Xun Mu snapped his fingers and said, "Correct." ”

After a pause, he continued: "During the period of about 10 to 15 years, parkour and other similar extreme sports were very popular in China, and my Yuqiao was also very popular, but after 15 years, the popularity quickly decreased.

At the time of the hottest, there were several parkour parks in the city, and similar enthusiasts could be seen shooting on the streets from time to time, but now they are basically gone, and most of the parkour teams are probably disbanded.

So...... Our investigation is actually not very large, and if it goes well, we may be able to identify a suspect today. ”

Giving the detectives a little thought for the autopsy, he continued: "Finally, the technical team. There is no breakthrough in this piece for the time being, but there is a suspicion - the desktop computer in the study looks intact from the outside, but it can ...... The hard drive was taken away. ”

"Hard drive?" Su Ping looked sideways: "The suspect took the hard drive of the victim's home computer?" ”

"That's right." Xun Mu said: "I didn't move anything else, and the hard drive was taken away." Come to think of it, if it weren't for the fact that the machine was too big and heavy, they might have directly resisted the entire chassis - the victim's computer was quite high-end, with water cooling, it would have to weigh twenty or thirty kilograms. ”

"The hard disk is not valuable, and it takes a little effort to disassemble the hard disk and get it, what do they do when they take the hard disk?" Su Ping frowned: "Obviously, it can't be a temporary idea...... Then, one of the murderer's goals, I'm afraid it's this hard drive.

Is it related to the motive for the crime? The murderer broke into the house for this hard drive...... Was the murder an incidental purpose, or was it one of the planned purposes earlier? Got an important secret in your hard drive? ”

"He wouldn't have taken pictures of other people's fruits, would he?" Qi Yuan couldn't help but say: "Many photographers seem to love to shoot private rooms, and some of them may indeed be for art, but I think there are also many of them, which have nothing to do with art, just to satisfy some kind of selfish desire." ”

Su Ping and Xun Mu looked at it at the same time.

Qi Yuan immediately continued: "And there are even more dirty ones, after the shooting, after processing, the original is not deleted, but kept for sale, and even directly threatens customers or models, in order to extort money, or carry out some special transactions."

Of course, if Yao Chugui is a pure gay, then the possibility of making a special transaction is relatively small, but the possibility of extortion of money still exists.

If he had done such a thing that violated professional ethics, the customer would have been overwhelmed and would have killed him and retrieved the photo in order to avoid the threat. Or if this matter is known to the boyfriend, husband, family members and others of the person being filmed, they may also make the decision to kill Yao Chugui and retrieve the hard drive. ”

"Indeed." Su Ping nodded lightly, followed by the center of his eyebrows twisted into a pimple again, and said, "It's a pity...... The hard drive has been taken, let's ......"

"Maybe there's another way." Qi Yuan said again: "Personal network disk." He might upload his photos to the online drive. Or, you may have a portable hard drive, a private LAN drive, and so on.

Engaged in photography, the capacity of the photos taken is not small, a may have more than ten or twenty trillion, the number is more, the computer hard disk space is not enough at all, so it is stored in the network disk, mobile hard disk, local area network disk, etc., in fact, it is quite common. Perhaps we should investigate this further, including the victim's home. ”

After a pause, Qi Yuan added: "For example, the current smart router, the mid-to-high-end intelligent router launched by several major Internet brands, can be connected to a mobile hard disk or a built-in hard disk to build a personal LAN, but last night's on-site investigation, it seems that the router was missed." ”

As soon as these words came out, several people couldn't help but be slightly stunned.

Su Ping said: "Okay, Xiao Qi, you know a lot about this business?" ”

"I had a roommate in college who was from the Photography Association, and now he does this, and I talk to him occasionally and know a little bit about it." Qi Yuan scratched his head, smiled embarrassedly, and then said:

"This kind of router for building hard disks, in fact, the penetration rate is not particularly high, only some geeks and people who really need it will use it, so it is easy to be ignored, including us, I think the murderer may not have noticed it - of course, the premise is that Yao Chugui engaged in this kind of router."

Lao Wei immediately took out his mobile phone, looked through it, and then handed the mobile phone to Qi Yuan and asked, "This photo seems to have been taken on the router, but it's a big guy...... Xiao Qi, do you see if this router has a hard disk? ”

"Well, actually, I don't understand it either......" Qi Yuan said, and at the same time, his eyes couldn't help but look over.

Immediately after, he was slightly stunned and slapped his forehead: "Look, I just knew about this, and my classmate also used it, and he also recommended it to me!" Do you see this box on top of this route? That box is a mobile hard disk, connected to the router through USB, and you can use it when you connect it, fool-like operation! ”

Su Ping immediately said: "Old Wei, you immediately take someone to the scene again and bring the hard drive back!" Also, I searched carefully on the spot, and all electronic devices, even if it was just an MP3 that had been eliminated for many years, had to be brought back to me, and I couldn't let go of the slightest, understand? ”

"Understood." Lao Wei immediately got up, and at the same time sighed: "Live to learn all the time, especially if we are engaged in criminal investigation, we may fall behind if we are not careful." ”

"It's good to have this awareness, you can take someone there first." Su Ping said, and then took out his mobile phone again, and said while sending a message: "I now ask the technical team to find a way to analyze and analyze to see if he uses software such as network disks, and whether he can get the clues we need." ”

Xun Mu snorted, and then said worriedly: "There is a question - what if that hard disk is set up with hardware encryption?" With the ability of our detachment's technical team, for hard disk hardware encryption, there is no good technical means to crack it, I'm afraid it will ......"

"Not really." Su Ping rubbed his eyebrows: "In these days, there may be a small number of sensitive people and groups who need to encrypt hard disks on personal computers, but mobile hard disks ...... It's not going to be such a hassle......"

Before he finished speaking, he glanced at his phone and said with a smile: "Don't worry, even if there is hardware encryption, it can be skipped from the software level - the hard disk is plugged into the router, which means that the hard disk trusts this device, as long as the route does not restart, there is no need to enter the password repeatedly." We just need to connect to their wifi......"

Xun Mu frowned: "But we don't know their wifi password." ”

"......" Su Ping glanced at him: "Computer idiot? ”

Xun Mu: ???

Su Ping snorted and said, "Don't you know that the device can be directly connected to the wifi through the button on the router?" What password do you want? ”
