After listening to Sun Yaozhang and Huang Limei's analysis, Zheng Wanjiang said: Your analysis is not unreasonable, but there is no evidence, and it is unlikely that He Jiaqi committed the crime. Think about it, if it was really He Jiaqi's uncontrollable emotions that caused He Jinqiang's death, then it was impossible for him to use such cruel means, why would he strangle him with a rope, if he was in a hurry and put him to death, but why cruelly disfigured He Jinqiang's face, is this possible? He can really do it, this is his biological son, there is no deep hatred between them, He Jinqiang's death time is after ten o'clock in the evening, there are at least three people in the family, the possibility of committing the crime is very small, it is impossible for them to watch the murderer, especially his mother, it is impossible to watch his wife kill the child.

Even if he was emotional and put He Jinqiang to death, then the family would definitely cause a panic. And how the body was transported to the Kangzhuang Bridge, he couldn't do it alone, so someone had to find out, this is also impossible, He Jiaqi is an old man in his sixties, and he is frail and sickly, he can't move He Jinqiang's body at all, not to mention that it rained heavily that night, which makes some sense.

In addition, according to the report of neighbor Cui Yunlu, on the evening of July 17, the He family did not find any abnormal phenomena, but at noon on the 16th, it was found that there was a quarrel in the He family, and He Jinqiang did not come back after leaving the house, which further ruled out the possibility that his father committed the crime, and the first scene of the murder should not be in the He family.

If the first scene was at He's house, but the neighbors reported that there was no quarrel in He's house that night, only the sound of TV, and there was laughter, which proves that there was no major conflict between them, and the quarrel between father and son is a normal phenomenon, and it will pass after a short time, and it is impossible to kill people for no reason. Therefore, He Jiaqi is not a murderer, and the He family is not the first scene of the murder, the first scene should be a place where He Jinqiang and the murderer are more familiar.

"There is another question, He Jinqiang's father and son quarreled at noon on the 16th, so where did he live at night? According to his apprentices, he did not live in the unit that night, and Li Qiulan did not know where he went, which should attract our attention. I wanted to search his dormitory, but there was no search warrant, and in case there was no problem, wouldn't we be passive, and young people nowadays are very law-conscious. But they won't be back until after eight o'clock in the evening, and I've made arrangements. Huang Limei said.

"It's good that you do this, go and investigate in the evening, ask these people directly about the situation, they have been in contact for a long time, they should know something about him, maybe they can get some clues." Zheng Wanjiang said.

"He Jinqiang came out of Li Qiulan's house at eight o'clock in the evening, he was killed after ten o'clock, so where did he go during this time, could it be that he went to meet someone, and drank together again, with the amount of alcohol that ordinary people drink now, two bottles of beer are not too much, but after testing, the alcohol content in his stomach is too high, indicating that he drank again in the future, so who will be the person who drank with him, it is possible that he is the murderer." Zheng Wanjiang continued.

"Li Qiulan and Cui Yunlu both reflect a situation that deserves our attention, that is, Wang Daqing, he is a figure in society, I know this, but there is no big illegal behavior, and it does not constitute a crime. He had a holiday with He Jinqiang, whether He Jinqiang's death had anything to do with him, all this needs to be further investigated, and who He Jinqiang was with after 8 o'clock on the night of his murder is very important to us. ”

"So how do we conduct an investigation? It is impossible to blindly run around like this all the time, which will waste our energy and delay a lot of time. Huang Limei said.

"There is no other way, we have to investigate from the people he knows best, and only then can we get some clues." Zheng Wanjiang said.

"What do we do now?" Huang Limei asked.

"From the analysis of various clues, the deceased has been determined to be He Jinqiang, there is no doubt about this, we will go to He's house again, do the work of his parents, let them tell the truth, and then go to He Jinqiang's room for an examination to see if we can find some clues." Zheng Wanjiang said.

"The key is that He Jiaqi doesn't cooperate with us, and there are some things that we can't figure out. What kind of person is he? Why don't you admit that the deceased is He Jinqiang, it's really a little incomprehensible. Sun Yaozhang said.

"What if they're still like last time? He really doesn't admit it, and we can't do anything about it, can't we detain him because of this? Huang Limei asked.

"If that's the case, it's forcibly inspected, and if he obstructs it to obstruct official business, Limei, you go through the relevant procedures, and check the people who have spoken to him in recent days one by one, it's impossible for them not to have been contacted, and they will start acting immediately." Zheng Wanjiang said decisively.
