Yea, that sucks, she was a cutie and a really nice person. There was no cause of death listed, she was only 49, a few years older than me, yikes! I fondly remember watching her on General Hospital back in the 80's.
I did some checking on the internet, that mentioned renal failure (kidney) as the cause of her death, which apparently had happened on Saturday February 2, 2008, even though the information did not appear until Monday February 4th.
