carlie cooper - a very close lifelong friend of lily hollister, carlie works as a forensics expert in the crime scene unit. new to her job, she shows interest in the more "exotic" cases, but has to start at the bottom. her father is ray cooper, a deceased cop who was well respected by his peers. while preparing a body found in the river for the medical examiner, she finds a spider-tracer in its mouth, which initiates the police warrant for the "spider-tracer killer" (believed by most to be spider-man).
