Stanley "Stan" Burley is an NCIS Special Agent who worked on Leroy Jethro Gibbs's team for five years and also a former Agent Afloat who regularly assists Gibbs's team on various cases.
Not much of Burley's background is known but prior to joining NCIS, Burley worked as a Senator's Aide in Washington D.C. before applying to become an NCIS Special Agent which was accepted.
NCIS Season 1
Burley made his first official appearance in the Season 1 episode, High Seas (episode) where he was the Agent Afloat on the USS Enterprise investigating a case concerning a young sailor who'd overdosed on meth despite the sailor claiming that he had never even taken the drug in the first place.
Realizing time was very short and sensing something was wrong, Stan rang Gibbs, asking his former boss for help in regards to a case where two sailors named Wilkes and Shrewe had ended up in sickbay after suffering meth overdoses despite both sailors claiming that they had never even taken the drug in the first place.
Gibbs later agreed to help, bringing DiNozzo and Kate with him to help in the investigation. Petty Officer Wilkes soon died and Gibbs later stated that he believed that Wilkes had been killed because he was going to give up the name of whoever was supplying him the drugs at the time.
It was later revealed that Chief Petty Officer Reyes who was in charge of the ship's flight-deck crew was also the one responsible for giving his crewmen performance-enhancing drugs as he wanted them to get up to speed. He later ended up getting arrested.
NCIS Season 9
Eight years after his debut appearance, Burley returned in the Season 9 episode, Playing with Fire (episode) where he helped Tony and Ziva in tracking down and thwarting a terrorist who had tried to destroy the carrier USS Benjamin Franklin in Naples, Italy, under the orders of businessman/terrorist Harper Dearing. Burley was injured by the terrorist in the process as he was stabbed in the left shoulder and his service weapon was also stolen by the terrorist who intended to kill Tony and Ziva to escape but thanks to DiNozzo's efforts, the terrorist was captured.
Burley later returned with DiNozzo and David to the Navy Yard, and was part of the crowd which saw Gibbs place Dearing's photo on the wall of NCIS Most Wanted, hinting that Dearing had become a much bigger threat than the late Bin Laden.
NCIS Season 10
Burley returned in the Season 10 episode, "Squall" where he revealed to DiNozzo that he was engaged to be married after DiNozzo had mistakenly assumed that Burley had been hitting on Ziva. Similar to the plot of "High Seas", the team suspected a ship officer had been killed to cover up a drug ring.
- In one scene of "High Seas", Burley can be seen wearing a silver ring on the fourth finger of his left hand. It's not known if this is a wedding ring or something else.
- Burley wears his watch on his right wrist, hinting that like Timothy McGee, Burley might be left handed.
