"I can only ask about the relationship between the driver and the victim, the most important thing is to figure out the relationship between Yan An and Yi Shuai, and now the two sisters Hailan and Haiqing can't ask normally, so we can only understand Yi Shuai through this driver who connects Yan An and Yi Shuai." Xu Tian said.

"But the modus operandi of the two cases has not yet been clarified, if we rashly ask the driver, will we be surprised? After all, we don't have any evidence against the murderer, and once the murderer is a bus driver, we are passive. Lao Chen said.

"Don't worry, after the driver is arrested, you just need to do what I say, just ask about the relationship between Yan An and Yi Shuai, and don't ask the driver too much about other things."

"You seem to be very confident? Do you think the driver won't be the murderer? ”

"I do think so."

"Can you give me a reason?"

"Judging from the scene of the two crimes, the main common denominator is the half-hidden door, and there is no trace of the two doors being pried, I think the perpetrator should be someone who is more familiar to the victim."

"Then why not the driver?"

"Because of the motive for the crime, I think the driver is just a matchmaker, and there should be no motive to kill Yan An and Yi Shuai."

"Why are you so sure?"

"Because Yi Shuai's death scene is a little different, judging from the dust on the ground in Yi Shuai's house, no one has entered Yi Shuai's house on the surface, which is very important; The scene of Yan An's death is different, Yan An may have opened the back door for the murderer himself, or the murderer may have entered the kitchen first and opened the back door for Yan An. Comparing the two crime scenes, we can find one of the most important problems. ”

"I understand, you think the murderer may be someone close to Yi Shuai, right?"

"This is very likely, because Yi Shuai's death scene gave us a very important hint, the murderer seems to be telling us that no one has entered Yi Shuai's house, but the murderer did not set Yi Shuai's death scene into a secret room, what does this mean?"

"No matter how you look at it, it's the murderer who is provoking us."

"I couldn't agree more, but I think there's something else."

"What is it?"

"I think it's because the killer can't close the door, or because the killer wants the body of the deceased to be found by others sooner."

"But ......"

"I know what you're questioning, there's no need to do this at the scene of Yan An's death, because there will definitely be hotel employees entering the kitchen the next day; But Yi Shuai's death scene is different, if the murderer does not ajar the door is not ajar, Yi Shuai's body may not be found for a long time, even in summer, the body will not be found by others soon, unless Yi Shuai has been dead for a long time before the smell of the corpse will be dissipated to the neighbor's house. ”

"Then your inference is that the murderer wants Yi Shuai's body to be found sooner?"

"From the current indications, this is very likely, but I can't overdo it, because there is no evidence that my inference is correct."

"What a headache, what about other inferences?"

"Other? The death of Yi Shuai and Yan An can also explain the psychology of the murderer, why did the murderer kill Yi Shuai and Yan An in the same way? The way the two men died looked like they were playing an indecent game, but I think it could be a trick on the part of the murderer. ”

"What do you say?"

"Because the murderer did it too deliberately, first of all, Yan An, we found some scars on Yan An's body, and those scars were all injured by kitchen tools, which shows that the murderer did not carry other tools except for the rope that tied Yan An's hands and feet before committing the crime, but Yan An was injured by the murderer again, judging from this indication, it seems that the murderer was playing a game with Yan An at the time, but the murderer really couldn't do the most important link, so the murderer's deliberate beating of Yan An was obviously exposed; The second is Yi Shuai, when we found Yi Shuai's body, we only saw Yi Shuai's neck hanging a scale, but Yi Shuai had no other scars on his body, which can also illustrate a problem, the murderer deliberately created the illusion of playing games with Yi Shuai, why didn't the murderer beat Yi Shuai? It shouldn't be difficult to find tools suitable for making games in Yi Shuai's house, but the murderer still didn't do anything, just hung a scale around Yi Shuai's neck, which shows that the murderer should not be able or unable to do anything else at that time. Xu Tian analyzed.

"Can't do anything else? I'm a little confused, what's your inference? ”

"It's the dust on the ground, if the murderer uses too much force, he will definitely make traces in Yi Shuai's house. But judging from the murderer's murderous methods, I think it doesn't matter if the murderer left traces in Yi Shuai's house, since the murderer wants Yi Shuai's body to be found by others sooner, why can't the murderer make traces in Yi Shuai's house? It's not logical to think about this, but the murderer must have a reason for doing so. Imagine that the murderer does not want to leave too many traces in Yi Shuai's house, but also wants Yi Shuai's body to be found by others sooner, from these two points, the murderer's behavior should be very clear. ”

"I think the murderer should be afraid that his own traces will be identified."

"That's right, so I deduced that the murderer who killed Yi Shuai should be Yi Shuai's acquaintance, and the murderer will be found out by us as long as he leaves a little trace, so the murderer does not dare to beat Yi Shuai after killing Yi Shuai, and can only symbolically hang a scale on Yi Shuai's neck, as long as we look like Yi Shuai's cause of death is similar to the purpose of the murderer."

"According to what you say, the person who can't leave too many traces at Yi Shuai's death scene should be Yi Shuai's family, right?"

"Have you noticed that too? Although I am very suspicious of Hailan, Hailan has an alibi, and I have already excluded Hailan, but Hailan acted in such a play in the police station, which inevitably made me doubt Hailan again. ”

"We have asked Hailan's classmates, and from yesterday to this morning, Hailan has indeed not left the school, and the murderer cannot be Hailan. and Hai Qing We have also investigated, Hai Qing has been receiving treatment, it can be said that Hai Qing's personal freedom is controlled, and she is even less likely to come out to commit crimes. ”

"Then we should start the investigation with Yi Shuai, I believe that we will be able to find out the person who is close to Yi Shuai, and that person is undoubtedly the murderer."

"It's almost time." Lao Chen looked at his watch. "Li Ming should be able to bring the bus driver back soon, let's go to the interrogation room and wait!"

"Dr. Lin, did you make an appointment for me? We're going to be sure to go to Dr. Lin tonight. ”

"Don't worry! I'll call Dr. Lin. ”
