If memory serves me right, when I was searching for the AG for South Carolina, I found the SC Department of Consumer Affairs. If I'm not mistaken, they are a branch of the AG and they are the ones that handle this sort of thing. The only "internet crimes" I could find on the AG website is crimes against children. But I'll have another look around and see what I can dig up.
The other guy that contacted me, wanted to know about how I went about filing a report with IC3 and SCDCA. I gave him the links I used. I urged both other guys to file reports themselves, and I mentioned to the BBB in an addendum to my complaint, that I had found 2 other persons who have had similar dealings with Mr. Shull. That's about all I can do, is urge them to file, it's up to them to actually do it.
