Chapter 10 We successfully cracked a backlog of cases
Qin Yong suddenly felt that his brain was not enough.
The murder case here has not been completely closed yet. Everyone is busy fixing evidence, improving the chain of solving the case, and writing a closing report.
Considering that Lu Chuan had made great contributions in this case and discovered important clues, he was given a day off in the morning.
As a result, just a few hours later, the suspect in a backlog of robbery and wounding cases last year was arrested? !
"Bring Lu Chuan back immediately... No, arrange a car and go to the Huaguang Street Police Station!"
The murder case was not closed at that time. The murderer has already given full account, the murder weapon and the crime scene have been identified, and the rest It's all process work.
Qin Yong can have his hands free.
Three-eighteen p.m.
The interrogation room of Huaguang Street Police Station.
Huang Jianmin and another senior police officer from the police station are interrogating Zhang Yan.
Although the man was captured by Lu Chuan and Yang Lin, one of them was a field investigator and the other was a film police officer who had just been on duty for half a month. It was better not to do interrogation work.
"I...I deliberately wore a pair of shoes that my father left before his death..."
"Comrade police, I really didn't mean to hurt her. My mother is paralyzed. My daughter had to pay for school... I really had no choice that day... Wuwuwu..."
"I originally wanted to surrender...but if I went, no one would care about my child and mother... …”
When Qin Yong arrived, the interrogation was over.
Zhang Yan has already pressed his fingerprint on the interrogation record.
"Why is it a woman?"
Qin Yong came to the Huaguang Street Police Station and this was the first thing he asked.
At that time, based on the footprint analysis, it was determined that the other party was a man. But how did the suspect become a woman now?
"She wore 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: "Team Qin, what we have solved this time is a backlog of cases. We So you have to think about extra points in this year’s assessment.”
“Don’t worry, you will be indispensable.”
The handover procedures were completed quickly, and Qin Yong and his party left directly.
"Xiao Lu, you take my car, and Lao Liu, you will come too."
Qin Yong was surprised and happy when he stopped Lu Chuan, who was about to take the escort car.
Lu Chuan nodded. The detachment’s escort vehicle was a modified Iveco and was less comfortable.
Qin Yong’s car is naturally the best car in the detachment, a ten-year-old Cruiser.
Lu Chuan was sitting in the passenger seat, and Liu Guodong and Qin Yong were sitting in the back seat.
"Xiao Lu..."
Qin Yong trailed off, and Lu Chuan hurriedly turned sideways, "Captain Qin, your instructions."
"Don't be nervous, don't be nervous," Qin Yong moved his body slightly: "Today's case, well, what did you do? Find...find the murderer?"
That's what I was asking.
"You let me rest in the morning. I had nothing to do, so I went to the on-site investigation warehouse to look at the backlog of case files."
"A lot of footprints were collected at the scene of this case. I went to college. I did some research on footprint analysis when..."
Lu Chuan briefly talked about the process of analyzing the footprints to determine the suspect's characteristics, and then comparing them with the portraits extracted by nearby surveillance cameras at the 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 with shock in their eyes.
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 the premise is, experts.
What is an expert?
Liu Guodong knew that there were only two people in the province who could be called experts in footprint analysis. But this obviously does not include Lu Chuan, who has just graduated half a month ago.
There was a brief silence in the carriage.
Qin Yong didn't speak, so Lu Chuan naturally didn't say a word. Half an hour later, the car stopped at the Criminal Investigation Detachment compound.
"Xiao Lu, pay attention to rest."
Qin Yong's expression can be described as kind.
Naturally, someone from the action team took over Zhang Yan's case, and Lu Chuan could already get off work.
“Hahahaha!”
Listening to the wild laughter coming from Captain Qin’s office, the criminal police working in the detachment office whispered: “The murder case has been solved, the boss is happy, we can be normal today Are you off work?”
“Hey, as usual, it’s okay for us to take a leave or something in the next few days.”
This is also a routine. After the murder is solved, everyone can. He breathed a sigh of relief, asked for leave, came late, and left early, but turned a blind eye.
"Bureau Wang, I have good news to report to you. The robbery and wounding case last year has been solved!"
Qin Yong visited the office while asking for credit.
Lu Chuan sat on the chair, Liu Guodong, Yang Sen and Lao Bai sat opposite.
"Master, why do I feel like you are interrogating a prisoner?"
"You want to leave it alone," Qin Yong was in the car just now, and there were some things Liu Guodong couldn't say: "You Have you really done any research on footprint analysis? ”
"I can't even call it research," the system only rewards elementary footprint analysis skills, followed by intermediate and advanced levels: "I can only say that I have some experience."
Do it!
Liu Guodong and the others almost choked on Lu Chuan's words.
What does it mean to have some experience?
With just one footprint, he solved a backlog of robbery and wounding cases. This is enough 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 a male, between 1.7 and 1.8 meters tall.
But the suspect is actually a woman, 1.69 meters tall.
Liu Guodong now wants to call the "expert" in the next city and tell him what bullshit analysis you did.
It’s no wonder that Liu Guodong is successful. The investigation of all cases, even murder cases, has resource constraints.
For example, for a murder case, the criminal investigation detachment can send hundreds of people to investigate and investigate, but can it send thousands or tens of thousands of people to investigate and 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 analytical conclusion was completely different from the reality.
"Your boy has made a meritorious deed again this time. The robbery and wounding case last year was quite special, and it still attracted some attention at the time."
Speaking of this, Lu Chuan frowned and looked at Yang Sen: "Brother Yang, when we were interrogated at the Huaguang Street Police Station just now, the conditions in Zhang Yan's family seemed not to be very good. She was raising a daughter as a single parent, and her mother was paralyzed."< br>
“She robbed at that time to pay for her daughter’s tuition.”
Yang Sen was slightly stunned, obviously not aware of the situation.
"I don't know about this situation. I'm talking about the person who was robbed in particular. The victim's son has uremia, and the 800 yuan was obtained by selling her blood..."
Lu Chuan suddenly felt like his heart was blocked and he couldn't breathe.
Lao Bai shook his head and sighed: "Xiao Lu, you have just started working and have not seen 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, and anyone who steps on it must pay a price, otherwise the world will be in chaos."
"Okay, Lao Bai. , Xiao Lu is only in his early twenties, keep these big principles to yourself, let’s do something practical.”
Yang Sen interrupted Bai Wenhai and approached Lu Chuan mysteriously: “Xiao Lu, if you give me more. Just from your footprints, can you still analyze the physical characteristics of the other person? ”
"As long as the footprints are clear enough, there shouldn't be a big problem."
