Chapter 41: Fifty Yuan for a Life
How much is a life worth?
The answer given by Li Bing was fifty yuan.
In the interrogation room, faced with irrefutable evidence, Li Bing completely collapsed.
"We agreed to give her fifty yuan, but she insisted on eighty...I...I didn't mean to kill her...I didn't mean to..."
Ren Qiang has been a police officer for more than 20 years and has interrogated more prisoners than he has ever seen women.
A murderer is not interrogated by just one or two people.
However, people like Li Bing are really the first.
Five hours ago, Huang Lan’s clothes and a large amount of blood were found in the No. 3 air raid shelter in Jiguan Mountain.
The first crime scene where Huang Lan was killed was confirmed.
Lu Chuan immediately investigated the scene and found a large number of fingerprints, footprints, and the murder weapon.
After comparison, Li Bing was determined to be the murderer.
What shocked the investigators was Li Bing’s motive for murder.
Huang Lan goes out every night and doesn't come back until midnight. Something is indeed wrong.
According to Li Bing's account, he saw Huang Lan at the intersection of Jiguan Mountain on Tongguan Road when he was passing Tongguan Road on his way home on the evening of June 19.
"The ones in the store are only 80 yuan, and the ones outside are 50 yuan..."
Huang Lan did not do business in a house with a small red light, but recruited on Tongguan Road by herself .
As for the location, it is in the woods of Jiguan Mountain.
However, the two had a dispute because of the price.
Li Bing killed Huang Lan with the switchblade he carried.
"Tell me about your process of disposing of the body and bones."
"After I killed her, I left the body in the air raid shelter."
"I was afraid that someone would find out, so I didn't dispose of it at the beginning. I just went over to look at the corpse every few days. "Then I found that the corpse had begun to rot. When I went there again half a month ago, I found that there were 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 bit at a time to the feed factory, mixed it with the big bones, and cut it. Some were crushed into bone meal, and some... were sold to hot pot restaurants..."
The entire process of Li Bing's crime is now closed.
After the interrogation, Li Bing identified the scene and the case was considered solved.
“Ding!”
“Advanced mission completed: The host found the first crime scene of the skeleton case, completed the collection of criminal evidence, and assisted the skeleton task force to detect the case.”
"Task reward: Elementary fingerprint identification analysis skill card."
"Does the host receive the reward?"
"Receive it!"
Fingerprint identification analysis is the most commonly used evidence analysis method in current criminal investigation methods.
About fingerprint identification and analysis, it originated from abroad and systematically formed theoretical knowledge.
But in ancient times, the application of fingerprints had already begun.
The signature among the signatures is fingerprint rubbing to mark the identity.
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 everyone's fingerprints remains unchanged throughout life, and everyone's fingerprints are different.
Just like there are no two identical anthuriums in the world, some are pink, some are brown, some are delicate and beautiful, some are dry and dry, some have been touched by many people, and some have been touched by many people. clean and cute.
When Lu Chuan was at the Public Security University, he learned relevant knowledge, and as a relatively important skill in the field survey major, Lu Chuan was able to perform some simple fingerprint identification analysis when he graduated.
However, compared with the basic fingerprint identification and analysis skills rewarded by the system, the identification knowledge that Lu Chuan had learned was pitifully meager.
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 identification, the purpose of the same identification is achieved, thereby providing evidence for criminal proceedings.
The lines on fingerprints are uneven. The lines have starting points, ending points, and intersections.
These feature points are important features for fingerprint comparison.
In reality, it is difficult to collect fingerprints very comprehensively, that is to say, it is difficult for fingerprint comparison to completely match all the lines in the fingerprints.
So, the current fingerprint comparison methods can be divided into two major categories.
The professional term is called similarity and difference assessment. In layman's terms, it means comparing whether the fingerprints are the same or the same.
This requires determining the fingerprint comparison feature points, such as the intersection of two fingerprint lines.
The intersection points of the two fingerprints at the same position are selected for comparison. If there are differences, there is no need to compare other feature points.
Because of this difference, it is enough to determine that the two fingerprints are not those of the same person.
Of course, there are many professional terms in fingerprint comparison.
For example, the raised parts of fingerprint lines are called ridges, and the concave parts are called valleys.
The cross extension between ridges will form terminal points, bifurcation points, divergence points, isolated points, loop points and short lines.
Fingerprint identification analysis is to analyze the similarities and differences of fingerprints through these characteristic points.
The complicated knowledge and some special identification methods made Lu Chuan a little dizzy.
However, with intermediate fingerprint collection skills and primary fingerprint identification analysis, Lu Chuan's ability in fingerprints has been greatly improved.
Recently, the atmosphere in the Criminal Investigation Detachment has been relatively relaxed.
Although the investigation of the skeleton case took more than a week, fortunately, the final result was very satisfactory.
As long as the murder case is solved, then everyone will be a good comrade.
The next week will be mainly about fixing evidence and organizing materials.
After experiencing two murder cases in a short period of time recently, everyone has become more and more familiar with this set of procedures.
But we are familiar with each other, and no one dares to make mistakes in the collection of materials on the murder case.
Lu Chuan's life is somewhat nourishing.
It’s the end of September, and it’s the National Day holiday soon.
“Lao Yang, where are we going to play on National Day?”
Lao Bai was already planning the National Day trip with his enamel jar.
"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 bit hard now, and he revolves around his child every day.
However, in his words, in eight months, he will be free from all the hardships.
"Where are you going, Little Lu Eleven?"
Nothing has happened to Lu Chuan. He is moving out the anthuriums to bask in the sun, but the leaves are not green enough in the absence of light: "There are no arrangements, maybe I have to treat Doctor Shen to a meal.”
The meal with Shen Yan started with human bone hot pot soup.
Now that the case is almost over, that meal needs to be made up for.
Lao Bai nodded: "Xiao Shen is good. His parents both work in the city bureau and are also leaders. He comes from 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 a little lucky that his son did not become a police officer.
After all, the stakes are higher for the police than in most professions.
A man of Lao Bai's age is definitely a healthy policeman who will raise the average age of the police.
Bang.
While several people were talking, the office door was opened.
