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

A team of seven or eight fully armed police officers rushed in. The leader, Di Yifan, scanned the area with sharp eyes and finally locked his gaze on Jiang Xia.

"Jiang Xia, come with us."

Di Yifan's voice was as cold as ice.

The entire office fell silent instantly; everyone was stunned.

Li Ya suddenly grabbed her husband's arm, her knuckles turning white.

"What are you doing? Hasn't the case already been solved?"

"New evidence."

Di Yifan waved the search warrant in his hand.

"The footprints at the scene perfectly match Jiangxia's shoes."

Luo Fei frowned and stepped forward.

"Captain Di, this is against the rules. Footprints alone are insufficient."

"Captain Luo."

Di Yifan interrupted him, a cold smile playing on his lips.

"We've applied for all the necessary permits. So why can't we touch the people in Team Two?"

Chen Xuanran was so angry that his face turned pale.

"You're settling a personal score! Just because our second team had a higher case-solving rate than yours last month!"

Di Yifan ignored him completely, and with a wave of his hand, two police officers stepped forward and restrained Jiang Xia.

Jiang Xia struggled for a moment.

"I left home at four o'clock, and the deceased died at two o'clock! The time doesn't match at all!"

"Let's save those words for the interrogation room."

Di Yifan said coldly.

Luo Fei watched as Jiang Xia was taken away, while Li Ya slumped into a chair, her face deathly pale.

The entire second team stared angrily at the departing figure.

"Captain Luo, we can't just stand by and watch!"

Deng Yunzhou slammed his fist on the table.

Luo Fei.

"Don't rush. Chen Xuanran, go and check on the situation. The rest of you go back and rest, we'll meet again this afternoon."

The crowd reluctantly dispersed, but Luo Fei did not leave.

He stood by the window, watching Jiang Xia being escorted into a police car downstairs, his brows furrowed.

His intuition told him that things weren't that simple.

At 2 p.m., the atmosphere in the meeting room was heavy.

Chen Xuanran hurriedly pushed the door open and came in.

"Team Leader Luo, Team One obtained a search warrant and found a knife at Li Ya's house. It matches the victim's wounds!"

"what?"

Deng Yunzhou suddenly stood up.

"This is impossible!"

"There was no blood or DNA on the knife."

Chen Xuanran added.

"But Di Yifan insisted on detaining Jiang Xia for 24 hours."

Luo Fei tapped his fingers lightly on the table.

"The video only proves that Jiang Xia left the house at 4 PM, but it doesn't prove he wasn't there at 2 PM. What if he left the community through another exit?"

"Then why did he go out at four o'clock to leave a picture? Isn't that unnecessary?"

Deng Yunzhou countered with a question.

Luo Fei's eyes gleamed.

“That’s exactly where the doubt lies. Let’s go check out Shanshui International.”

Security was tight at the Shanshui International residential complex. Luo Fei and Chen Xuanran looked around and found that there were no other exits except the main gate.

"strangeness."

Luo Fei muttered to himself.

"If Jiang Xia wants to leave, he can only go through the main gate. But the surveillance footage shows that he only appeared for the first time at four o'clock."

Suddenly, Luo Fei's eyes lit up.

"Wait, I have a way to confirm."

He strode toward the police car, and Chen Xuanran jogged after him.

"Captain Luo, what's wrong?"

"Back at the station, I want to interrogate Jiang Xia myself."

In the interrogation room, Jiang Xia looked haggard, but her eyes remained firm.

"I told you, I didn't kill anyone!"

Luo Fei gestured for the recorder to leave, leaving only himself and Jiang Xia behind.

He narrowed his eyes slightly.
"Genius Eye" activated.

Four semi-transparent characters appeared above Jiangxia's head.

[Insult to a corpse], next to which is the number 2.

Luo Fei's heart skipped a beat.

The fact that it's not "murder" and the sin value is only 2 indicates that...
He focused his mind, and the branch information appeared before his eyes.

On the day of the incident, Zhu Mingwei's body was injured and thrown off a cliff.

Luo Fei suddenly stood up, startling Jiang Xia.

"Jiang Xia."

Luo Fei's voice was deep.

Do you know Zhu Mingwei?

Jiangxia's pupils contracted slightly.

"I don't know him."

"Then why did you throw his body off the cliff?"

Jiang Xia's face turned deathly pale instantly, and her lips trembled as she was unable to speak.

Luo Fei took a step closer.

"You're not the murderer, but you know who the murderer is. You're protecting that person, aren't you?"

Jiangxia's defenses collapsed. He lowered his head, his shoulders trembling slightly.

"I can't say."

Luo Fei sat back down in his chair, his tone softening.

“I understand you want to protect someone. But this is a murder case, and hiding it will only make things worse.”

Jiang Xia raised her head, tears welling in her eyes.

"She has suffered too much."

"she?"

Luo Fei keenly grasped this pronoun.

"Was it Zhu Mingwei and his group back then?"

Jiang Xia closed his eyes in pain and nodded.

Luo Fei's brain was working at lightning speed.

A gang rape case from years ago, four perpetrators, are now being killed one by one in revenge? But why is Jiang Xia involved?

"This girl...isn't Li Ya?"

Luo Fei asked tentatively.

Jiangxia suddenly looked up.

"No! Li Ya knows nothing!"

Luo Fei nodded, already having made his judgment.

He got up and left the interrogation room, where he ran into Chen Xuanran, who was anxiously waiting in the corridor.

"Let go."

Luo Fei said briefly.

"What? But what about Team One?"

“I’ll go explain to the bureau chief. Jiang Xia isn’t the murderer, but he did conceal some things.”

Half an hour later, Jiang Xia was released.

Li Ya rushed forward and hugged her husband tightly, tears streaming down her face.

Luo Fei stood not far away, watching their departing figures, lost in thought.

In the conference room, all members of Team Two were present.

Luo Fei stood in front of the whiteboard, which was covered with photos and clues related to the case.

"Jiang Xia is not the murderer."

Luo Fei got straight to the point.

"But he did go to the scene and tampered with the body."

Deng Yunzhou frowned.

"What do you mean?"

"He added to the knife wounds on the victim's body and then threw the body off the cliff."

Luo Fei pointed to the photo on the whiteboard.

"The aim was to confuse the autopsy and make us mistakenly believe that the murderer was male."

Chen Xuanran gasped.

"So the real culprit is a woman?"

"She is very likely a victim of the gang rape case."

Luo Fei nodded.

"Jiang Xia knows her and is protecting her."

"Could it be Li Ya?" someone asked in a low voice.

Luo Fei shook his head.

“I checked, Li Ya has no sin value.”

He paused, then realized he had let something slip and quickly added something else.

"I mean, Li Ya's background check was very clean."

"Now what?"

Deng Yunzhou asked.

Luo Fei wrote several names on the whiteboard.

"Focus on investigating all women around Jiang Xia, especially those closely related to him. Li Ya will temporarily step aside from this case and go home to rest."

Luo Fei tapped his fingers lightly on the table, his brows furrowed.

The office was filled with the mixed smell of coffee and instant noodles. The whiteboard on the wall was covered with case clues, but all the arrows eventually pointed to a dead end. Jiang Xia.

"That doesn't make sense."

Luo Fei suddenly spoke, his voice exceptionally clear in the quiet office.

“Jiang Xia was definitely the person who assisted in handling the body at the scene, but our investigation shows that he was almost completely isolated from the outside world.”

Chen Xuanran looked up from the computer and rubbed his sore eyes.

"Boss, we checked his call records, social media accounts, travel history for three months, and even his food delivery orders."

This guy is practically a hermit; all he does is work and go home. He doesn't even have a single decent friend.

Deng Yunzhou pushed up his glasses, the lenses reflecting the blue light from the computer screen.

"What's even stranger is that his computer's security level is ridiculously high. I tried several methods but couldn't hack into it. This is unlike a normal computer."

Luo Fei stood up, walked to the whiteboard, picked up a red marker, and drew a circle around Jiang Xia's name.

“A simple life doesn’t equate to innocence. Let’s look at it another way: just because Jiang Xia hasn’t been in contact with other women recently doesn’t mean he’s only ever known Li Ya.”

"What the boss means is..."

Chen Xuanran's eyes lit up.

"Ex-girlfriend, or online friend."

Luo Fei wrote these two keywords on the whiteboard.

"Let's assume the girl who was gang-raped was Jiang Xia's ex-girlfriend, or someone he met online. She told Jiang Xia about her ordeal, and for some reason, Jiang Xia decided to help her."

Deng Yunzhou whistled.

"This explains why he would risk helping to dispose of the body. Emotional factors are often more likely to drive people to commit crimes than self-interest."

"Yunzhou, continue trying to hack into his computer, but don't alert him."

Luo Fei turned to Chen Xuanran.

“Investigate Jiang Xia’s romantic history, especially during his university years. He’s not a local, so we need to investigate his hometown as well.”

Chen Xuanran typed rapidly on the keyboard.

"We're already checking his academic records. Wait a minute. This shows that he used to be a top student at the school, but he suddenly dropped out and didn't even take the high school entrance exam."

Luo Fei's eyes gleamed.

"Timing is crucial. Investigate what happened the year he dropped out of school."

Three days later, the investigation still had not made any breakthroughs.

Jiangxia's past is as clean as if it had been carefully wiped clean; not even a single group photo of classmates can be found.

Deng Yunzhou's hacking attempts also repeatedly failed.

"This guy is definitely suspicious."

Deng Yunzhou scratched his hair in frustration.

“His firewall setup is incredibly professional; I suspect he has received professional training.”

Luo Fei pondered for a moment.

“Since remote access doesn’t work, we’ll try physical contact. Yunzhou, prepare a USB drive with remote monitoring code; we need to physically access his computer.”

"Boss, this isn't in compliance with regulations."

Chen Xuanran whispered a reminder.

"So we need a perfect excuse."

Luo Fei revealed a sly smile.

"Let Jiang Xia come to the police station to cooperate with the investigation, and we'll take the opportunity to go to his house."

The plan was implemented quickly.

The next morning, a phone call came to Jiang Xia's company, claiming that he needed help identifying surveillance footage of a traffic accident.

Meanwhile, Luo Fei, Deng Yunzhou, and Chen Xuanran were already standing at the door of Jiangxia's house.

The doorbell rang three times before the door opened.

Li Ya was wearing loungewear, her hair casually tied back, and she was clearly taken aback when she saw the three of them.

"Officer Luo? What's going on here?"

"Ms. Li, I'm sorry to bother you."

Luo Fei gave a professional smile.

"We have some additional questions about the case that we would like to ask you."

Li Ya's gaze swept between the three people before she finally stepped aside and opened the door.

"Please come in. Ziqi, the police officers are here."

The little boy ran over from the living room and his eyes lit up when he saw Chen Xuanran.

"Auntie Toy!"

Chen Xuanran squatted down and took out an exquisite car model from his bag.

"Ziqi, you still remember me? Look, Auntie brought you a new toy."

Wow! It's the same one Dad bought!

Jiang Ziqi excitedly took the toy, skillfully pressed the button on the bottom, and the car immediately started roaring with the sound of an engine.

Chen Xuanran's smile froze for a moment, and he exchanged a glance with Luo Fei. This limited edition model had only recently been released, and ordinary families rarely bought it for their children.

Li Ya seemed not to notice this detail and gestured for everyone to sit down.

"Jiang Xia was just called to the police station by your colleagues, didn't you know?"

"Oh, it might be a case from another team."

Luo Fei answered naturally.

"Our investigations are going in different directions, but we should be making progress soon."

"Would you like something to drink? Coffee or tea?"

Li Ya turned and walked towards the kitchen.

"Tea is fine, thank you."

Luo Fei's gaze followed Li Ya, noticing that her right leg seemed to have some difficulty walking.

Deng Yunzhou pretended to be curious and looked around.

"Your home is decorated with great taste. What does Mr. Jiang do for a living?"

"I don't really understand the IT industry."

Li Ya's voice came from the kitchen, accompanied by the sound of water boiling.

He said it was just about writing code.

Luo Fei got up and casually walked towards the kitchen.

"Do you need help?"

The kitchen was spacious and bright, but Luo Fei immediately noticed something unusual. The double-bowl laundry sink had clearly not been used for a long time, with a thin layer of dust on its surface.

On the table next to it was a set of valuable Japanese handmade knives, gleaming coldly in the sunlight.

"This set of knives is very professional."

Luo Fei feigned admiration.

Li Ya didn't even turn her head.

"It was a wedding gift from a friend, but I've never used it."

"Is the laundry sink no longer needed?"

Luo Fei continued to probe.

"The downstairs neighbor said there's a leak, but they're too lazy to fix it."

Li Ya's tone suddenly became stiff.

"Everyone uses washing machines now."

Luo Fei nodded, his gaze sweeping over every corner of the kitchen.

Jiang Ziqi's painting and class schedule are pasted on the refrigerator door, and a half-finished cup of milk is on the kitchen counter.

Everything seemed so normal, yet there was an inexplicable sense of unease about it.

Back in the living room, Deng Yunzhou was playing with Jiang Ziqi's new toys, while Chen Xuanran pretended to be interested in the photos on the bookshelf.

"Ms. Li."

Luo Fei accepted the tea that Li Ya offered him.

"Can I use the restroom?"

"Turn left at the end of the corridor."

Li Ya pointed in the direction.

After Luo Fei left, Deng Yunzhou took the opportunity to speak.

"Does Mr. Jiang usually work from home? May I visit his study? I'm also very interested in IT."

Li Ya hesitated for a moment.

"Sure, but please don't touch his computer. He said he has an important project to work on."

The moment Deng Yunzhou pushed open the study door, a faint woody scent mixed with the metallic smell unique to electronic devices wafted out.

He raised an eyebrow. The study was at least a third smaller than he had imagined, but every inch of space was used to its fullest potential.

"Tsk, this guy is a homebody."

Deng Yunzhou muttered to himself, his gaze sweeping over the two bookshelves that were crammed full.

The one on the left is clearly a work-related book, with various programming manuals and psychology books neatly arranged; the one on the right is piled with comics and game guides, with a complete set of "Dragon Ball" in the most conspicuous position.

Li Ya stood in the doorway, her fingers nervously twisting together. (End of Chapter)
