Mario-Francisco Robles, nephew of Elizabeth, posted her obituary on the Latino Review.

He wrote, "Tonight, my family is heartbroken. There's now a void that will never be filled. All we can do now is remember your sharp sense of humor, your endless hunger for life, and your never ending pursuit of happiness."

Her nephew's eulogy wrote, "She undoubtedly helped fuel my love of film. She informed my desire to be an actor, writer and director. I followed in her footsteps at the High School of Performing Arts. It still remains my life's goal to earn a living doing what I love.
