Serious Crime Unit 1

Chapter 400 Bone Cave (8)
The only drawback is that she has some petty bourgeoisie sentiments, which is not consistent with the profession of being a criminal police officer. Of course, she is a newcomer, and I believe that with time, she will become an excellent criminal police officer.

In the area of ​​polygraph detection, Wen Xiaorou has long been handy and can complete the work very well. After all, polygraph detection is not a very complicated technology. All you need to do is ask the suspect prepared questions. Today's testers are very sensitive and can detect the suspect's subtle heartbeat. , skin electricity, and pulse changes, the tester will alarm to prove whether the suspect is lying.

Wen Xiaorou first gave Yu Haihua a polygraph test. Yu Haihua was very anxious and was always in a very excited state, so it would not be accurate. For example, the polygraph test is inaccurate for people who drink alcohol and drug addicts. Wen Xiaorou kept comforting her and letting her relax slowly. After that, the polygraph test was officially started, and the results proved that Yu Haihua did not lie.

Then Lu Mingliang took a lie test. Lu Mingliang calmly accepted Wen Xiaorou's questions, but sometimes he was absent-minded, as if he was thinking about other issues. After the test, it was proved that he was not lying.

Maybe Lu Mingliang felt that he shouldn't be so emotional towards Wu Jiang and the others, and realized that confrontation was useless, so he and Yu Haihua left the city bureau silently.

The case hit a dead end and no one had any good ideas.

"When the case reaches a deadlock, what do we need to do most?" Wu Jiang asked.

"Reorganize the case and think deeply, maybe we can find new clues." Zhu Gang replied.

"No, the best way is to return to the scene. The scene is a gold sand mine. You can always find it if you go searching for it."

"The body and clothes of the deceased have rotted into mud, and even the wooden handle of the hatchet has rotted away. What else can be found at the scene?"

"The buttons on the clothes of the deceased will not rot, because the buttons are mostly made of materials such as resin, plastic, and metal. These things are not easy to rot. After scientific testing, it is said that these things will last at least 50 to 200 years if they are buried in the soil. It won’t be completely decomposed until years later, but we didn’t find the deceased’s buttons.”

"Even if the button is found, it doesn't mean anything, right? Because the source of the body has been found, finding the button of the deceased can only provide clues to find the source of the body. Can it have any other effect?"

"The discovery of the deceased's buttons is of little significance to the source of the body, but what if the murderer's buttons are found? That would be priceless." Wu Jiang said to Zhu Gang with a smile.

"Yes, why didn't I think of it? This is the best way at the moment. We take action immediately. We go to Beiwang Village to borrow a rice sieve from the villagers, lift half a meter of soil from the tomb hole to the ground, and sift carefully. Maybe We may find clues from it, and then sift through the floating soil within 5 meters around the entrance of the cave. The murderer may fight with Lin Yifeng above the entrance of the cave. What if the murderer's button is ripped off by Lin Yifeng and falls to the ground?"

"Yes, it is entirely possible, because Lin Yifeng has been working in the mountains for many years, can climb rocks and trees, and is very agile. If he had not been killed by the murderer, then Lin Yifeng might have resisted."

Zhu Gang called on all the members of the serious crime team. Feeling that this was not enough, he called on three other policemen, a total of 10 people, and drove three off-road vehicles towards Beiwang Village.

Zhu Gang called Xie Zengqiang in the car and asked him to help borrow 5 rice sifters and 5 dustpans. If they were used out, he would compensate them according to the price. It is enough to bring the rice sieve from the village cadre’s home.

After they arrived at Beiwang Village, Zhu Gang got off the car and went to the grocery store to buy three bundles of nylon ropes of different sizes. Xie Zengqiang brought the hatchet and rice sieve and put them in the trunk.Zhu Gang asked him to cooperate in sifting the soil because Xie Qiangqiang had experience.

After they arrived at their destination, they first put the loose soil from the bottom of the tomb hole into a dustpan, then lifted it up with a rope, sent it to a small flat 5 meters away, and sifted it with a rice sieve.

This is hard work, and everyone's clothes are soaked with sweat, but they don't complain about hardship. What they fear is not the hardship, but the life that may be sacrificed at any time, and the lack of support from the leader. Which criminal policeman said that he is not afraid of death? That is false, as long as everyone is afraid of death.

However, they will not hesitate to sacrifice themselves when defending the property and lives of the people.

On the day they enlisted in the army, they swore an oath under the national flag: I volunteer to become a People's Policeman of the People's Republic of China. I promise to be loyal to the Communist Party of China, to the motherland, to the people, to the law, to obey orders, to obey commands... not to be afraid of sacrifice, to serve the people wholeheartedly, I am willing to dedicate myself to the noble cause of people’s public security and work hard to realize my oath!
——This oath always rings in their ears.

Because the holes of the rice sieve are only as big as rice grains, and the rice sieve is very precise, only the rice can enter the sieve holes, and the millet cannot enter. Farmers use the rice sieve to filter out the rice that cannot remove the husk during rice milling. However, because The soil at the bottom of the cave is very wet, and most of it is sticky. They have to use their hands to crush the clay into grains of rice before it can pass through the sieve, so the workload is huge.The reason why Zhu Gang chose the rice sieve instead of the bean sieve was because he did not want to miss the physical evidence of the same size as the rice. Zhu Gang came from the countryside, and farmers had five or six kinds of sieves with different eyelet sizes in their homes, so he chose the eyelet sieve. The smallest rice sieve.

Because Wu Jiang was older, they were not allowed to sift rice. Shaking the sieve required a lot of strength. If he shook the sieve for a day, he would definitely get back pain. Therefore, Wu Jiang was responsible for pouring the soil and checking for clues. As a result, the soil at the bottom of the cave was sifted. Halfway through, Wu Jiang saw a copper buckle mixed in the soil, turning with the soil in Che Xiaolin's hand.

Wu Jiang asked Che Xiaolin to stop shaking and put the rice sieve on the ground. The two squatted down to check and saw a rusty copper buckle. Wu Jiang took out a pair of tweezers, clamped the copper buckle up and looked at it, and found a copper buckle. There are two words "Golden Pig" written in the middle, and there is a line of capital English around the two words "Golden Pig", which makes them particularly excited.

"Golden Pig" is a famous denim brand in China. It is very expensive and cannot be afforded by ordinary farmers. If this copper buckle was torn off the murderer by Lin Yifeng, then the murderer can be narrowed down to the local wealthy This is a very valuable clue.Wu Jiang told everyone to come on, they had found a copper buckle.

Xiao Ke and Lu Yingying also sifted out a small silver bracelet. Although there was no text on it, because it was relatively short, it could be judged that it was a silver bracelet for a minor, because adults generally do not wear silver bracelets, even if they can The wear is also relatively large.

There is a local custom: after a daughter gets married and gives birth to her first nephew or niece, the grandmother must give them silver necklaces, bracelets and other silverware. There is also a saying: "Wear silver when you are young, and gold when you are older." So, this is a silver bracelet given to my nephew by my grandmother.

Everyone analyzed that the silver bracelet might be of little value, because it was impossible for a child to kill the agile Lin Yifeng, and the gold pig and copper buckle were priceless and were most likely left behind by the murderer.

It wasn't until two o'clock in the afternoon that they finished sifting through all the half-meter-deep soil. In order to find more clues, Zhu Gang asked everyone to continue sifting the soil around the cave entrance. However, the soil within 5 meters from the cave entrance should be screened. It will take at least two days to finish screening everything.

Zhu Gang said that they must continue sifting, so they sifted the soil for two consecutive days, sifting all the soil within the designated area, but found nothing.However, the golden pig, copper buckle and small silver bracelet are already the biggest gains.

Golden Pig denim was more popular 10 years ago. It was a high-end denim produced by Pinsheng Clothing Company in Shishi City. It was one of the most famous brands in China at the time, with a series of products including clothes, trousers, shorts, skirts, dresses and so on.

At that time, chain stores were set up in every county with a population of more than 30. However, in recent years, for some reason, Golden Pig jeans have gradually faded out of the market and been replaced by brands such as Versace, Hugo Boss, and Yang Weis. Although the only franchise store in Yin County is still there, it no longer specializes in Golden Pig denim clothing, but sells denim clothing of various brands.

Zhu Gang, Wu Jiang and Che Xiaolin went to the Golden Pig Denim Clothing Store at No. 11 Main Street. When they walked outside, they saw that the store name had been changed to Golden Lion Denim Clothing Store. The original store of nearly 100 square meters had been divided into Two stores, each with an area of ​​50 square meters, and the other store sells children's clothing.It can be seen that the golden pig denim outfit has existed in name only.

There was a girl of about 17 years old and a young woman of nearly 30 years old in the store. When the girl saw them coming in, she immediately greeted them with a smile: "Welcome to the Golden Lion franchise store, please take a look..."

"We're not here to buy clothes. Is your boss here?" Zhu Gang asked in dialect.

"Here, she is our boss lady." The girl pointed at the young woman sitting at the counter surfing the Internet. The young woman was not playing any games and was so intoxicated that she didn't seem to notice their arrival.

Zhu Gang came to the counter and said to the proprietress: "Hello, we are from the county bureau's criminal police team. We want to know the situation from you. Could you please pause for a moment?"

"Oh, okay, tell me." She closed the game with the mouse and raised her head to look at Zhu Gang. The skin on her face was very white, as if she were European and American, with a kind of morbid beauty.

"Please help me see if this copper button is nailed to the Golden Pig jeans?" Zhu Gang took out an evidence bag containing the rusted copper button and handed the evidence bag to her.

The landlady looked at it carefully for a while and said: "This should be a genuine golden pig copper buckle. However, such a large copper buckle is no longer produced. The current copper buckle is smaller than this one, much more delicate, and the surface is very special." It's smooth, not so rough, it should be a product made a few years ago." Her voice was very soft, almost too soft to be heard, just like the distinguishing sound of a primary school student when being criticized by a teacher.
