Chapter 27: Stranger Case

"Are you really going back to rest?" Wang Zhong looked at Jiang Yuan who was packing up, and he was clearly upset. He would occasionally be late and leave early, but he had never been asked by his superiors to be late and leave early. And he was envious.

Jiang Yuan rubbed his shoulders and said confidently: "It's okay to stay. The camp bed is too hard to sleep, I want to go back to catch up on my sleep."

Wang Zhong's nose and ankles were about to break with envy. Everyone knows that camp beds are hard to sleep on, and everyone knows that working overtime and staying up late will damage your body and shorten your life...

Wang Zhong said sadly: "Captain Huang wants to give you a dormitory, but you don't want it. Dormitories are very difficult to get..."

Wu Jun interrupted Wang Zhong and said: "Jiang Yuan climbed up and down all day yesterday, and he was really tired. Anyway, the case has been solved. Jiang Yuan still has a lot to learn about the handling of the case, so don't worry."

The case has been solved, and the suspect has been arrested. Then the next step is the handling of the case that criminal police hate.

Handling a case is very energy-consuming. If solving a case is regarded as eating, handling a case is equivalent to cooking, washing dishes and cleaning the table.

Wu Jun actually doesn't like the process of handling a case. The most important part of his forensic work is nothing more than on-site investigation, autopsy, plus a toxicological analysis, etc. The total working time is enough for 20 hours. This time it went smoothly, and there is not much work left.

A few days ago, Wu Jun would naturally hand over most of these tasks to Jiang Yuan. Isn't this the purpose of recruiting new people?

But now, seeing the captain of the criminal police team's rare look at Jiang Yuan, seeing that Jiang Yuan took the initiative to re-investigate and achieved great results, Wu Jun also felt that there was no need to use the animal work method on Jiang Yuan.

Let Jiang Yuan take a break and use him again, which is also in accordance with Huang Qiangmin's order, which belongs to sustainable development.

Wang Zhong wanted to emphasize that he had also been climbing up and down for a whole day yesterday and was also exhausted - although he did not make any actual achievements, it was a problem of ability, not a lack of effort...

Watching Jiang Yuan quickly pack up his things and go out directly. Wang Zhong could only shout from behind: "I'll tell you when the interrogation results are out."

"Okay." Jiang Yuan waved his hand and disappeared from the stairs.

The interrogation took much longer than Jiang Yuan expected.

It was not until the afternoon of the next day, when it was time to get off work, that the case report was released.

In front of Jiang Yuan, the prompt of task completion immediately popped up:

Task completed: Start from the beginning

Task content: Repeat the investigation of the Xue Ming case scene to obtain clues and evidence.

Reward content: Skill expansion once.

Then, three skill options appeared in front of Jiang Yuan.

1. Chongqing-style single-finger fingerprint analysis method - bow pattern identification (LV3)

2. Egg fried rice making (LV3)

3. Crime scene investigation (LV4)

4. Camping (LV2)

Jiang Yuan's eyes stayed on the third item for a long time, and he chose the first item, Chongqing-style single-finger fingerprint analysis method - bow pattern identification (LV3).

In an instant, the skill became Chongqing-style single-finger fingerprint analysis method (LV3).

The absence of the noted bow pattern means that all types of fingerprints are covered by Jiang Yuan's skills.

Jiang Yuan felt relieved unconsciously.

Only knowing the identification of bow patterns is naturally inconvenient in actual operation, which is why he did not expand the crime scene investigation (LV4).

As far as he feels, the crime scene investigation of LV4 is obviously stronger than the skill of LV3. At least compared with his colleagues in the criminal department squadron, LV4 is obviously higher than their level. It may be that ordinary technicians may not be able to reach it even if they try their best.

Jiang Yuan can confidently do the re-investigation, which is also based on this foundation.

In contrast, the degree of surpassing the skill of LV3 is not so exaggerated. It is roughly equivalent to the peak state reached by a technician purely based on experience. In this state, Jiang Yuan felt that it was not easy to match fingerprints. For example, when facing the previous "highway service area gang stealing oil case", he gave up the comparison of two sets of fingerprints in succession.

Of course, according to the skill level, expanding "Crime Scene Investigation (LV4)" may be a more cost-effective choice. Upgrading to LV5 may bring about a qualitative improvement.

However, the feature of being able to solve the case directly through fingerprint identification is more attractive to Jiang Yuan.

On the other hand, crime scene investigation is more time-consuming and more inclined to current cases. From the perspective of maintaining social stability and demonstrating social justice, it feels like we can wait a little longer - as the owner of the system, Jiang Yuan feels that his perspective should be raised a little higher.

Dongdong.

Wang Zhong knocked on the door, came in, and said, "Have you heard?"

"You say." Wu Jun looked like he had been waiting for a long time.

"Hehe." Wang Zhong smiled and said, "The murder weapon has been recovered, and the case is ironclad."

"Really recovered?" Jiang Yuan was surprised. Many of his houses can see the Taihe River. Although the flow of the river is not fast, it is such a wide river, and there are still several days to recover the murder weapon. It is indeed beyond his expectation.

Wang Zhong curled his lips and said, "The frogmen and divers invited from other places took people there today, while identifying the scene where the murder weapon was thrown, while searching on the spot, and found it now. The money spent is more expensive than the car bought by Captain Huang."

Huang Qiangmin himself drives a Pajero that was discarded by the unit.

Jiang Yuan clicked his tongue twice. This is only part of a case. If he is willing to spend so much money, he can only imagine how much it will cost to solve a murder case.

As far as Ningtai County's family is concerned, if there are a few more murders like this, the police station will be starved.

"The murder weapon has been found. Has the suspect fully confessed his crime?" Jiang Yuan asked again: "I said before that the suspect's psychological quality was extremely poor. I thought the case was completed that day."

"That's because you are overthinking." Wu Jun said: "This is a murder case, and it is very likely that the death penalty will be imposed. Every action must comply with the regulations. For example, if a prisoner is sent to a detention center, the interrogation time must comply with the regulations. It cannot exceed the time limit. Interrogation at night, no threats..."

"So, it went pretty fast this time." Jiang Yuan understood somewhat.

"That's it. He is not a professional criminal in the first place." Wu Jun nodded his chopsticks and said, "Let's put it this way, I have been exposed to a lot of murder cases. The more premeditated the crime, the more prepared the criminal will be. In the interrogation room, the sooner they confess, because they are afraid of being caught.”

"It seems quite reasonable." Jiang Yuan nodded unconsciously, following Wu Jun's train of thought, and then asked Wang Zhong: "What was the murderer's motive?"

"This is interesting." Wang Zhong had been waiting for a long time. He was enjoying himself for two seconds before he said seriously: "The murderer is the victim's mistress."

Wu Jun, who is over 50 years old, knows what licking a dog is, but he still couldn't help but asked in surprise: "Selling sex and licking a dog?"

"I can't believe it." Wang Zhong took two mouthfuls of rice, swallowed it, and then said: "The suspect has been trying to persuade prostitutes to go ashore and become good friends, but they have been perfunctory and defrauded of red envelopes. He approached the victim because he was victimized. People helped introduce businesses, including a prostitute who went to the provincial capital to deliver food that afternoon, who was introduced by the victim. "

"He pays 500 for himself and introduces people to him. 2000 for him? Did he take a tap?" Wu Jun asked.

Wang Zhong nodded: "Just draw the 500."

Wu Jun was delighted: "It's free."

"Yes." Wang Zhong shook his head and continued: "The suspect also knew about this and came to the door, claiming that he wanted to persuade the other party to stop doing this. As a result, there was a verbal conflict. It is said that the victim's words were unpleasant. He In a moment of excitement, he took out the knife and killed him with one blow, isn't that outrageous? "

"What's even more outrageous is that he committed a murder for the first time and took a shower at the crime scene? What did he think?"

"I just want to erase the evidence. This man is a serious college graduate. After graduation, he took the postgraduate entrance examination at home. After asking for money from his parents, he gave red envelopes to prostitutes. He claimed that he did not know the victim, so he I want to get rid of the evidence and hide from XZ after I go out, hoping to escape punishment."

Wu Jun had heard even more outrageous stories, but at this moment he couldn't help but shake his head, but said from another angle: "Don't tell me, today's case was really committed by a stranger."

Wang Zhong coughed twice and whispered quickly: "Captain Huang previously judged that an acquaintance committed the crime..."

"You are the one who asked the question." Wu Jun glanced at Wang Zhong.

Wang Zhong smiled bitterly.

"After all, if Xiao Jiang hadn't gone to re-investigate this case, we wouldn't be sure." Wu Jun's tone was profound.

Wang Zhong was stunned and immediately followed: "It is true that strangers commit crimes and it is difficult to break them without taking off the third layer of skin."

If there is no direct contact or even intersection between the murderer and the victim, it can be considered a crime committed by a stranger. In short, the murderer is not in the victim's network.

The so-called grievances and hatreds are all based on interpersonal relationships. The cases that are easiest for the police to solve are usually solved along the network of relationships.

And as long as you are out of the network of relationships, whether it is for money, temporary anger, etc., the difficulty of detecting the case will increase by more than one level. The reason why serial murder cases that often become famous cases is so troublesome is essentially the same. If there are no witnesses or direct evidence, it will be extremely difficult to detect or convict.

For the Ningtai County Criminal Police Team, any case with the word "stranger" on it is a huge headache, let alone a murder case.

"Xiao Jiang has something." Wu Jun sighed with emotion, suddenly feeling that the life he dreamed of no longer moving corpses seemed to be getting closer, and then it seemed to be further away.
