Chapter 27: Stranger Case

"Are you really going back to rest?" Wang Zhong looked at Jiang Yuan, who was packing his things, feeling very clearly heartbroken. He occasionally arrived late and left early, but he had never been asked by a leader to arrive late and leave early. And he was envious.

Jiang Yuan rubbed his shoulders and said righteously: "Staying here is nothing to do. The folding bed is too hard to sleep on, I'm going back to make up for sleep."

Wang Zhong was envious to the point that his nose and neck were about to break. Who didn't know that the folding bed was hard to sleep on, who didn't know that working overtime and staying up late would ruin the body and shorten life...

Wang Zhong sighed: "Team Leader Huang wants to give you a dormitory, you don't want it, the dormitory is very hard to ask for..."

Wu Jun interrupted Wang Zhong: "Jiang Yuan climbed up and down for a day yesterday, that was really tired. The case is solved anyway, the link of handling the case, Jiang Yuan still has to learn, don't worry."

The case is solved, the criminal suspect has been caught, and the next step is the handling link that criminal police hate deeply.

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

Wu Jun actually doesn't like the process of handling the case either. The meat part of his forensic work is nothing more than scene investigation, autopsy, and a lot of toxicology analysis, etc. The total working time adds up to 20 hours, which is enough. This time it was done smoothly, and there is not much work left.

A few days ago, Wu Jun naturally wanted to hand over most of these works to Jiang Yuan. The purpose of recruiting newcomers is not just for this.

But now, looking at the rarity of Jiang Yuan by the Criminal Investigation Brigade Captain, and looking at Jiang Yuan taking the initiative to re-examine and achieving huge results, Wu Jun also felt that there was no need to use the livestock work method on Jiang Yuan.

Letting Jiang Yuan rest a little, and then using it later, can also be considered as following Team Leader Huang's order, which belongs to sustainable development.

Wang Zhong really wanted to emphasize that he also climbed up and down for a day yesterday, and was also exhausted—although he didn't make any actual achievements, that was a matter of ability, not a lack of effort...

Watching Jiang Yuan pack up quickly and go out directly, Wang Zhong could only shout from behind: "Wait until the interrogation results come out, I'll tell you."

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

The time spent on interrogation was much longer than Jiang Yuan expected.

By the afternoon of the next day, when it was time to get off work again, there was a case report.

In front of Jiang Yuan, the system's task completion prompt jumped out immediately:

Task Completed: Start from the Beginning

Task Content: Re-examine the Xue Ming case scene to obtain leads and evidence.

Reward Content: Skill expansion once.

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

1. Chongqing-style single-fingerprint analysis method—arch-type fingerprint identification (LV3)

2. Egg fried rice production (LV3)

3. Crime scene investigation (LV4)

4. Camping (LV2)

Jiang Yuan's gaze stayed on the third item for a long time, but he still chose the first item, Chongqing-style single-fingerprint analysis method—arch-type fingerprint identification (LV3).

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

The missing arch-type fingerprint note meant that all types of fingerprints were covered by Jiang Yuan's skills.

Jiang Yuan felt relaxed unconsciously.

Knowing only the identification of arch-type fingerprints naturally had many inconveniences in actual operation, which was why he didn't expand Crime Scene Investigation (LV4).

From his own feeling, LV4 Crime Scene Investigation was obviously stronger than LV3 skills, at least compared to his colleagues in the Criminal Science Squadron, LV4 was clearly beyond the level of his colleagues, and its upper limit might be something that ordinary technicians couldn't reach even if they tried their best.

Jiang Yuan being able to confidently do re-examination also had such a foundation.

Compared to this, the amplitude of exceeding LV3 skills was not so exaggerated. It was about equivalent to the peak state reached by a technician purely based on experience. And in this state, Jiang Yuan felt that comparing fingerprints was not easy. For example, facing the previous "Highway Service Area Gang Oil Theft Case," he gave up comparing two sets of fingerprints one after another.

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

However, the characteristic of being able to solve cases directly through fingerprint identification attracted Jiang Yuan more.

On the other hand, crime scene investigation is more time-consuming and tends to be current cases. From the high perspective of maintaining social stability and highlighting social justice, I feel that I can wait a little longer—as a system owner, Jiang Yuan feels that his perspective should be higher.

Knock, knock.

Wang Zhong knocked on the door and rubbed in, opening his mouth and saying: "Have you heard?"

"You say." Wu Jun was in a state of waiting.

"Hehe." Wang Zhong smiled and said: "The murder weapon was salvaged, it's an iron case."

"Really salvaged?" Jiang Yuan was surprised. Many of his family's houses could see the Tai River. Although the flow rate of the river was not fast, with such a wide river surface and several days of time, being able to salvage the murder weapon was indeed beyond his expectation.

Wang Zhong curled his lips and said: "Frogmen and divers invited from other places, etc., took people there today, while identifying the scene of throwing the murder weapon, while searching on the spot, and found it until now. The money spent is more expensive than the car bought by Team Leader Huang."

Team Leader Huang himself drives a Pajero eliminated by the unit.

Jiang Yuan clicked his tongue. This was only a part of a case, and he was willing to spend so much money. It is conceivable how much the case-handling cost would be for a homicide case.

With Ningtai County's family background, if a few more homicide cases like this come, the police station will have to go into debt.

"The murder weapon was found, is the criminal suspect completely admitting guilt?" Jiang Yuan asked again: "I thought the criminal suspect's psychological quality was extremely poor, and I thought the case was handled on the same day."

"That's you thinking too much." Wu Jun said: "This is a homicide case, it is very likely to be sentenced to death, every move must comply with specifications. For example, the criminal must be sent to the detention center, the interrogation time must comply with regulations, cannot be overtime, cannot be interrogated at night, cannot threaten..."

"So, this time it was quite fast." Jiang Yuan understood a little.

"That's it, it wasn't a professional criminal in the first place." Wu Jun said while clicking his chopsticks, "Let's put it this way, I have seen many homicide cases, the more premeditated the crime, the more fully prepared the criminal, the faster they confess when they enter the interrogation room. Because they do so much preparation, they are afraid of being caught."

"Seems quite reasonable." Jiang Yuan followed Wu Jun's train of thought, nodded unconsciously, and then asked Wang Zhong: "What is the motive of the murderer?"

"This is interesting." Wang Zhong had been waiting, and he enjoyed himself for two seconds before saying seriously: "The murderer is a licking dog of the victim's mistress."

Wu Jun, who was over fifty, knew what a licking dog was, but couldn't help but be surprised: "There are licking dogs for prostitution?"

"Unexpected, right." Wang Zhong ate two mouthfuls of rice, swallowed, and then said: "The suspect has been persuading the prostitute to go ashore and be good, but was perfunctory, and was also cheated of red envelopes. He found the victim because the victim helped introduce business, including the afternoon of the day, the prostitute went to the provincial capital to deliver takeout, which was introduced by the victim."

"He himself is 500 once, introduced people to go, 2000 once? He took a cut?" Wu Jun asked.

Wang Zhong nodded: "Just took that 500."

Wu Jun laughed: "White prostitution."

"Yeah." Wang Zhong shook his head, then said: "The suspect also knew about this, found the door, claimed to want to persuade the other party not to do this anymore, but as a result, there was a verbal conflict. It is said that the victim spoke very badly, he was excited for a while, and took out a knife, and one knife was fatal, is it outrageous?"

"What's more outrageous is that it was the first time he killed someone, and he still took a bath at the crime scene? What was he thinking?"

"Just wanted to wipe the evidence clean. This person is still a regular college graduate. After graduation, he studied for postgraduate entrance exams, asked for money from his parents, and sent red envelopes to the prostitute. He claimed not to know the victim, just wanted to clean up the evidence, and after going out, he hid here and there, hoping to escape punishment."

Wu Jun had heard more outrageous stories, but at this time, he couldn't help but shake his head, but from another angle: "Don't say, today's case, it really is a stranger case."

Wang Zhong coughed twice and said in a low voice: "Team Leader Huang judged before, it was a crime committed by an acquaintance..."

"The one who pointed it out was you." Wu Jun glanced at Wang Zhong.

Wang Zhong smiled bitterly.

"Speaking of which, this case, if Little Jiang hadn't gone to re-examine, it would be hard to say." Wu Jun's tone was quite meaningful.

Wang Zhong was stunned and immediately followed: "Indeed, stranger case, without peeling three layers of skin, it is very difficult to solve."

The murderer and the victim have no direct connection, and even have no intersection, which can be counted as a stranger case. In short, the murderer is not in the victim's relationship network.

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

And as long as you leave the relationship network, whether it is for money or for a moment of anger, the difficulty of solving the case will rise by more than one layer. The serial murder cases that become famous cases are essentially the same. If there are no witnesses or direct evidence, whether it is solving or convicting, they face great difficulties.

And for the Ningtai County Criminal Investigation Team, any case with the word "stranger" makes them have a headache, let alone a homicide case.

"Little Jiang has something." Wu Jun was quite emotional, suddenly feeling that the life he dreamed of not moving corpses seemed to be approaching, and seemed to be moving away. ===== CHAPTER 28 =====
