"Yeah, and the distribution is so chaotic, it doesn't look like simple drips or wiping."
Chen Biao touched his chin and thoughtfully added.
"Could it be interference from other substances?"
"Such as some chemical residues or the owner's daily supplies?"
Jiang An shook his head, his tone firm: "The possibility is very low."
"If it were interfering substances, other areas of the trunk should have similar reactions."
"But aside from the bottom and here, there's almost no fluorescence elsewhere. Besides—"
He paused, pointing to the marks on the lid, "These fluorescences, though faint, match the characteristics of bloodstains, just with very little contact."
Chen Biao and Wu Bin exchanged glances, faces full of confusion.
"If there really are bloodstains, why would they appear on the inside of the trunk lid?"
Wu Bin muttered to himself, "When the victim was stuffed into the trunk, the bloodstains should be concentrated at the bottom instead..."
