Detective for Miami Metro Police, Homicide Division
Miami Metro Police
Detective McNamara or as he's normally called, Mack (shortened version of his last name) is a character on Showtime's series DEXTER.
McNamara is a white male in his thirties to forties, with blonde hair and blue eyes.
Mack is the brother of Kara Simmons and he had a personal vendetta against Sergeant James Doakes for sleeping with his sister while her police officer husband was working undercover. Under the orders of Carlos Guerrero, both Kara and her husband were murdered. In finding a way to arrest Guerrero, McNamara set up Guerrero by tricking him into beating up Doakes. After this, McNamara told Doakes that they were "even."
"Got you going after a goddamn cop, motherfucker!"
