Chapter 11 The director's father-in-law's house was stolen
The warehouse is being inspected.
Yang Sen found a yellow cardboard box in a corner and blew away the non-existent dust 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, our investigation will be exposed!"
Seeing Yang Sen pick up the Box, Liu Guodong and Lao Bai knew what this guy was planning.
Liu Guodong nodded in agreement: "Lao Yang is right, you should read the file first."
Although Lu Chuan felt that the three of them were a little mysterious, it didn't matter to him. He had just obtained the footprint analysis skill. , Lu Chuan made great achievements in a small trial, and is now on the rise.
“Theft?”
Lu Chuan was slightly startled when he opened the file. How could there be a backlog of theft cases in the Criminal Investigation Detachment?
Theft cases are not classified into the eight categories. Generally speaking, the police station below is responsible for investigation.
There is a process for handling cases, and who will handle what type of case is determined.
It is not allowed to overstep one's level or handle cases arbitrarily.
Of course, there are some cases where the nature is not easy to determine, such as robbery and snatching.
As long as it is a robbery, no matter whether someone is injured or not, no matter how big the amount is, the minimum limit is three years. If it is a robbery on a bus, a home invasion or multiple robberies, it is more than ten years.
But for snatching, the limit is generally three years. Of course, if the amount is too large or huge, the limit can be unlimited.
There is a dividing line here. Whether there is violence or coercion during the crime, if it is, it is robbery, if not, it is another matter.
For example, if a speedster gang snatches a bag, it is possible to locate and rob it without using violence or injuring anyone.
For ordinary thefts, unless there are some cases with extremely large amounts of money and a relatively bad impact, the criminal investigation will come forward. Small cases are the matter of the police station.
As for this case, the amount involved was only more than 10,000 yuan. Oh, there was also some gold jewelry, but it didn’t seem to be related to the huge amount.
“Brother Yang, the amount of this case doesn’t seem to be very large. Why is it placed in the detachment?”
The corner of Yang Sen's mouth made an inexplicable arc: "Because the person who was stolen is special."
"Special?"
Lu Chuan opened the file and found that the person who was stolen was a man in his sixties. The old man: "Who is the leader?"
Yang Sen shook his head: "Guess again."
Where in the hell are you guessing?
Liu Guodong took out the remaining information in the box: "Don't guess, the owner is Song Jiangguo's father-in-law."
Huh?
"Who is Song Jiangguo?"
"Director..."
Lu Chuan: "..."
The case was from two years ago. Lu Chuan was reading the file and was curious: "Captain Qin... was he scolded badly?"
"No, Bureau Song is not such a stingy person."
Huh?
“It’s the car Captain Qin was riding in. It was supposed to be replaced with a new one, but it turns out it has been driving for ten years now...”
Oh.
Lu Chuan nodded, this is right.
The file is very simple. The thief who stole the crime was a habitual criminal. The scene was clean and tidy, leaving nothing behind except a series of footprints.
"We went to the scene that year. The unlocking method was very professional. He is definitely a repeat offender."
"The director's father-in-law's house was stolen. Although it didn't spread, it was considered a sensation internally. That week, the entire Haizhou City was scanned for habitual thieves, but no one was found."
"The other party was probably a mobile crime. The father-in-law of Song Bureau lived in an old community and there was no surveillance. I can only leave it like this.”
"Oh, by the way, Director Song let it slip at that time. When the case was solved, when would he change the car for Team Qin."
"Ding!"
"Advanced mission: According to The footprints of the theft were analyzed, and the physical characteristics of the suspect were analyzed, and an internal investigation was issued to assist in the arrest of the suspect. "
Still at the same desk as in the morning, Lu Chuan laid out all the photos of the footprints taken at the scene one by one, carefully. observe. "Master, didn't you ask the footprint analysis experts above to analyze the footprints?"
Liu Guodong smiled bitterly and shook his head. Because of this incident, Liu Guodong and the three of them did not raise their heads for half a year: "The father-in-law of the Haizhou City Public Security Bureau was robbed. How can we have the shame to ask others for help? The family scandal must not be made public."
< br>This is true. If we really ask for help from outsiders, Song Jiangguo can probably kill Qin Yong.
The footprints are very complete, and the suspect obviously did not pay any attention to the protective shoe prints.
Habitual thieves are like this. As long as they leave no fingerprints, no one can find them, and even if they are found, they will not admit it.
Conviction is based on footprints. Not many thieves know this.
After some observation, Lu Chuan took the millimeter ruler and started measuring the data.
Compared with the measurement of fingerprints, the error requirements for footprint measurement are not that high.
Generally speaking, the millimeter level can meet the calculation and analysis requirements.
But the measurement of fingerprints is not possible. 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 fingerprint analysts. Ordinary people... can't even use vernier calipers.
Yang Sen saw Lu Chuan starting to measure, and rubbed his hands eagerly: "Xiao Lu... haha, can we see how you operate it?"
As soon as Yang Sen spoke, Lao Bai and Liu Guodong also turned their heads. Look over.
Footprint analysis is different from fingerprint analysis. Currently, there are standard processes and mature methods for learning fingerprint analysis.
But footprint analysis is not good. What is written on paper is superficial, and the real unique skills are in the hands of a very small number of people.
For example, they know of a footprint expert from a northern province who passed it down from grandfather to son, and from son to daughter.
Therefore, if Yang Sen wanted to learn something, he needed Lu Chuan's permission.
“There’s nothing not to see here.”
Lu Chuan didn’t care, it wasn’t a secret.
It’s just that some things seem to be skill characteristics. Compared with the calculation of data, the selection of some measurement points is the 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 on-site survey photography. For other things, I relied on my seniors to teach me."
To be honest, Lu Chuan said that he has now acquired these two skills, and other skills It really doesn't work.
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.
Compared with others, Lu Chuan has no reason to be self-conscious.
When Lu Chuan said this, the atmosphere relaxed a lot, and the faces of Yang Sen and the others became less embarrassed.
However, as they watched, the three of them frowned deeply.
"Xiao Lu...why did you choose these two points for measurement?"
"Xiao Lu, is the ratio of these two data useful?"
Many things cannot be learned just by looking at them. This is just like everyone knows that Teacher Jia’s hand skills are amazing, but so many people have seen them and no one has ever heard of anyone who has learned them.
Of course, this is partly due to technical reasons, and partly due to the lack of experimental materials.
Furthermore, some naturally dry lands cannot be compared with paddy fields.
Three people asked and one answered, time passed quickly.
Five thirty-two p.m.
Looking at the manuscript paper where the calculations had been completed, Lu Chuan stretched.
"It's finally done."
On the manuscript paper, the suspect's physical characteristics have also been analyzed.
