JoAnna died at age 70.
And, like Melissa, JoAnna has ties to Colorado...she was born in Vail, but lived the last years of her life in Hawaii.
Cameron's co-star on the series, Joanna Pang Atkins, announced her passing on Twitter, writing, "Sad to post that JoAnna Cameron 'The Mighty Isis' has flown to heaven. She suffered a stroke and passed away from complications this past Friday. We shared the wonderful lasting experience of making 'The Secrets of Isis'."
