Chapter 95 Advanced Skills
The system reward for Song Kun’s murder case has finally arrived.
What surprised Lu Chuan was that the system had a mode upgrade.
In the past, the mode where one could only passively accept system rewards has now become a mode where Lu Chuan can choose rewards independently.
The virtual picture in my mind also became vivid.
A window opens that can move up and down with Lu Chuan's thoughts.
"Criminal investigation technology: junior high school advanced criminal psychology, junior high school advanced investigation interrogation technology, junior high school advanced criminal imaging technology..."
"Security prevention technology: junior high school advanced network security technology, junior high school advanced Security engineering design, junior high school and senior security system maintenance..."
"Forensic identification technology: junior high and senior criminal photography, junior high and senior trace identification, junior high and senior document identification..."
In the entire list, All majors related to criminal investigation are covered.
Within each major, there are several or more than a dozen subdivided skills.
After a quick look, there are probably hundreds of skills.
Among all the skills, Lu Chuan’s existing skills are marked in red, optional skills are marked in blue, and non-optional advanced skills are marked in gray.
This system upgrade gave Lu Chuan the feeling of choosing his major again after the college entrance examination.
Under the teaching system of the Public Security University, the major classifications in the system are actually different school departments.
The skills inside are different professional directions.
In addition, there are branches of forensic science.
"Forensic clinical science: Junior high school and senior high school injury degree identification, junior high school and high school senior high school disability degree identification, etc."
"Forensic anthropology: Junior high school and high school senior skeletal identification and analysis, junior high school and senior high school skull facial reconstruction, etc. etc. ”
Also all branches of forensic psychiatry, forensic toxicology, forensic pathology, forensic entomology, etc.
In addition to these, there are many other kinds of skills.
For example, the ability to improve combat effectiveness such as shooting and fighting.
It is also divided into junior, middle and senior levels.
"Please host choose the type of reward."
"1. An intermediate skill card."
"2. An intermediate skill upgrade card."
Should you directly choose an intermediate reward, or upgrade an intermediate skill to a high level?
Lu Chuan didn't even think about it, he just didn't know how to do it.
After the system upgrade, the rewards provided are dazzling. Lu Chuan solves one case a day. It is estimated that it will be very difficult to learn them all in his lifetime.
Moreover, since Time Travel had the system, Lu Chuan has participated in the investigation of more than ten cases, large and small.
There were four or five murder cases, but the rewards obtained were all primary and intermediate skills.
It can be seen that it is relatively difficult to acquire advanced skills.
This time there was an opportunity to upgrade an intermediate skill to an advanced skill, and Lu Chuan would not miss it.
"System, select the intermediate skill improvement card."
"The intermediate skill improvement card has been selected, please host select the skills that need to be improved."
"1. Intermediate fingerprint collection skills, 2. Intermediate skeleton identification and analysis skills, 3. Intermediate fingerprint identification and analysis skills."
These are the three intermediate skills that Lu Chuan has mastered now. Lu Chuan can only learn from these three skills. Choose one to upgrade.
This time, Lu Chuan did not hesitate at all and directly clicked on the intermediate fingerprint identification analysis. "Upgrade your intermediate fingerprint identification and analysis skills...please wait."
Brush!
The system prompt tone fell, and the knowledge and skills about fingerprint identification and analysis flooded into the depths of Lu Chuan's mind like a tidal wave.
Intermediate fingerprint identification and analysis capabilities allowed Lu Chuan to make a major discovery in the case of the girl's human skin in Mai Langzhong.
The fingerprints collected from the skin of the deceased completely identified the suspect.
This time, the intermediate skill was upgraded to advanced, giving Lu Chuan a feeling of qualitative change.
The skills and methods of fingerprint identification and analysis were not hidden from Lu Chuan's eyes.
Fingerprint identification analysis is not only a systematic major, but also a major with huge differences in personality improvement.
Theoretical knowledge and practical experience are the keys to improving fingerprint identification and analysis capabilities.
The results analyzed by different fingerprint identification experts are also different.
The high-tech zone criminal police brigade, the fingerprint identification performed by front-line detectives should be the lowest level.
It can only be said that a rough identification and comparison of collected fingerprints with relatively clear and standardized shapes will be difficult to successfully identify and analyze fingerprints that are slightly deformed by pressure or are blurred or missing.
At the next higher level are people like Yang Sen and Lao Bai, who have some talents and relatively rich experience.
On-the-spot inspection and fingerprint inspection can carry out certain analysis and adjustment on some defective, deformed and blurred fingerprints, and then conduct identification.
The success rate is generally good, but for some fingerprints that are seriously missing, deformed, or blurry, you can only try your luck.
The ones at the higher level are people like Liu Guodong, who can barely participate in the fingerprint competition organized by the provincial department. Of course, he is at the bottom of the list. He can only win one or zero fingerprints at a time.
In Liu Guodong's own words, he enriched the expert pool.
There are more than a dozen criminal investigation detachments in the province, and each detachment must have one who can take it out.
Just like a novel website serving as a library, it may not work if you get in, but it will definitely not work if you can't get in.
If you are a more advanced fingerprint examiner, you can be called a fingerprint identification expert, at least in the province you can be called that.
For example, the Tianzhou City Criminal Investigation Detachment’s trace inspection is a professional job, not a part-time job. The job content is only one task, identification of fingerprints.
They are basically at the forefront in the entire province. In every fingerprint battle, there are at least two or three successful results.
There are also more advanced ones, namely several experts from the provincial department, who have the strength to participate in the national fingerprint competition organized by the ministries and commissions.
The combat effectiveness can be described as explosive.
As for the explosive method, Lu Chuan didn't know it before, but now he understands it after receiving the advanced fingerprint identification and analysis skills.
Usually, fingerprint identification analysis refers to the identity comparison of fingerprints.
Give you a fingerprint, perform corresponding preprocessing on the fingerprint, mark the feature points, calculate the data, and then compare it within the system.
The specific methods are various identification methods extended from the classification of ten-finger fingerprints, such as Qingdao-style single-finger fingerprint analysis and Chongqing-style single-finger fingerprint analysis.
Advanced fingerprint identification analysis includes not only single-finger fingerprint analysis methods, but also multiple-finger fingerprint analysis methods.
In addition to this, there is also some analysis of the owner himself through fingerprints.
For example, fingerprints can be used to determine the age, living habits, physical condition, living area and other information of the fingerprint owner.
These are things that Lu Chuan has only heard of before, but has never seen.
In advanced fingerprint identification analysis, these judgments and verification analyzes have detailed operation methods.
For example, when judging age, the palm area of a person is smaller when he is younger, and the fingerprint lines appear thinner.
By the thickness and density of the lines, you can tell whether the person is a child or an adult.
After data comparison, the approximate age range can be locked.
