There's no confirmation of that. This is literally just a "Michael Bolton" situation. It could be him or an unrelated person.

My point is that the media has repeated it as fact, while the registration information used his full name (including middle) and birthday. Maybe address too (I forget). They just want to stir up drama before confirming anything.

You learn these things doing genealogy. You need a high number of data points to confirm who someone is. People get all excited if they have the same last name as a famous person. There are literally a million people with similar last names.
