Of all types of crime, random crime is the most difficult to detect.
Because random cases leave very few clues, which are different from carefully planned cases. On the surface, carefully planned cases leave no useful clues, but in fact the more you do, the more mistakes you make. .
In order to eliminate traces of his existence, the murderer must do something outside of the crime itself.
These behaviors are actually more likely to leave clues for the police to investigate when solving a case.
More than ten years ago, there was a series of vicious robbery and murder cases in Haizhou City.
There is no pattern to the suspects' robberies and killings. They target different people, the amount of robbery is different, and the crime locations are also different.
The police investigated the suspect's time and space for intertwined clues, but found no pattern, and finally concluded that the other party committed the crime randomly.
At two of the crime scenes, the other party's face was even photographed through surveillance, but the suspect was not caught.
The reason is that the other party commits crimes very randomly. After committing the crime, he immediately flees the scene and cannot hide until the next time he commits a crime.
After committing the crime, he left without using any means of transportation. He just escaped with his legs.
Moreover, he only went into an alley with no surveillance and relatively few people. He could not find the suspect at all with the help of two relatively blurry photos in the vast sea of people.
Later, after the other party robbed about a dozen people, he may have suddenly stopped because he thought he had enough money, and never committed another crime.
Until now, this case remains unsolved and has not been solved.
On the other hand, if you look at some plots to kill people, they think that they plan a seamless murder case, and there are few cases that go undetected.
The same goes for this case.
The other party thought that by crushing the car into pieces before the police arrived, all evidence would be eliminated.
In fact, it was the other party who scrapped the car and crushed it before the police arrived, leaving clues to his crime.
If Lu Chuan and Zhang Hui came to the parking lot at first, just to check the vehicles and suspect that someone deliberately caused a car accident, then the two of them have now confirmed this guess, that someone must have deliberately caused a car accident.
“Where’s the operator of the extrusion machine?”
“Yes, I’ll call over right now.”
"No, let's go there."
Scrap vehicle parking area.
Lu Chuan and Zhang Hui met the operator operating the extrusion machine that processes scrapped vehicles.
There is a complete process for scrapping vehicles. Public scrapped vehicles need to be recycled and evaluated by scrapped vehicle recycling companies.
You have to go through a series of procedures before you can enter a scrapped vehicle recycling company. The subsequent process is the same as that of a private scrapped vehicle.
In most cases, scrapped vehicles are extruded into scrap metal and sold by the ton.
But in fact, vehicles, especially some luxury vehicles, will be dismantled before being scrapped.
Of course, in theory, parts of such scrapped vehicles cannot be circulated into the market.
But... theory is theory, reality is reality, and there is always an insurmountable gap between theory and practice.
From a safety perspective, some scrapped vehicles are not due to their age. For example, vehicles that are total losses due to car accidents also need to be scrapped, and many parts of these vehicles may be new. It still has recycling value.
But no matter what the situation is, the police car that was involved in a car accident should not be pulled by a tow truck and then crushed into a pile of scrap metal.
“Why didn’t you follow the procedures for the police car you squeezed in the morning?”
The operator hesitated: “He...gave me a cigarette...and said it was a traffic drill. It's a scrapped car... I was asked to jump in line... and it was crowded..."
"You idiot! That's a police car..."
The person in charge of the parking lot He was so angry that he wished he could scratch his brother-in-law alive. This kind of place is only responsible for managing vehicles. It is a parking lot of the traffic police detachment. Naturally, it is impossible for there to be official police officers holding back here.
This kind of work was outsourced ten years ago. It cannot be said that the staff there have nothing to do with the police, but they are certainly not police officers.
"Forget it," Zhang Hui waved his hand and walked to the operator: "The man who gave you cigarettes, you should still remember his appearance, right?"
"He...he I was wearing a mask and a peaked cap...I didn't see clearly..."
"Damn it! You want someone to smoke!"
The person in charge now has the urge to hit someone.
"Are there any special characteristics that you can remember?"
"Characteristics...his eyes are not big and his speech is a bit hoarse...does this count...oh By the way, he smells fishy, very strong!”
He has small eyes, a hoarse voice, and a fishy smell.
This can be considered a feature.
Lu Chuan walked to the police car that had been crushed into a pile of scrap metal: "We still have to dismantle this and take a look. Maybe we can find something."
"Also, Brother Hui, can the tow truck driven by the other party be found? Source? "
"This is not a big problem. Tow trucks are different from ordinary vehicles. You must have corresponding qualifications to engage in the tow truck business. They are special vehicles. "
Zhang Hui looked at the parking lot and was responsible. Person: "The trailer driven by the other party can enter your parking lot. It should have been reported. Bring it over and have a look."
"Okay, okay, bring it over right away."
"That operator, bring the forklift over and see if you can get rid of this pile of scrap metal."
"Okay, come right away!"
The squeeze of scrapped vehicles is not through What large machine squeezes it into an iron block, but flattens it from top to bottom.
To put it simply, it changes from a three-dimensional car to a flat piece of scrap metal.
“Turn this over.”
What Lu Chuan wanted to see was the vehicle chassis. If the other party did anything to the vehicle, the best places to start would be the tires and brake pipes.
Boom!
The vehicle rolled, and the smoke and dust smeared Lu Chuan's face.
After touching it casually, Lu Chuan started to inspect the four tires.
Before a normal scrapped vehicle is extruded and scrapped, if the tires are still valuable, the tires of the vehicle must be removed.
This car obviously doesn't have it. The trailer was towed and squeezed directly, so the tires are still there.
All four tires had been squeezed and burst. Lu Chuan focused on observing the scars of the burst tires.
If the suspect tampered with the tires, he would most likely destroy them by scratching them.
Of course, this kind of scratch cannot be destroyed immediately, otherwise the police car will not be able to drive away, and Ren Qiang will also be able to find it.
It should be a deep scratch, but not to the extent of causing a break.
In this case, there will be traces of sharp cuts on the tires.
Lu Chuan is now carefully comparing the tire marks on each tire, looking for any cuts caused by sharp objects.
However, the results were far from ideal. (End of this chapter)
