The scene of the accident shows that the back half of the Mazda body almost disintegrated. The perpetrator suffered from "acute transient mental disorder" at the time of the crime? On the evening of September 5, 2015, the Qinhuai District Procuratorate responded to questions from all walks of life by saying that when the hospital reviewed the evidence materials, it found that there was evidence that Wang Jijin had mental abnormalities before and after the crime: First, the police information and 110 police call recordings confirmed that about 2 hours before the accident, Wang Jijin had called 110 to call the police, saying that someone had harmed him, his mobile phone had been monitored, and he could not answer whether what he had done was right or wrong; second, Wang Jijin's relatives testified that Wang Jijin had been followed the day before the crime, and others knew his whereabouts.

The two forensic medical appraisals of the defendant should be considered that he was in a mental state at the time of the crime, and the prosecutor, the defense, and the victim all agreed with the appraisal conclusion in court. Defendant Wang Jijin. Why did the perpetrator run a red light at high speed? Was it involved in drunk driving or drug driving? Some citizens said that in the BMW car that caused the accident, a package of powdered items Some netizens speculated based on his performance at the police station that the driver was unable to control the vehicle after taking drugs, which eventually led to the tragedy? There were online reports that the perpetrator was suspected of having a drug addiction and hit his head against the wall at the police station. The police had to wear a helmet for him. This statement has not been confirmed by the police. Wang Jijin was later taken to the hospital by the police for a urine test, and no alcohol was found in his body, ruling out the possibility of drunk driving. The police found a package of suspicious white powder at the scene of the accident. The package of white powder was suspected to be from a BMW. According to the test of the Institute of Science and Technology of the Nanjing Municipal Public Security Bureau, no common drug ingredients were found in the white powder, and the name of drug driving was lifted. The scene was terrible. Is the perpetrator the second generation of rich and official as rumored on the Internet? After investigation, the alleged offender Wang Jijin (male, 35 years old, from Jingjiang, Jiangsu), temporarily lives in Jiangning District, Nanjing, and his parents are currently farming in his hometown in Jingjiang. His father worked in Nanjing in 1992, and then ran a water and electricity material sales business in a decoration city. In 2006, due to physical reasons, he handed over the store to his son Wang Jijin. His mother has no job. According to Wang Jijin's family, Wang Jijin from Jingjiang is not a post-90s generation. He has been in Nanjing for almost 20 years. He has been doing hardware and building materials business in a decoration city in Nanjing. "Although he has been doing business for more than ten years, to be honest, he has not made much money. Although he drove a BMW, we have told him many times that he must keep a low profile." Wang Jijin's cousin said. After investigation, Wang Jijin's quasi-driving model is A2 photo, the valid start and end date of the driver's license is March 16, 2011 to March 16, 2021, and the valid period is 10 years. After investigation, the registered owner of Shaanxi AH8N88 BMW is Xu Moumou, and the actual user is Wang Jijin. After investigation, the owner of the car changed hands many times due to debt disputes. Wang Jijin bought and used it privately at the price of 400,000 yuan in early 2015, but did not go through the relevant transfer procedures. Two young people on the Mazda car were thrown out of the car and died on the spot. How fast did you drive? On June 29, 2015, the Nanjing traffic police announced the speed of the "6.20" BMW accident. After identification, the speed of the BMW was as high as 195.2 kilometers per hour. What is the concept of 195.2 kilometers per hour? This speed has reached the speed of ordinary high-speed trains. The speed of 195.2 kilometers per hour is 54.2 meters per second. The weight of the BMW plus the fuel and the weight of the driver is about 2000 kilograms. If calculated at a speed of 54.2 meters per second, the kinetic energy of the BMW when it hits the Mazda is 2937,640 joules (that is, about 2.94 trillion joules), which is equivalent to the energy generated by lifting a 294-kilogram iron block to a height of 1,000 meters and falling to the ground. To put it more intuitively, according to public information, the muzzle kinetic energy of the AK47 assault rifle is 1989 joules, so the kinetic energy of the BMW accident is equivalent to the energy of 1476 AK assault rifles firing at one point. For example, the RPG rocket launcher, which is often used to attack US armored vehicles in Iraq and other places, has a mass of 2.3 kilograms and an initial speed of 950 meters per second, which is only 1.04 trillion joules. Why was the Nanjing BMW case fired when the Nanjing auxiliary police uploaded the scene video of the BMW accident? Shortly after the incident, a small video of about 5 seconds spread rapidly on the Internet. In the picture, the Mazda seemed to be hit by a cannonball and flew over wrapped in smoke. This video comes from the surveillance above the intersection of Shiyang Road and Friendship River Road. It was this video that exacerbated the spread of the incident. After the video circulated, the relevant leaders were very angry and wanted to find out who had spread the video. Soon the answer came out. It was an auxiliary police officer in the command room (really a temporary worker). He was fired immediately. The picture shows the BMW involved.
