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

"Mobile network IPs are dynamically assigned, however..."

A string of numbers and map coordinates popped up on the screen.

"According to base station data, this 'One Smile Can Captivate a City' account has been logged into locations throughout the past month."

His voice suddenly stopped.

"Shanshui International Community".

Luo Fei finished speaking for him, and then felt his heart skip a beat.

"The upscale residential area where Jiang Xia lives."

Silence fell over the office again.

Luo Fei stared at the flashing red dot on the map, which was less than two hundred meters away from Jiang Xia and Li Ya's apartment building.

"But how do you explain voice calls?"

Deng Yunzhou frowned.

"If Jiang Xia is impersonating a woman, how would she disguise her voice? Voice-changing software will show obvious distortion in real-time calls."

Luo Fei recalled Li Ya's gentle face and the fear that flashed in her eyes when she mentioned Jiang Xia.

"What if it's his wife?"

"Li Ya?"

Deng Yunzhou shook his head.

"There were no words above her head, so she's not the murderer."

"But she can help with conversation."

Luo Fei stood up and paced back and forth in the small office.

"Jiang Xia was in charge of killing, and she was in charge of fishing."

He suddenly stopped.

"Li Ya said she goes to bed at 10 p.m. every day, and these female netizens happen to be active after 10 p.m."

Deng Yunzhou's eyes widened.

"You mean"

"Check Zheng Hao's phone."

Luo Fei grabbed the car keys.

"If there are similar contacts, then that's the next one."

Before he could finish speaking, the walkie-talkie on the table suddenly rang.

"Captain Luo! A body has been found on the west side of Central Park; preliminary identification suggests it is Zheng Hao!"

Luo Fei stood at the crime scene, his brows furrowed.

The night wind carried the stench of blood, and his gaze was fixed on the clear size 40 shoe print on the ground.

"The murderer is quite audacious. The police just laid a massive dragnet, and he still dared to commit a crime against the odds?"

Luo Fei muttered to himself, his eyes filled with coldness.

Zou Xiaowei squatted to the side, carefully recording data with measuring tools, and looked up to say.

"Captain Luo, based on the depth of the shoe prints and the stride length, the murderer should be around 175cm tall, weigh around 65kg, and be male."

Luo Fei crouched down and gently traced the wound on the right abdomen of the deceased with his fingertips. The wound was neat and deep, and his technique was clean and efficient.

"The wounds are concentrated on the right abdomen, so the killer is most likely left-handed."

He narrowed his eyes.

"But strangely, the body was not moved this time."

In previous cases, the killers would deliberately adjust the position of the body, as if performing some kind of ritual.

But this time, the deceased lay in a pool of blood, without any trace of embellishment.

"The killer has changed their plans?"

Luo Fei murmured.

"Captain Luo, the surveillance footage is ready!"

Deng Yunzhou walked over quickly, holding a tablet in his hand.

Luo Fei took the tablet, and the screen displayed surveillance footage from the night of the incident at the Shanshui International residential complex.

At 5:13 a.m., a blurry figure hurriedly left through the side gate of the residential area.

"It's Jiangxia."

Deng Yunzhou pointed to the screen.

"But the time he left did not match the time of death estimated by the forensic doctor."

Luo Fei stared at the screen, his eyes sharp as knives.

"The shoe size and weight match, but the timing doesn't?"

He sneered.

"It's too much of a coincidence, it's like someone deliberately designed it."

Deng Yunzhou was taken aback.

"Captain Luo, are you saying... the murderer is misleading us?"

Luo Fei didn't answer, but suddenly asked a question.

What if the killer wasn't a man?

"what?"

Deng Yunzhou was stunned.

"If a left-handed woman wears size 40 men's shoes and adds some weight to her body, can she also leave footprints like these?"

Luo Fei said slowly.

Deng Yunzhou gasped.

"That's certainly possible!"

Luo Fei's eyes darkened.

“The murderer is playing us. She deliberately leads the clues to Jiang Xia, but Jiang Xia happens to have an alibi. As a result, the case is stuck in a vicious cycle.”

"Investigate! Get all the surveillance footage of people entering and leaving Shanshui International that night!"

In the monitoring room, Luo Fei and Deng Yunzhou stared intently at the screen.

The images flashed by frame by frame, and suddenly, a woman in a black trench coat caught Luo Fei's attention.

She kept her head down and walked quickly, but her posture was somewhat stiff, as if she was deliberately controlling something.

"stop!"

Luo Fei suddenly raised his hand.

The image freezes, and the figure of the woman in black becomes clearer.

"This woman's height and build are very similar to Li Ya's."

Deng Yunzhou frowned.

Luo Fei shook his head.

"Li Ya's walking posture is wrong. Her shoulders sway slightly when she walks. She's too stiff."

He pulled out Li Ya's photos for comparison and confirmed that she did not have any special markings on her head, a detail they had noticed when they were investigating suspects.

"It's not Li Ya."

Luo Fei said in a deep voice.

"Moreover, this woman never came out after entering the residential area."

Deng Yunzhou was taken aback.

"She's not a resident?"

Luo Fei sneered.

"If she was an outsider, then her target was very likely the deceased!"

The next morning, Cheng Yunchuan from the intelligence team rushed into the office.

"Captain Luo! We've found Zhang Weiwei's hospital records!"

Luo Fei looked up.

"What did you find?"

Cheng Yunchuan's expression was solemn.

"She went to the hospital a week before she died, and the test results showed that she was pregnant."

The office fell silent instantly.

"Pregnant?"

Deng Yunzhou's eyes widened.

"But she's always claimed to be single!"

Luo Fei's eyes darkened.

"That's the key."

He stood up and slowly paced around.

"A single woman's sudden pregnancy is either voluntary or forced."

Deng Yunzhou suddenly realized what was happening.

"Zhang Weiwei was sexually assaulted before, could the child be..."

Luo Fei stood downstairs at Zhang Weiwei's house, looking up at the gray-white residential building.

The July sun was scorching, making him squint.

He subconsciously loosened his collar, feeling that his shirt was already soaked with sweat.

"Captain Luo, what are we waiting for?"

Chen Xuanran stood behind him, impatiently fanning himself with a folder.

"The other groups have already started taking action."

Luo Fei did not answer immediately; his gaze was drawn to a luxuriously decorated hair salon across the street.

The glass door of the hair salon is adorned with the four large, gold-plated characters "Parisian Dream," and through the floor-to-ceiling windows, you can see several young girls in uniforms serving customers.

"Look at that hair salon."

Luo Fei suddenly spoke up, took out his phone, swiped a few times, and then handed it to Chen Xuanran.

“There is a photo in Zhang Weiwei’s WeChat Moments, and the background is this store.”

Chen Xuanran took the phone. In the photo, Zhang Weiwei was smiling brightly, with the "Paris Dream" sign behind her.

She was wearing a red dress and carrying an expensive-looking bag over her shoulder.

"so?"

Chen Xuanran returned the phone to Luo Fei.

"Even if she is a customer here, what does that prove?"

Luo Fei curled his lips into a confident smile that Chen Xuanran both loved and hated.

"This suggests she may come here frequently, and that the staff here may know something."

He straightened his collar.

"Let's go get a 'hair wash'."

"what?"

Chen Xuanran's eyes widened.

"Now?"

"Reimbursement of case-handling expenses."

Luo Fei had already started walking across the street.

"Just consider it an experience." Chen Xuanran bit her lower lip and quickly followed.

She didn't understand why Luo Fei was always so capricious, and she didn't understand why she was always being led by the nose by him.

Pushing open the glass door of the hair salon, a blast of cold air hits you, mixed with the scents of shampoo and aromatherapy.

A girl in a black uniform with exquisite makeup came forward.

"Hello, do you have an appointment?"

Luo Fei revealed a charming smile.

"No, just passing by. Two of you, shampoo and basic treatment."

"Okay, please follow me."

The girl led them to the hair washing area inside.

"I am Xiaomei, and I will be serving you today. Xiaoling will take care of this lady."

Chen Xuanran was seated next to Luo Fei.

As she lay down, she caught a glimpse of Luo Fei chatting animatedly with the shampoo girl named Xiao Mei.

"Is this your first time visiting our store, sir?"

Xiao Mei asked while adjusting the water temperature.

"Yes, a friend recommended it."

Luo Fei's voice was tinged with laughter.

"She said the service here is exceptionally good."

Chen Xuanran rolled his eyes.

Luo Fei's "friends" were always his excuse to get close to him.

"Who is your friend? Maybe I know them."

Xiao Mei started wetting Luo Fei's hair.

Luo Fei lowered his voice, feigning mystery.

"Her name is Zhang Weiwei, she should come here often."

The sound of water suddenly stopped.

Chen Xuanran turned his head to look, and Xiao Mei's expression visibly stiffened for a moment.

"Sister Weiwei."

Xiao Mei's voice sounded somewhat unnatural.

“She does come often.”

Luo Fei pressed his advantage.

"Why haven't I seen her lately? I was thinking of asking her to come along."

Xiao Mei paused for a moment.

"She hasn't come for a while."

There was hesitation in his tone.

Chen Xuanran noticed that Luo Fei quietly took out his wallet from his pocket, pulled out an ID card, waved it in front of Xiao Mei, and then quickly put it back.

Xiao Mei's eyes widened.

"Officer?" she exclaimed softly.

"shush"

Luo Fei made a shushing gesture.

"We're just chatting casually. How much do you know about Zhang Weiwei?"

Xiao Mei nervously looked around, and after making sure no one was paying attention, she leaned down and whispered something in Luo Fei's ear.

Chen Xuanran could only see Luo Fei's brows furrowing deeper and deeper.

"Xiaoling, could you get me a dry towel?"

Chen Xuanran suddenly raised his voice, deliberately interrupting their private conversation.

The shampoo girl named Xiaoling responded and left.

Taking advantage of this moment, Chen Xuanran lowered his voice and questioned Luo Fei.

"Captain Luo, what are you doing? You're alerting the enemy!"

Luo Fei smiled dismissively.

Sometimes, you have to stir up the grass to scare the snake.

He turned to Xiaomei.

"Can I add you on WeChat? It'll be easier to keep in touch."

Chen Xuanran watched as Luo Fei and Xiao Mei exchanged contact information, and then saw Luo Fei make a few moves on his phone, clearly transferring money.

Xiao Mei's phone vibrated, and when she glanced at it, her eyes immediately lit up.

"Officer, this..."

She was both surprised and apprehensive.

"A little something for your trouble."

Luo Fei's voice was seductive.

"Is there anything else you can tell me about Zhang Weiwei?"

Xiao Mei bit her lip and leaned close to Luo Fei's ear.

"Sister Weiwei is being kept by someone."

She paused.

"The general manager of Sihai Group is surnamed Lü, and he has a wife and children."

Luo Fei's body visibly stiffened.

Chen Xuanran knew the importance of this information. Sihai Group was Luo Sihai's company, and they had previously suspected Jiang Xia.

"Is there any evidence?"

Luo Fei pressed for an answer.

Xiao Mei nodded.

“Sister Weiwei once came to get her hair washed after drinking too much and let it slip. Later she gave me five thousand yuan and told me not to tell anyone.”

She hesitated.

"I still have a photo of her and that Mr. Lü on my phone."

Luo Fei's eyes lit up.

"send to me."

Chen Xuanran watched the two of them huddled together checking their phones, and a nameless anger welled up inside him.

Luo Fei always acts this way when solving cases; he'll stop at nothing to get clues, even going so far as to exploit other people's feelings.

And she could only stand aside and watch forever.

"Captain Luo."

Chen Xuanran couldn't help but speak up.

"Should we leave? The other groups are still waiting for news."

Luo Fei didn't even look up.

"Wait a little longer."

He turned to Xiaomei.

When was this photo taken?

"Last month, I think."

Xiao Mei recalled.

"Sister Weiwei was especially happy that day, saying that President Lü promised to buy her a house."

Chen Xuanran couldn't hold back any longer and suddenly sat up from the shampoo chair, splashing water everywhere.

Xiaoling happened to come back with a towel and was startled.

"Madam, you..."

"I'm ready."

Chen Xuanran said coldly, grabbing a towel and haphazardly wiping his hair.

Luo Fei then noticed her unusual behavior and looked at her with a puzzled expression.

"what happened?"

"nothing."

Chen Xuanran answered curtly.

"You continue talking, I'll go out and wait."

She walked quickly to the cashier to pay, and heard Luo Fei say to Xiao Mei behind her.

"Contact me anytime if you need anything."

That gentle tone sent a sharp pain through her stomach.

Stepping out of the hair salon, a wave of heat hit him, but Chen Xuanran felt it was much more comfortable than the air conditioning inside.

She tried to calm her turbulent emotions.

Why does she get angry every time Luo Fei does this? They're just colleagues; it's his business how he investigates.
"Hey, what are you doing?"

Luo Fei's voice came from behind.

"A major discovery has been made."

Chen Xuanran turned around, forcing himself to remain professional.

"What discovery?"

Luo Fei waved his phone.

"Zhang Weiwei was indeed kept by a sugar daddy, but not by Jiang Xia, but by Lü Mou Chuan of the Sihai Group."

He lowered his voice.

"This case might be more complicated than we thought. Sihai Group is Luo Sihai's company, and Luo Sihai..."

“I know who Luo Sihai is.”

Chen Xuanran interrupted him.

"So now we need to investigate this Lü Mou Chuan?"

Luo Fei nodded.

"I have already asked the technical department to check his records."

He looked at his watch.

"Go back to the bureau and organize the information from the other groups. I'll go take a look around the Sihai Group area."

"go by yourself?"

Chen Xuanran frowned.

"The two of them are too conspicuous."

Luo Fei had already turned to leave.

"Let's meet tonight."

Chen Xuanran stood there, watching Luo Fei's figure disappear into the crowd.

He's always like this, acting arbitrarily and never considering her feelings.

She clenched her fists and suddenly made a decision.

Back at the hair salon, Luo Fei stood in front of the mirror, water droplets dripping from the ends of his hair.

He tossed his hair, his gaze casually sweeping around him, only to find several waiting customers giving him strange looks, some even secretly chuckling. (End of Chapter)
