Abigail "Abby" Sciuto is the Chief Forensic Scientist for the NCIS Major Case Response Team.
Abby was born in New Orleans, Louisiana.

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.
