Paula Cassidy was an NCIS Special Agent who was originally assigned to Guantanamo Bay as an interrogator.
She later returned to Washington D.C. before being reassigned to the Pentagon where she led her own team before she died in the line of duty in April 2007.
Not much is known about Cassidy's history but according to her file, she was born in an area of Canada.
She later emigrated to the United States, presumably gaining citizenship and ultimately joined NCIS.

Cassidy made her debut appearance in the NCIS Season 1 episode, "Minimum Security".

NCIS Season 3Edit
In the months following Kate's death, Cassidy served as a brief replacement on the main NCIS Major Case Response Team and she became DiNozzo's temporary partner.
NCIS Season 4Edit
Cassidy's final appearance came in the Season 4 episode, "Grace Period" where it was revealed that she worked out of the Pentagon, commanding a team of her own which was composed of herself and NCIS Special Agents James Nelson and Rick Hall.
Tragically, both Nelson and Hall were subsequently killed by a suicide bomber with their deaths greatly devastating Cassidy and also leaving her stricken with grief and regret.
Cassidy was a short woman in her mid-thirties with blonde hair she later dyed brown and light blue eyes.
As an NCIS Special Agent, Cassidy was highly skilled in interrogating various suspects.
