It's always a possibility, and it would certainly be an understandable one. (He could always have yet more plastic surgery and start life over as yet someone else.) Either way, we don't have to see him showing up in the media any more.
Having acknowledged that much, though, I have to say that I didn't think he'd live much into his forties. He showed all the signs of someone who was headed for an early death. (Can you imagine him living to be 80?) I'm surprised he made it to 50 and tend to think he lived longer than others with similar lifestyles do.
