The policeman glanced at the woman's pregnant belly, his face softened a little, and he said with a cold face: "We don't know what the specific things are, this is an order from the bureau, and we are only responsible for carrying it out." ”

Sun Jianguo frowned and looked around, coughed lightly, walked forward quickly and asked, "Are you comrades from the Jinghai District Police Station?" I am Sun Jianguo of the Criminal Investigation Team of the Municipal Bureau, and I am responsible for coming here to investigate the scene. ”

The policeman turned his head, saluted and said, "Captain Sun, I am the director of the Jinghai District Police Station, Li Zheng." Ten minutes ago, the police station in our jurisdiction received a notice from the city bureau, and immediately sent the police to control the two people in the house, this man is the head of the house, named Guo Chao, and the woman is his wife Tian Ge, because she is pregnant, it is inconvenient for us to take the next step. ”

Sun Jianguo saluted in return and said quickly: "Okay, you wait here, the city bureau will send additional people to take over here, we are going to inspect the house now, and these two people will be handed over to you for the time being." ”

After explaining the matter, Sun Jianguo took the three of us to the bathroom first. Judging from the situation of the corpse, the bathroom is undoubtedly the best scene for the corpse, the blood and filth produced can be washed away by hot water, and the space of the bathroom is small, it will not produce a large area of pollution, and it is easy to clean.

When I found the bathroom, I took a general glance and it was clean, with white tiles on the walls and floors, and the smell of lavender in the air. In addition to a sprinkler, there is also a sink and a bath, and the small space is crammed to the brim. Zhang Bin walked around the bathroom, and finally squatted down at the base of the wall, took out a brush from his bag and gently brushed it in the tile joint, and put a plastic skin against the wall below.

Hearing Guo Chao's laughter and the woman's noise coming from outside the house, I asked Liu Yefang suspiciously: "Senior sister, I don't think the situation of the owner of the house, Guo Chao, is not like a murderer, he has a wife, and he is pregnant, he can't do anything to sexually assault a girl in front of his wife no matter what." ”

Liu Yefang shook his head lightly and said hesitantly: "It's hard to say, I'm not sure about this, the specific facts still depend on Zhang Bin's test results." I remember that Mr. Lu Xun said that 'I have never been afraid to speculate on Chinese with the worst malice', in the years of studying criminal psychology, I have seen many former gentlemen, behind the cunning fox-like villain, so look at people or don't just look at the surface. ”

Seeing that Sun Jianguo and Liu Yefang both looked solemn, I had no choice but to say, "Okay, then let's see the test results." ”

"Binzi, how long will it take for you to come out to solve the fruit?"

After waiting for a while, Sun Jianguo suddenly asked, Zhang Bin thought for a few seconds and returned: "The fastest is about twenty minutes, mainly to see if the components of the blood can be detected, if not, the suspicion can be basically ruled out." ”

"Then you check first, I'll take the two of them to ask the couple first. Keep in mind that the place of dismemberment may not only be the bathroom, but you will also have a look in other rooms later. ”

After explaining Zhang Bin's task, Sun Jianguo shouted Liu Yefang and me and commanded: "Xiao Liu, you will take the woman into the bedroom later, make some simple inquiries, remember to knock on the side as much as possible, don't go straight, to prevent irritating her." Xiao Xu followed me to ask Guo Chao and see if he could ask something in front of someone in the bureau. ”

Walking to the outhouse, Liu Yefang didn't know what to say in the ear of the pregnant woman, and the woman who was irritable and abnormal a second ago immediately became very docile and honestly followed her to the bedroom. Seeing this scene, Sun Jianguo sat on the sofa a little more easily, looked at the restless Guo Chao and said, "Young man, don't be nervous, because this case is very bad, and we have to be cautious." But rest assured, we will never wronged any good person. ”

"We received the police this morning, someone was splashed with sodium hydroxide solution in People's Square, and his face was seriously burned, according to our investigation, you had bought sodium hydroxide chemicals at Chen Wanda Chemical Store on June 7, so I hope you can tell me where the chemical raw materials are finally going, and where you have been in contact with in the past half a month."

When I first heard Sun Jianguo's words, my mind was a little foggy, but I immediately reacted, he was knocking on the side, and sure enough, Jiang was still old and spicy.

Guo Chao repeated the sentence suspiciously: "Sodium hydroxide? I bought it and put it in the laboratory department of the hospital, and I didn't take it home, so I don't know where it was taken after that. ”

Sun Jianguo nodded thoughtfully, "That's the case, then where have you been all these days?" ”

"Because my wife is pregnant, I have been on the same line for the past two months, going to work in the hospital during the day, passing by the vegetable market to buy some vegetables after work and coming back to accompany my wife, and I haven't been to other places. Otherwise, I will be scolded when I go home, my wife is pregnant and has a very bad temper, so I don't dare to make her angry recently. ”

Speaking of this, Guo Chao's face showed a little guilt and pity, and at the same time he turned his gaze in the direction of the bedroom.

"Okay, the city bureau will send someone to let you go to the bureau to make a record, and please cooperate with our work."

After a brief questioning, I felt bored and ran to Zhang Bin, and saw him lying on the ground with a strong flashlight and didn't know what he was looking at.

I walked behind him, and when I saw it, I couldn't help but ask, "Brother Bin, what are you doing here?" ”

Zhang Bin said without looking back: "I look at the situation in the floor drain, if this is the scene of the corpse, even if the bathroom is clean, there will be a little trace of blood left in the floor drain." Because of the fear that the sewer will be blocked, the pipe under the floor drain is not straight down, but has a corner facing up and then down, and the bottom of the 'V' is part of the pipe, where there is a dead end, which is difficult to be washed clean. ”

"Awesome, Brother Bin, you can think of this, how about it, is there an abnormality?"

Zhang Bin carefully pulled out a colander-shaped thing from the floor drain, which contained a black thing the size of a soybean grain, put it at the bottom of the test tube, and poured an unknown solution into the test tube for a slight shock, carefully observed for a few minutes, and finally shook his head in disappointment and said: "There is no trace of blood found for the time being, which basically excludes the possibility that this is the scene of the corpse." ”

I proposed, "Why don't you go to the kitchen?" There may be residual blood on the knives. ”

"Okay, it's okay to stay here."

Zhang Bin simply packed up his things, and when he walked out of the house, he saw that Wu Shuangshuang happened to bring people over, Guo Chao followed them very cooperatively, and did not forget to go to the bedroom to say hello to his wife before leaving.

Zhang Bin looked back at me and asked suspiciously, "Xu Jifeng, do you think such a person may be a murderer?" ”

I looked at Guo Chao's back, touched my nose and said, "Anyway, I don't think it looks like it, but since there is a suspicion, I still go through the process to prevent fish from slipping through the net." ”

"Also, the heart is in the belly, it's better to be cautious."

In the kitchen, Zhang Bin and I found a total of four knives, one was a knife for cutting vegetables, one was a thick knife for chopping bones, and a fruit knife and a carving knife.

Later, Zhang Bin and I conducted a detailed inspection of every room in the house, including the refrigerator and the bottom of the bed, and finally nothing abnormal appeared.

I should have been disappointed when I saw such a result, and suddenly felt a little lucky, if I really found that there was blood remaining, so as to determine that Guo Chao was the murderer, I am afraid that my outlook on life will be subverted.

Zhang Bin walked to the living room and made a brief report to Sun Jianguo, who was sitting on the sofa waiting for the results: "Deputy captain, I have searched the house, and no traces of blood have been found, which basically excludes the occurrence of murder and dismemberment in the house." ”

"It's expected, let's put the matter here aside for a while, let's go to Jin Wei's house at Songhai University to have a look." Sun Jianguo thought for a while and said with a little disappointment.

Knocking lightly on the bedroom door, I pushed the door in and gestured to my senior sister, and when I saw her nodding, I retreated.

Without waiting for a few seconds, Liu Yefang came out of the bedroom, and Sun Jianguo asked casually: "Did you find anything?" ”

Liu Yefang shook her head helplessly, and spread her hands: "No, according to Tian Ge, Guo Chao has either been at home or working in the hospital in the past two months, and has never been anywhere else." And the person is very honest, the interpersonal relationship between the hospital and the community is handled very well, and he often comes to visit the house. ”

Sun Jianguo rubbed his temples, squinted his eyes and said hoarsely: "Then lower the suspicion here for the time being, and wait for new clues to appear before making a judgment." There is also a request for the bureau to go to the hospital to investigate the final whereabouts of the batch of sodium hydroxide to see if it has been used as a cleaning container, and this clue can only be put down after it has been identified. ”

After finishing the inspection at Guo Chao's house, we drove to Songhai University, and after finding Jin Wei's residence, we stood at the door and looked inside, and the four of them looked at each other, almost ruling out his suspicion.

All kinds of certificates are hung all over the wall, some can't be hung, they are placed on the table below, the furniture in the house is in the style of the seventies, the varnish on the surface of many wooden furniture is almost peeling off, the most things in the room are all kinds of books, and the bulky TV in the living room is the only large electrical appliance in the room.

When we entered the house, we saw that the police in the jurisdiction were talking to a white-haired old man, and when we walked in, the police first introduced the identity of the old man.

"You are from the criminal investigation team of the Municipal Bureau, this is Professor Jin Weijia, a chemistry expert with a high reputation both nationally and internationally, and he is sixty-seven years old this year."

After listening to the introduction, several of us were embarrassed to mention the matter of the examination again, the old man in front of him can be ruled out from the physical strength alone that he is the murderer of the 7.14 murder and corpse mutilation case, and the people who committed the murder and mutilation of the corpse are at least young adults, from this point can rule out the suspicion of the old man.
