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

Chapter 7
When Qin Yong and others went to arrest him, Lu Chuan had already fallen asleep on the sofa in the laboratory.

After staying up all night, Lu Chuan couldn't stand it anymore.

Although it was the first time he appeared on the scene, the novelty overcame the boring work, but then he compared the photos all night, and went to the scene again. After this round of tossing, Iron Man couldn't stand it.

When Lu Chuan woke up, the sun was already high.

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

Currently surveying the office, Yang Sen and Lao Bai are drinking tea and chatting.

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

Yang Sen pulled out the chair and asked Lu Chuan to sit down. Bai Wenhai took an insulated box from the desk: "The soy milk fritters made in the cafeteria in the morning are still warm, eat some."

Lu Chuan felt rather flattered.

Since joining the company for half a month, this is the first time that Lu Chuan has not mopped the floor to clean up the office, nor has he made tea for his seniors.

"Thank you, Brother Bai." Although Bai Wenhai's age is comparable to that of Lu Chuan's father, as long as he is not a leader and older than himself in the unit, all men are called Brother and women are all called Sister: "Master has a meeting?"

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

"broken?"

Lu Chuan raised his head in doubt: "Caught the murderer?"

"It's not 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 mental quality is not good. I heard that he was left in the car."

"Haha!" Yang Sen patted Lu Chuan on the shoulder: "This time we found out that we are in the limelight, and you must be the first!"

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

As for the arrest of the bridegroom officer at the wedding half a month ago, it was entirely due to the Eye of Truth.

But the Eye of Truth is not useful in all cases, this ability is most suitable for catching wanted criminals.

When Lu Chuan is free, he can go to sweep the streets and patrol the streets, maybe he can solve the case and make meritorious service.

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

As a policeman, who doesn't want to be rewarded for meritorious service.

But this thing is like a flower picker picking honey. After one time, he also wants to come twice more, but his strength does not allow it.

When Yang Sen was a policeman, he saw a lot of people standing on the street. Some people paid 50 yuan, while others couldn't afford [-] yuan less.

People have beauty and ugliness, as well as abilities.

Lu Chuan is obviously tall, handsome and capable.

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

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

"It's for the money." Yang Sen lit a cigarette, blew lightly, and exhaled a smoke ring. This is Lao Yang's unique skill: "Zhang Wen has an old house in Erchanggou, which was 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 also your own?"

Lao Bai continued to sneer: "Birth fart, Zhang Wen's current wife's son was born to his ex-husband, and has nothing to do with Zhang Wen."

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

"Grass!"

Lu Chuan breathed out the fragrance, and bit the last bite of fried dough sticks: "It seems that the old man died for no reason."

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

The three hurriedly stood up and saluted.

"Hello Team Qin!"

Qin Yong pressed his hands down, with a friendly smile on his face: "Everyone has worked hard. 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 they are the gold-swallowing beasts in the detachment, they often see Qin Yong.

But the sympathy for non-year-old festivals... seems to be the first time.

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

Lu Chuan didn't expect Qin Yong to ask himself directly, and he froze his head: "It's okay, 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 body, and you can work better with a healthy body. In this way, let you take a day off and make adjustments."

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

Didn't you make meritorious service?

How did you get a holiday?

"Master, Captain Qin...what do you mean?"

Liu Guodong let out a sigh of relief, and patted Lu Chuan on the shoulder: "If you are told to rest, rest, isn't it good to have a holiday?"

There is an unwritten rule in the criminal investigation detachment, whoever is given a holiday is rewarded.

After all, the matter of salary increase is not decided by one or two people, and the commendation is not decided by the team.

Verbal praise is tantamount to painting a big cake, and vacation is 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 task completed: The host found clues to solve the case through on-site investigation, and assisted the task force to solve the case."

"System Reward: Elementary Footprint Analysis Skill Card."

"Does the host receive the reward?"

"receive!"

Whoa!
Streams of light flickered in Lu Chuan's mind, and the knowledge and experience of footprint analysis were deeply rooted in Lu Chuan's mind.

Lu Chuan had studied footprint analysis at the Public Security University.

There are three most important weapons for current surveys, 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, DNA information, or the same footprints.

Everyone's footprint is unique.

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

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

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

For example, Liu Guodong and others, the footprints in their hands can only roughly determine the owner's height and gender.

A normal person's footsteps are about one-seventh the length of their height, and the aspect ratio of a footprint can determine the sex of the owner.

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

The most complicated one is the calculation of age, yes, it is calculation.

Footprints at crime scenes rarely show barefoot marks, and the vast majority 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.

A highly skilled footprint analysis expert can find comparison points for different footprints, so as to obtain calculation data.

The rudimentary footprint analysis obtained by Lu Chuan was able to pinpoint the age of its owner to within five years of age.

Lu Chuan, who had already left the Criminal Investigation Detachment, returned to the office again.

Anyway, I have nothing to do, now that I have acquired a new skill, Lu Chuan plans to give it a try!
