Solving the case: Combining the police dog's olfactory genes at the beginning

"I come here two or three times a week."

"Has he offended anyone? Especially someone who is married?"

Luo Fei asked.

The card players looked at each other and suddenly burst out laughing.

"That kid has offended a lot of people!"

A man missing a front tooth grinned.

"He specializes in seducing other men's wives; he's incredibly audacious."

"Tell me more specifically."

Luo Fei opened his notebook.

“Last month, he was flirting with Lao Zhang’s wife.”

The man with the front teeth lowered his voice.

"Old Zhang was so angry he almost grabbed a knife and chopped him."

Luo Fei wrote down the name "Old Zhang".

"Is there anyone else?"

"There are too many."

Old Liu chimed in.

"The wife of Manager Wang from the community property management company, and the owner of the supermarket at the street corner. That guy is a lecherous bastard."

Chen Xuanran frowned.

Why didn't you stop him?

The card players looked at each other, and finally Old Liu said awkwardly.

"What does this have to do with us? He asked for it."

Luo Fei asked a few more questions and wrote down all the women's names mentioned.

It was already dark when we left the mahjong parlor.

Luo Fei sat in the passenger seat, his fingers lightly tapping the edge of the car window, his brows furrowed.

Chen Xuanran gripped the steering wheel, glancing occasionally at his companion beside him.

"Old Luo, where are we going now?"

Chen Xuanran asked.

"Go to Li Changxing's house first, then go to Chen Guozhu's house."

Luo Fei said in a deep voice.

"Although these two people know each other, they have absolutely no connection with Zhu Mingwei. We have to find some connection between them."

Chen Xuanran nodded.

Do you think the killer committed random murders?

"Not quite like it."

Luo Fei shook his head.

"The three victims knew each other in pairs, but the third person had no connection with them at all, which is illogical. The murderer must have some kind of selection criteria."

The car drove into an upscale residential area, where Li Changxing's home was located.

Although Li Changxing, a second-generation rich kid, idled away his days, his family was indeed wealthy.

The two knocked on the door, and Li Changxing's mother greeted them with red eyes.

"Officer, my son may be playful, but he has definitely not offended anyone!"

Li's mother choked up as she spoke.

Luo Fei looked around and asked.

Who does Li Changxing usually associate with?

"Those fair-weather friends"

Li's mother sighed.

"Chen Guozhu is one, and there are a few others I'm not very familiar with."

Has he mentioned anything unusual lately? Or offended anyone?

Mother Li shook her head.

"No, he's never home, and I can't control him."

As Chen Xuanran left the Li family, he couldn't help but say.

"It seems that Li Changxing is a typical playboy who does nothing but eat, drink and have fun."

Luo Fei seemed to be deep in thought.

"Let's go find Chen Guozhu's family."

Chen Guozhu lives in an old residential area where the stairwells are covered with small advertisements.

The person who opened the door was Chen Guozhu's sister, who looked haggard.

"My brother is a hoodlum, but he doesn't deserve to die!"

She said, wiping away her tears.

Luo Fei got straight to the point.

How does Chen Guozhu support himself?

"he"

The older sister hesitated for a moment.

"I know it's not honorable to bring a prostitute along, but he doesn't have any other skills."

"Among the girls he brings along, are there any particularly famous ones? Or have they been involved in any recent disputes?"

The older sister shook her head.

“I don’t know about these things; he never tells me about them.”

Back in the car, Chen Xuanran suddenly slapped the steering wheel.

"Old Luo, do you think these three guys might all be clients of prostitutes?"

Luo Fei's eyes lit up.

"go on."

"Li Changxing is rich and loves to have fun, Chen Guozhu brings prostitutes, and although Zhu Mingwei looks honest, who knows what's going on?"

Chen Xuanran analyzed.

"The murderer might be a suitor of a prostitute, because these people patronized the women he liked."

"Revenge killing?"

Luo Fei continued the conversation.

"That's possible. But if that's the case, there are many potential victims. Some prostitutes see more than three clients a day."

Chen Xuanran nodded.

"The murderer may have chosen his targets through the women's phone contacts, so Zhu Mingwei wouldn't have been the last one."

Luo Fei pondered for a moment.

"Let's go back to the station first and see what the other teams have discovered."

The criminal investigation team's conference room was filled with smoke. When Luo Fei pushed the door open and entered, everyone stood up.

"Cheng Yunchuan, how are things on your end?"

Luo Fei asked.

Cheng Yunchuan, who was wearing black-rimmed glasses, pushed them up.

"Captain Luo, I've screened all the people who were close to the three deceased. Their photos are all on this USB drive, about a thousand people."

Luo Fei took the USB drive.

"Well done. Deng Yunzhou, did the surveillance footage find anything?"

Deng Yunzhou scratched his head.

"We've identified a few suspicious individuals, but further confirmation is needed. I've retrieved the surveillance footage from the vicinity of the three crime scenes and am reviewing it frame by frame."

"We can't rush it, but we can't delay it either."

Luo Fei said seriously.

"The perpetrator is very likely to strike again."

Forensic pathologist Zou Xiaowei pushed open the door and entered, holding a report in his hand.

"Captain Luo, we've made a new discovery."

Everyone fell silent.

Zou Xiaowei opened the report.

"The wounds of all three victims were caused by the same knife, but the angles and depths varied. The strangest thing is that the killer switched hands during the attack."

"Change of hands?"

Chen Xuanran asked in surprise.

"Yes, he stabbed me a few times with his left hand first, then switched to his right hand."

Zou Xiaowei explained.

"Moreover, all the wounds were on the front, indicating that the victims were all killed while facing the murderer."

The air in the conference room seemed to freeze.

The projector light shone on everyone's faces, making them appear as pale as paper.

All eyes were on Luo Fei, but he just stared silently at the computer screen, his fingers rapidly typing on the keyboard, dragging photos one by one onto the desktop.

"Captain Luo, what's wrong?" Chen Zhiqiang couldn't help but ask, his brows furrowed.

Luo Fei did not answer, but narrowed his eyes slightly, a sharp light shining deep in his pupils.

"Genius's Eye," activated!

In an instant, every detail in the photo was magnified infinitely in his eyes, even penetrating the surface to glimpse the hidden evil.

"found it."

Luo Fei suddenly spoke, his voice low and resolute.

He suddenly dragged a photo to the center of the screen and zoomed in.

The photo shows a middle-aged man wearing a floral shirt, with a greasy smile, but his eyes reveal a sinister look.

"Who is this person?"

Someone asked in a low voice.

Luo Fei sneered, tapped his fingers a few times on the keyboard, and a series of data immediately popped up on the screen.
Name: Zhang Debiao

[Age: 42 years old]

[Occupation: Unemployed, previously detained multiple times for gambling and prostitution]

[Sin Value: 238]

[Detailed record: On December 23, 2022, he, along with three fellow card players, raped a woman.]

"hiss"

A collective gasp filled the conference room.

"How is this possible?"

Chen Zhiqiang's eyes widened.

"Captain Luo, how can you tell all this directly from the photo?"

Luo Fei offered no explanation, only coldly stating, "He's not the murderer, but he could very well be the next victim."

"what?!"

Everyone was shocked.

"The first three victims were all his card-playing friends."

Luo Fei's gaze was sharp.

"And they were all involved in that rape case."

In an instant, everyone understood that this was a revenge plot!
"Arrest Zhang Debiao immediately!"

Luo Fei stood up abruptly, his voice resolute.

Chen Zhiqiang immediately stood up and led several team members out of the conference room.

Meanwhile, Team One and Team Three were also having intense discussions about the case in their respective conference rooms.

A meeting room for the team.

Di Yifan stood in front of the projector, his gaze sharp and his voice resounding.

"Brothers, this case has a very serious impact. The higher-ups have given a strict order: we must solve it as soon as possible! Our team cannot fall behind!"

"Yes!"

The team members responded in unison, their fighting spirit high.

Meeting room for Team Three.

Xu Guangwu personally oversaw the operation, tapping his fingers on the table with a serious tone.

"The killer's methods were extremely cruel, and his targets were clearly defined. We must grasp his patterns of action and get ahead of him!"

"understand!"

The three teams were eager and ready to try.

However, just as the two teams finished their meeting and were preparing to unleash their full potential...
In the corridor, Chen Zhiqiang led his team members through the crowd in a flurry of activity, heading straight for the elevator.

"Team Leader Chen, what's going on here?" one of the team members couldn't help but ask.

"Arrests!"

Chen Zhiqiang didn't turn his head, his tone urgent.

The three captains stared at the monitor screen, their faces showing expressions as if they had seen a ghost.

"This is impossible."

Team leader Wang Tiezhu slammed his fist on the table, causing a few drops of liquid to spill from the coffee cup.

"We investigated for a year without any leads, and he found the person in just twelve hours?"

Team leader Xu Guangwu's expression was uncertain, his eyes fixed on Luo Fei in the interrogation room on the screen.

That young man was only twenty-eight or twenty-nine years old, yet he had already made all the veteran detectives in the city bureau lose face.

"Old Xu, I heard Luo Fei used to be on your team?"

Second team leader Li Jianguo asked meaningfully.

Xu Guangwu's Adam's apple bobbed, and a bitter taste rose in his mouth.

He felt more than just regret; he wished he could travel back in time and strangle the version of himself who had let Luo Fei go.

Luo Fei had a 100% case-solving rate when he was in the Major Crimes Unit and was hailed as a "criminal investigation genius," but he was transferred to the Archives Department for some special reasons.

If it weren't for the difficulty of this serial murder case, the bureau chief wouldn't have granted special permission for his temporary transfer.

"I"

Xu Guangwu's voice sounded like it was being squeezed out from between his teeth.

"I should have married my daughter to him in the first place."

Inside the interrogation room, Luo Fei's slender fingers tapped lightly on the table, the rhythm like a countdown.

Zheng Hao, who was sitting opposite him, looked indifferent, even somewhat contemptuous.

"Officer, I already told you, it was just ice skating."

Zheng Hao shrugged.

"You can only detain me for a maximum of fifteen days, why are you being so serious?"

Luo Fei didn't reply, but instead pushed the three photos forward in a row.

The photo shows the mangled faces of three victims. The first died on Christmas Eve last year, the second on Valentine's Day this year, and the third last month.

What they had in common was that their genitals had been removed, and the procedure was clean and efficient, like a surgical operation.

"do you know it?"

Luo Fei's voice was very soft, but it made Zheng Hao's expression freeze instantly.

"I don't know him."

Zheng Hao's Adam's apple bobbed, and his eyes began to dart around.

Luo Fei leaned forward slightly, his black pupils like an abyss.

They're all dead. The same method, the same way.

His gaze shifted downwards meaningfully.

"Castration".

Fine beads of sweat appeared on Zheng Hao's forehead, and his fingers unconsciously twisted together.

Luo Fei knew he had hit a nerve.

"December 23, 2022, the eve of Christmas Eve."

Luo Fei's voice was like an ice blade.

What did the four of you do?

In the monitoring room, the three team leaders held their breath simultaneously.

"Is he faking a confession?"

Wang Tiezhu frowned.

“We checked the social circles of the three deceased, and there was absolutely no overlap.”

Xu Guangwu stared intently at Zheng Hao's reaction. The poisonous insect's face had turned deathly pale.

Inside the interrogation room, Zheng Hao suddenly stood up.

"I need a lawyer! This is a frame-up!"

Luo Fei calmly leaned back in his chair.

“Sit down. The evidence against you for drug use is conclusive. I can send you to a rehab center anytime.”

He paused.

"But that's not what I care about."

Zheng Hao's legs began to tremble, but he eventually sat back down.

"listen."

Luo Fei's voice suddenly softened, but it was even more chilling.

"The killer has already murdered three people, and his methods are becoming more and more sophisticated each time. Do you think he will let a fourth go?"

Zheng Hao's pupils suddenly contracted.

"I'll let you go."

Luo Fei suddenly said.

"But remember, the killer is watching you from the shadows."

Zheng Hao couldn't believe his ears.

"You...you're going to let me go?"

Luo Fei pressed the communicator on the table.

"Captain Chen, take him to finish giving his statement, then release him."

The monitoring room erupted in chaos.

"Is he crazy?"

Li Jianguo slammed his fist on the table and stood up.

"The suspect we finally found!"

Xu Guangwu, however, seemed to be deep in thought.

"Luo Fei never does anything in vain."

Ten minutes later, Chen Zhiqiang pushed open the door to the monitoring room, his face full of confusion.

"Luo Fei, what exactly are you planning? That kid is clearly suspicious!"

Luo Fei was organizing the documents on the table without looking up.

"Where's the evidence?"

Chen Zhiqiang was speechless.

Indeed, they had no direct evidence to prove that Zheng Hao was involved in the murder.

"Without evidence, he can be detained for a maximum of fifteen days."

Luo Fei finally raised his head, his eyes filled with cold light.

"Why not let him out as bait?"

"Bait?"

The three captains spoke in unison.

Luo Fei nodded.

"The murderer has already killed three people, but has not yet made a move against Zheng Hao. There must be a reason."

He turned to Xu Guangwu.

"Captain Xu, I need you to send someone to monitor Zheng Hao 24 hours a day."

Xu Guangwu immediately straightened his back.

"no problem!"

At that moment, he seemed to see again the genius detective who led the major crimes unit to solve countless major cases.

That capable assistant he once had but lost.

"in addition."

Luo Fei continued.

“We need to check all the police reports filed on the evening of December 23, 2022, especially those involving sexual assault.”

Chen Zhiqiang frowned.

"There is no relevant record in the system."

"So it's even more suspicious."

Luo Fei's eyes sharpened.

"Four men gang-raped a girl, but she didn't call the police. Either she was threatened, or..."

"She has other ways of taking revenge."

Xu Guangwu picked up where he left off and suddenly understood Luo Fei's line of thought.

Luo Fei nodded.

"The murderer is likely a relative, lover, or secret admirer of the girl. After learning the truth, he decided to seek justice in his own way."

Chen Zhiqiang gasped. (End of Chapter)
