After Gu Chen obtained entry-level observation, he could observe small clues, and Gu Chen's ability to independently collect clues also shared the pressure on Officer Wang and other colleagues.

As for the other veteran comrades who corresponded, they still needed to complete their work with the cooperation of Officer Wang.

Although this seems to be a team spirit, it is also cumbersome, and the efficiency is sometimes not as good as Gu Chen's individual investigation.

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

First of all, you have to understand the cause of the deceased's death, and you have to verify how the murderer escaped from the secret room.

If it is said that the deceased himself deliberately created the illusion that he was killing, then why should he be so stupid as to lock the door, wouldn't this be causing trouble for himself?

Nowadays, people are under a lot of pressure, and there are all kinds of bizarre ideas.

For example, a man in Jiangbei who practiced light skills for 30 years finally broke his leg.

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

This is the same when it comes to handling the case, after all possibilities have been ruled out, what remains, no matter how unreasonable, is the truth.

Gu Chen gently wiped his hand on the window glass, and then stretched out in front of Officer Wang and several old comrades and said, "Let's take a look." ”

"Very clean. An old comrade said.

"Since the deceased is a sloppy and lazy guy, how can the glass of the window be so clean?

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

"Gu Chen. Officer Wang didn't want to use his brains, so he asked directly: "What is the 'wall piercing technique' you just mentioned? If we can find the murderer and escape the secret room without breaking the locked windows and doors, then we can confirm that it was a homicide, but we can only commit suicide." ”

Officer Wang is not alarmist, and in many cases, if no reasonable explanation is given, the only way to do so is to submit an investigation report.

After all, you can't say that the murderer used the "wall piercing technique" to escape after killing the victim, right?

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

"Is there a color difference?" An old comrade also noticed the abnormality, and he leaned in to take a look: "If you don't look carefully, you really can't see the difference." ”

"That's right, and there's still traces of cleaning on the windowsill. Gu Chen touched it with his middle finger first, and turned it over with the clean side of the white glove for everyone to see.

He then touched the corner of the windowsill with his index finger, and the white gloves suddenly appeared visibly dirty.

"What do you mean...... Has the window been tampered with?"

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

He first used his entry-level observation to detect this small suspicion, and then used master-level reasoning to begin to stitch the information together.

At this moment, a complete and reasonable explanation can already be given.

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

Gu Chen's reasoning was very novel, and it immediately attracted the attention of everyone present.

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

"Because the locking door is unlikely, I looked in the room, only the window can drill people, so I stared at the window, and sure enough, I found some cats. ”

Gu Chen was still quite glad that his observation skills were able to capture details that ordinary people tend to ignore.

"According to you, the murderer is outside, and a glass window must have been reinstalled. ”

At this time, an old comrade finally got his senses.

"Therefore, the glass glue is newly added, and the color will be different from the previous one. Another old comrade caught up with the train of thought.

Officer Wang slapped his face: "That's right, the murderer put the glass, as well as the glass glue, by the window in advance, so that the deceased would not be aware of it, and after the assassination was completed, he could disguise it as a suicide in a closed room." ”

"Using a glass knife to cut the glass, drill it out, and then install a new piece of glass, and fill the glass glue, this technique is not something ordinary people can do. ”

Gu Chen looked at Officer Wang and continued to explain his reasoning: "As for the murderer, the most likely profession is a glass installer, and this person should be a little familiar with the deceased. ”

"What if it's not a glass installer?" another veteran comrade questioned.

Every time Gu Chen came up with a new conclusion, he would silently question it.

Gu Chen waved his hand and said, "It's okay, if you don't have it, you can go and check who has bought such a big glass with him in the past few days." ”

Speaking of this, the group seems to have gone through the process of going from the maze to the exit.

The situation that seemed impossible just now, when Gu Chen said this, it seemed to become much simpler.

If you want to talk about the details of observation, Officer Wang has also made preliminary observations from the beginning of entering the door, but it is not realistic to say that he has done everything, and there are always places that he misses.

But Gu Chen was able to successfully fill the gap.

The inferences he makes are based entirely on subtle clues and then developed by further observation, and the clues are very closely linked.

This can't help but make Officer Wang think that when he first joined the police force, he also followed Zhao Guozhi everywhere to handle cases, and it is not unheard of to say that he has never seen all kinds of complicated situations.

But if you follow your own train of thought at that time, 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 anxious.

Now that I think about it, the "through-the-wall theory" I just proposed is really ridiculous.

Since the door can't be entered or exited, it must be a window, but Gu Chen can find that the glass has been replaced based on this.

And it is inferred from this that the murderer may have been a glass installer who had a good relationship with the deceased, or had bought clues such as glass and glass glue.

Thinking about it this way, Officer Wang felt that his years of police career had been in vain, and he was ashamed of Gu Chen's observation.

Now look at Gu Chen, this guy is not only handsome, but his observation is also very amazing, almost to the point of being subtle.

If Gu Chen wasn't a probationary police officer, Officer Wang even thought he was listening to a reasoning lesson just now.

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

"Officer Wang, Senior Brother Wang. Lu Weiwei, who had just walked in, waved in front of him: "Are you okay?"

"I'm fine, but there's something wrong with this murderer. Officer Wang came back to his senses, he looked at Lu Weiwei and said, "You go back to the police station and bring up the identity information of the deceased, I want to know who has been contacting him recently." ”

When Lu Weiwei heard this, she immediately cried bitterly: "Why am I again?"

Officer Wang looked at Gu Chen: "Then you go with her?"

"Bye-bye! Before Gu Chen could speak, Lu Weiwei immediately agreed, and her attitude changed suddenly.

Lu Weiwei thought to herself, if she could be with Gu Chen every time she worked, it would seem to be quite good.
