So, when was he on 106.7 ???
He wasnt.
A shock jock makes a lot of jokes that offends people. Unfortunately there is one group of people you cant make any jokes about. (make that two, with the gays now).
Its been ten plus years. He did his apology tour. Get over it.
If you actually did care "whatever happened to" him, try wikipedia.
