Just as Gao Yang was giving Doctor Kelson a detailed explanation of what had happened, four people split into two groups and began the cleanup work.
The person Kelson called an evidence collection expert lay on the floor, holding a small jar in one hand and a cloth in the other, crawling on the ground and nearly inch by inch, he searched and cleaned the surface.
Moving slowly to the spot where Dusselyev had been placed, the expert carefully picked up a strand of hair with tweezers and placed it into a clear plastic bag.
After seeing the expert's actions, Kelson gestured for Gao Yang to pause speaking, then shouted at the expert, "Hey, hey, Jeremy, you're here to eliminate evidence, not to collect it. Our client is watching! What do you need that dead guy's hair for?"
