Tiffany Chase was a flight attendant and also a contract killer who was hired to kill Nora Williams.
Much of Chase's past is unknown but at some point, she chose to become a professional hit-man, presumably so that she could make a better living for herself.
NCIS Season 7
At some point, Chase was contacted by Nora Williams's fiancee, Daniel Sturgis through Madam Holly Snow with Daniel offering Chase money in exchange for Chase killing Nora with Daniel fearing that he would be exposed by Nora's testimony.
Chase accepted the contract.
Before she boarded the plane, she killed another hitman, Marine Sergeant Mark Parsons and hid the body in kitty litter to avoid detection although the remains were later discovered by a cleaner.
During the flight, Chase prepared to carry out the hit and attacked Air Marshal Art Neely whom she killed by sticking a needle into his neck which killed Neely before she fled, hiding his body in one of the airplane toilets with NCIS Special Agents Anthony DiNozzo and Ziva David later discovering Neely's remains.
As a back-up plan and fearing her allergy reaction strategy would fail, Chase stole Neely's gun and lay in wait.
When Tony finally confronted her, she gave him the brush-off and attempted to fail, only to subdued by Ziva.
Chase is a woman in her thirties or forties with long, shoulder-length blonde hair.
As a hitman, Chase is skilled in all forms of assassinations and is also capable of using any weapon as a means of killing her target either slowly or quickly.
Hand to Hand Combat
Chase is an expert in hand-to-hand combat and can easily hold her own in a single fight yet when it came to Ziva who was not only an NCIS Special Agent but also formerly associated with the Israeli Mossad, Chase herself was outclasses and easily beaten.
