Chapter 287 Safe Deposit Box

Xu Dayuan lit a cigarette and asked the director:

"The courtyard of Wang's house and the small second floor inside seem to be old. When it was built, you always know?"

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 sacrifice when the beam is erected, and the other is to engrave the year when the house was built on the stone behind the door.

Look here, their house was built in this courtyard in 1983. The house was also built at that time. The foundation was very deep. It was built by a professional construction team from the city. The wall is also higher than the average house, a full three meters. "

Zhou Ning didn't listen any more, it didn't help the investigation, so he greeted Xu Dayuan, and then entered the small second floor of Wang Hongzhan's house, and as soon as he entered, he saw Yang Xuetong coming down with a box.

"not found?"

Yang Xuetong shook his head.

"There are four bedrooms upstairs, and the bedroom on the easternmost side has traces of previous surveys. I asked the local investigators. This is the room where the deceased He Dongmei lived. The quilts and clothes in it are all summer. The trolley case is full of diapers, milk powder and a change of clothes, and the cabinets are useless.

As for the other rooms, no matter the furniture or the bed, they are covered with old sheets. It seems that no one has lived in it all year round. We checked around and removed all the furniture. We did not find any hidden safes or interlayers in the walls. Classes, the boxes and cabinets are basically empty. "

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

It was also a woman who was killed at home with her child, and the child was drowned in the water tank. When the police found out, the child's small feet were floating on the water. Even the text description was shocking.

The identity of the woman is the same as that of He Dongmei. She is a rural teacher. The children who made up classes saw the gold bars hidden in the house. A child went to steal it in the middle of the night and was discovered by a woman. Then the woman was killed and the child was silenced.

Once Zhou Ning was affected by the case, he also thought in this direction, but the scenes of the two cases are obviously different. People entering the north window of the kitchen will definitely leave traces. After all, the window is narrow and there are thick windows. Grease, but the bodies of the two deceased were clean without residue.

Entering over the wall was also denied. The wall of this courtyard is three meters high, and it is impossible to come over with bare hands. With the help of tools, rice noodles are required to leave traces on the broken glass on the wall, and the sound will be loud. Now the only way left is, It is the gate.

Zhou Ning looked at Xuetong Yang and said:

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

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

Zhou Ning just walked towards the room on the west side. As soon as he came in, he saw Da Zhao kneeling on the ground with his buttocks up. Zhu Xingxing was helping him hold a bright flashlight, and he didn't know what to search for in the corner.

"Have you found anything?"

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

"Be careful, are you okay?"

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

"If you don't tell Zhou Xiaozhou is here, you'll scare me!"

Zhu Xingxing kicked his leg, stared and shouted:

"Sir, you throw the pot at me and ask me. I don't know how big I am. I said I'll crawl in to see it. You have to see it yourself. Kowtow and blame me."

Zhou Ning did not participate in the daily confrontation between these two people. He coughed and leaned closer, only to realize that the part that Da Zhao climbed into was a cabinet similar to a drawer, but it was extremely long, and one wall was covered with this cabinet.

There is an incense burner and a few dishes on it. It seems to be fruits and steamed buns, but it has been completely dried, and there are some things that have turned into black pieces of charcoal.

With a little shaking of his hand, Zhou Ning discovered the problem. The cabinet seemed to be embedded in the wall.

"Is there something behind the cabinet?"

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

"I've checked it out, but I didn't find anything special. Just this cabinet, it's full of drawers. I took out the drawers, but there wasn't anything inside. But when I knocked on the wall behind, it sounded hollow. "

Zhou Ning squatted down and observed it carefully. Sure enough, there was a wall behind the cabinet, but he didn't see any hidden doors or movable bricks.

Zhou Ning waved his hand, signaled Zhao to get up, exited from the room, observed for a while, and found that the wall inlaid with the cabinet was adjacent to the entrance living room.

There is a small room side by side on the north side, which seems to be a storage room, but there is nothing in it, and the area is only [-] or [-] square meters.

Zhou Ning reached out to Da Zhao and said:
"Give me the 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, no one lived 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 and the others were. Seeing the value, Zhou Ning didn't speak, and Da Zhao came over.

"What's wrong? What's the problem?"

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

Big Zhao stared round his small eyes, and ran directly to Zhou Ning's side.

"There's a little difference, but it's possible. After all, how different are the houses built in the village?"

"22 centimeters."

"There are so many, is there a mezzanine in the wall 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, and they were full of books. Wang Hongzhan's textbooks from childhood to adulthood.

The books are arranged neatly, from elementary school to postgraduate, the upper part of the bookcase is made of transparent glass, and the lower part is made of wooden doors. It can be felt that the material of this bookcase is quite good, and it has been around for a long time.

Zhou Ning walked over and opened the upper and lower cabinets of the bookcase, only to find that all the bookcases were filled with books on top, while there were only a few rolls of paper underneath.

Da Zhao changed his gloves, opened the scroll and took a look. Inside were various awards, 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 Wang's parents are very concerned about Wang Hongzhan's education. There was nothing found in the scrolls, so Da Zhao hurriedly restored the things and put them in the room.

Zhou Ning stood in front of the bookcase, and now it seems that there is a problem with this wall.

He squatted down, looked at the partition of the cabinet below, and reached out to remove the partition. Big Zhao came over, holding a bright flashlight, and carefully illuminated the corners inside the cabinet.

When Zhou Ning checked the fourth bookcase, before he touched the partition, he saw two wooden strips on the edge of the wooden board behind. The edge of the board, where the strong flashlight shines, found a gap around the edge of the backboard.

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

"Don't worry, Zhu Xingxing will ask Lao Yang and the others to come over. Da Zhao will take fingerprints on this partition, as well as the wooden strips and the back panel, and collect samples, especially the wooden strips, which need to be sprayed with luminol reagent. There are black spots on the wooden strips." , I suspect it is blood."

Da Zhao came to his senses, dragged Zhou Ning to the side, and looked at the ground. Compared with the surrounding area, there were no footprints. The dust on the ground here is thinner, and the boundaries are clear, which are traces left by rubbing.

Da Zhao took a photo, and then he knelt directly on the survey board. The brush brushed over the partition, and two thumb marks appeared on the left and right. Obviously, this was the action of grabbing the partition. For the fingerprints of other fingers, Da Zhao lay directly on the ground.

There was no problem with the judgment, and fingerprints were left on the bottom, but to Da Zhao's disappointment, the fingerprints were those of latex gloves, and no fingerprints were left, but this discovery has already excited Da Zhao.

Holding the luminol, spray it carefully on the fingerprints. In the middle of the fingerprints, a dot-shaped fluorescent area appeared obviously. Da Zhao removed the partition.

Yang Xuetong and the others had already rushed over. Seeing Da Zhao's posture, Yang Xuetong quickly knelt and approached, and Sun Gaotie put the partition on the evidence bag on one side.

Da Zhao sprayed the luminol reagent on the small wooden strip. Sure enough, the two black spots that Zhou Ning pointed out were blood stains, and Da Zhao turned his head to look at Zhou Ning.

"I'm opening it!"

"Quickly stop the ink."

Before Zhou Ning could speak, Zhu Xingxing couldn't hold back, and shouted first.

Yang Xuetong held back his laughter. He and Da Zhao grabbed a small wooden bar and twisted it a little. With the removal of the wooden bar, the partition on the back bounced directly to the outside.

Da Zhao was quick and quickly caught the backboard. This action exposed the back. Yang Xuetong opened his mouth wide in surprise. Zhou Ning couldn't see it from the angle, so he was a little anxious.

"What's behind it? Is the wall hollow?"

Da Zhao handed the backboard to Zhu Xingxing, and then stepped aside to investigate the position of the backing board.

"There is an old-fashioned safe embedded in the wall. I don't know if it has been in disrepair for a long time. One side has collapsed. It is probably because of this that when I knocked on the other side, it made a hollow sound."

Quickly collected all kinds of information on the safe, found bloodstains and a few glove marks, looked at a pair of combination locks, and the keyhole. Yang Xuetong committed a crime.

"We can collect the fingerprints on the safe, but who can open this thing, and it's such an old style, I think it's too bad to just find someone who can open the lock?"

Da Zhao waved his hand and kicked Yang Xuetong's shoe with a look of indifference.

"Get up, I have a solution."

Yang Xuetong hurriedly stepped aside, Da Zhao stepped back half a step, and kicked towards the upper left corner of the safe. With this movement, the side that was originally tilted fell down with a click, and the safe tilted forward, Da Zhao grinned. .

"There's nothing that can't be done with a flying kick. If it doesn't work, then kick it again!"
