Just when Zhao Hua and Zhang Lei went to T City to investigate Jin Enpei's past, Li Lei and their ticket purchase system in S City found that Jin Enpei was on the 16th of the first lunar month, that is, on the first day of March in the solar calendar, Jin Enpei bought a train ticket from T City to S City, but, what makes people feel strange is that Jin Enpei bought the ticket correctly, but she neither checked in T City nor applied for a refund.

According to the police investigation of the surveillance video of the railway station in S City on the same day, Jin Enpei did not appear at the railway station in S City on March 1, and Lu Xing did not see Jin Enpei after checking the surveillance video from March 1 to March 3, so it shows a problem, before Jin Enpei disappeared, she did not take the train to S City.

If that's the case, then why did she buy a train ticket from T to S? If you bought a ticket, why don't you get on the bus? This point made everyone deeply puzzled and puzzled.

At this point of investigation, a question arises in front of everyone, whether Jin Enpei was taken away by the murderer in T City, or was he taken away in S City, if the gangster kidnapped Jin Enpei in T City, then why did he come to S City to send mail to Xu Lang after cutting off Jin Enpei's palm? Isn't it okay for him to send the mail directly in T City? Why do you want to do more? If the gangster kidnapped Jin Enpei in S City, then where did he kidnap Jin Enpei, and when did Jin Enpei arrive in S City? What kind of transportation did she take to S City? They don't know about these Xu Lang for the time being.

Li Lei told Zhao Hua, who was still continuing his investigation in T City, about his investigation in S City, and asked them to investigate the railway station in T City to see if they had seen Jin Enpei himself from March 1 to March 3.

Zhao Hua and Zhang Lei did not hesitate, and immediately contacted the police in T City, and they came forward to communicate with the railway station, and then they checked all the surveillance videos in the monitoring room during the three days, hoping to find Jin Enpei in the flow of people getting on and off the bus.

Time passed bit by bit, and everyone's hearts began to become anxious, because everyone was worried about one thing, whether Jin Enpei was still alive?

From Xu Lang received the express package to now, three days have passed, in these three days, the clues found by the police can basically be said to be very few, Ye Xuefei told everyone one thing when the autopsy of the palm was carried out, this palm was cut off a week ago, that is, between March 1st and March 5th, Xu Lang received the package on March 10th, and now it is March 13th, so much time has passed, There may be little hope that Jin Enpei is still alive.

Moreover, to everyone's surprise, since the gangster sent a courier to Xu Lang four days ago, there has been no news and action, and there has been no major case in S City during this time, Xu Lang has stayed in the Public Security Bureau for the past few days, has not gone out or gone home, and the murderer seems to have forgotten Xu Lang.

The murderer can forget Xu Lang for the time being, but Xu Lang can't forget the gangster, because there is still a hostage in his hands now, although Xu Lang also knows very well in his heart that Jin Enpei's hope of still being alive is very slim, but Xu Lang just doesn't want to give up.

On the fourth day, Zhao Hua and Zhang Lei, who had stayed up for two days and two nights in T City, called Xu Lang and them in the morning, telling them a message that they didn't know if it was good news or bad news, Jin Enpei did appear at the train station in T City on March 1, but when she entered the train station and waited for the train, she waited for about ten minutes, she seemed to be stopped, and then she came to a monitoring blind spot, and after that, Zhao Hua and they saw Jin Enpei leave the train station, Flagged down a taxi and left.

During this period, Zhao Hua and Zhang Lei repeatedly watched the surveillance video at that time, but they didn't see who the person chatting with Jin Enpei was, and they didn't even know whether the other party was male or female, tall or short, fat or thin, because the surveillance did not capture this.

After that, Zhao Hua and they found the driver of the taxi according to the license plate number of the taxi photographed by the surveillance, the driver was a forty-year-old uncle, surnamed Wu, Master Wu told Zhao Hua that on the day of March 1, he did pull a girl who was very similar to the photo of Jin Enpei that Zhao Hua showed him, when the girl got into the car, her face was very anxious, as if she had encountered some big trouble, after the girl got in the car, she asked Master Wu to drive the car towards the bus station, and finally, Master Wu sent the girl to the bus station in T City, and after that, Master Wu didn't know.

Zhao Hua After they knew this, they came to the bus station in T city, but when they came to the bus station, they had a headache, first, the monitoring of the bus station in T city does not look very perfect, and second, the bus station does not need an ID card to buy a ticket, and you can get on the bus if you give money.

However, the difficulty is a little more difficult, Zhao Hua and Zhang Lei, with the assistance of the police and comrades at the bus station in T City, still retrieved the surveillance video of the day of March 1, according to the surveillance video, at more than 10 o'clock in the morning on March 1, Jin Enpei did appear at the bus station with a suitcase and a backpack, and after she entered the bus station, she immediately went to buy a ticket, and then entered the entrance of the station.

When Zhao Hua saw this, he asked, "Where does this window go?" ”

After taking a look, the person in charge of the bus station immediately said: "This is the window to S, Z, and Y." ”

Hearing what the person in charge said, Zhao Hua and Zhang Lei understood that Jin Enpei was going to S City by car from T City, no wonder Jin Enpei's whereabouts could not be found at the train station.

Although I know what tools Jin Enpei took from T City to S City, there are two doubts that cannot be explained for the time being.

The first suspicion is, who was the person who shouted at Jin Enpei at the train station at that time? Does Jin Enpei know him? If so, who would he be? If you don't know, why did Jin Enpei leave the train station later?

The second suspicion is what kind of information did Jin Enpei get at that time, so that she could give up the slightly slower train and choose a relatively fast car, and even, Jin Enpei did not choose to refund the ticket at that time, this information is the key.

When Zhao Hua and Zhang Lei passed the news to the second criminal investigation team of S City, Ning Yanran immediately arranged for someone to go to the bus station in S City, but unlike T City, whether it was the bus station in S City or the railway station, there were two, one in the east district and one in the west of the city, which was the place where Jin Enpei got off? For the sake of insurance, Ning Yanran asked Li Lei and the others to go to both places to have a look, and by the way, they brought back a copy of the surveillance video.

During this period, Ning Yanran also contacted the communication company and retrieved Jin Enpei's communication records for the past three months, Ning Yanran carefully checked Jin Enpei's communication records after getting them, and as a result, in the three months of communication records, the communication time and frequency of the first month and the second month were very large, and the people who communicated were not the same, and the third month was the same at the beginning, but in the back, these became much rarer.

Ning Yanran looked at the phone numbers in the communication record, Ning Yanran was the first two big, and she was helpless, so she still checked the phone number one by one according to the communication record.

After some investigation, Ning Yanran found that among these many phone numbers, most of them were calls from customers of Lang Ge Detective Agency, followed by calls from Xu Lang and several of them, and finally, some harassing calls and spam text messages, etc., in the past three months, Anding Hospital in T City, that is, the hospital where Jin Enpei's mother Yu Duyun is located, every other week Jin Enpei will make a phone call over there, and the call time is generally more than half an hour, after Jin Enpei returned to T City, This kind of phone frequency is gone, and until now, it has not been seen again.

According to the communication records, she couldn't find any useful clues, so Ning Yanran had to put the line of communication records aside for the time being, and again, Ning Yanran didn't ask the comrades who hadn't asked the technical department, now that the level of science and technology is so developed, there should be a way to use technical means to lock Jin Enpei's mobile phone, so as to find Jin Enpei's location.

Hope is good, when Ning Yanran told the technical department about this idea with great expectations, the comrades of the technical department directly poured a scoop of cold water on Ning Yanran, because, according to their experimental findings, Jin Enpei's mobile phone and mobile phone card are in a state of separation, which means that Jin Enpei's mobile phone card was unplugged and lost, and the mobile phone was also destroyed, and there is no way to determine Jin Enpei's location through the mobile phone and the phone card.

After Ning Yanran's opinion was also rejected, Ning Yanran's head became bigger and bigger, and Li Lei and the others brought back the surveillance video of the two bus stations in S City on March 1 and handed them over to Lu Xing, and they stayed at the two bus stations to inquire and investigate, to see if any staff working at the bus station had seen Jin Enpei on March 1.

After Lu Xing got those surveillance videos, he started the quick check mode, he first watched the surveillance video of the bus station in the east of the city, Lu Xing did not find Jin Enpei's voice after a quick browsing, which made Lu Xing a little disappointed, and when he changed the hard disk to check, Lu Xing rubbed his astringent eyes and yawned.

Hard work pays off, when Lu Xing was watching the surveillance video of the bus station in the west of the city, sure enough, at about half past one in the afternoon of March 1, he saw Jin Enpei at the exit of the bus station, in the video, Jin Enpei pulled a suitcase, straddled the backpack diagonally, and then tilted his head sideways, as if he was talking to something, Lu Xing also found in the monitoring that Jin Enpei got off the train from the station, and there was a person wearing a black sweatshirt, a peaked cap, and a mask on her face, and it was not clear in the video whether this person was male or female. His height is almost the same as Jin Enpei, and he seems to know where there is a surveillance probe, he almost hides himself in the crowd, even if he is occasionally photographed by the surveillance probe, he keeps his head down or the surveillance will shoot his face.

Lu Xing followed the monitoring all the way and found that after Jin Enpei got out of the bus station, he stopped a taxi, got into the taxi with his suitcase, and where he went after that, Lu Xing didn't know for the time being, and the person in the black sweatshirt disappeared with the flow of people when Jin Enpei left the station, however, when Lu Xing saw Jin Enpei get into the taxi, he didn't see the person get into the taxi, so Lu Xing can be sure that Jin Enpei is the bus station where he left by car.

After watching these videos, Lu Xing did not need Ning Yanran's arrangement, he contacted the traffic department and the monitoring department, and retrieved all the surveillance videos from the vicinity of the bus station in Chengxi District on March 1, because he wanted to find out where Jin Enpei went by taxi according to the surveillance video, because the bus station in Chengxi District photographed the license plate number of the taxi that Jin Enpei took when he left, so Lu Xing was extremely relaxed in the later investigation.

After Lu Xing got the surveillance video, at the beginning, he found that the taxi was carrying Jin Enpei towards Xu Lang's Langge Detective Office, but when the car was halfway through, at a traffic light, the car suddenly turned around and drove towards the outside of the city, Lu Xing followed the surveillance video all the way down, but the monitoring was no longer in the suburbs, because it was outside the suburbs, and no monitoring probes were installed, and Lu Xing temporarily lost Jin Enpei's traces.

After Lu Xing told Ning Yanran and Xu Lang about the results of his investigation, he continued to check the previous surveillance video.

According to the surveillance footage, the following things can be determined.

First, Jin Enpei arrived in S City at about 1:30 p.m. on March 1, and during this period, she was still safe.

Second, Jin Enpei wanted to go back to the company at first, but he suddenly changed places, and something must have happened in it.

Third, who is the person wearing a black sweatshirt with a black cap and a mask who appeared next to Jin Enpei? Is he the murderer who took Jin Enpei? Is he the one who sent the mail to Xu Lang? I don't know yet.

After the investigation was here, Ning Yanran immediately arranged for someone to go to the taxi company, found the taxi driver according to the taxi license plate number captured by the surveillance, and asked him about the situation at that time.

The communication records have always been there, Ning Yanran did not have any trouble finding it, sure enough, between half past one and two in the afternoon of March 1, between this hour, Jin Enpei received a total of three calls, made a call, and received two text messages, according to the phone records, these three calls, including one call from Du Ziqiao, and then the two clients of the firm called Jin Enpei, their call time was very short, most of them were only about one minute, and Du Ziqiao's was even shorter, with less than thirty seconds of call timeAs for Jin Enpei's own call, it was she who called Anding Hospital, and it should be looking for Yu Duyun, as for the two text messages, one of them is a text message sent by a communication company, which should remind Jin Enpei that he has arrived in the S municipal district, and the other text message is sent from an unfamiliar number.

Ning Yanran saw this, immediately picked up the mobile phone, dialed the number, Ning Yanran, who was still hopeful, not long after she pressed the dial button, she put down the mobile phone with a black face, obviously she didn't get through, I don't know if it was turned off or stopped, and there was just a busy sound that couldn't be connected.

If you only look at the communication records, before Jin Enpei completely disappeared, the last few people she contacted should be Du Ziqiao of Langge Detective Agency, two customers who have business dealings with the detective agency, and one is Anding Hospital in T City, these people have been gradually ruled out of suspicion in the previous investigation, whether it is Du Ziqiao or the two customers who called Jin Enpei, they did not appear near the bus station on March 1, Du Ziqiao is a local, he was before the fifteenth day of the first lunar month, has already started to deal with business in the detective agency, and the two customers who contacted Jin Enpei, one is abroad and the other is in the field, neither of them has returned to S City, at least in terms of time, they are not suspected of committing crimes.

According to the communication records, Jin Enpei received this text message at 2:08, and Lu Xing saw that the taxi driver changed the road at 2:11, with an interval of three minutes, so it can be seen that Jin Enpei suddenly chose to change the route, which must have a lot to do with this text message, but unfortunately, Ning Yanran and they couldn't know the content of the text message, otherwise, everything would be simpler.

Of course, after Ning Yanran came to this conclusion, Xu Lang thought of another conclusion, could it be that the taxi driver had a problem? Could it be that he suddenly changed the direction of his travel? As for whether there is a problem with the taxi driver, it depends on whether the police officers who went to the taxi company to investigate have gained anything.

Investigation so far, Xu Lang rarely expresses his opinions, he always feels that Jin Enpei's case is strange in it, as for what is strange, so strange, Xu Lang can't say it for a while, but he always feels that things are very strange, especially, in several investigations, there is a guy who is not tall, wearing black clothes, wearing a black cap, and a black mask, who is this person? Why does he always appear by Jin Enpei's side, Xu Lang has seen the screenshot of this person's surveillance screen, Xu Lang doesn't know this person, whether it is from the body shape or other aspects, Xu Lang can be sure that he definitely doesn't know this person, so who will this person be?
