This came up a few days ago in a post that mentioned using Campbells Alphabet Soup to fake Curtis Green's death. Enough people didn't seem to know about that that I think it warrants a repost. I didn't have the links at the time but I searched around and found them. Anyone who wasn't around at the time may want to read them, it's very interesting.

Also, for the record, the main sources of information for this article are Carl Force IV and Christopher Tarbell so the story is very much oriented and some "facts" should be taken with a grain of salt.
