After a while, the sound of a siren came from afar, it should be Li Jun and they brought someone here, and at this time, Sun Jianguo suddenly asked, "How did you get in touch with that person?" How do you get in touch when you trade? ”

Guo Chao laughed miserably: "Through the introduction of one of my old customers, that person specializes in reselling medical equipment, and now he has made a fortune and has immigrated to the United States at the end of June, and I don't know his current contact information now." ”

Sun Jianguo squinted and stared at him for a long time, until the police car stopped at the gate of the family courtyard and said slowly: "The detailed situation will wait until the police station, if you cooperate well, the crime you commit now can be dealt with lightly." ”

After Li Jun got out of the police car, he walked straight over, glanced at the two people who were handcuffed, and then caught a glimpse of a large pool of blood-colored things on the ground, pointed to the things and asked uncertainly: "Old Sun, what is this?" Entrails? ”

"The two of them said that it was placenta, and Xiao Xu and I have never seen this, so we have to wait for Ma Zhiyuan to come over for identification."

Sun Jianguo briefly talked about the situation just now, focusing on the theft of sodium hydroxide. Guo Chao didn't say a word during the whole process, and he looked like he pleaded guilty, but Tian Ge kept shouting that the police wanted to take them for the crime, and the noisy sound woke up the residents of the family home, and many residents stood at the windows and looked down.

Li Jun's temper was much better than mine, he glanced at Tian Ge expressionlessly, then looked at the lights lit up in the family courtyard, and said in a deep voice: "Take them all away, go back to the bureau and lock them up first, and then convict this woman and add a crime of obstructing official business." ”

"I'm pregnant, you can't do this to me, don't slander good people."

This time, before Li Jun could speak, Guo Chao stepped forward and grabbed Tian Ge with his handcuffed hands, and persuaded in a soft voice: "Tian'er, you don't say a few words, things have come to this point, let's honestly explain to the police comrades, I believe that the police will not wronged good people." ”

Seeing that there were more and more lights lit up in the family courtyard, Li Jun urged the people to be escorted into the police car, closed the door and said to the two of us: "Let's go back to the bureau first, there are many people outside." ”

After returning to the bureau, Li Jun called Sun Jianguo and me to the conference room and asked about the situation in detail. After hearing this, Team Li couldn't help but hammer the table hard: "I thought I caught a big fish, but I didn't expect to hit the two small fish on the door." ”

After calming down, he said thoughtfully: "The sodium hydroxide sold by Guo Chao may have been bought by the murderer, if it is used as a regular channel, it is completely directly bought from the store, and there is no need to sneakily buy dirty goods." ”

Sun Jianguo replied not very surely: "Not necessarily, I asked Professor Jin Weijia of Songhai University, according to him, sodium hydroxide is very well synthesized, and the baking soda and limestone needed are uncontrolled daily necessities, and the murderer may also synthesize it himself." ”

"And I think this line should be put down for the time being, there are too many sources of sodium hydroxide, and it is possible that the murderer bought it from other places and brought it to Songhai. Now it is time to start with the situation in the sewers and Liu Shuqian's interpersonal relationships, and at the same time, we must hurry up to find the remaining corpses. ”

I also think it should be like this, after all, sodium hydroxide is not a rare thing, the murderer can completely make himself, and he can't take the risk to buy it, and it is difficult to find valuable clues according to this clue.

Li Jun's eyebrows raised slightly: "The focus can be removed, but the two of them have to continue to investigate until the clues are completely broken." ”

Sun Jianguo thought about it and agreed, and then asked: "I think it's okay, have you had any other clues so far?" ”

"No new clues were found in the victim's social circle, and Ma Zhiyuan had some new results, and a little trace elements were found in the pile of meat slices in the morning, and after identification, it was finally found that there was a little pork, gunpowder, and cat hair. I judged that the knife used to dissect the corpse was a household kitchen knife, so there was pork residue on it, as for the cat hair, it may be that there was a cat at home, and the cat ran into the scene of the dismemberment in the process of dismemberment, and about the gunpowder situation, I suspect that the murderer may have been in contact with firecrackers and other firecrackers before the dismemberment. ”

I was not sure in the tone in which Li Jun spoke, and apparently he was not sure about the origin of some of the trace elements. However, gunpowder and cats were a key factor, and the victim disappeared on July 3 and survived for four days before being killed on July 7, and then the body was frozen before being dismembered. Traces of gunpowder were found in the minced meat, indicating that the murderer had been in contact with firecrackers from July 7 to July 13, and may have even set off firecrackers, so the scope of investigation was greatly narrowed.

After saying my thoughts, Sun Jianguo and Li Jun pondered for a moment and agreed with my idea, and I was immediately overjoyed, and I was finally recognized, and it was not in vain that I racked my brains to come up with the inference.

Li Jun said with a solemn expression: "The focus is on the eastern district of the city, if it is not put into the whole city to search, no matter which one sets off firecrackers for anything, it must be investigated, and according to the habit, there are generally only a few two or three people who set off firecrackers, mainly for these two and three people." ”

"Yes, I'll be in charge of investigating this matter." Sun Jianguo took over the task, and just as he was about to speak, there was a knock on the door to speak, and the voice was Liu Yefang.

Li Jun said a word of advancement, and when he saw her walk in, he joked: "Great psychologist, has the interrogation resulted?" ”

"I don't dare to be a turtle, but it's still a turtle in an urn to deal with these two people." Liu Yefang smiled bitterly, and then handed the transcript in his hand to Li Jun.

Li Jun took it and looked at it carefully, and read the seven or eight pages of the transcript for more than ten minutes, and then gave it to Sun Jianguo, who simply glanced at it and threw it to me.

Li Jun tilted his head and asked, "Are the two of them interrogated separately?" Did Guo Chao and Tian Ge's transcripts find anything incorrect? ”

Liu Yefang said affirmatively: "It was interrogated separately, and the confession was basically the same, but for the resale of medical devices, Guo Chao stopped all the blame, and Tian Ge didn't know what to do, and asked the reason that he said that he was raising a fetus at home, and his husband Guo Chao's matter was not clear." ”

"When the catastrophe came, they flew separately, and the couple can be regarded as a complete interpretation of this case. However, Guo Chao can do it, in order to prevent his wife from being imprisoned, he undertook all the crimes by himself. ”

Sun Jianguo lit a cigarette again, and looked at Liu Yefang with a complicated face: "Xiao Liu, do you think it is possible for them to collude?" ”

Liu Yefang frowned and thought for a few seconds, and said, "There should be no collusion of confessions, I don't think those two people are simple, what can they do?" Still can't escape jail? ”

"That's what I'm thinking about too much, and I'll take Xiao Xu to Chengdong District tomorrow to investigate."

There was nothing to say all night, and when it was more than eight o'clock, Sun Jianguo called me to go to the eastern district of the city, after a morning of investigation and visits, there was only one new store opened and firecrackers, coincidentally, the place where the firecrackers were set off was on Songhua Street, which was a newly opened restaurant.

"We are from the Municipal Public Security Bureau, where is your person in charge? We would like to know a little bit about it. ”

After identifying himself, a middle-aged man at the front desk hurriedly stood up and asked, "I am the owner of this store, may I ask the police comrade what is the matter with you?" Is it convenient to go to the back? ”

Sun Jianguo said with a smile: "Yes, it's just a small thing, not a big thing." ”

When I came to the back hall, Sun Jianguo motioned for me to ask, and he said to smoke a cigarette, so after sitting down, I took out a pen and paper and looked at the shopkeeper and asked, "Comrade, when did your restaurant open?" ”

The owner of the hotel replied without thinking: "At nine o'clock in the morning on July 9th, I deliberately went to the City God Temple to count a good day. ”

"How many firecrackers were set off that day? Where did you buy it? ”

"The firecracker shop in the north of the city bought more than 300 firecrackers."

I asked again, "How did the firecrackers come back that day?" Who has been in contact with them? ”

The shopkeeper thought for a moment and said, "I found a van to pull it back, and I unloaded the goods with the guys from the firecracker shop, comrade policeman, is there a problem with that batch of firecrackers?" ”

I didn't reply to him, but after recording the clues, I asked, "Do you remember the guy at the store?" Who were the people who set off the firecrackers on July 9th? ”

The shopkeeper thought about it for a few minutes, and finally replied slowly: "I still have a little impression of the guy in the shop, but I am not familiar with it, but I am quite familiar with the owner of the firecracker shop." There were a lot of people who came to eat that day, but there were only three people who set off firecrackers, one was me, and the other two were neighbors. ”

"Neighbors? Who is it? Hearing this, I suddenly figured out something, so I hurriedly asked.

"One is Xiao Zhang, the owner of the Starkey bookstore next door, and the other is the owner of Lianhua Supermarket, Liang Kezheng, I invited them over for dinner that day and asked them to help set off firecrackers."

Hearing this, I suddenly wanted to reason a lot, Liu Shuqian said that she was going to the bookstore before leaving the dormitory, and when this restaurant opened, the owner of the bookstore also came, which seemed to be a bit of a coincidence. Thinking of this, I continued to ask.

"What is the owner of Starck's bookstore? How do you get along with your neighbors? ”

"You said Xiao Zhang, well, this person is okay, but he doesn't like to talk much, he is very introverted, I heard that it was because the fiancée who talked about it a few years ago ran away with the coal boss, so he was listless every day, and he was depressed for several years. It's not good for me to see him like this, he's thirty years old, how can he be like this every day, there are so many women in the world, why do you have to hang yourself on a tree? ”

So he called him to come and have a meal and relax. I had dinner that day, and I saw that he was in a much better mood in the last few days, and he talked and laughed with his neighbors. ”

The shopkeeper said that his tone was a little relieved, and he seemed to be satisfied with his approach.
