The author has made such a cat's breakfast of the facts that I have no idea whether she's competent to follow a paper trail.
I have no idea whether the address is actually Michael Schiavo's address, or whether it's even the same Michael Schiavo, but a Michael R. Schiavo is indeed listed as a director of Jerger-Centonze Insurance. If you look on the Florida State Division of Corporations website, it's as clear as day that Jerger-Centonze did not mis-spell "Insurance" on their papers, that appears to be a typo by a state employee who indexed the filing.
Having missed that, what else have the writers missed?
I assure you that it is the same Michael R. Schiavo. I've been following this for some time. While Ms. McLeod does leave a bit to be desired in the way of reporting, it doesn't mean that she's totally off base here either. Until this story, I had missed the Washington Post article, which I intend to look at for the paper trail, to see if it corroborates Ms. McLeod's story.
Don't throw out the baby with the dishwater. There could still be something here that is unseen as of yet.
