Quincy, Chief Deputy LA Medical Examiner - It has been stated in many television publications that Jack Klugman's portrayal of the mischievous protagonist is far from perfect. This maybe true but as fans are quick to note, Quincy represents the driving force to solving crimes with scientific fact, not blind faith!

Sam Fujiyama, Lab Assistant - "Lab, Fujiyama here..." is typically what we hear when the phone rings. It's also where we find our friendly right-hand lab assistant, Sam. Sam represents "Robin" in this DNA duo* crime drama. While sometimes quick to anticipate Quincy's next move, he has been noted to take sides with his and Quincy's boss, Asten, in matters of diplomacy.

Marc, Assistant Medical Examiner - Marc is responsible for assisting the Chief and Deputy Medical Examiners during autopsy examinations within the LA forensic lab. While his role became more prominent after Sam's objectivity on the job came under public scrutiny at trial, he was one of the few brought on-board LACC for his dedication and degree of expertise in the field of forensic science.

Eddie Garrett, LACC Crime Scene Photographer - Eddie has the difficult task of trying to capture the essence of a crime scene before Quincy conducts an autopsy to determine the victim's cause of death. He photographs all investigations and while each still may not seem particularly critical during an ongoing investigation, these "snapshots in time" offer a glimpse of post-mortem evidence used to support the chief medical officer's findings.

Dr. Robert J. Astin, Director of Operations - Asten is Quincy and Sam's boss and has the claim to fame of being adversarial with Quincy. But close examination of Asten's character during the series, provides an alternate viewpoint - one of compassion and admiration toward his best deputy LA coroner. Continually, Asten has to walk two very different and difficult paths at the same time, that of administrator first and doctor second.

Lt. Frank Monahan & Sgt. Brill, LAPD Liaisons - Monahan & Brill are usually the first on the scene of a homicide. It's usually their lead work that makes Quincy's job a little easier. As a matter of fact, if Monahan and Quincy weren't good friends, they'd be at each others throats. Monahan's only gripe is that Quincy should stay with medicine rather than detective work. I think he's just jealous though.

Dr. Emily Hanover, Psychologist - Sometimes trying to pin down scientific fact and logical reasoning isn't always possible in cases of the determine criminal intent. Dr. Emily Hanover, has become something of a guiding light to Quincy and the rest of the gang in cases that involve trying to understand the workings of the human psyche.

Danny Tovo, Restaurant Owner - Running a restaurant and bar is no easy matter and if you're Danny Tovo, that makes it doubly difficult. Danny is a good friend. He tries to maintain a respectable law-abiding clientele, but with Quincy's small boat, Danny's has become Quincy's second home away from the lab. Poor Danny! If only Quincy was a little more responsible about who he invited to the restaurant.
