According to Jiang An's earlier suggestion, the evidence was systematically divided into four parts—more precisely, three main parts and one smaller part, and they were arranged to be sent for examination in batches.
Before sending it for examination, Jiang An specifically reminded each criminal investigation team leader, emphasizing that during the inspection of these hundreds of pieces of evidence, if a third party's blood type appeared, they must contact him immediately.
He knew well, at critical moments in solving a case, every second counts and any delay could result in the loss of crucial clues.
If a third party's blood could be found and analyzed for comparison, it would undoubtedly provide essential evidence for a breakthrough in the case, and could even become the key condition for immediately initiating the next step in the investigation.
Time quietly slipped away.
