Although the second criminal investigation team readjusted the direction of the investigation according to the information written on Jin Kaize in the second challenge letter mailed by the murderer, they did not give up the pursuit of Jin Enpei's whereabouts before his death.

Lu Xing previously investigated Jin Enpei at the bus station in the west of the city according to the Tianyan system, and then stopped a taxi at the exit of the bus station, Jin Enpei originally planned to go directly to the staff dormitory of the detective firm, but she asked the driver to change direction halfway, and the taxi carried Jin Enpei out of S City, drove out of the city, left the city, and entered the suburbs that could not be covered by the Tianyan system, thus losing his whereabouts, and the taxi driver never appeared again, knowing that someone mailed a package to Xu Lang, None of the taxi drivers were in sight.

According to the police investigation, the taxi driver with the tail number 783 is named Pang Yuanqing, male, 42 years old this year, slightly fat, married, has a son who is in high school, and a wife who works in a certain company, Pang Yuanqing has been a taxi driver for 12 years, and can be called an experienced old driver.

Pang Yuanqing in the taxi driver in the past 12 years, work has been diligent, because his wife often has to work night shifts, so he has always been a daytime shift, in these years, Pang Yuanqing has assisted the police to arrest a burglary and wounded criminal, so the police gave commendations and awards, Pang Yuanqing once also because of the rescue of children in the river who fell into the water, was reported by the media, and Pang Yuanqing himself was also selected by the taxi company as the best brother.

In fact, before Xu Lang received the package, Pang Yuanqing's wife had gone to the police station to report the case, but Pang Yuanqing's wife needed to rest during the day and work night shifts at night, the husband and wife rarely had a lot of time to meet, at first, she didn't feel strange, after all, it was only after the New Year, and S City is a very developed city, after the fifteenth day of the first month, a large number of migrant workers returned to S City to continue working, she thought that Pang Yuanqing was to pull a few more orders, so she went home late every time.

In addition to the fact that it has only ended the New Year, there is also a point that their son is about to graduate from high school and is about to take the college entrance examination this year, which is the time to use money, so Pang Yuanqing's wife Tang Feifei often works overtime in the company, and the two of them have less time to meet.

Tang Feifei found out on March 7 that Pang Yuanqing hadn't been home for a long time, it happened to be Sunday, and it was a holiday, so Tang Feifei was at home on vacation, and their son just came back from school, she originally planned to discuss with Pang Yuanqing and let Pang Yuanqing take her and her son out for a day, after all, her son is about to take the college entrance examination, take her son out to play before he has officially entered the review stage, and when his son officially enters the review stage, there will not be so much time, but at this time, she suddenly found that her husband Pang Yuanqing had not come home for a long, long time.

At first, she thought that Pang Yuanqing's company was too busy, so she called the taxi company to inquire about the situation, however, to her surprise, the leader of the taxi company was also very strange, because Pang Yuanqing had not come back since he went to the taxi company on March 1 to drive the taxi away, whether it was to call Pang Yuanqing's mobile phone, or to use the call station inside the taxi, they couldn't contact Pang Yuanqing, they also thought that Pang Yuanqing took an order to go to other places, or to rest at home. In addition, the company has been very busy recently, so they didn't pay too much attention to this matter, and when Tang Feifei called to inquire, they realized that something was wrong, so they went to the local police station to report the case.

After receiving the report, the police at the police station could not accurately say when Pang Yuanqing lost contact because of the taxi company or Pang Yuanqing's wife Tang Feifei, so after the police station made a record for them, they asked them to go back and wait for news, and the comrades of the police station also started an investigation according to the situation they currently have, but after a simple investigation was fruitless, they encountered other criminal and civil cases, so they temporarily gave up the investigation of Pang Yuanqing. For the time being, the case of Pang Yuanqing's disappearance was treated as a missing case, and it was not until the second criminal investigation team investigated Pang Yuanqing because of Jin Enpei's case that they really began to pay attention to this case.

Following the information of the Tianyan system, it was Bao Chen of the first criminal investigation team who was responsible for tracking down the taxi driver Pang Yuanqing, and after he got Lu Xing's information, he came to the taxi company where Pang Yuanqing was located and asked about Pang Yuanqing's specific situation.

According to the recollections of the relevant staff of the taxi company, Pang Yuanqing began to return to work at the taxi company on the fifth day of the first lunar month, according to people familiar with Pang Yuanqing, Pang Yuanqing did not have anything abnormal after returning to work after the New Year, he just took a half-day off on the ninth day of the first lunar month, and the reason was very simple, that is, because he sent his son to S High School to go to school, he took leave in the morning and came back in the afternoon to continue to work, and other than that, Pang Yuanqing did not have any abnormal situation.

When Pang Yuanqing lost contact, it was March 1st, that is, the sixteenth day of the first lunar month, on March 1st, Pang Yuanqing came to the taxi company to clock in and go to work as usual, and exchanged work with the night shift driver, there was nothing abnormal, and according to Pang Yuanqing's companion, that is, the night shift driver who was responsible for driving the car with Pang Yuanqing, Pang Yuanqing was still very happy when he came to the company that day, and Pang Yuanqing was no different from usual.

Moreover, the first person to find out that Pang Yuanqing was missing was not Pang Yuanqing's wife Tang Feifei, but the taxi driver who worked the night shift, he came to the taxi company the next day, that is, at half past five in the evening on March 1, when he was ready to take over the shift, he saw that other taxi drivers who opened the day shift had opened the car to the company for the handover, and Pang Yuanqing had not come back for a long time, he was a little worried and confused, however, it is normal for the taxi driver to not be able to take over the shift on time and on time, after all, taxi is a service industry, Sometimes when the handover is approaching, it is normal for guests to be pulled in later, so he waits until seven o'clock in the evening, Pang Yuanqing has not come back, he is a little impatient and anxious, so he dials Pang Yuanqing's mobile phone.

According to his recollections, the first time he called Pang Yuanqing's mobile phone was around a quarter past seven, at that time, Pang Yuanqing's mobile phone was still connected, and after Pang Yuanqing received the call, he first said sorry on the phone, saying that he had taken a passenger out of the city and wanted to go to the countryside, and now there is no way to come back.

The driver heard that Pang Yuanqing was going to the countryside, and the doubts and incomprehension in his heart suddenly disappeared, after all, taxi drivers sometimes pull passengers to the countryside, at that time, on the one hand, he was for Pang Yuanqing's safety, on the other hand, it was also a joke between friends, he asked Pang Yuanqing on the phone to be careful, don't be robbed and so on, Pang Yuanqing was on the phone at the time, and told him with a smile that he was not pulling a tall man, but a very young and beautiful woman, after that, Because taxi drivers can't talk on the phone for a long time while driving, their calls quickly hang up, and the talk lasts about a minute to two minutes.

When Bao Chen asked him if he had asked Pang Yuanqing where he was going to drive the car to the countryside, the driver shook his head, and he said with great annoyance: "No, I didn't pay much attention to it after I heard him say that he pulled a young and beautiful female passenger, and besides, Pang Yuanqing is still an old driver, and he won't pull any abnormal guests." ”

When Bao Chen heard this, he first nodded, and then shook his head in disappointment.

According to the police investigation of Pang Yuanqing, Pang Yuanqing's family is very harmonious, and the relationship between him and his wife Tang Feifei has always been very good, although the husband and wife one goes to the day shift and the other works the night shift, and they often can't see each other, and there will be quarrels on weekdays because of some trivial things in the family, but, overall, the relationship between the two people is still very good, as for their son, they are also very competitive, and their grades have always been in the top ten in the class. As long as you play normally, the possibility of being admitted to a key university is very high, even if you fail to get admitted to the university in your mind, at least there is no problem in going to a better university, as for Pang Yuanqing's relationship in the company, according to the memories of colleagues in the taxi company, it is said that Pang Yuanqing is a very good man, kind-hearted, warm-hearted, always with a smile on his face, he smiles when he meets people, he is the kind of person who gets along very well, Pang Yuanqing has a good relationship with his colleagues, after all, everyone is a brother who opens a taxi, and everyone is dragging his family, People who come out to drive to make a living, it is not easy for each other, there will be no contradictions, and the brothers who drive taxis are more grouped, so this situation will not occur.

After Bao Chen's investigation came here, they basically ruled out the suspicion that Pang Yuanqing was kidnapping Jin Enpei, but for the sake of prudence, they still investigated Pang Yuanqing's economic conditions.

Pang Yuanqing is a native of S City, and Tang Feifei is a foreigner, Pang Yuanqing and Tang Feifei relied on their savings for many years to buy a two-bedroom house in S City, although the house is not big, but it is very warm, Pang Yuanqing drives a taxi, and his monthly income is also very good, and although Tang Feifei's income is not as much as Pang Yuanqing, it is not bad, the monthly income of the two of them adds up to maintain the daily expenses of a family of three is no problem at all, and when the police are investigating their savings, found that the two of them already had a small savings of 200,000 yuan, and the money was intended for their son to go to college, and the rest was for his son to start a business or buy a house after graduating from college.

The police conducted a detailed investigation of this deposit and found that the deposits of more than 200,000 yuan were all deposited by Pang Yuanqing and Tang Feifei little by little over the years, and the income was completely normal and legal, and there was no unknown source.

The police investigation has ruled out the suspicion of killing people for money, and it is impossible to kill people with passion caused by emotional problems, so could it be an intention? After all, Jin Enpei's appearance, the police officers of the first criminal investigation team and the second criminal investigation team have all seen it, and they know that Jin Enpei looks very good, and she is the kind of woman who attracts attention, but when investigating Pang Yuanqing, according to the testimony of Pang Yuanqing's wife and his colleagues, Pang Yuanqing is definitely not that kind of person, therefore, the suspicion of the crime caused by the intention of seeing the color is also excluded, so the next thing is to solve a problem, where is Pang Yuanqing now?

Only by finding Pang Yuanqing can we know where they went with Jin Enpei on March 1st, and what happened on March 1st, because the last person Jin Enpei saw before her death was likely to be him besides her murderer.

Jin Enpei's murder and Pang Yuanqing's disappearance, there must be some kind of connection between the two, Xu Lang After they got this information, everyone had a very bad premonition, that is, Pang Yuanqing was very likely to have been killed.

This speculation is very bad news for both Pang Yuanqing's family and the police, and now finding Pang Yuanqing is the key to unraveling what happened in the period before Jin Enpei was killed.

If you want to find the missing Pang Yuanqing, you have to know the last place where he appeared, but the Tianyan system finally photographed the taxi driven by Pang Yuanqing appearing in the surveillance screen, which was going to Miri Road in the north of the city.

After Bao Chen returned to the Public Security Bureau and reported the information he had investigated to Wu Yong and Xu Lang, Xu Lang took a map of S City and surrounding cities, and everyone gathered around the map to check it.

S city is a city with very developed transportation, S city faces the sea in the south, Y city in the east, P city in the west, T city in the north, and Miri Road is the last important road in S city from the urban area to the suburbs, and the east and west of the city are different, the terrain in the north of the city is very complicated, because in the north of the city, most of them are rural, suburban, the terrain here is complex, the population is large, and it is a place where the foreign population and the local population live together, there are many villages and towns here, suburbs, villages, There are at least dozens of places in the township, and although the population is not as dense as the urban area of S City, it is also quite populous.

Miri Road is the only road in the urban area of S City to reach the north of the city, after Miri Road, it is the road of urban and rural areas extending in all directions, these roads can go to every place in these villages, and the car can go to the west or east of the city along the outer ring road after leaving Miri Road, so as to go to Y city or P city, these are all OK.

And the last place where Pang Yuanqing and Jin Enpei disappeared was in the area of Miri Road, it is very difficult to know which road Pang Yuanqing and they took from such a complex terrain, I don't know which of these dozens of places they went, I don't know where they disappeared, so they can't find Pang Yuanqing and his taxi, in addition, there is another point that has attracted everyone's attention, that is, the north of S City is next to T City, and T City is Jin Enpei's hometown, If you don't take a train or other means of transportation, you can drive from S city to T city by car, Miri Road is a must, so now there are several possibilities.

First, Pang Yuanqing may have carried Jin Enpei to a certain village or township in the northern part of the city, where they were held hostage by gangsters.

Second, after Pang Yuanqing and the others left Miri Road, they did not continue to stay in Chengbei District, but drove directly to T City.

Third, Pang Yuanqing and the others may have transferred to Chengdong District from here after leaving Miri Road, as for whether they stayed in Chengdong District or went to Y City, they still need to investigate to know.

Fourth, they transferred to Chengxi District, as for whether they stayed somewhere in Chengxi District, or went directly to P City, this also needs to be investigated.

In short, the police have come to these four conclusions based on the information obtained from the current investigation.

After Xu Lang came to these four conclusions, he first ruled out the third and fourth possibilities, the reason is very simple, if the murderer is kidnapping Jin Enpei and them in the west or east of the city, then there is no need to let Jin Enpei and them take a detour to come here, it is completely possible after Jin Enpei leaves the bus station in the west of the city, the murderer can directly let Jin Enpei take a taxi to go directly to a place in the west of the city, it is simple and troublesome, there is no need to come around the bend, and the same is true in the east of the city. If the murderer planned to kidnap Jin Enpei from the beginning and kill her, it would have been possible for Jin Enpei to buy a bus ticket to the eastern district of S City in T City, and there was no need to go to such great lengths to do these things.

Judging from the murderer's understanding of Xu Lang and Jin Enpei, it is impossible for him not to know the existence of the Tianyan system, every time Jin Enpei appears in the monitoring probe, he will have one more chance of exposure, which will allow Xu Lang and the police to follow the Tianyan system to find her, of course, if the murderer did this on purpose, in order to disrupt the direction of the police's detection, it is another matter, however, this possibility is also very small.

After ruling out the third and fourth possibilities, Xu Lang focused on the first and second possibilities, so the question arises again, did Jin Enpei stay somewhere in the suburbs and towns of Chengbei District, or did they go directly through Chengbei District and return to T City? This is the focus of their next investigation, however, no matter what the possibility, the police need to conduct a visit to the north of the city to see if they have seen or encountered the taxi driven by Pang Yuanqing, after all, taxis are different from other cars, each taxi has fixed signs and characteristics on it, if someone sees it, it will be very eye-catching, so Ning Yanran and Wu Yong asked the people of the first and second criminal investigation teams to contact the police of the police station in Chengbei District to visit and investigate Chengbei District together, while Xu Lang stayed in the Public Security Bureau.
