"Captain Qiu, we need to continue recovering the victim's body. Keep searching downstream along the river."
Li Xiang looked at the calm river surface and suddenly asked, "By the way, do we have any police dogs trained to search for blood traces?"
Upon hearing Li Xiang's question, Qiu Cang showed a troubled expression and said, "Our police dog base is still in the exploration stage for blood trace searching. Currently, no police dog can perform such searches."
Searching for blood traces is an upgrade over scent searching, further increasing the training difficulty.
It's not simply about finding traces of blood on the ground; such a search would be considered successful.
His success criteria are stringent; a drop of blood, diluted by tens of thousands of times, should be identifiable. That's just the entry level.
