothing else. Because of the hot weather, this floor fan should be used to cool down.

"Qin Song, who reported the case?

"It's the staff who came to install the wardrobe today." Qin Song replied.

"Well, let's go back to the station, Qin Song. You take the person who reported the case to the police station to make a record, and I will go to him to learn more about the situation. " No sooner had Aisin and his party returned to the station than they saw that the Dragon Bureau was already waiting. A murder happened in a small town, which caused people's panic. Emphasis has been placed on focusing on.

"The little moxa, this case is very important. Be sure to find out and give everyone an explanation. "

"Dragon Bureau, I must get to the bottom of this case." Off the dragon director, Ai Xin immediately let Dewey make a record of the staff who installed cabinets today, and let Qin Song investigate the identity and social relations of the deceased. Qin Song will be back soon. "Xin elder sister, investigate clearly. The deceased was named Luo Liming, a chemistry teacher in Ancheng No.1 Middle School, and his wife was a physics teacher in Ancheng No.1 Middle School, but her wife had already resigned. "

"Ok, I see, let her wife come and recognize the body." Dewey came back as soon as Qin Songgang left. "Have you finished recording?" Aisin asked, "What's so special?"

"Nothing special. According to him, he installed a cupboard this morning. Mr. Li placed an order online and our staff was responsible for the installation. "

"Ok, I'll go to this person to know about the situation. Go to Liu An and see if there is any progress? " Ai Xin thinks this case is always a little strange, and he can't say why. It seems that from the moment he walked into the Li family, he felt this way, perhaps because of the professional sensitivity of criminal investigators. Lv Yuan, an installer, was brought by the police, but this Lv Yuan walked unsteadily and his hands were still shaking, although it was not obvious.

"Mr. Lu, how did you get into the house of the dead? When you went to install the cupboard, Li was already dead. If there was no one, shouldn't you knock on the door and leave? "

"I, I, I am, I don't think anyone, but in addition to the basic salary, we have a certain commission for people in this position. I wanted to earn more money, so I called to see when Mr. Li would arrive. I didn't expect to hear the phone ring in the room when I was on the phone, but no one answered it several times. Mr. Li's house is a new house, which has just been renovated. By rights, he should not be there. Lu Yuan stammered a little.

"Do you know the deceased?" Ai Xin asked.

"I don't know him. His wife is in charge of our installation team, so I know him. " After asking Lu Yuan, send him home. Qin Song also came with the wife of the deceased.

"Sister Xin, this is Tong Fang, the wife of the deceased Li," said.

"Hello, Ms. Tong." Out of sympathy for the family of the deceased, Ai Xin shook her hand, only to find that her skin was cold and her expression was dull. Liu An told Ai Xin that the deceased died of suffocation, but not because of mechanical suffocation. There was no trace of mechanical violence on the body, but the ingredients of sleeping pills were detected in the stomach of the deceased.

"Dewey, you go and check whether the deceased has insomnia and whether there is a history of purchasing sleeping pills." Du Weigang is going to have a look. Ai Xin thought for a moment and whispered to him, "See if his wife has bought sleeping pills." Dewey looked at Ai Xin, then at Tong Fang in the morgue and nodded his head. I think Li's death is very strange, especially Tong Fang's performance is very strange, and he didn't show too much sadness.

"Qin Song, let's go to the scene again." Aisin and Qin Song came to the scene. As soon as I got downstairs, I saw a woman coming down with a headscarf and sunglasses. They were frightened when they saw someone. Ai Xin gave her a look. "Xin elder sister, this person is really strange. He is wrapped so tightly on such a hot day. " Ai Xin looked back at the woman in a panic and felt very strange. When I came to the Li family, there was nothing in the dead man's room except a bed and two floor fans. Aisin stood at the door of the room, looking at the position of two electric fans. Suddenly, I made an important discovery. Ai Xin hurriedly called Qin Song, but I didn't expect Qin Song to come first. "Sister Xin, I found something dirty in the closet."

"Quick, call Liu An, let him come and get a pressure gauge" leng for a while, hurriedly dialed the telephone of Liu An. As soon as Liu Angang entered the door, he told him that he had found the real reason for Li's suffocation. Aisin asked Liu An to put the manometer where Lori Ming was lying, and turned on two electric fans. Soon, he found that the value of the manometer dropped rapidly.

Liu An patted his forehead, so that's it. This is the principle of fluid mechanics. The two fans were placed on both sides of the bed end of the deceased, so that the directions of the two winds were parallel. The victim was between these two parallel winds. Because of the high air velocity on both sides of the body of the deceased, the air pressure will decrease, and the pressure at the position of the deceased is relatively high, which will make the air in the middle spread to both sides and the air pressure will decrease rapidly. In addition to breathing through the nose and mouth, pores will suddenly breathe.

"Could it be that the deceased accidentally put these two electric fans in this position?" Qin Song asked.

"No, this is murder. It is the dirt in the closet that you just mentioned that makes me more convinced that there was a second person on the scene the night Li died, and this second person was hiding in the closet. "

"Qin Song, go and see who gave the wardrobe that day."

"Ok, I'll check it right away." Qin Songling was ordered to go quickly, and the case finally had some results.

Aisin told Liu An to go back to the team. She had to check another thing. When I passed the woman, I felt very strange, not because of her strange dress, but because she smelled a familiar smell, just like the smell she smelled in the Li family that day. Ai Xin went to the residential guard to investigate and monitor, and found the woman's multiple access records. However, it is not easy to see the face clearly because it is wrapped tightly every time. Uncle Security looked at the surveillance screen and said, "Comrade, are you looking for this woman?" I know who she is. "Ai a stare blankly for a moment in the heart, then asked with delight:

"Uncle, how do you know who this woman is?"

"That is, no one in Quanan knows, Su Yi, a beautiful woman."

"I met her a few months ago. At that time, she came with a man. She should come and see the house. I know that man, too. My little daughter is studying in Ancheng No.1 Middle School. This person is a teacher. "

Show Li's photo to the security guard, who recognized him. Driving back to the station, thinking about the relationship between Su Yiwen and the deceased Li and the way the suspect killed Li. This is obviously a person with a certain level of knowledge, but think about the dirt in the closet, which is probably left by the suspect accidentally. If the murderer is Su Yiwen, she can go straight to Li's house. Why did she stay in the closet?

Back to the station, Ai Xin said to Qin Song, "Check the information and address of Su Yi. It seems that we are going to visit her. " In the face of the sudden visit of the police, Su Yi seemed a little panicked. Ask her about Li's relationship with. Su Yiwen said that she and Li were just friends. They used to be classmates in junior high school, but they dropped out before they finished junior high school.

"So where were you on the night of July 3rd?" Faced with this problem, Su Yi seems a little flustered.

"On the evening of July 3, I had appendicitis and was hospitalized." Ai Xin felt lost in their hearts. If she is telling the truth, she may not have time to commit crimes. Ai Xin and they were about to leave when Su Yiwen's husband came back. This man was none other than Lu Yuan who installed cabinets for the Li family that day. But this time, Lu Yuan walked steadily and didn't stutter with them. On the way back, Ai Xin remained silent on the co-pilot. "Sister Xin, how can this Lv Yuan and Su Yi be a couple?"

"What's the matter? Do you have an opinion? "

"I dare not have opinions, but Su Yi is so beautiful ..."

"Go to the hospital to see if what Su Yi said is true." Qin Song bitterly shut up. After coming out of the hospital, Qin Song said a little dejectedly, "It seems that what Su Yiwen said is true."

"No, although she didn't commit the crime, her relationship with Li is not that simple, but it has little to do with the case."

"Qin Song, do you think it will be a thief shouting to catch a thief?"

"Sister Xin, do you doubt Lu Yuan?" Although Lu Yuanming doesn't know him well, Li won't sleep when Lu Yuanming is still at home, but in case Lu Yuanming hides in the closet on the afternoon of the night of the murder, and then comes out to kill people while Li is asleep at night.

"I think Lu Yuan is not such a thoughtful person. Besides, what is his motive for killing people? "

"Anyone who wears a cuckold will be unhappy. Ai Xin said, "It seems that Lu Yuan is coming again. "

Lv Yuan said that the afternoon's work was originally her own, but her wife was not feeling well and wanted to ask for leave with the child. I didn't expect Tong to ask for leave that day. I didn't see her, so I let someone else send it. Aisin asked Lu Yuan again, and Lu Yuan said there was nothing suspicious.

"Let's go to the crime scene again and see if there are any missing clues." The party came to Li's home again.

Ai Xin looked at the wardrobe carefully. Except the plastic film of the door was damaged, the other parts of the wardrobe were still intact. Moreover, according to the staff who delivered the wardrobe that day, Li opened the door for them and went out with the staff. He didn't check. This kind of damage should be left by the murderer, but how did the murderer know that Li would come back and wait here after going out? Ding's cell phone rang, and it was calling.

"Elder sister, have a clue. Li has no history of insomnia and buying sleeping pills, but he has an unexpected gain. Yan Fang once bought sleeping pills. " Ai Xin was so excited that he suddenly thought of something.

"Quick, go back to the station and let Tong Fang come." Seeing Tong Fang again, she was even more haggard. She began to stagger and her hands could not help shaking. As soon as Tong Fang sat down, she took the lead and said, "I killed Li." Ai Xin didn't expect her to admit it so soon, and other policemen were stunned.

"I gave up so much for him, but he betrayed me. Do you think he should die? "

Tong Fang stammered when she said these words, and her expression on her face was still dull, but her mood was very unstable. Tong Fang knew that Li and Su Yi were not proper relationship, and on the day of the incident, he heard Li call Su Yi to let her go to the new house to put on the clothes she bought, so he took the opportunity to send the wardrobe to the Li family for fear that Li would find it hidden in the closet. I didn't expect him to rush out as soon as he opened the door, so she must have picked up Su Yi.

After he went out, Tong Fang came out quietly and put sleeping pills in drinking water. According to Tong Fang, she originally wanted to kill the couple, but Su Yi suddenly felt sick and went home.

"Then how did you get out? Why didn't I see you on the surveillance video? "

"You should have seen it." Tong Fang grinned. Camouflage is not difficult, and no one will pay attention to cleaning up the garbage. After they went out, Ai Xin was surprised by Tongfang's behavior. I didn't expect her to admit it so soon. Standing outside the interrogation room, Liu An kept a close eye on Tong Fang's every move in the interrogation room. Tongfang's behavior seems to be poisoned If she was poisoned, who poisoned her? Does she know that she has been poisoned?

"Ai Xin, I need you to take a hair from the same side." Judging from Tong Fang's behavior, she seems to be poisoned by mercury. Ai Xin got Tong Fang's hair and found that the mercury content in her body was many times that of normal people. Ai Xin thought of Lu Yuan's previous performance, which seemed to be a symptom of mercury poisoning. Who poisoned them? Ai Xin felt that one case after another was pending. Ai Xin sat in front of the whiteboard and analyzed the chart of this case. Li and Su Yi are lovers, Li and Lu Yuan are husband and wife, Su Yi and Lu Yuan are husband and wife, and Lu Yuan killed Li, so who is the beneficiary of Lu Yuan and Lu Yuan's accident? Ai Xin suddenly understood.

Tong Fang and Dewey went to Su Yiwen's home again. Ai Xin told her about Tongfang's poisoning. When Ai Xin saw Su Yi's hand clutching her skirt tightly, she was particularly nervous. Under the coercion of Ai Xin and them, Su Yi's psychological defense line was finally breached.

"I tell you everything, but can you promise me one thing? Please don't tell him about Lu Yuan's poisoning. I haven't poisoned Li since he died. I, I really want to live with him. " Su Yi said, tears streaming down her face.

All this was planned by Li. He had a problem with Tongfang, but that was his own business. If he is divorced, let alone Tong Fang's wishes. In the division of divorce property, he will definitely suffer, so he wants to kill her, so he thought of such a poisoning method to let her die slowly, unnoticed. He knows the living habits of Tongfang. He uses an air humidifier during his nap, so he puts mercury in it and never goes home at noon. Lu Yuan didn't have such a habit, so Li gave Su Yi mercuric chloride so that she could put it in pies and so on.

Ai Xin and they returned to the station, and Liu An explained the situation. "Alas, Liu An sighed, mercury vapor is colorless and tasteless. Mercury vapor will not cause respiratory diseases unless inhaled in large quantities. This metal will be absorbed by the lungs, enter the blood circulation system, and then be sent to all parts of the body through the blood circulation system, but the nervous system is easily affected. Once mercury enters the brain, it will cause a series of symptoms such as listlessness and unstable walking. The couple had so much knowledge that they didn't expect to use it to murder each other. "

The case has been closed, but Ai Xin's heart is still like a big stone. (Author: Silent Man)
