Qin Yong suddenly felt that his brain was a little insufficient.

The murder case here has not been completely closed, and all the people are busy fixing the evidence, improving the chain of solving the case, and writing the closing report.

Considering that Lu Chuan made great contributions in this case and found important clues, he was given a holiday in the morning.

As a result, it has only been a few hours, and the suspect in a robbery and wounding case last year has been arrested?!

"Let Lu Chuan come back immediately...... No, arrange a car and go to the Huaguang Street police station! ”

The closure of the murder case is not at once, the murderer has all been confessed, the murder weapon and the crime scene have been identified, and the rest is the process work.

Qin Yong could spare his hands.

3:18 p.m.

The interrogation room of the Wah Kwong Street Police Station.

At the police station, Huang Jianmin and another senior police officer are interrogating Zhang Yan.

Although the people were arrested by Lu Chuan and Yang Lin, one of them is on the spot, and the other is a film police officer who has just been on duty for half a month, so it is better not to contact this kind of work for interrogation.

"I ...... I deliberately wore a pair of shoes that my father left over from before he died......"

"Comrade policeman, I really didn't mean to hurt her, my mother is paralyzed, and my daughter has to pay for school...... I really couldn't help it that day...... Woowoo woo ......"

"I wanted to turn myself in...... But if I go, my children and my mother will be left alone......"

When Qin Yong arrived, the interrogation was already over.

Zhang Yan had already pressed her handprint on the interrogation record.

"How is it a woman?"

Qin Yong came to the Huaguang Street Police Station and the first thing he said was this.

At that time, according to the footprint analysis, it was determined that the other party was a man, but now how did the suspect become a woman?

"She was wearing her father's shoes and several pairs of socks when she committed the crime."

Without Lu Chuan speaking, Director Huang Jianmin told the truth: "Team Qin, what has been cracked this time is a backlog of cases, and we have added points to this year's assessment, you have to think about it." ”

"Don't worry, you're indispensable."

The handover procedures were completed quickly, and Qin Yong and his party left directly.

"Xiao Lu, you take my car, Lao Liu, you also come."

Stopping Lu Chuan, who was about to take the escort car, Qin Yong was surprised and happy in his heart.

Lu Chuan nodded, the detachment's escort car was transformed from an Iveco, and the comfort was worse.

Qin Yong's car is naturally the best car in the detachment, the ten-year-old Cruiser.

Lu Chuan sat in the co-pilot, and Liu Guodong and Qin Yong sat in the back seat.

"Xiao Lu, ......"

Qin Yong made a drag, and Lu Chuan hurriedly turned sideways slightly, "Team Qin, you instruct." ”

"Don't be nervous, don't be nervous," Qin Yong moved his body slightly: "Today's case, well, how did you find it...... Found the murderer? ”

It turned out to be asking this.

"You let me rest in the morning, and I will go to the current investigation warehouse to see the backlog of case files if I have nothing to do."

"At the scene of this case, a lot of footprints were collected at that time, and I had some research on footprint analysis when I was in college......"

Lu Chuan briefly described the process of analyzing the footprints to get the characteristics of the suspect, and then comparing them with the portraits extracted from the nearby surveillance at that time.

"You mean...... Through the analysis of footprints, you can determine the gender, height, age, and ...... of the suspect X-shaped legs? ”

Lu Chuan nodded: "Well, the calculation is a bit cumbersome, but it's actually not too difficult." ”

Not too difficult?

Qin Yong and Liu Guoliang glanced at each other, and both of them were shocked in their eyes.

Of course the two of them know about footprint analysis.

It is also known that some experts can accurately analyze the physical characteristics of the owner through the footprints.

But only if the premise, experts.

What is an expert?

Liu Guodong knows that there are only two people in the province who can be called experts in footprint analysis.

But this obviously does not include Lu Chuan, who has just graduated for half a month.

There was a brief silence in the carriage.

Qin Yong didn't speak, Lu Chuan naturally didn't squeak, and half an hour later, the car stopped in the compound of the criminal investigation detachment.

"Xiao Lu, pay attention to rest."

Qin Yong's expression can be described as kindness.

Zhang Yan's case was naturally taken over by someone from the action team, and Lu Chuan was already able to get off work.

"Hahahaha!"

Listening to the wild laughter in Captain Qin's office, the criminal police working in the detachment organ whispered: "The murder case has been solved, the boss is happy, can we get off work normally today?" ”

"Hehe, according to the usual practice, let's take a leave of absence in the next few days."

This is also a common practice, after the murder is solved, all personnel can breathe a sigh of relief, ask for leave, be late, and leave early with one eye and one eye.

"Wang Bureau, I have good news for you, the case of robbery and injury last year has been handled!"

While asking for credit, Qin Yong visited the office.

Lu Chuan sat on the chair, Liu Guodong, Yang Sen and Lao Bai sat opposite.

"Master, how do I feel like a prisoner?"

"You don't want to care," just now in the car, there was Qin Yong, and there were some things that Liu Guodong couldn't say: "You really have research on footprint analysis?" ”

"I can't talk about research," the system rewards only the basic footprint analysis skills, and there are two levels of intermediate and advanced in the back: "It can only be said that it is a little experience." ”

Dry!

Liu Guodong and the three of them were almost choked by Lu Chuan's words.

What do you mean by a little experience?

With a footprint, a backlog of robbery and wounding cases was solved, which is already able to make a TV series.

The point is that at that time, the Haizhou City Criminal Investigation Detachment invited "experts" from the next city to analyze the footprints.

At that time, it was concluded that the suspect was male, between 1.7 and 1.8 meters tall.

But in fact, the suspect is a woman, 1.69 meters tall.

Liu Guodong can't wait to call the "expert" in the city next door now and tell the other party what bullshit analysis you have done.

It's no wonder that Liu Guodong is a villain, and the investigation and handling of all cases, even if they are murders, are limited by resources.

For example, in a homicide case, the criminal investigation detachment can send hundreds of people to find out the platoon, but can it send thousands or tens of thousands of people to find out the platoon?

The same is true for trace identification, if you can't do it yourself, you can only ask others, but others also have their own cases to solve.

At this time, you can only say good things and owe favors.

As a result, the favor was owed, but the analysis conclusion was far from the reality.

"Your kid has made meritorious service again this time, the robbery and wounding case last year was quite special, and it still attracted a certain amount of attention at that time."

Speaking of this, Lu Chuan frowned and looked at Yang Sen: "Brother Yang, when I was interrogated at the Huaguang Street Police Station just now, the conditions in Zhang Yan's family didn't seem to be very good, she raised a daughter alone, and her mother was still paralyzed. ”

"She robbed at that time to pay for her daughter's tuition."

Yang Sen was slightly stunned, obviously not knowing this situation.

"I don't know about this situation, I'm talking about the person who was robbed, the victim's son has uremia, and the 800 yuan was exchanged for her blood ......"

Lu Chuan suddenly felt his heart blocked, and he couldn't breathe.

Lao Bai shook his head and sighed: "Xiao Lu, you just went to work, you still don't know much, most people commit crimes for a reason, such as Zhang Minlu killing his father." ”

"But, no matter what, hardship is never an excuse for sin."

"The law is the bottom line, and anyone who steps on it must pay the price, otherwise the world will be chaotic."

"Okay, Lao Bai, Xiao Lu is only in his early twenties, you can keep these big truths for yourself, let's have something practical."

Yang Sen interrupted Bai Wenhai and approached Lu Chuan mysteriously: "Xiao Lu, if I give you another footprint, can you still analyze the physical characteristics of the other party?" ”

"As long as the footprints are clear enough, there shouldn't be much of a problem."
