It's a strange one to throw out there so late into the inquiry. If medical conditions that made her prone to blacking out then again I could see why they'd think she fell into the river. If it was mental health problems then surely straight away they'd have said she was a vulnerable person, as that could explain why she might have just took off. The police by throwing this curve ball out there have just thrown fuel onto a fire they were trying to dampen down. Most odd.
If police advised that previously diagnosed with condition that made her particularly prone to blackouts.
Then as she regularly drove children to/from school & on day she went missing, wouldn't this condition
have disqualified her from driving? I know some people don't bring visibility of such conditions to DVLA
as dont wish to be disqualified. I also seem to recall that in first press conference they, in response to a
question on her ability to swim, confirmed that she could swim and was physically fit?
As you say, by first giving public visibility of vulnerabilities but then not confirming due to privacy issues,
it seems to open social media flood gates, that press conference aim, they said, were trying to quieten?
I believe real aim of introducing the "we were aware of her vulnerabilities" is to protect police service
from media speculation that they didn't treat location of phone/dog initially as crime scene as they had
information of her vulnerabilities, whatever they were/are and so supports original press conference &
today, that she entered the water either voluntarily or accidentally
