Her father died the Christmas before she joined the NCIS team: he had a heart attack while on his mail route.
Kasie first appears as Dr Mallard's graduate assistant while he is taking time away to write a book. She later appears at the end of the season when Dr Mallard returns to NCIS and remains to temporarily take over Abby's role as the main forensic scientist for the Major Case Response Team.
Kasie is promoted to a main character and her role as Forensic Scientist is made permanent after several months (in show time).
Kasie is a very friendly type of person. She is expressive and has inventive one-liners. She was initially cold towards her predecessor Abby Sciuto, however this was due to being a fan of hers and internally freaking out when meeting her.
Kasie is an African-American woman in her early twenties, with natural, curly dark hair. She wears glasses, and usually a lab coat over her colorful, bright clothes..
Relationships with NCIS ColleaguesEdit
