Family members say a Fargo woman who survived a rollover crash near Bismarck a week ago, died four days later from an existing medical condition.

Sixty-six-year-old Patricia Westerholm was involved in a crash last Friday and was treated and released from Sanford Hospital in Bismarck. Her son, Tom Westerholm, says his mother then left for her mom's house in Waterford City where she was originally headed before the crash.

WDAY-TV reports Westerholm collapsed at her mother's home Tuesday. She was taken to McKenzie County Healthcare Systems hospital in Waterford City where she died later that day. Her son says his mother died from a ruptured aortic aneurysm and had a history of aneurysms.
