Thirteen murder cases left unresolved, and seven were solved within four days.
In any fingerprint battle, this is an extraordinary achievent.
And Lu Chuan's task in this fingerprint battle is essentially completed.
Among the remaining six cases, it can be confird that the sa person is the murderer in two of them.
These are the murder of Detective Zheng Bin and the case of the female corpse falling from a building in Qingjian District.
These two cases can be combined for investigation.
Moreover, the murders were nine years ago and five years ago, respectively.
Who can guarantee that the murderer didn't kill again during this period?
No one can be sure how many lives were taken.
The case has been smoothly handed over to the Criminal Investigation Team.
Ren Qiang now has a massive headache.
Too much ti has passed, and there are very few clues discovered.
Hard to manage...
Of course it's not easy, otherwise, it wouldn't have beco a cold case.
In fact, in recent years, as soon as a murder case occurs, the murder investigation chanism is activated imdiately.
Without delving into the process, the short description is to spare no effort and ignore resources to solve the case.
Tianzhou City once collected fingerprints from the people of an entire county for a murder case.
Furthermore, Lu Chuan heard that for a series of Qiang Jian murder cases, the murderer's DNA information was collected, and the DNA of tens of thousands was also collected.
And then comparisons were made.
This is the essence of the murder chanism, at any cost.
For the other four cases, Lu Chuan tried various thods to pre-process the fingerprints.
But analysis success remained elusive.
It can be inferred that the murderer's fingerprint information is no longer in the database.
In such a situation, it is up to fate.
Maybe soday the murderer's fingerprints will be collected.
Lu Chuan has completed the pre-processing of the involved fingerprints, waiting for the system comparison.
Most of the ti, as long as the fingerprints are collected, the culprit can't escape.
Of course, if one has the resolve to destroy their own fingerprints with sothing like acid, perhaps they could indeed evade the law.
Lu Chuan had seen a similar case in college.
Because the murderer's fingerprints were accidentally destroyed, they killed without any attempts to conceal it.
But the police were unable to find the suspect based on fingerprints.
On the fifth day of the battle, most people were in a state of lying flat.
After four days of effort, the simple cases provided by the municipal bureau this year were all sorted out.
So relatively simple cold cases had been pondered over adequately by everyone.
To make further progress...
Difficult.
The municipal bureau leaders, especially Wang Kai, knew when to stop.
In this situation, it was decided to end the fingerprint battle early and hold a grand comndation for the achievents.
At the eting, Lu Chuan and Sun Hao wore large red flowers, each receiving certificates from the leaders.
Sun Hao, a personal third-class rit.
Lu Chuan, a personal first-class rit!
This was sothing that Lu Chuan did not anticipate.
He just sat in front of the computer for a few days and received a first-class rit!
A cash reward of 20,000 yuan, and a promotion in police rank can be granted one to two years ahead of ti!
Was this already achieved?
Lu Chuan felt a sense of unreality.
Having been in the police force for over half a year, he had been involved in more than a dozen cases.
He had even risked his life more than once.
But the most he had ever earned was a second-class rit.
This ti, sitting in front of a computer for a few days, he actually got a first-class rit?
Lu Chuan saluted on stage, the dal on his chest personally pinned by Song Jiangguo.
With a large red flower, holding the certificate in hand.
Below the stage were all the heads of district and county sub-bureaus and the Criminal Investigation Team, except those on duty at the scene, including Qin Yong.
The ceremony was short, but Song Jiangguo's speech was long.
Lu Chuan didn't find it verbose, after all, anyone with a freshly pinned first-class rit dal wouldn't think a leader's speech was verbose.
"Congratulations!"
The comndation ceremony ended, and Qin Yong patted Lu Chuan's shoulder hard, making a resounding noise.
Alive and receiving a first-class rit as a detective, in the entire Haizhou City Public Security Bureau, you could count them on one hand.
"Captain Qin... I just feel it's not very real..."
Lu Chuan touched the dal on his chest, still feeling like he was dreaming.
Qin Yong shook his head with a bitter smile.
Not very real...
He also felt it wasn't very real.
After all, fingerprint battles like this are held every year and are always the sa.
Before Lu Chuan ca, Liu Guodong always took the lead, solving two or three cases within seven days, securing the first place.
He could represent the Haizhou City Public Security Bureau to participate in the fingerprint battle organized by the provincial departnt.
But this ti, not to ntion others, just Lu Chuan alone solved seven cases.
In past years, this might have been everyone's total achievent.
And the seven cases Lu Chuan successfully analyzed were all unsolved murder cases!
What kind of cases can beco cold cases, are those that a whole Criminal Investigation Team can't solve.
This first-class rit of Lu Chuan essentially equaled the work of six Criminal Investigation Teams.
It can be said Lu Chuan, with just his personal efforts, solved seven murder cases.
Seven murder cases!
In these peaceful tis, this is already an outstanding number of cases.
Lu Chuan's personal first-class rit dal was awarded after the municipal bureau consulted with the provincial departnt and received approval.
"Captain Qin, do you think... we should talk to Teacher Lu first?"
The Publicity Departnt of the municipal bureau interrupted Lu Chuan's thoughts.
At that mont, they were ready to descend on Lu Chuan with caras and recorders.
If Lu Chuan's success in solving seven cold murder cases through fingerprint analysis made the victims' families the happiest.
The second happiest aren't Song Jiangguo or Qin Yong, but definitely the colleagues in the municipal bureau's Publicity Departnt.
"Fingerprint Identification Expert Clears Old Cases."
"Our City's Fingerprint Identification and Analysis Expert Successfully Solves Seven Cold Murder Cases!"
"The Legendary Story of the Fingerprint Identification Expert."
"A Day with the Fingerprint Identification and Analysis Expert."
Before the eting, colleagues from the Publicity Departnt had already written the news headlines.
Next, according to the usual procedures, Lu Chuan would deliver a guest lecture prepared by soone unknown using a pre-prepared PPT.
Talking about struggle, dedication, and a thing or two about fingerprint identification.
Even more straightforwardly, it could encourage, "If it's you, you can do it too."
The reality is, if it were you, you really couldn't.
Having been dealt with all afternoon, Lu Chuan made a hasty escape.
On the way back to the Criminal Investigation Team, Lu Chuan felt a lingering fear.
"Captain Qin, let be clear, I'm fine with fingerprint identification, but if they try to make do more interviews... I'll apply for a transfer!"
"What transfer, don't worry, I'll tell Director Wang they absolutely won't bother our team."
"No promotional talks either."
"What promotional talks, don't worry, I'll tell Director Wang you won't be doing that either."
Qin Yong answered earnestly, repeating word-for-word.
Of course, he was serious, more fingerprint analysis and identification is better than talks.
Of course, human energy is limited.
Especially for fingerprint identification and analysis, nobody can perform endlessly without rest.
Working nonstop for three to five days is feasible, but over ti, one's spirit collapses.
For instance, the fingerprint battles organized by the provincial departnt really deliver significant results each ti.
But why don't they conduct them frequently and only annually?
Because there are only so many experts at the provincial level.
Holding one battle and overworking a little is okay.
Doing it every day would be unbearable.
Like milking a cow, there's only so much good stuff, once exhausted there's nothing left, no matter how much you push.
If not careful, you might even overdo it and damage sothing.
Returning to the Criminal Investigation Team, Lu Chuan received a warm welco.
Qin Yong also had a good idea.
He arranged for Forensic Doctor Shen Yan to prepare flowers for Lu Chuan.
At the entrance of the team office building, except for mbers of Action Group Two who were on a mission, Sun Jun, Wang Changjiang, Liu Guodong, and others were all there.
"Attention, everyone!"
"Applaud!"
A neatly aligned team was already in formation, with Shen Yan in the middle presenting the flowers.
The applause grew louder.
"Welco ho, hero!"
