Chapter 226 Case closed, upgrade (Part 1)

After reading the newspaper.

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

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 the public facilities were old and there was almost no surveillance. After the second case, they all appeared in the urban area, spreading in the southeast, northwest and four directions.

The only area where it doesn’t appear is here!”

Dean picked up the pen and drew a large 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?"

Prison is not a private place.

Dean picked it up and looked up and saw that it was a call from the Commonwealth. He hesitated for a moment and then realized that this was probably a call from Police Department Nico.

The most important thing is that Xie Mi 'raped' the female victim, but the clothes on his body did not detect cobalt elements, so these cobalt elements are most likely left by the second person!"

After hearing this, Dean felt wonderful.

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

"Mr. Dean, I remember!

Three years ago, I compared the wounds on the victims and found that although the ax wounds on the male victim and the ax wounds on the female victim were completely incomparable, their methods of exerting force were similar, just like chopping wood.

Work hard!

Help me find the mailing address of each letter, mark it on the map, further narrow down the map area, and then we can directly check the residents one by one!

"Isn't it obvious?"

But his learning experience cannot be concealed.

Dean immediately winked at Carolla who was standing aside.

Property management companies generally take photos of residents' signatures and other documents to preserve information and upload them to the Internet. As long as they can obtain their information and compare it, it will be very fast.

On the other end of the phone.

Although he already had an idea to find Xie Mi's accomplice.

But it would be better if we could save some effort.

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

Nico sighed.

“The name of the sender can be disguised, but the handwriting on it cannot be disguised, nor can the place where the letter is sent!

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

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

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.

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

Said.

Saliva doesn’t cost money.

Carola understood instantly, walked aside, took out her mobile phone, and was about to call someone to find out where Gerington was when her brother Semi committed the crime!

Even if we don't screen those residents.

Dean became interested: "Tell me about it?"

The only problem is the tenants.

Dean thanked Nico sincerely.

This really saved him a lot of effort.

Did this guy deceive him?

Because the prison guard's duty is to ensure that prisoners do not escape, not to solve the case.

And this apprenticeship inheritance.

Hang up the phone.

He didn't care about Nico's sigh on the other end of the phone and asked: "What other professions are generally exposed to cobalt for a long time?"

Just a certain IQ and enough experience.

Carolla waved her phone:

"I have verified that when Semi 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.

Carolla 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 Semi. He died eight years ago and someone used his name fraudulently.

For information, send a letter to Semi."

What's even more disgusting is.

Considering that Xie Mi and his younger brother both lost their parents and dropped out of school early to make a living, there is a high probability that Xie Mi ended up becoming a carpenter apprentice through the introduction of relatives he contacted.

A strange call came to Dean's cell phone.

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

It’s easier to lock down accomplices!

Upon hearing this message, Dean's mind immediately pictured the bald face of Semi's younger brother, Gerrington.

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 stupid guy.

This is actually the same as eating soft rice.

He can’t run away!”

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

The information in newspapers is confusing.

"This is normal."

Talking room.

Dean answered the phone: "Nico?"

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

Finished.

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

Dean enjoys making friends like this.

Cobalt element, often use an ax!

Xie Mi's accomplice is most likely living alone.

The other party's discovery was timely.

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 will still not be slow.

"Material worker, carpenter. That's right!"

"Yes, this is an uncommon metal element. Cobalt element is accessible to ordinary people and is generally used in platinum jewelry, dental fillings, pigment formulations, etc.

Relatives and friends of criminals can send some letters to criminals.

before leaving.

Dean said to Carolla who had finished her work: "Let's go find Gerrington!"

The time between each shipment is not necessarily certain.

I didn't think there were accomplices at the time, so I didn't think much about it.

Carolla clarified this and looked at Dean with admiration again: "I'm very curious about how your brain grows. It seems that no matter what happens, you can find a good breakthrough point in front of you!"

Therefore, they do not have the sensitivity of a police detective to suspect everything and pursue the truth. Most normal people are not willing to meddle in other people's business.

However, some people who leave information are landlords and do not have tenant information.

Three years ago, they did not add an X-ray spectrometer here. Otherwise, even if they were careless and followed the testing procedures, they would definitely have discovered the massacre of the family three years ago and an unknown accomplice!

Carola blinked her eyes and said in admiration out of habit: "Dean, you are so awesome!"

Dean said calmly: "So, let's go directly to Jerington, which will save a lot of time and effort than my previous method."

With these two important pieces of information Nico added.
