in addition to contacting that state's attorney, I would immeidately contatc the local authorities and initiate a legal action for fraud with the county or city police departments, respectively. or both! this seems the first thing to do. you have an address, and formerly phone numbers you can provide the cops along with more information.
as it is as well inter state commerce perhaps in addition, there are Federal offices for fraud you could contact.
I do recall a member here that had sent along his amps to a similarly abruptly vacated enterprise, i.e., Thor Audio, for upgrading purposes. reaching out to the local cops there resulted in him getting back one or maybe both of his mono blocks as he had their full description, serial #, and shipping information, receipts etc.
there was possibly more to that affair but the above info was conveyed to me by the person whose gear was made unavilable by the abrupt unannounced departure of Paul Marks.
GVery sorry to hear of this issue. it is the single yet remarkably devastating concern enthusiasts face with a cottage industry manufacturer. whose infrastructure is severely limited. ood luck.
