Xu Dayuan lit a cigarette and asked the director:

"The courtyard of the Wang family, as well as the small second floor inside, looks like it has been around for some years, when was it built, you always know, right?"

The director pointed to the inside of the courtyard door, and several people followed.

"We have a habit here, when our house is built, one is to tie a red cloth to worship when the beam is up, and the other is to carve the year of the house yard on the stone behind the door.

Look here, their house was built in 1983, the house was also built at that time, the foundation is particularly deep, it is a house built by a professional construction team from the city, not just a few bricklayers, and the courtyard wall is also higher than the average house, three meters. ”

Zhou Ning didn't listen any more, these were not helpful to the survey, and said hello to Xu Dayuan, and entered the small second floor of Wang Hongzhan's house, and as soon as he came in, he saw Yang Xuetong carrying a box down.

"Didn't find it?"

Yang Xuetong shook his head.

"There are four bedrooms upstairs, the easternmost bedroom has traces of previous investigations, I asked the local investigators, this is the room where the deceased He Dongmei lived, the quilts and clothes placed in it are all summer, and the two trolley boxes on the ground are diapers and change of clothes, and the cabinets are useless.

As for the other rooms, both the furniture and the beds were covered with old sheets, and it seemed that no one lived in them all year round, so we checked around and moved the furniture away, and found no hidden safes, or places like the mezzanine of the walls, and the boxes and cabinets were basically empty. ”

Zhou Ning frowned, in fact, when he took over this case, Zhou Ning was familiar, because in the books provided by the previous system, there was a similar case.

It was also a woman who was killed at home with her child, and the child was drowned in a water tank, and when the police found it, a pair of small feet of the child were floating on the water, even if it was a text description, it was shocking.

The woman's identity is the same as He Dongmei, she is a rural teacher, she hid gold bars at home and was seen by the children who made up the class, and a child went to steal in the middle of the night and was found by a woman, and then the woman was killed and the child was killed.

For a time, Zhou Ning was affected by that case, and he also thought in this direction, but there is a clear difference between the scenes of the two cases, and the people who come in from the north window of the kitchen will definitely leave traces, after all, the window is narrow and there is thick grease, but the two deceased are clean and there is no residue.

Climb over the wall to come in, it is also denied, the wall of this courtyard is as high as three meters, it is impossible to come by hand, borrow tools, and leave traces on the broken glass on the wall, and the sound will be very loud, and now the only way left is the gate.

Zhou Ning looked at Yang Xuetong and said:

"Ask Bai Hua and Captain Zhang, when they came to the scene, did they break in? Is the lock kept? In addition, are there any traces or substances left on the key, and have the fingerprints and DNA been collected on it? ”

Yang Xuetong's eyes lit up, and he quickly nodded and ran away.

Zhou Ning walked towards the room on the west side, and as soon as he came in, he saw Da Zhao kneeling on the ground with his buttocks, and Zhu Xingxing was helping him hold a strong flashlight on the side, not knowing what to look for in the corner.

"Did you find anything?"

Da Zhao raised his head suddenly, and the back of his head directly touched the top of the cabinet, and there was a bang, and Zhou Ning felt pain when he heard it.

"Be careful, are you okay?"

Da Zhao climbed out from under the cabinet, ripped off his gloves and rubbed the back of his head, and complained to Zhu Xingxing:

"If you don't say Zhou Xiaozhou is here, it will scare me!"

Zhu Xingxing raised his leg and shouted:

"You don't throw the pot on me, I don't know how big I am, I said I climbed in to see, you have to see it yourself, kowtow and rely on me."

Zhou Ning didn't participate in the daily life of these two people, coughed, and came closer, only to find that the part that Da Zhao climbed into was a cabinet similar to a chest, but it was extremely long, and one wall was full of this cabinet.

There was an incense burner and a few saucers on it, and it seemed to be fruit and steamed buns, but they had dried completely, and some of them had turned into black pieces of charcoal.

With a slight shake of his hand, Zhou Ning found a problem, this cabinet seemed to be inlaid into the wall.

"Is there anything behind the cabinet?"

When Da Zhao heard this, he was a little discouraged.

"I've checked it all over, and I didn't find anything special, just this cabinet, it's all drawers, I took out the drawers, and there was actually nothing in them, but the wall behind me knocked on it, and the sound was hollow."

Zhou Ning squatted down and took a closer look, and sure enough, there was a wall behind the cabinet, but he didn't see any hidden small doors, or bricks that could be moved.

Zhou Ning waved his hand, motioned for Da Zhao to get up, withdrew from the room, and observed that the wall of the inlaid cabinet was adjacent to the location of the living room at the entrance.

There is a small room side by side on the north side, which looks like it should be a storage room, but there is nothing in it, and the area is only thirteen or fourteen square meters.

Zhou Ning stretched out his hand towards Da Zhao and said:

"Give me a tape measure."

Zhu Xingxing found the tape measure and sent it to Zhou Ning, Da Zhao struggled to get up from the ground, and kept patting the dust on his body, after all, there had been no one living here for a long time, and the dust was quite thick.

Zhou Ning measured the distance between the things in the storage room, and then measured the distance between the things in the room where Da Zhao was located, and when he saw the value, Zhou Ning didn't speak, and Da Zhao came over.

"What's wrong? What's the problem? ”

"The distance between the two rooms is different from east to west, but from the outside, there is no difference in the width of the two rooms."

Da Zhao stared at his small eyes and rushed directly to Zhou Ning's side.

"It's a little different, this is possible, after all, how much worse are the houses built in the village?"

"Twenty-two centimeters."

"So much, is there a mezzanine in the walls of this room?"

Zhou Ning didn't speak, turned around and came to the living room, on the other side of the wall, there were four bookcases of the same height and size placed side by side, full of books, Zhou Ning probably took a look, these are not anything, it seems that they are Wang Hongzhan's textbooks from childhood to adulthood.

The arrangement is quite neat, from elementary school to graduate school, all kinds of books studied, the upper part of the bookcase is transparent glass, the lower part is a wooden door, you can feel that the material of this bookcase is quite good, and it is also very old.

Zhou Ning walked over and opened the cabinets above and below the bookcase, only to find that all the bookcases were books placed on them, and there were only a few paper rolls placed below.

Da Zhao changed his gloves, opened the paper roll and looked at it, there were various awards inside, each of which was separated by newspapers, some of which were very old.

Obviously, this was not done by Wang Hongzhan and He Dongmei, it can be seen that the parents of the Wang family are very concerned about Wang Hongzhan's education, and there is nothing to be found in a few paper rolls, so Da Zhao hurriedly restored the things and put them in the room.

Zhou Ning stood in front of the bookcase, and at present, he saw that there was a problem with this wall.

He squatted down, looked at the cabinet partition below, reached out to remove the partition, and Da Zhao leaned over, holding a strong flashlight, carefully illuminating the corners of the cabinet.

When he checked the fourth bookcase, Zhou Ning hadn't touched the partition yet, and saw that there were two wooden strips on the edge of the wooden board behind him, the wooden strips were light-colored, with a few black dots on them, just across the edge of the back panel, and the position where the strong flashlight shone through, he found that there was a gap on the edge of the back panel.

Zhou Ning was so excited that Da Zhao wanted to reach out and grab the partition, but Zhou Ning stopped him.

"Don't worry, Zhu Xingxing will call Lao Yang and them over, Da Zhao will take fingerprints on this partition, as well as the wooden strips and the back panel, collect samples, especially the wooden strips, and spray luminol reagent, there are black spots on the wooden strips, I suspect it is bloodstains."

Da Zhao came to the spirit, dragged Zhou Ning to the side, and looked at the ground, there were no footprints Compared with the surroundings, the ground here is a little thinner, and the boundaries are clear, which are traces left by rubbing.

Da Zhao took a photo, and then padd the survey pad, knelt directly on it, brushed the partition, and the traces left by two thumbs appeared on the left and right, obviously, this is the action of grabbing the partition, then there are naturally fingerprints of other fingers below, and Da Zhao is lying directly on the ground.

Judging that there was no problem, there were also fingerprints left underneath, but what made Da Zhao a little disappointed was that the fingerprints were the fingerprints of latex gloves, and no fingerprints were left, but this discovery had already made Da Zhao excited.

Holding luminol and spraying it carefully on the fingerprint, the middle of the fingerprint clearly appeared in the original fluorescent area, and Da Zhao removed the partition.

Yang Xuetong and the others had already run quickly, and when they saw Da Zhao's posture, Yang Xuetong also quickly knelt and approached, and Sun Gaotie put the partition on the physical evidence bag on one side.

Da Zhao sprayed luminol reagent on the small wooden strip, and sure enough, the two black dots pointed out by Zhou Ning were bloodstains, and Da Zhao looked back at Zhou Ning.

"I'm open!"

"Hurry up and stop the ink."

Without waiting for Zhou Ning to speak, Zhu Xingxing didn't hold back and shouted first.

Yang Xuetong couldn't help laughing, he and Da Zhao grabbed a small wooden strip, twisted it slightly, and as the wooden barrier was removed, the partition behind it bounced directly to the outside.

Da Zhao's hand was fast, and he quickly caught the back panel, so that the things behind him were exposed, Yang Xuetong opened his mouth wide in surprise, Zhou Ning's angle could not be seen, he was a little anxious.

"What's in the back? Is the wall hollow? ”

Da Zhao handed the backplate to Zhu Xingxing, and then made way to investigate the position of the backing plate.

"There's an old-fashioned safe embedded in the wall, I don't know if it's in disrepair, one side has collapsed, and it's probably because of this that when I hit the other side, I made a hollow sound."

Hurriedly collected all kinds of information on the safe, found bloodstains and a few glove prints, looked at a pair of combination locks, and keyholes Yang Xuetong made a difficulty.

"We can collect the fingerprints on the safe, but who can open this thing, and it's such an ancient style, just find a lock, I think it's enough, right?"

Da Zhao waved his hand, looked indifferent, and kicked Yang Xuetong's shoes.

"You get up, I have a way."

Yang Xuetong hurriedly got out of the way, Da Zhao took half a step back, and kicked towards the upper left corner of the safe, with this action, the side that was originally upturned fell down with a click, the safe tilted forward, and Da Zhao smiled.

"There's nothing you can't do with a flying kick, if you can't, then do it again!"
