Animal Detective

Chapter 396 Poisoning Case
Shen Xin shook his head slightly. Without a thorough understanding of the situation, it was difficult for him to make any judgment.

Zhang Hancheng said, "Then you can study it. I have a meeting later, so let me know when it's time to take action."

It's not a big case; he only cares about the final test results.

After leaving the office, Shen Xin took Teddy to the Technical Investigation Detachment first.

At the far end of the corridor on the right side of the fifth floor, there is a mysterious department that is on the same level as the Criminal Investigation Division.

Technical police officers rely on their skills to make a living.

Normally I have a pretty relaxed job, but when something really happens, I have to work overtime day and night.

The department as a whole is young.

Other departments look at experience, but this department truly values ​​technical skills.

The squad leader's name is Liu Guoshuai. He's almost fifty, a veteran, and one of the first batch of college graduates in China, majoring in communications technology.

He helped set up the communications department in the bureau.

Later, he single-handedly established a technical investigation department, winning numerous awards and honors; his home was filled with certificates and awards that could fill an entire room.

He was a very amiable person with a square face, gray hair, and glasses. His demeanor was more like that of a senior engineer from a large corporation than a policeman.

The department is small, and most of the staff are young people.

When Liu Guoshuai arrived after hearing the news, a group of young people from the detachment were circling around Teddy, talking about Teddy's amazing flight on Mount Tai.

In the internet age, information travels too fast.

The flight took off the morning before yesterday. There were so many people at the scene, and many of them took videos, which are now circulating all over the internet.

The sight of Teddy Bear tumbling freely in the sea of ​​clouds resonated with countless people.

Everyone had the same feeling: handsome.

Then I wish I were Shen Xin.

Shen Xin explained his purpose: to install communication and filming equipment on Teddy, while minimizing any impact on his physical activities.

It can't be too big either; the smaller the better. It has to be a pinhole-level camera.

"How about we get him a hat, like this?" Shen Xin took out his phone to find a video for the group.

It's a falcon hat used for falconry, but it doesn't need to cover the eyes.

Like a motorcycle helmet, it can be put on his head without affecting the movement of his head.

Ideally, it should integrate a pinhole camera, battery, communication module, and speaker.

Having a loudspeaker would also make it easier for Shen Xin to give commands remotely.

This is the best solution.

The second option is to wear the locator that Chen Wanbin and his team installed on your body.

If that doesn't work, then put it on your leg.

After thinking for a moment, Liu Guoshuai asked Shen Xin curiously why he was doing this.

Afraid your Teddy will run away?
Shen Xin nodded, partly because he was afraid of losing it.

We can't keep an eye on him all the time. He has wings, and if he gets lost, it will be a huge problem.

Shen Xin explained his idea for the police bird.

"Ouch."

Liu Guoshuai gasped, exclaiming in surprise, "You're practically making bionic birds!"

He knew about those biomimetic birds, military-grade, used specifically for reconnaissance.

However, to his surprise, Liu Guoshuai nodded and said, "It's not impossible, after all, you're quite good at training police dogs."

There are probably very few police officers in Nanjiang who don't know that Shen Xin is skilled at training police dogs.

Liu Guoshuai crossed his arms and pondered for a moment before offering some ideas.

He thought it was feasible because the falcon wasn't a small sparrow; it was a large bird of prey with a large enough head.

Then the helmet can be made larger.

He believes that lightweight materials, such as high-density foam, can be used to create two layers of molds, with a space reserved in the middle for the sandwich layer. The corresponding equipment can then be installed and finally bonded together to form a lightweight helmet.

Since everyone here is in a tech field, someone immediately raised a question.

For example, when aiming a pinhole camera at a target, simply keeping it in the same direction as the bird's head isn't enough, because birds have an extremely wide field of vision and don't necessarily turn their heads when looking at something.

Someone suggested designing the pinhole camera at the chin, making it look like a real motorcycle helmet.

They also said that using one with a drive motor would allow for remote rotation.

Shen Xin thought about this problem for a long time yesterday.

I've only just realized that these people could think of the same problems I've thought of right away.

They've even started to consider actual application scenarios directly.

They huddled around the blackboard, chattering amongst themselves, discussing the best solution.

Since that's the case, Shen Xin doesn't need to say anything more; he can just wait to receive the finished product.

After taking Teddy's head and body measurements with their help, Shen Xin returned to his office.

Let's have a meeting first to sort out the work I did during my absence these past few days.

The poisoning occurred on September 11, 2015.

The victims were a married couple; the man's name was Guo Jinhua, and the woman's name was Fu Lanting.

The two opened a noodle shop near the Jinzhu Farmers Market in Tingyang Old Street.

At 8:42 p.m. on September 7, Guo Jinhua called 120, saying that his wife was having abdominal pain and vomiting blood.

He himself had the same problem, experiencing rectal bleeding.

An ambulance arrived and took the two to the nearby Tingyang Hospital Yunlin Branch.

After examination, the emergency room doctor confirmed that both men had abnormal blood clotting function and liver failure, while the wife's condition was more serious, with kidney failure as a complication.

At 10:20, they were transferred to the Municipal People's Hospital.

He was immediately declared critically ill.

The couple were transferred to the ICU, given K1 supplementation, and received artificial liver replacement therapy.

At nearly 9 a.m. on September 11, Fu Lanting died from DIC, also known as disseminated intravascular coagulation.

Guo Jinhua's symptoms were slightly milder, and he was rescued.

However, due to intracranial hemorrhage, he stayed in the ICU until the 16th before being transferred to a regular ward.

He was discharged from the hospital on October 4th, but was left with neurological dysfunction, hemiplegia, speech impairment, difficulty swallowing, as well as abnormal kidney function and chronic kidney disease, requiring long-term treatment.

When they were admitted to the hospital on the 7th, neither set of parents suspected anything, simply assuming they were both ill. It was only after Fu Lanting's death that her attending physician couldn't help but point out that their medical records were rather strange.

This wasn't actually the first time the two of them had received treatment.

On August 14th, the two went to the hospital once for gastrointestinal bleeding, dizziness, and palpitations.

Going back further, on June 28th, Fu Lanting had another medical record.

That time, she had bruises and purpura on her body, and her menstruation was abnormal.

I later consulted Guo Jinhua, and he said that he also had problems when Fu Lanting first visited him.

I felt weak and dizzy, and I had several nosebleeds in those few days, I don't know why.

The attending physician suspected that the two might have been poisoned.

The cause of the illness could not be found after the first two treatments.

Fu Lanting's mother then chose to call the police.

The autopsy revealed the presence of bromadiolone in Fu Lanting's body.

That is, rat poison.

It is a second-generation anticoagulant rodenticide, which works by causing rats to slowly bleed to death.

Further on-site investigation and sampling revealed no rat poison, confirming that there was no accidental ingestion.

Only at this point did the investigation begin as a poisoning case.

After several months of investigation, the poisoner could not be identified, and the case was eventually classified as unsolved.

This case was in the news and attracted considerable attention.

Because the couple ran a noodle shop, there were rumors that the murderer had been poisoning them for a long time.

So, during the poisoning process, could the poison be accidentally ingested by customers while the couple were doing business?
The two of them had been running this noodle shop for many years, and business was pretty good, with people coming and going.

So during that period, many people were quite frightened and went to the hospital specifically to check if they had been poisoned.

Because of this, the Municipal Public Security Bureau also established a special task force to solve the case within a specified time.

After eliminating one person after another, the poisoner was still not found.

Even the method of poisoning has not been confirmed.

In addition to Fu Lanting's death, Guo Jinhua suffered from aftereffects, including nerve damage, difficulty speaking, mental confusion, and an inability to clearly explain many things.

There was nothing that could be done, so it became an unsolved case.

Yang Zeran said, "The core issue is still the rat poison. Finding out where it was bought, who bought it, and locating the source of the poison is the most crucial thing."

Shen Xin agrees with this point.

To investigate a poisoning case, you must focus on the source of the poison.

At the time, considerable resources were mobilized to conduct multiple investigations into the sales of second-generation rodenticides throughout the city, attempting to trace the source of every package of bromadiolone that entered Nanjiang.

But this is too difficult.

Bromadiolone is the main active ingredient in second-generation rat poison, and there are countless brands produced using it, making it extremely difficult to find the right one.

After the three finished speaking, they all looked at Shen Xin.

Shen Xin snapped out of his daze and said, "Hey Yang Zeran, let's go out for a bit later. We have another case to handle."

"Yuwei, go to my house with Xing-ge, find my mom, pick up Damei, and see if you can find that cat."

Yang Zeran subconsciously asked what case it was.

Shen Xin didn't explain, but hesitated for a moment before saying, "Everyone, this case is quite troublesome. We need to be prepared that we might not be able to find out the truth."

This serves as a reminder.

There's nothing that can remain unsolved without a simple one.

The fact that a poisoning case can remain unsolved is comparable to the difficulty of solving a case involving strangers on the move.

This case has once again attracted considerable public attention. Shen Xin believes that the special task force must have done its utmost and investigated everything it could.

Therefore, Shen Xin was mentally prepared for the possibility that there would be no outcome in the end.

The reason they were willing to conduct another investigation was because the couple had a cat, and with their own abilities, there might be a sliver of hope.

Just a trace.

Three years later, it's unknown whether the cat is still alive.

Even if a cat is alive, it may not remember what happened three years ago.

Zhao Tianxing nodded and said he understood.

Ding Yuwei's gaze became more serious.

As for Yang Zeran, he simply sighed softly.

He now understands the difficulty of solving unsolved cases.

It's no wonder that some cases remain unsolved for years, or even more than a decade.

Shen Xin got up, told everyone to go about their business, and then called Yang Zeran to head to Jigang.

On the way, Shen Xin explained the details of the gambling case.

"So, what are your thoughts?" Shen Xin turned to ask him.

Yang Zeran crossed his arms, leaned back in his seat, and pondered for a long while before saying, "This car is nice. How much did it cost?"

There were two police cars in the office. Ding Yuwei and her team took one away, and the remaining police car was taken for maintenance, so Shen Xin drove his own car.

Shen Xin quickly rolled his eyes and said speechlessly, "We're being serious."

Yang Zeran said, "I'm being serious. I'm planning to get married at the end of the year, so I'm preparing to buy a car."

He looked around before saying, "It's just catching a gambler, it's not an urgent case."

"And who cares how the real and fake casinos are connected? Anyway, Zhang's goal is to see if Teddy can be used for reconnaissance. Once there are clues, just let Teddy out."

"Teddy can be spotted even by poachers on the grasslands, so finding a real casino in this tiny place like here is a piece of cake."

"As for how they did it, if you're really curious, just catch them and ask them."

In Yang Zeran's view, cases of cracking down on gambling are not on the same level as cases of poisoning.

Then he asked what functions the car had.

Shen Xin thought to himself that he really saw through things.

Shen Xin thought so too. This wasn't a drug case, just a regular gambling raid. The main purpose was to test Teddy's investigative abilities.
