For them who are looking for clues like "looking for a needle in a haystack", visual intelligence can only collect detailed information in one direction at most, but sound can collect all-round intelligence.
This is undoubtedly an important clue.
"Thanks for your hard work."
While waiting, Tang Ze looked at the busy crowd and couldn't help but take out his wallet and handed a few bills to Naoki Kamii: "Please go buy some drinks."
"Okay, no problem." Naoki Kamii took the money and started running errands, while Karasawa and Uncle Tomi started chatting.
"Although I appreciate the drinks, I'd rather we get more staff soon."
Uncle Dengmi looked at his busy subordinates and sighed helplessly: "With so few of us, we are busy all day long. The workload is really too heavy.
All the analyses are piled up in the Forensic Science Department, which could have been more meticulously categorized. Now, they're being forced to become jacks of all trades, juggling multiple roles."
“It’s really hard work.”
In the short time that has passed, two or three groups of criminals have come to submit evidence or obtain forensic reports. Tang Ze also feels that the forensic department is really working under load.
"Didn't you report the situation in the Forensic Science Department to your superiors and ask them to recruit more staff?"
Tang Ze suggested: "After all, you are our logistical support. Without you, the efficiency of handling the case will be greatly reduced."
This is not an exaggeration at all. After all, although it seems that forensic personnel in film and television dramas are just supporting roles, in fact, forensic personnel are indispensable for the efforts behind the scenes in many cases.
Regarding Tang Ze's suggestion, Uncle Deng Mi also revealed an internal information to Tang Ze that has not yet been made public.
That is, the forensic department is likely to undergo major changes in the near future.
"It seems that Uncle Tomi is also busy."
After hearing the news, Tang Ze couldn't help but jokingly said, "You've accomplished such a big thing without realizing it. You've really promoted institutional reform."
"That's not so exaggerated." Deng Mi waved his hands helplessly and complained: "This is all forced by this office worker-like job.
If I don’t speak up for my people, I’ll soon be out of people.”
"Is it so exaggerated?"
Naoki Kamii, who came back with drinks, heard the conversation between the two and couldn't help but interrupt.
“That’s just an exaggeration.”
After picking out a can of coffee from the bag, Uncle Dengmi opened it, took a sip, and said with a smile, "But after I reported this matter, the higher-ups also took it very seriously, and they quickly reached a consensus.
The proposal to reform and expand enrollment has been put on the agenda, and a conclusion may be reached soon.”
At this point, Uncle Dengmi also revealed a relaxed smile: "I hope it will be easier by then."
"Oh? That's good news." Tang Ze said jokingly, "But you may not be able to relax at that time.
At least in the beginning, you will be needed to guide the newcomers to adapt to this job."
"Those are just small matters. They will all be my helpers when the time comes." Dengmi said this and waved his hand nonchalantly.
After Karasawa finished choosing the drinks, Naoki Kamii also distributed the drinks he bought one by one.
As time passed, the audio from the two tapes began to be extracted one by one.
After hearing the news of completion, Karasawa and Naoki Kamii followed the instructions of the forensic personnel and went to a computer, put on headphones, and began to listen carefully to the movements in the video.
After figuring this out, Naoki Kamii began to listen attentively to all the sounds in the video.
Various conversations and laughter kept passing by his ears, but Tang Ze ignored them one by one.
"goodbye..."
Suddenly, a slightly deep female voice sounded, and the tone was different from those heard before.
Compared to the ease in the previous conversation, this "goodbye" seemed a bit sad and relieved. It was a very complicated feeling, like saying goodbye to the other person again.
After this sentence, there was the sound of clogs tapping on the stairs. It sounded like the owner of the voice said goodbye to the other person, turned around and left, and continued to move forward.
"Senior, this voice..." Naoki Kamii looked at Tang Ze in some surprise and doubt when he heard it.
"It sounds like that should be Hanako Imamura's voice." Tang Ze smiled and signaled Naoki Kamii to be quiet, then continued listening.
After the farewells, the crowd seemed to have gradually moved away, and the voices of conversation became increasingly distant.
Just when the two thought the sound was about to end, suddenly a soft bell sound came from the camera.
Then, a slightly hoarse female voice suddenly sounded.
"goodbye..."
Compared to the previous goodbye, this one makes people's hair stand on end.
Although there was no basis for it, Tang Ze and the other man both sensed murderous intent from the word "goodbye".
And after that, there was a sound of something heavy hitting the ground.
Although the recorded sound was very small, probably because the owner of the camera was moving upwards, Tang Ze was still able to quickly feel the muffled sound, which was caused by the deceased being pushed down the stairs.
"Senior, this..."
After hearing this, Naoki Kamii immediately took off his headphones and said in disbelief: "Could this be the sound of someone killing someone..."
"That should be correct." Tang Ze nodded and said, "Although I can't be too sure, at least that's the feeling I get."
"But why do I feel that the voice of the person behind me doesn't sound like Hanako Imamura?"
Naoki Kamii frowned and said, “But if it really wasn’t her, then Imamura Hanako is probably innocent.
