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

Chapter 41
How much is a human life worth?

The answer given by Li Bing was 50 yuan.

In the interrogation room, facing the ironclad evidence, Li Bing had completely collapsed.

"We made a deal, give her 50 yuan, she insists on [-]... I... I didn't mean to kill her... I didn't mean to..."

Ren Qiang has been a police officer for more than [-] years and has interrogated more prisoners than he has ever seen women.

The murderer was not interrogated by one or two people.

However, someone like Li Bing is really the first one.

Five hours ago, Huang Lan's clothes and a lot of blood were found in the No. [-] air-raid shelter on Jiguan Mountain.

The first crime scene where Huang Lan was killed was confirmed.

Lu Chuan immediately inspected the scene and found a large number of fingerprints, footprints, and murder weapons.

After comparison, Li Bing was determined to be the murderer.

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

Huang Lan went out every night and came back in the middle of the night, so she really had something to do.

According to Li Bing's account, he met Huang Lan on the way home on the evening of June [-]th, when he passed Tongguan Road, at the fork of Jiguan Mountain on Tongguan Road.

"The ones in the store are only 80 yuan, and the ones outside are all 50 yuan..."

Huang Lan did not do business in a house with a small red light, but solicited money on Tongguan Road by herself.

As for the location, it is in the woods of Jiguan Mountain.

However, the two had a dispute over the price.

Li Bing killed Huang Lan with the switchblade he carried with him.

"Tell me about your process of disposing of corpses and bones."

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

"For fear that someone would find out, I didn't dispose of the corpse at the beginning, I just went to have a look at it every few days."

"Then I found that the body had begun to decompose. When I went back half a month ago, I found only bones left."

"I was afraid that the bones would be discovered later, so I dismantled the skeleton in the air-raid shelter, and then took a little at a time to the feed factory, mixed it with the big bones and cut it, some were crushed into bone meal, and some...sold to hot pot restaurants..."

The entire process of Li Bing committing the crime has now closed the loop.

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

"Ding!"

"Advanced task completed: the host found the first scene of the skeleton case, completed the collection of criminal evidence, and assisted the skeleton case team to solve the case."

"Task Reward: Elementary Fingerprint Identification Analysis Skill Card."

"Does the host receive the reward?"

"receive!"

Fingerprint identification analysis is the most commonly used evidence analysis method in current criminal investigation methods.

The identification and analysis of fingerprints originated from abroad, and the theoretical knowledge of the formation of the system.

But in ancient times, the application of fingerprints has already begun.

The signature in the signature is the fingerprint rubbing for identity marking.

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

The reason why fingerprints become a tool for identifying identities is based on two principles: the shape of each person's fingerprints remains unchanged throughout life, and each person's fingerprints are different.

Just like there are no two identical anthurium palms in the world, some are pink and tender, some are brown, some are delicate and beautiful, some are dry and waterless, some have been touched by many people, and some are clean and lovely.

When Lu Chuan was in the Public Security University, he had learned relevant knowledge, and as an important skill in the current survey major, Lu Chuan was able to perform some simple fingerprint identification and analysis when he graduated.

However, compared with the basic fingerprint identification and analysis skills rewarded by the system, the identification knowledge that Lu Chuan has learned is a bit pitiful.

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

In relevant work specifications, fingerprint identification can be divided into several processes: preliminary inspection, separate inspection, comparative inspection and comprehensive evaluation.

By comparing the final appraisal to achieve the purpose of the same determination, so as to provide evidence for criminal proceedings.

The lines on the fingerprints are uneven, and the lines have starting points, ending points, and intersection points.

These feature points are the important features of comparing fingerprints.

In reality, it is difficult to collect fingerprints very comprehensively, that is to say, it is difficult to completely compare all the lines in the fingerprint for fingerprint comparison.

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

The technical term is similarity and difference assessment. In layman's terms, it means comparing whether the fingerprints are different or the same.

This requires determining fingerprint comparison feature points, such as the intersection of two fingerprint lines.

The two fingerprints select the intersection points at the same position for comparison. If there is a difference, there is no need to compare other feature points.

Because of this difference, it is enough to determine that the two fingerprints are not the fingerprints of the same person.

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

For example, the raised part of the fingerprint pattern is called the ridge, and the concave part is called the valley.

Crossing extensions between crests and crests will form terminations, bifurcations, divergences, isolations, loops and short lines.

The identification and analysis of fingerprints is to analyze the similarities and differences of fingerprints through these characteristic points.

The complicated knowledge and some special identification methods made Lu Chuan dizzy.

However, Lu Chuan's ability in fingerprinting has been greatly improved with the intermediate fingerprint collection skills and the primary fingerprint identification analysis.

Recently, the atmosphere of the Criminal Investigation Detachment has been relatively relaxed.

Although it took more than a week to solve the skeleton case, fortunately, the final result was very satisfactory.

As long as the murder case is solved, everyone will be good comrades.

In the next week, I will mainly fix the evidence and sort out the materials.

After the baptism of two murder cases in a short period of time recently, everyone has become more and more familiar with this set of procedures.

But familiarity is familiarity, and no one dares to make mistakes in the compilation of murder case materials.

Lu Chuan's life is somewhat moist.

Entering the end of September, it will be the National Day Holiday.

"Old Yang, where are you going to play on Eleventh?"

Holding the enamel jar, Lao Bai is already planning for a trip on the [-]th.

"Where can I go, my child will take the college entrance examination next year, and I will accompany him to do the questions."

Yang Sen's life is a little bit hard now, he revolves around his children every day.

However, in his words, in another eight months, he will have all his hardships, and he will be completely released.

"Where is Little Lu Eleven going?"

Lu Chuan had nothing to worry about. He was moving out the anthurium palms to bask in the sun, but the leaves were not green enough: "There is no arrangement. Maybe we should invite Dr. Shen for a meal."

The meal with Shen Yan started with human bone hot pot soup.

Now that the case is almost closed, that meal has to be made up.

Lao Bai nodded: "Xiao Shen is not bad. His parents both work in the Municipal Bureau and are also leaders. They can be regarded as a police family."

Lao Bai is a little envious of this, because his son did not choose the police academy in the college entrance examination.

However, sometimes Lao Bai is also a little lucky, fortunately his son did not become a policeman.

After all, the stakes are higher in policing than in most professions.

A man of Laobai's age is definitely a healthy policeman who has raised the average age of policemen.

boom.

While several people were talking, the office door was opened.
