"How many police officers were escorting the murderer at that time?" Xu Tian asked.

"I knew you would ask this question, everyone will have this question after reading the case file, not to mention that the leader of the team was the elite police officer Lao Chen, who had three police officers under Lao Chen at that time. Mr. Chen had been sitting with the driver in the cab of the truck, while three other police officers were guarding the killer in the back compartment. But what Lao Chen didn't expect was that the tires burst when the truck drove to the wilderness, and the truck driver began to change the spare tire after stopping the car, and during this period, Lao Chen and one of the police officers also got out of the car, just when Lao Chen was standing not far from the back compartment and smoking, the truck suddenly exploded, and the two police officers and the murderer, including the truck driver, were not rescued. Since there was no signal in that area, Lao Chen could not dial the fire alarm, and Lao Chen and the police could not do anything in the scorching fire. At that time, the only thing Lao Chen could do was to hurry up and run in the direction of the county seat, if he was lucky, he could take someone else's car to the area with a signal to call the fire alarm, if there was no good luck, he could only run to the place with a signal. But just when Lao Chen was just starting, the truck actually ignited a second explosion, when the explosion happened to be another police officer passing by the truck, the moment Lao Chen turned around, he saw his subordinates being swallowed in the fire. Li Zhitong said.

"Lao Chen actually experienced this kind of thing?" Xu Tian couldn't believe his ears.

"The matter is not over here, Lao Chen is standing in the middle of the road in a completely helpless situation, and it can be seen without investigation that the ignition of the truck is not an accident at all, it is a targeted attack, and the target is the murderer. But Lao Chen couldn't do anything, there were only two roads in front of him, rushing into the sea of fire and dying in his duties, or running in the direction of the county seat. Li Zhitong said.

"In terms of Lao Chen's character, running in the direction of the county seat means retreating, right?" Xu Tian said.

"But Lao Chen did not rush into the fire, the fire was later identified as a blast caused by ignition of gasoline during the investigation, not the gasoline in the mailbox, a large volume of gasoline was found in the back compartment of the entire truck, and there were other blasting devices." Li Zhitong said.

"Did the truck driver do it?" Xu Tian asked.

"It is basically certain that the police did not collect the DNA of the murderer and the truck driver during the investigation, and only investigated the DNA of three police officers." Li Zhitong said.

"Then it doesn't make sense, how did the truck driver escape with the murderer?" Xu Tian asked.

"At that time, there was a color steel house on the side of the road where the truck stopped, in fact, the color steel house was a cover, and it was a secret passage leading to a village not far away, and Lao Chen did not rush into the fire because he quickly discovered the secret road. Lao Chen fainted soon after going down to the secret passage, at that time the fleeing truck driver and the murderer had already fled, and some gas was poured into the secret passage, but fortunately, they were in too much hurry when they escaped, and did not completely pour the gas in the gas bag into the secret passage. Li Zhitong said.

"That truck driver is the man who is too old?" Xu Tian asked.

"Honestly...... We just regard the truck driver as the executive Tai Sui himself, because the truck driver is not very old, almost thirty years old at the time, which is completely in line with the age of the executive Tai Sui. However, when Lao Chen described the appearance of the truck driver, we also asked the painter to depict the face of the truck timing, and the portrait was also placed in the case file, but the person was never found. Li Zhitong said.

"And what happened to this case?" Xu Tian asked.

Because of these things, the case was not closed, and the detective in charge of investigating the case was also transferred to another case, and the self-blaming Lao Chen staked his career in this case, but no matter how the police investigated, they could not find the figure of the truck driver. Mr. Chen had been tracking down the truck driver, and of course, the village near that stretch of the road had become the focus of the investigation. Lao Chen suspected that someone must have picked up the truck driver to flee, and also investigated the village, but the results were not big. Li Zhitong said.

"This happened four years ago?" Xu Tian asked.

"At the end of 2012." Li Zhitong said.

"But Lao Chen still found clues later, right?" Xu Tian asked.

In 2013, Dr. Lin approached Mr. Chen because of the investigation of the school's incident, and at that time, Mr. Chen had preliminary doubts about the time of Dr. Lin's investigation, but Mr. Chen could not tell Dr. Lin about the case, so he pretended to cooperate with Dr. Lin reluctantly to investigate. In fact, Dr. Lin was aware of all the incidents that Dr. Lin investigated, but Lao Chen was investigating in secret. Dr. Lin did not investigate the truth of the school incident, but Lao Chen found a glimmer of life through this. At that time, the students in the entire dormitory building became the target of Lao Chen's investigation, so Lao Chen sent police officers to follow up and investigate every student in the dormitory building one by one. It wasn't until he found out that one of the female classmates had suspicious points that Lao Chen finally found a breakthrough, but the female classmate died soon after, the same female student who hanged herself next door to Hailan's house four years ago. The schoolgirl's father was very suspicious.,Not long after.,The hero of the school case.,The girl named Tian Tian also died.,The cause of death turned out to be self-hanging.。 There is a great similarity between the two cases, the judgment of the two cases at the beginning is that the deceased hanged himself, but when the police investigated in depth, they were able to find definite evidence that the deceased was killed, Lao Chen knew that these two cases had a lot to do with the previous cases, and after Lao Chen investigated that Dr. Lin was not suspected of murder, he pulled Dr. Lin to the side of the police, so Dr. Lin followed Lao Chen to solve several homicides four years ago. Li Zhitong said.

"I see, so until now, the truth of all the cases has not been solved, right? The murderers in the Yanbei area were rescued by the truck driver, and they never appeared again? Xu Tian asked.

"The murderers of the two girls' suicide cases four years ago pointed to their relatives, but the murderer of another case of girls who hanged themselves that year also pointed to an outsider, Kang Yuliang, who was standing here. Lao Chen linked these three cases together, and under Lao Chen's guarantee, the real culprits in the three cases have been in custody and have not been tried by the court, and two years have passed since then, when Lao Chen cleared the suspects in the three cases, the fourth case happened. Li Zhitong said.
