- "Hi, I'm Amanda."
- —Reed/Voss introducing herself to NCIS Special Agent Anthony DiNozzo aka "Stringfellow".
Amanda Reed/Hamilton Voss was a woman who was once a man by the name of Hamilton Voss, a Lieutenant Commander in the United States Navy who was suspected of being involved in a credit card scam as well as stealing money from the Navy.
In order to avoid being arrested, he contacted his old school classmate, Joshua Lurie and had him help stage his own death.
To this end, Voss burned a man to death to make him unidentifiable other than DNA which Joshua used to purposely misidentify the victim as Voss by switching their DNA to fool the local authorities.
Voss then killed Joshua and staged it as another car accident to cover his tracks.
This helped take the heat off Voss for a short while yet fearing that someone would come back to look for him, Voss underwent gender assignment surgery a couple of years later in Bankgok and after becoming a woman, later assumed the name Amanda Reed, settling into life in Washington D.C.
Eventually, at some point, Reed's own fears came true when NCIS Special Agent Christopher Pacci discovered the truth about her past along with her real identity.
Fearing that her secret would get exposed, Reed followed Pacci in a building and shot him just as he was leaving a stairway, the bullet entering through his neck and leaving a trail of blood in its wake.
Pacci eventually succumbed to his injuries in a lift and died with a desperate Reed attempting to get a memory stick that Pacci had swallowed.
But due to the alarms going off, she fled the scene, retreating to her flat.
Pacci's NCIS colleagues, the NCIS Major Case Response Team eventually took over the investigation and began staking out her home, believing she had connections to the one responsible for Pacci's murder, not realizing that Reed/Voss had personally committed the crime.
Anthony DiNozzo later fell for Reed and the two began going out together but the relationship hit a very sour note and came to an abrupt and permanent end when Abigail Sciuto informed Leroy Jethro Gibbs and Caitlin Todd that Lt. Commander Voss and Reed were the same person.
This later triggered a standoff in a bar when Reed attempted to kill DiNozzo to keep her secret safe but Gibbs who had gotten there first, shooting Reed in revenge for Pacci's murder which resulted in her death.
