Abigail "Abby" Sciuto is the Chief Forensic Scientist for the NCIS Major Case Response Team.
Abby was born in New Orleans, Louisiana.
She was later given up for adoption by her birth parents and taken in by an unnamed family, raising her as their own along with their birth son Luca Sciuto.
Her foster parents were deaf with young Abby subsequently learning American Sign Language to communicate with them.
During her youth, Abby moved and got a chance to experience most of the southern United States. At the age of ten, she learnt how to drive a manual transmission.
Upon finishing high school, she went to college, graduating with full honors from Louisiana State University with a triple major in Sociology, Criminology, and psychology.
She had earned her Master's degree from Georgia State University in Criminology and Forensic Science.
A while after, Abby joined Naval Criminal Investigative Service.

Abby has a gothic style of dress, including black dresses and T-shirts, miniskirts, and goth jewelry, including anklets and toe rings. She wears pigtailed dyed hair (due to Perrette's hair being dyed as she is a natural blonde) and has at least nine tattoos on her neck, arms, back, ankle, and other places. Her neck choker appears to be one of her favorite pieces of jewelry. While some of the tattoos are Perrette's and real, others are makeup, such as the large cross on her back applied on occasions when Perrette shows her bare back on camera. The spider web on her neck is not real, either, as producer Bellisario wanted the character to have a tattoo that would be visible (almost) all the time.
