Tip his states attorney general to a possible scam ring using a fake theft approach as the scam. That might get some attention. Also call a newspaper in his state.

You need to SQUEEZE this dude using every avenue.
By the way I'd also help him out by reporting his "THEFT" to local LE. I am sure he would love a visit from an investigating officer if you could get them to head on out.
