Heather Mazur is an American actress best known for her first-ever acting role, which was as Sarah Cooper on Night of the Living Dead.


Mazur was born on June 17, 1976, in Pittsburgh, Pennsylvania. She attended Carnegie Mellon University, where she received her BFA. In 1990, she launched her acting career, starring in the horror film Night of the Living Dead as Sarah Cooper. The film was a remake of the 1968 George A. Romero-directed film of the same name. Despite becoming well known for the role, Mazur quickly took a sabbatical from acting, which lasted for over ten years. In 2003, she received her MFA from the Yale School of Drama, after which she presumably resumed acting.

She restarted by making a guest-star appearance in the TV series Hack in 2003. Mazur then picked up the pace three years later. During that time, she made a number of guest-star appearances in several TV shows. These include Numb3rs, Joey, CSI: NY, CSI: Miami, Medium, Criminal Minds, Law & Order: LA, The Mentalist, and Bones. Mazur also appeared on the J.J. Abrams-produced TV pilot Anatomy of Hope, which ultimately was not picked up as a proper TV series. Mazur also had recurring roles in Crash and Pretty Little Liars. Her feature film credits include Over Her Dead Body, the direct-to-video film The Funeral Planner, and A Leading Man.

On Criminal MindsEdit

Mazur portrayed Kate Phinney, the childhood babysitter and current stepmother of serial killer Greg Phinney, in the Season Six episode The Stranger.
