List of Appearances

Martin "Marty" A. Deeks is a Detective with the Los Angeles Police Department and who serves as a liaison to NCIS via the LAPD which means that Deeks is responsible for facilitating communications between both agencies, and coordinating joint operations involving LAPD components.



The son of a man named Gordon John Brandel and Roberta Deeks, Deeks was born on January 8th, 1979 in California but Deeks didn't have a happy childhood as his father was an alcoholic who frequently abused Deeks and Deeks's mother, Roberta.

One day, Brandel became so drunk that he started wielding a shotgun at Deeks and his mother.

In response, young Deeks shot Brandel non-fatally with Brandal later ending up in prison.

Deeks later presumably moved away and attended college and law school. He became a public defense lawyer before choosing to join the Los Angeles Police Department.

NCIS: Los Angeles Season 1Edit


Deeks made his debut appearance in the NCIS: Los Angeles Season 1 episode Hand-to-Hand (episode) where he posed as "Jason Wyler" to infiltrate the Blood and Guts Warriors Gym, a Mixed Martial Arts Fighting Gym that the Los Angeles Police Department believed was a place that the Juraez Cartel used to smuggle drugs.

In Angels and Daemons (episode), Deeks and Kensi arrived to work where they overheard Callen and Sam arguing about something with Kensi assuming that Callen was going rogue again, causing Deeks to wonder if he could overshadow Callen this time as it'd be the only way Deeks would learn.

Deeks later learnt that Callen had become pre-cautious after their names had been leaked last year and that Callen was keeping tabs on a man named Gareth Odell, the newest boyfriend for Callen's ex-girlfriend, Joelle Taylor with Deeks remarking that Callen was right to do so although Kensi believed that Callen was being jealous.

Deeks along with Callen, Sam and Kensi later gathered in Ops where Eric, Nell and Granger briefed them on their newest case: the death of former Navy Commander Larry Overson whose body had been pulled from the water in a marina by the United States Coast Guard.



Deeks is a tall man in his early thirties with short blonde rugged hair and blue eyes.

He is often seen wearing jumpers, jeans and shoes.

When participating in a raid in the field, Deeks dons the official NCIS bulletproof vest and just like Callen, Sam and Kensi, also has a holster around his right thigh.

He also originally carried a Glock 17 before switching to a Beretta 92FS but in Season 3, exchanged his Beretta 92FS for a Smith & Wesson 5944 which he has continued to use to this day.
