Chapter 173 Deep in Thought

Li Biao doesn't laugh!
Upon hearing the forensic doctor Lao Zhang's teasing, Li Biao's expression instantly turned into a meme.

If it weren't for the inappropriate setting, Feng Nan would definitely have laughed upon seeing Li Biao's current expression.

However, Feng Nan was in no mood to appreciate Li Biao's comical expression at this moment.

The current occasion is not quite appropriate.

Feng Nan carefully walked around the scene, comparing the clues in her mind with the scene one by one.

At the same time, Feng Nan was also thinking about how the murderer got into the scene.

Five years from now, the method by which the killer entered the scene remains a mystery.

However, the killer's method of leaving the scene had already been figured out.

The perpetrator left the scene through the window after committing the crime.

However, the investigation found no evidence that the murderer entered the room through the window.

This puzzled Feng Nan.

Surely the murderer couldn't be someone who could walk through walls and enter the room directly from the outside, right?

Even if the murderer really could walk through walls.

How could she risk her life to climb out of a fifth-floor window after committing murder?

Are they waiting for a CD?

It was utter nonsense; Feng Nan was almost amused by her own wild imagination.

Even if the murderer's ability to walk through walls had a cooldown, he wouldn't have needed to risk his life climbing down from the fifth floor.

The victim was murdered the previous day during the day.

The body was discovered the following day.

It was only after the guesthouse front desk couldn't contact the victim because the room fee had expired that they discovered the problem and sent room service over.

If the murderer stays in the room waiting for the CD, he can simply use the victim's phone to pay the room fee on time.

As long as the air conditioning is turned up cold enough, the murderer could stay here for two or three days without being discovered.

If too much time passes, it may not be able to hide it anymore.

The weather is hot and humid now, and even with air conditioning as a safety precaution, corpses will still cause problems.

Feng Nan came to the bedside and peeked downstairs.

With her keen eyesight, she immediately spotted a strip of cloth by the window on the fourth floor.

This piece of clothing that was torn off is key evidence that led to the conclusion that the murderer climbed the building to leave the scene.

As for why the evidence is that the murderer climbed the building to leave, rather than the evidence that the murderer climbed the building to enter the scene.

Coincidentally, the piece of clothing torn from the murderer's clothes happened to be stained with the victim's bodily fluids.

"and many more?"

"Isn't this too much of a coincidence?"

Thinking of this, a flash of inspiration struck Feng Nan.

Don't you think all of this is too much of a coincidence?

It was such a coincidence, as if it had been deliberately arranged.

Feng Nan frowned slightly, feeling as if she had grasped something.

But for a moment, she just couldn't figure out what point she was trying to grasp.

This feeling made Feng Nan very uncomfortable.

There's a kind of melancholy about constipation.

"Brother Li, call the surveyors over here."

“There was a piece of clothing outside the window, and there were also signs of climbing on the windowsill.”

"It might have been left by the murderer."

Feng Nan beckoned to Li Biao and spoke.

Although deep down, Feng Nan felt that this clue was a trap.

However, since this is the only useful trap in this case, she still has to extract it even if she feels there is a problem.

Upon hearing Feng Nan's words, Li Biao's expression brightened.

They immediately called in investigators to go to the scene and retrieve the piece of clothing.

Feng Nan moved aside from the window and continued to wander around the room.

The search is underway to determine the possibility of a new perpetrator entering and leaving the scene.

After seeing the clues about the future, Feng Nan always felt that it was a trap.

Is it a trap designed to lure them into investigating the case, or a deep one? Otherwise, a case like this shouldn't remain unsolved.

Unless the initial direction of the investigation was wrong.

In future clues, Feng Nan also mentioned that someone had suggested the investigation was going in the wrong direction.

But it had already been half a month since the incident.

At this point, we need to re-examine the site and readjust the direction of the investigation.

Much of the evidence and traces at the scene have been lost to time.

It's even uncertain whether the murderer is still in the city.

Therefore, Feng Nan had the idea from the beginning that this direction of investigation was the wrong direction.

Instead, they opened up a new direction for investigation.

Of course, this direction of investigation cannot be completely abandoned.

Because this research direction is not something Feng Nan can simply abandon.

If it's wrong, then it's wrong.

Neither Yueyang nor Li Biao would agree.

Therefore, parallel investigations are the only option.

Two or more research directions can be conducted simultaneously.

They tried their luck by casting a wide net.

After all, this case, though seemingly simple, has become an unsolved mystery for the next five years.

There's still something inside.

Moreover, this case is a series of related cases.

In six months, a year, a year and a half, two years—

Similar cases continued to occur for four and a half years.

The evidence and clues left at the scene were exactly the same as those in this case.

The case occurred over a period of six months.

In the future, Yueyang will also attempt to investigate the perpetrator's crime cycle.

Let's assume the murderer is someone who came here for tourism or business, and use that as a starting point for the investigation.

The perpetrator would leave the city immediately after committing the crime here.

However, this research direction is extremely difficult.

The flow of people entering and leaving Tang City at the same time through various means was simply too large.

It's no different from finding a needle in a haystack.

Moreover, after reviewing the future clues and investigation process, Feng Nan felt that this direction of the investigation was also wrong.

The perpetrator in this case never left the city.

So where exactly are you hiding?

Feng Nan glanced around the room, which was less than 30 square meters, and muttered to herself.

"and many more--"

"Tibetan?"

Feng Nan suddenly found the word "hidden" quite interesting.

Could the killer's secret to committing the crime lie in the word "hiding"?
"Old Zhang, when did the branch office start investigating the surveillance footage?"

Feng Nan turned her head and saw that the forensic doctor, Lao Zhang, had not yet left, so she immediately asked him.

As the first person to arrive from the Major Crimes Unit, forensic doctor Lao Zhang naturally became the person who handed over the case to the branch office.

Asking Lao Zhang if you have any questions is much more convenient than calling the branch office.

"Of course, the investigation started after the victim checked in."

"You don't actually think your colleagues at the branch office would make such a basic mistake as starting the investigation from the victim's estimated time of death, do you?"

"The victim wasn't even autopsied, so how can the time of death be determined?"

"Please, we forensic doctors are all professionals."

"And they are the most educated group in our system, how could they possibly make such a basic mistake?"

Forensic pathologist Lao Zhang was baffled by Feng Nan's question.

He said, both annoyed and amused.

Clearly, forensic pathologist Lao Zhang loves his profession and cannot tolerate anyone misunderstanding his work or his colleagues.
