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

Chapter 96 Participating in the Task Force

A small fingerprint can reveal all kinds of information.

In addition to age, through fingerprints, it is also possible to determine whether the other party smokes, whether he has recently taken medicine or drinking alcohol, and even what cosmetics the other party uses can be answered through fingerprint identification analysis.

Because fingerprints are composed of sweat and oil secreted by sweat glands and sebaceous glands on the fingers.

Among these ingredients, 98% is water, in addition to amino acids, iron, magnesium, zinc, urea and other trace elements.

It is these subtle components that can reveal relevant information about different individuals.

Because people with different living habits, the chemical substances contained in sweat and oil are slightly different.

For example, people with heavy taste usually eat more salt, and the sodium ion content in fingerprint residues will be high.

Of course, since the fingerprint itself is relatively small, the amount of residual substances is calculated in milligrams and micrograms.

For the identification and analysis of fingerprint residual substances, general instruments are not enough.

This involves another skill, trace evidence analysis.

In reality, any contact between objects will cause changes in trace substances.

The changed trace substances can indicate the occurrence or non-occurrence of a certain fact or link the objects in contact.

Through the identification of trace physical evidence, its source can be determined, the process of committing the crime and the characteristics of the criminal can be revealed, thereby providing evidence for the investigation and solution of the case.

Although Lu Chuan did not have the skills in this area, part of the knowledge in this area was included in the advanced fingerprint analysis.

In Lu Chuan's view, advanced skills are no longer a single skill, but a collection of multiple skills.

For example, in image processing technology and advanced fingerprint identification analysis, the preprocessing methods for fingerprints are more abundant.

Which involves how to use drawing software to process fingerprints.

This involves a series of image processing skills such as image transformation, decoding compression, enhancement and restoration.

Although the skill rewarded by the system is advanced fingerprint identification and analysis, after Lu Chuan has mastered it, he can also use other abilities involved in it independently.

The morning of November 21.

The warm sun in winter is like a girl's bare hands. It is neither hot nor hot when touched on the body, but also has a feeling.

The case of Song Kun's murder is said to have been handed over to the provincial department.

Experts were sent from above, and a special case team was reorganized, and elite soldiers and generals were mobilized from various departments such as economic investigation, criminal investigation, and technical appraisal center.

Even, Lu Chuan heard from Lao Bai that the task force invited experts from the Provincial People's Hospital as consultants.

The anthurium, which has not been tended for several days, is slightly dull in color.

Lu Chuan is carefully building, fertilizing and watering, moving to the window sill to bask in the warm sunshine.

Lao Bai held the enamel jar and hummed excerpts from Peking Opera that Lu Chuan had never heard before.

As usual, Yang Sen was skewering, and the small-leaf red sandalwood worth 28 yuan already had the meaning of small-leaf red sandalwood.

The currently surveyed pig hair brush has made great contributions.

However, the wear and tear of the brush is a bit serious. The originally dense and hard hair is now a little curly, and there is even a spot in the middle.

"Lao Yang, this brush is public property, and I will accompany it when it is worn out."

The pig hair brush may not have thought that besides being able to have close contact with the bones, there are other uses in his life.

This is true for brushes, let alone people.

Therefore, no one should ever underestimate their abilities.

Just like the Dongguan-style service moved from Simmons to the live broadcast room, the value created is higher.

There are more people who appreciate beauty, and it is the right of all men to accept the influence of art.

Ring Ring Ring!
In the present office, there is only one landline, which is on Liu Guodong's desk.

When it sounds, it means work is coming.

Sure enough, Liu Guodong who put down the phone after a while looked at Lu Chuan: "Xiao Lu, come with me to Team Qin's office."

"Qin team is back?"

Qin Yong went to the city bureau early in the morning to participate in the preparatory meeting of the task force, and he came back so soon?
After putting down the anthurium and stroking it lightly, Lu Chuan put on his police uniform jacket and followed Liu Guodong to leave.

In other words, during this period of time, Qin Yong's visits and condolences are obviously not as many as before.

Most of the time, Lu Chuan was called to the office.

Everyone had a good night's sleep last night.

Song Kun was killed, and one of the murderers has been arrested. Wang Manli's boyfriend is not currently in Haizhou City, but the exact location is also known.

According to yesterday's plan, the arrest operation will be implemented today.

"Xiao Lu, prepare yourself. For the next period of time, you will follow me and participate in the investigation of subsequent cases as a member of the special case team."

Lu Chuan was taken aback for a moment, he didn't expect Qin Yong to call him over, he was talking about joining the task force.

Liu Guodong's face was filled with joy, which was a good thing for Lu Chuan.

"Is there any problem with the survey office?"

"No, no, Team Qin can rest assured that Lu will be able to cooperate with the task force."

Qin Yong nodded. Liu Guodong's statement made him very comfortable. Leaders often need such subordinates.

He can understand when you are really asking for opinions and when you are going through the process.

"Follow me to the Municipal Bureau in the afternoon, and the experts from the Provincial Department will arrive in the afternoon."

"Yes!"

"Ding!"

"Advanced task: Participate in the special case team of the provincial department, assist Li Donglin of the second criminal investigation department of the provincial department, collect clues, and provide technical support for solving the case."

Surveying the office now.

"This is a good thing!"

Lao Bai put down the enamel jar and was very happy to know that Lu Chuan was about to join the task force.

Yang Sen also put down the pig hair brush, and held the small leaf red sandalwood in his hand: "It's a good thing to know the experts from the provincial department and have a qualification."

The task force depends on the level of the task force and the cases involved.

Generally speaking, as long as there is a murder case, a special task force for the murder case will be established.

Level... There is no level. The task force established by the criminal investigation detachment is to solve the case.

Of course, it doesn't mean that the case will be solved after the establishment of a task force.

Therefore, the special case team also meant to assign a case to a certain criminal policeman.

For unsolved cases, the detachment will designate one or two criminal police officers to focus on the case.

This is the origin of the daily work of the first-line criminal investigation. As long as there is no new case, the work of the previous case must be done.

Many criminal policemen, even their whole lives, carry several unsolved cases on their shoulders.

Ten or 20 years, as long as he has not retired, he always wants to solve this case.

Gradually, it became a heart disease.

There are very few front-line criminal policemen who do not have a backlog of cases when they retire.

Of course, some people can't survive retirement, such as Song Kun.

Song Kun is one of the rare people who didn't have an accumulated case during his lifetime, but he died in a common disappearance case when he was about to retire.

One level higher than the task force established by the Criminal Investigation Detachment is the task force established by the Municipal Bureau.

This type of task force, whether it is a murder case, a robbery case, or other cases, will have a lot of influence.

In most cases, there will also be cooperation between different types of police.

But a task force of this level has influence in the city bureau.

The task force formed by the provincial department is different.

There are not many cases where the provinces and departments set up a task force, but if there is one, it is a major case.

Under normal circumstances, no arrogant suspect with two or three lives in hand is not qualified.

Even if Song Kun was murdered by a criminal policeman, he would not be able to reach this level.

But the case behind Song Kun's murder deserves enough attention from the provincial government.

Because of Wang Manli's preliminary account, there are already four people missing from her hands.

Three years, four people.
