Chapter 175 Incredible
Li Biao nodded upon hearing Feng Nan's words.

He immediately took control of the computer and pulled up the surveillance footage for the time point Feng Nan mentioned.

The surveillance video on the computer began to play.

Soon, a short and thin figure wearing a gray hooded sweatshirt appeared in the surveillance video.

Looking at the person appearing in the surveillance video, Feng Nan subconsciously narrowed her eyes.

eccentric!
Feng Nan found this person very strange.

Especially his gait.

It made Feng Nan feel strange.

It was as if he was deliberately controlling his gait and movements.

It feels a bit like a marionette.

At the same time, Feng Nan became even more certain of her previous guess.

If the person in the surveillance video is indeed, as she suspects, the murderer in this case.

Does such a thin guy really have the strength to climb down from the fifth floor?

That's obviously unlikely.

"Can you calculate this person's height and weight?"

Feng Nan asked.

"He is about 1.6 meters tall."

"Weight not exceeding 45 kilograms."

"Specifically, we can send someone to the site to conduct a comparison."

Before Feng Nan could finish speaking, forensic doctor Lao Zhang announced a category.

Feng Nan nodded, becoming even more certain of her guess.

A man who is 1.6 meters tall and weighs less than 100 pounds can only be described as thin and small.

Most girls of the same height are probably heavier than him.

"Brother Li, can a man with such a thin build really climb five floors?"

Feng Nan asked Li Biao.

Li Biao was visibly taken aback upon hearing this.

"If someone has received professional training, it is possible to do it."

Li Biao hesitated for a moment before speaking.

Feng Nan nodded: "That possibility cannot be ruled out."

"However, this should be considered a small probability and will not be taken into account for the time being."

"Let's continue watching the surveillance footage."

"You can speed it up a bit, just resume normal playback speed when someone enters or leaves the room."

Feng Nan said to Li Biao.

Feng Nan's new direction for the investigation is to tentatively designate this person as a criminal suspect.

Now that we have his physical characteristics, that's enough.

Now it was time to verify her other idea.

After watching the surveillance video, her suspicions were confirmed.

Perhaps she will have a way to figure out how the murderer entered the victim's room without leaving a trace.

Li Biao nodded upon hearing Feng Nan's words.

Following Feng Nan's instructions, the surveillance video was sped up.

The playback will only pause and speed up when someone enters or leaves the room.

Two days' worth of surveillance video, played at several times the speed, doesn't take much time to process.

Soon, the surveillance video on the computer showed footage from yesterday morning.

That is, the day before this person checked out, and before the victim checked in.

"Brother Li, you can restore the normal playback speed now."

"I want to see if this person actually left the room after checking out."

A cold glint flashed in Feng Nan's eyes as she stared intently at the computer screen.

"You mean?"

Upon hearing Feng Nan's words, both Li Biao and the forensic doctor, Lao Zhang, were stunned.

They both understood what Feng Nan meant.

"Let's see!"

"If this person didn't leave the room the latest, then he is the murderer."

Feng Nan nodded and spoke.

"I see!"

Upon receiving confirmation from Feng Nan, Li Biao and forensic doctor Lao Zhang both gasped inwardly. As time ticked down on the surveillance video...

Soon, it was twelve o'clock noon.

"Normally, they should have checked out by now, right?"

Feng Nan looked at the staff of the guesthouse and asked.

"Yes, even if the guest does not check out on their own, the system will automatically check them out if no renewal fee is received."

"Our cleaning staff will arrive within five minutes."

"Clean this room."

"If a guest leaves their luggage in the room, the housekeeping staff will bring the luggage to the front desk."

The guesthouse staff answered.

Feng Nan nodded: "Okay, what time did the victim check in?"

"I checked in at 12:30."

The guesthouse staff member answered.

As time passed, five minutes quickly went by.

Just as the guesthouse staff had mentioned, the guesthouse's cleaning staff also appeared in the surveillance video at this time.

The guesthouse cleaner arrived at the room door and knocked on it first.

They kept knocking for about two minutes until they were sure no one was in the room before the guesthouse cleaner entered the room's password.

Feng Nan and the others held their breath, their eyes fixed on the surveillance footage on the computer screen.

The guesthouse cleaning staff cleaned the entire room and replaced all the items with new ones before leaving.

Feng Nan and the others did not see the tenant leave.

"It sure is him!"

When she saw the victim carrying her luggage into the room, Feng Nan smiled confidently.

"This is the secret behind the killer's entry into the scene without leaving a trace!"

Feng Nan pointed to the surveillance video and said.

At this moment, both Li Biao and the forensic doctor Lao Zhang looked at Feng Nan with admiration.

The murderer didn't leave after checking out; he lurked in the room, waiting for the next guest to check in.

Who would have thought they were committing crimes?

"Xiao Nan, you've done it again!"

Li said with a smile.

"It's too early to celebrate!"

Feng Nan's lips curled up into a cold smile.

"Let's go back to the scene."

Feng Nan turned and walked out of the monitoring room.

Hearing Feng Nan's words, Li Biao and the forensic doctor Lao Zhang were stunned again.

Immediately, both of them showed expressions of shock.

"You mean the murderer is still hiding in the room?"

The two exclaimed in unison.

Hearing the exclamations of Li Biao and forensic doctor Lao Zhang behind her, Feng Nan revealed a smug smile.

Isn't this the ultimate meaning of the word "hidden"?

"But where is the murderer hiding?"

“The room is so small, and it was cleaned by cleaning staff before the victim checked in.”

Where could he be hiding?

On the way back to the room where the crime scene was located, forensic doctor Lao Zhang couldn't help but ask a question that had been bothering him.

"Just look and you'll find out."

Feng Nan said with a smile.

In fact, Feng Nan already had a guess about where the murderer was hiding.

However, she wasn't entirely sure and needed to go back to the site to check.

Just as forensic expert Lao Zhang said, the entire hotel and guesthouse is only that big.

Although this murderer is short, where could he possibly hide?
In addition to the cleaning services provided by the guesthouse, their on-site survey team also collected evidence from the entire site.

Most places where people can hide have already been seen.

There are only two or three places left that I haven't seen.

Feng Nan believed that as long as he returned to the scene, he would soon find the cunning murderer.

The premise is that, as she suspected, the murderer did not leave the scene.
