Under such strong pressure from the organizers of the event, Ansheng and Fan Bu finally stopped talking about the dead, and everyone else also fell silent.
Even Zhang Li took his eyes back and waited for Mo Sheng to announce the rules of the game.
"The rules of the game are simple."
Mo Sheng quietly looked at the flames dancing in the brazier and the barbecue dripping grease on the brazier, and said calmly:
"I will tell the facts of a murder case that was a perfect crime. Whoever can first tell the method used by the criminal behind the scenes will win."
"The perfect crime?"
Boss Fan Bu is going to get into trouble again.
"Where can there be a perfect crime? According to Locard's law of material exchange, the criminal will always leave traces."
From a killing game master to an investigator at the problem center, although this guy relies on his mind-reading ability, his professional knowledge still makes up for it.
Unfortunately, Mo Sheng ignored him and started talking about her case seriously.
"In June 2021, Mo Sheng's family, including his parents, her grandparents, a total of five people, traveled here, which is Tiantong Mountain."
"Hey, you don't want to talk about the case of your... no, Mo Sheng... your death, right?"
Fan Bu was also shocked when she said this.
"Isn't your case already determined to be an accident?"
The current Mo Sheng's soul is actually Qi Mei, and the real Mo Sheng has died in an accident. Everyone at the center of the problem knows this.
But except for Fan Bu, no one had seriously looked at the case file of this accident. It was obviously an accident, so what's there to see?
The only one who has this patience is Fan Bu, who very, very seriously wants to be a real problem center investigator.
This guy, among other things, went through all the case files that were transferred to the problem center.
Mo Sheng's case was transferred not because of how difficult it was. But because Suzaku wanted to use this corpse, it was sent as a "background introduction" to the corpse.
"Yeah. It has to be a perfect crime to be classified as an accident."
Mo Sheng replied calmly.
"Then why do you think this was the perfect crime and not just an accident?"
Fan Bu asked.
Meng Fei also felt that something was wrong with this reasoning game.
The atmosphere didn't get any more lively. With the flickering of the firelight and the top of the half-can of beer, the dense and sticky darkness around him became even more dense.
"No, it's just a game.
"The rule of the game is, whoever explains how the murderer created such a perfect accident will win."
Mo Sheng put aside the facts and brought everyone back into the interesting game.
“Our family of five took our own luggage, had lunch at Tianmenyi, and then bought some things in the small supermarket.
"Then we boarded the sleep bus on the Tiantong Mountain line. The sleep bus at that time was the same as now.
"There are five rows of seats, which can seat up to twenty people. We were the first to get on the bus. After us, we waited for about a quarter of an hour, and two more families came.
"So in addition to our family of five, there were six people from another two families on the bus, adding up to a total of 12 people. Then the bus set off.
“An hour after setting off, the vehicle lost control and slid off the lake road into the water.
"It took another hour before the tourist area realized that a vehicle had lost contact and called the police. After that, the investigation officially began.
“Because the place where it fell into the water was not entirely certain, the police spent a long time searching, and it was only the next day that the vehicle was successfully fished out of the water.
"Our sleep bus fell into the lake about 40 meters deep. All the windows were crushed by the water pressure.
"Everyone died in the car, all were wearing seat belts, and no one broke out. All of them met the characteristics of drowning and suffocation.
"Almost everyone had injuries. The driver's head and face injuries were particularly serious.
"Investigators concluded that the cause of the injury was that when water pressure crushed the window, broken glass and water poured into the car, hitting the driver's head and face, causing injuries.
"Most of the other passengers suffered similar injuries to the driver. However, these injuries were not fatal.
“Autopsies of the deceased showed that these people had pulmonary edema caused by asphyxiation. Their lungs were filled with lake water and they all drowned.
"Investigation of the vehicle's EDR system revealed that the vehicle had been driving normally until the accident when it reached a bend on the lake.
“At that point, the driver released his foot on the accelerator, but instead of following the curve of the road or applying the brakes, he used his inertia to slide into the lake.
"The speed was not very fast at the time. The speed before the accident was 40 yards. If the driver paid attention to the road conditions and stepped on the brakes in time, nothing would have happened.
"No mechanical fault was noted with the vehicle. There was nothing unusual about the road itself.
“Therefore, the investigation concluded that the accident was caused by the driver’s inattention, and the case was closed.
"Who can think of a way to carry out this crime perfectly and get away with it without any suspicion?"
After Mo Sheng quietly explained the case, he still stared at the dancing fire in front of him, waiting for everyone's answers.
"If I were investigating this case and suspected a crime rather than an accident, my first suspicion would be the driver."
Ai Ting's crystal jewel-like eyes reflected the red light of the brazier.
"If the murderer is the driver, then this is suicide, not a perfect crime."
Meng Fei touched his wife's head and reminded her.
"Well, yes. But if I check, I will definitely check the driver first."
Although she knew that if the murderer was the driver, it would not comply with the "escape intact" rule, she still couldn't get rid of the inertia of being a criminal investigation captain for many years.
"Does the driver have any financial disputes? Medical records? Large life insurance? Or has he received a huge transfer?"
A tragic story about an old driver who was desperate for life and decided to make a last ditch effort to leave everything to his family came to her mind.
"Well, the criminal investigation at that time did investigate these."
Mo Sheng added more follow-up.
"They concluded that the driver himself was normal, had no financial disputes or financial abnormalities, and was in good health.
"Not only that, they also investigated everyone in the car. There should be no motive for any of them to die with everyone in the car.
"So the Criminal Investigation Bureau ruled out the possibility of criminal involvement and the case was transferred back to the Traffic Management Bureau."
Of course motives are just motives. The real motive may be very secret, and the Bureau of Criminal Investigation may not be able to investigate it.
And even if there is no motive, it does not rule out that someone suddenly has a psychotic attack and decides to drag many people to their death.
Meng Fei still remembers seeing a bus falling off a bridge on the news in his previous life, killing more than forty people.
The cause of the accident can be seen clearly from the surveillance video in the car. It was caused by a quarrel between a passenger and the driver and grabbing the steering wheel.
"Now that the data from the EDR system has been extracted, what about the in-car video records recorded by the cameras in the car?"
he asked.
EDR systems are similar to the black boxes on airplanes. It records various data on vehicle driving and control, and does not include video inside the car.
But in order to reduce the possibility of disputes in tourist buses like sleep buses, there must be cameras in the car.
"Excuse me."
Mo Sheng announced the unfavorable result in her usual ominous tone.
"Due to the water short-circuit, the surveillance equipment was destroyed and the surveillance video can no longer be extracted."
