"Yes, Che Huating's wife said the same thing. She rarely comes to number 157, but she does, so she has a little impression. Director Gu said.

"When did Che Huating's mother and wife see a large pile of bricks?"

"The old lady said that she saw the pile of bricks around 1970; Che Huating's wife said that the time she saw the pile of bricks was in 1987 when the old man assigned No. 157 to Che Huating. ”

Ouyang Ping stood up: "Let's go, let's go to the courtyard and have a look." ”

Everyone has been stationed in No. 157 for a relatively short time, and they haven't had time to pay attention to the environment of No. 157.

Liu Dayu picked up the flashlight from the coffee table and followed Ouyang Ping out of the door of the living room.

On the west side of the yard there is a separate house, which is the kitchen, and the area of the kitchen is about five square meters. On the south side of the kitchen, there are 50 centimeter-high black tiles, which look like they are some years old, and the small tiles on the side are very damaged, and the small tiles on the surface are covered with moss. There is also a small pile of broken bricks next to the small tile.

The bricks used for the first wall must have come from the large pile of bricks that the mother-in-law and daughter-in-law said.

Did the first and second walls, especially the first wall, be built first by the Che family, or by the tenants? This is a very important issue, if the Che family built it first, then the murderer may be the Che family, it stands to reason that the Che family is unlikely to hide the body in their own house, but contact the Che family to separate No. 157 from the Che family compound and rent out the house, which is very arguable; If it is added by the tenants, then the murderer must be hidden among those tenants, and once the problem is clarified, the scope of the investigation can be determined—and the scope of the investigation will be much narrower.

If this issue is not even clear, then it will be difficult to investigate this case further.

The problem is that this is most likely an unsolvable equation, first of all, the person who is most likely to know about this situation, Cha Renguiren, has no shadow of the top of his hat. The comrades could no longer count on him; Moreover, the boss of the car may not know the situation, if the case is related to the car family, then, even if the boss knows the situation, he will not say it; Secondly, among the many tenants, there are several families who rent four side rooms, and they are a family behind closed doors, and there is such a big case, even if someone does something on the wall, it will not set fire to the body, the point is that during the period when some tenants lived in No. 157, some houses were idle, and it didn't take long to kill people, and it didn't take long to hide the body in the brick wall, in this case, it was difficult to know if the body was hidden in the brick wall of the empty house. Che Huating's mother said that in her impression, there used to be a large pile of bricks in the southwest corner of the courtyard at No. 157, and now, there is not much left of this pile of bricks, could the bricks used in the first wall come from that pile of bricks? This is very likely, and if this is the case, all you need to do is get a few bags of cement and lime from the outside, and the materials for building the wall will be available. The three families living south of 157 are not easy to detect.

To find valuable clues, comrades still need to spend a lot of time and do a lot of work.

"Let's go, let's go to Mrs. Li's tea stove to fetch water." Ouyang Ping said.

Liu Dayu stood up; "Let's go, I'll go with you."
