I'm not a genius detective

Chapter 113 Yin Yunliang

meeting room.

Han Ling vaguely grasped something, but couldn't quite put it into words yet.

While investigation and counter-investigation are interconnected to some extent, there are still significant differences. To break through a case quickly requires a high level of investigative skill and experience; otherwise, traditional criminal investigation methods must be used to investigate bit by bit.

The portrait was completed, and Lin Yusheng delivered it to the conference room.

“Captain Ji, I’ll draw exactly what the eyewitnesses say, but the problem is…” Lin Yusheng paused, then continued, “The problem is that they can’t verify the accuracy of the portrait, which makes things more difficult.”

Ji Bowei took the portrait and looked at it. It was a middle-aged man in his fifties with medium-length hair and a beard, exactly as described by the four taxi drivers.

Judging from his basic characteristics alone, Lin Yusheng's skill level is quite high.

But basic features are just basic features; whether someone looks alike depends mainly on their facial features.

"Did they say it looks like it?" Ji Bowei asked.

Lin Yusheng: "They only said it looked like him, Captain Ji. It's not enough. An eyewitness has to be able to recognize him at a glance. Due to memory loss, this is all I can do."

Ji Bowei politely replied, "It's already very good, thank you."

This wasn't because Lin Yusheng lacked ability, but because objective conditions didn't allow it.

Lin Yusheng: "Then I'll head back to the Municipal Bureau first. If you find any new witnesses in the future, please contact me anytime. Every minor adjustment will increase the accuracy of the profile."

Ji Bowei nodded: "Okay, I'll take you."

He personally escorted Lin Yusheng out of the branch office, and then quickly returned to the conference room to assign tasks.

Within three days, he will gather forces to conduct a comprehensive review of surveillance footage near the urban villages, and he will request support from other squadrons to expedite the process.

After three days of fruitless investigation, half of the police force was deployed to visit rural vendors and markets to search for anyone selling arsenic or who had recently sold arsenic.

Try your best to make a breakthrough within five days.

"Five days?"

The group exchanged glances. Five days was a very short time for investigating a murder case. On average, the time to solve a murder case nationwide was between ten days and a month.

Some cases are solved on the spot, some within 24 hours, and some take months or even years to resolve, depending on the region, police resources, and the complexity of the case.

In short, five days is probably not enough under normal circumstances.

Hu Lihui looked at Ji Bowen: "Captain Ji, the provincial department's inspection and guidance team will arrive in five days?"

Ji Bowei hesitated for a moment, then nodded and said, "Yes, we'll be there in five days. Don't feel pressured, everyone. Which city doesn't have murder cases? Just do your best. If you can solve it, great. If you can't, we've still fulfilled our duty."

Inspection and guidance team.

Everyone felt a chill run down their spines; those words sounded rather frightening.

"It's just an inspection and guidance, mainly handled by the Municipal Bureau, it doesn't really concern us." Ji Bowei reassured everyone, "Five days is not a deadline. Even if we can't solve the case within five days, it won't have any impact."

All the officers understood that Ji Bowei meant to try to leave a good impression on the patrol guidance team. Having solved a case on the table was better than having one that hadn't been solved yet.

One of the officers asked curiously, "Captain Ji, who's the team leader?"

Without a doubt, it must be a high-ranking official in the provincial department, either holding a high position or being a senior expert.

This was no secret; Ji Bowen had informed him beforehand: "Yin Yunliang."

Upon hearing the name, the conference room stirred. The familiar police officers whispered among themselves, their faces displaying a complex mix of anticipation, excitement, and reverence.

When I was in police academy, the name Yin Yunliang was quite familiar to everyone, and most people had seen him and attended his public lectures.

"Hey, Yin Yunliang is coming." Tong Feng nudged Han Ling, who rarely showed any interest in a particular person.

Han Ling didn't react much: "I heard it."

This person is in my new memory.

Yin Yunliang, Director and Chief Expert of the Criminal Psychology Research Office of the Jiangyuan Provincial Public Security Department, is a Level 2 Police Inspector and is under 50 years old.

My impression of this person is that he is always smiling, but he has a calm demeanor, sharp eyes, and extremely strong observation and insight. He usually dresses simply, but a sense of oppression always comes over him invisibly.

During that open class, the entire room was completely silent. The students didn't dare to breathe, and some even stammered when asking questions.

This man's experience in criminal investigation of major cases is almost unmatched in the entire Jiangyuan Province. All the criminal investigation team leaders, including the chief criminal investigation officer, pale in comparison to him.

Since it was Yin Yunliang who came, the word "inspection" and "guidance" should only be "guidance".

"Alright, enough chit-chat." Ji Bowei gestured for everyone to be quiet. "Now, let's immediately begin the investigation of surveillance footage. Every shop and residence with cameras must be covered. Captain Hu will arrange the area division. Also, everyone should have a sketch of the suspect. When checking the surveillance footage, we'll also take people in for questioning."

All officers: "Yes, sir!"

A massive net has been cast over the urban village where the crime occurred. The branch bureau and the local police station have joined forces to conduct a large-scale investigation of known suspects.

This investigation lasted for three days.

To be honest, the result was beyond the expectations of the task force. Before the investigation, they thought that even if they couldn't find the face in the surveillance footage, they should at least get some information from the back and side, but they found nothing.

This could be due to a lack of surveillance or because the suspect possesses certain counter-surveillance capabilities.

As long as one is aware of the need to avoid surveillance, it is very easy to bypass the not-so-dense surveillance cameras near urban villages.

There are many surveillance cameras around Dai Bin's residential area, but since the suspect has confirmed that Dai Bin is temporarily staying in an urban village, it is impossible for him to reappear. Indeed, the investigation found nothing.

As planned, the investigation would shift to rural visits three days later, and Han Ling and Tong Feng were among them. There were many villages in the surrounding area, and vendors were rare on non-market days, so they could only visit the villages where there was a market that day, conducting a thorough search and investigation throughout the day.

"This isn't a sustainable solution." Han Ling's motivation began to wane the next day. "How many large markets are there around Qingchang City? Including the county seat, there must be at least five hundred. How long will this search take?"

Tong Feng: "It's only the second day, why are you in such a hurry? Captain Hu investigated Cui Henian's case for twelve years. How many days is twelve years? More than four thousand days."

Han Ling: "What I mean is... never mind, let's investigate, let's listen to the captain."

There really isn't a good solution right now.

Three more days passed, and the task force held its routine meeting that evening.

The scope of the visits gradually expanded outwards, almost reaching the county towns and villages, and the monitoring on the other end did not stop either.

In theory, the suspect might appear at every rural market in Qingchang to buy arsenic, which is a relatively clear direction and should not be overlooked.

During the meeting, Ji Bowei mainly focused on encouragement and motivation, explaining that this was the job of criminal investigators, which involved wearing down the willpower of investigators in a monotonous environment.

"Get some rest tonight, meeting adjourned!"

Just as Ji Bowei finished speaking, a knock sounded on the door.

"Come in." Ji Bowei said subconsciously, turning his head to look.

The door opened, and a middle-aged man walked in with his hands behind his back. He glanced at Ji Bowei with a smile, then scanned all the police officers in the conference room before fixing his gaze on Han Ling.

Upon seeing this person, Ji Bowen almost didn't react. After a three-second pause, he quickly stood up and asked, "Director Yin, what brings you here so suddenly?"

Wow!

The other officers in the conference room also quickly stood up, their chairs scraping against the floor with a jumble of noise, their eyes filled with surprise and respect.

They didn't expect Yin Yunliang to appear at the branch office that night.

The other party arrived in Qingchang two days ago. They knew about this, but Yin Yunliang's main job was at the Municipal Bureau, so he shouldn't come to the branch bureau so easily.

It's impractical to go to all eight branch offices; if there's a real issue, the municipal bureau can relay the message.

Yin Yunliang smiled and said, "I just finished eating and strolled over. Is there... a case?"

Ji Bowei replied, "Yes, Director Yin, there is a case, a poisoning case. We have obtained some characteristics of the suspect and are currently conducting a large-scale investigation."

Upon hearing this, Yin Yunliang nodded and said, "After the investigation, it seems that the interpersonal relationships have been investigated, the motive for the murder is still unclear, and the suspect did not leave any investigative clues."

Ji Bowei nodded: "Yes."

Yin Yunliang: "May I see the case files and all the investigation materials?"

"Of course!" How could Ji Bowen refuse? "Director Yin, please have a seat. I'll tidy it up myself right away and put it in front of you in ten minutes!"

Yin Yunliang stood still and said, "Give me a private room, and later... have Han Ling bring it to me."

Ji Bowei was taken aback: "Huh? Oh, okay, okay, I'll arrange a room right away and have Han Ling send the documents over."

Yin Yunliang turned and left.

Ji Bowei gave the order, and Hu Lihui and Fang Zhou quickly followed to arrange a room for him.

Everyone was puzzled. The other party came to the branch office and specifically named Han Ling. Was they here for Han Ling?
Because of... those previous cases?

In the year since joining the force, Han Ling's work performance has indeed been outstanding. There has never been such an excellent new police officer before, which is to be expected.

"You know him?" Tong Feng asked enviously in a low voice.

Han Ling shook her head: "I don't know him. How would I know him? I've only attended his classes."

Tong Feng: "Okay, that must be a previous case. The credit was reported to the provincial department, which attracted Professor Yin's attention."

Han Ling: "Maybe."

Tong Feng's guess was completely correct this time, and that's why Yin Yunliang came here.

Inside the room, Hu Lihui and Fang Zhou left, leaving Yin Yunliang alone to wait quietly.

Two third-class merits within a year, and a first-class merit that the provincial department is discussing—this matter seems somewhat unbelievable to Yin Yunliang.

Therefore, taking advantage of his inspection and guidance trip to Qingchang, he wanted to meet this new police officer named Han Ling.

He accurately identified the murderer from the crowd and was awarded a third-class merit.

Just as the case was about to be closed, a hidden accomplice was apprehended, and the individual's third-class merit award had just been confirmed but had not yet been issued.

The case in Weijiazhuang Village is currently under discussion for a first-class merit award. Yin Yunliang has looked into it, and there shouldn't be any major problems.

From the police drills to now, he has mastered all of Han Ling's resume and thinks this young man... is quite interesting.

Moreover, from the perspective of criminal psychology, if Han Ling were not wearing this police uniform, he could sense the danger and had already made a detailed psychological profile of him.

Cold-blooded, yet possessing a strong sense of justice, his marksmanship suddenly became incredibly accurate after graduation, and he could effortlessly employ simple yet sophisticated counter-surveillance techniques in police drills... It was all very complex, and he couldn't see through it.

We must meet and have a good talk.

If possible, it wouldn't be a bad idea to train them.
