Casey Cooper, better known by her nickname Cici, was a supporting character in Scream 2 (1997 film). She was a first-year film student at Windsor College, approximately 19 years old. She was a sorority sister at Omega Beta Zeta, and dated a man named Ted, who appeared to be an alcoholic.
While on sober sister duty, she was murdered by Ghostface. In their previous film theory class, she sided with her classmate, Randy Meeks, over Mickey in their discussion on sequels. She rejected the idea that movies caused crimes, saying that people are ultimately responsible for their own actions.
Overall, she was the third character to fall victim to the second Ghostface killing spree, also known as the Windsor College Murders. She was a target due to her forename replicating Casey Becker, the first target of the original Woodsboro Massacre. She sided with Randy Meeks, one of the survivors of Woodsboro on the discussion of movies not being responsible for our actions, and her dislike for sequels.
She was portrayed by Sarah Michelle Gellar.
