The following information supports your theory:
"In the last week, Reeve had developed a serious systemic infection from a pressure wound, a common complication for people living with paralysis." (CNN)
'In the last week' takes us back to October 4. Kerry, being a close friend, may have learned of this serious infection mid last week, based on the information above, prior to its release in the public domain.
Just my 2 cents.
Thanks. I am even more convinced now that this was orchestrated.
