Mark, I'm sorry if you've lost your home, but (and I'm sure you don't want to hear this and I apologize in advance, but it's more for others reading this than for you) that's your fault, not his.
Unless he broke into your bank account (as Seamaiden said) or did some kind of identity theft, you chose to give this guy your money..........now I guess I'm weird, but sending any more than a couple of hundred dollars to a faceless, nameless Internet person/business is above my threshold.
Any higher than a few hundred and I'm gonna do my proper research to make sure said person is legit, I know their name, and I have at least some form of recourse (maybe not legal, but I'm gonna have some form of leverage - you can find out a lot about a person from a name and address like kids, family members, etc.) to attempt to get my money back.
I'm very sorry for your loss, but if you're one of the "small fries" and he scammed people for more than your $50K, I really have to wonder what goes through some people's minds to send that much money to someone they don't know.
Scam me out of a few hundred dollars, shame on you.
Scam me out of tens of thousands of dollars, shame on me.
Anyhow, kinda getting off-topic now - I'll say it for the last time (as GK has expressed it very well) - there's an unwritten code that you don't out people to the authorities/public, no matter what they've done - at least in the circles I run in - business is handled in-house.
This guy supposedly owes hundreds of thousands of dollars to you and others that you know and just now (incredibly) you're all finding out his real name?
PM them and send a goon squad to go collect...........don't send fucking cops to his house - how're you gonna get your money back that way?
