Chapter 271

The so-called psychological profile is based on the understanding of criminal phenomena already formed by multiple disciplines such as psychology, sociology, and criminology.

It is an investigative act that analyzes physical traces at the crime scene, psychological traces, and the victim's life trajectory to delineate the characteristics the criminal is most likely to possess.

In some detective fiction, the situation of the criminal analyzed by the detective based on clues is often a type of "psychological profile."

Art comes from reality.

In the real world, it has long been common for police to analyze the specific characteristics of a killer based on the crime scene and the victim's situation.

It can be said that psychological profiling has provided a lot of help to the police.

But the facts are not absolute, because due to some "common sense" errors, some psychological profiles often produce certain deviations.

In Akiwara Yuto's memory from his past life, whether it was the Bai Yin case or the Hwaseong case, at the beginning, the best time for capture was missed due to errors in psychological profiling.

But after hearing Akiwara Yuto's request, Assistant Inspector Soma's expression became strange.

As a professional police officer of the Metropolitan Police Department, although he likes to watch some detective dramas in his spare time and is very fond of the TV series "Furuhata Ninzaburo" edited by Akiwara Yuto.

But he does not think that the other party, as a detective novelist, can really be of any help with this case.

However, Akiwara Yuto's social status is after all here, so he complained in his heart for a while but still gave him the stack of materials marked "Psychological Profile."

"This psychological profile was just made yesterday and is planned to be announced at the press conference the day after tomorrow. I hope you will keep it confidential before then, Akiwara-sensei."

Akiwara Yuto nodded, then took the portrait and began to look at it carefully.

After reading the whole thing, his brows furrowed tighter and tighter.

Because he found that this psychological profile was a bit presumptuous.

In the Hwaseong serial murder case of his past life, a large part of the opinion within the South Korean police regarding the killer was a "lonely bachelor" who was a psychopath.

But when the suspect was finally caught, it was discovered that the killer had already been married.

Besides the South Korean Hwaseong case, similar problems also appeared in the Hubei serial rape and murder cases and the Gansu Bai Yin case in China.

The killers finally caught all had some deviations from the police's imagination; they were all married and did not obviously show hatred and violence toward women.

Such errors in psychological profiling caused the police in these cases not to include the killer in the ranks of criminal suspects at the beginning.

It wasn't until DNA became popular and a large database was established that the real killer was caught.

And the "psychological profile" in Akiwara Yuto's hand defined the killer as a 25-35-year-old single man living alone, a pervert with violent behavior. This undoubtedly committed the same mistake as the South Korean police in his past life.

He was silent for a moment and expressed his inner thoughts.

"Assistant Inspector Soma, why not include married men as well?"

Assistant Inspector Soma glanced at him and said seriously: "This is the opinion of our criminal psychology experts. In their view, a man with a family would not commit such behavior."

"Not necessarily," Akiwara Yuto said: "If this person lives alone, he can completely avoid taking huge risks to carry out highly complex murder acts in the external environment."

His voice rose quite a bit, "The reason he did this might be because he lacks such an environment."

Assistant Inspector Soma was speechless and didn't know how to refute for a moment.

However, he felt a bit embarrassed and felt even more that Akiwara Yuto was being a bit meddlesome.

Even if the occurrence of the case affected your movie filming, you can't vent your emotions on our Metropolitan Police Department.

Besides, you are just a detective novelist, not a case-handling officer who really comes into contact with frontline case details; the opinions you put forward are too presumptuous.

Akiwara Yuto saw Assistant Inspector Soma's impatience, so he explained: "Assistant Inspector Soma, psychological profiling relies on criminal psychology, and the latter is a constantly advancing discipline that is updated every year."

"In criminal psychology cases in Europe and America, there have even been phenomena of dual personality."

"Under the psychology of dual personality, these killers can usually treat people politely and work diligently, hiding their cruelty under this performance. But in private, they produce killing desires with sexual drive and so on."

"So I hope to make a suggestion to the task force to include some married men in the DNA testing objects."

After hearing this, Assistant Inspector Soma hesitated.

In this era, Japan still has a heartfelt worship for Europe and America.

In fact, even the current police system was built by Americans who were sent to teach case-solving techniques.

So after Akiwara Yuto brought out European and American cases, he also took it seriously to a certain extent.

However, he still couldn't make up his mind about whether to suggest this to the task force.

Akiwara Yuto looked at his indecisive expression and said again: "Regarding the subsequent press conference, the Metropolitan Police Department must be under great pressure, right?"

Assistant Inspector Soma was silent and nodded.

A serial murder case that has never been solved has become a mountain pressing on the head of the Metropolitan Police Department.

As a result, there is another identical case now, which will inevitably make the public feel increasingly dissatisfied.

Under such circumstances, if this case still cannot be announced as solved, then the public's dissatisfaction will inevitably be further vented on the Metropolitan Police Department.

By then, being scolded as incompetent would be considered light! Maybe some councilors will even participate and propose to cut the budget!

Akiwara Yuto tapped the table with his hand and said in a deep voice: "If a socially well-known person expresses understanding and support for the Metropolitan Police Department, would it be of some help to you?"

Assistant Inspector Soma was stunned. If there is support from a socially well-known person, it can more or less play a certain role in helping public opinion.

"Akiwara-sensei, could it be that you..."

Assistant Inspector Soma looked at Akiwara Yuto with surprised eyes and asked in confusion.

Akiwara Yuto nodded but made a request.

"As the price for helping the Metropolitan Police Department, I hope to report my proposal to the task force and suggest that they go and look at the criminal psychology materials on dual personality."

Assistant Inspector Soma weighed it repeatedly for a long time, gritted his teeth, and finally agreed.

Akiwara Yuto looked at the other party's expression and sighed in his heart.

In fact, Akiwara Yuto's best choice now is to choose to give up the movie, withdraw the investment, and leave the crew.

Although more than half of the 100 million yen invested has already been spent, compared to the risks borne, this bit of money is nothing.

But just when he wanted to do so, he remembered the bitter pleading in Uchiumi Takuto's words and the shocking crime scenes he had seen before.

Under a special emotion, he decided to stand up and persuade the Metropolitan Police Department to change the psychological profile so that the killer could be caught sooner.

As for the movie "Memories of Murder," if the killer is never caught, he plans to keep it shelved and not release it even after filming is finished.

However, to tell the truth, although he put forward this suggestion, he also felt that the possibility of catching the killer was slim.

After all, with the population of eligible men in Kanagawa Prefecture being at least over a million, even if his proposal is adopted, it is nothing more than increasing some possibilities.

His mood was still a bit bad, so he bid farewell to Assistant Inspector Soma and left the Metropolitan Police Department...
