Sherk passed away on April 20 at the age of 43. Her husband, Oscar nominee Demián Bichir, broke the news in a loving tribute to her on Instagram Wednesday.
A model and an actress, Sherk starred as Jessica Turing in season two of CSI: Cyber opposite Arquette, 51, who had a starring role as Avery Ryan before the show ended in 2016.
In the scene, the character Jessica accused Avery of having an affair with Andrew Michaels, Avery’s ex-husband and Jessica’s fiancé.
“Jessica, Andrew is deeply devoted to you,” Avery told her.
“Normally, I wouldn’t doubt that, but things have changed since Andrew’s visit here a few weeks ago,” Jessica said. “He’s working late a lot, he isn’t interested in discussing the final details of our wedding.”
She added, “I realize he’s your ex-husband but I thought you had both moved on.”
Sherk had a number of acting credits to her name, including a role in Bichir’s directorial debut, Un Cuento de Circo & A Love Song in 2016. She’s also had roles in #Hashtag: The Series, Valentine’s Day, Star Power, Loco Love, as well as the upcoming horror movie Grudge, which she filmed with John Cho and Andrea Riseborough.
Her death was ruled a suicide with one of the causes of death listed as drowning.
Bichir, 55, called her “my beloved and loving wife” saying she had “passed away peacefully.”
“It has been the saddest and toughest time of our lives and we don’t know how much time it will take for us to overcome this pain,” the actor wrote. “Stefanie’s beautiful, angelical and talented presence will be immensely missed. We will hold Stefanie in our hearts forever.”

“We thank everybody beforehand for their prayers and we respectfully ask for your understanding so we may grieve in peace and privacy in these incredibly difficult times,” Bichir added. “It is our sincerest hope that our beautiful Stefanie, my angel and love of my life, will rest in eternal peace.”
Bichir and Sherk began dating in 2010. They did not have any children together, though Bichir has a daughter — Gala, born in 2011 — from a previous relationship.
