I got this from adult video news, a recent issue If you were a porn fan of the '80s and 90's and not later, AVN Hall of Famer Karen Summers has died of a failing lung. Although she was battling breast cancer it was an unusual form of disease, hypercapnia. She was one of the few talented actresses and sex performers from the past. She always gave a cheerful look on film and videotaped . She will be missed.
