Wersching got her start in television with a 2002 appearance on Star Trek: Enterprise in 2002 and later scored a recurring role on the soap opera General Hospital but her part as Agent Walker was her first main cast role. She would play Walker through the series’ final season in 2010. Wersching would continue to work regularly in television following the cancellation of 24 and was cast in recurring roles on Bosch, The Rookie, and Star Trek: Picard.

Agent Renee Walker was investigating the events that occurred before “Day 7,” and would join Jack Bauer, played by Kiefer Sutherland, to bring down the season’s principal antagonist – Alan Wilson. Walker often served as a foil for Bauer, questioning his results at any cost, but soon realized that his way was the most likely to stop Wilson.

Wersching’s former co-stars paid remembrance via social media following her tragic passing due to cancer. Sutherland called her “one of the greatest actors I’ve ever had the pleasure of working with” in a tweet made Sunday. Actor and comedian Mary Lynn Rajskub — who played Counter Terrorist Unit Analyst Chloe O’Brian on the series — remembered Wersching as “kind-hearted, funny, caring, and dedicated to her craft.” Both actors offered condolences to her family. Wersching was the mother of three sons with actor and comedian Stephen Full.
