Before Lu Fang could wait ten minutes, Wang Tao had already driven the car in front of him.

As soon as he got into the car, Wang Tao couldn't wait to ask: "What did you find out? Is it worth it?"

"I locked in a suspicious person. If I could find some evidence to confirm his suspicion, I could use him as a breakthrough."

"What is he?"

"Elevator maintenance personnel are specifically responsible for elevator maintenance work in the entire building of Yongning Building."

Wang Tao was stunned and said, "Specialized maintenance? The elevator maintenance of Yongning Building is not outsourced?"

"It can be considered outsourcing. He is an on-site maintenance and his work is relatively fixed."

Wang Tao nodded: "Well... this identity meets the conditions for committing the crime."

Chatting the case all the way, more than half an hour later, the police car drove into the yard of the Tianyang District Police Station.

The cafeteria was crowded and it was already dinner time.

"Let's have dinner first! Work overtime tonight." Wang Tao said and looked at Lu Fang and said, "Xiao Lu, do you have a girlfriend?"

"No."

"I don't have a girlfriend!" Wang Tao was slightly happy, "That happens to work overtime."

Lu Fang nodded honestly.

...

There is nothing to say about the meal process, just like the food in the cafeteria is not worth commenting.

After the meal, the three of them returned to Xingda’s office.

The case about Chai Yuan is the largest case handled by the Criminal University of Tianyang District in recent days.

Although the part about Chai Yuan controlling the killing of wild leopards is relatively simple, once Wang Tao makes a breakthrough in this line and locks in the black market organization, he will be busy.

Therefore, in order to fix the link of evidence related to Chai Yuan’s murder as soon as possible, most of the elite police officers in Xingda were devoted to this case.

Therefore, although the get off work time has passed, the several office floors of the Criminal Investigation Building are still brightly lit.

If you want to talk about this case, you don’t have to work overtime, but if you don’t finish the case as soon as possible, what if another big case is suddenly released?

Did you say to the victim: Sorry, we have no police force now, wait first?

So, if you have a case, you have to handle it as soon as possible.

Lu Fang and Zhang Linze were in the same office, and sat in front of the computer and started working their own work.

In the past, Lu Fang had been staying in the police station and was forced to indulge in resolving conflicts and various inspections every day, and had few opportunities to use various data systems.

Now that he uses it, he doesn’t admit that this world is indeed much better than his previous life in terms of data resource integration.

Here, the police have assumed more responsibilities, and the above have also given more policy support.

Especially criminal investigation, the data you have mastered is comprehensive.

Basically, the data required for investigation by the police during the case handling process can be found in the big data system.

Too happy.

Now Lu Fang needs to investigate the relevant situation of Tan Xing.

It is not easy to confirm whether he is involved in the black market, but he can find it with one evidence and one evidence.

A condition that meets it can be said to be a coincidence.

But three or five, or even seven or eight?

That must be not explained by a coincidence.

Lu Fang now wants to find a way to increase the weight on the balance.

Information related to Tan Xing appeared on the display screen, and Lu Fang's eyes quickly passed by.

Ignore information directly...

"Tan Xing, an employee of Shengteng Special Equipment Maintenance Company, joined the company in May 3031 and was dispatched to Yongning Building in the same year to be responsible for elevator maintenance."

"Married, childless, currently living in Antai Community, Colin Avenue, ZS District."

The basic situation is almost all that, Lu Fang silently remembered it in his heart after reading it.

The remaining track information and communication information are a lot.

Who makes this type of structured information usually store for a long time? In addition, there are too many ways to obtain trajectories now, and everyone can generate a large amount of data every day.

If it is too little, it will be abnormal.

Fortunately, there are analysis and judgment models, otherwise, based on the naked eye and the human brain, it will drive people crazy.

After a sudden operation, Lu Fang was shocked to find that Tan Xing's trajectory was actually very simple.

After three years of joining the company, this guy has no record of leaving the market at once.

It is not an exaggeration to say that it is two points and one line.

Antai Community is only more than 300 meters away from Yongning Building, just by walking.

He wanders back and forth between offices every day.

When I occasionally go far, I basically go to shopping malls or supermarkets, and the number of times is pitifully small.

"Werewolf! The key is... Such a guy who is so homeless can get married?" Lu Fang seemed to feel hurt.

He stared at the lines representing the trajectory on the visual analysis interface, and he really couldn't find any abnormalities.

In desperation, Lu Fang began to read the call record again.

Then... Lu Fang found that this guy had no more than twenty phone contacts, and even the live chat tool he used did not more than fifty contacts, and most of them were lying in the address book after adding friends.

This person's interpersonal relationship is as simple as a piece of white paper.

Lu Fang frowned.

This is not normal.

Although it is not ruled out that there are indeed such people in society, and even more introverted people than this, Tan Xing should not be such a person.

He noticed some details.

For example, most of the calls he had with his wife were called out by him as the calling user.

Not only is it a contact with his wife, but it is also normal for others to contact with others.

This does not conform to the character of a person with an introverted personality.

Pretending?

Why pretend? Do you want to hide something? Or do you avoid something?

If Tan Xingzhen has something to do with the black market, this will be explained.

The simpler the interpersonal relationship, the lower the attention it receives and the less likely it is to be exposed.

Moreover, an introverted person can eliminate many unnecessary troubles, such as... a wine party.

If the inference is correct, then how did Tan Xing contact him online?

Lu Fang does not think they will use offline contact.

In this era when the number of monitoring probes is more than that of sparrow nests, it is best to do something about stealing and avoid offline connectors.

on-line?

There are still no traces of online communication?

Whether it is an instant chat tool, email, or Weibo, as long as you use it, there will definitely be traces, even if it is a software that burns after reading.

Lu Fang didn't give up.

Continue to find information about Tan Xing, focusing on some of his online identity information.

Suddenly, he saw an inconspicuous message that was very consistent with the identity of an otaku.

Online game, a mobile game of RPG.

This game was released three years ago, and Tan Xing downloaded the game at that time and looked flawless.

It was just a coincidence that this time was just a few days before he joined the company.

With some doubts, Lu Fang clicked on the detailed information about Tan Xing in this game.

This information is not particularly comprehensive, only login time, character level, etc.

However, it was this information that made Lu Fang completely calm down.

This guy has very little time to log in to the game, he only logs in once a week, and it only takes more than ten minutes to log in once.

The strangest thing is that every time he logs in, he is on Saturday at 8 pm.

Is this a game? Or a check-in?

With this frequency, why do you continue to play this game?

Is it love? Is it responsibility?

Nonsense!

He had a bold idea.

This online game is a den for those people in the black market to meet.

Although the game will archive some information, it is absolutely impossible to save the movement trajectory of each player in the game for a long time, nor can it save the chat records of all players for a long time.

Various factors make in-game chat the safest place.
