Reborn in 1995, Criminal Investigation Records

The hormones Zhu Guolong added to his food were likely inspired by this.

The musty smell that the woman named Ya-ting detected was likely aflatoxin.

Based on Li Zhixia's identification, Qiao Kai may have had an improper or ambiguous relationship with the deceased Deng Fangfang.

All of this points to one conclusion—he is the murderer!

But there's no evidence!

There were no witnesses—it was late at night, and Feng Erhei only saw the other person's build, not their face.

The murder weapon was not found.

The motive for murder was there, but Zhou Yang felt it was somewhat weak, as if it was missing a tiny thread that could connect the dots.

Xiao Jiale almost opened his mouth, but seeing Zhou Yang's serious expression and furrowed brows as he thought about something, he could only concentrate on driving.

Around 7 p.m., the vehicle arrived at the Municipal Bureau.

As soon as the two arrived at the brigade's office area, Liu Chengyu handed a document to Zhou Yang.

There is indeed a person named Qiao Kai in Hongxing Village, Ping'an Town, Nanjiang Province. However, his father was disabled and passed away half a year ago, and his mother has cognitive impairment. Later, he was admitted to a vocational health school in a city under Nanjiang. It is said that he later went into business with a big boss and has not returned to the village for several years. Even if he sent a photo back, the villagers might not recognize him.

"Master, all the suspicions now point to this person named Qiao Kai!" Seeing Zhou Yang's solemn gaze, Liu Chengyu immediately gathered everyone together.

Afterwards, Xiao Jiale summarized today's itinerary and the questions he and Zhou Yang had asked each other, including Zhu Wenxuan's unusual behavior and the argument with Qiao Kai at the clinic, Zhu Guolong's ex-wife, Deng Fangfang's ex-husband, Zhu Wenxuan's profession, his observations at the pig farm, synthetic hormones, and the possible cultivation of aflatoxin.

When Zhou Yang looked up again, he found that everyone's eyes were on him, so he naturally looked at Liu Chengyu.

"Master, what did Zhu Guolong say?"

"Ugh, don't even mention it!" Wang Chao cursed angrily. "He won't say anything, he claims to know nothing when asked, but I know this old man has something on his mind, but he just won't say!"

Zhou Yang nodded. Through his visits over the past two days, he didn't think Zhu Guolong knew too much. At most, he probably had some suspicions. Such a person already had a certain social status. His wife was dead, and now what he needed to do was save face.

"How about we take care of Qiao Kai first?" Wang Chao tentatively asked Liu Chengyu and Zhou Yang.

Unbeknownst to him, he had already begun to seek Zhou Yang's opinion, something he himself hadn't even considered.

"No!"

"No!"

Liu Chengyu and Zhou Yang spoke up simultaneously, rejecting his suggestion.

"Fine, never mind!" Wang Chao shut his mouth reluctantly, his gaze shifting back and forth between the master and apprentice.

Qiao Kai is no ordinary suspect. If the speculation is true, then his counter-investigation capabilities, including all the steps in his premeditated scheme, are all interconnected. Such a person is not someone who can be frightened into confessing everything by a few scoldings. In fact, he might alert the other party, making them more cautious and allowing them to destroy evidence more quickly.

But where is the breakthrough?

Zhou Yang began to review his findings over the past two days. First, it was highly likely that Qiao Kai and Deng Fangfang were in a romantic relationship, which was supported by witnesses. Furthermore, clues could be seen from Deng Fangfang's actions.

Qiao Kai and Zhu Wenxuan are also a couple, which is common knowledge among their classmates.

Logically speaking, it's impossible for someone to like both Zhu Wenxuan, a college student, and Deng Fangfang, a middle-aged woman!

What if both of these purposes are to get in touch with Zhu Guolong?

That's too risky. What if those two meet? Wouldn't they both be exposed?

Judging from Qiao Kai's expression, Zhou Yang judged that he probably really liked Zhu Wenxuan, but what about Deng Fangfang?

If he really liked her, would he have stabbed her to death with his own hands?

Unless, of course, his contact with Deng Fangfang was to kill her? To take revenge on Zhu Guolong?

There's a problem, a big problem, between Qiao Kai, Deng Fangfang, and Zhu Guolong!

Thinking of this, Zhou Yang took out the information about Hongxing Village again and examined it word by word.

Suddenly!

His pupils contracted.

"Qiao Kai is not Qiao Kai!" Zhou Yang's voice wasn't loud, but it startled the others. What did he mean?

"The Qiao Kai in Hongxing Village is not the same person as the Qiao Kai I met!" Zhou Yang said with certainty.

Zhou Yang stood up and read aloud the information on Qiao Kai's father from Hongxing Village: "Qiao Qingzhu, male, born in 1940, level four disability, suffering from hereditary retinal network disease - CSNB!"

"Huh? What did you say?" Wang Chao craned his neck, his mouth slightly open.

"CSNB, also known as congenital stationary night blindness with myopia resistance, is what we commonly call night blindness. People with this condition usually have excellent or even superior visual acuity, but extremely poor night vision. This disease is a typical single-gene inherited disease with a very clear and strong heritability..."

Xiao Jiale stopped speaking immediately and looked at Zhou Yang.

"I know, I know! This Qiao Kai is not the same Qiao Kai at all, because the other Qiao Kai wouldn't be nearsighted!" Xiao Jiale looked at the glasses: "But this Qiao Kai is wearing glasses and committed the crime at night, something the other Qiao Kai couldn't have done!"

"Investigate!" A smile bloomed on Liu Chengyu's dark face. "Dig deep into Qiao Kai's background. I want to see who he really is!"

"Regarding this person's identity, I'd like to offer a few suggestions!"

Zhou Yang looked at Liu Chengyu: "The conventional way to investigate is to find people near Qiao Kai's clinic to find out the situation, but this is not very efficient. In criminal investigation, there is a lie strategy that is to say that when people lie about their address, they will subconsciously choose a place they are familiar with, because it is the easiest and safest, and they will also subconsciously leave a way out for possible 'investigation'."

Therefore, it is highly likely that this Qiao Kai has a deep understanding of Nanjiang, and may even have lived there!

The message from Nanjiang just now indicates that the real Qiao Kai attended a vocational school in Nanjiang. It's very likely that this imposter Qiao Kai went to the same school as him, or even knows him. I suggest investigating Qiao Kai's classmates, seniors, and juniors. If possible, get a list of schools.

Also, regarding Deng Fangfang, investigate Zhu Guolong to see if she knows any people from Nanjiang!

Today is the second day since the incident. Liu Chengyu did not arrange for any more rest days. Instead, he put everyone on the job and everyone worked together. They only ate a quick meal in the cafeteria before splitting up to carry out their tasks.

It must be said that as the investigation progressed, everyone's enthusiasm only grew stronger.

Many people watch movies and TV dramas and rarely see people going door-to-door at night to investigate, but in reality, it is quite the opposite; going door-to-door to investigate or even visit people at night is actually very common.

On the one hand, the success rate of finding people is high; on the other hand, people are more relaxed at home at night and are more willing to reveal more.

Finally, murder cases are major cases, and the first two days of investigation are the golden time to solve them. Even if it's only seven or eight o'clock now, if there are any clues, we'll be knocking on the door at one or two in the morning.

Soon, an urgent fax arrived at the municipal bureau office from Nanjiang, containing a list of students.
