Can't recall her in SAW!

I know. If you are not specifically looking for her it is easy to miss her as she is not consequential to the movie.

I think she had a bigger role in one of the sequels, but not a lot even then.

In which sequel?

She is in Saw 2 on and off throughout and then the first 5-10 minutes of Saw 3.

As a police cop?

She plays the old man dying of cancer, idiots.
