When Qin Yong and others went to arrest the person, Lu Chuan was already lying on the sofa in the laboratory and fell asleep.
After staying up all night, Lu Chuan couldn't stand it anymore.
Although it was the first time I went to the scene, the novelty overcame the boring work, but then I compared photos all night and went to the scene again. After this lap, the iron man couldn't stand it.
It was already three o'clock in the morning when Lu Chuan woke up.
Lu Chuan opened the blanket covering his body and walked out of the laboratory.
In the current survey office, Yang Sen and Lao Bai were drinking tea and chatting.
Seeing Lu Chuan come in, the two of them quickly stood up: "Xiao Lu, are you awake?"
Yang Sen pulled out the chair and asked Lu Chuan to sit down. Bai Wenhai took a thermos box from the desk and said, "The soy milk fried dough sticks made in the cafeteria this morning are still hot. Eat some."
Lu Chuan felt quite flattered.
In half a month since joining the company, this is the first time that Lu Chuan has not mopped the floor and tidied up the office or made tea for his seniors.
"Thank you, Brother Bai." Although Bai Wenhai's age is comparable to that of Lu Chuan's father, in the unit, as long as he is not a leader, men who are older than him are always called brother and women are called sister: "Master, are you in a meeting?"
Yang Sen nodded: "I just left, the case was solved, and the team started making a closing report."
"broken?"
Lu Chuan raised his head in confusion: "Has the murderer been caught?"
"Thanks to you, the DNA information on the cigarette butt was compared and the clue was locked on Zhang Wen's son."
Bai Wenhai took over the conversation: "Although the boy cleaned up the scene, his mental quality was not good. I heard that he gave up in the car."
"Haha!" Yang Sen patted Lu Chuan on the shoulder: "We are going to be in the limelight this time, and you must be the first to do it!"
Lu Chuan was also very excited. After all, this was his first real case.
As for the arrest of the groom at the wedding half a month ago, it was entirely due to the Eye of Truth.
However, the Eye of Truth is not useful in all cases. This ability is most suitable for catching wanted criminals.
When Lu Chuan is fine, he can go sweep the streets and patrol, and maybe he can solve the case and make merit.
Yang Sen and Lao Bai looked at Lu Chuan with envy in their eyes.
As a police officer, who doesn’t want to be rewarded for meritorious service?
But this thing is like picking flowers and collecting honey. After one time, he wanted to do it twice more, but his strength didn't allow it.
When Yang Sen was a policeman, he saw a lot of people standing on the street. Some people had fifty yuan, but some had less than eighty yuan.
People are beautiful and ugly, and their abilities are also high and low.
Lu Chuan is obviously handsome and capable.
"By the way, why did Zhang Minlu kill his father? He was his biological son, right?"
Lu Chuan had only seen the drama of father and son killing each other in novels, but this was his first time experiencing it in reality.
"It's for money." Yang Sen lit a cigarette, blew gently, and blew out a smoke ring. This is Lao Yang's unique skill: "Zhang Wen has an old house in Erchanggou, and it was just moved last month."
"But Zhang Wen did not share the money with Zhang Minlu. All of it was given to his current wife's son."
"Is that also biological?"
Lao Bai then sneered: "What a piece of shit, Zhang Wen's current wife's son was born to her and her ex-husband, and has nothing to do with Zhang Wen."
"Zhang Minlu's daughter has leukemia, and Zhang Wen doesn't even have to pay a dime..."
"Grass!"
Lu Chuan spit out the fragrance and took the last bite of the fried dough stick: "It seems that this old man's death was not unjust."
boom!
While we were chatting, the office door opened and it was Qin Yong, the detachment leader.
The three people stood up quickly and saluted.
"Hello, Captain Qin!"
Qin Yong pressed his hands down with a kind smile on his face: "Thank you for your hard work. On behalf of the detachment, I would like to express my condolences to the current survey office."
Although there are few people in the current survey office, because he is the gold-swallowing beast in the detachment, Qin Yong is usually seen by a few people.
But it seems like this is the first time for me to send my condolences on a non-annual and non-holiday basis.
"This is Xiao Lu, right? He is indeed young and promising. How are you? Are you tired?"
Lu Chuan didn't expect Qin Yong to ask him directly, and was stunned: "It's not bad, I just took a nap, and I'm almost rested."
"Haha," Qin Yong stepped forward and patted Lu Chuan on the shoulder: "You still have to pay attention to your health. Only by taking good care of your body can you work better. In this way, I will give you a day off to adjust well."
Looking at Qin Yong leaving with his hands behind his back, Lu Chuan was a little confused.
Didn’t you make meritorious deeds yourself?
Why were you given a leave?
"Master, Captain Qin...what does it mean?"
Liu Guodong took a breath and patted Lu Chuan on the shoulder: "You can rest as long as you want. Isn't it better to have a holiday?"
There is an unwritten rule in the Criminal Investigation Detachment. Whoever is given a holiday will be rewarded.
After all, salary increases are not something that can be decided by just one or two people, and commendations are not decided by the team.
Verbal praise is like drawing a pie, and vacation is the most affordable reward, and everyone likes it.
In this way, while the entire detachment was still busy, Lu Chuan became the most idle person.
"Ding!"
"Advanced mission completed: The host discovered clues to solve the case through on-site investigation and assisted the task force in solving the case."
"System reward: Junior Footprint Analysis Skill Card."
"Does the host receive the reward?"
"receive!"
Wow!
Streams of light flashed in Lu Chuan's mind, and the knowledge and experience of footprint analysis were deeply rooted in Lu Chuan's mind.
Regarding footprint analysis, Lu Chuan studied at the Public Security University.
There are three most important weapons in current investigations: fingerprints, footprints and DNA testing materials.
Because these three traces can be used as the only evidence to determine the suspect's identity.
No one in the world has the same fingerprints, DNA information, or the same footprints.
Everyone's footprint is unique.
During case investigation, footprints are also one of the most important pieces of information to extract.
Yesterday morning, Lu Chuan lowered his head and observed the traces on the ground in the direction of the sun, in fact, to determine whether there were any traces of footprints.
However, in reality, the probability of using footprints to solve crimes has always been low. Generally speaking, it is used as data to assist in solving crimes.
For example, Liu Guodong and others can only roughly determine the owner's height and gender from the footprints in their hands.
The length of a normal person's footsteps is about one-seventh of their height, and the aspect ratio of the footprints can determine the gender of the owner.
However, in the elementary footprint analysis skill card obtained by Lu Chuan, he can more accurately determine the height, weight, age and approximate body shape of the suspect by calculating various proportions of the footprints.
The most complicated one is the calculation of age, yes, it is calculation.
Footprints at crime scenes rarely contain traces of bare feet; most of them are shoe prints.
In footprint analysis, the age range of the owner can be determined based on the comparison of footprint data from different angles.
Highly skilled footprint analysis experts can find comparison points for different footprints to derive calculated data.
The preliminary footprint analysis obtained by Lu Chuan was able to accurately determine the owner's age to within five years.
Lu Chuan, who had already left the criminal investigation detachment, returned to the office again.
There was nothing to do anyway. Now that he had acquired a new skill, Lu Chuan planned to give it a try!
