Lu Chuan had been exposed to tire mark analysis when he was in school.
It’s just that the course I studied at that time was called vehicle trace analysis.
Tire tracks are part of it, and certainly the most important part.
Most crime scenes are accompanied by the presence of vehicles.
For example, in the case of corpse sinking in Xingfu Reservoir, the electric car used by the murderer to transport the corpse.
Another example is the case where Chen Yating killed Zhang Zixuan. After Chen Yating disposed of part of the body every day, she also drove away from the house where the body was hidden and returned home.
In the trunk of the car, Lu Chuan and others also detected trace amounts of blood and some small human tissues.
Compared with daggers, hammers and other weapons that can kill people, vehicles have larger targets and are harder to hide.
Therefore, in many cases, it is also a very important and common method to track down the murderer through the means of transportation he took or used.
In actual case handling, without monitoring, the analysis of tire marks is very important.
The tire tracks of vehicles are as unique as human footprints.
In judicial appraisal, it can be used as evidence for the same determination.
However, this requires a detailed identification and analysis report, not a picture, just a simple comparison.
For example, the same tire will leave different marks on different roads.
Or even under the same road conditions, different traces will be left due to differences in temperature.
The moment he received the skill card, a large amount of knowledge and experience related to tire marks filled Lu Chuan's mind.
Sitting in the car, Lu Chuan closed his eyes and rested.
Yang Sen was driving today. He wanted to experience the driving experience of the ten-year-old Cruiser.
Lu Chuan was sitting in the passenger seat, while Lao Bai and Liu Guodong were chatting in the back.
The content, of course, is also about the murder of Zhang Zixuan.
"Old Liu, by the way, the case of Big Bones last time... was also discovered by Xiao Lu and Xiao Shen, right?"
While chatting, Lao Bai suddenly remembered the cause of the case.
Liu Guodong's face was stunned, and Yang Sen, who was driving, spoke up: "Yes, yes, these two met while eating hot pot on their last date."
"This is also a date. We were supposed to go to an art exhibition to see paintings, right?"
Yang Sen's tone rose a little, and he patted Lu Chuan, who had his eyes closed to relax: "Xiao Lu, am I right?"
Lu Chuan, who had just received the system reward, opened his eyes helplessly.
"Brother Yang, we are going to have dinner, not a date."
"Okay, what's the use of you kid fooling us."
"In the past few years that Xiao Shen has been working, he has never gone out to eat alone with any of his male colleagues. You are the only one."
Lao Bai nodded in agreement: "Xiao Shen is good, do you know her father?"
Liu Guodong also nodded: "We, Xiao Lu, are not bad. This time we should at least receive a notice of praise."
Speaking of this, several people looked at Lu Chuan.
Now, this time, he showed his face again.
It seems like every time there is a case lately, the current investigation will show up.
Lu Chuan didn't care much about meritorious service or not.
Of course it would be nice to be rewarded for meritorious service. If not, he would have to ask for it or not.
What he cares about now is his and Shen Yan's reputation.
In the past two days, he had heard some bad news.
About him and Shen Yan.
It's not just tidbits.
In the criminal investigation detachment, this is not very popular.
The two of them went on dates and had meals in private, and only once or twice.
It is now popular in the team that two people found a case of human bones while eating, and a case of human skin when visiting an art exhibition.
It seems like something will happen wherever you go.
Some young detectives privately call them the Death Duo.
This means that no matter where you go, there will be murders.
"The case happened a long time ago, we just happened to run into it."
Lao Bai raised his eyebrows: "Then why can't others touch it?"
Lu Chuan: "..."
Life is like that sometimes.
We need to endure the roughness it brings to you and enjoy the pleasure it brings at the same time.
The same is true in life, just like a rich lady in a deep courtyard.
She is both afraid that you won't come, and also afraid that you will mess around.
Lu Chuan felt that he should take Shen Yan to the temple to pay homage on the weekend.
call……
He let out a long breath and hoped that nothing strange would happen in the temple.
Probably not. After all, it is a holy land of Buddhism, a place where Buddha's light shines. It should be clean. Besides, it is now a group company.
It’s November in the blink of an eye.
It has been nearly four months since Lu Chuan joined the Criminal Investigation Detachment.
Although the time was short, it should be said that the life was wonderful.
The murder case of Zhang Zixuan has also come to an end.
All evidence and materials are prepared.
Chen Yating... If nothing unexpected happens, she probably won't survive.
Having said that, it seemed that the grassroots painter got the better of him in the end.
He can still draw and still teach students.
And the age of less than fifty is when men are most attractive.
Rich, talented, and stylish.
He should have a third wife and a third child soon.
In fact, the person Chen Yating should take away the most was Liang Song, and Zhang Zixuan... died a bit unfairly.
As for the motive for the murder, it is actually very simple.
On September 21, the day Zhang Zixuan and Liang Song met in the studio, Chen Yating happened to go to deliver lotus seed porridge to Liang Song.
So I witnessed the whole process.
Chen Yating actually suspected that Liang Song had someone outside.
After all, that's how she rose to power back then.
She wanted to turn a blind eye, close one eye, and live a good life.
However, what Chen Yating did not expect was that the place where Zhang Zixuan and Liang Song rolled over was the same bed where she and Liang Song played.
Even the bed sheets were changed by Chen Yating back then.
"They shouldn't be in the studio... that's my place..."
This was Chen Yating's direct motive.
As for worshiping Buddha in the temple, Lu Chuan and Shen Yan did not go there in the end.
In order to test whether the death duo was real, the two made two appointments.
But obviously, the two dates were more successful.
Lu Chuan cleaned up the survey office early.
Now she is tending to the more delicate anthurium in front of the window.
After taking care of it for such a long time, Lu Chuan discovered that although watering and fertilizing this thing is important for daily people, it is not the most important.
The key is to stroke and play with it regularly.
In this case, the color of the anthurium will be brighter and the leaves will be moister.
Lao Bai and Yang Sen still stepped into the office.
Picking up the enamel vat in which the tea had been brewed, Lao Bai cleared his throat and sang.
The charm is very rich, and it has a style that is about to retire.
"Lao Liu went to a meeting?"
Lu Chuan nodded: "Today is the morning meeting, and it will probably last until noon."
The criminal investigation detachment has been relatively comfortable recently.
Zhang Zixuan's human skin case was over, and everyone breathed a sigh of relief.
Take a vacation when it's time to take a vacation, and have a meeting when you should have a meeting.
But such days usually don't last long.
It's not that there are any cases that have occurred, but that the original backlog of cases requires support from the criminal police brigade of various districts and counties below.
In the past two days, Xian Kan received a request for technical assistance from a high-tech zone criminal police brigade.
