Through the investigation of his childhood files, we learned that Fang Guodong once suffered from porphyria, because of this reason, his parents divorced, and since then, he has been living with his mother.

His biological mother has always treated him badly, often beating and scolding and corporal punishment of Fang Guodong in front of his neighbors, calling him a wicked and monster, and not giving him food.

When Fang Guodong was 10 years old, he bit his dog to death in front of his neighbors, and then he was taken to the hospital for compulsory treatment.

Through the investigation of the other party's Guodong online banking account, the relevant technical personnel found that there were many transaction records in his account within this month, including several women's red clothes, two pairs of women's high heels, a set of customized knives, several body models, and some chemical raw materials.

And the chemical raw materials he bought are exactly the essential elements for the production of ether and that kind of biotoxin!

Looking at the information on the big screen, Fang Guodong's pale face and the slightly upward sly smile on the corner of his mouth, he unconsciously felt his scalp tingle. I really didn't expect that such a weak-looking guy, such a high-level intellectual with rich knowledge, would be the initiator of such a serial murder case!

What is even more terrifying than ghosts and gods is the human heart. Even if there were countless inexplicable supernaturals in the Black Gold Case, in the end, they were still no match for Fang Guodong's dark heart.

Six innocent women, three heroic police officers, what is human life to him?

After the above investigation, Fang Guodong was suspected of committing a major crime, and the police quickly locked his residence and formulated a detailed arrest plan.

After the plan was formulated, the conference room of the police station erupted in violent applause, and all the police officers who were injured in the welfare home that night, regardless of whether the injuries on their bodies were healed or not, all took the initiative to participate in the arrest operation.

For all the officers of the Black Gold City Police Department, they dreamed of arresting this murderous demon with their own hands.

Phnom Rim Glasses strongly invited me to participate in this arrest, during which he solemnly apologized to me more than once for what he had done before. With my strength, I have already let go of that bit of, and I naturally did not refuse his request.

Moreover, I also want to see with my own eyes what this murderous maniac is like at the first time.

"That, Comrade Gao Fei, can you do me a favor?" The gold-rimmed glasses are a little twisted, which is completely inconsistent with his 1.8 meter tall man, looking at his expression, I guess this matter must have something to do with Lin Xiaoxue.

"Say it."

"Well, I want to invite Lin Xiaoxue to participate in this arrest operation, so that she can see with her own eyes how I catch the prisoner, but she has already blocked my phone number, so I want you to help me call her. I haven't seen Xiaoxue at the police station for so many days, so I wonder if I miss her ......"

Damn, you're a dignified seven-foot man, you want to be a cool girl, you're embarrassed to go by yourself, and you actually asked me to help?

He shook his head helplessly, but still dialed Lin Xiaoxue's mobile phone. However, on the other end of the microphone, the prompt is to shut down.

Well? I thought about it, since she was taking care of Uncle Fang, then calling Uncle Fang, she could always be contacted. However, when Uncle Fang's phone was dialed, the other end of the microphone still showed that the phone was turned off.

This is a little strange, with Uncle Fang's character, the mobile phone will always be turned on, and it will be turned off today? I always felt that something was wrong.

Seeing this situation, the gold-rimmed glasses were a little scared, and muttered: "Nothing will happen, right, why are the phones of the two people turned off?" ”

"It's unlikely, the hospital is full of people from the city bureau, not to mention that Uncle Fang is looking at Xiaoxue."

"Uncle Fang, eh, by the way, I just wanted to tell you something. I always felt that something was not quite right with Uncle Fang. ”

"Something is wrong, what's wrong?"

Gold-rimmed glasses sighed and slowly spoke to me. It turned out that Liu Mei falsely accused me of recruiting prostitutes before, but in fact, Uncle Fang vaguely mentioned it in front of the gold-rimmed glasses, and the night I was inexplicably taken to the bamboo forest, it was Uncle Fang who said that there was a major discovery, so he transferred all the people in the police force.

In short, he always felt that something was not quite right with Uncle Fang, as if he had been deliberately hiding something.

I thought about it and thought that this should still be more hearty with gold-rimmed glasses.

Uncle Fang has made great achievements in the Heijin City Police Station, and he has been a police officer for so long, what should he do and what he should not do. He definitely has a sense of proportion in his heart, when he was in the welfare home, he was a person who desperately wanted to save Ji Huahua.

I guess the reason why the gold-rimmed glasses feel strange is just because Uncle Fang is more cautious, after all, he will retire in a few years. No veteran policeman wants to leave regrets in the last years of his career.

At this time, the round-up operation was about to begin, and Phnom Rim could only give up his desire to show off, take me with him to follow the big team, and set off for Fang Guodong's residence.

I was vaguely worried that things were going too smoothly after the orphanage. All the clues seem to come naturally.

What's more, when I was in the welfare home, I had already deduced that the other party should have an accomplice. But now, all the clues indicate that the black gold case was committed by Fang Guodong alone, and no second person was involved.

Strange, so weird!

The police car sped all the way and soon reached the target point. According to the data, after Fang Guodong returned to Heijin City, he has been living in a small courtyard next to an abandoned factory on the outskirts of the city. This courtyard was his childhood residence, which was originally waiting to be demolished and rebuilt, but for various reasons, it has been shelved there.

There were hardly any residents around the small courtyard, but a few scavengers could be seen everywhere.

The police had already set up surveillance wires around the courtyard a day ago, but for a whole day, Fang Guodong had not been seen. I still have worries in my heart, and Lin Xiaoxue and Uncle Fang's phones are still turned off, at this time, I can only hope that the subsequent arrest operation can go smoothly.

The black police car soon surrounded the small courtyard, which was even more deserted than I expected, and there was no one to see during the day, let alone at night, I really don't know what kind of people can live in it all the time.

The gold-rimmed glasses took out their firearms, kicked open the courtyard door with a headshot, and rushed in, and the criminal police behind followed in order, and I followed closely behind, without falling behind.

There was a smell of decay in the yard, and many plastic bags had been discarded in the surrounding mud, and when the bags were opened, they were found to be wrapped in the corpses of cats and dogs, some of which were already overgrown with maggots, and they were unrecognizable. Several younger police officers even threw up on the spot.

After the forensic examination, it was found that these cats and dogs had traces of being bitten by teeth before they were tortured and killed, and it was initially estimated that Fang Guodong caught stray cats and dogs near the yard in order to suck blood, and after killing, they were wantonly discarded.

"This pervert, it's really him!" Gold-rimmed glasses handed me a mask, put it on, and approached the room with me.

An experienced police officer approached and knocked lightly on the door, but it was unusually dark and unresponsive, not like a human being. Could it be that we are still one step slower, Fang Guodong has already absconded?

There was no time to wait any longer, the gold-rimmed glasses took the lead and rushed open the door, and then the police officers rushed in, and the appearance of this hut was instantly displayed in front of us.

The whole room gives me the feeling of clutter. There are also several mannequins at the door, all of whom are wearing that kind of red clothes on the models, and it is preliminarily estimated that they belong to the same style as the red clothes left on Wang Li's body.

In the living room, several old-fashioned long tables are all put together, on which are placed various chemical raw materials.

Molds, test tubes, bottles, droppers, you name it, it's like a small chemical factory! I clearly found a bottle of cyanide residue hidden in it, only now, the bottle was empty.

Gold-rimmed glasses entered the study room alone, where a large number of books on chemical and biological aspects were piled up. On the desk in the study is an old computer made in '98, and the screen also shows the status of screen protection, which looks like someone used it not so long ago.
