The train arrived in Tokyo soon. After saying goodbye to Ayako, Karasawa went to the Metropolitan Police Department and found Officer Megure to find out the situation.
He had briefly told the general idea on the phone before, and Tang Ze knew that during the time he was away from Tokyo, several luxury car arson cases had occurred in Beika-cho.
Because the arsonist only committed crimes on starry nights, he was also called the "starry sky arsonist."
Logically speaking, the arson case should have been the responsibility of Inspector Yuminaga, the "Fire Daddy", but after arriving at the Metropolitan Police Department and seeing the files, Karasawa understood why Inspector Megure, who was in charge of criminal cases, was in a hurry to call him back.
It is obvious that Inspector Megure called him back just because he was familiar with him. It was the people above who called him back to solve the case.
Because this arsonist has burned 22 cars so far!
Although there were no casualties, the incident caused a huge uproar. Coupled with the fact that the arsonist had not been caught, it led to public outrage and had a huge impact.
If that were all, it would be fine, but so far they have not figured out the criminal's modus operandi.
Not only that, witnesses once saw a suspicious police car appear at the arson scene.
In other words, the "starry sky arsonist" might be a police officer!
The impact was already huge, and the witness said it might be a police officer. Coupled with the fact that the case has not been solved for a long time, it is no wonder that Inspector Megure called him back.
After reading the file, Tang Ze pondered and said, "The criminal only targets expensive cars. Perhaps he hates people who drive luxury cars for some reason.
As for arsonists, most of them are the kind of people who cannot adapt to their work or the surrounding environment, and are unwilling to reveal their inner thoughts.
Simply put, they are people with low self-esteem and who are withdrawn.”
"I agree."
At this moment, a middle-aged man with a well-trimmed beard walked over and said, "I've heard a lot about Detective Tang Ze, and seeing him today, I can see he's truly worthy of his reputation."
"Who is this?" Tang Ze asked curiously, looking at the middle-aged man with extraordinary temperament in front of him.
"Ah, brother Tang Ze, let me introduce you."
Inspector Megure smiled and said, "This is Aihara Wataru, a contemporary of Mori.
This guy is quite outstanding. After studying at the FBI, he was noticed by them and invited because of his intelligence.
I've been with the FBI ever since.
Recently, the Metropolitan Police Department and the FBI had an exchange activity, so they sent him back to convey the most advanced "crime profiling" search methods from Meilijian to various departments.
Unfortunately, it was unfortunate that we encountered a series of arson cases here, so the exchange meeting was temporarily postponed.
Brother Aihara simply came over to help."
"So that's how it is."
Tang Ze suddenly understood: "I remember that criminal profiling is a method of investigating the criminal's gender, personality, work and family background, compiling statistics, and then using this as a reference to help solve the case."
To put it simply, it is to establish a file database of the same criminal, and then summarize what common features the same type of criminals have, in order to help the police solve the case.
However, this thing is somewhat similar to a fixed template routine and can be used as an auxiliary reference, but there will always be cases that do not meet the standards.
This thing cannot be made by one person. It requires official statistics of various data and a final summary. Otherwise, without credible data support, everything said is just a castle in the air.
"Detective Tang Ze is indeed worthy of being a famous criminal. He knows quite a lot."
Aihara Wataru smiled and said, "That's right, I came here this time to teach you the various statistics compiled by the FBI.
Take arson cases for example, the vast majority of those involved are between 16 and 28 years old.
His personality is just as Detective Tang Ze said, he is aloof and has low self-esteem.
They transform themselves into demons and destroy society or streets. When streets and buildings are set on fire, arsonists feel great joy and excitement.
"In other words, the criminal will continue to set fires?" Inspector Megure frowned when he heard this.
"I'm afraid that's right."
Aihara Wataru nodded and said, "Most criminals drink alcohol before committing crimes in order to enjoy the pleasure of arson.
The more he drank, the more violent and extreme his methods became. This twisted mentality is extremely terrifying."
"How could this happen?"
Officer Megure held his forehead with his hand, feeling a headache. He then looked at Aihara Wataru expectantly and said, "Brother Aihara, can we use criminal profiling methods to find out the criminal's residence?"
"The situation is different from country to country, so the data is also different."
Aihara Wataru replied, "In a beauty-themed fire, the culprit usually lives within 1.6 kilometers of the arson scene.
However, due to the different geographical environment in Neon, it is impossible to fully confirm this.”
"But no matter what, it's still of some reference value. Thank you very much!"
Inspector Megure thanked him and said, "The criminal has committed so many crimes. We can just cross-check and then expand the search area accordingly.
Brother Tang Ze, please investigate as soon as possible and inform me if you find anything!"
Knowing that Karasawa's actions were always unpredictable, Inspector Megure gave him some instructions and then hurriedly left, calling out to Aihara Wataru.
Compared to the reasoning that cannot keep up with Tang Ze's brain circuits, Aihara Wataru's conventional search method is more suitable for him.
Looking at the backs of the two people leaving, Tang Ze looked at Aihara Wataru's back thoughtfully.
For some reason, he felt that the conversation just now was familiar.
It felt like I knew the plot and was smoothly leaking information to guide others to investigate.
