Or tried to kill. This is only about the original Scream because I don't care enough for the sequels.

Steve Orth & Casey Becker:
Both killed por Stu.

- Stu had mais personal motive to kill those two. (Casey dumped him for Steve.) The only motive Billy may have had is to throw Sidney mentally off, but for that anyone could do and he could easily let Stu do the dirty part. I'm quite sure it was Stu's idea to pick Casey and Steve as the victims. Aldo, see the look in Casey's eyes when she removes the Ghostface mask to see who's butchering her. It is a look of regocnizing the person and regret/shock....
