North American Detective: I Am Proficient In All Kinds of American IAI

Read the newspaper.

Dean drew five or six circles on the city map, and numbers such as 1.2.3 were marked inside the circles.

Each circle represents a crime.

The numbers in the circles are the order in which they appear.

"The first case occurred in a remote park in the city, where public facilities were outdated and there was almost no monitoring. After the second case, they all appeared in the urban area, spreading in four directions.

The only area that doesn't appear is here! "

Dean picked up a pen and drew a big circle on a certain area on the map.

There is a high probability that the murderer lives in this area!

He turned to look at Corolla: "Have you found the information about the person who delivered the newspaper?"

A prison is not a private place.

out of humanitarianism.

The relatives and friends of the criminal can send some letters to the criminal.

But when these letters arrive at the hands of criminals, they will be opened, carefully checked by prison guards, and the sender will be registered.

Corolla nodded first, then shook her head: "According to the information provided by the prison, the sender's name is Jim. I asked someone to check the other party's information, and found that Jim was a distant relative of Xie Mi. He died eight years ago. Someone impersonated him. For more information, send a letter to Shamy."

"This is normal."

Dean was not surprised by this result at all.

From the fact that Xie Mi's accomplice chose to send a newspaper to remind Xie Mi, it can be seen that the other party is not that kind of stupid guy.

Information in newspapers is disjointed.

The interval between each delivery is also not certain.

Even more disgusting.

Every time Xie Mi found the information he wanted, he tore off that area, and then "glued" it to the indoor wall to ensure that the content of the newspaper on the side facing the people was normal.

In this situation.

Even if there was a certain prison guard who was suspicious of Xie Mi's weird behavior, he would never hold back his disgust and tear off the side of the wall where Xie Mi's descendants were stained with newspapers.

Because the duty of prison guards is to ensure that prisoners do not escape, not to solve cases.

Therefore, they will not have the sensitivity of police detectives who doubt everything and pursue all truths, and most normal people are unwilling to meddle in their own business.

"So where do you think you have the confidence to solve the case before you leave work?"

Corolla looked curiously.

"Isn't it obvious?"

Dean pointed to the circle without numbers on the map:

"The name of the sender can be disguised, but the handwriting on it cannot be disguised, and the address of the letter cannot be disguised either!

Help me get the mailing address of each letter, mark it on the map, further narrow the scope of the map, and then we can directly check the households one by one!

Xie Mi's accomplice is most likely living alone.

Even if we don't screen those residents.

Those residents will also leave their own handwriting on the property.

He can't escape! "

Hearing this, Corolla slapped her forehead, showing a sudden feeling.

Dean's method is a bit stupid, but with the help of modern tools, even if tens of thousands of notes need to be checked in the end, the efficiency is still not slow.

The only problem, is the tenant.

Property management companies generally take pictures of residents’ signatures and other documents and upload them to the Internet for information preservation. As long as they can get their information and compare them, it will be very fast.

However, some people who leave information are landlords, but there is no tenant information.

So when the time comes, it is estimated that it will take a little more work.

Corolla figured this out, and looked at Dean with admiration again: "I'm curious how your brain grows, it seems that no matter what, you can find a good breakthrough point in front of you!"

"It's actually not difficult.

A certain IQ plus enough experience.

Carola, your IQ is no lower than mine, but your vision limits your thinking.

Putting your head down and observing the world carefully will help you grow faster. "

Dean did not hesitate to teach this "junior sister".

Saliva doesn't cost money.

As long as Corolla doesn't have brain problems, its status in the Commonwealth should not be low in the future, and it is a potential stock.

This is actually the same as eating soft rice.

The pattern opens.

As long as you are not against yourself.

Dean enjoyed having some of these friends.

During the conversation.

A strange call came to Dean's cell phone.

Dean picked it up and saw that it was the Commonwealth's phone looking up. He hesitated for a moment before realizing that it should be a call from Nicole from the police station.

before leaving.

He left his business card.

Dean answered the phone: "Nico?"

"Yes, Mr. Dean, after working hard, we have re-examined the evidence left before, and we have made a major discovery!" On the other end of the phone, Nico's voice was a little excited.

Dean became interested: "Tell me?"

Although he already had the idea of ​​finding Xie Mi's accomplice.

But if you can save a little effort, it will be better.

"In this inspection, we have two major findings."

"First, on the rope that strangled the male victim, we found the skin remnants of Xie Mi and another unknown person from both ends and the middle!

We extracted the above genetic material.

Although the other party's information was not found in the database, after comparing the genetic material between him and Xie Mi, it was found that the genetic material between them was familial!

The other party is a relative of Xie Mi! "

Hearing this message, the bald face of Shamy's younger brother Gerlington immediately appeared in Dean's mind.

Did this guy cheat him?

Dean immediately winked at Corolla who was standing aside and listening.

Corolla understood in seconds, walked aside, took out her mobile phone, and prepared to call someone to find out where Gerlington was when his brother Xie Mi committed the crime!

over the phone.

Nico continued: "The second major discovery: We found cobalt on the bloody clothes, ax handles, and ropes on the female victim!"

"Cobalt element?"

"Yes, this is an uncommon metal element, the cobalt element that ordinary people can touch, and it is generally used in platinum jewelry, dental fillings, pigment configurations, etc.

The most important thing is that Xie Mi 'tipped' the female victim, but the clothes on his body did not detect the cobalt element, so the cobalt element is very likely to be left by the second person! "

talking.

Nico sighed.

Three years ago, they hadn't added an X-ray spectrometer here. Otherwise, even if they were careless and followed the inspection process, they would definitely be able to discover the massacre of family extermination three years ago, and there was an unknown accomplice!

After hearing this, Dean felt better.

With these two important pieces of information added by Nico.

Locking out accomplices just got easier!

He didn't care about Nico's sigh on the other end of the phone, and asked: "Generally, what other professions have been contaminated with cobalt for a long time?"

"Raw material workers, carpenters... that's right!"

When Niko mentioned the carpenter, he seemed to think of something, and exclaimed:

"Mr. Dean, I remember!

Three years ago, I made a comparison of the wounds on the victim's body, and found that although the ax wounds on the male victim and the ax wounds on the female victim were not comparable at all, they were produced in similar ways, just like wood chopping. work hard!

At that time, I didn't think there was an accomplice, so I didn't think much about it.

Now it seems that the accomplice must have the same work experience as a carpenter like Xie Mi! "

Due to the frantic felling during the Industrial Revolution, the surrounding cities did not have abundant tree resources, which could not support some professional loggers, and there were not many jobs that required the use of axes.

Cobalt element, always use an ax!

Combine these two points.

Basically, the accomplice can be identified as a carpenter!

"carpenter?"

Dean thanked Nico sincerely.

The other party's discovery was timely.

This really saved him a lot of energy.

hang up the phone.

Dean said to Corolla who was already busy: "Come on, let's find Gerlington!"

Corolla waved the phone:

"I have already verified that when Xie Mi committed the crime, he was detained at the police station and had no time to commit the crime!

Now that the murderer's occupation has been determined.

We only need to check according to your previous ideas, it will be easier! "

Dean shook his head: "The method I proposed before is not 100% correct, but since the accomplice is a relative of Xie Mi, and he worked as a carpenter together, Gerlington must know the identity of the other party!"

finished.

He helped Corolla, who has little life experience, conduct science popularization:

The profession of carpenter is amazing. No matter which country it is in, it is basically an apprenticeship model of one area or more. It is difficult to open classes for mass production and vocational training.

By the time Shaymi committed the crime, he had changed careers.

But his learning experience cannot be concealed.

And this apprenticeship.

Unlike normal jobs, which can be found through application, it is often introduced by acquaintances.

Considering that Xie Mi and his younger brother, both of their parents died, dropped out of school early to seek a living, there is a very high probability that Xie Mi will become a carpenter's apprentice in the end, and it is through the introduction of relatives.

This man, Gerlington, definitely knew it!

Dean said in a flat tone: "So, let's go directly to Gerlington, which saves a lot of time and effort compared to my previous method."

Corolla blinked her eyes and said in admiration habitually: "Dean, you are amazing!"

This girl with a monstrous IQ and lack of experience and cognition, in front of Dean, is about to become a salted fish who can only shout 666.

To this.

Dean silently took out a cigarette and lit it.

He also wanted to keep a low profile, but his strength didn't allow it.
