Chapter 209 Information

Hearing Tang Rannuo's instructions, the golden retriever dog barked twice, sniffed the ground with its nose, and moved towards the entrance of the community.

Wanrong Community had just changed properties before, and the access control device at the door was still being repaired. Two players walked into the community openly, pretending to be a couple of ordinary residents, leading their dogs, and walked towards the building where the incident occurred.

The two mingled into the crowd, Tang Rannuo quietly let go of the leash, and let the golden retriever run out by himself.

While running, the dog tilted its mouth, shook its head, seemed to be dancing to some kind of weird music, rushed into the garbage dump behind the community, and began to plan.

Li Ang raised his eyebrows, and said softly, "Is this it?"

Tang Rannuo smiled and said, "It's about releasing skills, you'll know later."

Li Ang nodded, suddenly thought of something, and reminded: "Walking the dog without tying it is the same as walking the dog.

Won't you accompany it to stand next to the garbage dump for a while? "

"..."

The corners of Tang Rannuo's eyes twitched, and there was no expression on his pretty face wearing sunglasses.

She pretended not to hear Li Ang's words, and pretended to be an ordinary community resident, looking inside the cordon curiously, listening attentively, trying to get information from the gossip of the community.

The deceased Xia Junqiang lived in a rented house, and his landlord happened to be among the onlookers.

According to the landlord, Xia Junqiang signed the rental contract about half a year ago, and he seems to be very honest.

His job seems to be a freelancer, who usually relies on writing some programs to make a living, taciturn and unsociable.

According to the descriptions of the neighbors, Xia Junqiang always likes to stay at home and only goes out on Saturdays and weekends.

Usually, few relatives and friends would come to visit. Even if he went downstairs to go out, it was to pick up takeaway, or to go to the supermarket to buy some daily necessities.

A few days ago, someone saw him picking up the courier from the courier locker in the community, but he didn't expect to die so inexplicably...and the cause of death is unknown.

Residents in the community didn't know that Xia Junqiang was a suspected murderer, and they were still chatting nonsense.

Discuss that contemporary young people always stay up late, don't care about their health at all, and are in danger of sudden death at any time.

The landlord also kept feeling, complaining in a low voice,

I'm afraid it will be difficult to rent out this house after someone dies.

Even if a tenant is found, the rent will have to be reduced a lot.

This part of the chat is of no value, Li Ang shook his head,

It was found that the official criminal investigators seemed to be still upstairs investigating the scene, and had no intention of coming down at all.

According to the information he heard at Wang Congshan's house before,

I'm afraid Xia Junqiang's strange death has attracted investigators from the Special Affairs Bureau, who are now upstairs assisting Yin City's criminal investigators in their investigation.

Li Ang didn't think about contacting the Special Affairs Bureau directly, even through the vest, it would be too dangerous...

He sensed something, turned his head, saw Tang Rannuo gave him a look, immediately retreated from the crowd with understanding, and went around to the path at the edge of the community with her.

"How to say?"

Li Ang spread his hands and said, "Now there is no way to directly obtain information about Xia Junqiang's body. I suggest going to the stairwell of another building and using a pocket telescope to see clearly the room Xia Junqiang rented."

"Wait a while, Mao Mao hasn't come back yet."

Tang Rannuo shook his head, raised his phone, and looked at Li Ang calmly, "By the way, I have Xia Junqiang's personal information here, do you want to see it?"

"No, I have it too."

Li Ang smiled, took out the disposable smartphone for vests from his pocket, swipe the screen quickly, and browsed.

To find out the cause of the programmer Xia Junqiang's death, it is natural to know his social relationship first.

The best way to find out social relations is to buy residents' information.

In the era of network information, people have actually lost their right to personal privacy on an objective level.

Registering an app requires a mobile phone number, online shopping requires bank card information and detailed residential addresses, and entering Internet cafes, high-speed trains, and hotels requires face recognition and ID cards.

Name, gender, phone number, address, education, travel records, hotel records, SMS records, online shopping records, driver's license information, bank card information, current location....

All information is kept by major enterprises and network operators.

Logically speaking, this information is separated from each other and will not be leaked.

However, the huge gray industry information demand has given birth to the birth of the information dealer industry.

The debt collection industry needs the phone number, address, and address book information of the debtor, the fraud group needs a lot of citizen information, and the real estate agency needs the information of the buyer...

demand, benefit,

Benefits, spawning industries.

Enterprises in charge of private information sell citizen information in the system to information dealers, and information dealers build huge databases and sell them to door-to-door customers.

This database is so large, complex, cumbersome, and all-encompassing that it can even provide customized services for those guests who can afford it.

You only need to pay a fee of several hundred or thousands of yuan, and a mobile phone number, and all the information of the owner of the mobile phone number can be provided within a few hours.

Household registration, hotel records, criminal records, ID card track, work track, education track, mobile phone location, mobile phone bills, payment software bills, real estate certificates, marriage certificates, birth certificates...

In the age of network information, everyone is transparent.

When Li Ang was not in high school, he knew about this giant database system that was in a gray area, and used it to do some small experiments.

As early as when he was taking a taxi, he used the vest's disposable anti-tracking mobile phone to enter Xia Junqiang's name and the name of the community in the information dealer's database.

In the end, Xia Junqiang’s citizen information was found—the entire database system was set up in the dark web, and all processes from inquiry to purchase were automated, without the need for human hands, just transfer the money to the background of the system (use a A network currency similar to Bitcoin).

He already knew most of Xia Junqiang's information, but he didn't tell Tang Rannuo. There are two reasons.

One, it is to test whether the other party knows how to find personal information data and see if the other party is smart.

Second, it is to deter and threaten the other party - Li Ang already knows Tang Rannuo's address and name, even if she is currently using the vest identity, she can abandon it at any time,

But the longer the vest is used, the higher the possibility of revealing flaws,

The possibility of finding her true identity is higher.

Presumably, the reason why Tang Rannuo told him to find Xia Junqiang's citizen information is also the same - both parties have the ability to threaten to expose the other's true identity.

It's a pity that Li Ang, as the one who made the first move, changed his appearance in advance and concealed his whereabouts. He had a natural advantage in the matter of "concealing his identity".

Leaving aside the intrigue and intrigue between players,

Regardless of Tang Rannuo, whose face changed slightly, Li Ang swiped his phone, quickly browsed all the information on Xia Junqiang, and roughly pieced together his life trajectory.

Male, 29 years old, from Handong, parents divorced, grew up with the father of a freight driver, average family background, excellent grades since childhood, father died of illness in high school, majored in computer science at university in Yin City, won the ACM-ICPC competition with the team Awarded, without any hotel records (indicating that he has always been a single dog),

I got a serious illness during my senior year. After recovering from the illness, I entered a small and medium-sized Internet company as a developer as a programmer.

I worked for 6 years and was dismissed by my boss. I am currently working as a freelancer, relying on my programming skills and past savings to support myself.

There is no doubt that Xia Junqiang in the information is quite harmless to humans and animals, and has a lot of savings in his bank card.

Pick up a knife and commit a home invasion without any reason or motive.

Unless, those two deceased were acquainted with Xia Junqiang...

Li Ang frowned, realizing that things were not simple.
