Looking at the old man who was lying in a pool of blood at the moment, the crowd at the banquet scene began to stir, and Gao Yuan, who was guarding the door and not letting people leave, felt a little powerless at first in the face of a group of guests who planned to leave the scene.

Fortunately, there were not too many people in the banquet hall, and there was a police department called Nakamori Ginzo to maintain the scene, and soon, the order of the scene was controlled.

After receiving the alarm, Officer Twilight immediately led the team to the scene, so the order of the scene was taken over by the criminal police of the Metropolitan Police Department.

"The deceased's name is Hisaku Ohashi, and he is the president of the Ohashi Foundation, and judging from the situation at the scene, it should have been caused by a shooting."

After a brief questioning, Officer Takagi began to report the case to Officer Twilight.

"According to the testimonies of the guests at the scene, today the deceased was preparing to hold a charity auction in this villa. At the beginning of the auction, the deceased asked the attendants at the venue to turn off all the lights in the banquet hall, and then in this completely dimly lit banquet hall, a gunshot rang out, and when the lights were turned on again, the deceased had already been shot and died. ”

"In other words, someone shot President Ohashi while the lights were out?"

Officer Twilight concluded, "So, has the murder weapon been found?" ”

"Found it."

"After the gunshot, the window of the banquet hall was broken from the inside, and after searching the lawn outside the window, a pistol and a night vision goggles were found. ”

"Pistols and night vision goggles? In other words, the murderer chose to throw the murder weapon out of the window directly? ”

Officer Twilight said.

"Well, that's how it should be."

Wataru Takagi said.

"So if that looks like that......"

"The murderer should still be at the banquet."

Interrupting Officer Twilight's words, Gao Yuan couldn't help but step forward and say.

"Oh! Wise brother! You're here too! ”

Seeing Gao Yuan, Officer Twilight said with some surprise.

"Yes, Officer Twilight."

"When the gunshots rang out, I stood at the door and was sure that no one had left the scene after the incident. ”

"That's easy!"

Hearing this, Officer Twilight said happily, "Just check whether everyone present has a gunpowder reaction, and you can know who fired the gun!" ”

As a result, Officer Twilight instructed the officers to prepare to test everyone present for a smoke reaction.

"Thanks to you, wise brother, it seems that this case will be solved soon."

Officer Twilight laughed.

"Where, the main thing is that Officer Nakamori is at the scene to maintain order, otherwise I wouldn't be able to stabilize so many guests."

Gao Yuan said.

Next, everyone is waiting for the police to start testing for the smoke reaction. And taking advantage of this opportunity, Black Feather Kuaito quietly walked behind Gao Yuan, turned his back, and said to Gao Yuan in a very small voice:

"Mr. Wise, it seems that today's trip is in vain."

"There's no way to find out where that diamond came from?"

In this regard, Gao Yuan did not look back, and couldn't help but ask in a low voice.

"That diamond is said to be in the personal collection of Chairman Ohashi, only Chairman Ohashi knows its origin, and now that the person is dead, I'm afraid there is no way to know the details."

After the black feather fights back, he leaves without incident.

In this regard, Gao Yuan did not feel much helpless, after all, there was no need to investigate this matter for himself.

Soon, the results of the gunsmoke reaction test for everyone were available - at the scene, there were two people who were detected with gunsmoke reactions, namely the girl and the middle-aged man who were standing next to Hisaku Ohashi at that time.

"In other words, the murderer is among the two of you!"

With the results of the examination, Officer Twilight looked at the two of them with serious eyes.

"Hey! Are you kidding! How could I have killed my grandfather! ”

The girl couldn't help but say angrily in the face of Officer Twilight's questioning.

"Wronged, officer! I was only invited by Chairman Ohashi to preside over the auction, so there's really no reason to kill Chairman Ohashi! ”

The middle-aged man said with a little panic.

"However, judging by the results of the smoke reaction......"

"It's unlikely they're the murderers."

Officer Twilight, who was looking at the two of them with serious eyes, was suddenly interrupted by Takato, which made Officer Twilight a little out of shape, and couldn't help asking:

"Wise brother, why do you say that they are unlikely to be murderers, but the gunpowder reaction is only found in the two of them! How do you explain this? ”

"Just because they both have gunsmoke reactions, it's unlikely that they are the murderers."

Takato explained.

"Before the lights went out, the two of them stood beside the deceased. When the lights came back on, the position they were standing in didn't change. Therefore, the two of them had a gunsmoke reaction, which can only indicate that the murderer fired the gun very close to them at that time, that is, the murderer fired the gun while standing next to the deceased. If you don't believe me, you can test the deceased, and the deceased should also have a gunpowder reaction. ”

"But, if you say that, aren't they even more suspicious!"

Officer Twilight wondered, "Just because the murderer fired the gun next to the deceased, then the suspicion of these two people standing next to the deceased is not the biggest!" ”

"Because of the location of the window."

Faced with Officer Twilight's doubts, Gao Yuan felt a little helpless and said, "The broken window is located at the entrance of the banquet hall, and the position where the deceased is standing is in the innermost part of the banquet hall, and the distance between them is nearly thirty meters. ”

"What's going on?"

Officer Twilight was still puzzled.

"The window was broken from inside the house, and the murder weapon was found in the lawn directly opposite the window. In other words, after committing the murder, the murderer walked to this window, broke the window, and threw the murder weapon down. ”

Gao Yuan said, "According to the gunsmoke reaction, the murderer fired the gun next to the deceased, which means that after the murderer committed the murder, he ran from the innermost part of the banquet hall where the deceased was located, ran to the window at the entrance of the banquet hall, and threw the murder weapon out." At that time, there was no light in the banquet hall, and the distance was nearly 30 meters, even if the murderer could rely on night vision goggles to run from the deceased to the window, how could the murderer run back after throwing the night vision goggles out of the window? ”

Speaking of which, Officer Twilight finally understood what Takato meant.

"What's more, after hearing the sound of the window being broken, the service staff immediately turned on the lights in the banquet hall, which means that after the murderer threw the murder weapon out of the window, he didn't have much time to move around the banquet hall."

Gao Yuan said, "In other words, the murderer should have been standing among the guests near the window after the lights were on. And these two who have been standing by the side of the deceased cannot be murderers! ”

"That's it! How could we be murderers! ”

Hearing Gao Yuan's words, the girl couldn't help but say, and the middle-aged man couldn't help but breathe a sigh of relief.

"I see! It's you, wise brother! ”

After listening to Takato's reasoning, Officer Twilight praised him sincerely, then changed the topic and asked, "So, who were standing near the window at that time?" You were at the entrance, you should have seen it! ”

"I don't remember!"

With a helpless smile, Gao Yuan said.
