The Girlfriend?

[Haunt Master]

I'm trying to remember the name of an actress from several years (probably late 80s - earlier 90s), I think she did slasher flicks, and I know he was known for the role of "The Girlfriend". I think she was the killer. She was a tall, slender blonde, and I think that her initals was D.S. (not sure). I know this isn't much to go on, butScary Movies are not usually my thing. Can you please help me?
Thanks!

I tried to look it up but found nothing with those initials. I'm not familiar with that movie.
