I'm not a genius detective

Chapter 126 The Entire Process of Death

Pan Xia left, and her son, Lü Zhanpeng, went into the detention room.

There was nothing wrong originally, but this is just asking for trouble for no reason.

However, it's good to teach him a lesson. Judging from Lü Zhanpeng's notebook, he really was planning to kill Du Juncai. If he gets his hands on potassium cyanide in the future, it will only take a moment for him to put it into action.

Lu Zhanpeng might not dare to kill someone with tools, as it would require a long period of psychological preparation. But killing someone with poison is different; once it's put in, the person dies—it's very simple.

This is similar to the future of electronic payments. There is a huge difference between buying things with cash and buying things with electronic payments; the latter is completely imperceptible.

The most terrifying thing is having no feeling; it easily leads to numbness.

Fangzhou reported the case, and then took the inquiry records and notebook to the Legal Affairs Brigade to discuss with his colleagues how to handle it.

Upon learning that the suspect was preparing to surrender himself to the police, the captain of the third squadron (criminal case review) under the Legal Affairs Brigade was quite surprised, doubting that he had misheard, and asked again before confirming.

“Preparing to commit a crime and surrendering… I recognize all six characters, but I don’t quite understand them when they’re put together,” the squad leader said. “Sit down, don’t stand.”

Fang Zhou smiled, stepped forward and sat down, and said, "There should be cases of people turning themselves in when they were preparing to commit a crime, right?"

The squad leader took the interrogation record and notes, nodded and said, "Yes, I remember a man who was planning to kidnap someone because of financial difficulties. He prepared tools, planned a route and selected a target, but stopped before the operation and turned himself in to the police."

This sounds hard to understand.

If you're planning a crime but haven't committed it yet, you can just pretend nothing happened. Why turn yourself in? It seems like a normal person wouldn't do that.

But it did happen. Surrendering oneself to the police after committing a crime has significant legal implications, and in the end, one will generally be exempt from punishment, depending on the severity of the offense.

If someone has prepared a bomb to take revenge on society, surrendering themselves in this situation may result in a suspended sentence.

The squad leader quickly finished reviewing the interrogation records and notes, his expression relaxed: "It's just a written plan, they haven't even prepared the tools. Let them go after the legal education session."

However, you need to thoroughly investigate whether he actually stole the potassium cyanide. The fact that the mother brought her son to turn himself in suggests that the son was not entirely willing from the beginning and there is a possibility that he was lying.

You are more professional in this area.

Fang Zhou: "Yes, we also need to be careful that Lü Zhanpeng's surrender this time is just to fool his mother, and that he will actually commit a crime after he gets out."

Squad leader: "Are you going to tell the target?"

Fang Zhou thought for a moment and shook his head: "No, it's better for Du Juncai not to know about this. When preparing to commit a crime, we usually don't tell the target to prevent escalating the conflict."

What would Du Juncai think and do if he knew that Lü Zhanpeng was planning to kill him? That remains to be seen.

From the police's perspective, not knowing is the best outcome.

After talking with the legal affairs team, Fang Zhou found Hu Lihui, and the group held a brief meeting in the case-handling hall.

Two things.

First, provide legal education to Lü Zhanpeng, clearly informing him of the consequences of murder, emphasizing that sometimes one cannot only consider oneself but also the future of one's parents.

While playing the legal card, we must also play the family card to nip crime in the bud.

Second, search Lu Zhanpeng's rented apartment, as well as his private workstation or personal belongings at his company, to determine whether he obtained potassium cyanide.

If everything goes smoothly, Lü Zhanpeng will be released within 24 hours. It's as if he just came to the branch office for a visit, leaving only a record and no criminal record.

"One investigation team is enough, plus two technical squadrons for trace evidence analysis," Hu Lihui ordered. "Fang Zhou, you, Han Ling, and Tong Feng go and investigate. First, check Lü Zhanpeng's rented house, then check the company. Try to get the results before dark."

Fangzhou: "Yes."

Hu Lihui went to the technical squadron to coordinate with two police officers, and the five of them left the branch office and headed to the residential area. The residential area was very close, only a ten-minute walk away, which is why Pan Xia came directly to the branch office to turn herself in, following the principle of proximity.

The name of the residential area is Ping An Garden.

More than half of the houses in Ping An Garden are resettlement houses, and the residents have varying levels of education and the environment is poor. This results in low housing prices and low rental prices.

People with limited funds often choose to rent in residential areas like Ping An Garden, where the quality of residents varies greatly.

Last year, the plainclothes police unit arrested a group of men and women suspected of prostitution in this neighborhood. They probably didn't catch them all, and there are definitely still some now.

Prostitutes operating on the same floor are very common and difficult to catch.

The five men weren't there to raid prostitution rings; each team had its own duties and naturally wouldn't concern themselves with such matters. They went directly to Lü Zhanpeng's residence and opened the door with their key.

The apartment has two bedrooms and one living room, with an area of ​​about 70 to 80 square meters. The furniture is simple but has everything you need, including a TV, coffee table, sofa, and dining table, which fully meets daily needs.

At first glance, Fang Zhou, Han Ling, and Tong Feng noticed the water dispenser in the living room, one of the tools Lu Zhanpeng had prepared for his crime.

The water in the bucket was almost gone; about one-fifth remained.

Looking around at the walls and high places, there were no cameras, which matched the statement.

"Spread out. You guys search the bedrooms, I'll just wander around the living room," Fang Zhou said.

The group accepted the order and entered Lü Zhanpeng's bedroom.

Lü Zhanpeng occupies the second bedroom.

This is one of Lü Zhanpeng's motives for murder.

Before Du Juncai arrived, Lü Zhanpeng lived alone in the master bedroom. After Du Juncai arrived, Lü Zhanpeng was moved to the second bedroom.

This is what honest people are like. To put it bluntly, they deserve to be bullied. Is it so hard to say "no"?
Now, the honest man is going to kill someone.

If Du Juncai found out, would he be so scared he wet his pants? There's a saying that goes, "Don't mess with honest people, or you might not be able to bear the consequences."

From a psychological perspective, the emotional accumulation effect of honest people is far greater than that of ordinary people. They use a repressive emotional management style for a long time, which can form a so-called "emotional dam". The amount of negative emotions they accumulate can be up to eight times that of normal people.

Eight times, once it erupts, it's like a tsunami, capable of anything.

Fang Zhou opened the refrigerator and searched for the capsules written in Lü Zhanpeng's notes. Lü Zhanpeng was quite quick-witted to think of using capsules to make ice. If this were to be used to commit murder in a public place with a large flow of people, it would really cause a lot of trouble for the police.

In some literary and film works, ice has always been a frequent subject of criminal cases.

It melts without leaving a trace, can be used for many things, and is highly adaptable.

Just like in a certain TV series, the murderer fixed the weapon with ice and then slammed it into the victim's back, thus committing murder from behind. Without an omniscient perspective, it would be hard to imagine that the victim died by suicide.

The search lasted for more than two hours. The five people searched very carefully, leaving no corner unchecked, including the bathroom, kitchen, and balcony.

After searching the house, we still need to check the storage room.

It was almost midnight when the sound of a key turning in the door rang out. Upon hearing this, Fangzhou immediately told everyone to stop and gather in the living room.

The young man walked in and was immediately taken aback to see five strangers inexplicably in the room.

"Huh? Who are you guys?!"

None of the five were wearing police uniforms.

"Excuse me, we're from the property management." Fang Zhou smiled. "We contacted Mr. Lü Zhanpeng before we came. The downstairs neighbors have been complaining about a leak, so we're here to check it out."

Upon learning it was the property management company, the young man's expression softened slightly, and the wariness in his eyes disappeared: "Oh... okay, have you finished checking?"

Fangzhou: "The investigation is complete. You're busy, are you working on Sunday?"

The young man nodded, said he was used to it, then went to the living room, threw his shoulder bag on the sofa, and casually picked up a water glass from the coffee table.

That's a personal water cup.

Han Ling walked at the back, deliberately slowing down to look at the young man. The young man took a water cup to the water dispenser, filled it up and drank it, apparently very thirsty after getting off work.

Ten seconds passed, and nothing unusual happened.

The young man sensed something, turned around and looked over. The two stared at each other for a second before Han Ling left.
He wasn't suspicious that the water was poisoned; it was just that Lü Zhanpeng had mentioned the water dispenser multiple times in his notes, so he subconsciously paid attention and wanted to confirm whether Du Juncai's drinking habits matched Lü Zhanpeng's records.

Potassium cyanide is a rapidly fatal poison. Symptoms appear within seconds and death occurs within minutes. Since Du Juncai is currently in good health, it indicates that the water dispenser is not poisonous.

The five people went downstairs to the storage room, and after the investigation, they still found no potassium cyanide, which meant that Lü Zhanpeng's words were credible.

Afterwards, the five of them found a place to have lunch and then headed to Lü Zhanpeng's company.

The company was a testing company. After showing their credentials, Han Ling and the other three went to check, while Fang Zhou chatted with Lü Zhanpeng's boss.

Let's first talk about Lü Zhanpeng's personality and character, and then discuss the source of potassium cyanide.

There are many opportunities to come into contact with cyanide in the company, such as in electroplating wastewater, cyanide testing reagents, and cyanide standard solutions.

Strict management is true, but if an employee wants to steal, it is still possible. Leaders generally don't expect an employee to steal cyanide to commit murder.

It's still a matter of tool theory; knives can be bought anywhere, it's all about the user's motivation.

If someone really wants to kill, there's no stopping them; there's always a way.

Around 4 p.m., the five returned to the branch office and reported the results to Hu Lihui.

Judging from the process, Lü Zhanpeng could be released before midnight tonight if things go smoothly.

5:40.

Peace Garden.

Du Juncai opened the door and came home with a shoulder bag on his back. After closing the door, he threw the shoulder bag on the sofa, habitually picked up the cup on the coffee table, and habitually went to the water dispenser to pour water.

He tilted his head back and gulped down the drink, then turned to look at the room where Lü Zhanpeng was.

"That's strange, where's Zhanpeng? He always comes home earlier than me every day, is he working overtime?"

After saying that, he looked at his cup again: "Why does this water taste so strange?"

Without thinking much, Du Juncai put the water glass back on the coffee table and prepared to go back to the master bedroom to rest. He hadn't taken two steps when a strong burning sensation exploded in his stomach.

It wasn't a stomachache, but a tearing, excruciating pain that came from the inside out.

He groaned, instinctively pressing his hand tightly against his upper abdomen, his body uncontrollably curling forward. He tried to scream, but a strong feeling of suffocation enveloped him.

My vision began to flicker and distort, and all I could see was a chaotic Venus, followed by a black wave.

A full-body spasm quickly began, muscles contorted, neck tilted back, white foam mixed with gastric juice spilled from the corner of the mouth, and skin color changed at a visible speed.

In just three minutes, Du Juncai's convulsions subsided, but the pain was not over. His nerves and muscles were failing, and his body trembled occasionally, but he had already lost consciousness.

Finally, everything came to a stop.

Du Juncai lay on the ground, his eyes wide open, pupils dilated, staring blankly ahead, his face frozen with the extreme pain and terror of his last moments.

The entire process was swift and brutal; a life was completely destroyed within minutes.
