Conan's cross-dressing at the winery

Kasuga Lingzhuan walked beside him and continued to speak slowly.

"So the crime location is generally outside the buffer zone, and the approximate location of his lair can be determined based on the crime location.

For most people, their home is their home. Some people regard their workplace as their home, and some people have several homes at the same time.

For such a serial murderer, the place of murder and the place where the body is dumped are usually not in the same place!

At this time, if you want to determine the location of the murder, you must refer to the principle of least effort for ordinary people!"

Takagi followed Kasuga Ling and asked again with a confused look on his face.

"What is the principle of least effort?"

“The principle of least effort is an insurmountable laziness of human beings, and this applies even to things like throwing corpses. To put it simply, a corpse cannot be thrown very far.

When a body is moved from the place of murder to the place of dumping, it usually does not exceed 50 meters. If there is transportation, it may be extended to 50 meters away. However, generally speaking, the use of transportation also provides convenience for the search. At the same time, transportation

It will eventually become evidence.

Since there is no need for transportation, the murderer's process of transporting the victim's body will be affected by time, distance, speed and effort.

Then, by bringing in the basic information about how many kilometers per hour each section of the road is, the approximate location of the murder can be inferred.

However, if the corpse transportation journey encounters an uphill slope, then one hour will be added for every 500 meters. If it encounters a depression, one hour will be added for every 1,000 meters. If it is continued for 5 hours, one hour will be added due to fatigue."

Having said this, Chun Riling took Takagi's arm and looked back with a confident smile.

“Knowing the buffer zone of the murder route and the murder location, we can summarize the scope and pattern of the murderer’s activities, and successfully find his hiding place!

So, what are you waiting for? Just go and catch him!"

Takagi: "???"

what happens??

I'm just listening to you here to popularize science knowledge, why are you arresting people?!

Was the murderer found so quickly??!

The two got into the police car and drove to the vicinity of several crime scenes.

Takagi slowed down the car and asked Kasuga Ling, who was on the passenger side, "Miss Kuroba, where are we going?"

Chun Riling closed her eyes slightly and thought about the photos she just saw.

"The first case was found in a nearby park, and the time of death was approximately between 13:00 and 14:00 three days ago.

The location of the second case was in the alley behind the izakaya next to the university here. The time of death was between 21:00 and 22:00 three days ago.

The location of the third case was in the alley next to the Matsumoto Kiyoshi Jinbocho store, and the time of death was between 13:00 and 14:00 two days ago.

The cause of death in these three cases was that the bodies were dismembered, and there were no other signs of abuse, indicating that the prisoners were enjoying the process.

In this case, according to time habits, I think it is very likely that we missed a body and did not find it!"

Hearing these words made Takagi's hair stand on end and his skin crawled.

He suddenly shuddered, took a deep breath and asked: "You mean there might still be a corpse between 21:00 and 22:00 two days ago?!

If the murderer followed the time, then he should have missed three bodies...it might have been yesterday..."

"It's impossible!" Before Takagi could finish speaking, he was interrupted by Kasuga Ling.

Before Takagi could continue to ask, Kasuga Ling answered.

"Because yesterday was Sunday! Based on the time of the crime, it is inferred that the murderer is most likely an office worker between the ages of 30 and 40.

No office worker would want to be idle and busy when they have a break. They should all want to have a good rest!"

Gao Mu's bean-eyed eyes made him say "Ah" in embarrassment, "Is this like this?"

"Based on the time of death and the place where the body was dumped, we can probably get some information about the murderer.

He is most likely a programmer or someone who works in consulting, and has a base in places like Jimbocho, Yatagarasu, and Suidobashi.

Moreover, the body we missed should be somewhere next to this school. We just need to go there and ask if there is a foul smell nearby!"

Kasuga Ling pointed at the map and said.

Takagi came to his senses, slightly increased the accelerator, and the car rushed out at high speed.

"Ah, okay, I understand."

…

It arrived in a short while.

Kasuga Ling and Takagi got out of the car, and they kept searching the area.

One morning passed.

Surprisingly, there is no stinky place nearby.

"Damn it, isn't it like this?" Kasuga Ling frowned and picked up Takagi's phone again to look at the photos carefully.

Takagi stood aside and said helplessly: "If it is not resolved as soon as possible, the reputation of the Metropolitan Police Department will fall to the bottom. Those daily newspapers will definitely seize the opportunity to publish it."

Chun Riling looked at the time and became even more anxious.

What exactly went wrong?!

If a murderer wants to dismember a person, he will definitely need an environment that is very safe for him.

If you mark all the places of death on the map and connect them with a line...

If this line is extended, where is the most convenient place to place the 4th line while still using the shortest line?

Wait, no, no, no, let’s analyze again.

The time of death was 2 to 3 days ago.

Cause of death: The body was all dismembered and chopped into pieces.

The deceased were all young women, and they were all relatively cute.

The corpse was not the first scene.

The murderer's lightning attacks and killing methods driven by a strong desire for sadism!

The crime scene showed severe mental illness.

There was no sexual assault.

The body was destroyed, but there was no sign of pre-mortem torture.

His sword skills are very detailed and his behavior is serious and ritualistic.

The targets he chooses are easily accessible victims.

All crimes occurred on working days.

The murderer belongs to - the hunter.

Kasuga Ling stared at all the photos of the crime scene and observed them carefully.

No fingerprints, blood, hair or footprints of the murderer were found at the scene, which reflects that the murderer has certain counter-reconnaissance capabilities.

The profiling reasoning began in Kasuga Ling's mind.

"The murderer is a male, 28 to 37 years old, with low hair. He may have studied medicine or worked as a chef. He has an average IQ, but he has certain anti-reconnaissance capabilities.

I am single, have never been married, have difficulty interacting with others, and have a certain hatred for cute girls. I spend a lot of time during workday breaks and am very familiar with and accustomed to the surrounding environment. My personal hygiene is very good. I may be gay.

Takagi, report this situation immediately, I request a large-scale search! And the murderer will commit another crime soon!"

Chun Riling said seriously.

Takagi was stunned for a moment, and said helplessly: "No, a major drug trafficking syndicate was seized on Yueying Island yesterday, and most of the police forces are still there."

Hearing this, Chun Riling's mouth twitched.

Good guy.

Moon Shadow Island.

Wait, that's right, Kasuga Ling's eyes lit up, "Then invite the people from the Search Section 2 to come? They have nothing to do all day long anyway."

Takagi: "..."

Although she is right, I feel weird.
