Although the DMA identification results have not yet come out, Ouyang Ping and Liu Dayu have already reached a preliminary conclusion: it is very likely that the deceased is Che Rengui. Cha Rengui died in his own wing. Number 157 is for rent—there is nothing but the house, so it doesn't feel like a money killing, it doesn't look like a love killing, it's a bit like a vendetta killing.

Now that we look at what Director Gu once said, the possibility of vendetta is even greater. Cha Rengui is romantic, he can't walk when he sees a beautiful woman, and he has also done a lot of hurtful things, so he must have a lot of enemies.

On the way back to No. 157, Ouyang Ping and the Che Huating brothers had a very important conversation.

The conversation revolved around four topics:

First, about the time when the surname Ma rented No. 157 and the time when Che Rengui 'ran away from home'. This topic was brought up by Boss Che, and last time, Boss Che only mentioned the matter of his father's 'running away from home', without mentioning a specific time.

According to the serious memories of the Che Boss and Che Huating brothers, the result is that the time when Che Rengui 'ran away from home' coincided with the time when the surname Ma rented No. 157, and in the memory of Che Boss, his father 'ran away from home' at the end of September 1989, while the time when the surname Ma rented No. 157 was from September to November.

Second, during the two rentals of No. 157 surnamed Ma, there was no vacancy in other houses (the first time surnamed Ma rented two east wings, and the second time he rented two west wings).

Third, when the surname Ma rented No. 157, who collected the rent? Whether Che Rengui and the surnamed Ma have any contact (contact has the conditions and possibility of being killed; Ouyang Ping, who was meticulous, remembered what Che Huating said: The wife surnamed Ma is very beautiful and dressed very fashionably, such a woman will not be indifferent to Che Rengui, who is amorous and can't walk when she sees a beautiful woman. Woman maybe a decoy)?

Fourth, what is the person surnamed Ma, what kind of accent is he speaking, and whether there is any information leaked out of the conversation and communication (it is indeed difficult to find the surname Ma, and now, if you want to find the trace of the surname Ma, there are two paths, one path is to find clues from Che Huating's memory - judging from the information provided by Che Huating, he must have had contact with the surname Ma, do you remember?) Among all the tenants, only this surnamed Ma and Che Huating authenticated the rental agreement - it can be said that it was because of this rental agreement that Ouyang Ping did not suspect him; Another path is to look for clues from the historical background of the case, among the people Cha Rengui came into contact with, who may be the murderer of Cha Rengui? ）。

On the way back to No. 157, the car boss once said: "I really let my mother say it." ”

Ouyang Ping caught this sentence in time: "What did your mother say? ”

"She said that sooner or later my father would be punished. Now it seems that my mother's words have been fulfilled. ”

An important content should be added here: On the way Ouyang Ping sent Guo Lao home, Guo Lao had a very important reminder: "Judging from the modus operandi and routines of the crime, the murderer is very likely to be an orthopedic surgeon, at least a dentist. Because only a dentist can find two teeth of the right size, and only a dentist can pull out the two tiger teeth in the mouth of the deceased, and only an orthopedic surgeon can come up with a way to smash the bones and change the height of a person. ”
