Chapter 226 closed, upgraded

  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 the public facilities were old and there was almost no monitoring. After the second time, they all appeared in the urban area, spreading all over the four directions.

  The only area that does not appear is here! "

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

  The murderer has a high probability and 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.

   Out of humanitarianism.

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

   But when these letters reach the 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.

  The information in the newspaper is messy.

  The interval between each delivery is not necessarily.

   Even more disgusting.

  Every time Xie Mi finds the information he wants, he tore off that area, and then "glue" it on the wall of the room to ensure that the content of the newspaper on the side facing the people is normal.

In this situation.

  Even if there is a certain prison guard who is suspicious of Xie Mi's weird behavior, he will definitely not hold back his disgust and tear off the side of the wall where the newspapers are covered with Xie Mi's descendants.

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

  So they will not have the sensitivity of police detectives who doubt everything and pursue all the truth.

   "So where do you feel confident you can solve the case before you leave work?"

   Corolla's eyes were curious.

   "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 written 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 likely to live alone.

  Even if we don't screen those households.

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

  He can't escape! "

  Hearing the words, Corolla slapped his forehead, showing a sudden feeling.

  Dean's method is 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.

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

  But some of the people who leave the information are landlords, but there is no tenant information.

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

   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 that difficult.

   A certain IQ plus enough experience.

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

   Put down your high head and observe the world carefully, which will help you grow faster. "

  Dean was not stingy with teaching this 'junior sister'.

  Drool and no 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 hostile to yourself.

   Dean likes to have 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 phone. 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!" Nicole's voice on the other end of the phone 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 discoveries."

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

   We extracted the above genetic material.

  Although no information about the other party was 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 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 was about to call someone to find out where Gerlington was when his brother Xie Mi committed the crime!

  The other end of the phone.

  Nico continued to say: "The second major discovery: We found cobalt on the **** coat, ax handle, and rope on the female victim!"

   "Cobalt element?"

   "Yes, this is an uncommon metal element, 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 cobalt element was not detected in the clothes on his body, so these cobalt elements are very likely to be left by the second person! "

   said.

   Nicole sighed.

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

  After hearing this, Dean felt better.

  With these two important pieces of information added by Nico.

  Locking up accomplices is even easier!

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

   "Raw material worker, carpenter. That's right!"

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

   "Mr. Dean, I remembered!

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 frenzied felling during the Industrial Revolution, the tree resources in the surrounding cities were not abundant, and they could not support some professional loggers, and there were not many jobs that required the use of axes.

  Cobalt element, always use an ax!

   These two points are combined.

  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 go find Gerlington!"

   Corolla waved her 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 speaking.

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

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

  When Xie Mi committed the crime, he had already changed careers.

   But his learning experience cannot be concealed.

   And this apprenticeship is passed on.

  Unlike normal jobs, you can find them by applying for jobs, often through introductions 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, Gerrington, 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 habitually admired: "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.

   About this.

  Dean silently took out a cigarette and lit it.

  He also wanted to keep a low profile, but his strength did not allow it.
