Vincent "Vince" Masuka (Masuoka in the books) is a fictional character in the Showtime television series Dexter and the novels by Jeff Lindsay upon which the series is based. On television he is portrayed by Korean American C. S. Lee. Masuka is the Miami Metro Police lead forensic science investigator; he works alongside Dexter Morgan in the lab and at crime scenes. He often cracks tasteless and inappropriate jokes, invokes his Japanese heritage only when convenient, and harbors unrequited desire for Dexter's foster sister Debra. Although goofy and obsessed with sex, he is clever and very good at his job, causing Dexter to worry from time to time that Masuka will uncover his secret.
