The time lasted until eight o'clock in the evening.
For such a long time, Li Mu didn't sleep a wink or eat anything. He drank Red Bull almost the whole time and his eyes were red.
The other people are basically the same as him, except that when they are extremely sleepy, they will lie down on the conference table and squint for a while, unlike Li Mu, who is not sleepy at all because of his inner anxiety.
At the same time, Taobao's 929 promotion has entered a new peak period. Order volume began to surge during this prime time, sales have exceeded 6.5 billion, and it has entered a growth peak.
Background monitoring shows that the system is giving out more and more prize-winning order coupons, and a large number of users who have purchased are still placing new orders. The craziest user has placed orders in the past 20 hours from 0:00 to now. Over two hundred orders! There are nearly one hundred and fifty unique addresses alone! It can be seen that Li Mu’s strategy of promoting order placement has taken effect. A large number of users have begun to help other non-registered users place orders and complete transactions, which has contributed to the overall sales of Taobao’s 929 sale.
Now all Taobao employees outside, the entire industry, and even people across the country are paying attention to the amazing achievements of Taobao's 929 sale, which has become a nationwide online shopping carnival. However, only Li Mu, the founder, has made great contributions to Taobao's achievements. There is no time to care about achievements.
It's eight o'clock! It's already eight o'clock in the evening! The first scene is still not confirmed!
As it gets completely dark, site inspection becomes even more difficult!
The impatience in Li Mu's heart was indescribable. He wanted to throw his laptop to the ground and stomp on it several times to vent his inner anxiety at this moment.
At 8:20, good news finally came: Wei Lan’s car was found!
However, twenty minutes later, another piece of bad news came.
The car was found, but no real valuable clues were found. The car was hit from the front and back. It seemed that at the time of the crime, she was attacked from the front and back by the other party, and then she was kidnapped. The kidnapper drove her car to a public parking lot. During the walk, almost all the traces that could be dealt with were removed. The on-site criminal investigation experts only collected the footprints of a male. Preliminary speculation showed that the man was about 180 centimeters tall, weighed about 65 kilograms, and was on the thin side.
The forged footprints had a very good confusing effect. The police finally found a clue related to the person, but they were still wrong.
Later, the clues were broken again, because the criminal investigation experts were chasing the footprints left by this man, and they could not pursue him for dozens of meters.
Feedback from the scene said: "The opponent climbed over the wall, and it is difficult to preserve the footprints on the cement floor. Moreover, 20 hours have passed, and pedestrians, bicycles, and motorcycles have been constantly crushing them. The possibility of extracting the footprints has been completely lost."
Gu Jianghe was also going crazy.
Chasing the suspect's car, but there was no trace; chasing Weilan's car, finally catching it, but it was a dead end; chasing the suspect driving Weilan's BMW, chasing the suspect for dozens of meters before losing the clue, this is simply It’s a rhythm that’s going to force people to death!
The criminal techniques of these guys are really superb, and they were able to deal with the scene and the evidence so that there is no clue. Although there is no truly seamless crime in the world, if you search carefully, you will definitely find valuable clues, but this is not a murder case, there are It will take several years or even more than ten years to slowly track down the murderer! This is a fucking kidnapping case! The kidnapping case also means that time waits for no one!
If no clues can be found within the next 28 hours and Wei Lan's location cannot be located, then the public security organs will basically have to wait for Wei Lan's body to appear and then use her body to track the criminal if they want to solve the case...
There was a brief silence at the scene, and despair brewed in everyone's heart, and then appeared uncontrollably on everyone's face.
Li Mu's hair was about to turn into a bird's nest. He really felt helpless at this moment. He knew it was Song Zhilei, but there was no clue to find him. This was so painful!
Just when Li Mu was about to run away, Li Mu suddenly caught a clue in his mind!
He stood up all of a sudden, and the chair under him was pushed far away. The huge movement startled everyone, and they all focused their attention on him.
Li Mu blurted out: "No matter what, Song Zhilei must have a mobile phone on him! He needs a mobile phone to communicate with his men, and he also needs a mobile phone to communicate with his wife and children! He has disappeared from the Shanghai stock market for six days. In these six days, he It is very likely that he has been planning a crime in Yanjing. He wants to kidnap and kill people. He cannot take his wife and children with him. He must frequently contact his wife and children for so many days! So he will definitely not turn off this mobile phone! At least not Shut down the phone for a long time! Find this phone, find the phone and you will find Song Zhilei!"
The criminal investigation expert nodded: "Mr. Li, you are right. According to common sense, he must have a mobile phone on him. However, we checked all the mobile phone numbers in his name and found that they were all switched off six days ago. This is also true. This means that the mobile phone number he changed now has no substantial connection with him personally. It may even be just a mobile phone card purchased at a street phone booth in any place. In the huge crowd, we can't find any relevant information at all. Clues…”
Li Mu shouted with great emotion: "Don't tell me that you can't find him at all! If you can't find him, check his wife and children! Check his wife and children! I want to know where his wife and children are now. ! Especially look at the entry and exit records to see if they are still in the country! Check immediately! Check immediately!"
Gu Jianghe immediately said to the criminal investigation experts and public security technicians around him: "Check the civil aviation records immediately to see if there are any travel records of Song Zhilei's wife and children!"
At present, there is no real-name system for trains and buses. The only real-name and recordable mode of travel is civil aviation.
The technician immediately used his computer to conduct a query. After a moment, he exclaimed: "Just six days ago, his wife and children took an Air China flight out of the country and flew to Australia!"
"Going abroad?!" Li Mu's eyes lit up and he asked hurriedly: "Can you find out whether their family has Australian green cards? Do they have any real estate in Australia? If they have real estate, do they have registered mobile phones and landline phones?"
Gu Jianghe immediately said to the technician: "Contact the security department and ask them to help cooperate with the investigation. It is an urgent matter. The sooner the better!"
Ten minutes later, the security department replied: "Song Zhilei's family has Australian green cards. They have a villa in the suburbs of Sydney, Australia. There is no mobile phone number registered there. There is a landline phone registered under the property, and the number has been found."
Except for Gu Jianghe, everyone else was completely shocked by the power of the security department. It was amazing that they were able to find out such detailed overseas information in such a short period of time.
After getting a fixed phone number in Sydney, Li Mu immediately became excited and asked the technical staff of the two mobile operators to check to see if there were any recent domestic call records to this phone number. It was impossible for Song Zhilei to go overseas for five days without talking to him. When his wife and children contacted him, Li Mu was sure he would call! So we will definitely find out the clues! It is even possible to directly find out the mobile phone used by Song Zhilei!
Everyone is aware of this, and everyone is waiting with bated breath in excitement. When the technicians of the two mobile operators enter the numbers and instructions, their fingers are shaking nervously, because everyone knows that success or failure may That’s it in one fell swoop!
A minute later, the person from China Unicom was the first to shake his head: "We have compared it here, and there is no such thing."
After another minute, the mobile person said: "Although we have it here, it is a call record from a few months ago. The person who made the call was Song Zhilei's mobile phone number with four 8s. In addition, these recent calls Haven’t had it for months.”
The criminal investigation expert from the public security department immediately said: "Would you like to ask the fixed phone service provider to help with the investigation?"
Li Mu shook his head: "On the one hand, I don't believe that Song Zhilei would risk finding a landline to make a call. On the other hand, what we need is his real-time location! What problem can a landline solve?"
A programmer's logical thinking once again silenced everyone. Li Mu was right. What he wanted was the real-time location, not the location of the landline phone in Australia that Song Zhilei called at a certain time!
Li Mu was in extra pain at the moment, and the fire of hope that had just been ignited in his heart was extinguished again, which made him extremely unwilling.
There must be a way... I must have missed something... He will definitely contact his wife and children, there is no doubt about it, and there must be nothing about the landline, he must have a mobile phone! A mobile phone that you can use to call your wife and children at any time!
Li Mu was hunched over the table, holding his hair with both hands and thinking hard. His brain felt like it was going to explode at the moment.
In his brain, countless keywords came one after another like a barrage filling the screen, but the biggest keyword was mobile phone!
Li Mu immediately felt as if he had caught some clues, but he couldn't figure it out for a while. Now the clues revolved around Song Zhilei's wife and children, and they flew across the ocean to Australia. There were more elements, making it more complicated to sort out.
cell phone!
cell phone! !
cell phone! ! !
Just when Li Mu was about to go crazy, the barrage in his head suddenly exploded into pieces. He straightened up and said in a somewhat crazy voice: "Mobile phone! Mobile phone! That's right!!"
Everyone looked at Li Mu's crazy look and knew that he was thinking about a problem. No one dared to say a word to disturb him.
Five minutes later, Li Mu suddenly walked quickly to the whiteboard in the corner of the conference room and wrote six words on the left and right sides of the whiteboard.
Left: Domestic---mobile phones, landlines;
Right: Abroad---mobile phones and landlines.
Then, Li Mu pointed to the words mobile phone and landline in the domestic column on the left, and said loudly to everyone: "First of all! One thing I can be sure of is: Song Zhilei will definitely contact his wife and children abroad! In other words, domestic There must be a line connecting the two columns between mobile phones and landlines, and foreign mobile phones and landlines!”
Everyone nodded.
For a man, if his wife and three children went abroad and he was kidnapped at home, it is absolutely impossible for him not to keep in touch with his wife and children. This is human nature.
Li Mu added: "The second thing I can confirm is that Song Zhilei must be using a mobile phone in China! It can't be a landline!"
After that, Li Mu put a cross on the landline phone in the domestic column on the left.
Then, Li Mu pointed to the words mobile phone and landline in the foreign column on the right, and continued: "We have just checked, and no domestic mobile phone has been in contact with the foreign landline recently, but based on what we just said According to the inference, there must be a connection between domestic and foreign countries. Therefore, the only possible contact method is the domestic mobile phone and the foreign mobile phone!"
After Li Mu said this, he drew a line between "mobile phone" and "mobile phone" under the domestic and foreign columns on both sides!
Everyone still nodded in agreement.
The operator's technician said: "But we have no way to know the phone number of the foreign mobile phone..."
A smile that he hadn't seen all day finally appeared on Li Mu's face. He said, "It doesn't matter if you don't have a phone number. I will use a programmer's logic today to find this bastard!"
As soon as these words came out, everyone became very energetic.
Li Mu said to the technical staff of the two operators: "From now on, you will implement my requirements step by step."
"no problem!"
Li Mu nodded: "First of all, I want the records of all your calls to Australia in Yanjing and Shanghai in the past six days."
Although both companies now support international long distance, the cost of international long distance communication is very expensive, so Li Mu can be sure that, let alone taking out the call records of calls to Australia from Yanjing and Shanghai, even the six Even if we take out all the records of the day, there may not be tens of thousands of them! Song Zhilei's phone number must be among them!
A few minutes later, the results came out.
In the past six days, China Mobile users in Yanjing and Shanghai had more than 2,000 call records to Australia; China Unicom had more than 1,000 calls;
Li Mu added: "Now screen it and delete all the phone numbers that have only been called once in the past six days. Song Zhilei has made such a big noise in the country. What worries him most is his wife and children. It is impossible to just call him in six days." One phone call.”
Everyone immediately caught the inspiration, and the operator's technical staff also began to conduct the first detailed screening.
Most users who called Australia in the past six days only called once, so the vast majority were screened out this time.
There are still more than 170 mobile users; there are still more than 120 China Unicom users;
There were a total of three hundred people left, and everyone was excited! Because everyone has an intuition that the mobile phone number used by Song Zhilei is among these 300 people! The scope has been reduced a lot!
At this time, Li Mu also became excited and continued: "I speculate that Song Zhilei must have changed his mobile phone number before sending his wife and children on the plane, and then told his wife the new mobile phone number in advance and warned his wife when she arrived in Australia. Use the local mobile phone to contact him at this number instead of using the landline at home. Therefore, I speculate that Song Zhilei’s current mobile phone number is most likely bought in Shanghai, so we first try to contact the users in Yanjing Also temporarily eliminated!”
Technical staff immediately conducted a second fine screening.
This time, only local users in Shanghai who have called Australia more than once in the past six days will be retained.
China Mobile has 90 people left, and China Unicom has only 70 people left.
There are still 160 target users left!
Everyone's palms were covered with sweat. Song Zhilei's whereabouts were getting closer and closer to them!
Li Mu adjusted his breathing a few times, and then said: "Also, Song Zhilei must be in Yanjing now. There is no doubt about this. Doesn't your base station keep roaming records? Okay, let me filter out the 160 users. , how many people have wandered into Yanjing in the past six days!"
genius! ! !
Gu Jianghe almost burst into laughter upon hearing this!
Is the logical thinking of Internet people so abnormal? Using such a seemingly illusory method, gradually increasing the screening conditions and narrowing the screening scope, each condition is like a test with a passing rate of less than half. Test after test, only a very small number of people can be left in the end. At that time, even if we tracked all the people who were finally selected, it would be 10,000 times easier than finding a needle in a haystack!
The conditions for this round of screening are extremely stringent:
1. Local users in Shanghai;
2. Have made international long distance calls to Australia more than once in the past six days;
3. In the past six days, I traveled to Yanjing.
After the third round of screening, there are 8 people left from China Mobile and only 3 from China Unicom!
Gu Jianghe blurted out: "Investigate these eleven mobile phone numbers immediately and locate them all!"
"Wait!" Li Mu stretched out a hand to interrupt, and said: "Screen again! This time among these 11 people, filter out the users who roam directly from Shanghai to Yanjing, leaving only those who travel by land, People who wander through various provinces and cities to Yanjing!"
Everyone's eyes are red! Fuck! This guy is truly a genius among geniuses! Simply amazing!
Gu Jianghe and all the criminal investigation experts were also completely convinced! They were shocked and shocked, and at the same time sighed in their hearts: Every filtering condition of Li Mu was indeed perfect!
Song Zhilei had lost all his records six days ago, and civil aviation had no record of his flight to Yanjing. This meant that he must have come to Yanjing by land, either by driving directly, or by car or train.
If it is a plane, after boarding the plane in Shanghai, no matter it is turned off or not, there will be no signal in the sky, and when there is signal on landing, it will already be Yanjing, so it is impossible for him to fly in Nansu Province, Huizhou Province, Qilu Province Save any roaming records.
However, if he had traveled by land from Shanghai to Shanghai, there is no doubt that he would have left records of his travels in various provinces and cities along the way! Therefore, this filtering condition can continue to narrow down the scope among 11 people!
Everyone held their breath at this moment. China Unicom's technician was the first to say: "We don't have it here. All three of them left the network in Shanghai and reconnected to Yanjing. The interval time is also consistent with the flight time. , so it’s certain that they all come by plane.”
The pressure on China Mobile's side suddenly felt huge. After a while, the technicians of China Mobile almost shouted in excitement: "It's out! It's out! There is only one user who meets all Mr. Li's filtering conditions! This number is China Telecom who has opened international roaming. The name card was just activated in Shanghai seven days ago! In the past five days, he made 11 calls to Australia! Everything is highly consistent!"
Li Mu kicked the whiteboard stand in front of him to the ground and threw the whiteboard pen in his hand to the ground. At this moment, he burst out all his suppressed emotions and yelled with red eyes: "Fuck! This number is absolutely amazing. he!"
