After committing a thousand perfect crimes, he joined criminal investigation

Chapter 5 Reasonable! So reasonable!
  "Yup!"

After waking up the dreamer with one sentence, Wei Qiang suddenly looked at Gao Yi with wide eyes: "You said you knew who the murderer was, and none of the questions asked during the interrogation were nonsense. Don't be too specific."

"Honestly, have you already considered the possibility of the fourth person escaping after committing the crime?"

After the words fell, in the interrogation room, Wei Qiang and Wang Gang both looked at Gao Yi with strange eyes.

If at the beginning, they only thought that Gao Yi was talking nonsense and did not think that he had found the murderer in the case.

So at this moment, after Gao Yi's interrogation was completed, combined with the new clues from the confessions of the two suspects Sun Hu and Sun Qiang, and Gao Yi's precise questions that seemed to witness the incident, they had to pay attention to Gao Yi's words——

【I know who the murderer is】

Could it be said that he really thought about how the murderer would leave after killing in the secret room from the beginning?
  "I have to say the murderer is very smart."

At this moment, Gao Yi no longer hid, he took out a few photos from his arms while talking.

Immediately afterwards, Gao Yi handed one of the photos to Wang Gang and said:

"But the Skynet is very sparse and there are no leaks. The murderer's secrets will eventually leak out."

"That's his flaw."

After saying this, Wang Gang took the photo and looked at it intently.

All I saw in the photo was a wall made of bricks with cement and white ash on the outside.

On the wall, there are two rows of vertical holes.

The environment in the photo is dark, and you can't even see the small hole if you don't look carefully.

However, as a veteran detective, Wang Gang quickly discovered this.

For a time, countless analyzes and speculations flashed through Wang Gang's mind, but in the end Wang Gang raised his head in confusion and looked at Gao Yi with the photo:

"This is?"

"What's wrong with this wall?"

On the side, Wei Qiang, who was leaning his head, also looked confused.

One wall, two rows of holes, what's the problem?

Don't you understand?
  Gao Yi shrugged as his eyes swept over Wang Gang and the two of them.

This is no wonder for them. After all, around the 21st century, many rural families would hammer nails into the walls to hang things.

So over time, many small holes will appear on the wall.

A very common phenomenon.

But these holes are different. Gao Yi pointed his finger at the top hole and gestured downward: "Connect the holes together and see what they look like?"

As he spoke, Gao Yi drew two lines from top to bottom along the left and right sides.

Wei Qiang touched his chin and looked at it with a frown.

"I see!"

Suddenly, an exclamation startled Wei Qiang. He turned around and saw Wang Gang, his eyes widened as if he had taken stimulants, and he pointed at the photo excitedly:

"Door nail! It's the door nail that's left behind!"

There are two rows of nail holes, arranged four by four in a regular pattern. Aren't these the wooden nails used to fix the door and door frame?

"Yes."

Gao Yi nodded and confirmed Wang Gang's judgment, and then listened to his unhurried description:
  "The murderer knocked out Sun Qiang, Sun Hu, and Sun Lei and threw them into the crime room.

Afterwards, the cabin’s only wooden door was covered with discarded fabric and a fake door was nailed to another wall.

After doing all this, the murderer disguised himself as Sun Lei until Sun Hu and Sun Qiang woke up. When they realize they are in danger, they will immediately choose to escape from the hut.

But what they faced was a false door that could not be opened. At this point, Sun Hu and his wife said that the secret room on the first floor where the people inside could not get out was officially established~"

In the interrogation room, Gao Yi's voice was not intense, as if he was stating something he had witnessed with his own eyes.

Gulu!

But on the side, Wang Gang was sweating coldly and his throat was crawling.

Swallow.

【Reasonable! So reasonable! 】

[He...is really a newcomer? Was it really just a trip to the crime scene? 】

On the other side, Wei Qiang’s scalp went numb~
  But before he could think about it, Gao Yi's voice came again:

"At this time, the fake Sun Lei stood up and suggested that the door be bolted from the inside to prevent danger late at night.

At this point, no one from the outside can enter, forming a second level of secret room.

But from beginning to end, they faced a false door.

The real door has always been covered, and you can go out and come in. Unfortunately, due to the darkness in the house and the panic, Sun Hu and the others did not notice this.

After that, Sun Hu and Sun Qiang were stunned again.

In order to ensure that the two would not become suspicious, the fake Sun Lei dragged the two to adjust their direction to confuse their understanding of the location of the fake door.

After doing this, the fake Sun Lei only needs to take the fake door and leave through the real door. "

"This……"

Wei Qiang took a deep breath after hearing this. In a daze, he felt that Gao Yi had described a moving scene of committing a crime.

After listening to it, I couldn't calm down for a long time. But at this time, Wang Gang opened his mouth and raised questions:

“But according to Sun Hu’s description and that of the reporter, the inside of the real door was indeed bolted shut, and the outside was also stuck by branches.

Qualifies as a double chamber. "

"Is it difficult to fasten the door bolt from the outside with a thin wire or something like that?"

As soon as Wang Gang finished speaking, Gao Yi asked with a smile.

Then, he took out another photo, which was a diagram of the inside of the wooden door where the crime occurred and the structure of the door bolt:

“This kind of door bolt only needs to be inserted into one door first, and one end is tied with a wire. After winding it a few times, the door bolt can be inserted into another door by dragging the thin wire from the outside.

As for the tree branches getting stuck outside, it's just a small trick. "

"Small means?"

When Wang Gang and Wei Qiang heard this, the corners of their eyes twitched.

Such a sophisticated means of committing a crime and such a wonderful design are actually just "little tricks" in Gao Yi's words?
  So what is the "big means"?
  "Captain Wang, what do you think?"

At this time, Gao Yi, who was a little hairy at being stared at, shouted softly.

"I...ah...cough~" Wang Gang finally came back to his senses. After coughing twice, he turned his attention to the case again:
  “Your analysis is very informative.

However, even if what you say is true, it seems we can't identify the murderer? "

Even if the murderer's modus operandi was exactly what Gao Yi said, who did it?

What's the motivation?
  There's no way to know for sure.

After all, the entire crime process left no direct clues at all.

But Gao Yi smiled and shook his head:

"Actually, the murderer was exposed during our conversation."

"Oh?"

Wang Gang was a little surprised when he heard this, and then he looked at Wei Qiang.

The two's brains were working rapidly, recalling what they had just discussed.

At this time, Gao Yi pointed to the photo of the door frame and door bolt again:
  “This kind of door bolt is heavy, and it is completely impossible to insert the inner door bolt from the outside with something like a rope.

This is also one of the reasons why the murderer asked Sun Qiang to lock the fake door bolt. "

The purpose is to make everyone think that the door bolt is firmly inserted.

"..."

At this moment, Wang Gang just felt that his brain was a little exhausted, thinking quickly about every word Gao Yi said.

Suddenly, he seemed to remember something, his face quickly turned red, and he said excitedly:

"The door bolt is not inserted properly, which means the door can be broken open from the outside."

Wei Qiang frowned and added:
  "According to the description of the reporter Sun Fang, the door could not be pushed open at that time. It was not until Sun Qiang and the others woke up that they pulled out the bolt and the door was opened."

"So, the problem lies here." Wang Gang said firmly.

Years of experience in handling cases allowed him to immediately smell the problem:

"For a normal person, if he realizes that an accident has occurred in the house, what is his first thought?"

"Bump into the door." Wei Qiang blurted out without thinking.

"That's right!" Wang Gang nodded heavily: "Instead of knocking on the door, wait until Sun Qiang and Sun Hu wake up, open the door bolt and go in."

"The murderers are the people who reported the crime, Sun Fang and Sun Jinyi!"

Wei Qiang suddenly realized.

That's it!

But Gao Yi shook his head at this moment:
  "Sun Fang is just an old woman. She has no financial or emotional involvement with Sun Lei. She should just go to the hut to do things.

She probably met Sun Jinyi by chance on the road. After that, the two discovered something unusual in the cabin and reported the crime. "

"This... you even analyzed Sun Jinyi's chance encounter with Sun Fang?"

"It's just the usual tactics."

Gao Yi shrugged.

Idiomatic?

Wei Qiang felt numb. He smiled bitterly and then looked at Wang Gang:

"Team King~"

"Summon Sun Jinyi immediately."

At this moment, Wang Gang did not hesitate at all, and said every word, sonorously and forcefully: "There is also Sun Fang."

"Yes!"

Wei Qiang took the order and took action immediately.

But at this time, Wang Gang's eyes fell on Gao Yi——
