According to a statement from her spokesperson cited by media reports, Raven died on Tuesday in Los Angeles. USA Today cited her family, who said that she died peacefully in her home.

Since the early 1960s, she had small roles in movies such as Amityville Horror and In the Line of Fire, as well as in TV shows, including Wiseguy and Amen.
