"These two people are the objects of my suspicion. According to the theory of criminal behavior, the probability that this middle-aged man is the robber is as high as eighty percent! His briefcase may not contain any documents, but a white flower...... Money!" Bai Yan looked at everyone and said with a pause.

"What, Detective Bai, can I ask a question?" Cheng Nuo raised his hand and said.

"Okay, you say. The corners of Bai Yan's mouth showed a faint confidence.

He still doesn't believe that a high school student's problem will not be solved by himself!

"What, I just want to say that the middle-aged man in the photo has one section less on the index finger of his right hand. Cheng Nuo pointed out Bai Yan's mistake very "kindly".

Bai Yan was stunned. Turning his head and staring carefully at the right hand of the middle-aged man holding the briefcase in the photo.

Sure enough, because the surveillance footage was a little blurry, Bai Yan was not carefully noticed at the beginning.

Now that I am staring closely, I can indeed see that the middle-aged man's right index finger is missing a section.

In the photo of the robber, the index finger of the robber's right hand is completely normal. Not a single section is missing.

Bai Yan: "......"

Bai Yan glanced at Cheng Nuo speechlessly.

This kid ...... How did you find out about this?

He himself had to put almost all of his face on the photo to find this detail.

And the distance between Cheng Nuo's position and the photo is at least three or four meters!

What Bai Yan didn't know was that Cheng Nuo's data ability, as long as it was an object within his line of sight, whether he could see it clearly or not, the data could appear in Cheng Nuo's eyes.

And Cheng Nuo was just collecting the data of the middle-aged man in the photo, and found that the length of his right index finger was somewhat abnormal, only 2.11 centimeters!

Bai Yan, who was demolished by Cheng Nuo, is now a little embarrassed.

In the last second, he just swore that the middle-aged man was one of the robbers, and the next second he was directly slapped in the face by Cheng Nuo's casual words.

This slap in the face...... Not too fast!

Facing the slightly suspicious gazes of Captain Yang and Jiang Lan, Bai Yan coughed in order to hide his embarrassment. Then he took a deep breath and calmed down a little like a beating. Pointing to the photo of the second robber.

"Now for the second robber, I found three suspects with physical characteristics similar to this robber. Speaking of this robber, Bai Yan obviously looked much more confident. "These three people were selected by me from thousands of people. I'm 100% sure. Among these three people was the robber we were looking for. ”

Whew!

Suddenly, after Bai Yan's flag was erected, Cheng Nuo slowly raised his hand.

Bai Yan's face froze, and he tried his best to make his tone appear calmer, "Classmate Cheng Nuo, do you have any questions again?"

"Oh, I have a little question. Cheng Nuo smiled, walked over to the whiteboard, and took down the photo of the second robber.

Then, he said unhurriedly, "Detective Bai, I found a problem, the arm length of these suspects you found is not the same as the arm length of the robbers. ”

"Oh?" Captain Yang on the side became interested. "Little brother, how do you see that?"

Although the two photos are the same size, the proportions of the people in the photo to the overall photo are not the same.

It's like the same person, a photo taken up close, and a photo taken from a distance. The size of the picture is the same, but the proportion of the person in the picture is not the same.

As a result, it is not possible to compare two different photographs with different proportions of people with a very accurate comparison. All Bai Yan can do is estimate an approximate value.

Facing Captain Yang's question, Cheng Nuo shook his head and smiled, "Captain Yang, someone can't do it, I can't do it." ”

A certain Mr. Bai Yan, who did not want to be named, turned dark.

"Do you know what my nickname is?" Cheng Nuo said, glancing at Captain Yang.

"What's it?" Captain Yang was very cooperative with Cheng Nuo's pretence this time.

"Detective Edogawa? Noonan!"

Edogawa ...... Nuolan?Ahh

Captain Yang looked confused!

Bai Yan hugged his arms and silently looked at Cheng Nuo, who had already begun to pretend to perform.

Keep showing!

I'll just watch you show with the second battalion commander's Italian cannon!

Cheng Nuo went through the data in his mind, took the photo with the No. 2 robber attached, and spoke.

"Based on the photos alone, we definitely don't know how tall the robber was, and what his arm length was. However, we can look at this. Cheng Nuo pointed to the floor tiles on the bank floor in the photo and said, "The specifications of the floor tiles in the bank are 300*400mm, that is, the length of the porcelain tiles is 40 cm and the width is 30 cm!"

"And the number of floor tiles covered by the shadow of the robbers is 3.54. Then the length of his shadow is 141.60 centimeters!"

"Qingcheng Bank Minjiang Road Branch, located at 120.3354 degrees east longitude, 36.0748 degrees north latitude, the time is 7:05 a.m., and the solar angle at this time is 32.14 degrees. ”

"The above data is calculated, and the height of this robber can be found to be 178.28 centimeters! According to the proportion, the robber's arm length is 0.3397 centimeters of his height, so his arm length is 60.57 centimeters!"

Cheng Nuo exhaled lightly and pointed to the three suspects found by Bai Yan and said.

"Let's talk about this man's arm length!"

Cheng Nuo pointed to the lamp pole next to the person in the photo and said.

"Generally speaking, these street light poles are of uniform specifications. So the height of the lamp pole can be determined, which is 8.00 meters! Because the camera, the suspect, the street lamp, the three objects are not in the same plane. Therefore, the height of the street lamp needs to be calculated by the angle. The angle of the street light and the camera is ...... After the calculation of the above data, it can be concluded that the arm length of the suspect is 58.35 centimeters! The difference of two centimeters is quite large. So exclude!"

"Okay, let's talk about the second suspect found by Officer Bai. Let's take the briefcase he holds in his hand as a reference. The size of the briefcase is 16 inches, which is 53.33 cm, and then ......"

Cheng Nuo was in front of the whiteboard, his mouth was like a river, and he analyzed the arm lengths of several people in the photo with reasonable evidence.

As everyone knows, Bai Yan and the three of them have already been stunned!

Needless to say, Jiang Lan, as Cheng Nuo's mother, watched Cheng Nuo crackle in front of the whiteboard and say a lot of numbers that she didn't understand at all, and she was shocked and relieved at the same time.

Look at how powerful my baby son is, he is more professional than the two policemen!

Bai Yan stood in place stunned, and the waves in his heart were tumbling. I didn't know what to say for a while.

If Cheng Nuo's long list of data is just nonsense, it's fine. But the key is...... The data is really well-founded.

For a while, Bai Yan was a little suspicious of the feeling of life!

Myself...... It's not even as good as a high school student?!

Well, you win!

You don't need to buy oranges for me, and you don't need to go all the way to move orange trees. Because...... Tangerine came over by herself!
