"Alright, alright."
Seeing the captain's gaze, the young officer raised his hands helplessly, "Everything you say is right, Captain. I was just mentioning it casually. According to what you've said, Captain, there should be traces of a third person at the scene."
"But we didn't find any trace of anyone other than the suspect and the victim at the scene."
"You should know that the average suspect wouldn't notice the presence of things like hair and dandruff, which are difficult to observe with the naked eye."
The middle-aged officer sneered upon hearing this, then stubbed out his cigarette in the crease of his hand, "This further proves that the real murderer has the ability to clean up the crime scene far beyond an average person. Someone with these capabilities has a very obvious professional characteristic, and it's clear they're no ordinary person."
"This allows us to quickly label the real killer."
"But only the suspect's fingerprints were found on the murder weapon."
