Chapter 237

The man wore a police uniform; the medals on his chest and the stars on his shoulders told others that his status was not low.

The man was quite old; he looked very slowly, comparing them one by one, and said, "Eh, this is wrong, this one doesn't match up; I think these two do match up."

The man pointed to two fingerprints.

Chen Fan nodded, then looked at Old Song; Old Song immediately made a phone call to someone.

"People from Liaoyuan, this is Old Song. By the way, the fingerprint comparison results are out: one arson case, one robbery case; the two cases can be merged. You can start making arrests."

"Damn, really? Then that's right. By the way, who is the person being compared?"

"A guy in the fingerprint database; I'll send you the photo later."

"Awesome; I'll treat you to a meal later."

Everyone below the stage stared with mouths agape.

Wait, just now, didn't we all solve a case?

So fast?

The crowd turned their gaze toward the police officer on stage; the officer habitually reached for a cigarette, but remembering it was a class, he didn't take one.

"Mm, barring any surprises, the match is indeed confirmed; young people's minds are truly agile, far superior to ours."

Chen Fan said, "Mm, if it were me, I wouldn't handle the fingerprints this way."

Everyone looked at Chen Fan.

Chen Fan put on gloves and said, "Look, if I start committing crimes while wearing gloves, it becomes basically impossible to process; so what would you do?"

The old police officer on this side said, "Are you giving me a difficult problem?"

"Yes."

"Hold this paper."

Chen Fan held it; the police officer on this side said, "Did you leave any traces?"

"I left some, but your point doesn't count as a reason."

The old officer said, "I don't need this as evidence; I only need to know the general direction of the grip force. Generally, fingerprints can infer a person's height; similarly, the palm can too."

In that instant, everyone's hair literally stood on end.

Holy crap, holy crap, is it really that awesome?

Chen Fan said, "This isn't elegant; it's completely boring. This is just deduction, isn't it?"

The old police officer said, "Yes, it is deduction. That's how I reason it out; my own research direction actually has some error. Human palms, in fact, like feet, have certain margins of error."

"Palm prints can actually be calculated into this as well. However, I know how to solve your problem; I'll give you some data later, and you'll understand."

"Data? Oh, I know; it's the secrets leaked by that bunch of trash software before, right?"

"Yes; I retrieved it from this side. Many people didn't use it, but I found it and brought it out for use."

The old police officer said, "Give me a copy of the data later; I'll ponder it then. If I'm lucky, it might really be used to lock onto a person."

"Yes; many people have the habit of going to the scene to see their own masterpieces."

At this moment, the crowd below the stage was already extremely excited.

Chen Fan pointed to a pile of fingerprints and said, "I've given you all the methods; you go ahead."

Everyone went up to the stage one after another, comparing fingerprints; for those that matched, Old Song immediately made a phone call; for those that didn't match, there was no worry, no matter.

There was nothing shameful about this; it was just that the case was solved this way, which was truly joyful.

Soon, the break time arrived; Chen Fan followed several officers outside, where everyone stood in the corridor, puffing away.

"Awesome, truly awesome. Old Song, you really hit the jackpot. Honestly, if Chen Fan were on our side, whenever an accumulated case appeared, I'd cut off my own head."

Chen Fan took the cigarette but didn't speak.

Old Song said, "Do you have a daughter?"

"I do, but she's married, hahaha."

Chen Fan chuckled and said, "Then forget it; I won't go. You don't have a daughter either, so I won't go."

"The Misses at my workplace are good-looking."

Chen Fan got interested and said, "Then we must contact each other more often in the future; we'll keep in touch."

Hahaha; the several officers present all laughed and gave Chen Fan a thumbs-up. Honestly, Chen Fan's performance was truly excellent.

Moreover, he wasn't pretentious; he said whatever came to mind, and his personality was very good. Everyone naturally felt willing to get along with Chen Fan.

Qin Ming said in the observation room, "You might not know this group of people? The one who gave Chen Fan a cigarette."

Everyone nodded.

"That is the Chief; his rank isn't the highest. He became Chief because, in earlier years, he risked his life with someone and injured his leg. Back then, chasing drug traffickers and such, this Chief was ruthless; cracking down on drugs was absolutely a matter of going all out."

"And that very thin person over there? Let me tell you, that guy was once a martial arts champion; his skills were extraordinary."

"By the way, there's also that person; back then, to catch someone, he took a few people and directly staked out that guy for a month, forcing him out. Eating, drinking, and sleeping were all done inside the car."

"And that person over there, the one with the mosaic; he was previously an undercover agent. I won't go into details on this one."

Everyone understood well: when an officer's face appeared with a mosaic, it meant that person's identity was highly concealed.

Protection needed to be provided.

Teacher He said, "Are Chen Fan's methods really effective?"

"Effective; it improves efficiency. Just like often, the criminals are right at the scene; we can quickly lock onto a general location and directly apprehend the person right there on the spot."

Damn, it's truly chilling.

This speed, this efficiency.

The audience is also the most afraid, because this truly serves as a deterrent.

Regarding crime, you must think about the capabilities of domestic forensic experts here; if you have no way to deal with this group of people, then do not commit crimes.

Returning to the room, Chen Fan took out some photos or some videos and said, "I'm giving you some things now; it's my intuition. Let me put it this way: you all know I have imagined countless crimes in my mind."

Everyone nodded in agreement.

Chen Fan said, "These videos and photos were all taken casually by me. I'm showing them to everyone to ask: if you were to commit a crime, or if a criminal were to commit one, which location would be suitable for dumping a body?"

Everyone looked at Chen Fan; this topic was indeed quite fresh.

Someone said, "In the first photo, the area under that tree over there—I think it's the most suitable for a crime. Under the tree, there would be less rain."

Chen Fan shook his head and said, "Wrong. I wouldn't choose under the tree because it's hard to dig."

The police officer nodded, as if that was indeed correct.

"Then how about this side, by the river?"

"No good. The water would wash the body out."

"This side, over here in the grass."

"No good. If the grass is disturbed, it's easy to be discovered; this area shows signs of having been tampered with."

I thought, "Damn it."

"So it's the open ground?"

Chen Fan said, "Eighty percent of the time, one would choose open ground, because such an area is most suitable. Secondly, if it's a long-term case, it falls outside the scope of consideration. However, it can still be distinguished. For instance, if the trees around are growing well, but the grass and plants here are relatively short—in the wild, no one trims them—then what does it mean if they are growing relatively short?"

Everyone instantly froze.

Several big shots in the front row stood up directly; one said, "Wait a moment, I'll make a phone call here."

The big shot went out to make the call. After finishing, he returned and handed Chen Fan a cigarette; at this point, who still cared whether it was class time?

The big shot paced back and forth, anxiously tapping the table, his heart filled with restlessness.

Soon the phone rang, and the man said, "Found it."

"Is it inside?"

"Yes, it's inside. They've dug it up here. There are bones underneath; it's that person. The ring matches; the gold ring is still on."

"Has the person been caught?"

"Yes."

Here, the man directly saluted Chen Fan and said, "Thank you."

Afterwards, everyone stood up one by one, and the group saluted Chen Fan.

Chen Fan returned the salute and said, "It's a small matter. I was just thinking from the perspective of crime; if I were to commit a crime, I would do it even more perfectly than this bunch of trash."

Someone joked, "Does a perfect crime exist?"

"It doesn't exist. Any exchange of matter always follows principles. As long as you commit a crime, evidence will be left behind. Not finding it doesn't mean there isn't any; it just means we haven't discovered it yet."

Everyone nodded in agreement.

Everyone signaled Chen Fan to continue.
