After gaining the entry-level observation ability, Gu Chen can observe the small and subtle clues. Moreover, Gu Chen can independently collect clues, which also shares the pressure on officer Wang and other colleagues.

The other old comrades, however, still need to complete their work with the cooperation of police officer Wang.

Although this seems to have team spirit, but also cumbersome, efficiency is sometimes not as good as Gu Chen's separate investigation.

After all, homicide is not an ordinary case, and the complicated environment of the dead also makes people feel anxious.

First of all, you have to understand the cause of the death of the victim and verify how the killer escaped from the chamber of secrets.

If it is said that the deceased deliberately created a false impression of homicide, then why should he be so stupid as to lock the door? Is this not to add trouble to himself?

Nowadays, people are under great pressure and have all kinds of weird ideas.

For example, a man in Jiangbei, after practicing lightness for 30 years, finally broke his leg.

No one believes this kind of thing, but it does exist.

This is the same when dealing with a case. After excluding all the possibilities, the rest, no matter how unreasonable, is the truth.

Gu Chen wiped the window glass with his hand, then reached out to officer Wang and several old comrades and said, "let's have a look."

"Very clean." An old comrade said.

"Since the dead is a slovenly and lazy fellow, how can the glass of the window be so clean? Have you ever thought about this question? " Gu Chen asked.

Everyone looked at each other, frowned one by one, and began to analyze various possibilities.

"Gu Chen." "Why did the police officer just say," you don't want to use the brain wall? "? If we can find the murderer and escape from the secret room without destroying the anti lock windows and doors, then we can confirm that this is a homicide. On the contrary, we can only commit suicide. "

Police officer Wang is not alarmist. If there is no reasonable explanation for many cases, he can only submit an investigation report in the most secure way.

After all, you can't say that after the murderer killed the victim, he used "wall piercing" to escape, right? There must be evidence in everything.

Gu Chen opened the bolt of the window, then touched the glass glue on the window and said, "the glass glue is obviously not the same color as the glass glue in other places."

"Color difference?" An old comrade also found the abnormality, he came up to have a look: "if you don't look carefully, you really can't see the difference."

"Yes, and there are traces of cleaning on the windowsill." Gu Chen first touched with his middle finger and turned over the clean side of his white gloves for everyone to check.

He then used his index finger to touch the corner of the window sill, and obvious dirt suddenly appeared on the white gloves.

"You mean Has the window been tampered with? " Officer Wang suddenly realized.

"That's right." Gu Chen followed the train of thought.

He first used an entry-level observation to detect such small doubts, and then used master level reasoning to start splicing the information together.

At this point, we can give a complete and reasonable explanation.

"I think there is a possibility." Gu Chen stopped for two seconds and said, "the murderer first used sleeping pills to put down the victim, then stabbed the victim with a dagger, then cut the glass window with a glass knife, then cleaned up the glass fragments on the windowsill, and finally jumped out of the window."

Gu Chen's reasoning is very novel and immediately attracted the attention of all the people present.

"You mean the killer escaped through the window?" Officer Wang's face changed slightly.

"It's impossible to lock the door back. I saw that only the window could be drilled into the room, so I focused on the window, and I found something fishy."

Gu Chen is very glad that his observation can capture the details that are easy to be ignored by ordinary people.

"According to your opinion, the murderer is outside. A new window should be installed."

At this time, an old comrade finally enlightened.

"So, the glass glue is new, and the color will be different from the previous one." Another old comrade followed his train of thought.

Officer Wang slapped his hands: "that's right. The murderer put the glass and the glass glue in advance by the window so that the dead would not be aware of it. After the assassination, he could disguise as a suicide in a secret room."

"Cutting the glass with a glass knife, drilling out, and then installing a new piece of glass, and adding glass glue, this method is not common people can do."

Gu Chen looked at officer Wang and continued to explain his reasoning: "as for the murderer, the most likely occupation is a glass erector, and he should be familiar with the dead."

"What if it's not a glass erector?" Another old comrade raised a question.

Every time Gu Chen puts forward a new conclusion, he will question it silently.

Gu Chen waved his hand and said, "it's OK. If you don't have it, you can go and check who has bought such large glass with him these days."Here, a group of people seems to have experienced the process from the maze to the exit.

The seemingly impossible situation just now seems much simpler when Gu Chen said so.

As for the details of observation, officer Wang has also made preliminary observation since he entered the door. However, it is not realistic to say that everything he has done is not realistic. There are always some places that he has missed.

But Gu Chen was able to make up for it.

His inference is based entirely on subtle clues, and then further observation is carried out, and the clues are closely linked.

This can't help but remind police officer Wang that he had been in the police force, and had followed Zhao Guozhi to deal with cases everywhere. To say that all kinds of complicated situations have not been seen before.

But if we followed our own thinking, it must start with how the trapped murderer escaped from the secret room, and once the doors and windows are locked, the investigation will be in a state of anxiety.

Now think about it, I just put forward "through the wall said" is really ridiculous.

Since the door can't get in and out, it must be the window, but Gu Chen can find out that the glass has been replaced according to this point.

And it can be inferred that the murderer was a glass erector who had a good relationship with the dead, or had bought glass and glass glue.

In this way, officer Wang feels that his police career in recent years has been in vain, and he is also ashamed of Gu Chen's observation.

Now take a look at Gu Chen. This guy is not only handsome, but also has amazing observation. He has almost reached the point of small and subtle.

If Gu Chen was not a probationary policeman, officer Wang even thought he was listening to a reasoning class just now.

Moreover, Gu Chen's reasoning logic is rigorous, and even can't find any fault.

"Officer Wang, senior brother Wang." Lu Weiwei, who just came in, waved to him: "are you ok?"

"I'm fine, but the murderer has something." Officer Wang regained consciousness, he looked at Lu Weiwei and said: "you go back to the police station and transfer out the identity information of the dead. I want to know who is in contact with him recently."

Lu Weiwei a listen, immediately exclaimed: "how is it me again?"

Officer Wang looked at Gu Chen and said, "would you like to go with her?"

"Goodbye! Make sure you get the job done. " Not waiting for Gu Chen to open his mouth, Lu Weiwei immediately agreed, the attitude change was caught off guard.

Lu Weiwei thought that it would be nice to work with Gu Chen every time.
