Eugene Keelson was a mysterious British information broker, who was capable of getting any kind of information on anyone but for the right price. He was also responsible for jeopardizing the Office of Special Projects's computers and as such, the virus he launched against the system granted him access to the files on numerous NCIS Agents and their operations which he presumably planned to sell on the black market. He serves as one of the primary and most dangerous, calculating and personal antagonists in the first season due to blackmailing Callen and nearly selling all the classified information that was in the OSP computers.

NCIS: Los Angeles Season 1Edit

When Callen's cover is blown, he's forced to cut all ties with NCIS. The man behind exposing Callen is a mysterious information broker, Eugene Keelson, who claims he has collected data on Callen that will reveal his past. Keelson's willing to trade that information if Callen performs one favor for him: deliver a flash drive to a group of Bulgarians mobsters. Callen does the delivery but the Bulgarians, believing he's Keelson, try to kill him.

Meanwhile, Hetty has Eric shut down all of NCIS's electronics as Keelson has sent a Trojan horse infecting all of Callen's files. Torn between learning more about his hidden background and his responsibilities as an NCIS agent, Callen knows he can't work the case. The flash drive has information about a hit the Bulgarians are meant to perform, and while Sam and the team work to prevent the hit, Eric discovers the entire NCIS operation has been infiltrated by Keelson. This forces Hetty to bring Callen back in.


Callen sets up a meeting with Keelson to buy back all of NCIS' sensitive information. At the meeting, Keelson sends Bulgarian gang leader Ruman Marinov, knowing either Callen or the Bulgarian will be killed. Callen survives after Sam intervenes and kills Marinov and then Callen chases Keelson. Finally, Callen is able to find Keelson, but after a cornered Eugene raises his gun, Callen is forced to shoot Keelson multiple times in the chest, killing him.


Due to killing Keelson, Callen lost his connection to the one person who knows about Callen's past, until Eric realizes there's a house where Keelson may have stored this information.
