Su Ping glanced sideways at Qi Yuan, then withdrew his gaze and continued to ask: "Are there any other clues?"

"That's all for now, how many more people should I visit?"

"Just take care of it yourself. If you have anything to do, report it anytime. I'll hang up here first." Su Ping said, and then looked at Xiao Gao: "Can you find Chao Huaqing's bank account records?"

"I'm afraid it won't be easy." Xiao Gao is also an old detective and knows all the rules here, so he said calmly:

"The current suspicion of Chao Huaqing mainly comes from our subjective speculation without specific objective evidence or testimony from others. There is no reason to issue a joint investigation notice and evidence collection notice. This Chao Huaqing is not simple. He must have a wide network of contacts, and he is also a bank employee.

Big customers may not necessarily buy it and let us check it."

After a pause, he glanced at Su Ping's face and added: "And if, Captain Su, you want me to find a way to hack into the banking system...

Putting aside the fact that this is illegal evidence collection, I just don’t think about it. With the level of protection of the banking system, to be honest, I can’t do it. Once the attack is discovered, it can be traced back in an instant. Those network security guys

Experts are not vegetarians.”

Su Ping curled his lips.

What Xiao Gao said is wrong. The banking system and the public security system may not be very easy to use, but the protection level is very strong. There may be some small bugs in them. It is not surprising that some people can use these bugs to gain some illegal benefits, but I think

Attack their system head-on...

These days, even if someone really has the ability to do it, they would not dare to say it, especially someone with Xiao Gao's status.

What's more, Su Ping also knew Xiao Gao well and knew that he did not have this ability.

"Okay, you can go about your business." Su Ping shook his head, thought about it, and gave some instructions carefully before looking at Qi Yuan again.

Qi Yuan stared at the photo, intently, thoughtfully.

Su Ping's brows twitched slightly: "What are you looking at?"

Qi Yuan quickly came to his senses, feeling a little guilty.

"..." The corners of Su Ping's eyes twitched and he couldn't help but complain: "Aren't you? I've seen a lot of rotten girls. I've only heard of rotten men like you."

"I don't have it!" Qi Yuan hurriedly explained: "I was just thinking that based on the layout of the master bedroom of the victim's house, this angle does look like he was hiding in the closet and filming secretly. But the previous investigation did not find any holes in the closet.

How did this person take the photo?

Or is there any other mechanism in this closet? If this is the case, then what Brother Gao just said is that it is more likely that Yao Chugui and his wife could plan this secret filming incident."

Su Ping was thoughtful, and then called Lao Wei and asked him to check the wardrobe.

A few minutes later, I discovered that there was indeed something wrong with the porcelain wardrobe as Lao Wei said. There were several thumb-sized pieces of decorative glass in it, which were actually thin glass coated with a white single-transparent coating. The glass

The back has been hollowed out. If you don't look carefully, you won't find any problems.

After hearing this, Xiao Gao slapped his forehead: "I said why the image quality is so bad, there is so much noise, the brightness of the picture is low and it is also grayish and white, and I also complained about why it is so bad these days.

The mobile phone lens has the nerve to use 20 million pixels as a gimmick, but it turns out this is what it is all about.”

Su Ping glanced at him sideways: "Have you done what you just asked you to do?"

"Right away, right away!" Xiao Gao said quickly.

Su Ping said yes, stood up again, and walked out while saying: "Xiao Qi, come with me."

"Oh." Qi Yuan quickly followed Su Ping out of the office, then went downstairs and came to the parking lot.

Qi Yuan was a little surprised: "Captain Su, are you going to visit Chao Huaqing?"

"Yeah." Su Ping nodded.

"I'm afraid it might alert the enemy." Qi Yuan advised: "After all, we have no evidence now. It's better to wait a little longer. Now that we have found him, if he really has a problem, sooner or later we will be able to find out.

To put it bluntly, if a person like him really committed the crime of hiring a murderer to kill someone, he would definitely not be clean in other aspects. As long as you are willing, sooner or later you will be able to find evidence of his other crimes. As long as he is enough to issue a summons notice

With the level of the book, I launched various investigations on him without any resistance..."

"Yes, my mind is a little smarter and I know how to use roundabout tactics." Su Ping smiled, then shook his head and said: "There is no need to go to so much trouble. Don't forget, Ju Zhenghai and Qian Zenggang have already fallen into our hands."

"But they didn't do anything after all," Qi Yuan said, "Is it possible that Captain Su planned to deceive him?"

Su Ping shook his head: "No need, just be aboveboard."

Qi Yuan was even more surprised: "How do you say that?"

"We have their mobile phones in our hands." Su Ping said: "Although there are some problems with the real-name system of the cards used, it is not a problem.

Through the operator, based on these two cards, combined with the time of the crime, etc., we determined a suspicious call record.

Although the number in the call record had problems with the real-name system, it was actually registered with the ID card of an old man who died and had his account canceled three months ago...

But it doesn’t matter, that card may not have been destroyed by Chao Huaqing. You said, we should call this number directly in front of him..."

"Well," Qi Yuan scratched his head: "Captain Su, what if the phone carrying the card is turned off? As long as Chao Huaqing is smart enough, he should choose to contact Ju Zhenghai through a single line. If necessary, he can turn it on again to contact Ju Zhenghai and the others. There is no need.

Just don’t turn it on.”

"Of course I won't ignore this problem." Su Ping shook his head: "But it has been turned on after all, and we can still find the approximate location when it was turned on. The records of logging in, logging out of the base station, and data exchange with the base station will be

Keep it for a while.”

"What should I do if he doesn't admit it?" Qi Yuan asked again, and then explained: "Um, Captain Su, I'm not a gangster, but this possibility does exist, right?"

"What does it matter?" Su Ping smiled: "There are surveillance cameras all over the roads now. If he doesn't recognize it, we will adjust the surveillance. If every time, he happens to enter and leave the approximate location range of the number within a period of time...

Coincidence is not enough evidence to convict, but it is enough to establish suspicion."

After a pause, he continued: "I have already asked Xiao Gao to do this. I guess we will get the results when we get to Chao Huaqing's company."

"Understood." Qi Yuan nodded, indicating that he was taught.

"You're good." Su Ping said calmly: "You've been able to discover the problem as comprehensively as possible. But that's not enough. Next, you have to learn not only to discover the problem, but also to think of ways to deal with these unplanned problems.

Solution."
