No matter whether the person who ca that night is related to Wang Feng’s disappearance, considering the ti of Wang Feng’s disappearance, this person should be the last one to see Wang Feng.
This ti, Lu Chuan focused on the slippers, collecting so residues inside. Yang Lin didn’t question this. Since the person wore slippers, it’s highly possible they left so skin flakes or hair inside.
"Is this for DNA analysis?"
Lu Chuan nodded: "Wang Feng has been quite clean since university; he never wore others’ slippers, so the slippers at his house should be different for guests and himself.
In the past two years of work, Yang Lin and Lu Chuan frequently t each other, along with Zhao Tianyu, often dining together.
Yang Lin had long known that the work of the police station is completely different from that of the criminal investigation team—different nature, different experiences, everything is different.
In a grassroots police station, similar to the work Lu Chuan is doing now, it’s sothing the police station officers seldom do.
At most, they might encounter small theft cases, collect fingerprints in certain places, or take photos of obvious footprints, which counts as a relatively thorough cri scene investigation there.
But soone like Lu Chuan, who studies a doormat and a pair of slippers for ten to twenty minutes, or even half an hour, this doesn’t exist in grassroots police stations.
On one hand, there aren’t technical detectives with such abilities in grassroots police stations. On the other hand, the workload there is overwhelming, leaving no ti for such ticulous work.
Moreover, so work cannot be done as thoroughly as Lu Chuan does.
After all, the cases handled by the police station are like this: today Granny Zhang’s dog is missing, tomorrow Granny Li’s cat ran away, the day after Aunt Sun’s pet pig fell into the sewer.
Not to ntion situations like the Wang Family’s daughter-in-law scratching the Zhang Family’s daughter-in-law, or the Li Family’s daughter-in-law fighting with her husband, you na it.
Unlike now, where Lu Chuan is wearing white gloves and a mask, diligently searching for clues on the ground, looking exceptionally professional.
"Old Yang, since you’ve never done cri scene investigation before, put on your gloves, and don’t touch anything until I finish inspecting it," Lu Chuan said.
Yang Lin nodded: "Old Lu, I understand this stuff; I also formally graduated with a four-year degree, majoring in cri scene investigation, although I haven’t used it much in these two years, I’ve beco a bit rusty, lacking practical experience, but you can trust my basics."
Lu Chuan slapped his forehead, realizing he had forgotten.
"By the way, Old Yang, how’s it going at the police station? Have you thought about moving up?"
Yang Lin’s eyes brightened: "What do you an, which direction?"
"Of course, to get back to our main field—cri scene investigation. I can’t guarantee you’ll beco the station chief or deputy chief."
Cri scene investigation?
"So, the criminal investigation team needs people?"
The reason Yang Lin didn’t directly enter the criminal investigation team like Lu Chuan wasn’t because Lu Chuan had connections and Yang Lin didn’t.
In fact, according to the assignnt results of the exam back then, both Lu Chuan and Yang Lin should have joined the police station to work at the grassroots level.
However, due to Yang Lin’s ex-girlfriend’s wedding, where Lu Chuan arrested the groom, he gained rit, leading to the opportunity to join the cri scene investigation office of the criminal investigation team.
Of course, Qin Yong didn’t know at the ti that Lu Chuan’s family owned the Qiangsheng Group; otherwise, he wouldn’t have needed to make any achievents to directly transfer him—that would have been just money power!
Normally, when the criminal investigation team has vacancies, they mostly recruit through competitive hiring.
After all, the criminal investigation team deals with major cases. It’s best if new detectives have so work experience.
Therefore, the criminal investigation team often selects personnel for transfer, usually from grassroots police station criminal investigation teams.
For instance, in the Cri Scene Investigation Office, Old Bai is about to retire in over a year, and with a vacancy imminent, Liu Guodong can apply to Qin Yong to borrow soone temporarily from the police station or the criminal investigation team.
After more than a year of training, the transferred person could be well-prepared for the job at the criminal investigation team, and after Old Bai retires, the borrowed person can fill Old Bai’s position.
This echelon training managent model can effectively prevent job vacancies.
Lu Chuan nodded: "Our Old Bai is retiring in over a year; recently, my ntor is considering transferring personnel. How about it, interested?"
Yang Lin was stunned, then elated: "Damn, of course, I’m interested!"
"That’s the criminal investigation team!"
For any university student graduating from police school, possibly the most desired placent is the criminal investigation team.
But in reality, the grassroots police stations are most in need of people, and most police school graduates are assigned to grassroots police stations.
Now that Lu Chuan has this opportunity to go to the criminal investigation team, Yang Lin is certainly delighted.
Moreover, from another perspective, cri scene investigation holds significant importance in the criminal investigation team, but it doesn’t require many overti hours.
And to work together with old classmates, this opportunity is not to be missed!
"Alright, then I’ll talk to my ntor about it when I get back."
The idea of transferring soone is also on Liu Guodong’s mind; since Lu Chuan has a classmate who studied cri scene investigation, being professionally trained, Liu Guodong won’t oppose what Lu Chuan says.
"Damn, let treat you to a al! A feast!"
"Over a hundred per person!"
Lu Chuan: "..."
"Old Lu, what’s with that face? Your family is wealthy; we’re a working-class family. A hundred per person is already quite good."
"Besides, the salary at the police station is low; I don’t even make 4,000 yuan a month."
"Offering you a al costing over 200 yuan already stretches my limits."
As they chatted, the evidence collection work from the slippers was completed.
The left-hand side of the room was the living room, with a clean coffee table, having only a TV remote and a single packaging box.
Lu Chuan opened the food box, finding it empty, with only a layer of residue left; everything else was eaten.
"Was this the stir-fried rice cake?"
Yang Lin also noticed the packaging box on the coffee table, with stir-fried rice cake images printed on the outside.
Lu Chuan nodded: "The stir-fried rice cake inside was all eaten, but Wang Feng left the packaging box behind."
"Old Lu, Wang Feng ordered delivery at 11:30 pm; since he ate everything, it shows he and the other person stayed in the house for at least ten to twenty minutes."
"What about the ice cream?"
Lu Chuan looked down at the trash bag.
A red funnel-shaped piece of packaging lay quietly inside.
