I'm not a genius detective

Chapter 105 Daibin's Infidelity
When Han Ling arrived at the urban village, it was already past six o'clock, and there was still about an hour before dark.

Darkness can bring many difficulties to criminal investigations, such as hindering crime scene investigation, increasing the difficulty of securing evidence, and reducing the efficiency of environmental observation and interviews.

Within an hour, we need to gather as many clues as possible.

Han Ling truly hadn't expected Dai Bin to die.

He had already learned about the case in detail. Judging from the victim Xiao Yuxuan's personality, it could be summed up in two words: courting death.

He wouldn't be surprised at all if a woman with this kind of personality was stabbed; it was either her husband or another man outside the marriage who did it.

Now that her husband Dai Bin is dead, the verdict on Xiao Yuxuan's intentional injury case must change.

The killer's target may be this couple.

Tong Feng saw Han Ling and quickly walked over to her, explaining the details of the incident.

"I heard from Director Jiang that it is suspected to be arsenic poisoning."

"Arsenic?" Han Ling received the new information, and his judgment of the case changed again. "I thought he was stabbed to death."

Tong Feng: "I also thought it was a stabbing to death, which would put me in the same position as Xiao Yuxuan. Generally speaking, suspects shouldn't easily change their modus operandi, right?"

Police academies have taught relevant courses, and the suspects have fixed habits and behavioral dependencies. Unless there are special circumstances, once they have chosen a method of committing a crime, they will not change it midway.

Theft, fraud, intentional injury, and serial murders are all examples of this.

Deliberately changing your methods will only increase the risk of exposure, unless you are confident that you have upgraded your techniques.

“Hmm.” Han Ling agreed with Tong Feng’s words. “There are three possibilities. The first possibility is that the suspect was venting his anger on Xiao Yuxuan and was willing to kill her, while he was willing to kill Dai Bin. The second possibility is that there are two suspects. The third possibility is that Dai Bin committed suicide.”

Tong Feng nodded: "This couple... hey, do you usually read online novels?"

Han Ling: "I won't look."

“It’s quite profitable.” Tong Feng pointed to the computer. “The computer has a lot of information, including income records. When Dai Bin was writing traditional literature, he already earned hundreds of thousands a year. Now he’s been very successful as an online writer, earning two or three hundred thousand a year.”

Han Ling: "That's normal. Every industry has successful people."

Tong Feng: "I'm stuck here creating every day, no wonder my wife goes clubbing all night. She's just idling at home anyway."

Han Ling: "Your values ​​are problematic. Dai Bin is in it for the money, but that's not a reason for Xiao Yuxuan to mess around outside."

Tong Feng: "Okay, I take back what I just said."

After chatting for a while, the two arrived at the main room. The forensic work was almost finished. Sun Yujie and his team were still carefully examining the scene. They could see that the extraction of footprints went smoothly, and after comparison, some of them did not belong to the deceased.

"A few new footprints?" Ji Bowei asked.

Old Shen reported: "Two, one male and one female."

Ji Bowen nodded: "After we get back, we'll compare the footprints with those in the intentional injury case."

The female footprints may belong to Xiao Yuxuan, while the male footprints may belong to the person who stabbed Xiao Yuxuan. This needs to be determined first to avoid deviations in the direction of the subsequent investigation.

Old Shen: "Okay, I'll give you the results as soon as I get back to the branch office."

"Captain Ji! We've found something!"

Hearing the shouts outside, Ji Bowei left the main room and went to the computer.

The detective in the electronic evidence room pointed to the screen, which displayed the recovered chat history: "Daibin must have cheated on her with this girl."

Ji Bowei glanced at it; the girl's online name was "Gentle Little Elf".

Continuing to read the chat history, it becomes clear that the two are very direct and without any concealment, indicating that they are clearly in a passionate relationship.

“Pull it to the very top,” Ji Bowei said.

The officer used the mouse to navigate back to the time when the two had just become friends.

Ji Bowei looked at it slowly and soon understood that the girl was a loyal reader of Dai Bin, to the point of worship. Over time, the relationship between the author and the reader gradually turned into a romantic one.

During the conversation, Dai Bin repeatedly complained about his wife, Xiao Yuxuan, saying that she was just a pretty face who couldn't do anything else and couldn't provide him with any emotional support.

【Gentle Little Elf】posted a selfie, and judging from her looks, she is much less attractive than Xiao Yuxuan; she's just an ordinary girl.

However, Daibin was not disappointed at all; instead, he praised the other person as cute.

After reading through all the chat logs, Dai Bin's thought process became very clear.

When Dai Bin got married, he was already somewhat famous in the literary circle. While he wasn't extremely wealthy, he was certainly middle class. So, like most rich people, he chose to find a beautiful wife and keep her at home.

As time goes by, the flaws of a beautiful wife begin to emerge and increase, until eventually only her beauty remains as an advantage.

It's understandable that she doesn't do housework, it's understandable that she loves to spend money, and it's fine if she has a bad temper and princess syndrome, but looking down on Dai Bin's work crosses Dai Bin's red line.

You spend the money I earned by writing each word with such care, yet you call me a useless scholar and complain that my job isn't respectable enough.

Compared to his wife Xiao Yuxuan, the ordinary-looking "gentle little elf" is more attractive to Dai Bin at this stage. This is the result of the contrast and the soul resonance brought about by their shared understanding.

What you can't have always seems more desirable; what you don't have always seems better.

Of course, none of the detectives present thought Dai Bin's behavior was right; infidelity is infidelity. You enjoyed Xiao Yuxuan's beauty, then grew tired of her, regretted it, and began seeking psychological satisfaction from the "gentle little fairy"—can that be considered right?
This is a matter of opinion, and there is no definitive answer.

"Go and bring this gentle little sprite to the branch office."

Ji Bowei said.

The chat history was very detailed, including photos, names, phone numbers, and even home addresses, so there was no need to check it at all.

Regardless of whether the girl was related to Daibin's death, routine questioning cannot be skipped.

Infidelity is a common source of conflict, which can lead to criminal impulses; similar cases are not uncommon.

The sweet little fairy says she's single, and we need to verify that.

"Yes." The two criminal police officers from the squadron recorded the information and left.

Ji Bowei asked, "Are there any other clues?"

The officer replied, "Quite a few. Dai Bin was once embroiled in a plagiarism scandal, and he even argued with his traditional writer friends because he switched to writing online novels."

Regarding his debts, he lent money to three people, totaling approximately 150,000 to 160,000 yuan.

Ji Bowei frowned slightly.

This means there are many people with motives to commit the crime, making the investigation very troublesome.

Having many clues is a good thing; it's better than having no clues at all. We can just investigate slowly.

"Send the photos to the investigators," Ji Bowei said to the officers in the electronic evidence room, then looked at Han Ling and the others, "The interviews have already begun, you guys go and help out, focus on asking who came to see Dai Bin."

The men accepted the order, received the photos, and left.

Ji Bowei browsed Daibin's chat history with the gentle little elf for the second time, and at this moment he also knew why Daibin rented a house in the suburbs without his parents knowing.

In fact, not only his parents didn't know, but even his wife Xiao Yuxuan didn't know. Dai Bin only told his wife that he was going out to collect inspiration and seclude himself for creative work, and then he left.

This happened within the last two months.

The chat logs did not mention whether Xiao Yuxuan knew about Dai Bin's infidelity.

For a time, Ji Bowei did not have a clear judgment.

The current event sequence is as follows:

Xiao Yuxuan had a wild night out and was stabbed and seriously injured in the early morning.

Her husband, Dai Bin, went out to create in seclusion and died of poisoning in their rented apartment on the same day.

The gentle fairy is Daibin's mistress, and the two have already met in real life.

If these events are connected, it's difficult to piece them together without clues, and further investigation is needed.

There is also arsenic.

Chief forensic doctor Jiang Haichuan said that if it is suspected to be arsenic, it is basically confirmed, but it needs to be taken back to the branch office for authoritative toxicology testing.

Ji Bowei still trusted his old friend's judgment.

Arsenic is a highly toxic chemical and is strictly controlled by the state. No unit or individual may produce or sell it, and it is not easy to obtain.

However, in some remote rural areas, the illegal sale of arsenic absolutely exists, used to kill rats, rabbits, and pests.

The goods at rural markets are incredibly diverse; you can find almost anything you want to buy.

As I said before, laws and certain regulations cannot cover every corner of the country. For many villages, the effect of legal education is negligible, and an overall improvement in awareness is needed.

After exchanging ideas with his colleagues, Han Lingtongfeng was assigned to visit a certain area of ​​the village, trying to cover it as quickly as possible.

The cordon and the arrival of the police have attracted the attention of many villagers. The news spread quickly, and many villagers came out of their homes out of curiosity and to watch the spectacle.

The villagers were unfamiliar with Dai Bin, and they would only occasionally bump into him without exchanging any words. They only paid attention to their own family and relatives, and basically ignored others.

When the photos of the gentle little elf were shown, some villagers said they had seen them before, but they were also unfamiliar with them and had never interacted with them.

When Xiao Yuxuan's photo was shown again, this time no villager said they had seen her before.

When asked whether anyone from other villages had gone to look for Dai Bin, the difficulty of the question increased dramatically in the eyes of the villagers.

The village is located next to a provincial highway, with many vehicles coming and going and strangers frequently seen. Unless you pay special attention, it is difficult to obtain effective clues.

“Only that girl came.” On the way back, Tong Feng said, “Could it be that Dai Bin rented a house in the suburbs not only for his creative work but also for secret rendezvous?”

Han Ling: "You can ask Sun Yujie and the others about this. If the girl came to see Dai Bin multiple times and stayed for a long time, she would definitely have left many traces."

Or, you can just ask him directly; he's already been summoned.

Tong Feng nodded; he understood what Han Ling meant by "numerous traces."

A couple's time alone together can be very intense, leaving traces everywhere in the eyes of a forensic examiner.
