Marty Deeks is the only child of Roberta Deeks and Gordon John Brandel and grew up in Los Angeles. In his childhood, Deeks suffered abuse from his alcoholic father who harmed both himself and his mother Roberta Deeks. Although he continued to suffer, Deeks became best friends with Ray as both were abused by their father's. Eventually the abused worsened when his father threatened Deeks and his mother with a shotgun. In response, an 11 year old Deeks reacted quickly to protect himself and his mother and non fatally shot his father who was sent to prison. Since then, Deeks lived with his mother and got to live a happier life where he grew interested in model trains, played the violin and even became lead guitarist of his high school band. Deeks also became close friends with Kip Brigham who later went on to become a famous NBA basketball player. In his older years, Deeks decided to become lawyer and in order to pay for collage tuition, he did exotic dancing. Deeks graduated and became a public defender. During his years as a public defender, Deeks became close with a homeless woman, Jenny Radler who often found herself in trouble with the law. Deeks was her regular defender and at one point helped Jenny to keep custody of her daughter, Talia Radler when Child Protective Services attempted to take her daughter away and they have since remained in touch.
However, at some point Deeks decided to quit and later joined the Los Angeles Police Department upon being inspired by his two favourite television shows, CHiPs and TJ Hooker. When he began working with the LAPA, he worked in the Robbery Division for two years and later was promoted to detective and was first partnered with Francis Boyle. However, Francis Boyle was known to be an extremely bad and was suspected to be a dirty cop alongside his partner, Bruce Steadman. In hopes to prevent any further problems, Bruce and Francis were separated as partners and Francis was assigned to the newly promoted detective, Marty Deeks. On his first day as both a detective and partners with Francis Boyle, a suspect was brought and confessed to a crime when Francis used extremely violent rough old fashioned methods with hot coffee. Deeks reported Francis and shortly after Francis threatened Deeks, putting a gun in his mouth.
While they were partnered only together for a short time, Francis grew worse and threatened to kill Tiffany Williams, a prostitute informant of Deeks. In order to protect Tiffany, Deeks killed Francis and covered up the murder while giving Tiffany a new identity and life for herself. Later, Deeks became partners with Roger Bates who later went on to become a Lieutenant and they developed a hate-love partnership. However, due to his past with Francis Boyle and overall his personality and differences, Deeks was viewed as an outsider by the police department. Deeks never truly fit in with the rest of the detectives as no one wanted to work with him, resulting in Deeks transferring to work undercover division.
Deeks soon became a great detective, managing to take down and arrest lots of criminals and although he isn't always well liked by LAPA, he is acknowledged as a good detective and cop and does look out for his fellow boys in blue. At somepoint in his career, Deeks also became close friends with Michael Donaldson, an NSA Agent who attempted surfing, but failed and suffered from a sunburn, but was saved by Deeks. Since then, Deeks and Michael have been friends and jokingly referred to each other as doctors due to their mutual initials M.D. Three years previously, Deeks was the informant of an internal affairs investigation for Detective Jeff Vesery who was an alcoholic. Although some believe Deeks ruined Jeff Versery's career, Jeff started to respect, seeing Deeks helped him to become sober and is the closest person he has to a sponser. Sometime later, Deeks was assigned to an undercover assignment for a Mix Martial Arts gym for military men which is rumoured to sell drugs.

Deeks is further upset he is unable to acquire information about where Kensi is or if she is alright.

During the mission to rescue Kensi, the team finally learn the truth about her assignment. Kensi was sent to Afghanistan to assassinate a mysterious person known as The White Ghost who is said to have connections with a dangerous group, Taliban. It's revealed the White Ghost never existed and instead it was a cover for the CIA to kill Jack Simone a former marine who previously worked for them and used to get important information. However, since Jack had knowledge of classified intel on the CIA and refused to return to the United States, the CIA created the fake identity of The White Ghost and a joint task force with NCIS to kill him to secure CIA knowledge while NCIS was under the ruse of killing Jack due to his supposed connections with the Taliban terrorist group. Knowing Jack in the past, Hetty sent Kensi to try and help Jack escape the CIA's grasp on him and survive without Kensi's knowledge as previously 10 years prior, Kensi and Jack were engaged, but broke up when Jack suffered from PTSD and converted to Islam.

Deeks questions is there more to the situation than what Kensi experienced in Afghanistan, but Hetty doesn't answer his question. Eventually, Kensi manages to prove herself to Hetty and Deeks is happy to have Kensi and their partnership back.
Finally after Kensi has managed to recover and fully resume her place on the team, Kensi and Deeks once again confront their romantic feelings for each other. Deeks attempts to ask Kensi on a date, but find themselves interrogating Angelo, a possibly rouge NCIS Agent and may have turned to the dark side. Kensi and Deeks are sent to interrogate Agent Angelo, but find themselves having difficulty with him and he attempts to manipulate them using their relationship, realizing the romantic feelings they have for each other and tries to convince them their relationship will not work. While Kensi doesn't let him affect her, Deeks does become affected by Angelo and his thoughts and beliefs about his and Kensi's relationship. Deeks starts to reconsider his and Kensi's relationship due to their jobs at NCIS, knowing that agents can't become romantically involve knowing if the relationship ends badly it will affect them and their capabilities.
Ultimately after interrogating Angelo, Deeks becomes unsure about his and Kensi's relationship and rethinks after everything they've been through together this past season, especially their separation and nearly losing one another on different occasions. Deeks symbolises his uncertainty about his and Kensi being together and returns Kensi's knife she gave him before she left for Afghanistan, indicating he may not be ready after all for them to be truly together and needs more time. While both are disappointed, Kensi again shows her feelings and trust in Deeks by opening the mysterious package that has remained unopened since it's arrival in season four and opens The Box and gives it to Deeks and leaves. He opens it to find another smaller box, but doesn't open it and instead leaves the building shortly after Kensi. However, unaware to Deeks, Hetty and Granger who have been heavily discussing Deeks and Kensi's relationship throughout the entire season witnessed them together. Granger wonders if it's The beginning of the end, but Hetty believes their relationship has reached The end of the beginning, indicating Deeks and Kensi have started a new chapter of their relationship that remains to be seen.
