"This Qin Jianbin, does he really meet all the conditions?"

Seeing the evidence gathered so far coming together, Liao Xingyu was extremely excited, and Zhou Fan also widened his eyes.

"Yes."

Luo Fei let out a long sigh, looking at the man in the photograph, along with the introduction of his identity, his eyes filled with a determined glow.

He not only had the same distinctive features as the perpetrator but was also engaged in work related to electronic locks, which gave him the means to commit the crime.

"The conditions are met, now what's missing is his true motive and other evidence for the crime!"

Luo Fei shook the materials in his hand.

"It seems I need to make a trip to Kangcheng Electronics Technology."

This psychopathic killer is extremely dangerous, and to ensure that no more people fall victim, it's crucial to quickly identify him and bring him under control.

The other three top suspects can be set aside for now; the main target is this highly suspicious Qin Jianbin.

With that, the group headed to the company where Qin Jianbin worked.

Upon arriving at the company, they found that he wasn't there and hadn't been for three or four days. He had been quite busy recently.

Whether inquiring at the front desk or with other department managers, they all expressed confusion and ignorance regarding Qin Jianbin's situation.

"Mr. Qin? It's strange, his mental state hasn't been good recently, always out of it."

"Yes, yes, we asked around and heard it might be an emotional issue, but that's unsure."

"Though Mr. Qin is capable and skilled in business, his frequent absences make it hard to explain to the higher-ups; the chairman has reminded him multiple times, yet Mr. Qin still does things his own way."

Everyone's accounts of Qin Jianbin were largely consistent.

Confronted with such a situation, Luo Fei felt a bit helpless, but since they were already there, they couldn't leave empty-handed.

So, he and Liao Xingyu went to his office to look for any clues.

If he was in charge of electronic locks, there must be related evidence here proving his involvement, which is important.

Though there's some evidence already, it's not sufficient.

Because some confidential documents weren't in his office, the employees didn't mind too much and took Luo Fei and the others there.

In the office, Luo Fei saw several electronic lock displays.

"These were all designed by Mr. Qin earlier. Since he was promoted from the technical department, his expertise is the best here."

"These are new products developed in the last two years, with excellent sales; we've recommended them to our friends."

The nearby staff introduced them.

As Luo Fei and his team walked and looked around, they were suddenly drawn to an electronic lock in the center.

"The photo."

Liao Xingyu took out the previously recorded content for comparison, and they instantly realized that these had all been arranged by Qin Jianbin.

"Could you help us check the user information? In the past six months or so, has there been any business with these two ladies at your company?"

Luo Fei gave Jiang Qing and Guo Wei's personal information to them, but upon seeing the information, the staff seemed a little troubled.

They were supposed to keep matters confidential, especially electronic business, and couldn't just leak user information.

Even though the police investigation was official, he hesitated about whether to report to his superiors.

Seeing the hesitation, Luo Fei straightforwardly explained the reason.

"They both died."

"These two women were unexpectedly murdered, and there were issues with the locks at the crime scenes. Don't worry; it's not a quality issue, but there are hidden aspects that need verifying their connection."

"Understand, understand."

The staff member was already a little flustered.

Facing a matter involving lives, they dared not delay, so they went to investigate immediately while Luo Fei and Liao Xingyu waited in an office on the first floor.

Logically, as a department leader, Qin Jianbin wouldn't leave randomly and be absent for so long.

His disappearance during this period becomes even more bizarre.

Moreover, he was the one leading the research and design of that lock!

Luo Fei pondered quietly; if there were any details he overlooked, it would be Qin Jianbin's familiarity with these locks.

If he could indeed enter freely, why would he need to break it?

It's all just a smokescreen!

Soon, the information came back; according to the staff, Jiang Qing and Guo Wei did indeed order locks from their company, precisely one month ago.

However, the billing list was under Qin Jianbin's name, indicating he used his own account.

In other words, the so-called lock replacement was something Mr. Qin had actively arranged for the two victims.

"It really is him!"

Liao Xingyu suddenly stood up, his eyes serious. Now there's no need to ask; this guy must have tampered with the locks.

"Get the technical department leader here; we have something to discuss with them."

Luo Fei continued examining the user records, and it seemed just as he initially suspected.

There was some entanglement between them!

All this started after they topped the leaderboard through tipping.
