After the first and second criminal investigation teams left one after another, Xu Lang sat alone in front of the map, looking at the map in front of him.

Compared with the possibility of Jin Enpei staying in Chengbei District, Xu Lang is more inclined that Jin Enpei returned to T City by car again, if Jin Enpei stayed in Chengbei District, she didn't need to go over with so much luggage, after all, according to the surveillance screen, when Jin Enpei temporarily changed his mind and asked Pang Yuanqing to drive to the outskirts of the city, the taxi was less than 20 minutes away from the staff dormitory of the detective agency. It's okay to put your luggage and other things down and go again, after all, it's very inconvenient to run around with a large bag and a small bag.

If Jin Enpei is going back to T City, then she will go with her luggage, but why didn't she choose to go to the bus station to take the bus back? Instead, choose a taxi that costs a lot of money?

Although the taxi will not be charged according to the meter when it runs long distances, but from S city to T city, it will cost at least thousands of yuan to run down, although thousands of yuan is not much, but for a person who has only been working for a long time, this is not a small amount, and it is not long after the New Year, does Jin Enpei have to rush back to T City?

However, in Lu Xing's investigation, it was already afternoon when Jin Enpei came to S City, but according to Xu Lang's memory of the departure schedule of the bus station, the last shuttle bus from S City to T City should be around 6 o'clock in the afternoon.

If everything is really as Xu Lang guessed, what happened to Jin Enpei's hometown?

"Smack"

Xu Lang took out a cigarette and lit it, he was thinking while smoking, suddenly, Xu Lang remembered one thing, Jin Enpei actually has no relatives in T City, her father Jin Kaize died when she was very young, the only one who remains in T City is Jin Enpei's mentally ill mother Yu Duyun, if Yu Duyun has an accident, then Jin Enpei rushed back in such a hurry to explain the past, in this way, Jin Enpei's last whereabouts should be in T City instead of S City, but, If this is the case, then a new problem has arisen.

If Jin Enpei was kidnapped by the murderer after returning to T City from S City, then where did the murderer kidnap Jin Enpei? How did he kill Jin Enpei? And what about bringing Jin Enpei's palm and head back to S City?

The palm of the hand is small, and it can be hidden in something and brought from T City to S City, but how did he bring Jin Enpei's head? It is impossible to take a train or other means of transportation that needs to go through the security check, because the palm is small and easy to carry, he can hide somewhere on his body when he passes through the security check, but how can he bring a human head of that size?

If the murderer really came by train or other means of transportation, he would definitely be noticed by the security personnel during the security check, and be interrogated, even if he could pass the security check smoothly, but, in this way, the probability of being found will be greatly increased, because the murderer himself has no way to determine whether he can safely bring Jin Enpei's head over, maybe he will be found when he passes through the security check with Jin Enpei's head, and thus be arrested, as long as he is a normal person, he will not make such a mistake. What's more, he still dared to challenge Xu Lang and provoke Xu Lang and the guys from the S City police.

After thinking about this, Xu Lang thought of two possibilities.

First, Jin Enpei did not return to T City, she was killed when she was still in S City, as long as Jin Enpei is still in S City, then with Jin Enpei's body to S City to mail to Xu Lang, there is no need to take a train or other means of transportation, and there is no need to go through the security check, as for whether he came by his legs, or by taxi or bus or other means, it will not arouse people's suspicion, but this possibility, Xu Lang feels creepy and chilling when he thinks about it, imagine it, How would it feel to be standing or sitting next to you with a head on your back?

Second, Jin Enpei was indeed killed in T City, and the murderer himself owned a private car and other means of transportation, and he drove from T City to S City, and during the peak period of the return trip just after the New Year, whether it was a high-speed or a national highway, he would not conduct a detailed inspection of the inside of the private car, so that he would not run around with a head, or with a corpse, it would not be too much of a problem, and it would not arouse the suspicion of others.

If it is the first possibility, then the Chengbei District that Bao Chen and they will visit next is the key, if it is the second case, then, Zhao Hua can add one when they investigate the people who are familiar with Jin Enpei, that is, the murderer is very likely to have a private car or other means of transportation, in this way, Zhao Hua's investigation work has been reduced a lot, no matter which possibility, the visit and investigation of the Chengbei District, the investigation and mapping work are the focus, as long as Bao Chen and they get the results there, It can be determined whether Jin Enpei was killed in S City or T City, as for Pang Yuanqing's whereabouts, while Bao Chen and the others are visiting and investigating, they will definitely gain something.

————

When Bao Chen and the others went to Chengbei District to conduct a visit and investigation, and carried out the investigation work, Zhao Hua in T City retrieved the car accident files of Jin Enpei's father Jin Kaize, and passed these files to Xu Lang's side through machine scanning and other methods.

Jin Kaize's car accident file is actually not much, and the case 17 years ago is actually very simple.

On the day of the car accident, the driver of the factory did not go to work in the factory because of something at home, and the factory received a large order not long ago, and the other party wanted to be more urgent, and now the other party wanted something finally rushed out, therefore, in the case that the truck driver did not come, Jin Kaize drove the company's truck by himself, carrying the car loaded with parts to the other party. And the car accident happened on the way when Jin Kaize drove to hand in the bill.

Seventeen years ago, the traffic roads in T City, as well as the traffic command, were not as perfect as they are now, when Jin Kaize was driving a truck through an intersection, the red light went out, the yellow light turned on, and Jin Kaize just started the car, and when the yellow light went out and the green light turned on, Jin Kaize just started the car and rushed over a private car from another intersection.

At that time, the speed of the private car was about 12, the result can be imagined, the private car and the truck collided together, the front of the private car was directly smashed, and the truck driven by Jin Kaize was also overturned to the ground, because the incident occurred at the intersection, it was the rush hour after work, many passing cars had to pass here, after the car accident, there was a rear-end collision immediately after, several cars rear-ended over, resulting in the intersection is very chaotic.

When the police arrived at the scene, they moved the rear-end car away to rescue Jin Kaize, and found that the driver's door was completely deflated, and the door could not be opened, and Jin Kaize was wearing a seat belt, and he passed out covered in blood. has been bleeding nonstop, and Jin Kaize is already dying, angry like a gossamer.

When the police finally rescued Jin Kaize and put him in an ambulance, Jin Kaize had already died before the ambulance arrived at the hospital.

As for the private car that collided with the truck driven by Jin Kaize, the front of the car was not only smashed, but also fell off one of the wheels, rolling down to the side of the road, in addition to the driver's seat There was a man who had died on the spot, and there was a woman in her thirties in the co-pilot, the woman was still alive after the police arrived, she was taken to the hospital in an ambulance, and carried out emergency rescue work in the hospital, and finally, although she was temporarily out of danger of life, she was also admitted to the intensive care unit and fell unconscious.

In addition, the police also found a teenager boy covered in blood in the back of the private car, the boy was not too seriously injured, however, because of excessive fright and the collision of the car and temporarily unconscious, he was sent to the hospital not long after, he woke up, however, it may be because of a car accident, the boy's brain was slammed, causing a concussion, or it may have been very frightened, the boy woke up, has been huddled in the corner of the hospital bed, shivering, without saying a word, No matter what the police or the doctors and nurses at the hospital asked, he didn't speak.

The man in the driver's seat of the private car is called Yu Tian, the attending surgeon of the Third People's Hospital of T City, when the Chinese New Year's Eve is five years old, and the co-pilot is his wife, named Lu Qinxuan, who is two years old when the Chinese New Year's Eve, and is a nurse in the same hospital as Yu Tian, and the little boy sitting in the back seat is called Yu Hongxuan, who was nine years old at the time, and is in the fourth grade of the T Small Experimental Primary School.

After conducting an on-site investigation of the scene of the car accident and visiting and investigating the surrounding pedestrians and vehicles, the police in T City learned that the whole process at the time of the accident was a tragedy caused by a private car speeding at 120 yards and running a red light.

It turned out that Yu Tian received a temporary notice from the hospital at that time, and the hospital received a seriously injured patient who was hospitalized and urgently needed emergency surgery, and other surgeons had surgery to do, and it was the doctor's duty to save people, so Yu Tian, who was still on vacation at the time and took his wife and son to the suburbs to play, immediately rushed to the hospital after receiving the notice, and Yu Tian was at that time, because he was not at work, he drank some wine with a few friends, and Yu Tian rushed back to do surgery because he was in a hurry, after all, human life is greater than the sky, Saving people is a race against death, and it needs to be carried out against time, so when Yu Tian took his son and wife back, he drove the car fast along the way, and when he passed through that intersection, he saw that the green light went out and the yellow light turned on, he stepped on the accelerator and was about to rush over, but it collided with Jin Kaize's truck, which caused a car accident.

Although Yu Tian's starting point is good, he was speeding in order to rush back to the hospital for surgery to save people, but he drove the car to 120 yards in the urban area with a speed limit of 50, which was originally a violation of traffic rules, and he also ran a red light and caused a car accident, not only lost his life, but also killed Jin Kaize, and his wife was also seriously injured and hospitalized, and his son was also very frightened, so this case, after some investigation, ended with Yu Tian taking full responsibility. The court tried all the expenses after Jin Kaize's death, and the Tian family bore them, and compensated Jin Kaize's family a sum of compensation.

It's just that Yu Tian died at the time of the car accident, and his wife Lu Qinxuan was still in the intensive care unit at the time, unconscious, as for Yu Hongxuan, he was still very young at the time, he was a minor, and he couldn't make any decisions at all, and the only one who could make a decision was Yu Tian's father Yu Zhen.

Yu Zhen was over 60 years old and was also a doctor, Yu Zhen's wife, that is, Yu Tian's mother, died of illness a few years ago, Yu Zhen had already retired at that time, and the old man who should have enjoyed the joy of family was sent to a white-haired person after the car accident, and he fainted because of excessive sadness at that time, and was hospitalized.

After the results of the trial came out, Yu Zhen looked at his daughter-in-law who was still lying in the intensive care unit, and when he looked at his grandson Yu Hongxuan, whose eyes were not clear and bright, and carefree, the old man's mood could be imagined, but after all, the old man was still a sensible person, he endured the grief in his heart, and after dealing with his son's funeral, he sold the house with his savings over the years, and after making up enough compensation, he handed the money to Jin Enpei's mother Yu Duyun, and after that, Yu Zhen took the rest of the money, Continue to treat his daughter-in-law Lu Qinxuan.

The good news is that after lying in the intensive care unit for more than a month, Lu Qinxuan finally woke up and was out of danger, but in addition to the good news, there is also a very unfortunate news that Lu Qinxuan also suffered serious trauma to his cranial nerves and spine in a car accident, and his lower body was directly paralyzed, and he could only spend the rest of his life in a wheelchair.

Lu Qinxuan was hospitalized for more than half a year, and was also discharged, Yu Zhen left the city of T City with his paralyzed granddaughter-in-law and little grandson, and returned to the countryside, since then, there is no follow-up to this case, after all, the police's job is to investigate the truth of the matter, they are struggling on the front line, facing life and death every day, and have seen too many unfortunate things, although Yu Tian's starting point is good, but at the same time, he chose to save people, but also because of his own fault caused someone to die, The plight of Yu Tian's family is worthy of sympathy, but he has brought a lot of pain and sorrow to Jin Enpei's family.

Xu Lang frowned after reading the information, the cigarette in his mouth never stopped, and the empty ashtray that was originally placed in front of him was now full of cigarette butts.

Seventeen years ago, Jin Kaize's car accident case looked very clear and clear, there was nothing unclear, whether it was the traces and physical evidence at the car accident scene, or the pedestrians who were present at the scene of the car accident, and the testimony of eyewitnesses, there was no problem, this was just a simple car accident, in addition to Jin Kaize's death, Yu Tian's family's unfortunate experience also made people feel sympathetic, Xu Lang did not find anything wrong.

Xu Lang really couldn't figure out why the murderer mentioned Jin Kaize's name in the second challenge letter, if the car accident was caused by Jin Kaize running a red light or speeding, Jin Enpei's death would have passed, and Xu Lang would not be so confused, but the car accident seventeen years ago was not like this, which made Xu Lang confused.

Xu Lang read the archival materials passed by Zhao Hua three times, but still did not find anything suspicious from this case file, even the black and white photos taken back then, Xu Lang carefully looked at it, and still did not find anything wrong.

Whether it is the rescue operation of the police after the car accident, or the subsequent investigation and evidence collection work, it is carried out in accordance with the rules and regulations, there is no dereliction of duty, dereliction of duty, and there is no favoritism, whether it is in the chain of evidence, or in the testimony of witnesses, it is impeccable, it can be said that this is a very simple case, there should be no problem.

If this is the case, why did the murderer lead Xu Lang to re-investigate the car accident seventeen years ago? Is there anything that could not be done in that car accident seventeen years ago?

Xu Lang thought of this, so he picked up his mobile phone and dialed Zhao Hua's phone, and asked Zhao Hua about all the things and details that happened in the car accident seventeen years ago.

Xu Lang couldn't figure out the connection, and Ning Yanran couldn't figure it out, who was the murderer? Why did you kill Jin Enpei so cruelly? Xu Lang stared at the file in front of him and fell into deep thought.
