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

Chapter 88

The two walked side by side, Lu Chuan kept frowning tightly, and looked back from time to time to see the Qingsong Medical Examination Center, which was getting further and further away, already hidden in the cold wind.

About tens of meters away, Lu Chuan stopped.

"Master, something is wrong, this woman...I still feel something is wrong."

This time, Liu Guodong looked at Lu Chuan seriously.

As a criminal policeman, intuition has never been the standard for handling cases, let alone the basis for conviction.

However, the intuition of the criminal police is different from that of ordinary people. They have dealt with various criminals all year round, and they seem to have a vigilance of crimes accumulated through experience.

Although Lu Chuan has not been in the police force for a long time, he has been engaged in spot investigation and trace inspection work for a long time, and has little front-line experience, but he has been involved in many cases.

In the past six months, the criminal investigation detachment's homicide detection rate has been [-]%, and Lu Chuan has contributed a lot.

Having this intuition, or experience, makes sense.

not to mention……

Liu Guodong, Lu Chuan, and Zhang Hui had already made an appointment, and they would call Zhang Hui as soon as the investigation of the two people here was over.

But the two of them came out of the Qingsong Medical Examination Center for more than ten minutes, and neither of them took the initiative to call Zhang Hui.

Lu Chuan felt that there was something wrong with this woman, so why didn't Liu Guodong murmur in his heart.

However, the two people's questioning of Wang Manli just now was relatively thorough.

In the process of talking to her, Wang Manli did not show any abnormalities
The contact with Goldman Sachs is evidenced by WeChat chat records, and the fingerprints on the electric car are also proved by surveillance video.

Perfectly cleared Wang Manli's suspicion in the Goldman Sachs disappearance case.

It's like...the answer has been prepared in advance for the arrival of Liu Guodong and Lu Chuan.

"Xiao Lu, can you tell me the reason?"

Lu Chuan's frown deepened: "I asked for leave last night to attend my cousin's engagement banquet, and saw this woman in the parking garage of Haizhou International Hotel."

"Have you seen her?"

Liu Guodong was slightly surprised: "Didn't she recognize you just now?"

"It's just that we met once in the elevator. She probably doesn't remember it." Lu Chuan shook his head: "At that time, I felt that this woman was a little familiar, and I always felt like I had seen it somewhere before."

"Today... this feeling is even stronger."

"Check it out?"

Lu Chuan nodded: "Well, check it out, this Wang Manli drove a silver-gray BMW sedan yesterday."

"A nurse in the medical examination center, so rich?"

"Also, she went to the seventh floor of Haizhou International Hotel yesterday, which is the room department."

"It took me just over two hours to attend the engagement banquet. When I was driving back to the underground garage, I noticed that Wang Manli's car had already left."

The meaning of Lu Chuan's words is very clear.

Since Wang Manli is working locally in Haizhou, it is unlikely that she will stay in a hotel at night.

Even if you stay in a hotel, you won't just stay for two hours.

So, what did she do at Haizhou International Hotel yesterday?
Liu Guodong nodded: "I asked my friend from the economic investigation to help me check Wang Manli's assets and bank statement."

To check the economic details, the economic investigation is much more professional and convenient than the criminal investigation.

Of course, it doesn't mean that criminal investigations cannot be investigated, but there are more procedures to go through.

For example, only by writing an official letter to the bank can you inquire about the specific information of the depositor.

However, due to the special nature of the work, the economic investigation side has super authority.

The economic situation of ordinary people is transparent to them.

As for whether there is anyone to help, that is even more trivial.

The fingerprint identification that Lu Chuan did for them last time helped them a lot.

I bought all the 40 instruments, so this trivial matter is naturally out of the question.

Since the two of them had decided to investigate Wang Manli, there was no need for the cold wind to blow.

He called Zhang Hui, who was still busy there, so Lu Chuan directly paid for a taxi back to the Criminal Investigation Detachment.

Yang Sen and Lao Bai hadn't come back yet, so Liu Guodong contacted his friends from the economic investigation.

But Lu Chuan has nothing to do now.

In the building of the Criminal Investigation Detachment, it was rare that it was a little deserted. Many internal staff members were taken to the scene, and there were only two or three big cats and kittens left in the building.

Lu Chuan, who was fine, began to scan his fingerprints.

During this period of time, because all the energy of Xiankan's side was devoted to the case of Song Kun's murder, some normal work was delayed.

A lot of work has been accumulated, and there are more than a dozen cases that require fingerprint identification and analysis alone.

Taking advantage of this gap, Lu Chuan happened to clean up some work at hand.

In the past week, there have been a total of twelve fingerprint identification and analysis cases.

There were four robberies, three burglaries, and some previous backlogs. Recently, new discoveries were made, and there were also fingerprints that needed to be compared.

Lu Chuan, who has mastered intermediate fingerprint identification and analysis skills, can be described as handy most of the time when dealing with these relatively simple cases.

Although the quality of the fingerprints collected by the police station and criminal police brigade below is average, they can basically be matched successfully after Lu Chuan's preprocessing.

It is rare that there is no matching fingerprint, and it is also because there is a high probability that there is no fingerprint of the target person in the fingerprint database itself.

It's hard for a clever woman to cook without rice. This is something that even gods can't help.

For the identification and analysis of fingerprints, at present, there is actually no particularly fixed, systematic, and unified procedure.

In the earliest days, ministries and commissions and major provinces and departments established corresponding fingerprint identification agencies in order to play the role of fingerprint identification in solving cases.

And the standard unified ten-fingerprint classification, which is the basis of all current fingerprint identification analysis.

However, in the investigation of specific cases, the disadvantages of the ten-fingerprint classification being too simple and rough gradually emerged.

On this basis, various localities have developed technology, integrated classification, and formed some unique fingerprint analysis methods.

So far, fingerprint identification and analysis can be roughly divided into two categories: single-fingerprint analysis and joint-fingerprint analysis.

Among them, single-fingerprint analysis is the most widely used.

Among all the single-fingerprint analysis methods, the Qingdao-style single-fingerprint analysis method and the CQ city single-fingerprint analysis method are the most famous.

It is also a template analysis method for teaching skills in universities.

These two methods have their own advantages and disadvantages.

Among them, the Qingdao-style single-fingerprint analysis method divides the two basic types of fingerprint skips into 28 major categories and 68 sub-categories.

The analysis is carried out with the aid of specially defined "analysis rules".

The so-called "analysis gauge" is engraved with a circle with a diameter of 80 mm, called the analysis circle, and engraved with two straight lines intersecting to form an [-]-degree angle called the gauge angle.

Use the "analysis rule" to delineate the fingerprint, mark the feature points, and then perform data calculation and analysis.

In the Chongqing-style single-finger fingerprint analysis method, fingerprints are divided into three major categories: bow, skip, and bucket, and 3 subcategories, and the analysis method is embodied by pictographic symbols.

For example, in the analysis of the bucket pattern, this type of fingerprint is composed of lines such as rings, spirals, and curved lines, and is divided into 11 categories according to the structure and shape of the central lines.

The diameter of the central circular line is not more than 4 mm, which is called a circular ring and is represented by the symbol "0".

The central circular line with a diameter of more than 4 mm is called a long line ring, which is represented by the symbol "①".

The center has one or more spiral lines that rotate one circle clockwise, and the diameter of both ends does not exceed 4 mm. It is called a circular clockwise spiral and is represented by the symbol "9".

Lu Chuan's intermediate fingerprint identification and analysis skills are a combination of these two single-fingerprint analysis methods.

Therefore, most of the requests for fingerprint identification reported by grassroots police stations and criminal police brigades are not a problem for Lu Chuan.

Except for a few exceptions, the clarity of the fingerprint itself is too rubbish, and it looks like a mass of paste. It will take Lu Chuan a very long time and a lot of energy to get it done. Other fingerprint comparisons can be done in as fast as ten minutes. It's almost half an hour slow.

Near the evening, when Yang Sen and Lao Bai came back, Lu Chuan was already comparing the last set of fingerprints.

And Liu Guodong rushed back from the economic investigation, and the investigation on Wang Manli also had results.
