well, it's like with Elvis Presley. He has been known to be dead in '77, but there was rumors of apparition of himself in late '80s in a restaurant in USA somewhere in a town, then some people would have seen him driving bus in another country, then other places. Apparently either he was cloned and it was one of his clones, or he had to change identity completly because he was working with detectives to track down drug dealers
EDIT: you know, maybe he's Omnimaga staff now %)
(one of the younger staff pretending to be a teen while he's the true elvsi lol) jk
