The Karen Ann Quinlan show comment was supposedly made to her mother when she was 10-12, and to her childhood friend, who at first said it was later, but when the dates and quotes were examined, it made no sense. The court found that that comment was most likely made at the same time when her friend was visiting the family for the summer.
Her husband and his family were referring to comments she supposedly made regarding other family and friends after they were married - her uncle and a baby of a friend.
I tend to think none of them are telling the truth.
