Chapter 3292 3304 [Case Closed]
After a brief moment of surprise, as a quick-witted detective, Conan understood what he should do the next moment.
With great speed, he put on the noise-isolating earmuffs. At the same time, he closed his eyes and turned around swiftly, facing the quiet corner where no one was.
Next to him, Haibara Ai was startled by his sudden movement, and then looked at the thing on his ear with her eyes twitching slightly.
She knew the role of noise-isolating earmuffs: when Conan was throwing a tantrum at Professor Agasa's house and asked the professor to make him a small noise-isolating prop that could block Jiang Xia's reasoning, she was drinking tea silently beside him.
And now... I didn't expect that the doctor actually did it, and Conan actually kept this thing with him and actually put it to use.
Just as he was thinking in silence, at this moment, Conan's second countermeasure besides wearing earmuffs also showed its intended effect.
With Jiang Xia's casual gesture, countless eyes followed his finger and turned to one of the staff members.
And in the center of everyone's sight, the man with the middle-parted hair had a changed expression.
He was stunned and horrified at first, then took a deep breath and tried to put on a natural sneer: "Mr. Jiang Xia, are you kidding? Isn't the situation in the video very clear? Before and after the incident, the living room was very quiet, and there was no sound of the murderer coming or running away.
"I don't have night vision, so I can't move silently in the darkness. In fact, you know in your heart that the only person who can kill Gucun is Suidao who is catching up on sleep with him in the living room! - You can't let him off the hook and frame him just because he is your fan!"
As a technician who had little contact with the outside world, Zhongbiantou racked his brains and came up with all his words of speech.
After saying this, he let out a breath and waited for everyone to cast their suspicious eyes towards Jiang Xia.
However, when he looked around quietly, the scene he imagined did not happen. Instead, Inspector Megure said dissatisfiedly: "Brother Jiang Xia is not that kind of person. You, even now, still don't honestly explain the problem."
Although the other police officers did not speak, they nodded in agreement after their superior spoke: That's right, they have already been caught by Mr. Jiang Xia, why are they still resisting? - There is no point at all except making them work more overtime!
Middle-parted hair: "..."
In the end, it seemed that Jiang Xia was the only one who listened to him seriously.
After patiently waiting for him to finish speaking, the detective calmly answered his question: "It was because it was too quiet that it seemed abnormal - the deceased had clearly turned off the camera after filming the video diary, but when the murder happened, it suddenly started working again..."
"If the murderer really touched it when arguing with the deceased, then it would definitely record the corresponding movement after it was turned on. But in fact, there was nothing at all."
"That is to say, the camera was not turned on by 'accident', but the murderer walked through the darkness to the sofa and deliberately turned it on before starting to kill."
Jiang Xia looked at the technician whose face changed slightly: "In other words, the murderer was very sure that he could leave the scene in the dark without making any noise after killing someone, so as to pin the crime on Mr. Hosima. Speaking of which, the term 'operating in the dark' is actually very suitable for your work as an imaging technician."
“Your usual job is to check whether the film negatives are damaged in the darkroom.
"This job has very high requirements for the environment. In order not to damage the film, it must be carried out in darkness. But having said that, if there is absolutely no light at all, it will be difficult for the staff to confirm their position, and they may even accidentally trip over other objects and bump into important instruments.
“So in the darkroom, we actually use a very weak light source to mark the location of important items.
"You thought of this, so you found coordinates in this room that could be used for positioning, and pasted a piece of inconspicuous fluorescent tape on them as a mark."
“Like here.”
Jiang Xia stopped beside the desk and pointed to a two-centimeter-long piece of black tape on the edge of the table.
Haibara Ai happened to be right next to them. She turned her head curiously and looked, then found a faint light-colored edge under the black tape.
She understood immediately - someone had put a small piece of fluorescent tape on the edge of the table and then covered it with black tape.
As Jiang Xia spoke, he turned off the light and the room suddenly became dark.
In the darkness, the voice of the famous detective rang out: "If you just use fluorescent tape, then once the lights are turned off, that relatively bright light source will be quickly discovered by others."
“In order to avoid this, Mr. Genshan combined his usual work experience and covered the fluorescent tape with black tape of the same size.
"Then the tape will be so dim that it won't be immediately visible to the human eye even when the lights are turned off."
"After your eyes have completely adapted to the darkness and become extremely sensitive to light..."
As they were talking, as expected, as they stood in the darkness for a while, a few inconspicuous points of light gradually appeared from nothing into their field of vision.
Jiang Xia turned on the light again: "With these light spots and the memory of the environment in the room, as long as you practice a few times, it will not be difficult for a professional like Mr. Genshan to avoid all obstacles, walk to the sofa, and then leave quietly in the same way."
At this time, the young police officer from the forensic department discovered something. He looked at the camera that Jiang Xia had just handed back to him and said in surprise: "There is also a piece of tape like that on it!"
Jiang Xia nodded. "It's rare to practice moving silently in the dark. Mr. Genshan probably felt that relying on the witness's description alone was not safe, so he turned on the camera to record a sufficiently accurate 'alibi' for himself."
The man had a middle-parted hairstyle and a pale face.
At this time, Officer Gao Mu thought of something and hesitated, "But the deceased's sleeping position should be random - how did Mr. Genshan accurately stab him in the heart in such a dark place?"
Jiang Xia: "You should remember that there was a button missing from the deceased's shirt."
"..." Officer Gao Mu had really forgotten about this matter. When Jiang Xia mentioned it, he remembered it again, "Yes, the third one from the top should have been torn off when he was fighting with the murderer."
Jiang Xia shook his head: "There was no struggle at all. The murderer walked up to the sleeping victim in the dark and killed him with one blow. After that, he pulled the button away with force."
