what Briscoe proposed; nevertheless, Briscoe views Furillo as arrogant and self-righteous. He is loyal to the chief, though nowhere near as cynical. The same actor also played a police captain named Roger McPherson in one episode. Wally Nydorf (Pat Corley 1982-86) A county coroner who, because of budget shortages and lack of staffing, is constantly behind in his work. Known as having once been a brilliant medical examiner. Though Nydorf is polite to visiting police officers and infuses gallows humor into his conversation, he can turn on a dime and become loud, impatient, and irascible. Rob Nelson (Louis Giambalvo) Rob is the husband of J.D.'s sister Peggy. He runs a car lot, and his business practices are often called into question, as is his devotion to Peggy. J.D., ever the opportunist, often approaches Rob when Rob is in a tough situation (such as when he is arrested for soliciting a prostitute), and promises him help, but only in exchange for a free car. J.D.'s schemes involving Rob almost always fall through in one way or another. James Logan (Nick Savage) A pickpocket and purveyor of stolen merchandise who is frequently arrested by Belker. Apart from his last appearance, he gives Belker a fake name, usually a comical one which refers to his merchandise. When in possession of stolen skiing equipment, for instance, he claims to be named Jean-Claude Killy; when arrested with stolen golf equipment, he claims his name is Sam Snead. Shot and killed in Season 4; he died in Belker's arms. Cpl. Jock Buchanan (1981–87) A patrol officer who is often seen in the background. He has a mustache, a strong jaw, and his blonde hair is a bit on the long side. He gives the impression of being a bit older than most of the other cops. Buchanan, apparently one of only a couple of corporals in the precinct, almost never has a line that rises above the background noise. Officer Art Delgado (Jerome Thor, 1982) A police officer who is referenced in passing several times, but is first seen with regard to a commission investigating corruption. Delgado has 29 years on the force but, due to a one-year leave of absence, only has seniority for 19. Very close to the end of his career, he has a breakdown and is unable to function (though he remains alert and personable). His brother officers sign him in and
