I think that seems to be a recurring topic, with well-known people.
For years, people claimed that President John Kennedy was reported to be still alive, and living on Aristotle Onassis yacht.
Elvis has been spotted all over the United States , and supposedly photographed, ever since his death in 1977.
I remember reading that Billy Graham had died, several years ago, but apparently, that didn't happen either, even though there are thousands of other people who also read the same news, or saw it on TV .
Sometimes this is an outright hoax, but sometimes it seems to be an unexplained phenomenon.
