I was a big Hill Street Blues fan when I was a kid, and I recognized Dominique Dunne from Poltergeist when she was on the show. I saw the dedication afterwards, and was kinda bummed because she was obviously quite young, though I didn't know the circumstances surrounding her death (it was before the internet was invented [img]/images/graemlins/smile.gif[/img] ).
Once I found out what had happened, I was definitely saddened.
