Their statement was made on December 30th, 2013 and his was made after the autopsy was released in January of 2014.
What Loretta Fuddy told her brother about her medical history is unknown to us. We do not know what the dynamics of that family were. Maybe she only confided medical stuff to her sister. We don’t know.
But the fact remains shortly after the accident her family did tell investigators that she said she had a had an irregular heartbeat.
If you choose to discount the sister’s earlier statements to investigators - feel free to pick and choose whatever facts you need to confirm your theories.
Even a rock-solid "here's how it happened," (h/t the fictitious Detective Monk) that a jury has hears, judges guilty, and the court pronounces a stiff sentence, is reasonably called "a theory." If facts that truly contradict a theory become known, then it may not be called a theory. It's that simple.
There are conspiracies that have taken place and investigators that have figured out what happened, often getting indictments, prosecutions, guilty verdicts, and sentences, etc. A true narrative of such a thing would still be properly called a "conspiracy theory."
I may hold to "theories,"--as do well all about even some of the more mundane aspects of our lives--but I would give up any appropriate part if contradictory facts were to come to light. Would you? Or would you see a falsehood even be used as a basis for malicious prosecution if you had let it become your job?
Look at the newly-presented facts shown on this thread. There has been rife deception in this case. If you choose to work on behalf those that have done the deceiving, we right would ask, "What are you up to?"
As rodguy911 nicely excerpted above, "How many things are wrong with that scenario? And given how many of those wrong things there are, why should we believe her death is just exactly what those plane occupants said about it?
Although a group in 1967 started doing a very good job of making the term "conspiracy theories" a pejorative and a millstone around any neck that would hold to them, neither I, you, nor any other thinking person need bother gloat that a true narrative about an actual conspiracy has temporarily evaded justice.
Dr. Harle never even requested to see Fuddy’s medical records. If Fuddy knew she had an irregular heartbeat and needed to do something about it, it was presumably because she was diagnosed by a doctor - who in the diagnosing of it would have also treated her. The story on its face makes no sense. And if any of that had been true, then why didn’t Harle even ask to see the medical records, which would have confirmed her conclusions MUCH better than second-hand hearsay?
But the fact is that what the USCG swimmers drew up from the water was something that had on a lifejacket that Fuddy never wore. If Harle did an autopsy on THAT, it has nothing to do with Fuddy herself. Fuddy was wearing an adult lifejacket. Where did she go - since it obviously wasn’t her that the USCG swimmer lifted from the water and that Harle presumably “autopsied”?
