Yin Daping wanted to interrupt Liu Dayu's words. The sea of bitterness is boundless, and now, Yin Daping's mood has returned to its original state: "Can you tell me first, how are you sure that the deceased is Che Rengui?" "Yin Daping is still a little unwilling, we have to admit that Yin Daping has done enough work on Che Rengui, he thought that what he did was seamless, in order to make Che Rengui disappear completely, he actually entered No. 157 again, it can really be said that the mechanism is exhausted!

"Okay, since you want to know, I might as well tell you, but only if you have—"

"Don't worry! Now that we have admitted that I did the case, I will explain the process of killing Cha Rengui in 1510, I have done what I have to do, and now, there is nothing to hide. It stands to reason that I have earned it, and I have nothing to regret. ”

"Good. We took a lot of detours and spent a lot of time and energy on this case, and the reason why we linked Cha In-gyu's disappearance to the deceased is mainly due to the landlord Cha Huating and the neighbors. Che Huating provided us with a more detailed information about the tenants, in this information, there is a person who has lived in No. 157 twice, the first time in the two wings in the east and the second time in the two wings in the west, and this person is you, Yin Daping, at first, you were excluded, according to the fact that if you were the murderer of Che Rengui, you would not be able to enter No. 157 again, because the time of Che Rengui's murder was around June 1990 - this is the conclusion of our autopsy. After all the residents have been eliminated by us one by one, our attention slowly falls on the residents of the 'surname Ma', and the reason why we focus our attention on you is that there are three important precursors: first, the time of the deceased's death and the time of Cha Rengui's disappearance overlap - in fact, the same time; Second, we learned about the background of some of the cases from our neighbours and former workers who worked as domestic helpers in the car. Liu Dayu looked at Che Huating and continued, "We learned that Che Rengui is the adopted son of the Che family, and the only son of the Che family was executed by the people's government in 1950, and after that, Che Rengui became the sole heir to the Che family's property. Thirdly, when the body of the deceased was assembled and spliced, the part connecting the kneecap and the calf bone became fragments - this is the first flaw you exposed, in the case of soft tissue wrapping, ordinary heavy objects cannot break the bone through the soft tissue - the murderer did not need to do more, because the dead's lethal source was in the head, and Che Huating inadvertently revealed to us a very important information, his father has a very prominent feature in physique, that is, the calf bone is longer than the thigh bone - The average person's lower leg bone is about the same length as the thigh bone. In this way, we naturally associate Che Rengui with the deceased, so we carried out DMA identification of the deceased, which is a new technology that has just been applied to criminal investigation work in 1993, through DMA identification, we know that the deceased is Che Rengui, who has been 'running away from home' for five years, you think you are extremely smart, you smashed the bones at the junction of the deceased's kneecap and calf bone, and took away a part, through this treatment, you changed Che Rengui's height from 1.73 meters to 1.71 meters. ”
