"We must first determine the identity of the murderer. After knowing his identity and his experience, I feel that the motive for the crime will be immediately clear." Lao Zhang said to me.

What he said makes a lot of sense, but now one clue we know is that the forensic doctor in our police station has a problem. Lao Zhang and I once suspected that he might be the real murderer, and there are no other clues. There is no evidence now, and to be honest, I still believe in the forensic doctor, so it is not easy to ask him to question him.

"Why did he hide these things from us before? I don't believe that with his level, he wouldn't know that Zhou Xing and Wang Zihan have male sperm in their bodies. I think he doesn't want to tell us, or what else he knows is that I and you two don't know?" Lao Zhang hugged his chest with one hand, touching his chin with one hand, thinking while telling me the questions he suspected.

"I think the forensic doctor may just be a matchmaker. He should not be the biggest murderer. He didn't tell us that he should have his own difficulties. What else can we say? We can only wait for him to tell us when he wants to say it, or we will question him after we have evidence." I told Lao Zhang about my guess.

"Why did you think like this? You talked to him before and asked him how did you ask? Did he say that? Did he say something to you?" Lao Zhang asked me.

I shrugged my shoulders and said that I didn't say anything. I told Lao Zhang my own opinion, "I said nothing. We are colleagues, and I didn't ask too much. After all, I still believe that he is a good person!"

"Since you said this, I have nothing to say, and what you said makes sense." Lao Zhang did not continue asking. He understood my considerations and believed in my judgment.

"This first case is a bit confusing. We can let it go for now, and then we will deal with the basic situation of the second phase of the case, and finally combine the two cases. The third case has nothing to do with the first two cases. Let's put it a confusing for now, and then go and see that case after these two cases are basically in sight." I said to Lao Zhang.

"Just like I thought, let's investigate the second case now." Lao Zhang found information about Li Xiao and Shangzhi from the stack of investigation reports on the cause of the victim's death, and then found the visit records made by Lao Zhang and me when I visited Li Xiao and Shangzhi's relatives and colleagues in his folder, as well as the archive records of Li Xiao and Shangzhi found by Xiao Wang. Lao Zhang and I first analyzed these information one by one, and continued to investigate when there are unknown places, so that we can break through the unknown places step by step.

"First of all, we know that it is the deputy section chief of Zibo Food Processing and Manufacturing Factory, Wang Houda, who specially hired two people Li Xiao and Shangzhi. After half a month, Zhou Xing and Wang Zihan also came to this Zibo Food Processing and Manufacturing Factory. Now we don't rule out that the four of them came to this factory one after another, but someone did it intentionally, instead of accidentally getting together." Lao Zhang first started to analyze it for me from the director of the Zibo Food Processing and Manufacturing Factory he entered.

"Yes! The first important point is that the encounter between the four of them may have been intentional." I summarized what Lao Zhang said.

"Let's look at it again. We visited the family of Li Xiao Shangzhi. We knew that Li Xiao's family was humble and knew that Li Xiao Shangzhi had an unusual relationship, but they drew a clear line with Li Xiao! The family of Shangzhi did not know the relationship between Li Xiao Shangzhi, but Brother Shangzhi knew it, and could see that Shangzhi's mother regarded this type of people as an alien, so Shangzhi concealed it. Later, we went to Li Xiao Shangzhi's factory and visited their roommates in the same dormitory. Everyone had a good impression of them. We also knew that Li Xiao was a relatively cowardly and gentle person, while Shangzhi was a person who was not particular about the details and had his own ideas. This is certain that Li Xiao Shangzhi's two are indeed homosexual. At the same time, they had a good relationship with Zhou Xing and Wang Zihan!" Lao Zhang analyzed the four of them for me.

"This is the second important point. The reason why Li Xiao, Shang Zhi, Zhou Xing and Wang Zihan have a good relationship is because they are all homosexuals, and they decided to use each other as a cover to continue the unusual relationship between the four people." I also summarized the situation that Lao Zhang analyzed to me, "But one thing worth noting is that this point just shows that their relationship has not been approved by both parents, so this is the worst solution."

"Yeah, that's true." Lao Zhang nodded and agreed with my point of view. He opened his notebook and displayed it in front of me, and saw it for me, "I have also recorded an important part of it. The relationship between Zhou Xing and Wang Zihan was known by the people in their dormitory, and Li Xiaoshangzhi has been staying for longer than the two of them, but they have not discovered it. Is there anything else we haven't noticed?"

"I really don't pay attention to anything? Look slowly! If there is really a problem, we will find out in the end." I shrugged my shoulders and said to Lao Zhang.

"Then the third point worth noting is here." Lao Zhang found the report on the cause of death of Li Xiao Shangzhi from the stack of documents that Jiang Dinghai took, and placed it on the table. We both saw it. Then he pointed to me, "The fatal reason written on it is exactly the same as what we often say when we go to the forensic doctor. They are all severely damaged in temples, resulting in deaths. Among these three cases, the forensic doctor only told us the truth that can be true, but the other cases are hiding us. I am doubting one thing. Is this second case not done by the first and third cases? And the person we forensic protects happened to be related to the first and third cases, and the second case has nothing to do, so he chose to tell us the truth. The reasons for the first and second cases he mentioned are all to mislead us. Do you think there is this possibility?" Lao Zhang asked me.
