Below is the message her son, Alex, posted to her Facebook wall on Monday morning.
Old friends, long time fans, today at 4am Margot breathed easily for the first time in two weeks. Later today, at 10:30am she was pronounced deceased.
Her condition had been getting much worse over the weeks and months and the brain radiation (which she had a treatment of scheduled today, tomorrow, and wednesday) was thought to help her double vision, since it was the cause.
Well, Margot and John both won’t be seeing double anymore, but they will be seeing each other for the rest of time.
With much love and difficulty do I write this,
Her son, Alex
