Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Sun Hu's forehead was covered with beads of sweat, and he kept repeating that he only pushed Li Jianshe and did not kill anyone. Judging from Sun Hu's reaction, he did not seem to be lying, but the complexity of the case was far beyond imagination.

Medical examiner Zhang Kai conducted another detailed examination of Li Jianshe's body and found that in addition to the impact injury consistent with Sun Hu's description, there was also a hidden scar inside his skull. This scar was located near the brain stem and was caused by a thin, sharp object. The wound also showed signs of infection, indicating that there was a certain interval between the time of injury and the time of Li Jianshe's death. This discovery made Lu Chuan realize that after Li Jianshe was pushed down and injured by Sun Hu, someone else had dealt him a fatal blow.

But who is this person? After Sun Hu came into contact with the deceased Li Jianshe, who else came after him and eventually took Li Jianshe's life?
Just when the investigation of the case was at a stalemate, the traffic police sent back information that they had investigated all vehicles that passed by 15 days ago on the road near the cave where the body was found, and found two suspicious light trucks that should match the tire marks found at the crime scene. After receiving this information, Lu Chuan immediately arranged for Wang Shuai to track the vehicle. After spending a day, they finally found the vehicle, but it had been burned beyond recognition and was in a ravine.

Wang Shuai stood in front of the scrapped light truck, frowning, feeling helpless and unwilling. The vehicle in front of him was only a charred shell, the tires had long melted, the windows were shattered and scattered all over the ground, the body was twisted and deformed, and it exuded a pungent smell of burning. He knew that the difficulty of obtaining clues increased suddenly after the vehicle was burned like this, but he had no intention of retreating.

"Captain Wang, what should we do? The car is burned like this, can we still find any useful clues?" The auxiliary police officer Xiao Li at the side frowned and asked with a worried look on his face.

Wang Shuai patted Xiao Li on the shoulder and said firmly: "Don't be discouraged. Especially at this time, we must not give up. Even if there is only a glimmer of hope, we must try our best."

Wang Shuai carefully walked around the vehicle, not missing any corner. He squatted down and carefully observed the chassis of the vehicle. He found that although a part of the chassis was also burnt, some signs of wear and tear could still be seen. "Xiao Li, quickly get the tools and cut off this chassis. Take it back and let the technical department study it carefully. Maybe we can find the model and source information of the vehicle." Wang Shuai said as he put on gloves and prepared to operate it himself.

Under Wang Shuai's command, the auxiliary police began to dismantle the vehicle and collect evidence in an orderly manner. They found some residual fabric fibers in the driver's seat of the vehicle, which looked to have a special texture. "These fibers may be left by the murderer. Collect them carefully and compare them with the fibers found at the crime scene before." Wang Shuai urged.

Meanwhile, Lu Chuan was also busy in the police station. He carefully studied the vehicle information provided by the traffic police and found that the two light trucks were fake license plate vehicles, and the vehicle registration information was also forged. "It seems that the murderer had prepared in advance and deliberately used fake license plate vehicles to commit the crime in order to evade investigation." Lu Chuan said to himself. But he was not intimidated by the difficulties, but became more determined to solve the case.

After several hours of hard work, Wang Shuai returned to the police station with the collected evidence. Colleagues from the technical department immediately conducted a detailed analysis and testing of the evidence. Lu Chuan, Wang Shuai, Zhang Hui and others sat in the conference room, anxiously waiting for the test results.

"Captain Lu, after analyzing the wear marks on the chassis, we preliminarily determined that this vehicle is a light truck of a certain brand produced three years ago, and the manufacturer is in a neighboring city. However, due to the fake license plate, the specific source of the vehicle needs further investigation." A colleague from the technical department reported.

"What about the fiber testing? Any findings?" Wang Shuai asked anxiously.

"The fiber test results show that the fibers found on the driver's seat of the vehicle and some of the fibers found at the crime scene are of the same material, and are likely left behind by the clothes the murderer wore when he committed the crime. However, this fiber is a common industrial fabric material, and it is difficult to trace its specific source on the market." A colleague from the technical department said regretfully. Although the clues are still limited, these findings still give everyone a glimmer of hope. After thinking for a moment, Lu Chuan said, "Since we know the manufacturer of the vehicle, we will start from there. Wang Shuai, you lead the team to the manufacturer in the neighboring city to investigate the sales records and flow of this car. Zhang Hui, you continue to investigate in this city to see if you can find other clues related to this car, such as vehicle maintenance records, refueling records, etc. In addition, strengthen the investigation of Li Jianshe's social relations, and perhaps some new suspects will be discovered."

"Understood!" Wang Shuai and Zhang Hui responded in unison, and then quickly took action according to Lu Chuan's instructions.

Although the car had been burned, the police still obtained some information about the car, such as the frame number. As long as they had the frame number, it would be relatively easy for the police to find information about the car.

Soon after investigation and comparison by the traffic police detachment, it was discovered that the owner of the car was a man named Zhao Baogang, who ran a used car repair shop.

Wang Shuai and others came to Zhao Baogang's scrap car repair shop. The smell of oil and rust filled the air. Various scrapped vehicles were parked in a mess, and workers were busy shuttling between them. Zhao Baogang, a burly middle-aged man with an oily face, frowned and looked helpless when he heard the police's intention.

"Comrade police officer, we have too many cars here, coming in and out every day, and I really don't pay much attention to which car is still there and which is gone. Everyone in this area knows that what I have here is a hodgepodge of old cars, and I really can't take care of them all." Zhao Baogang spread his hands and said with a bitter face.

Lu Chuan looked serious and looked at him sharply: "Zhao Baogang, this is no small matter. This car is related to a major case. Think about it carefully. Have there been any unusual circumstances or suspicious people recently?"

Zhao Baogang scratched his head and tried to recall: "There's really nothing special. There are too many people coming here every day to sell cars, buy cars, and look for parts. Oh, by the way, a while ago a man wearing a black hat and a mask came and asked if there were any cheap trucks, but I didn't pay much attention to it at the time."

Wang Shuai immediately asked, "How tall is this person? Can you remember any other characteristics?"

Zhao Baogang squinted his eyes and thought for a while: "As for his height, it seems to be around 1.75 meters. As for the rest... I really didn't pay attention. He covered himself tightly and spoke in a very low voice." (End of this chapter)
