She can be killed in Final Interview after Niko Bellic kills Tom Goldberg. She runs in and finds him dead and runs away. She could easily get shot in the shootout. This will not fail the mission or affect the storyline.
Being a minor character, she does not have a unique appearance and shares her model with a businesswoman found around Liberty City.
Her model is randomized during each appearance, although her appearance is almost always a blue-eyed woman with brunette hair, wearing hints of makeup.
