No One Knows Ke Xue Better Than Me

One of them is devoted to psychological profiling.

According to the murderer's behavior, infer character, living environment, occupation, and even growth background.

Used in suspect locking, the effect is outstanding,

This strategy classification method is summed up by several future experts in psychological criminology.

In London in 1888, this method had not yet been born.

Suzuki Qiaoqiao hurry up and read the information in a race against time.

After thinking for a while, he asked:

"Officer, how many suspects did you arrest last time you blocked the Whitechapel area?"

At that time, it took a lot of trouble, and the result was no fruit.

Lestrade mentioned this, and his face suddenly felt dull:

"More than 1000 people, except for the elderly, children and women, there are 420 suspects left."

Suzuki Qiaoqiao thought about it and asked:

"Are you sure Jack the Ripper is among these people?"

Lestrade was offended, and his words went too far:

"After the homicide happened, I sealed off the scene immediately and invited the residents out. I would like to bet the reputation of the police. The murderer was among the more than 400 people!"

"Well, very spirited."

Suzuki Qiaoqiao nodded and pointed out the key point bluntly:

"Your screening methods are too backward to find Jack the Ripper."

The fellow police officer felt dissatisfied and retorted:

"Then tell me, how to find it?"

Lestrade wanted to ask this too, but he didn't expect to be preempted by his subordinates.

He folded his arms and looked like he was watching a good show.

The age of growth is different, the greater the communication barrier.

If Suzuki Qiaoqiao explains the principles of criminal psychology, the other party may not understand it.

Or try to speak human words, to be concise and to the point.

He went to the blackboard and wiped it clean.

Pick up the chalk and write while explaining:

"First, based on the location of the crime, Jack the Ripper lived near Whitechapel."

Hearing this, Lestrade rolled his eyes.

This simple reasoning, still need you to say?

Suzuki Qiaoqiao ignored them and continued to write while saying:

"Secondly, Jack the Ripper has escaped many times, and he can successfully blend into the crowd, and judge the mediocre appearance, neither ugly nor handsome."

"Thirdly, according to the threat letter mailed by Jack the Ripper, the wording is rigorous and there are few alterations. It shows that he has a good education in the past and is not an illiterate farmer."

"Fourth, Jack the Ripper always commits crimes at night, which means that he has a regular job during the day and is inconvenient to do it."

Lestrade saw that his analysis was eloquent, and gradually let go of his contempt.

Several other police officers in the room also focused their attention on Suzuki Qiaoqiao.

What kind of surprise can this unremarkable man bring to everyone?

"Fifth, Jack the Ripper's method of committing crimes is a surprise attack, not waiting for an opportunity. It shows that he is more introverted and reserved in interpersonal communication."

A police officer at the scene took out a notebook and started recording.

"Sixth, the victims are generally in their 40s and don't know each other. It can be seen that such retaliation is aimed at groups, not individuals. It is judged that Jack the Ripper is full of anger at female workers, and his mother is suspected of working in related industries."

Lestrade also paid attention to it and followed his subordinates to record.

Conan touched his chin with one hand, thoughtfully.

"Seventh, you don't need much surgical experience to open the rib cage. If the suspect's profession is related to the knife, you can focus on it."

"Eighth, Jack the Ripper is between 20 and 30 years old."

Lestrade stretched out his hand when he heard the words, looking like he was hesitant to say anything.

Suzuki Joe Bridge did not give this opportunity, explained:

"If Jack the Ripper was the same age as the victim, or 30 to 40 years old, it would be very reluctant to commit consecutive crimes and not run fast."

Seeing that he was finished, Lestrade put his hand back.

"Ninth, Jack the Ripper, between the ages of 20 and 30, attacked a 40-year-old woman, indicating a serious Oedipus plot. This can be corroborated that his mother was engaged in sex work."

"Tenth, disemboweled is the catharsis of violence, indicating that the daily life is very depressing and not very conspicuous."

After the psychological profile was completed, Suzuki Qiaoqiao knocked on the blackboard and ordered:

"Officer Lestrade, please divide the 42 police officers into 21 groups of 2 people, and investigate the suspects according to the above conditions. The remaining 8 people are divided into 2 groups to block important intersections in Whitechapel District and avoid the Ripper. Jack fled."

It is safer to investigate in groups of two than by one.

There can also be a relationship between them.

With this method of screening, there may not be many people left from more than 400 people.

Lestrade changed his previous attitude and became respectful:

"Mr. Suzuki, your reasoning is amazing!"

The police officer next to him who finished taking notes, followed with help:

"Yes, yes, as long as you analyze these ten points carefully, you can come to a conclusion. Damn, why didn't I think of it before?"

"Great, with this, we will definitely find Jack the Ripper!"

Conan felt a little embarrassed when he saw that everyone's confidence increased.

Fortunately, Suzuki Qiaoqiao can easily do things that everyone can't do.

"Alright, alright, time is running out, Officer Lestrade, please check in groups as soon as possible."

"Yes!"

A wave of psychological profile, plus big data investigation.

Rao is Jack the Ripper, no matter how cunning he is, he can't escape the French net.

The officers left the room in twos and threes, their excitement beyond words.

They have been accused and reviled by the public for a long time, and finally they have the opportunity to raise their eyebrows.

Lestrade can't wait to capture Jack the Ripper and complete the assembly as quickly as possible:

"Target, Whitechapel District, go!"

Chapter 346 Open the door and send warmth

Before leaving, Suzuki Qiaoqiao added:

"Police officer, the first wave of investigation should not be too purposeful. Ask simple questions first and relax the vigilance of suspects. After the first wave of screening, there will definitely not be many people left. When the time comes to block the escape route, you will be able to Find Jack the Ripper."

Lestrade waved his hand in high spirits:

"Okay, let's do it!"

……

"Ah, mother."

Allen sent another shot to the portrait and left the secret room contentedly.

Due to long-term manual needlework, his sexual ability is low.

Therefore, at the scene of the murder, he just vented, leaving no descendants.

"Dong dong dong."

There was a knock on the door not far from home.

"Open the door and do an investigation."

Alan followed the sound and grinned.

There's nothing these rubbish police officers can do, have they started to investigate?

If he could find it, he would have been caught long ago.

Allen flushed his face with cold water, but didn't take it to heart.

Not long after, there was a knock on the door:

"Open the door and do an investigation."

"Come here, now."

Allen responded, combed his hair, and opened the locked shop door.

There were two police officers standing outside, the older one was in his 40s, facing calmly.

The younger one is in his 20s, with a childish look on his face that cannot be hidden:

"Is it Alan Cosmins?"

"Yes, it's me."

The old police officer held a notebook and paper in his hands, without looking up:

"Ask you something and do a survey."

"sure no problem."

"Jack the Ripper has been active recently. He brutally murdered female workers, causing everyone in the jurisdiction to be in danger. I would like to ask, do you have anyone in your family who is engaged in related industries? Or do you know anyone who does this job?"
