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

Chapter 10 We have successfully cracked a backlog

Qin Yong suddenly felt that his brain was not enough.

The murder case here has not been completely closed, and everyone is busy fixing the evidence, perfecting the chain of solving the case, and writing the closing report.

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

As a result, only a few hours later, the suspect in the backlog of robbery and wounding cases last year was arrested? !
"Let Lu Chuan come back immediately... No, arrange a car and go to the Huaguang Street Police Station!"

The murder case is not closed in a short while, the murderer has already fully confessed, the murder weapon and the crime scene have been identified, and the rest is procedural work.

Qin Yong could free up his hands.

Three eighteen in the afternoon.

The interrogation room of the Huaguang Street Police Station.

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

Although Lu Chuan and Yang Lin were the ones who brought him back, one of them is a surveyor, and the other is a police officer who has just been on duty for half a month. It is better not to have any contact with interrogation.

"I... I deliberately wore a pair of shoes that my father left 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 do anything that day... woo woo woo..."

"I originally wanted to surrender...but if I go, my children and mother will be left alone..."

When Qin Yong arrived, the interrogation had already ended.

Zhang Yan has already pressed her fingerprint on the interrogation record.

"Why is it a woman?"

When Qin Yong came to the Huaguang Street Police Station, this was the first sentence he asked.

At that time, according to the footprint analysis, it was determined that the other party was a man, but how did the suspect become a woman now?
"She was wearing her father's shoes and several pairs of socks when she committed the crime."

Without Lu Chuan's words, director Huang Jianmin told the truth: "Captain Qin, this time we have uncovered a long-standing case. Our office will get extra points in this year's assessment. You have to think about it."

"Don't worry, you are indispensable."

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

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

Calling to stop Lu Chuan who was going to take the escort car, Qin Yong was both surprised and happy.

Lu Chuan nodded. The escort vehicle of the detachment was remodeled by Iveco, which was less comfortable.

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

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

"Little Lu..."

Qin Yong dragged his voice, and Lu Chuan hurriedly turned his body slightly, "Captain Qin, please give instructions."

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

Originally asked this.

"You let me rest in the morning. I have nothing to do, so I went to the current survey warehouse to look at the files."

"A lot of footprints were collected at the scene of this case. I did some research on footprint analysis when I was in college..."

Lu Chuan briefly explained how he obtained the characteristics of the suspect by analyzing the footprints, and then compared it with the portraits extracted from nearby surveillance at that time.

"You mean...you determined the suspect's gender, height, age, and... X-shaped legs through footprint analysis?"

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 looked at each other, both of them were shocked.

Of course the two of them knew about footprint analysis.

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

But only if, experts.

What is an expert?

As far as Liu Guodong knew, there were only two experts in the province who could 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, so Lu Chuan naturally didn't say anything. Half an hour later, the car stopped at the compound of the Criminal Investigation Detachment.

"Xiao Lu, pay attention to rest."

Qin Yong's expression can be described as kind.

Zhang Yan's case will naturally be taken over by the action team, and Lu Chuan can already get off work.

"Hahahaha!"

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

"Hey, according to the usual practice, it's okay for us to ask for a vacation or something in the next few days."

This is also a common practice. After the murder case is solved, all the staff can breathe a sigh of relief, ask for leave, be late, and leave early all turn a blind eye.

"Director Wang, I have some good news for you. Last year's case of robbery and wounding was settled!"

While asking for credit, Qin Yong is currently surveying the office.

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

"Master, why do I feel like you are interrogating a prisoner?"

"You don't want to worry about it," just now in the car, with Qin Yong present, there are some things Liu Guodong can't say: "Do you really have research on footprint analysis?"

"It's not really research." The system only rewards elementary footprint analysis skills, and there are two levels of intermediate and advanced levels behind: "It can only be said to be a bit of experience."

Dry!
The three of Liu Guodong almost choked on Lu Chuan's words.

What is a little experience?

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

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

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

But in fact the suspect is a woman with a height of 1.6 meters nine.

Liu Guodong can't wait to call the "expert" in the next city right now and tell him what bullshit analysis you did.

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

For example, in a murder case, the Criminal Investigation Detachment can send hundreds of people to investigate, but can it send thousands or tens of thousands of people to investigate?
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, I can only say good things and owe favors.

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

"Your kid has made meritorious service again this time. Last year's robbery and wounding case 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 he was interrogated at the Huaguang Street Police Station just now, the conditions in Zhang Yan's family seemed to be not very good. She raised a daughter by a single parent, and her mother was still paralyzed."

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

Yang Sen was taken aback for a moment, obviously not aware of the situation.

"I don't know about this situation. I'm talking about the person who was robbed. The victim's son has uremia. The 800 yuan was bought by her selling blood..."

Lu Chuan suddenly felt his heart blocked and he couldn't catch his breath.

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

"But, in any case, hardship is never an excuse for crime."

"The law is the bottom line. Anyone who tramples on it will have to pay the price, otherwise the world will be in chaos."

"Okay, Lao Bai, Xiao Lu is only in his early twenties, you can keep these big principles to yourself, let's get some practical things."

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

"As long as the footprints are clear enough, it shouldn't be a big problem."
