Animal Detective

Chapter 414 The Thread
Shen Xin had only been to Qiongzhou when he was a child, so he naturally didn't have a relationship with Liu Jie.

But that doesn't mean you can't call for backup.

Zhang Hancheng said that if we needed anything, we should just contact him.

If he can't do it, then there's Zhao Hongjie.

If Zhao Hongjie can't handle it, there's still the provincial department, and Wang Peidong too.

At his level, how could his network of connections be small?

This really requires connections; simply sending a request for assistance might not be enough for them to investigate in such detail.

Shen Xin considered the next steps of the investigation.

We need to continue exploring the motivation aspect.

And so, He Liyuan was unearthed.

This proves that the direction is correct.

Back then, the task force did not conduct a large-scale investigation into Guo Meijing.

Secondly, the investigation in the three surrounding cities cannot be stopped.

Shen Xin speculated that Guo Jinhua might have purchased rat poison in Qiongzhou, but this was just speculation, and the investigation should not be halted based on a mere speculation.

We can't let those who finally managed to get a spot go to waste.

After returning from Donglin, Zhang Hancheng took Shen Xin to see Zhao Hongjie and gave a report.

Now that the case investigation has progressed this far, it's necessary to report to the leadership.

The main problem is that Zhang Hancheng doesn't have that connection.

In the office, Zhao Hongjie flipped through the investigation records and He Liyuan's statement, his expression growing more and more serious as he read.

He certainly remembered this case, but it remained unsolved and became a cold case. He had even criticized Zhang Hancheng.

But he never expected the case to end up like this.

A victim with severe aftereffects has become a suspect.

The speculations made by Shen Xin and others are also well-founded.

In short, it's about exclusivity.

They couldn't find any suspects, nor could they find a feasible way to poison the poison.

But if Guo Jinhua is the murderer, then all the questions are answered.

As for why someone would poison themselves as well as commit poisoning, Zhao Hongjie had encountered such cases of the thief crying "stop thief" before, so it wasn't surprising.

"Kid, you're good."

Zhao Hongjie put down his pen and praised Shen Xin.

"Better than you."

Zhao Hongjie glared at Zhang Hancheng again.

He then learned that Zhang Hancheng had the same idea back then, but he didn't dare to draw a conclusion and only secretly asked Chen Chao to do an investigation.

Now, Shen Xin dares to draw this conclusion, so in terms of courage and drive, isn't he stronger than Zhang Hancheng?

Zhang Hancheng nodded with a wry smile: "Yes, this kid is not bad."

Not only did they dare to make this judgment, but they also had enough ideas in investigating the motives. They thought of patients in the same ward and managed to find such a witness.

"Qiongzhou, right?"

Zhao Hongjie also felt it was necessary for Shen Xin to investigate Guo Jinhua's specific itinerary in Qiongzhou.

As for calling in reinforcements.

He thought for a moment, then suddenly remembered.

“Shen Xin, you should talk to Director Lin about this. I remember he mentioned that he has a comrade-in-arms in the Qiongzhou Public Security Bureau, but I don’t know his exact position.”

"But you're familiar with Director Lin, right? Ask him to put in a good word, and this will be easy to handle."

Shen Xin wanted to recruit people and pull strings, and Zhao Hongjie approved of that.

It is possible to send a request for assistance, but it is far less effective than simply making a call to a higher-level leader.

Especially since it happened to be in the Public Security Bureau.

It's just a matter of saying hello to Yaxian County.

Shen Xin nodded quickly.

I am familiar with Lin Weining's words.

Zhao Hongjie handed the transcript back, and couldn't help but praise him a few more times.

"I put you in charge of the unsolved cases office, and you did a really good job."

It hasn't been long, and we've already solved a cold case. This poisoning case we're handling is about to make progress as well.

Moreover, Zhao Hongjie also saw not only their case-handling abilities but also their team leadership and management skills.

The division of labor was clear, and the arrangements were well-organized.

Most importantly, Shen Xin also has the ability to integrate resources.

That means they'll call for backup.

In Zhao Hongjie's view, this is actually a kind of ability.

Police officers don't operate in isolation; they know how to request assistance and have the ability to mobilize available resources—this isn't something that can be achieved simply by talking. "Keep up the good work."

Zhao Hongjie gave them a look that said, "I think you're a good kid," and told them to go about their business.

As he was about to leave, Zhao Hongjie called Shen Xin back and asked how things were going with the police bird.

"I'm still waiting to see your performance."

"Director Zhao, don't worry, I'm training him every day."

If it weren't for Teddy, Shen Xin would have planned to go to Qiongzhou by himself.

Zhao Hongjie nodded. Several crows were flying around the municipal bureau compound. He wasn't blind; he could see them.

After leaving, Shen Xin called Lin Weining.

Shen Xin has his work phone number.

Shen Xin didn't answer, and didn't dare to bombard the phone with calls.

He is the director of a provincial capital city.

More than an hour later, Lin Weining called back.

They couldn't resist teasing Shen Xin, asking if he had changed his mind and was planning to move to the provincial capital.

If that's the case, he'll immediately pull some strings.

After hearing the explanation, Lin Weining immediately agreed.

This is no big deal to him at all.

His comrade-in-arms happened to be the chief of the Public Security Bureau's Security Division in Qiongzhou.

For those in real power, simply giving a word to their subordinates is incredibly easy.

Lin Weining's idea was to send someone from Shen Xin's side, and have them fully cooperate from the other side.

Yang Zeran is the most suitable candidate.

The next morning, Yang Zeran boarded a plane and headed to Qiongzhou.

Shen Xin remained in Nanjiang to continue his investigation there.

I originally thought that even if they used connections, it would still take some time to investigate the matter thoroughly.

After all, so much time has passed.

Unexpectedly, a discovery was made just the day after Yang Zeran arrived.

The video is open.

In the video, Yang Zeran was extremely excited: "Shen Xin, I never expected it to go so smoothly."

"It's like... like a ball of yarn. We found the end of the yarn, and suddenly everything fell into place."

He started nagging.

Shen Xin waved his fist at him: "Hurry up and say it."

Yang Zeran then said, "I thought about it on the way here. I'll check the courier company as soon as I land, but the courier company's records won't be kept for that long."

"The comrades in Yaxian helped me check all the express delivery points in the city, but no one remembered that Guo Jinhua had mailed anything."

"Then I thought, what if Guo Jinhua was hoping to sneak it onto the plane? That's a possibility."

"So I went to the airline, checked their records, and guess what happened?"

Even Zhao Tianxing, who was standing nearby, couldn't stand it anymore and told him to spit it out.

Yang Zeran said, "Shen Xin, you guessed right, this guy really did buy rat poison in Qiongzhou."

“I guessed right, he really was planning to smuggle it onto the plane, and one of the security personnel remembered him.”

“When he went through security, the rat poison he was carrying was discovered. He said he didn’t know the regulations and then tried to check it in as luggage.”

"The problem is that even shipping it by mail isn't an option, so he asked if there were any other solutions, saying that it was quite expensive and that it had some new technology that was effective."

"The female security officer said it definitely wouldn't work, but suggested I leave my contact information so she could mail it to him later."

"After considering it, Guo Jinhua agreed, and then the airport confiscated the bottle of rat poison."

Shen Xin interrupted Yang Zeran: "Bottle?"

Isn't it packaged in a bag?

Yang Zeran nodded hurriedly: "Yes, it's a bottle, it's liquid. I suspect it's the mother liquor of bromadiolone. I don't know where he bought it from. I need to investigate further."

"As a result, Guo Jinhua did not contact the security checkpoint again, and they did not take it seriously. They just kept the bottle of rat poison sealed."

"It wasn't until March 2015, after the Lunar New Year, that Guo Jinhua suddenly contacted the security checkpoint and found the female security officer from that time, asking her to help mail the bottle of rat poison."

"The female security officer was puzzled, saying that it had been half a year, and she was surprised that it was only now that she remembered."

"But she didn't think much of it and just sent the package as usual."

"Shen Xin, we've figured out the source of the rat poison. Next, as long as we prove that the rat poison Guo Jinhua got his hands on was the same kind that killed Fu Lanting, then the chain of evidence will be complete."

"Moreover, I think there is a great chance. Guo Jinhua said that he used some new technology, which is quite expensive. Maybe this rat poison has some special additives, or it is an exclusive secret formula."

After Fu Lanting's autopsy, a large amount of physical evidence was sealed and stored for future examination with updated technology.

Therefore, there are conditions.

Once the comparison is successful, then as Yang Zeran said, the chain of evidence is complete and irrefutable.
