Actress Shell Kepler, who for years played the gossipy nurse Amy Vining on the TV soap opera "General Hospital," has died. She was 49. Kepler died Friday at Oregon Health & Science University hospital, which did not give the cause of death. Kepler's busybody character on "General Hospital" was a fan favorite and enjoyed a long run, 1979-2002. In addition to her run on "General Hospital," she was also in a 1982 Joan Collins film, "Homework," and a couple of episodes of the situation comedy "Three's Company."
