Captain Lu was aloof again today.

Chapter 22 Evidence
Just as Ye Chen was about to say something more, a soothing piano melody suddenly began to play.

Wei Qingsong pointed to his phone: "I'm sorry, as you can see, I'm really busy with a lot of work at the bureau."

Ye Chen smiled calmly: "Then you go ahead and get busy, I won't bother you anymore."

Wei Qingsong forced a smile.

Now you know not to bother her, why didn't you realize this sooner?
She turned around, and the smile on her face instantly vanished.

Fortunately, the call came in time; otherwise, Ye Chen might have pestered her for who knows how long.

This person is like a ticking time bomb; it's best to stay away from him.

After the call connected, Wei Qingsong remembered to glance at the caller ID; it was an unfamiliar number.

She was startled and subconsciously thought of Bailiwan.

After hesitating for a moment, I put the receiver to my ear.

"Sister Wei, come back quickly, we have a lead!" Chen Jin's overjoyed voice came through the receiver.

Wei Qingsong breathed a sigh of relief: "I understand. I'm on the nearby commercial street. I'll be back in ten minutes."

After hanging up the phone, Wei Qingsong closed his eyes briefly, took a few deep breaths to clear his mind of the jumbled thoughts, and then headed towards the Municipal Bureau.

It seems you really can't make promises lightly. She didn't even check the caller ID before telling Ye Chen that she was busy, and unexpectedly, her prediction came true.

If her mouth could always be this effective, she would definitely say "Lu Jingming loves me" every day.

At the Municipal Public Security Bureau, Chen Jin put down his phone, cautiously glancing at the aloof and elegant man beside him, and muttered, "You saved Sister Wei's number, why don't you call her yourself?"

To be honest, Wei Qingsong hasn't exchanged contact information with the other members of the team yet. Her resume lists a number she used overseas, and it's unclear where Lu Jingming got her phone number from.

As Chen Jin was still pondering to himself, he noticed Lu Jingming casting an unfriendly glance his way.

"Did I make you feel wronged by asking you to make a phone call?"

He froze instantly, shaking his head like a rattle-drum: "No, no, I'm very happy to serve Captain Lu and Sister Wei."

It's just being a mouthpiece, what's the big deal?

It's just a little tiff, right? He pretends not to know anything about it.

Although he wasn't as quick-witted as Captain Lu and Sister Wei, he still had that much awareness.

Lu Jingming gave a cold snort, his eyes filled with an unfathomable darkness.

When Wei Qingsong returned, he saw him sitting at the conference table, a black pen spinning rapidly between his slender fingers. It was an ordinary pen, but in his hands, it seemed to have inexplicably gained value and become noble and elegant.

He lowered his head slightly, examining the documents in his hand. The daylight was dim, but Wei Qingsong felt that his handsome profile seemed to radiate a starlight-like glow, shining brightly.

His cold and austere face was sharply defined, with hard and stern lines. He had a high nose bridge, thin lips, and sword-like eyebrows that slanted upwards to his temples. His eyes were dark, bright, and deep, like a vast starry sky, profound and mysterious, as if they contained the universe and could encompass all things.

But in those all-encompassing eyes, there was none for her.

Hearing the door open, his cold eyes swept over her quickly.

"Sit down." Then, he tilted his head and gestured to Xiao Song, "Speak."

His voice was deep and carried an air of authority.

After Wei Qingsong sat down, Xiao Song excitedly handed her the documents in his hand.

Although he tried his best to suppress his emotions, Wei Qingsong could still see his ecstasy from his radiant face.

She glanced down at the documents; it seemed that Xiao Song, as a newcomer, was about to make a great contribution this time.

“Captain Lu asked me to visit Li Yundong’s parents’ home. When I got there, I found that there were several red-light districts in that area. Generally speaking, there are many guesthouses in such places, and some can even be checked in without an ID card. So I asked from house to house along that street, and I actually found someone who knew Li Yundong!”

Xiao Song's voice was trembling, not from fear, but from being too excited.

"The owner of the Red Star Guesthouse said that Li Yundong would take a young and beautiful woman to a hotel every weekend. I showed him a photo to confirm that it was the deceased Yang Yan."

Chen Jin added: "Just now, the traffic management bureau received our request for assistance and sent us surveillance footage from several nearby streets. On the evening of the 18th, Li Yundong and the deceased Yang Yan appeared together in the surveillance footage. The two were arm in arm, looking very close, and entered the guesthouse while chatting and laughing."

He turned the laptop around and played a surveillance video.

Wei Qingsong glanced at the time; there were still 16 hours left.

Once more conclusive physical evidence is found, Li Yundong can be convicted.

With today's advanced criminal investigation technology, no matter how vicious the perpetrator is, no matter how eloquently they try to exonerate themselves, the irrefutable evidence will ultimately prevent them from escaping the punishment of the law.

Racing against time, with no time to lose, the technicians immediately rushed to the scene to conduct an inspection.

An hour later, the police obtained CCTV footage of Li Yundong leaving the guesthouse with his suitcase on the morning of the 19th. Since then, Yang Yan has never been seen again.

The guesthouse owner confessed that he was drunk that day and knew nothing about it.

Two hours later, technicians detected a luminol reaction in the guesthouse's restroom and collected multiple fingerprints at the scene. However, due to the special nature of the guesthouse, their reference value is questionable.

However, it is certain that the Red Star Guesthouse was the primary crime scene.

No remaining body parts of the deceased Yang Yan or the murder weapon were found at the guesthouse. The police immediately launched a large-scale carpet search centered on the Hongxing Guesthouse, covering a radius of five to ten kilometers.

Time was of the essence, and after six hours, good news finally came back from the scene!

"Captain Lu, we found the victim's head, a hammer, and a blood-stained garment in the sewer well of the residential area where Li Yundong's parents live."

An investigation revealed that a week prior, the manhole cover in the residential complex where Li Yundong's parents lived had been left wide open for maintenance. The complex is old and located next to a garbage dump, so no one noticed the odor.

In the conference room, which was shrouded in gloom, everyone breathed a sigh of relief, and the gloom on Lu Jingming's face also completely disappeared.

"Well done, let's wrap up."

"Yes!"

Young and fearless, Xiao Song was the first to speak up, exclaiming, "I really didn't expect that these pieces of evidence could actually be found in the neighborhood where Li Yundong's parents live."

He originally thought Li Yundong would throw these things into the sea and end it all.

Chen Jin looked at Wei Qingsong with both admiration and surprise: "Sister Wei, how did you come up with the idea of ​​looking for clues near Li Yundong's parents' residence?"

Although Captain Lu outwardly showed great disdain for Wei Qingsong's criminal mentality, after hearing Wei Qingsong's words in the interrogation room, Lu Jingming immediately had Xiao Song investigate; otherwise, they wouldn't have found the evidence so quickly.

Tangzhou is not a small city; trying to find someone's information in all the hotels and guesthouses in the city is like finding a needle in a haystack.

Moreover, there are many others like the Red Star Guesthouse that slipped through the net.

While criminal psychology may not be able to pinpoint a target through simple reasoning, it can narrow down the search area, saving them a significant amount of manpower, resources, and time.

Solving murder cases requires that every minute and second be accounted for.

Perhaps this is the allure of criminal psychology.
