Chapter 943: The Upbringing Environment Matters A Lot

The third type: desire-control type.

Having control over the life and death of their victims gives this type of deranged criminal, this deranged serial killer, an extremely immense sense of satisfaction.

Because being caught led to the loss of their personal freedom.

So, they need to orally recount everything about their crimes, letting the police use that information to investigate and solve the case.

Look, whatever I say, the police have to follow up on it based on what I say. This is a form of psychological compensation, an alternative form of control desire.

The fourth type: committing crimes for many years, under extreme psychological pressure, hiding the truth, finally getting caught, and then pouring everything out all at once. Their heart feels comfortable, feels exhilarated.

There is also a fifth type, which is simply revenge, constantly revealing cases the police don't know about, keeping them running themselves ragged.

There are other types as well. In short, they come in all shapes and varieties.

Of course, there is also the type where, for certain reasons, their conscience awakens, and they confess and repent.

It's just that the probability of this kind is so small it can be ignored.

Which category did Tang Jia belong to?

Strictly speaking, he seemed to have a little bit of several types mixed in.

In any case, after he finished confessing the series of serial rape-murder cases he had committed.

He also confessed to tampering with the car, causing his ex-girlfriend and that man more than ten years older than her to die in a car accident.

This matter also shocked the police officers interrogating him quite a bit.

And when it came to why he did these things.

Tang Jia said it was all his ex-girlfriend's fault. She abandoned him. If his ex-girlfriend hadn't abandoned him, he wouldn't have gone to take revenge on young women of the same type as his ex-girlfriend, that is, young women who worked at nightclub bars, or who went there to play.

The police were certainly confused about this. After all, the victim of Tang Jia's last case was not some woman frequenting nightclub bars, but a single mother, a middle-aged woman.

Regarding this, Tang Jia's explanation was also very simple.

He had grown tired of playing with young women of the bar and nightclub type. He had originally planned to stop, but then he suddenly saw that middle-aged woman getting off her night shift, and she looked quite good, so he wanted to go have some fun.

When Tang Jia confessed all of this, his expression was calm. As for the bloody debts he had incurred, at least the interrogating police officers could not detect any guilt or regret whatsoever.

But they also couldn't detect that kind of wild joy or pride in his crimes.

Just as Yang Qi had previously analyzed.

Tang Jia was a paradox.

He was both addicted to it, and yet felt extreme agony over the cases he had committed. He knew it was wrong.

...

Nancheng City Police Station.

Professor Jiang and Zhou Wu were here, repeatedly watching Tang Jia's interrogation video.

Zhou Wu, Li Shumu's good friend, was also a criminal psychologist.

That message on Li Shumu's phone containing everything he had discovered about Alice Apartment was meant for him.

This showed their relationship was no ordinary one.

Professor Jiang, Zhou Wu's mentor, was a professor at Jiangnan University.

As a professor, and one in criminal psychology at that, he certainly had connections in this field.

Therefore, when someone suddenly reported to the authorities and a suspected killer was caught.

He immediately received the news, brought Zhou Wu along, and set off for Nancheng City.

Until now, when Tang Jia had confessed everything.

Everything had finally settled.

Only then did Professor Jiang couldn't help but sigh: "Zhou Wu, our chance at fame is gone..."

Regarding this rape-murder case, how many relevant professionals were analyzing it?

Doing all kinds of criminal profiling, employing what they had learned, hoping that what they provided could help the police catch the killer.

Using this to make a name for themselves, but everyone's plans had fallen through.

Unexpectedly, in the end, this killer was reported to the authorities by someone.

And the reporter was even his friend.

If not for his friend's report, who knows how long this case would have dragged on before ending.

"Teacher, although our plans fell through, at least our advance criminal psychology analysis and predictions about this killer were mostly accurate."

Professor Jiang touched his forehead with his left hand and said, "Mm, it also counts as proving our own abilities."

At that moment, the door to this room in the Nancheng City police station suddenly opened.

A middle-aged man in a police uniform strode in with large steps.

Professor Jiang greeted him. This middle-aged man was precisely the bureau chief of the Nancheng City police station.

"Thanks to that reporter, otherwise, who knows how much longer this case would have dragged on. You have no idea, during this period, the pressure on me was unbearable. I couldn't eat or sleep well, and I was even losing hair."

The bureau chief said with a smile as soon as he entered.

It was clear that Tang Jia's arrest and confession of his crimes truly made him very happy.

Professor Jiang nodded: "Indeed, we should thank him."

The bureau chief said: "Mm, but verbal thanks alone won't do. An honor certificate, and the reward money for the report, all need to be given to him, to encourage this."

The bureau chief's face then darkened: "Sigh, I've been thinking about a question lately."

"From when I was young and started working as a police officer, until now, I've read quite a few case files on serial murder cases, but in reality, I haven't encountered many. What I've encountered most are various cases of negligent homicide or vendetta killings arising from conflicts."

"Things like, various conflicts, vendetta killings, I can understand those."

"But this kind of serial murder, I truly cannot understand. If it were me, at most I'd go after someone I had a grudge with, but I wouldn't involve innocent people."

Professor Jiang said gravely: "What creates people like Tang Jia is sometimes psychological problems, but sometimes physiological problems, or both."

The bureau chief furrowed his brow: "Physiological problems? Shouldn't these kinds of people all be serial killers formed from psychological distortion?"

Professor Jiang shook his head: "The University of California, Irvine in America, has a neurobiology professor.

Named James Fallon.

He devoted himself to researching the physiological characteristics of serial killers, using PET brain scans on the brains of various serial killers.

He summarized one common point: the prefrontal cortex and temporal lobe activity of these serial killers were significantly lower compared to normal people, and these brain regions are responsible for conscience, empathy, and other such aspects.

Therefore, based on this, one could determine who is a serial killer.

Once, he accidentally gave himself a scan. It was supposed to be a routine health check, but he never expected in a million years that his own brain was actually similar to those serial killers.

He was then terrified and began frantically studying himself. How could he, a university professor, be a serial killer? He hadn't even abused cats or dogs!

Through his research on himself, he discovered that this wasn't his own problem, but his family's problem.

His family was a famous bloody murderer family.

Every two or three generations, a deranged murderer would appear.

And in this generation, it was him.

He took his relatives from the same generation and two or three generations back to get scanned. Only his brain had problems."

The bureau chief listened, curious: "But he didn't become a murderer, did he?"

Professor Jiang said: "Exactly. So, he was also looking for the reason."

"The final reason was also very simple."

"A deranged murderer is constituted as follows: an abnormal brain, dangerous genes, an unhappy childhood, exposure to violence and abuse."

"These are the factors that contribute to the birth of a deranged murderer."

"But this professor, although he possessed all the previous points."

"His upbringing environment was very good. His family was wealthy, his parents were both very normal, and especially his mother was very gentle, often gently guiding him. This kept him from going astray."

"So, in the end, he concluded that the upbringing environment is key. If there is a good upbringing environment, even if someone has genetic issues like his, they can still be like a normal person, and won't become a serial killer, a murderer."
