"Subjectively, there is no such thing as a perfect crime.

No matter how highly intelligent a person is, as long as he commits a crime, there will definitely be traces of the crime. As long as you have an objective behavior, you will definitely leave an objective trace, and it is subjectively impossible to commit a crime without a motive, the crime must be a conscious act, and the unconscious behavior is innocent, even if it is a random crime without a specific object, it also has its hatred or bloodthirsty purpose.

An alibi is also impossible, because at the most basic level, people have no skills, the time of your behavior is an objective fact, and the alibi is a proof of it, if it cannot be reflected truthfully, then the proof itself is a non-rigorous existence.

Your so-called perfect crime is probably that none of the above three is known or legally proven, and each can be covered up with specific conditions in a specific situation, but the act of concealment itself will produce its traces, its purpose and the time of its execution, and so on, if perfection means that it is impossible to detect and impossible to prove, then it does not exist, and who knows what the unexpected situations will be?

The perfect crime is just that you are fighting against the complete probability, and if you succeed in getting away with the crime, you are just fighting against the police and the prosecution! This is the end of this class, the question raised by the students is very in-depth, it is a great idea for us to study the criminals themselves, I hope you can discuss more, okay, the end of the class. ”

On the podium, a delicate woman in a small suit picked up the phone while packing up the handouts: "Uncle Sun, why are you free to call me?" ”

There was a huge silence on the other end of the phone, and the woman's face gradually became solemn, and after a long time, she slowly nodded and said, "Uncle Sun, I'll do my best." ”

At ten o'clock in the evening, the nightlife of Changnan City has just begun, with bright neon lights shining and the streets full of barbecue stands.

Calling three or five friends, ordering some barbecue, having some beer, bragging, and ripping the skin, it's just refreshing.

At the same time, on the streets, several police cars sped through the streets, and the sound of sirens was extremely remote.

In the car, Zhou Qing's brows were locked, staring at the bustling night scene outside, and his thoughts didn't know where he was flying.

Just as the meeting was taking place, someone reported the case.

"There has been a murder in the Starlight Hotel!"

As the best five-star hotel in Changnan City, whether it is health defense or others, Starlight Hotel is the top existence in the industry, not to mention, people who can live in Starlight Hotel, either rich or expensive, with bodyguards are not a few, under the double protection, there was even a murder, which is a bit unusual.

Zhou Qing's mood was extremely heavy, and he vaguely felt as if he had fallen into a quagmire, surrounded by darkness, unable to struggle.

When the criminal police team arrived at the Starlight Hotel, the entire street of the Starlight Hotel was crowded with people, pointing to the roof of the Starlight Hotel.

It took a lot of effort for Zhou Qing and the others to enter through the dense crowd, and their hearts almost fell to the bottom.

The last case of the shredded body in the secret room was exposed, which has caused great panic in the society, and this case, I am afraid that there is no need to break the news, and the people of the entire Changnan City know about it.

"This road will be blocked and the crowd will be evacuated immediately." Before he got out of the car, Zhou Qing began to issue orders with a walkie-talkie with a blushing face.

Without the slightest hesitation, after getting out of the car, Zhou Qing went straight to the top floor of the Starlight Hotel.

"According to eyewitnesses, he felt that it was raining, wiped it on his face, but found that he touched blood, looked up, and found that such a person was tied to the Century Clock, so he immediately called the police, and at the same time found more and more people, according to the population, the entire hotel was surrounded by water."

On the top floor, a man with a full body of ** was tied to the Century Clock, and as the clock swayed, Zhou Qing said coldly: "Stop the bell immediately and rescue the deceased." ”

With the cooperation of the hotel lobby manager, the Century Clock stopped, and everyone hurriedly carried the body of the deceased to the roof of the building.

Zhou Qing looked around the top floor, his expression became more and more solemn, and asked, "Is the identity of the deceased confirmed?" ”

"The deceased is Liu Changzong, the young east of Changhua Group, who only checked into the hotel this morning, as if he was preparing to hold a birthday pate

t，”

Zhou Qing nodded and came to the side of Xiao Li of the Technical Department.

"Captain, the deceased has been preliminarily judged to have drowned."

"Drowning? Wasn't it strangulation? Zhou Qing frowned slightly, pointed to a bloody strangulation mark on the deceased's neck and said.

Xiao Li shook his head and said: "The deceased has no obvious traces of reaction to being strangled to death, and it is inconsistent with the state of suffocation, it is not ruled out that it is a scar that was strangled after death, but the deceased has a lot of water squeezed out of his abdomen, of course, the specific cause of death will have to wait for the forensic doctor to do a further autopsy to determine." ”

Zhou Qing nodded and said, "Try to protect the scene as much as possible, extract fingerprints from the murder weapon, as well as the fingerprints and footprints at the scene, whether it is the doorknob or the Century Clock, don't let it go." ”

The scene began to get busy again, and at this time, Qian Hao came over: "Captain, the specific situation has been understood, but ......"

"If you have something to say, don't babble."

Li Hao smiled awkwardly: "Captain, this time, the death of the deceased is also very strange. ”

"Huh? How so? ”

According to the bodyguard of the deceased, the deceased came to the Starlight Hotel to hold a pate

T, the time started at nine o'clock in the evening, but at seven o'clock in the evening, the deceased came to the cinema on the seventeenth floor, and with the deceased were two bodyguards. This movie theater is only open to a few super VIPs, the deceased chartered the venue today, the deceased entered the movie theater alone, about two hours later, the bodyguard felt that something was wrong, so he broke into the movie theater, and this is only to find out that the deceased was missing. ”

Zhou Qing's brows locked, in the cinema...... Drowning? The death of the deceased is indeed somewhat incredible.

A few minutes later, accompanied by the lobby manager, Zhou Qing and Qian Hao came to the cinema on the seventeenth floor.

The low-key and luxurious cinema, the transparent illumination of the golden orange lights, the twelve excellent viewing positions, and the huge 3D display, are indeed the VIP treatment of noble luxury.

After looking around, Zhou Qing said, "Is there only one entrance to this movie theater?" ”

"Yes, there's only one entrance to the entire cinema."

Zhou Qing walked around the movie theater, thinking hard, how did the deceased drown in the movie theater? Is it a restroom? Zhou Qing and Qian Hao walked towards the bathroom.

The bathroom was cleaned up very cleanly, Zhou Qing frowned, and asked, "After the incident, did anyone enter the movie theater?" ”

The lobby manager hurriedly shook his head and said, "No." ”

Zhou Qingdao: "Immediately notify the people of the technical team to collect fingerprints, sensors, basins, toilets, and don't let go of any details." ”

"Yes, Captain." Qian Hao responded.

Exiting the room, Zhou Qing still frowned, in the bathroom, there was no trace of a fight, drowning in the movie theater, this is incredible in itself, the deceased is a living person, if you want to drown him hard, the deceased will not resist, how did the murderer quietly complete the crime without alerting the bodyguards outside the door?

The case has spawned countless mysteries, shrouding Zhou Qing in it......
