I remember that interview so vividly as I was observing her body language because I felt she was guilty. I remember thinking she mixed up their names, but scant details were published then and thought maybe she’d been kept updated by Simon/family and maybe she was in fact correct.But at one point she talks about how sad it is that Heather, Gail and Ian have died and she hopes Don survives.
Just just flat couldn't be bothered to remember which close relatives had died.
I also wondered whether it was her reaction, and her shock, which seemed void of any deep heartfelt response because she was stunned and mortified that she may be responsible.
