Another Corvette Off Topic member here. I hope this guy gets what's coming to him after all this.
Please remember to leave the rest of his family out of this. It is possible that he has scammed them to some extent as well. Driving by his house is not a good idea. I'm sure he's already made their lives miserable up to now.
It is possible to have a heart attack, and be up walking around a couple of days later. They vary in intensity.
An idea was brought forward about approaching the credit union and asking them to forgive the loan as a taxable write off for advertising if the car is auctioned for charity. This would be a win/win situation for all involved, especially Joes mother who would have the bulk of the burden.
People have suggested sending repeated text messages to Joes phone. It's obvious that he can't pay his bills now in an honest fashion, so why make the phone company another victim.
Let's let the legal system work itself out in this regard. I doubt very much that he will be able to scam anyone after the amount of publicity that his actions have brought.
I hope other scammers take a lesson from this, and try honesty for a change.

Just my .02 cents.
