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

Chapter 11
Currently surveying the warehouse.

Yang Sen found a yellow cardboard box in a corner, and blew away the dust that didn't exist on it. The warehouse with constant temperature and humidity was very clean.

"Xiao Lu, this case has some background. If you can find the suspect in this case, we will show our face in the present investigation!"

Seeing the box Yang Sen picked up, Liu Guodong and Lao Bai knew what this guy was up to.

Liu Guodong nodded in agreement: "Old Yang is right, you should read the file first."

Although Lu Chuan felt that the three of them were a bit mysterious, it didn't matter to him. He just got the footprint analysis skills, and Lu Chuan made a great contribution in a small test, and now he is on the rise.

"Theft?"

Lu Chuan, who opened the file, was slightly taken aback. How could there be a backlog of theft cases in the Criminal Investigation Detachment?

Theft cases are not one of the eight major categories of cases. Generally speaking, the police station below is responsible for the investigation.

There is a process for handling cases, and it is stipulated who will handle what type of case.

Handling cases by leapfrogging or arrogating to others is not allowed.

Of course, the nature of some cases is not easy to determine, such as robbery and robbery.

As long as it is a robbery, no matter whether it hurts people or not, no matter how much the amount is, the lower limit is three years. If it is a bus, burglary or multiple robberies, it is more than ten years.

However, in terms of snatching, generally speaking, there is a three-year cap. Of course, if the amount is too large or huge, it can be indefinite.

There is a boundary here, whether there is violence or coercion in the crime process, if there is, then it is robbery, if not, then it is another matter.

For example, if the speeding party snatches a bag, if it does not use violence and does not hurt anyone, then it is possible to locate and snatch it.

In the case of ordinary theft, unless there are some particularly huge cases with relatively bad impact, criminal investigation will come forward, and small cases are the affairs of the police station.

And in this case, the amount involved was only more than 1 yuan. Oh, and there are some gold jewelry, but it seems that the huge amount can't be linked.

"Brother Yang, the amount of money in this case doesn't seem too big, why is it placed in the detachment?"

An inexplicable arc was drawn at the corner of Yang Sen's mouth: "Because this person who was stolen is quite special."

"special?"

Lu Chuan opened the file and found that the stolen person was an old man in his 60s: "What leader?"

Yang Sen shook his head: "You guess again."

Where can I guess.

Liu Guodong took out the remaining information in the box: "Don't guess, the owner is Song Jiangguo's father-in-law."

Ok?
"Who is Song Jiangguo?"

"Director..."

Lu Chuan: "..."

The case was two years ago. Lu Chuan was curious while reading the file: "Captain Qin... was scolded badly?"

"No, Bureau Song is not such a stingy person."

Ok?
"It's the car Team Qin was riding in. It was supposed to be replaced with a new one, but it's been running for ten years now..."

Oh.

Lu Chuan nodded, that's right.

The dossier is very simple. The thief who stole is a habitual offender. The scene is clean and neat, leaving nothing but a series of footprints.

"We went to the scene back then. The method of unlocking the lock was very professional, and it was definitely a repeat offender."

"The bureau chief's father-in-law's house was stolen. Although it didn't spread, it was considered a sensation internally. That week, all the habitual thieves in Haizhou City were scanned, but they were not found."

"The other party is likely to commit a mobile crime. Mr. Song's family lives in an old community, and there is no surveillance. In the end, we can only leave it like this."

"Oh, by the way, Director Song let the word go. When the case is solved, when will Team Qin change the car."

"Ding!"

"Advanced task: According to the footprints of the theft case, analyze the physical characteristics of the suspect, release the wanted internal assistance investigation, and assist in the arrest of the suspect."

Still at the desk in the morning, Lu Chuan arranged all the photos of footprints taken on the spot one by one, and observed them carefully.

"Master, didn't you find the footprint analysis experts above to analyze the footprints?"

Liu Guodong smiled wryly and shook his head. Because of this incident, Liu Guodong and the others didn't raise their heads for half a year: "The Haizhou Public Security Bureau chief's father-in-law's house was stolen. We don't have the face to ask others for help. We can't show our ugliness."

What he said was true, if he really needed help from an outsider, Song Jiangguo would probably be able to kill Qin Yong.

The footprints are very complete, and the suspect obviously didn't work hard on the protective shoe prints.

Habitual thieves are like this, as long as they don't leave fingerprints, no one can find them, and if they find them, they won't admit it.

Convicted by footprints, few thieves know this.

After observing, Lu Chuan took the millimeter ruler and began to measure the data.

The measurement of footprints is less demanding than the measurement of fingerprints.

Generally speaking, the millimeter level can meet the calculation and analysis requirements.

But the measurement of fingerprints is not enough. Compared with footprints, fingerprints are smaller. When measuring, vernier calipers are mostly used, and sometimes laser measurement is even required.

Of course, the latter is only used by expert-level fingerprint analysts, and ordinary people... can't even use vernier calipers.

Yang Sen watched Lu Chuan start measuring, and rubbed his hands eagerly: "Xiao Lu...haha, can we see how you operate?"

As soon as Yang Sen spoke, Lao Bai and Liu Guodong also turned their heads to look over.

Footprint analysis is different from fingerprint analysis. At present, there are standard procedures and mature methods for learning fingerprint analysis.

But the footprint analysis is not good, the things written on the paper are superficial, and the real unique skills are in the hands of very few people.

For example, they know of a footprint expert in a northern province who passed it down from grandfather to son, son to daughter, and so on.

Therefore, Yang Sen wanted to learn and asked for Lu Chuan's permission.

"There's nothing you can't see here."

Lu Chuan doesn't care, it's no secret.

It’s just that some things seem to be technical characteristics. Compared with the calculation of data, the selection of some measurement points is that intuition or experience.

As soon as Lu Chuan got started, he knew which point to choose.

"When I was in college, I had some experience in footprint analysis and site survey photography. I can rely on my seniors to teach me other things."

Lu Chuan is telling the truth, he has acquired these two skills now, and the others are really not good.

And both Liu Guodong and Yang Sen Laobai took good care of Lu Chuan.

When I was surveying yesterday, I did not hesitate to teach some tips.

Comparing his heart to his heart, Lu Chuan has no reason to cherish himself.

When Lu Chuan said this, the atmosphere eased a lot, and the faces of Yang Sen and the other three became less embarrassed.

However, looking at it, the three of them frowned deeply.

"Little Lu...why did you choose these two points for measurement?"

"Xiao Lu, what is the use of the ratio of these two data?"

Many things can't be learned just by looking at them. It's like everyone knows that Teacher Jia's hand skills are unique, but so many people have seen it, and no one has heard of it.

Of course, on the one hand, there are technical reasons, and on the other hand, there is a lack of experimental materials.

Furthermore, some naturally dry lands cannot be compared with paddy fields.

Three people asked and one person answered, time passed quickly.

32:[-] p.m.

Looking at the manuscript paper that has been calculated, Lu Chuan stretched.

"It's finally done."

On the manuscript paper, the physical characteristics of the suspect have also been analyzed.
