"Look for the files and evidence of these cases."

Jiang Yuan picked out a few cases and asked Lei Xin to find something. He has done more cases now and has a different understanding of the cases.

The difficulty of a accumulated case is not only reflected in the nature of the case and the type of evidence, but also depends on the completeness of the evidence in the case and whether the evidence is collected sufficiently.

To put it bluntly, some backlog cases are broken by some idiots. But when faced with such backlog cases, you still have no way to do anything.

Jiang Yuan is still familiar with the criminal police team in Qianjin District. He is considered to be of the highest level in Qinghe City. However, it is still difficult for this level team to completely eliminate the existence of idiots. Jiang Yuan asked Lei Xin to sift it, and also hoped to find a case that was relatively low in difficulty, at least it seemed that it was relatively difficult.

As for taking the initiative to find difficult cases, it is to turn one's own special case team, the other party's criminal police team and even hundreds of people in the police station, and if it is influenced by political factors, it is force majeure. If it does not exist, it is pure stupidity.

Lei Xin took his men and went straight to the archives room and evidence room.

The Qianjin District Bureau's case has a large number of cases all year round, and their evidence room is naturally not as well organized as it is on TV. Of course, the hardware of the evidence room must be well organized, especially the large stainless steel cabinet at the front, which even looks a bit handsome.

However, the evidence in the cabinet is a bit messy. "One case, one cabinet" is a good system, provided that the increase in the number of cabinets can keep up with the increase of cases.

If you can't keep up, the cabinet is full, you can only find a way to stuff it too much.

Of course, the unfinished cases can still be treated with additional treatment. Despite this, various documents and documents are still filled with cabinets, which makes people distinguish them for a while.

Lei Xin was very serious in his division and did it himself wearing gloves.

The apprentice followed and whispered: "Lei Da, you can rest for a while. We will find out and call you to check."

"What are you going to have a rest at this time?" Lei Xin glared back and said, "We are not working hard for Jiang Yuan's case, we are working hard for our own case. Prepare the case well. If Jiang Yuan can solve it smoothly, he might be able to do more cases. He has come, so he won't leave if he does one case."

Lei Xin thought clearly that he had no other serial rape case to summon Jiang Yuan, so he had to use him as much as possible while Jiang Yuan was still there.

In the basement, Lei Xin and others were working in a humming manner, while Jiang Yuan and others in the conference room were chatting in groups of three or three.

Some people don’t like to talk, so they just hold a cell phone and watch it in the corner.

Jiang Yuan has not decided on a new case yet, but the criminal police officers from the special case team present are more active, boldly analyzing the cases at hand, and ask Jiang Yuan to make a judgment from time to time.

Li Jikuan felt itchy when he heard this. While a few people were talking, he suddenly said, "Captain Jiang, can you help me see a case?"

"It's okay if you just look at the evidence involved in the case." Jiang Yuan would usually help people in the group to see their fingerprints and footprints, but he definitely didn't have time to handle cases one-stop like in Qinghe City or Beijing.

Li Jikuan naturally didn't expect this and said hurriedly: "It would be great if you can see the evidence. Our task force took a case five days ago and has been busy until today without any results. The ones we came to arrest this time are also related personnel involved."

"Do you have any footprints, fingerprints or blood?" Jiang Yuan didn't even ask about any case, so he asked about the part of the evidence first.

Li Jikuan nodded quickly and said, "There are footprints, DNA, and blood."

As Li Jikuan said that, he quickly entered the intranet from the computer and showed it to Jiang Yuan, and introduced it: "We analyzed this case as a case of seeking revenge or passionate murder. The victim was a small contractor who undertook the renovation of a residential house in the community. He was carrying an angle grinder and other machinery that day, but he was hit by three knifes and died of excessive blood loss..."

While he was speaking, Jiang Yuan also saw photos of the scene involved.

The incident happened in a stairwell in a residential building that was being renovated. The deceased fell on the stairs between the second and third floors, with a large pool of blood formed on his feet and under his head.

The victim was hit in the abdomen with three consecutive stabs, and there were signs of struggle. He should have crawled forward two steps. An angle grinder and a tool box fell beside him, and his clothes were relatively clean, which means that he had either not started working or had just started working for a while.

Because it is a community that is being renovated, there is no camera inside the community, but there is a camera working at the entrance of the community. However, the access control of the community is not strict, and there is basically no restriction on entry and exit. During the renovation, it is still a mode of mixed traffic between people and vehicles, and its camera cannot capture all the faces in the car.

The surroundings of the community are similar. There are either farmland or large construction sites nearby. There is a village nearby, but it is also a distance of several hundred meters, and there is no monitoring.

Liu Jinghui was also curious, listened to him from the side, and stood behind to see Jiang Yuan looking through the photos of the crime scene, and couldn't help but say, "Fortunately it wasn't robbery or murder, otherwise, it would be a matter of life to solve this case."

Li Jikuan smiled bitterly: "Now we rely on our lives. We checked the victim's relationship network, but we didn't find the suspect. What did the victim say? His job is to decorate, and he has some disputes with his family and workers, but it has not reached the level of murder."

He was not so pessimistic before he left the house. At that time, the case was a fresh and hot murder case. The police in the task force were also full of confidence. However, for two days after Li Jikuan went out, the case had already moved from 3 days of gold to 5 days of silver.

There is no suitable suspect at this time, it is really a very dangerous signal.

Jiang Yuan understood Li Jikuan very much, and he had seen him for a long time.

Nowadays, murder cases are usually relatively ordinary. The main force of killing people is already agile. The 1950s and 1960s have gradually transitioned to the 1970s and 1970s and then later. The main focus of this generation of young people is that they have many ideas, it is difficult to implement, and their emotions are particularly uncontrollable.

Just like Jiang Yuan did the case of an internet celebrity in Malaysia, the murderer who was only 15 years old, although he was a courier who needed physical strength, his body was not strong, and he was even a little unable to compete with a young internet celebrity who was in his early 20s who often exercised. But he had a very bad temper. He wanted to rob him if he couldn't borrow money, but he wanted to find a knife if he couldn't grab it...

Not only that, the 15-year-old boy who rarely does housework also wants to wipe a lot of blood clean - if he can do this easily, he might fantasize about dismembering or abandoning the corpse.

In fact, many assaulters have had similar fantasies. If they fail to execute, most of them will be defeated by reality.

If a normal person is poked into an artery or an important blood organ, he can flow out more than 3,000 milliliters of blood, and the most can be four or five thousand milliliters. Moreover, dead people may be incontinent, so it is possible that hundreds of milliliters of urine can be mixed into it. How difficult is it to try to clean the blood? A 25-liter bottle of Coke, pour four bottles on the ground and try to see if it can be wiped clean.

If a person with a little experience in housework plans to kill and dismember himself, he cannot use such a killing method. At least, he has to move the person to the bathtub before slapping his neck. This is like slaughtering a pig in a basin. If you don’t do this, the whole family will use it to wash the yard from the Chinese New Year to the third day of the New Year.

The murder case at this renovation site in Jeju is not complicated, but after several days of verification, there was no result, which makes people anxious.

Li Jikuan just arrived at the stage of asking for help, but he was not yet actively seeking help.

The Jeju police will not be really anxious until the case cannot be solved in a week.

If such a case that is devoted to all employees cannot be solved in a week, the probability of becoming a accumulated case is very high.

Jiang Yuan had no intention of taking over their case, but just helped me. After looking at the bloody stains at the crime scene, the bloody footprints left on the scene, he said, "It's good that way, I'll give you a range, and I'll find someone to compare and see if I can meet it."

"Okay." Li Jikuan didn't realize what Jiang Yuan was going to do.

Wang Chuanxing next to him had already taken out his notebook, tried the pen, and placed it in front of him.

"The murderer is 1.75 meters tall, a man, with a well-proportioned figure and strong body, weighing 140 kilograms, and his right leg is slightly longer than his left leg. This can be seen clearly from his footprints, about two centimeters long, so he is lame. In addition, do you have any judgment on the left hand and the murder weapon used to kill people?"

Jiang Yuan said it was slower, but Li Jikuan's mind was slower.

At this time, Li Jikuan had only one thought in his mind: the lame left-handed man, isn’t this just asking someone, the case has been solved?

When Li Jikuan thought about it for a while, he realized it and said, "It's a single-edged one, about 30 cm in length, pointed, and small handguards. It's suspected to be a bone-clearing knife."

The murderer stabbed three times, and the traces of the weapon left were quite heavy. The forensic doctor can make corresponding analysis of the morphological characteristics of the weapon based on the wound of the deceased.

Jiang Yuan nodded and said, "The previous part of your forensic doctor is correct. As for the specific knife, I prefer ethnic knives, such as hidden knives."

Jiang Yuan casually searched a picture of a hidden knife from his mobile phone for Li Jikuan to see, and said, "I don't know if the tool management in your city is strict. If you want to bring such a knife, you can't pass the security check, so you can't take a plane or a train. Therefore, it's not easy for ordinary people to carry it with you, especially those who are sharp."

"So it may be people from ethnic minorities?" Li Jikuan's mind finally turned around: "They may have some ethnic habits that they use knives, or they like to bring a knife on their bodies..."

Jiang Yuan nodded and said, "It's possible, but it's not sure. I'll find it back and verify it."

Li Jikuan nodded repeatedly, picked up his cell phone, looked at Wang Chuanxing, and whispered: "Captain Wang, please borrow one of the notes for us. I'm afraid I'll say something wrong..."

Wang Chuanxing turned the notes openly.

Li Jikuan hurriedly took photos, laughed twice, turned around and ran away, feeling like he had obtained some secret.

"Old Li runs so fast?"

When Lei Xin came in outside, he saw Li Jikuan pounding his legs quickly.

"Jiang Yuan had just described him as a murderer." Liu Jinghui also felt a little itchy and asked, "How is your case investigation? Are there all the evidence?"

"Uh, all...all..." Lei Xin nodded and frowned, still thinking, what does it mean to describe a murderer?
