Quincy, M.E. (1976)

S6E2 A Matter of Principle

Sam works to convince the authorities of a groundbreaking method he's created to assist in identifying murderers. His tooth print analysis reveals that the individual the police have in custody for a rape case is innocent; the bite mark must belong to someone else. Despite the significance of his findings, his unfamiliar technique faces skepticism and isn't readily accepted by law enforcement.
