Liu Dayu continued: "From the beginning of the intervention in the case, we didn't think that the deceased was Che Rengui, in order to eliminate all traces of Che Rengui on the deceased's body, you also extracted two tiger teeth from the deceased's mouth and replaced them with two ordinary teeth, after DMA identification, those two teeth are another person's teeth." The reason why you want to eliminate all the traces on Cha Rengui's body is to lead the police investigation astray, because you know that as long as the police know that the deceased is Cha Rengui, it is possible to know who the murderer of Cha Rengui is? Because it's a vendetta murder. ”

"There is another situation, we can also tell you, when we were confused in our hearts and lost the direction of criminal investigation, forensic expert Guo Changping gave us guidance, that is, he helped us to recover the shadow of Che Rengui from the body of the deceased, and he even concluded from the teeth and bones of the deceased that the murderer was probably an orthopedic surgeon - at least a dentist. By now, you should understand how we suspected you and found you. There is another very important situation, we can also tell you, your grandfather Che Renju's childhood playmate, classmate and good friend revealed to us a very important situation, in 1950, that is, before Che Renju's accident, there was a woman holding a child who went to him to inquire about Che Renju's situation, this woman is Cha Renju's wife, your grandmother Yin Zhuojun, but your grandfather did not meet him, and the reason why your grandfather took off his military uniform and left your grandmother was afraid of affecting her. At this point in the investigation, we have a general understanding of this case. This is clearly a family vendetta. ”

Che Huating also has an overall understanding of the case: "Captain Liu, are you saying that Uncle Renju's death is related to my father?" ”

"Yin Daping, this question should be answered by you."

"It was your father, Che Rengui, who denounced my grandfather Che Renju to the government, not only did he denounce it, but he even bribed Deputy District Chief Li to put my grandfather to death by the hand of Deputy District Chief Li, and finally found a position as the chairman of the Chamber of Commerce in the district government - and turned him into a state cadre." Yin Daping knows a lot of things.

"I don't understand, my father, why did he do this?"

"He occupies the magpie's nest and wants to monopolize the property of the Che family. My great-grandfather couldn't stand the blow of my grandfather's repression by the government, and he couldn't afford to fall ill, so he died soon after, and soon after, my great-grandmother also passed away. For so many years, from my grandmother to my parents, and then to me, my grandfather's death was like a mountain, which overwhelmed us, because my grandfather was suppressed by the government, my grandmother was criticized by the Red Guards, paraded in the streets, and finally jumped into the sea with hatred, my father signed up to Xinjiang to support the border in order to get rid of the entanglement of fate, he wanted to be a soldier, but he couldn't pass the political trial, he wanted to recruit workers, but he couldn't pass the political trial, Even if he wanted to be the captain of a production team, he passed the threshold of not being politically examined. ”

"Captain Liu, is what he said to you true?"

"It's true."

"To tell you the truth, I originally wanted to do something that was not good for the four of you brothers and sisters, do you know why I stopped?"

"Why?"

"Because your mother is different from your father, she has a good reputation among the neighbors, she does good deeds and accumulates virtues, eats fasts and recites Buddha all day long, she is atoning for Che Rengui."
