Chapter 579: Chapter 579: Success Without Effort

In recent years, although the 116 case hasn’t been solved, someone has been closely watching it.

Qin Hui himself has contacted Xi Mengyao’s stepfather a few times, so he naturally knows where they live.

North Mountain Park Community.

Knock, knock, knock.

Soon after knocking, the door opened, and Lu Chuan saw a shiny bald head.

"Captain Qin?"

"What brings you here?"

The bald man seemed slightly surprised to see Qin Hui at the door.

"Please, come in!"

After a brief pause, he warmly invited the three of them in.

The bald man had a simple and honest smile, his voice was gentle. Despite having no hair, not even many eyebrows, he didn’t give off a fierce impression; instead, he seemed harmless.

Lu Chuan followed beside Qin Hui, while observing the man’s physique and some details.

He opened the door with his left hand!

When the bald man opened the door, he used his left hand!

The door of the bald man’s house opens inward, opening from left to right.

Most doors open from left to right when observed from the inside, as they are designed to be opened with the right hand by most people.

Because most people are right-handed.

However, when the bald man opened the door, he used his left hand to pull the door handle.

This indicates that the bald man is likely left-handed.

"Mr. Qin, sorry for the unannounced visit, but there are some things about the case back then that we need to discuss with you."

Qin Dejun, Xi Mengyao’s adoptive father, and the bald man’s name, Lu Chuan had already reviewed his information on the way.

He used to sell pork at the farmer’s market, later he saved his first bucket of gold and started doing other things.

But what exactly, no one seemed to know.

"Oh, Captain Qin, is there any new lead recently?"

Qin Dejun was very polite, and after Qin Hui and the others came in, he took the initiative to make tea for them.

Lu Chuan remained silent but continuously observed Qin Dejun’s actions.

He poured water, handled tea leaves, and passed the teacup with his left hand.

"Mr. Qin, are you left-handed?"

Qin Dejun looked at Lu Chuan, assuming he was a follower of Qin Hui due to his youth, and laughed, not caring much.

"Young officer, you are observant. Captain Qin, is this your apprentice?"

Qin Hui shook his head, thinking he wished he had such an apprentice, but he didn’t explain because there was no need.

Wang Ruiqing did not enter and left after a while.

Qin Hui only symbolically asked a few questions before taking his leave.

"Captain Qin, if there’s any progress on the case from back then, please let me know."

"Mengyao... the suffering Mengyao endured back then... can’t let them get away with it!"

...

Outside the community.

"Did you get it?"

Wang Ruiqing nodded: "While you were chatting inside, I got Qin Dejun’s footprints at the door."

"Let’s go verify it."

"Probably unnecessary, this Qin Dejun is likely the second suspect in the Tianzhou City family annihilation case!"

Lu Chuan’s face was stern.

Based on the footprint analysis at the scene, the second suspect in the Tianzhou City family murder case is a male, about 170 cm tall, weighing 60 kg, and left-handed.

Moreover, this suspect was the murderer who dismembered the child in the kitchen.

Qin Dejun’s height and weight matched the footprint analysis characteristics of the second suspect as Lu Chuan determined.

Besides, the fact that he is left-handed and had been a butcher further convinced Lu Chuan that he was the second suspect.

After explaining the relevant situation.

Qin Hui thought for a moment.

"Ruiqing, go back to the team to do the footprint identification comparison. Lu Chuan and I will stay here just in case, and arrest Qin Dejun immediately once it’s confirmed."

Although Wang Ruiqing didn’t have extraordinary skills in footprint identification and analysis, comparing two footprints is probably not a problem.

So there was no need for Lu Chuan to go back.

Qin Hui and Lu Chuan waited in a small shop next to the community after getting out of the car.

Wang Ruiqing quickly returned to the Criminal Investigation Team.

As long as the comparison is successful...

Then both the Tianzhou City family annihilation case and the 116 case from three years ago will be resolved!

Just thinking about it is exciting!

"How confident are you?"

"At least 80%!"

Lu Chuan also saw Qin Dejun’s shoes at the door.

Though not compared, the footprints at the Tianzhou City family murder case site are etched in Lu Chuan’s mind.

There’s an 80 to 90 percent chance that this Qin Dehui is one of the culprits.

However, there’s a question that has been puzzling Lu Chuan.

If Qin Dejun is indeed the suspect, why did someone so cautious in the Qinzhou City Vocational and Technical College crime leave so many footprints in the Tianzhou City family murder case back then?

The hair is explainable now.

Qin Dejun’s big bald head wasn’t shaven but natural, even his eyebrows were sparse.

A person born without body hair also has none below, hence if he committed a crime, it explains why there were no friction injuries in the victim’s private parts.

But what about the footprints?

In the 116 case scene, he knew how to erase footprints, using a mop from the dormitory to erase any trace, yet three years later, in the family murder case, he didn’t do so. Why?

Was he careless?

No!

Impossible!

Absolutely impossible!

Wang Song and Song Mingguang, while tracking surveillance in Tianzhou City, found the suspect extremely cautious and well-protected. Even during a verbal conflict with the victim’s family of three in a hot pot restaurant, they weren’t exposed on surveillance cameras.

This indicates strong anti-investigation awareness.

So, it couldn’t have been left carelessly. 𝓯𝓻𝓮𝙚𝙬𝓮𝙗𝒏𝙤𝒗𝙚𝙡.𝒄𝒐𝓶

If it wasn’t carelessness, why were the footprints erased back then but not now?

How to explain it?

Xi Mengyao’s image reappeared in Lu Chuan’s mind.

Their innocent and pure smile seemed infectious with just a glance.

They chatted while waiting for Wang Ruiqing’s comparison results.

Forty minutes later.

Qin Hui’s phone rang.

"Captain Qin! It’s a match!"

Qin Hui’s eyes lit up!

Damn it!

Lu Chuan was right!

This bald guy, it really is him!

"Arrest him!"

The two left the supermarket and headed straight to Qin Dejun’s house.

"Captain Qin? Why are you back?"

Opening the door, Qin Dejun, seeing Qin Hui and the young officer who just mentioned being left-handed return, was full of surprise.

"Qin Dejun! You are under arrest!"

Arrest?

"Captain Qin... are you making a mistake?"

"I..."

"What crime did I commit?"

What crime?

"Qin Dejun, half a month ago, Tianzhou City, did you forget?"

Tianzhou City?

Hearing Lu Chuan’s words, Qin Dejun’s face changed.

He suddenly lowered his body, trying to charge through between the two of them.

Lu Chuan had been keen on observing his every move.

Trying to run?
