How much is a human life worth?

The answer Li Bing gave was fifty yuan.

In the interrogation room, faced with ironclad evidence, Li Bing had completely broken down.

"We agreed to pay her fifty yuan, but she insisted on eighty... I... I didn't mean to kill her... It wasn't intentional..."

Ren Qiang has been an officer for over twenty years, interrogating more criminals than he has seen women.

Murderers, he's interrogated more than a few.

However, someone like Li Bing is indeed a first.

Five hours ago, inside Air Raid Shelter No. 3 on Cock's Comb Mountain, Huang Lan's clothes and a large amount of blood were discovered.

It confirmed the first crime scene of Huang Lan's murder.

Lu Chuan immediately investigated the scene, discovering numerous fingerprints, footprints, and the murder weapon.

After comparison, Li Bing was identified as the murderer.

What shocked the investigators was Li Bing's motive for murder.

Huang Lan went out every night, returning only at midnight, clearly for business.

According to Li Bing's confession, he saw Huang Lan on Tongguan Road at the junction with Cock's Comb Mountain on his way home on the night of June 19th.

"In the store it's eighty yuan, but outside it's only fifty..."

Huang Lan was not conducting business in a house with red lights but was soliciting herself on Tongguan Road.

As for the location, it was in the woods on Cock's Comb Mountain.

However, the two argued over the price.

Li Bing used a spring knife he carried to kill Huang Lan.

"Tell us about how you handled the body and bones."

"After I killed her, I left the body in the air raid shelter."

"Afraid someone would find it, I initially didn't deal with the body, just checked on it every few days."

"Then I found the body had started to decompose, and when I went back half a month ago, there were only bones left."

"Afraid the bones would later be discovered, I dismantled the skeleton in the shelter, then each time took a bit to the feed factory, mixed it with large bones for cutting, some ground into bone meal, some... sold to hotpot restaurants…"

Li Bing's entire crime process thus came full circle.

After the interrogation ended, Li Bing identified the scene, and the case was deemed solved.

"Ding!"

"Advanced task completed: The host found the first crime scene of the skeleton case, completed crime evidence collection, assisting the skeleton task force in solving the case."

"Task reward: Basic Fingerprint Identification Analysis Skill Card."

"Does the host wish to claim the reward?"

"Claim!"

Fingerprint identification analysis is currently one of the most commonly used evidence analysis methods in criminal investigation.

Fingerprint identification analysis originated abroad and systematically formed theoretical knowledge.

However, the application of fingerprints has long since begun in ancient times.

The fingerprint print in signing and stamping was used for identity marking.

For hundreds to thousands of years, fingerprints have been widely used as an effective tool for identity recognition.

Fingerprints become an identity recognition tool based on two principles: everyone's fingerprint shape remains unchanged for life, and everyone's fingerprints are unique.

It's like there are no two identical flamingo-lilies in the world, some are pink, some are brown, some are vibrant, some are withered and dry, some are touched by many, some are cleanly beautiful.

When Lu Chuan was at the Public Security University, he studied related knowledge, and as an important skill in crime scene investigation, by graduation, he could conduct simple fingerprint identification analysis.

However, compared to the system's reward of basic fingerprint identification analysis skills, the identification knowledge Lu Chuan once learned seems rather meager.

After years of development, fingerprint identification in criminal investigation has formed a standard working procedure.

In relevant work specifications, fingerprint identification can be divided into preparatory examination, separate examination, comparative examination, and comprehensive judgment processes.

Through final comparative identification to achieve the purpose of unified credence, thus providing evidence for criminal proceedings.

Fingerprint patterns are uneven, with starting points, endpoints, and crossing points.

These feature points are important characteristics for fingerprint comparison.

In reality, fingerprint collection is difficult to be very comprehensive, that is to say, fingerprint comparison is very hard to completely match all the patterns in fingerprints.

So, the current fingerprint comparison methods can be divided into two major categories.

The professional term is called similarity and difference evaluation, commonly speaking it is comparing whether fingerprints are the same or different.

This requires determining fingerprint comparison feature points, such as the crossing points of two fingerprints.

Select the same position's crossing point for two fingerprints for comparison, if there is a discrepancy, then you don't need to compare other feature points.

Because this one discrepancy is enough to determine that the two fingerprints are not from the same person.

Of course, there are many professional terms in fingerprint comparison.

For example, the protruding part of the fingerprint pattern is called the ridge, the recessed part is called the valley.

Between ridges, crossing, and extending can form endpoints, bifurcation points, divergence points, isolated points, loop points, and short patterns.

Fingerprint identification analysis is analyzing the similarities and differences of fingerprints through these feature points.

Complex knowledge and some special identification methods make Lu Chuan somewhat dizzy.

However, with intermediate fingerprint collection skills and basic fingerprint identification analysis, Lu Chuan's abilities in fingerprints have greatly improved.

Recently, the atmosphere at the Criminal Investigation Team is rather relaxed.

The skeleton case investigation, although took more than a week, fortunately, the final result was very satisfactory.

In murder cases, as long as they're solved, everyone's a good comrade.

The following week mainly involves solidifying evidence and organizing materials.

After being baptized by two murder cases in a short duration, everyone is becoming increasingly familiar with these processes.

But familiarity is one thing, no one dares to have any slip-ups in organizing murder case materials.

Lu Chuan is living somewhat comfortably.

Entering late September, the National Day holiday is about to come.

"Old Yang, where are you going for the National Day?"

Old Bai, holding an enamel mug, is already planning his National Day outing.

"Where can I go? The kid has the college entrance exams next year, I'll be staying with him doing exercises."

Yang Sen's life is rather tough right now, always revolving around the child.

However, as he says, in eight months' time, he'll be free, completely liberated.

"Lu, where are you going for the National Day?"

Since there's nothing much on his plate, Lu Chuan is moving the flamingo-lily out to get some sun, the leaves aren't green enough without proper lighting: "No plans, maybe I'll have to treat Forensic Doctor Shen to a meal."

The meal with Shen Yan began with the human bone hotpot soup.

Now that the case is about done, that meal has to be made up.

Old Bai nodded: "Shen is good, his parents both work at the municipal bureau, they're leaders as well, considered a policial family."

Old Bai somewhat envied this, because his son didn't choose police school for college exams back then.

However, sometimes Old Bai is somewhat relieved, luckily the son didn't become a police officer.

After all, compared to most industries, the risks for police are higher.

Like someone of Old Bai's age, he is certainly raising the average age of healthy police officers.

Bang.

As they were speaking, the office door was opened.
