Dr. Steward Cone is the coroner who examines Chase Andrews’s dead body. While answering Tom Milton’s questions, Dr. Cone says that the red fibers found on Chase’s jacket—fibers that are made of the same material as a hat found in Kya’s shack—could have been left there as long as four years before the incident. Consequently, Tom is able to prove that the fibers themselves don’t definitively incriminate Kya.
