After 100,000 simulated crimes, I became an ace detective.

now.

Although it has been roughly deduced that the butcher is now wearing a suit and carrying a briefcase, as an office worker commuting across the city.

Use public transportation to go to Suzhou Railway Station to escape.

But this is only to grasp the whereabouts of the Butcher and the escape route he finally chose. The current specific identity of the Butcher is still hidden in the fog.

And not only is the butcher's true identity unknown, there is even the possibility that he used a human skin mask to change his identity.

Because in these years, the butcher has never stopped committing murders. It seems that he enjoys killing and bloodletting. New victims appear every year.

The probability of identity exposure is actually increasing every year because of this.

So even though the Butcher believed in his anti-investigation capabilities, he was so arrogant that he didn't go to Qiangwei to customize a human skin mask.

With K's usual caution, he would definitely help the butcher prepare it, or force him to prepare enough human skin masks to avoid being traced by the police and causing the entire organization to be discovered.

Therefore.

Finding the butcher's current disguised identity and determining the train number and seat he is going to take are undoubtedly the most important things.

......

The car is speeding on the road.

Liu Yang, who had been a little confused before and didn't understand why he wanted to go to Gusu Railway Station, was completely convinced by Su Ming's reasoning and thinking.

Relying on his many years of criminal investigation experience and his familiarity with major roads, he stepped on the accelerator and took a shortcut, heading to the Suzhou Railway Station at full speed.

The car passed the early morning garbage trucks and the buses that had just started running.

Bai Yu, who was sitting in the back row, did not choose to wait for the results while heading to the Suzhou Railway Station at full speed. He used his mobile phone to check the map and traffic information of Suzhou City and analyzed it.

"that......"

"I checked and found that if you come from Shimao Jincheng Community and take public transportation to the Gusu Railway Station at the fastest speed without driving or taking a taxi, it will take at least an hour."

"First of all, since he wants to disguise himself as an office worker, the butcher must not be too extravagant. At least he must not take a taxi to the Gusu Railway Station."

"Shimao Jincheng is an old community and there is no subway passing nearby, so the butcher needs to take bus No. [-] to the most convenient subway station and take Line [-]."

"But the running time of the bus is six o'clock in the morning, so the departure time of the butcher and the fastest arrival time at the train station have been restricted."

"So if nothing else, although the butcher may have left the house very early, he got on the earliest bus to the nearest subway station at six o'clock."

"At the speed of the bus, it will take about ten minutes to reach Line [-], which is the most convenient to take and transfer."

"After taking the early subway at [-]:[-] in the morning, Butcher had to change to Line West in the middle of the morning to finally arrive at the Suzhou Railway Station."

"The subway ride takes thirty minutes, and the bus and subway take a total of fifteen minutes west. The current time is six fifteen minutes west."

“Since the subway is connected to the train station, it doesn’t take much time to get to the train station.”

"Based on this most appropriate transfer method, the train to Shanghai that Butcher ordered should be after seven in the morning. It would be difficult to go earlier."

"It is even very likely that it is the seven o'clock one, because according to previous statistics, due to the fixed operating hours of buses and subways, many office workers come to Gusu Railway Station, which generally takes ten to fifty minutes to the west."

"The train that goes to Magic City at [-] o'clock happens to be able to connect seamlessly. You don't need to waste too much time waiting, and the overall time is not too rushed."

"So Brother Quan... I think you can focus on screening the trains from Suzhou to Shanghai between seven and eight o'clock, especially the seven o'clock train."

It is clear.

With the same focus in mind, the butcher is likely to use cross-city commuting to escape from Suzhou to the Dao Demon City.

Bai Yu is also using his own methods to dig out the butcher's true identity as much as possible.

Regarding Bai Yu's inference, An Quan did not answer, but he nodded slightly to show that he was aware of it, and he focused his attention on connecting to the internal platform and screening suspicious persons.

......

five minutes later.

An Quan put the notebook on his knees and kept typing on the keyboard with both hands. At this moment, he suddenly stopped what he was doing and adjusted the glasses on the bridge of his nose.

While handing the notebook to Su Ming, he spoke quite seriously.

"found it!"

"Based on Xiaobai's inference, after further narrowing down the possible train numbers, I have screened a total of three suspicious persons with matching characteristics."

"Our country's official 12306 train ticket online sales channel is from [-]pm to [-]am, which is a system maintenance time."

"So if the butcher books a ticket, the approximate time period is from five o'clock to now, especially the few minutes after the system is maintained."

"And I personally feel that... the butcher will definitely book the ticket as soon as possible. After confirming the train ticket to the Magic City, he will then plan the subsequent escape operation."

"The facts are exactly what I thought."

"The three suspicious people I screened who fit the criteria basically booked their tickets to the Magic City within ten minutes of the system being maintained."

"In fact, from five o'clock to now, the number of cross-city commuters who have booked tickets from Suzhou to Shanghai, or some passengers with urgent matters, is not small."

"During the preliminary screening, a total of nearly [-] people booked tickets from Suzhou to Shanghai in the early morning."

"After setting the departure time within the range of seven to eight o'clock in the morning, eighty people were immediately reduced to only ten people in the west."

"But then all important features such as gender, age, daily commute, daily return, seat class and recent ticket bookings were filtered."

"Of the original eighty people, only these three are left."

"If nothing unexpected happens, one of the three people who bought tickets to Shanghai in the early morning may be a butcher with a hidden identity, but it is not yet completely certain."

Look at the filter entries and methods in the notebook screen.

Su Ming nodded with satisfaction. From the perspective of migrant workers commuting across cities, Bai Yu and An Quan's judgments were indeed accurate.

Relying on the operating hours of public transportation, the approximate train time can be determined, reducing the original number of suspicious persons by half.

Starting from the characteristics and frugality of office workers, we further narrowed the scope, and now there are only three possible candidates left.

Looking at the identity and ticket information of the three people displayed on the laptop screen.

Su Ming immediately discovered that the trains booked by these three people were completely different. In addition to the one going to Magic City at [-] o'clock, there were also two trains at [-]:[-] and [-] o'clock.

At the same time, there is a very important point...

None of these three people had any commuting information for the past few days, nor had they booked tickets for today's return trip. At the same time, they had not even taken a train in the past year.

Even though this drug trafficking organization is very powerful, it can prepare several matching new identities and human skin masks for each member for subsequent escapes.

But K has absolutely no way, let alone enough energy, to maintain this identity information every once in a while.

So it will lead to...

According to the police's internal real-name system records, this kind of unmaintained backup identity has no real-name information about hotels, Internet cafes, transportation, tourist attractions, etc., and the abbreviation is no different from a whiteboard.

In the past, when there was no discovery or strict investigation, there was no pressure to use it.

But now...it has become the best guiding light.

this moment.

Su Ming squinted his eyes slightly, looked at the three identity information on the screen, and pointed out something.

"With Butcher's outstanding anti-reconnaissance capabilities, even the tourist group can think of booking one to confuse our sight."

"So is it possible that these three people... are actually butchers?"

Are all three butchers?

......

This time.

The people in the car no longer had many doubts about Su Ming's conclusion.

Because it's just like what Su Ming said.

With Butcher's excellent anti-reconnaissance capabilities, even provincial tourist groups can book Western tours. This is for the sake of safety and concealing his whereabouts as much as possible.

It is naturally normal to use three different identities to book trains to Shanghai at three different times.

Liu Yang, who was driving at this time, turned his head and glanced at Su Ming, and said in confusion.

"Xiao Ming."

"Even if the butcher uses three different identities to book tickets, it should be useless, right?"

"Because when entering the train station, you need to be connected to the Internet for face recognition. The railway's internal backend can immediately determine..."

"Which identity did the butcher use, which human skin mask did he wear when he entered the Suzhou Railway Station, and where was the train number and seat he ordered?"

"If it were locked in this way, wouldn't it be possible to easily determine the butcher's current identity for the first time?"

Regarding Liu Yang’s words.

Su Ming shook his head slightly, not as relaxed as he thought, and spoke expressionlessly.

"Liu Bureau, it's not that simple."

"Although when entering the train station, face verification is indeed required, so that we can initially determine the identity of the butcher to enter the train station."

"But the problem is... when the vehicle arrives at the station to check in, face verification is not required, which leads to..."

"No matter what identity the butcher uses to enter the train station, he can actually ride on any of the three cars at will. This is the loophole in our ride system."

"Even more extreme, if he chooses the [-]:[-] or [-]:[-] train, he still has time to change the human skin mask on his face to further hide his identity."

Hear this.

Liu Yang was stunned for a moment, slapped the side of the steering wheel with his palm, and frowned slightly in surprise.

"Xiao Ming, is this too exaggerated?"

"Then the butcher can decide which car to leave at any time. Is he really so cautious at all times? Can he maintain such excellent anti-investigation capabilities at all times?"

"It stands to reason that from his perspective, we should not know about his cross-city commuting escape plan yet, so the target should be on the provincial tourist groups."

"But it shouldn't matter much, right?"

"As long as we can arrest and control the butcher first when entering the station..."

Speaking of it.

Liu Yang immediately looked at the time displayed on the big screen in the car, and then patted the steering wheel harder, feeling a little excited.

"Damn it! It's already too late."

"We just set off relatively late. I estimate that it will be around [-]:[-] when we arrive at Gusu Railway Station. I'm afraid the butchers have already entered the station."

Su Ming handed the notebook in his hand back to An Quan, and squinted his eyes slightly to indicate what Liu Yang had just said.

"Bureau Liu."

"I don't think a butcher can still run away with dozens of lives in his hands and he hasn't received any peanuts yet."

“How much relief comes when tension escapes like this.”

"Then, since the butcher cannot be arrested before face verification, I think the best way at the moment is..."

"Ask the staff at the train station to assist and monitor the incoming background information at all times. Once the butcher is found to have entered the train station with one of these three identities, we will be notified immediately."

"And call all the surveillance cameras in the train station to control the butcher's movements at all times to prevent him from disappearing from sight."

"However, never let the police conduct arrests to avoid unnecessary accidents."

"Because the Butcher's danger, force, and ferocity are definitely not comparable to Qiangwei's, and besides, we have to catch him alive this time!"

......

at the same time.

At the transfer station between Suzhou Metro Line [-] and West Line.

A large group of cross-city commuters poured out of the carriages of Line [-] and walked quickly towards the West Line not far away.

These cross-city commuters generally wear suits or business attire and seem to have jobs that others consider decent.

only.

Due to the high housing prices in the city, I have no choice but to commute across cities, wasting several hours every day on the distant commute to work.

Among the crowd at this time.

An ordinary office worker wearing a black suit and carrying a briefcase, about 185cm tall, was following the flow of people preparing to transfer to the West Subway.

But compared to the eyes of other office workers, whose edges have been smoothed away by life and lifeless, leaving only fatigue and looking forward to the weekend.

The eyes of this ordinary office worker were indescribably gloomy and cold.

From time to time, he would use small movements to cover up and constantly observe the surrounding environment, especially those inside the subway who were wearing work clothes.

When I finally got on the West Line and the subway started.

This ordinary office worker took out an ordinary mobile phone and sent a message to a rather special number.

"Everything is normal, we are escaping from the big net as planned..."
