"A53 and B167."
"A33, A34, and B13."
"Set the clubs aside separately, don't mix up the numbers, let me have a look."
"A11 and B208, conduct a micro-trace evidence test on each."
Jiang Yuan efficiently examined the various groups of photos, the evidence that covered the long conference table, continuously photographed, numbered, and recorded.
In most cases, Jiang Yuan didn't need to open the evidence packaging or would examine the evidence after it had been properly sealed. In this way, after confirming the identity of the tool marks, he could validate the findings with micro-trace evidence.
The cost of analyzing micro-trace evidence was not low; even for his own lab, it could cost hundreds of dollars per test, and just a slight increase in the number of tests could easily amount to the price of an Audi, not to mention the construction and maintenance costs of the lab.
