The police officers wearing brand-new uniforms passed by the gate of Jiangcun Community, attracting passers-by to look at them. Some people picked up their mobile phones to take pictures of Wu Junhao, with his chest raised and his head raised, looking straight ahead. His No. 1 Squadron has not yet been reorganized into the Patrol Anti-Explosion Brigade, but he has been planning the walking patrol for several years. Now that he has the opportunity, Wu Junhao can't wait to use it.

Foot patrol has a great impact on ordinary criminal crimes and can greatly improve the level of public security. The Hong Kong Police Department already has considerable experience in this regard. The Japanese police department also has a lot of experience. Countries such as the United States and the United Kingdom use more police car patrols due to different living conditions.

If we want to talk about the disadvantages of foot patrol, the first disadvantage is that it is tiring, so that it is used everywhere to exploit young people.

Let newly recruited police officers work as patrol officers. Those who are unwilling to do so will either be fired or cancel their promotion and let yourself leave. In this way, the sunk costs can be kept as low as possible.

The second point is the consumption of a lot of funds. Foot patrols are a pure expense and pose a certain risk to police officers, which means relatively high salaries must be given to young police officers. Police work does not produce direct value. Improved public security will not reduce the cost of criminal cases.

All in all, having police officers patrolling the city is very useful and meaningful.

If you want to ask why Ningtai County or domestic cities did not implement this strategy in the past, the bottom line is that there is a lack of people and money.

In a few years, when some cities emerge from the financial quagmire, foot patrols will definitely be arranged. Just like Ningtai County.

In fact, if a local police station really wants to improve through business, learning from the Hong Kong police has always been a shortcut.

Wu Junhao felt more and more comfortable as he walked, feeling like he was getting paid to exercise.

He actually doesn't like trivial criminal police cases. Especially in recent years, the requirements for handling cases have become higher and higher. All kinds of paperwork are complicated, and investigations have to be supplemented at every turn, but all the work must be expressed on paper in the end. This Wu Junhao felt very unhappy.

Of course, if it's not fun, it's not fun. Most of the work is not pleasant. If anything, Wu Junhao is still motivated, otherwise why would he spend so much energy training.

What he didn't expect was that the opportunity came so suddenly and happily.

Wu Junhao held his head high. From today on, he is also a full-time deputy subject!

Jiang Yuan stayed at home for another two days, and after a little repair, Wang Chuanxing and Tang Jia sent over the recently reviewed cases.

Nowadays, people from all over the country have invited Jiang Yuan and Jiang Yuan to work on the backlog of cases. With so many cases, it is a waste of time for Jiang Yuan to look at them by himself. Especially some major cases involve all aspects and must be looked at very carefully.

Wang Chuanxing and Tang Jia were responsible for the primary election work.

Jiang Yuan deliberately chose lunch time and came to the canteen of the Criminal Police Brigade with a large basket of meat.

The Jiang family really can't finish the meat. Jiang Fuzhen's hobby is roasting and cooking meat. He hopes that the stove at home can keep cooking.

Now that the conditions of the people in Jiangcun have improved, no one is short of a bite of meat. Therefore, Jiangfu Town often spends a lot of money on banquets, or cooks the meat and gives it away in order to consume it.

As for opening a store, Jiang Fuzhen did not consider it. He was not willing to work hard to renovate the store, and he was even more worried that the store would be demolished after it was completed.

This kind of thing has not happened before.

The police officers of the Criminal Police Brigade are naturally not picky. Seeing the trembling meat coming from Jiang Yuan, they can't help but tremble in their hearts. They are all busy spreading salt and making sauce. Very happy.

Jiang Yuan also cut a large piece for himself, and made a bowl of Yangchun noodles. He cut up the large pieces of meat and threw them into the soup. He added a spoonful of beef soup that he brought over, and it felt like he was home. Same.

"Tell me about it." Jiang Yuan took two sips of soup, then ate a piece of meat and noodles with chopsticks, and raised his head comfortably.

"The first case we screened out was the dismemberment case." Wang Chuanxing looked at Jiang Yuan's expression and continued: "The case occurred 20 days ago. It was discovered by the Changyang Municipal Bureau beside the grass in the Shishan section of Taihe River. Part of the body. Suspected second scene."

"Oh, it was moved?" Jiang Yuan was indeed interested, took a bite of meat, and said, "Tell me more about it."

"Yes." Wang Chuanxing found out that the first case aroused Jiang Yuan's interest, and he was very excited and said: "The total weight of the household block is about 40 kilograms. Two days before the discovery, there happened to be heavy rain in the local area and the tide in the Taihe River was high. Therefore, there was initial suspicion. The river washed away some of the body parts, but there was no success in retrieving them."

At this time, Tang Jia had opened the internal page related to the case, put it on the PAD, showed it to Jiang Yuan, and said: "The head was not found in the household block, and there was no key information such as fingerprints. The Changyang Municipal Bureau extracted DNA, and there was no "Compared."

"That is to say, the source of the corpse has not been confirmed?" Jiang Yuan nodded without surprise. If it was confirmed, he probably would not have found it. "Yes, the corpse was highly corrupted and was found in the grass. , basically no clothes, plus heavy rain——" Tang Jia frowned as he spoke: "This case should be very difficult. Do we want to pick it up? "

"You have to believe in the intelligence of the criminal suspect. A criminal suspect who abandoned his body in the grass by the river would not be very professional." Jiang Yuan said something from a distance, and then smiled and said: "Please help me look through the pictures."

As Jiang Yuan spoke, he lowered his head to take a big bite of noodles, then raised his head to see Tang Jia flipping through page after page of pictures of the scene.

The scene can be described as a mess. Of course, most of the scenes are like this. It is impossible for a single person to handle a 100-pound beast in an elegant way. It can only be a mess.

The more unique part is that there are only some head-sized or two head-sized body parts at the scene, which shows that the murderer's physical strength is still very good and the cutting is also very detailed.

If we briefly connect it with the previous case, it is guessed that the probability of there being two murderers in this case is very low. If there are two murderers, it is not necessary to cut the body into such small pieces, because it is relatively easy for two people to carry the body. On the contrary, if the body is cut into such small pieces, it will be greasy and sticky, and there will be no place to hold it.

Even if the body is as big as two heads, it actually needs two hands to hold it. Imagine buying such a big piece of meat at home, it will hurt your hands to throw it into the bag.

Jiang Yuan ate noodles while watching. He ate all the noodles with a few chopsticks, picked up the meat and asked, "Are there any murder weapons or packaging materials?"

"No murder weapons. Some cloth strips and fiber bags were found at the scene. They were stained with blood. They were initially determined to be packaging materials." Wang Chuanxing also had a PAD in his hand. He immediately turned to the corresponding photos and showed them to Jiang Yuan.

The first picture was a long-range photo of the place where the body parts were located. Five green and blue fiber bags were half submerged in muddy water.

Wang Chuanxing said, "The rising tide took away some body parts, but the scattered fiber bags were filled with mud and sand, and they were silted up on the side. "

"The previous dealer has been checked. What do you say? "

"They are all relatively common woven bags. They are widely used in the market. There is no conclusion for the time being. "

"Trace traces are found in the bags. Take more. DNA is also collected from each body part to ensure that it belongs to the same person. "Jiang Yuan slurped and began to drink the soup.

The experience he gained from the case at Changle City Police Station was that high-tech equipment should be used as much as possible. He is no longer the little Karami when he first arrived in Ningtai County, and Huang Qiangmin's asking price is no longer something that can be offset by a used car.

Therefore, the cases he is facing now and the police stations in the jurisdiction of the cases do not care about the testing fees of several hundred yuan each time.

Of course, on the surface, they still care, but in their hearts, everyone has been able to agree with this kind of wasteful expenditure. Compared with solving the case, compared with the case led by Jiang Yuan, this kind of testing expenses is really nothing.

It's like a patient who has finally passed through the body. The powerful person next to him contacted the medical team of a certain expert and was admitted to the hospital for treatment. Although he hoped that the cost of treatment would be lower, he would never raise any objection to the special inspection project opened by the medical team, nor should he raise any objection.

Jiang Yuan also consciously put this inspection in advance. Trace evidence is time-consuming, so there is no need to wait until he arrives to do it.

As for this case, there are a lot of body parts as big as watermelons, and there is no DNA in the body. There are very few things that can be used, and trace evidence is almost necessary.

Tu Chuanxing also agreed without surprise, and said while recording: "I will communicate with them and take more trace evidence points. But in this case, the woven bag will probably be cut up."

"Take more photos of the places with logos, and cut them if they are cut." Jiang Yuan just nodded. Physical evidence is also damaged. To some extent, the inspection of physical evidence is also a loss of physical evidence, but this is a two-sided thing. It is impossible to have both. Even Jiang Yuan can only accept it.
