When Qin Yong and the others went to arrest people, Lu Chuan was already asleep on the sofa in the laboratory.

stayed up all night, and Lu Chuan couldn't stand it a little.

Although it was the first time to go to the scene, the novelty overcame the boredom of the work, but then I compared the photos for a night and ran to the scene again.

When Lu Chuan woke up, he was already on the rise.

Lifting the blanket covering his body, Lu Chuan walked out of the laboratory.

In the current office, Yang Sen and Lao Bai were drinking tea and chatting.

Seeing Lu Chuan coming in, the two hurriedly got up: "Xiao Lu woke up?" ”

Yang Sen pulled out a chair and asked Lu Chuan to sit down, and Bai Wenhai took a thermos box on the desk: "The soy milk fritters made in the canteen in the morning are still hot, eat some." ”

Lu Chuan felt a little flattered.

In the half a month since he joined the company, this is the first time that Lu Chuan has not mopped the floor to clean up the office and has not made tea for his seniors.

"Thank you, Brother Bai," although Bai Wenhai's age is comparable to Lu Chuan's father, as long as he is not a leader in the unit, he is older than himself, all men are called brothers, and all women are called sisters: "Master went to a meeting?" ”

Yang Sen nodded: "Just left, the case was solved, and the team began to make a closing report." ”

"Broken?"

Lu Chuan raised his head suspiciously: "The murderer was 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 kid cleaned up the scene, his psychological quality is not good, and he heard that he was left in the car." ”

"Haha!" Yang Sen patted Lu Chuan on the shoulder: "This time, we are in the limelight, you kid must be the first to act!" ”

Lu Chuan was also very excited in his heart, after all, this was his first real case.

As for the groom's arrest at the wedding scene half a month ago, it was entirely the credit of the True Eye.

But the True Eye doesn't work in all cases, and this ability is best suited for catching wanted criminals.

When Lu Chuan is fine, he can go to sweep the streets and patrol, and maybe he will be able to solve the case and make meritorious contributions.

Yang Sen and Lao Bai looked at Lu Chuan with envy in their eyes.

When you are a police officer, who doesn't want to be rewarded for meritorious service.

But this thing is like a flower thief collecting honey, and after one time, he wants to come two more times, but his strength does not allow it.

When Yang Sen was a police officer, he saw a lot of people standing on the street, some people were fifty yuan, but some people were less than eighty.

People are beautiful and ugly, and their abilities are also high and low.

Lu Chuan is obviously handsome and powerful.

"By the way, why did Zhang Minlu kill his father, it was his own, right?"

Lu Chuan has only seen this kind of drama of father and son cannibalism in novels, and it is the first time he has experienced it in reality.

"For the money." Yang Sen lit a cigarette, blew lightly, and spit out a smoke ring, which is Lao Yang's unique skill: "Zhang Wen has an old house in Erchanggou, and he just moved last month. ”

"But Zhang Wen didn't give the money to Zhang Minlu, and gave it all to his current wife's son."

"Is that biological, too?"

Lao Bai sneered: "Biological fart, Zhang Wen's current wife's son was born to someone and her ex-husband, and it has nothing to do with Zhang Wen." ”

"Zhang Minlu's daughter has leukemia, and Zhang Wen doesn't pay a dime......"

"Grass!"

Lu Chuan spat fragrant and took the last bite of the fritters: "This old man doesn't seem to have died unjustly." ”

Bang!

While chatting, the door of the office opened, and it was the detachment leader Qin Yong.

The three of them hurriedly stood up and saluted.

"Team Qin is good!"

Qin Yong pressed down with his hands, and the smile on his face was amiable: "Everyone has worked hard, and I would like to express my condolences to the on-site survey office on behalf of the detachment." ”

Although there are few people in the current survey office, because it is a gold-swallowing beast in the detachment, a few people often see Qin Yong.

But it is not a New Year's Day condolences...... It seems like it's the first time.

"This is Xiao Lu, he is really young and promising, how is it, are you tired?"

Lu Chuan didn't expect Qin Yong to ask himself directly, and he was stunned: "It's okay, I just slept 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 body, and you can work better by taking care of your body, so that you can take a day off and adjust well." ”

Looking at Qin Yong, who was leaving with his hands behind his back, Lu Chuan was a little confused.

Didn't you make a meritorious service?

How did you get on vacation?

"Master, Team Qin...... What does that mean? ”

Liu Guodong exhaled and patted Lu Chuan on the shoulder: "Let you rest, rest, isn't it good to have a holiday?" ”

There is an unwritten rule in the criminal investigation detachment that whoever gives a holiday is a reward.

After all, the salary increase is not something one or two people say, and the commendation is not what the team says.

Verbal praise is tantamount to drawing a pie, and holidays are the most affordable reward, and everyone likes it.

In this way, when the whole detachment was still busy, Lu Chuan became the most idle person.

"Ding!"

"Advanced mission completed: The host found clues to solve the case through on-site investigation, and assisted the task force to solve the case."

"System Bonus: Beginner Footprint Analysis Skill Card."

"Does the host claim the reward?"

"Pick!"

Wow!

Streamers flickered 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 the survey, fingerprints, footprints, and DNA samples.

Because these three traces can be used as the only evidence to determine the identity of the suspect.

No one in the world has the same fingerprints, the same DNA information, and no one has the same footprint.

Everyone's footprint is unique.

In the investigation of the case, footprints are also one of the most important pieces of information extracted.

Yesterday morning, Lu Chuan lowered his head and observed the ground traces in the direction of the sun, in fact, to determine whether there were footprints.

However, in reality, the probability of using footprints to solve a crime has always been relatively low, and it is generally used as data to assist in solving crimes.

For example, Liu Guodong and others, whose footprints in their hands can only roughly judge the height and gender of their owners.

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 owner's gender.

However, in the primary footprint analysis skill card obtained by Lu Chuan, the height, weight, age and general body shape of the suspect can be determined more accurately by calculating the various proportional relationships of footprints.

One of the most complicated is the calculation of age, yes, the calculation.

There are very few traces of bare feet on the crime scene, and the vast majority of them are shoe prints.

In the footprint analysis, the age range of the owner can be determined based on the comparison of footprint data from different angles.

Highly skilled experts in footprint analysis are able to find comparison points against different footprints and derive calculated data.

The primary footprint analysis obtained by Lu Chuan was able to accurately determine the age of its owner to no more than five years old.

Lu Chuan, who had already walked out of the criminal investigation detachment, returned to the office again.

Anyway, he has nothing to do, and now that he has gained new skills, Lu Chuan plans to give it a try!
