Chapter 127

Shouzi held the photograph, compared it, and said, "Well, the fingerprint is indeed quite fragmented, but it's not impossible to find."

"Usually, the points I use for fingerprints are marked like musical notes. You set the direction at eight to ten points, or more, right?"

Chen Fan said, "Actually, six or seven are enough. After all, the probability of a match is too low. Such low-probability events aren't worth considering."

"Uh, forensic science is indeed a science, and your thinking is correct, but it won't hold up in court. You still need to find eight or ten points. However, I always look for seven."

Chen Fan stood to the side, listening quietly.

The old man was like a teacher, passing on his skills without holding anything back.

"Do you know about fingerprint reconstruction?"

Chen Fan joked, "Forget it, that's impossible."

"Look at you, didn't you just start by talking about big data?"

Chen Fan put away his playful demeanor, sat down quietly, and watched the old man's work.

He held the paper and, bit by bit, followed the lines, drawing downward.

It was as if he were writing a musical score.

When the old man had drawn enough, he finally opened the files of the fingerprints that had been set aside earlier.

"Well, this person."

Old Song took a look at the fingerprint and quickly called the bureau. The bureau notified them that this person had already gone to the train station.

Good grief, he was planning to run.

Shouzi asked from the side, "Which train station did he go to?"

"The East Station."

"Simple. Just call the Eagle Eye at the East Station and send the photo over."

Old Song slapped his own head and said, "Look at my memory. Eagle Eye is perfect for this."

Shouzi looked at Chen Fan and asked, "Can you understand it?"

"I can grasp the general idea. How many fingerprints have you looked at?"

"Tens of thousands, I suppose. I've been looking at them for so many years, constantly refining this method of mine. If you have time, you can try it. Although it doesn't rely on eight or ten points, it can still narrow down the scope, unless you encounter those strange cases."

Strange ones?

Chen Fan explained to the audience, "Eight or ten points are actually just to expand the fingerprint comparison data infinitely. In the human world, it's easy to see people who look very similar, or even identical, but there are still subtle differences. Only at eight, ten, or even fifteen points can you make a judgment. But such lookalikes are ultimately a small data set."

Chen Fan rarely took out his notebook to record these things.

"Thank you, Master."

"You're calling me Master now? Fine. Contact me if you need anything later. Don't rush; as long as that person enters the train station, Eagle Eye won't let him get away."

The group got into the car, and Old Song said, "We have a few unique individuals here. These people work in criminal investigation and rely on experience to track people. Shouzi is simple; he just looks at fingerprints. The other one, Eagle Eye, is even simpler; he just finds people."

"Finds people?"

"Yes. Anyone he has seen within three days, no matter who it is, he can remember. Any longer than that, Eagle Eye can't recall. He was amazing when he was young; he could remember everyone he'd seen within ten days. As long as he sees a photo, never mind a person, he could dig out an ant for you."

My god.

The audience was stunned. Was he really that awesome?

In the observation room, Qin Ming said, "Actually, Old Song was being conservative. You should know there are even more capable people. Earlier, to improve the efficiency of solving cases, we held competitions where they would take a thousand photos, shuffle them, and have these people piece them back together. Those were just minor events."

Damn, these people are monsters.

Hu Ge said, "It's a technical blockade, right?"

"Yes, there was a technical blockade in the early years, but we always had our own methods. Although clumsy, they worked. But clumsy methods are prone to errors. You know about the recent wrongful convictions, right? Actually, not every wrongful conviction involves power or such things. Many times, these cases are caused by backward technology and backward thinking."

After all, it's people who solve cases, not machines.

The group arrived at the train station at a leisurely pace, and the person had already been detained by Eagle Eye.

Holding a walkie-talkie, Eagle Eye sat to the side eating melon seeds, while the person was squatting on the ground.

"Long time no see, Old Song."

"Long time no see. You're still the best."

"Machines are useful, but if someone covers their face, machines fail. Makeup doesn't work well either. Sigh, in the end, you still have to rely on people."

Chen Fan couldn't argue with that and asked, "What is your judgment?"

"Chen Fan, the new forensic genius?"

Chen Fan nodded.

Eagle Eye said, "Let me tell you, this skill of identifying people is a profound science. There's so much to it. Listen to me, and I'll tell you slowly."

Old Song was speechless and said, "Zhang Tianxiong, you follow him. I'll take the person back first."

Eagle Eye didn't speak very fast, and Chen Fan took out his notebook to record it bit by bit.

Height, weight, physical characteristics, and so on were presented before Chen Fan's eyes like art.

These were things not found in image enhancement.

Image enhancement only clarifies facial features.

So, how do you judge someone by their back?

How do you judge someone who covers their face?

Or, if this person deliberately hunches their body, how do you judge that?

Machines are ultimately machines; people always have ways to overcome them.

Although most of the time, the machines win.

Chen Fan wasn't in a hurry. When Eagle Eye had finished, Chen Fan said, "Well, if I make this software later, will you be happy?"

"Happy? I'd be very happy. If you really make it, an accuracy rate of forty percent is enough. I don't expect you to make it too high."

"Well, I estimated that I could probably reach seventy or eighty percent, maybe even close to ninety. But that would require professional programmers. I only know a little bit of programming, not much."

"It's fine. Even fifty percent would make things much easier for everyone. I can't teach my skill to others; so many people have tried to learn, but they just can't remember it."

At this moment, the old man took the walkie-talkie and said, "Check that one on the west side, the one with the hat and glasses. Find out what's going on."

People went to investigate and found nothing wrong, so they let him go.

"See, I'm not really that good."

Just then, Eagle Eye finished speaking and pulled Chen Fan to his side. Zhang Tianxiong was quick-witted and stood in front, the two of them shielding Chen Fan in the middle.

A man pulling a suitcase walked into the high-speed rail station.

The man was calm, but Eagle Eye was not.

Eagle Eye gave a look to the people around him, and several of them approached.

They intended to detain the man.

But the man didn't give them a chance; he pulled his suitcase and ran, roaring, "There's a bomb in my suitcase! Get out of the way!"

The people around began to panic.

Chen Fan was speechless and muttered, "I feel like I'm possessed by Conan now."

"Take Chen Fan out first. Evacuate the crowd; don't cause a panic. It's going to be a busy day. I know this guy; he's a big lawyer."

???????

Zhang Tianxiong asked, "Then what was your reason for judging that this guy was suspicious?"

"A big lawyer is so rich, yet his suitcase is so shabby. Do you think that's right? And when have you ever seen a big lawyer travel with a suitcase? Also, when he lifted it just now, the suitcase clearly wobbled; it was a bit heavy inside."
