Robert David Hall, star of "CSI"

There are speculations about some other characters that may have disabilities, but i do have to agree that it is more likely that characters are portrayed by nondisabled actors.

Why they don't mention Sue Sylvester's sister, Becky, is questionable, but I'm guessing it's because she's not a main character, only recurring.
