"The words have been said here, so now the only suspicion is the grandmother." Xu Tian said.

"The point is that except for the night shift watchman who has just taken up his post, no one else can prove to Lao Ma that he took away his grandmother." Yu Yi said.

"Why do you have to find out the truth of this case? The grandmother's age and case can allow her to escape the punishment of the law, if this case is really done by the grandmother, even if you investigate the truth, it will not help, and the murderer cannot be arrested at all. Xu Tian said.

"Of course I know about this kind of thing, but I'm just suspecting that the old grandmother is the murderer, and I don't have any evidence that the old lady is the murderer." Yu Yi said.

"That is to say, this case is a headless case, I was not at the scene three years ago, I can't see the scene of the crime, there is no case file, just listen to you here, I really can't help you." Xu Tian said.

"I told you so much, just to ask you to help me analyze whether the old grandmother was taken out of the ancestral hall by the old horse." Yu Yi said.

"Since you have already said that the ancestral hall was brightly lit on the night of the crime, and it was not until midnight that the murderer hid in the dark and attacked the police officer who was secretly staring at the stage, in this case, what else can I say?" Xu Tian said.

"You still don't understand what I'm saying." Yu Yi said.

"You want me to help you analyze the case, but you yourself have no sincerity at all, in this case, why are you embarrassed to ask me to help you analyze? Also, you obviously already have the answer in your heart, why didn't you find out the murderer back then? Xu Tian asked.

"I just can't believe that the person I suspect is suspected of murder." Yu Yi said.

"How can you conclude that the man is not suspected of murder? This matter may not have any effect on you, but your dedication to this case is very large, so it can be seen that you are lying to me, at least you have not told me all the truth, and your style of doing things like this is not sincere for me to help you analyze the case. Xu Tian blamed Yu Yidao.

"Lao Chen really didn't see the wrong person, just by saying these words, I can judge that I have something to hide from you, you do have a strong talent in logical analysis." Yu Yi said.

"It's not hard for me to tell you that you're lying, because I know that grandma can't be a murderer, and you've been biting her all the time, and it's obvious that you want to know the truth of the case, but you're biased in favor of the suspect you suspect in your heart. Even if the old grandmother has the motive to kill, she does not have the strength to kill, how can a seventy-year-old woman kill a young man who is in the prime of life? What's more, there was a big loophole when the fourth case occurred, who was the person who placed the amplification equipment in the ancestral hall? This is obviously a great clue to track down the murderer, but you make a big detour and tell the suspect that he is missing. Xu Tian said.

"I didn't hide this from you, the fingerprints on the PA equipment are indeed the last prospective groom in the village, but he is missing, as if someone told him the results of the police's fingerprint comparison, which also makes me feel very unbelievable." Yu Yi said.

"Police! There is no doubt that there are police people interfering in this. Xu Tian said.

"But I don't understand, why would the police people do such a thing here? And it simply doesn't make sense. Yu Yi said.

"There is only one suspect, the one who was attacked by the murderer, can you think of the possibility that someone else committed the crime?" Xu Tian asked.

"You're right, this case does look very simple, after the two local police officers who were attracted to the front hall of the ancestral hall by the amplification equipment left, the police officer who was secretly staring at the stage can act recklessly, he can catch the victim and kill him, and then disguise himself as being attacked by the murderer, and when the two local police officers come back with the megaphone, he will stand up with his head covered and pretend to be stunned." Yu Yi said.

"If there are no other clues to guide the murderer's movements, then this answer is the most logical truth." Xu Tian said.

"But there was nothing suspicious about the police officer at that time, first of all, he was sent to this island to carry out a mission, he had nothing to do with the people on this island at all, and his hometown was in Dong'an City, and his hometown and ancestors were all natives of Dong'an City for three generations. He was a qualified police officer, had never committed discipline and had no motivation to commit crimes on the island. Yu Yi said.

"I suggest that the officer be re-investigated, this is very important." Xu Tian said.

"It's useless, two years ago, a year after the case, I proposed this idea to Lao Chen, and Lao Chen also helped me investigate the police officer, of course, Lao Chen investigated secretly. Last autumn, I put forward the idea of investigating the police officer to Lao Chen, who was very angry at that time and quarreled with me, and the police officer was the backbone of Lao Chen's team at that time, and at my strong request, Lao Chen still launched an investigation against him. Yu Yi said.

"Coupled with the investigation of the police officer at the time of the crime, you have already investigated him three times, right?" Xu Tian asked.

"Four times, and this fall, two months ago, I asked the police to investigate him again." Yu Yi said.

"Nothing was investigated?" Xu Tian asked.

"He is an excellent police officer, upright, and Lao Chen's right-hand man." Yu Yi said.

"Is the officer you're talking about on the island now?" Xu Tian asked.

"Lao Chen didn't let him participate in this operation." Yu Yi said.

"Then the officer can only be listed as a suspect for the time being, and we will have to find him again when we leave the island, and this time I hope to be questioned in front of him, just asking." Xu Tian said.

"I'm afraid this matter is not that simple, if we can be sure that he is the murderer, it is okay, once we investigate and find out that it is an oolong incident, then we will no longer be able to interfere in the case of Nian Tai Sui." Yu Yi said.

"This is inevitable, for the sake of prudence, it is better for us to go and put the grandmother first, I have some things to say to the grandmother, and there are some questions to ask the grandmother." Xu Tian said.

"We have the same idea, so now there is still an hour and a half, let me take you to the ancestral hall to have a look! By the way, I will tell you a few things about the grandmother and this ancestral hall. Yu Yi said.
