Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 116 New Clues
Fingerprints are to trace inspection what old wine is to drunkards, and the top brand of a club is to old perverts.

We will never forget the fine wine we tasted, the bed sheets we rolled, and the fingerprints we saw.

In the dry mark inspection, whoever has no backlog and who has no fingerprints that failed the comparison.

When encountering a case, the fingerprint comparison can not be done for a while, and some tracers can't wait to carry it in their arms. When others swipe their mobile phones when they go to the bathroom, they swipe their fingerprints.

Each fingerprint, like an identity mark, has its own different characteristics.

Just like a person's figure, some fingerprint papillae are relatively flat, like an airport, and some are more majestic, like undulating mountain peaks.

Some fingerprint ridges are soft and thin, like the waist of a willow leaf, while others are thick and thick, like a bucket.

In the eyes of ordinary people, fingerprints are messy thick lines, but in the eyes of trace inspection, every fingerprint that has been researched and played has its own life.

In front of the dissecting table, Lu Chuan changed his position and carefully observed the half fingerprint extracted from the tape marks on the deceased's ankle.

"Have you found anything?"

Shen Yan was also very happy that Lu Chuan could find this fingerprint. Forensic doctors actually don't study this much when doing autopsies.

Whether it is forensic pathology or forensic anthropology, it is either the study of how the corpse died or who the corpse was, but it all starts with the corpse itself.

To extract the fingerprints on the corpse, to be honest, this is a bit of a compound talent.

Ordinary forensic doctors can't do it, and neither can ordinary trace inspection.

"I feel that this fingerprint is a bit familiar... but I can't remember where I saw it. I will go back to the office and look in the system after I finish it."

The fingerprints made by Lu Chuan have been compared in the system, and there are records of success or failure.

Just call out these fingerprints and compare them, and you should be able to find them.

"Let's do trace evidence collection first, and then send it to the provincial department."

This time, the progress of the micro-evidence inspection was relatively fast, and the results found were similar to the last corpse.

In addition to the physical evidence collected from hidden parts such as nails and mouth, similar hair was also found on the second corpse.

"This should be the hair of an animal. It is more likely to be a dog or a cat, but of course it is not necessarily a dog or a cat."

Lu Chuan agreed with Shen Yan's judgment: "There are such hairs in many parts of the two corpses, which means that the deceased should have been able to touch this kind of hair frequently during their lifetime."

"Is it possible that when the murderer threw the body away, what remained of the body wrapped?"

"It's also possible. The murderer couldn't just throw the body naked. He should have covered it with something. But the specific situation depends on the test results."

There are obviously many possibilities for the hair guess.

But no matter which one, you need to wait for the test results to come out.

"You rest first. You just finished dissecting the corpse and helping me with the micro-evidence test. I will hand in the things first and then look at the fingerprints."

Beside the dissecting table, the two tossed back and forth several times, and Shen Yan's physical exertion was indeed a lot.

Beads of sweat had soaked on his forehead, clinging to a few strands of hair.

"Okay, then you go to work, I will go back to the office to rest for a while."

The two separated, and Lu Chuan quickly returned to the current survey office.

"Master, this is the trace evidence collected from the second corpse."

After handing over the evidence box to Liu Guodong, Lu Chuan immediately sat in front of the computer and tapped on the keyboard.

Liu Guodong, who was just about to deliver physical evidence, looked at the busy Lu Chuan: "Let's take a break first, this case is not making much progress now, and it is probably going to be a protracted battle again."

Lu Chuan shook his head: "No, master. When I was collecting trace evidence, I found that the corpse's wrists and ankles also had traces of adhesive tape left behind."

Liu Guodong nodded. The colloids on these traces have been collected. After analysis, it is of some value to be able to determine what tape the murderer used.

"In addition to these, half a fingerprint was also found on the glue mark on the left ankle of the corpse."

Ok?
"Half a fingerprint?"

Lu Chuan's words surprised Liu Guodong a lot. Fingerprints were found on the body, so it is very likely that they were left by the murderer.

Yang Sen and Lao Bai also surrounded him: "Fingerprints were found on the corpse?"

"This is a big discovery. It is very likely that it was left by the murderer."

While operating the computer, Lu Chuan retrieved the fingerprints that he had seen before, while talking: "The fingerprints were found on the tape tie mark on the inside of the left ankle of the corpse."

"It is very likely that it was left when the murderer removed the tape."

"And this half of the fingerprint feels a little familiar to me, I always feel like I've seen it somewhere..."

Snapped!
The sound of Lu Chuan typing on the keyboard stopped, and the screen displayed the fingerprint identification analysis records that Lu Chuan had done half a month ago.

A slightly distorted, but very clear fingerprint appeared on the screen.

"This is it!"

Half a month ago, when investigating the murder of Song Kun, Lu Chuan took a break from his busy schedule to conduct an identification analysis on the fingerprints submitted by the police station and criminal police brigade below.

At that time, there were twelve sets of fingerprints in total, nine sets were successfully identified, and there were three more sets, because there were no matching objects in the system, and the identification was not successful.

After that, the matter of these three sets of fingerprints was put aside, but Lu Chuan had handled these fingerprints meticulously after all.

It's been a while, so I'm still impressed.

"This is it!"

Lu Chuan pointed to one of the three groups of fingerprints that had not been successfully identified: "This is the fingerprint!"

"Match it and see if it works!"

Liu Guodong's tone was very excited, this is definitely the key clue.

Although the fingerprint itself has not been compared successfully, the case involved in this fingerprint can be retrieved.

At that time, if you follow the vines, you may find new discoveries.

While Liu Guodong was speaking, Lu Chuan had already preprocessed the fingerprints collected on the corpse.

It's one thing to look familiar by yourself, but it's another thing to compare it in the system.

There are only half of the fingerprints on the corpse, and there are many ridge line segments. In fact, the identification and analysis of this fingerprint is still very difficult.

At least, with the strength of Liu Guodong, Yang Sen and Lao Bai, it is estimated that they can't handle it.

But in the face of Lu Chuan's advanced fingerprint identification and analysis skills, this somewhat fuzzy half fingerprint looks like a dancer without clothes.

She was naked in front of her eyes, without any secrets.

In less than ten minutes, the feature points are marked and the relevant data is calculated.

Ding!
The system immediately issued the familiar sound of complete matching success.

"It's done!"

"It really did!"

Yang Sen and Lao Bai shouted excitedly.

Liu Guodong was still holding the trace evidence box that Lu Chuan gave him, looked at the successful comparison report on the computer screen, and opened his mouth: "I'll go to report the good news to Team Qin, Xiao Lu, you've done a good job again this time!"
