Masaji Zhang's body hung in front of the screening port, and the rope that lifted him was tied to a beam more than two meters high above the screening port. Beside Zhang Tian Zhengji, a herringbone ladder stood quietly.

"Oh... Chiba said that this way of dying was really impressive. "Oh my God..."

"Ah!!h Ayumi's screams immediately rang out and resounded throughout the screening room.

"Police!" As soon as Ayumi's screams rang out, Officer Twilight's shouts appeared at the entrance of the screening room.

Was it the text message from before? . .

。。。

"The deceased's name is Masaji Zhangda, 43 years old," the forensic officer reads the report. "I am the owner of the real estate agency 'Zhangtian Real Estate' in the neighborhood. At the same time, the movie theater, which is going to close today, has also been bought by him. ”

"Does this Mr. Masaji Akida come here often?" Officer Twilight asked the staff at the movie theater—the sister at the front desk, the muscular man, and the director.

"He's been here a lot lately," the dean replied. "I should have come to inspect the progress of the demolition team."

"Although he famously came to check on the progress of the work," the front desk service sister complained. "But he's always here to make trouble and cause a lot of trouble for us!"

"The reason why we have less traffic here is also because this guy interferes with the operation activities here every day!" The burly man said fiercely. "Fight with the thugs in the movie theater, gather the thugs in front of the movie theater, and write extremely obscene slogans near the movie theater. If he hadn't made trouble every day, the dean wouldn't have been forced to sell this place to him! For example, he has been smoking in this forbidden movie theater today, and even smoking under the screening opening, causing the movie to appear unexpected. ”

"According to the testimony of an aunt who has been chatting with the neighbors here," the forensic officer continued. "From six o'clock in the evening until now, no one has been in or out of the cinema."

"Six o'clock?" Officer Twilight glanced at the paper report. "In other words, if this is a homicide case, the people suspected of murder are the four adults present!"

The young man, the burly man, the front desk service sister, and the old cinema director who had previously dissuaded Yuan Tai from making noise.

。。。

As Conan and Twilight listen to their confessions, Chiba begins to observe the scene.

If it's suicide ...

Zhang Tian Zhengji came to the ladder that had been prepared in advance, and glanced at the rope loop placed on the top platform of the herringbone ladder. After picking up the rope loop and putting it around his neck, he kicked his feet and left the ladder, and the whole person was hung by the rope and shook in mid-air.

This is not true.

First of all, the model of Zhang Tian Zhengji's hanging can be regarded as a pendulum model if it is physicalized. If it was really Zhang Tian Zhengji who jumped over by himself, in terms of the relative position of the herringbone ladder and the rope loop, the pendulum starting point of this pendulum model would be very high, and it should be able to carry out a large-angle pendulum movement at a very fast speed.

However, when Zhang Tian Zhengji's body first appeared at the screening entrance, it was swinging at a relatively slow speed, and the swing was not large...

Secondly, even if you hang yourself, you can kill people very slowly. If it is really Zhang Tian Zhengci who committed suicide, then when the lights are on, Zhang Tian Zhengji will not be able to die at all, and there will definitely be no less subconscious struggle or something.

But Zhang Tian Zhengji was obviously dead at that time, and he didn't move at all.

In addition to this, Masaji Zhang Tian himself did not

In other words, the suicide theory of Zhang Tian Masaji can hardly be justified.

If he kills ...

After someone strangled Zhang Tian Masaji, he hung Zhang Tian Masaji there.

But if that's the case, there's a question that can't be avoided.

The corpse was hung directly from the screening port, and the time difference between the appearance of the corpse and the turn on of the lights was a maximum of 3 seconds.

Chiba walked down the aisle behind the last row of the screening room where Masaji Zhangda's body was located, and tried to run.

Even a weight of 20 kilograms makes an innegligible sound on the wooden floor when running at full speed.

Even if a normal person acts in a race walk, it is difficult to run 10 meters in 3 seconds, and if you row ten meters from the place where Zhang Tian Zhengji ———— when the lights are on, there is no one within 10 meters of Zhang Tian Zhengji...

How is this done? Whether it is suicide or homicide, there are natural problems with implementation...

If you think about it from the other side————

There is no mechanism here that can save effort to hang Zhang Tian Zhengji, so the murderer needs to use physical strength to hang Zhang Tian Zhengji... Whoever can do this ...

The sturdy man should be without pressure, and the strength of the dean and the service lady may not be enough, and the strength of the youth may barely be able to do it—but if it is said that he has to step on the herringbone ladder and then hang Zhang Tian Zhengji, the young man alone is also powerless.

So, the only one who can do this is that sturdy man, right?

But,That guy seems to be the one who showed the videotape... He should have been in a movie room across the wall when the body was hoisted... Could it be that there is some mechanism? There are four windows on the other side of the screening room, and all of them have glass, if the glass of one of the windows can actually be opened...

Qian Yu thought as she walked in through the door that led to the projection room not far away.

The screening room was cluttered – probably with the thought that today would be the last day and that it would never exist again.

Two projectors stand silently in the projection room, one of which is turned off while the other is on standby.

The four windows of the projection room are parallelogram layouts with two high and two low, the two lower ones are the projection ports of the projector, and the two higher ones are probably the viewing windows of the projectionists!!???.

After Qian Yu looked out of the viewing window, he found something terrible, and hurriedly left the screening room, returned to the movie hall, and walked to the last row of seats.

Mr. Masaji Zhangda, a smoker, had been smoking cigarettes until he died, and the cigarette butts and ashes fell to the ground. But judging from the position of the cigarette butt and ash, Zhang Tian Masaji probably dusted the cigarette ash under his feet and threw the cigarette butt to the right hand.

If I'm not mistaken, Masaji Zhang Tian was sitting directly below the screening port, but...

The cigarette butt is not located below the projector that is turned on, but under the viewing window corresponding to that projector!

Did you use any mechanism to seal the projector's normal projection port and then project the image from the viewing window?

Well, the sturdy videotape projectionist must have been involved in the case – otherwise he would have easily discovered that it was not the projection port, but the viewing window.
