Lara Macy
Special Agent Lara Macy (portrayed by Louise Lombard) does not appear on NCIS: Los Angeles, but was introduced as Hetty's predecessor as OSP Operations Manager in the back-door pilot "Legend" on NCIS.
She was a former USMC Lieutenant working as a military police officer, and almost two decades earlier had investigated then-USMC Gunnery Sergeant Leroy Jethro Gibbs' role in the murder of Mexican drug lord Pedro Hernandez. Due to the past investigation, their relationship was volatile until the OSP's operational psychologist Nate Getz revealed to Gibbs that Macy had been protecting him for eighteen years by covering up the evidence. Since Hernandez was responsible for the slaying of Gibbs' wife and daughter, Macy felt that his actions against Hernandez were justified.
In the episode "Ambush", Hetty remarks to Director Vance that the last she'd heard, as the result of a political "witch-hunt" Macy was "working out of a quonset hut in Djibouti." This was contradicted on a subsequent episode of NCIS, where Macy's personnel file states that she never worked in Djibouti but was instead reassigned to Marseille, to head up an NCIS undercover team there.
In the NCIS episode "Patriot Down", Macy was brutally murdered in Annapolis and her body set alight by Jason Paul Dean, a mercenary and former U.S. Army Ranger, as part of a plot to get to Gibbs in relation to the Hernandez case.
