After committing a thousand perfect crimes, he joined criminal investigation

Chapter 67: Solving the fingerprint mystery, new clues

"Pushing a wheelchair?"

Meeting Wang Gang's gaze, Gao Yi's expression suddenly became strange.

He has used this trick before!

In order to mislead the police in the direction of their investigation, Gao Yi pretended to be a disabled person, sat in a wheelchair on the road, randomly selected a "lucky passerby", and then used the dagger with fingerprints to create a perfect crime.

Of course, that high-righteousness was not to frame anyone, but to try a new crime method.

"Are you okay, Xiao Gao?" On the opposite side, Wang Gang, who saw Gao Yi's expression was wrong, immediately became worried. After shouting, he smiled bitterly and shook his head, mocking himself: "Do you think I have a persecution delusion?"

After all, how does the other party know that he will push him across the street?

Or, how does the other party know when he passes that road?

It’s too mysterious!

"Perhaps this is the closest guess to the truth."

But Gao Yi waved his hand and said seriously: "Captain Wang, can you still recall the situation at that time? The more detailed the better."

"Do you really believe that?"

Wang Gang never expected that Gao Yi would believe his guess. When he was stunned, he couldn't help but feel moved, so he thought for a while and said:

"It was after eight o'clock in the evening. I was returning home from get off work in the team. When I passed the traffic light on Hongshan Road, I saw an old man sitting in a wheelchair..." At this point, Wang Gang paused and seemed to be thinking.

After thinking like this for more than half a minute, Wang Gang looked at Gao Yi again and continued: "There were 10 seconds left on the green light. I saw that the old man had just pushed the wheelchair to the side of the road, so I went up and pushed it."

[Ten seconds of green light, I push my wheelchair to the side of the road and prepare to cross the road...]

Gao Yi reviewed what Wang Gang said. When the other party finished speaking, he immediately asked:

"Did you notice anything wrong at that time?"

"No."

Wang Gang shook his head: "When we reached the other side of the road, the old man said thank you. I was in a hurry to go home, so I responded casually without paying much attention."

"What about the armrest of the wheelchair? Is it any different from the handle of a dagger?"

Wang Gang had seen the photo of the dagger that killed Fukang before, so when Gao Yi asked this, he immediately shook his head:

"It's a plastic shell, about two centimeters wide, not much different from what you see in the photo."

It is precisely because of this, combined with the fingerprint, that Wang just thought of being in a wheelchair.

"Row."

Gao Yi hummed, recalling the extraction and restoration of the dagger's fingerprints in his mind.

The information clearly shows that Wang Gang is holding a dagger.

Therefore, after reading the information, Gao Yi speculated that if Wang Gang assassinated Fukang, he could only go to the opposite side of Fukang and stab him directly, instead of stabbing backward from one side.

The reason is also very simple. If the thrust is from one side, the straight thrust with an underhand grip is the smoothest, most effective and fastest.

It is impossible for a veteran detective like Wang Gang who has experienced many battles not to understand this.

And now, as Wang Gang thought of the clue of the wheelchair, Gao Yi suddenly thought of an unobservable detail in fingerprint extraction - the thumbprint on the dagger was concentrated on the belly of the finger, while the fingerprints of the other four fingers were except for the belly of the finger. There were also a few circles of surrounding fingerprints.

This is not a problem, even when it comes to Fukang's assassination case, it did not attract Gao Yi's attention.

But if combined with pushing a wheelchair, there will be a big problem.

Because when a normal person pushes an object with a handle, his thumb will instinctively press against the stick, allowing the five fingers and the stick to form a stable triangular structure.

At this time, if the object with the handle is too heavy, or when strength needs to be exerted, the thumb will provide greater support. In this way, the fingerprint of the thumb on the stick will extend outward except for the pad of the finger.

So at this time, there cannot be only fingertips on the stick.

On the contrary, for Wang Gang, pushing a wheelchair is not a difficult task, so he only needs to form a triangular structure to easily push the person and the wheelchair away. And the force is even throughout the whole process.

In this case, there will be a situation where there are only finger prints.

Thinking of this, Gao Yi's eyes became clear, and he came to a conclusion in his heart, so he began to ask:

"Captain Wang, do you still remember what that person looks like?"

"Appearance..." Wang Gang thought for a while: "My hair is gray, but I really didn't pay attention to what he looks like specifically."

At that time, it was just a matter of helping others. Wang Gang himself didn't take it seriously. Moreover, he was in a hurry to go home, so he didn't pay attention to what the other person looked like.

Having said this, Wang Gang looked at the serious-looking Gao Yi and couldn't help but ask: "Why, do you really think the fingerprints were left at that time?"

"Captain Wang, can you think of any other possibilities?"

Gao Yi smiled and shrugged, then became serious again: "Now it seems that the fingerprint matter is most likely related to what I want to ask."

"What are you asking?" After hearing what Gao Yi said, Wang Gang immediately became interested.

Could it be that Gao Yi discovered something?

As I was thinking about it, I heard Gao Yi say:

"I came here this time to ask Captain Wang about the theft gang. What did you find out?"

Beverly is associated with theft gangs.

The hallucinogenic drug methamphetamine was found in both Fukang and Zhou Jingjing, which had to make Gao Yi's imagination~

Is Zhou Jing also related to the theft gang?

Did the hallucinogenic drugs come from theft gangs?

"I actually found nothing!"

Unexpectedly, Wang Gang shook his head at this moment and expressed disappointment:

“Originally, we were following a car theft case, and we finally found the car successfully. That’s when I noticed the theft gang that had recently appeared in this county.

So I started to turn the direction of my investigation to this group of people, but as the investigation deepened, I found that this group of people was very mysterious, and their behavior did not look like a theft gang at all. "

"It's not like a theft gang..." Gao Yi's eyes lit up. He took a deep breath and stared at Wang Gang: "Then what?"

Gao Yi originally didn't think that the deaths of Fukang and Zhou Jing were a simple frame-up, but now it seems that he was right.

The source is likely to be the theft gang.

"Then I came in."

Wang Gang smiled bitterly twice, and then nothing happened!

But after smiling bitterly, Wang Gang thought of one more thing:

"But I received a text message the day before yesterday afternoon, asking me to meet at the abandoned cement factory in the south of the city at 11 p.m., so I got home from get off work at around 8 p.m., picked up something and hurried over, but I didn't see anything when I went there. people."

"Is he an acquaintance?"

Gao Yi asked immediately after hearing this.

Wang Gang shook his head: "It's an unknown number. If you call it, it will be empty."

"I waited until midnight and saw no one. The next day I went to the cement factory and waited for a long time while surveying the surrounding area. Not only did I not see anyone, I didn't even find any trace of a second person coming."

Later, Wang Gang even went to the communications department and checked the number in detail. In the end, he only found that the IP appeared once in Nghe An County, that is, when he sent a text message to Wang Gang.

Other than that, not even a single phone call was made.

There was no other way, so Wang Gang gave up.

Gao Yi listened to Wang Gang's story and kept thinking in his heart.

A minute later, Gao Yi slowly raised his head, met Wang Gang's gaze, and asked extremely seriously: "Captain Wang, have you ever suspected that the murder of Fukang was related to the theft organization?"
