Height 178.68 cm, weight 70.58 kg, foot length 25.62 cm, arm length 59.88 cm, leg length 93.57 cm...... Age 27 years old!

When this set of data appeared in Cheng Nuo's eyes, Cheng Nuo's face couldn't help but show a touch of joy.

All the data are within the margin of error.

This person is the only suspect that Cheng Nuo has found so far that matches all the data.

The more than 200 people that Cheng Nuo checked before were either wrong in height or wrong in weight......

Cheng Nuo's gaze locked on the figure on the computer screen.

That Cheng Nuo is the only "suspected murderer" found so far!

It was a young man, short-sleeved shorts, and a black baseball cap, and he looked ordinary, the kind that he couldn't find in the crowd.

However, what is more striking is that on the left hand of the young man, there is a tattoo of a tiger's head.

It can be clearly seen from the monitoring.

The time the killer came to the 14th floor was 9:10 a.m.

Then,It's been on the 14th floor.,Seemingly aimless wandering.。。

The 14th floor is a large video game mall, where he plays with crane machines and throws basketballs there.

At 9:36, Han Xiaoxiao came from the 13th floor to the 14th floor.

The surveillance footage shows that although the murderer has been walking around the video game city, he has been walking around that side.

Sight ......

Keep an eye on the staircase.

When he saw Han Xiaoxiao appear in his sight, the murderer's face was as usual, as if nothing had happened, and he continued to do what he should do.

Ten minutes later, at 9:46, the killer walked up to the 15th floor.

Monitoring, that's the end of it.

Cheng Nuo exhaled lightly and pulled his fingers. Pause the monitoring screen.

There was still a small section of monitoring Cheng Nuo who didn't look at it.

However, Cheng Nuo didn't want to waste time on the rest of the surveillance video.

Saving a little more time will allow the murderer to get away with it for a while.

"I've found the killer. Cheng Nuo turned his head and said in a calm tone to Bai Yan and Captain Yang.

"Oh, you've found the murderer. Captain Yang subconsciously responded lightly, but in the next second.

"Lie Lie Lie ...... Damn, you've found the murderer!!"

Captain Yang sat up directly from the chair, looking at Cheng Nuo with shocked eyes, and his trembling hands showed his inner unpeace.

Bai Yan also stood up directly from the chair and looked at Cheng Nuo not far away with a look of disbelief.

This guy ...... Wasn't he still napping just now?

How...... Why, in less than five minutes, the murderer was found?

Amazing！

"Yes, what's wrong, is there any problem?" Cheng Nuo innocently spread his hands, looking puzzled.

It's a basic operation!

Is it necessary to be so, to make a fuss?

"I'm just getting started, so it's a little slow, and it took more than half an hour. If you let a professional come, it shouldn't be ten minutes, right?" Cheng Nuo said modestly, and after speaking, he didn't forget to scratch the back of his head.

"Uh......"

Captain Yang and Bai Yan were directly choked by Cheng Nuo and were speechless.

Professionals?

Aren't the two of them just professionals?!

But let them go up, tell the truth, don't talk for ten minutes.

Even if they were given ten hours, they would be enough to find the murderer out of hundreds of people!

This guy ......

Bai Yan grinded his teeth and stared at Cheng Nuo fiercely.

If he could, Bai Yandu planned to detain Cheng Nuo in the police station for ten days and a half on the charge of "pretending to be forced".

Let him know. Pretending to be a criminal, but it's not good to be!

However, the top priority at the moment is to seize the time to apprehend the murderer.

It stands to reason that the longer the homicide drags on, the more likely it is that the killer will be caught.

This is also the reason why the 48 hours after the case are called "golden hours".

"Cheng Nuo, tell me, who is the murderer?" Captain Yang had already leaned over the computer desk at some point, and said to Cheng Nuo in a serious voice, "If you really help our police find the real murderer, the credit you deserve will not be missing." ”

Bai Yan also came to the computer screen, wanting to know if Cheng Nuo had really locked the murderer.

"That's it!" Cheng Nuo adjusted the surveillance screen and fixed the picture at the moment when the murderer just appeared on the 14th floor. Then, pointing to the plain-looking young man with a tiger head tattoo who appeared in the picture, he said in a conclusive manner.

Captain Yang and Bai Yan both looked at the person Cheng Nuo was pointing at, and then frowned at the same time.

They also can't know the truth of Cheng Nuo's words now.

Although Cheng Nuo's previous speculations have been proven to be without any mistakes.

But now, when faced with such a major issue as locking up the murderer, there is no room for the two to be careless.

So, Captain Yang glanced at Cheng Nuo and asked slowly, "Cheng Nuo, are you sure?"

Cheng Nuo shrugged, "Not 100% sure." ”

"But there's still 200 percent certainty. ”

Bai Yan: "......"

This guy, does he have that kind of illness that makes him uncomfortable if he doesn't pretend to be forced for a day?!

Seeing that the two of them still looked disbelieving, Cheng Nuo pressed the play button and let the monitoring screen continue to play.

The murderer stayed on the 14th floor for more than half an hour.

Since Cheng Nuo has already pointed out, that person may be the real murderer.

Therefore, when the monitoring on the computer screen began to play, the attention of Captain Yang and Bai Yan was always on him.

As time passed, with their years of experience as a police officer, they also discovered that something was wrong with that person.

That man's performance was really ...... Not quite normal.

Because, he didn't look like a customer who came to the 14th floor to play video games, but he was waiting for someone here.

For example, when he's playing with shooting.

I didn't shoot, and my face was like that. I hit it, but my face is still the same.

All the time in a state of absent-mindedness.

And his eyes kept looking at the staircase.

Ten minutes after the deceased went upstairs, the man also went upstairs.

By all indications.

Cheng Nuo suspected that this person did have the possibility of a murderer.

Moreover, the odds are not small.

"Detective Bai, what do you think?" Captain Yang began.

Bai Yan groaned, "I think it's necessary for us to investigate this person." ”

"I think so too!" Captain Yang said in a deep voice, "Detective Bai, you immediately go and investigate this person's information and the relationship with the deceased Han Xiaoxiao." ”

"Also, determine where this person is now. Don't let him run away right under our noses. Captain Yang slapped the table and said in a domineering tone.

"Roger!" Bai Yan stood up and shouted loudly.

"Cheng Nuo, classmate ,......" Watching Bai Yan walk out of the office, Captain Yang patted Cheng Nuo on the shoulder, and just wanted to say something, but at this moment, the mobile phone in his pocket suddenly rang......
