Qin Yong suddenly felt that his brain was a bit overwheld.
The murder case here had not been completely closed yet, and everyone was busy securing evidence, perfecting the case-solving chain, and writing the case closing report.
Considering that Lu Chuan made a great contribution to this case by discovering important clues, he was given ti off in the morning.
But in just a few hours, they captured a suspect from an unresolved robbery and injury case from last year?!
"Get Lu Chuan back imdiately... no, arrange a car to go to the Huaguang Street police station!"
The closing of the murder case wasn’t urgent; the perpetrators had confessed, and the weapon and cri scene were identified. What was left was just procedural work.
Qin Yong could free up his hands.
3:18 PM.
Interrogation room at Huaguang Street police station.
At the station, Huang Jianmin and another veteran officer were interrogating Zhang Yan.
Although Lu Chuan and Yang Lin were the ones who caught her, one was a cri scene investigator, and the other had only been on the job for half a month as a beat cop, so it was best for them not to engage in interrogation work.
"I... I deliberately wore a pair of shoes left by my father before he passed away..."
"Officer, I really didn’t an to hurt her, my mother is paralyzed, and my daughter needs money for school... I was really desperate that day... sob sob sob..."
"I originally wanted to turn myself in... but if I did, no one would take care of my child and mother..."
When Qin Yong arrived, the interrogation had already concluded.
Zhang Yan had already placed her handprint on the interrogation record.
"How is it a woman?"
The first question Qin Yong asked upon arriving at the Huaguang Street police station was this.
Based on footprint analysis, it was determined that the suspect was male. So how did the suspect turn out to be female?
"She wore her father’s shoes during the cri and put on several pairs of socks."
Without Lu Chuan speaking, Director Huang Jianmin revealed the truth: "Captain Qin, this is an unresolved case we cracked, you should rember this for our annual evaluation."
"Don’t worry, you won’t be forgotten."
The handover procedures were completed quickly, and Qin Yong and his team left directly.
"Lu, you co with , Old Liu, you too."
Stopping Lu Chuan, who was about to take the escort vehicle, Qin Yong felt both surprised and delighted.
Lu Chuan nodded; the team’s escort car was a modified Iveco, less comfortable.
Qin Yong’s car was naturally the best in the team, a ten-year-old Land Cruiser.
Lu Chuan sat in the passenger seat, with Liu Guodong and Qin Yong in the back.
"Lu..."
Qin Yong dragged out his words, and Lu Chuan quickly turned slightly, "Captain Qin, your instructions."
"Don’t be nervous, don’t be nervous," Qin Yong shifted slightly: "This case today, um, how did you find... discover the suspect?"
Turned out he was asking about this.
"You let rest in the morning, with nothing to do, I went to the evidence storage to check case files."
"At the scene of this case, many footprints were collected. Back in university, I did so research on footprint analysis..."
Lu Chuan briefly narrated the process of analyzing the footprints, determining the suspect’s characteristics, and then comparing them with images extracted from nearby surveillance at that ti.
"Are you saying... you determined the suspect’s gender, height, age, and... knock-kneed condition through footprint analysis?"
Lu Chuan nodded: "Yes, it was a bit tedious to calculate, but actually, it wasn’t too difficult."
Not too difficult?
Qin Yong and Liu Guoliang exchanged glances, both eyes filled with shock.
They knew about footprint analysis.
And knew that so experts could accurately analyze the owner’s physical characteristics through footprints.
But the premise was, expert.
What qualifies as an expert?
Liu Guodong knew that in the whole province, there were only two who could be called experts in footprint analysis.
But it clearly did not include Lu Chuan, who had just graduated for half a month.
The car interior fell into a brief silence.
Qin Yong remained silent, so naturally, Lu Chuan wouldn’t speak either. Half an hour later, the car stopped at the Criminal Investigation Team’s courtyard.
"Lu, make sure to rest well."
Qin Yong’s expression could be described as kind.
Zhang Yan’s case was naturally handed over to the action team, allowing Lu Chuan to clock out.
"Hahahaha!"
Listening to the hearty laughter coming from Captain Qin’s office, the criminal police working in the team’s office whispered: "The murder case is solved, the boss is happy, can we leave work on ti today?"
"Hehe, as per usual, we can take a leave or sothing for the coming days without any problem."
This was customary; after a murder case was solved, everyone could relax, taking leave, being late, and leaving early were all overlooked.
"Director Wang, reporting good news, last year’s robbery and injury case is solved!"
While Qin Yong was taking credit, at the cri scene investigation office.
Lu Chuan sat in a chair, facing Liu Guodong, Yang Sen, and Old Bai.
"Master, why do I feel like you’re interrogating a suspect?"
"Don’t bother with that," having just been in the car with Qin Yong where he couldn’t speak freely, Liu Guodong said: "You really have researched footprint analysis?"
"Not exactly researched," the system only awarded him basic footprint analysis skills, with interdiate and advanced levels above that: "I can only say I have so insights."
Damn!
The three of them were almost choked by Lu Chuan’s words.
What does having so insights an?
Solving a robbery and injury cold case with a single footprint, this could freaking be a TV series.
The point was, at that ti, Haizhou City’s Criminal Investigation Team even invited an "expert" from the neighboring city to analyze the footprint.
The conclusion then was that the suspect was male, between 170-180 cm in height.
But in fact, the suspect was female, with a height of 169 cm.
Liu Guodong was eager to call the neighboring city’s "expert" and tell him what lousy analysis he had done.
But you couldn’t bla Liu Guodong for being smug; handling cases, even major ones, had resource limits.
For instance, for a major case, the Criminal Investigation Team could deploy hundreds to search, but could they send thousands, even tens of thousands?
The sa went for trace identification; if you can’t do it yourself, you have to ask others, but others have their own cases to solve.
And so, you could only speak nicely and owe favors.
In the end, the favor was owed, but the analysis conclusion diverged drastically from reality.
"You’ve made another contribution this ti; last year’s robbery case was quite special, garnering so attention back then."
At this, Lu Chuan frowned, looking at Yang Sen: "Brother Yang, during the interrogation at Huaguang Street police station just now, it seed Zhang Yan’s family wasn’t doing well; she was a single parent supporting a daughter, and her mother was paralyzed."
"She robbed to pay for her daughter’s tuition."
Yang Sen was slightly stunned, clearly unaware of this situation.
"I didn’t know about this, but the special aspect I was referring to was the victim of the robbery; her son has uremia, and that 800 yuan was money she got from selling blood..."
Lu Chuan suddenly felt a heavy block in his chest, unable to catch a breath.
Old Bai shook his head and sighed: "Lu, you’re new, so you haven’t seen much. Most people have reasons for committing cris, like Zhang Minlu killing his father."
"But no matter what, hardship is never an excuse for cri."
"The law is the bottom line, and anyone who crosses it must pay the price, or the world would be in chaos."
"Alright, Old Bai, Lu is just in his early twenties, keep your big truths to yourself; let’s get to sothing practical."
Yang Sen interrupted Bai Wenhai, leaning in mysteriously to Lu Chuan: "Lu, if I give you another footprint, could you analyze the physical characteristics again?"
"As long as the footprint is clear enough, there shouldn’t be a problem."
